What I Wish I Knew Before Replacing My Windows in Tampa Bay

Energy efficiency FTW! We also saw a drop in our cooling costs after window + insulation upgrades. It’s really satisfying to see those numbers go down for a change, isn’t it? Also, @rockysinger, good call on inspecting deliveries. Our windows came straight on the morning of install in a big truck, so I didn’t have a chance to pre-inspect. But the crew leader did a check as they unloaded and noticed one was wrong size (like you experienced). It was a bathroom window that came too small. They boarded that opening and we waited about 10 more days for the correct one. Minor hassle, but I’m glad the crew was on the ball. If I ever do this again, I’ll definitely be proactive in checking everything.
Another minor thing I’ll add: the sticker removal. All our new windows had those big NFRC/energy code stickers on the glass. After install, I spent an afternoon peeling them off and scraping adhesive. A little rubbing alcohol or Goo Gone helped get the residue off. It’s trivial, but I wish I had asked the installers to remove them – some did, some they left on. Not a huge deal, but just adding to the list of “little things you don’t think about.” 😉

By the way, this thread really should be pinned or something. It’s the most useful set of info on Tampa window replacement I’ve ever seen in one place!

Quick update from my side as well (6 months post-install now): everything’s holding up great. We went through a rainy season and a tropical storm with no leaks – I was nervous the first big rain, but the windows and the install passed the test. 🎉
One small issue did pop up: a couple of months in, I noticed a tiny gap in the caulking on one window where the frame meets the exterior stucco. Probably due to the building shifting or the caulk settling. I ran a bead of silicone caulk over it myself (color-matched, not that anyone but me will ever notice). No more gap. So my tip is to do a walk-around inspection every few months in the first year to catch any little caulk separations or settling issues. Florida’s heat and summer thunderstorms can be tough on sealants, so a little maintenance goes a long way.

Also, I have to second what others have said about new windows being a bit tight initially. Even 6 months later, our large sliders still need a firm push to get moving. The installer told me to spray a dry silicone lubricant along the tracks if needed. I did that and it helped a lot. Now they slide smoothly but still seal tight. So don’t fret if your windows are hard to open at first – that can be normal.

Overall, zero regrets. I actually enjoy the sound of not hearing much sound, if that makes sense. 😄 Our condo is right by a busy part of the beach and the difference in noise is astonishing.

I haven’t seen anyone talk about older historic homes, so I’ll chime in. My house in Tampa Heights was built in 1925, and we replaced the ancient wood windows last year. That was an adventure:
Historic District Rules: Because our neighborhood is in a historic overlay, I couldn’t just put in any modern-looking window on the front facade. We had to get windows that look like the originals (in our case, wood windows with the same grid pattern) or the historic committee wouldn’t approve it. I wish I knew about this earlier because it limited our choices and increased cost. We ended up with wood-clad windows for the front (expensive), and we used more affordable vinyl double-hungs on the sides/back where it’s not visible from the street. So if you’re in an old neighborhood, check any historic preservation guidelines – you might need specific materials or styles.

Removing Old Weight Pockets: Our original windows had those pulley and weight counterbalances (old school tech!). When those came out, there were hollow cavities on each side of the window frame. The installers actually filled those voids with foam insulation before putting the new window in, which is great for energy efficiency. But one window had some surprise termite damage in those pockets. We had to get a little framing repair done there and I had a termite treatment done around that area afterward. Was not expecting to deal with pest control during a window job, but with old houses, anything can happen once you open things up. Heads up to anyone with very old wood windows: be prepared for hidden issues like rot or pests.

Interior Trim: We had beautiful wide wood casing trim around the windows inside. I was worried it’d get ruined. The crew was super careful and managed to take most of it off and reinstall it without damage. I did have to repaint the trim after, but at least we kept the original look. If you have old molding you love, discuss it with your installer. A good one will try to save it.

At the end of the day, our old house still looks historic (we maintained the divided-light look on the front windows), but performs like a modern one with the new windows. No more drafts – it used to feel like the wind was blowing right through the closed windows on cold nights. And outside noise is so much less, even with wood windows (we got double-pane in the wood as well). It was a hassle navigating rules and some extra repairs, but worth it. Just wish I’d known about the extra red tape and potential for surprise repairs – I would have budgeted a bit more time and money.

@phill68, thanks for sharing! I’m in a 1930s bungalow in Seminole Heights considering window updates, and the historic look is a big concern for me. Did you go with a specific brand of wood-clad windows for the front? And how did they compare cost-wise to the vinyl ones in the back (if you don’t mind my asking)?
Also, I have those weight pockets too and I’ve been nervous about what’s inside (hoping not termites like you had!). Sounds like foam filling is the way to go once they’re out.

@markbaker838 – We ended up choosing Jeld-Wen wood clad windows for the front (they have an aluminum cladding on the exterior for durability, but wood inside). They have the option to add the old-school grille design. They were about 2x the price of a standard vinyl window of the same size. For example, one front window roughly 30”x48” was about $1,000 (wood clad), whereas a similar vinyl one for the side was around $500. So definitely a premium for that historic look.
The historic review board was mainly concerned with the exterior appearance. They approved the aluminum cladding because it was a similar color and had the same muntin (grid) pattern as the originals. If I had gone full vinyl on the front, I doubt they’d have approved – vinyl frames often are thicker and would change the look too much.

In terms of performance: those wood windows are actually slightly less airtight than the top-notch vinyls we put in elsewhere (I can feel a teeny draft if it’s super windy, whereas the vinyls are airtight). But they still are way better than the old single-pane wood ones.

And yes, definitely fill those weight pockets with insulation when they come out. It’s like gaining two mini wall insulation sections you never had before. Our bedrooms feel less drafty now thanks to that.

Good luck with your bungalow! It’s a balance of preserving character and modernizing comfort. It can be done, just takes some extra legwork.

@phill68 Yikes, termites in the window frame – that’s a Florida special surprise right there. Glad you caught it. Reading that, I just made a note to self to spray some preventative termite treatment around my window frames now that I have things freshly sealed up.
Also, thanks for sharing the historic angle. Not my situation, but super interesting how you blended old and new. And I hear you on old windows being drafty; I don’t miss that at all.

One small thing I’d add from my experience: think about the aesthetics and functionality of things like window grids (grilles) and screen types before you order.
When we replaced our windows, our old ones had those colonial grids (divided squares look). We were tired of that and opted for clear, unobstructed glass on the new windows – no grids at all for a more modern look. It looks fantastic and really opened up our view. Buuut, our house went from looking classic to a bit more contemporary, which we like, but one of our neighbors actually asked if we were going to add grids back because it changed the look. (Nosy neighbors, haha.) The HOA didn’t require grids, so it’s fine, but I realize now it gave the house a noticeably different appearance.

I personally love the clearer view. Cleaning is easier with no grids, too. But if I were in a super traditional style home, I might have kept some grids for character. Another friend of mine did the opposite: her old windows had no grids and she added grids in the top sash of her new ones for a craftsman look.

So my lesson: decide on grids or no grids based on the look you want long-term. It’s something you can’t change later without replacing the sash or entire window. I spent so much time on glass choices and frame color that I underestimated how the grid decision would impact the look.

Also, about screens: I didn’t realize there are options (half screens vs. full screens on double-hung windows, for example). Ours came with half-screens (only the lower half where the window opens is screