Seeking Realistic Window Quotes in Largo (2010 Home) - Impact Costs vs. Keeping Shutters?

Welcome @rwilson45! We went through this last year, so I feel your pain on the sticker shock. I'm in North Tampa (house built 2008) and replaced 12 windows and two sliding glass doors in mid-2024. Our original windows were similar to yours (non-impact, builder grade). We had hurricane shutters as well, but got tired of the hassle and decided to go with impact windows for the peace of mind (and for the insurance benefits).
We got a bunch of quotes. The highest was actually Renewal by Andersen like you tried (they wanted about $50k for 15 openings, which we quickly passed on). Most mid-range quotes for impact vinyl windows (double-pane, Low-E, argon, etc.) came in around $1,200 to $1,600 per window, and our sliders were about $4,000 each. In total, we ended up paying roughly $30k for everything. We chose a local window company (not a big brand) that installed PGT Winguard vinyl impact windows. PGT is a popular brand down here for hurricane windows.

Going impact added maybe 15-20% more to the cost compared to non-impact windows, in our case. For us it was worth it because once we had all impact glass, we qualified for a nice discount on our homeowners insurance (make sure to get a wind mitigation inspection done after install). Plus, not having to put up shutters in a storm is so much less stress. If you already have shutters and don't mind using them, non-impact windows could save you some money, but double-check the price difference. Some companies gave us quotes both ways.

No major permitting issues for us in Hillsborough County. The contractor pulled the permit and it was pretty straightforward. The inspector just checked that the windows had the Florida product approval stickers and that they were installed properly (anchors, shims, etc.). It did add some permit cost (about $500 included in our quote for all those openings). Just make sure whichever company you go with handles the permit and inspection as part of the job.

As for materials: we went with vinyl frames. Our area is inland enough that corrosion on aluminum from salt air wasn't a huge concern, but even so, modern vinyl is pretty sturdy and energy-efficient. Aluminum frames can be stronger for large spans and might be slimmer profile, but they conduct heat a lot more. We liked vinyl for the better insulation. The PGT vinyl windows we got have reinforcements in them for impact. They look good and haven’t had issues with warping or anything in the Florida heat (so far at least!).

Warranty-wise, the windows came with a lifetime warranty on the frame and hardware, and I think 20 years on the glass (lifetime for us, 20 if we sell, something like that). Our installer also gave us a separate labor warranty for a few years. We made sure to get all that in writing.

Definitely get a few quotes. The pricing can vary a LOT. And don't be afraid to negotiate a bit or ask if there's any seasonal promotions. We got ours in the spring when business was a bit slower and managed to get a small discount. Good luck and keep us posted!

@rwilson45, I feel you on the high quote. We’re in Clearwater (Pinellas) and our home was built in 2012. We just went through window shopping and replacement this year. Renewal by Andersen gave us a similarly crazy quote (I think ours was like $30k for just 8 windows, absolutely not happening). It seems their quotes are always super high-end.
We ended up getting quotes from three companies: one from NewSouth Window (they have a big showroom in Tampa and make their own windows), one from a smaller local outfit, and one from a well-rated window contractor out of Clearwater. Prices were all over the place. NewSouth’s quote was about $18k for 8 windows (all impact, vinyl). The local independent contractor quoted around $14k for the same number of windows using PGT brand. We actually ended up going with the independent guy and PGT windows, which saved us a good chunk of money for essentially the same thing.

Since your house is 2010, you probably have shutters (sounds like you do). In Pinellas, when we pulled permits they asked if we had existing hurricane protection. If you choose non-impact replacements, you’ll need to either have those shutters or install some kind of approved hurricane protection for code. We opted for impact windows, though, even though we had shutters from the builder. It just feels more secure, and we won’t have to scramble to put shutters up if a storm comes. Our inspector did check that the new windows were impact-rated (each window had a sticker or etching with the approvals).

Permitting in Pinellas was pretty straightforward. It was an online permit our contractor handled. It took about two weeks for approval, then after install we had a county inspector come out and sign off. No issues, just took a little time waiting on scheduling. We did have to pay about $300 in permit fees (it was itemized in the contract). Make sure whoever you hire includes that and doesn't ask you to "pull it yourself" - I've heard of some shady companies doing that to avoid responsibility.

Oh, and on the materials: in our case we stuck with vinyl too. Almost all the quotes we got were for vinyl impact windows, actually. I think aluminum impact windows are more often used in really high-end or commercial jobs, or if you have giant window spans. For a typical home window size, vinyl is the norm here now.

Anyway, I think once you get a couple more quotes, you’ll find something much more reasonable than $45k. That first quote sounds like the “I don’t really want to do your job but if you pay this, sure” price 😂. Keep us posted!

Just to throw in another recommendation: I had my windows done by Karoly Windows & Doors (they're a local contractor in the Tampa Bay area) and had a really good experience. My home is in Seminole, built in 2005, and we replaced all 8 of our old single-hung windows with new impact windows last summer. Karoly's team was very professional and their quote was quite competitive compared to others I got.
For 8 vinyl impact windows (sizes ranging from small bathroom window to a large front picture window), we paid about $9,500 total. That included everything: permits, installation, removing the old windows, even repairing the stucco around the windows where needed. They used their own in-house installers (no subcontractors), which I liked because the quality of install was excellent. The owner (Karoly) even stopped by on day one to check measurements, which gave me confidence they care about the details.

I also liked that they weren't pushy with sales gimmicks. Another company I got a quote from was doing the whole “if you sign today we can knock 15% off” routine 🙄, whereas Karoly just gave me their price and let me decide when I was ready. Their windows have been great so far through one storm season – no leaks, noticeably quieter inside, and our energy bill actually went down a bit, likely due to the better efficiency and Low-E glass.

So, definitely give them a shot for a quote. In my experience, having a good installer is as important as the window brand itself. And a good local company will stand behind the work. (We have a lifetime warranty on the windows and a decent labor warranty as well.)

Good luck with your project! It’s a bit of a process but so worth it in the end, especially living here in hurricane country.

This thread is super helpful. I'm in Wesley Chapel (Pasco County) and in the process of getting quotes for my 2010 home’s windows. I haven’t pulled the trigger yet, but here’s what I’ve gotten so far:
Quote 1: Window World of Tampa Bay – about $11,000 for 10 windows (this was for their basic double-pane, non-impact vinyl windows). They said adding impact glass would increase it by around $4k. The price seemed low, but I'm a bit wary because I've heard mixed reviews about their quality and that there can be upcharges later.

Quote 2: ProTech Windoors – about $15,500 for 10 impact windows (vinyl, with Low-E). These guys were actually really informative. They walked me through the differences in glass and even talked about the permit process for Pasco. The quote includes permits and a lifetime warranty. I like that they're local and seemed very knowledgeable.

Quote 3: Some smaller local company (forget the name right now) – came in around $14k for 10 impact windows using Simonton StormBreaker Plus windows. We’re evaluating that one as well.

So far I’m leaning towards ProTech Windoors because even though they’re a bit more than the cheapest, they left a good impression (and a neighbor in our community used them last year and was happy). But I wanted to see if anyone here has experience with them or advice on those quotes. Do those prices sound in line with what others are seeing?

Also, curious about if it's worth getting triple-pane or anything fancy for energy efficiency, or is that overkill in Florida? All the quotes I got were for double-pane impact glass with Low-E, which I think is standard here. And since I'm in Pasco, my understanding is that impact isn't strictly required by code like it might be on the coast, but I'd still get some insurance break and of course peace of mind.

Thanks for any input! This thread has already given me some good pointers (like making sure permit fees are included and knowing about the insurance inspection after).

@rachelh71 I actually used ProTech Windoors for my window replacement two years ago (house in Land O’ Lakes, built 2006). They did 12 windows for me (all impact). I had a really good experience with them. The crew was on time, did quality work, and the owner even followed up after installation to make sure I was satisfied. It's been two hurricane seasons since and no problems at all - no leaks, no seal failures, everything still looks new.
Your quotes seem pretty much in line. I also got a quote from Window World at the time which was lower, but I was also a bit uneasy about the quality and some things in the fine print (their base price didn't include things like wrapping the exterior trim or disposing of old windows, if I recall correctly). ProTech’s quote was a bit higher but it was all-inclusive and I felt more comfortable with their product. They used PGT windows for my job.

I think paying a little extra for a company you feel good about (and that others have had good experiences with) is worth it, especially for something as important as windows. Sounds like your neighbor's recommendation holds true.

About the triple-pane: I asked about that too, and basically in Florida it’s not common. Double-pane with Low-E is usually plenty for energy efficiency. Triple-pane would make the window super heavy, and the extra benefit in our climate is marginal. It's more of a thing up north for extra insulation. My ProTech salesman actually said double-pane impact glass already makes a big difference for noise and heat, which I found to be true.

And you're correct about Pasco – you're a bit inland so you might not be required by law to have impact windows if you have shutters or if the wind zone isn't as strict, but having them will still give you some insurance credits (as long as all openings are impact). I'm in a similar boat; not coastal, but I still wanted the protection.

So yeah, I'd give a thumbs up to ProTech Windoors based on my experience. Good luck with your decision!

I’ll chime in with a slightly different approach. I replaced my windows last year too, but I actually went with non-impact windows and kept using my existing hurricane shutters. My situation: I'm in Riverview (Hillsborough County), house built in 2011. We had 10 original windows (cheap single-hung aluminum ones) that were in bad shape, but we had the metal panel shutters for each window stored in the garage.
I got quotes for both impact and non-impact options. The price difference was significant for me: roughly $11k for non-impact vs $15k for impact (for all 10 windows, from the same contractor, using the same brand minus the laminated glass). At that time I couldn’t comfortably afford the extra $4k, so I chose the non-impact, energy-efficient windows (double-pane, vinyl, Low-E) and decided I’d rely on my shutters for hurricane protection like before.

So far, I don’t regret it too much. The new windows themselves are a huge improvement in insulation and look nicer. And I did save money upfront. However, I will say every time a hurricane threat comes around, I do wish I had just gone impact 😂. Last year we had to put up the shutters twice (for two different storm threats), and it’s a workout and half a day of effort each time. Plus, you sit in the dark when the power goes out because the shutters block all the light.

Insurance-wise, since my new windows are not impact, I didn’t get the big credits. I still have the same wind mitigation credit as before because I have shutters (as long as you have either shutters or impact, you can get the opening protection credit). The inspector just had to verify that our shutters were still in place and rated, which they are. But if I had gone impact, I’d have the same credit and no need to mess with shutters.

If I could do it again and money allowed, I’d probably lean impact to make life easier. Maybe in a few years I'll upgrade if I can. But if budget is tight, non-impact windows + existing shutters is a viable path, just with those trade-offs in convenience. The key is if you do non-impact, you must have code-approved shutters or panels for every window to pass final inspection and to not void your insurance coverage. If you’re missing even one opening, you won’t get credit and you’ll have a vulnerability.

Just wanted to share that perspective, since not everyone ends up going the impact route. Either way, getting new windows has been awesome for reducing outside noise and improving AC efficiency. Even my non-impact glass has a nice Low-E coating and it made a noticeable difference this past summer.

Lots of good info here. I'll add my experience with a different window brand choice. I'm in St. Petersburg (house built in 2013). We replaced all the windows in our house this past spring. We had 10 windows and one sliding door. I got quotes that offered either PGT Winguard or CWS (Custom Window Systems) impact windows, which are both popular Florida-made products.
We ended up going with CWS impact windows through a local installer. The cost was around $1,300 per window on average (including install), and the sliding glass door was about $5k. In total, we paid roughly $20k for 10 windows + 1 slider. We did see slightly cheaper quotes for PGT from another company, but we really liked the installer who offered CWS, and they had a good reputation. From what I researched, CWS and PGT are pretty comparable in quality. CWS has been around a long time in Florida and their windows had good reviews, especially for coastal environments. They also offered a lifetime warranty on the frames and hardware, similar to PGT.

After installation, I can’t really tell much difference – impact windows are impact windows. They operate smoothly and feel solid. I did notice the CWS ones have slightly thicker frames, which means a bit less glass area compared to the old aluminum windows we had. It's not a huge deal, but something I noticed after the fact (vinyl frames are usually thicker than old aluminum frames to meet impact standards). On the flip side, the Low-E glass in these has been great at cutting down afternoon heat.

Our sliding door was a big upgrade too. We replaced an old drafty slider with an impact slider that has dual locks and it feels super sturdy. One thing: the impact glass is quite heavy. You can feel the weight when you slide the door or open a window, but you get used to it. Just a reminder to keep the tracks clean and rollers maintained so they glide easily.

We pulled permits with the city of St. Pete and it all went fine. The only hiccup was scheduling the inspection took an extra week because the city was a bit backed up at the time. But passed no problem.

So yeah, don't stress too much about choosing between good brands like PGT vs CWS vs Simonton – focus on a good installer. A good installer will make sure whichever window you choose performs well. We're really happy with how ours turned out.

Reading all these experiences, I want to add a little cautionary tale about shopping around. When we were getting quotes for our windows (house in Apollo Beach, built 2015), we had one company come out that turned into a bit of a nightmare sales pitch. I won’t name them, but they’re a large outfit that advertises heavily on TV/radio. The salesman was at our house for almost 3 hours, doing the whole song and dance with a slideshow, samples, and a bunch of “today only” discounts if we signed right then. The initial price he quoted for our 12 windows was like $40k 😳. By the end of the visit, with supposed discounts and phone calls to his manager, he had it down to $25k, but only if we signed that day. We did NOT sign anything, because the whole thing felt super high-pressure and gimmicky.
Later, we got quotes from two other local companies and both came in around $18-20k for the same work, no drama, no pressure. So just be careful with any company that won’t leave behind a written quote or tries to force you into a decision on the spot. A reputable contractor will give you a quote and let you think about it (maybe they have it valid for 30 days or whatever, which is reasonable).

In the end we went with the company that gave us a straight-up price (and it happened to be the lowest too). The windows (vinyl impact, Low-E, blah blah) have been great. So thanks to threads like these, I was warned in advance about those sales tactics and didn't fall for it.

TL;DR: Don’t be afraid to kick a pushy salesperson out of your house, and definitely compare multiple quotes!

One more thing to consider that I haven't seen mentioned yet: window style and any code considerations like tempered glass in certain spots. When we did our replacements (house in Brandon, built 2010), we actually changed a couple of our window styles. We had a pair of side-by-side single-hung windows in our kitchen, and we opted to replace them with one big horizontal slider (essentially a 2-panel sliding window). The installer had to combine the opening and put in a new frame to hold the slider, but it wasn’t a big deal. We just liked the idea of a clearer view and one large slider is easier to open for us than two separate narrow windows. They handled the permit for that, and it passed fine since we didn't change the width of the overall opening, just removed the center mullion.
Also, definitely mention to your contractor if you have any windows near showers, bathtubs, or doors. Florida (and everywhere, actually) building code requires tempered (safety) glass in certain locations (like if a window is within a certain distance of a door, or in a bathroom where someone could fall into it). Most impact glass is laminated and inherently meets safety requirements, but if you were doing non-impact, you'd need those specific windows tempered. Any reputable window company will know this and include it, but it’s good as a homeowner to be aware. For example, our bathroom window had to be tempered because it's above the tub, and our new patio door has tempered glass (plus laminate since it’s impact).

We also decided to have one small bathroom window made into a frosted (obscure) glass for privacy since we were ordering new windows anyway. So remember you can customize things like tint, obscurity, grids/no-grids when you order. We removed the colonial grids that were in our old windows to modernize the look – the wife and I are much happier with the clear view. Some companies charge extra for grids or different colors (like bronze frames), so factor that in if you want those features.

Our project went smoothly overall. Just had a tiny drywall crack above one window after install, but that was easy to patch. The installers told us sometimes the house shifts a bit when the old windows come out, especially if they have to pry them out, but they foam-sealed everything and it’s all good now.

Hope this helps think about some of the “small details” beyond just cost.

For those who have done it already: how long did you have to wait between signing a contract and getting the windows installed? I'm trying to plan around some other projects and wondering what kind of timeline to expect.
I know supply chain issues were a thing in the last couple years, though maybe it's better now. One company I spoke with said about 8-10 weeks lead time for the windows to be made (they order custom-sized windows for your house). Does that sound about right for the Tampa Bay area? And once they came in, how quickly did the actual installation happen? Did you have to live with boarded-up openings at any point or do they do it window-by-window the same day?

Just a bit nervous about having big holes in the house during hurricane season if there are delays 😬.

@jjones18 – good question about timelines. I just went through this in 2024 and can share how it went for us. Our timeline was: signed contract in early March, windows were delivered to the installer by mid May (so about 10 weeks), and installation started immediately after they had them all. We were scheduled for a 2-day install for 15 windows and 1 slider. They did about half on day one and half on day two.
They definitely won’t leave your house with open holes overnight. The crew made sure to only remove what they could replace the same day. So day one, they took out and installed like 8 windows, sealed them up, and cleaned up before leaving. Day two they did the rest plus the sliding door. The only time we had a "hole" was the few minutes between them pulling out the old window and fitting the new one in that opening, which they did one by one. If a surprise rain shower pops up (Florida life), they would just pause or do one at a time quickly. In our case, weather was fine and it was not an issue.

I think 8-10 weeks lead time is pretty typical right now if you’re ordering standard colors and styles. If you special order something like a custom exterior color or odd shape, it might take longer. After the install, you might wait another week or two for the final inspection scheduling, but that doesn’t affect your living situation, it’s just an appointment for the inspector to come check things.

One tip: if you're concerned about hurricane season, try to schedule the actual installation for outside of peak season if you can (like get the order in so install happens in spring or early summer). But even if it falls in say August, it's usually fine. Worst case, if a storm was literally coming on your install day, they’d postpone a few days. They won't leave you mid-project if a hurricane was approaching, of course.

So overall, plan on maybe 2-3 months from signing to completion in normal circumstances. And definitely do it when you have some flexibility in your schedule to be home during install days if possible, just to oversee and be available.

Really appreciating all the insights here. My situation's a little different: my home is on the coast (Redington Shores in Pinellas, built 2010). We haven't pulled the trigger yet, but we know we'll need to replace our windows in the next year or two, especially to get those insurance benefits and because the salty air has corroded some of the old window hardware.
One thing I'm curious about: do coastal homes like mine need any special window ratings beyond just "impact"? I heard that some areas require windows to meet certain wind speed ratings (like up to 150-160 mph). Our neighborhood is literally across the street from the Gulf. When I mentioned window replacement to a neighbor, they said make sure to get windows with the higher design pressure (DP) ratings due to how exposed we are.

Has anyone in a similar coastal spot done this recently? Are the standard impact windows (like PGT or CWS) okay for that, or did you have to get something extra like "HVHZ-rated" windows (I know Miami-Dade has special requirements)? I assume Pinellas follows the Florida Building Code for non-HVHZ, but being on the water is making me double-check.

Also, any extra steps for permitting in a coastal area? I’m not in a historic district or anything, but we are in a flood zone AE. Not sure if that affects window permits.

I plan to get quotes soon; just trying to gather knowledge so I ask the right questions. If anyone has insight on coastal requirements or recommendations for installers who do a lot of beach homes, I'd love to hear it!

@ejackson55 I’m in Indian Rocks Beach (Pinellas coast) and just replaced my windows last year. My house is older (90s build) but I think the requirements would be similar for your 2010 build, since code only got stricter. Yes, being on the coast means the windows we installed had to meet higher wind loads, but any impact window that's rated for Zone 4 (which covers much of Pinellas) should suffice. The key is making sure the product you choose has a Florida Product Approval and is rated for the design pressure (DP) needed for your exposure.
For example, the PGT Winguard windows we got have various models; the ones we used were rated for something like DP50 or DP60. Our permit paperwork had the specific product approval numbers. The contractor actually knew exactly what was needed when I told them my address; they said “we’ll use the higher DP rated frames and laminated glass that meets Miami-Dade specs” even though we’re not in Miami, just because we get similar wind gusts being on the Gulf. It didn't really cost more to get that version; it's just which screws and installation method they used and maybe slightly thicker glass.

We did get stainless steel hardware and fasteners due to the salt air - make sure to request that if you're coastal, or verify that's standard. Some cheap installs might use regular steel nails/screws which can rust out near the beach. My installers caulked everything with a special silicone sealant that's good for coastal conditions too.

Permitting wise, Pinellas County (and the beach municipalities) just follow FBC guidelines. Our town of Indian Rocks Beach required engineering documents for the windows (the contractor provided the FL Approval docs and installation diagrams). It wasn’t anything extra beyond what they'd normally submit, just that they had to note "Exposure D" (which is the coastal wind exposure category) on the permit form. The inspection was normal.

So bottom line: standard high-quality impact windows from top brands are usually fine, just ensure the installer knows you're coastal so they use the right materials and the product is rated for your wind zone. If you go with a reputable local window company, they'll automatically do this. But it's good that you're asking so you can double-check when reviewing quotes. Maybe ask each company, "Will these windows meet the wind requirements for a home on the beach?" and they should say yes and be able to show the rating.

Hope that helps. And definitely do it – the difference with new impact windows on the beach is huge. No more salt spray coming through tiny cracks, and way quieter inside even when the waves and wind are raging outside.

Quick note on warranties: make sure you understand who to contact if something goes wrong. I replaced all windows in my home in Odessa (Pasco County) in 2022. About a year later, one of the new windows developed a condensation fog between the panes (a seal failure). It was a bummer to see, but I was glad I chose a company that honors their warranty. I called up the installer (who also was the dealer for the window manufacturer) and they handled everything. They ordered a new sash from the manufacturer under warranty and swapped it out for me at no charge. It took a few weeks for the replacement sash to arrive, but the process was relatively painless.
Contrast that with my neighbor, who went with a different company that apparently went out of business a year after her install. She has a window with a similar issue and is now trying to deal directly with the manufacturer, which is slower and more paperwork because the original dealer is gone. She'll probably still get it replaced (the manufacturer of her window has a 20-year glass warranty), but it's more hassle.

So my advice: choose both a good product and a good installer who you expect to be around for a while. Lifetime warranties are only as good as the company backing them. In my case, I got a lifetime warranty on the windows and a 5-year workmanship warranty from the installer. I specifically asked how service is handled and they explained the process if glass breaks or if any seals fail, they take care of coordinating with the manufacturer.

Also check if the warranty is transferable if you sell the house, just in case. Some brands offer one-time transfer to a new owner (sometimes they require a fee to transfer). Might not be a big deal if you plan to stay put, but it's nice to know.

In summary, we've had one hiccup, but because of a solid warranty and company, it was fixed without costing us anything. Things happen, even with top brands, so good after-sales service matters!

For those who've done this, did you notice a big difference in your electric bill or overall comfort? I'm trying to justify the cost in my head. I know hurricane protection is one benefit, but I'm also hoping for energy savings (especially in our brutal summers).
My house is in Valrico (built 2014) and the builder-grade windows we have now are double-pane but I suspect not great quality (we feel a lot of heat through them in afternoons). If we go with high-quality Low-E impact windows, can we realistically expect much lower cooling costs, or is it just a minor improvement?

Basically, I'm wondering if the investment pays back a bit through energy efficiency, or should I treat it purely as an upgrade for safety/peace of mind and home value, and not bank on energy savings?

@zshadow38 Good question. In my case, we did see noticeable energy savings after our window upgrade, but I would call it a long-term payback, not something that will refund your project cost quickly. I'm in Palm Harbor (house built 2007). We replaced original single-pane windows with new impact double-pane Low-E windows in 2021. Those original windows were pretty bad (no tint, not much insulation), so our situation might be more dramatic than yours since you already have double-pane.
Before window replacement, our summer electric bills (with AC set around 75°F) were hitting $250+. After new windows, we saw about a 15-20% reduction in our monthly bills during the hot months. So instead of $250 it might be
200−
200−
210. It’s not like cutting it in half or anything, but that's still significant over time. Part of that could also be that we added some attic insulation around the same time, so not all due to windows, but I believe windows were a big factor because we immediately noticed the house staying cooler in the afternoons. The west-facing rooms were not heating up as much as they used to once we had the Low-E glass and argon-filled panes.

Even in winter (our winters are mild, but it does get into the 40s occasionally), the new windows have less draft. We used to feel cold drafts near some windows - now we don’t.

So yes, there is an energy efficiency benefit. I’d say treat it as a nice bonus rather than the primary justification. The primary reasons are usually storm protection, security, noise reduction, and aesthetics/home value. The energy savings over many years will offset some portion of the cost. If I crunch the numbers, maybe I'm saving a few hundred bucks a year on electricity. Over a decade or two, that adds up, but it's not a quick ROI by itself.

One more thing: if your current windows have no Low-E and you get new ones with Low-E, you'll likely notice your furniture and flooring fading less from UV light. We had noticeable sun-fading on our hardwood floor by the big sliders before; after installing the new glass, it seems to have slowed that down. Harder to quantify, but it's a plus!

In summary, expect some savings and comfort improvements, but the "payback" is gradual. Even without massive energy savings, though, I've been very happy with the upgrade for all the other reasons (storm peace of mind especially).

I'll add an often-overlooked step: if you live in a neighborhood with a homeowners association (HOA), don't forget to check their rules before replacing windows. I'm in a subdivision in Tampa Palms (Hillsborough County), and our HOA required an approval for any window style changes. They wanted to make sure the exterior look remained consistent (frame color, grid pattern, etc).
In our case, we had white frames with colonial grids in the old windows. We wanted to switch to no grids for a cleaner look. The HOA actually was fine with removing grids (turns out lots of neighbors have been doing that), but they required that the frame color remain white (no bronze or other colors visible from the street) to maintain uniformity. We also had to submit the product brochure showing the windows we were going to install, just so they could verify it didn't drastically alter the appearance. It was a pretty quick approval once we turned in the form, but it's something to factor in your timeline. If we had skipped that and just installed, we could've gotten in trouble with the HOA.

Another neighbor in our community did bronze frames and the HOA made them paint the frames white again or replace them, which was a costly mistake for them. So yeah, definitely check any architectural guidelines.

On the permitting front in Hillsborough: the county permit was pulled by our contractor and we didn't have to do much. But the HOA step was on us to handle and prove we had permission. The window company actually asked if we had HOA approval during the quoting process, so that was a helpful reminder.

Just something to keep in mind for those in deed-restricted communities – add HOA approval to your to-do list.

Wow, thanks so much everyone for the detailed responses! This has been incredibly helpful. 😊 Hearing real numbers and experiences from fellow Tampa Bay homeowners is exactly what I needed.
Update from my side: Since my first post, I’ve gotten a couple more quotes in. So far I have:

Karoly Windows & Doors – came out to my house and quoted $12,300 for 10 windows + 1 slider (all impact, vinyl, Low-E). This includes everything. The rep was fantastic – very thorough and zero pressure.

ProTech Windoors – came out next week and gave me an estimate of $13,000 for the same scope. Also very professional.

Local Contractor (non-impact) – A local independent installer estimate was around $7,500 for non-impact windows + slider, and he noted adding accordion shutters would be about $3,000 more, so roughly $10.5k if I go that route for full protection.

So interestingly, going non-impact + accordion shutters versus full impact is only a couple thousand cheaper in my case ($10.5k vs
12.3k−
12.3k−
13k). Given this, I’m definitely going with impact windows and skipping the shutters entirely. It seems cleaner and less hassle long-term.

Now I’m basically deciding between Karoly and ProTech. Both have similar pricing and both left a good impression. Karoly is a tad lower in price and offered slightly sooner installation scheduling, so I’m leaning that way. Plus, some of you here (looking at you @donaldevans5 and others) have had great experiences with Karoly, which gives me confidence. ProTech also sounds great (@environment_jon and @architecture902 shared good experiences). Honestly, I feel either one would do a good job.

Does anyone see any red flags or have any last-minute advice before I pull the trigger? Otherwise, I think we’re going to go with Karoly and get all impact windows. I’ll definitely let you all know how it goes once they’re installed! This thread has been a lifesaver in making this decision – thank you all again!

Figured I'd add my experience as another data point, especially for those with relatively new homes. My house was built in 2015 in Lutz (Hillsborough/Pasco line) and by 2023 I already had two window seals fail (fogging between panes) and one window that wouldn't stay up (balance broke). The builder-grade windows just didn’t hold up, likely because they were the cheapest available at the time. I limped along with those issues until I finally decided to do a full replacement of all windows this year.
I replaced 11 windows with vinyl double-pane (impact) windows from a local installer. Cost was about $11,800. Honestly, part of me was annoyed I had to do this so soon on a relatively new house, but the difference in quality is night and day. The new windows slide like butter and the latches and hardware feel much sturdier. No more condensation issues either.

I tried to get the builder to address the failing windows when it first started happening (around year 5 or 6 of the house), but of course by then we were out of their standard warranty. The window manufacturer (some no-name brand) technically had a 10-year warranty on the IGU (insulated glass unit), but getting service was nearly impossible. They didn't have a local rep, and I gave up after a lot of runaround. That's when I decided to just spend the money and get better windows that have local support.

So for anyone with a newer home: don't assume your windows are great just because the house is newer. Builders often use mediocre windows. If you notice issues like drafts, fogging, or difficulty operating them, it might be worth upgrading sooner rather than later. It stinks to shell out more money on a newer home, but in my case I'm glad I did it now rather than dealing with incremental problems each year.

On the bright side, I was able to sell a couple of the old windows that were still okay on Facebook Marketplace (somebody wanted them for a shed) and got a tiny bit of money back 😂. And the house feels more "solid" now with the new ones. Just my two cents for others in a similar boat.
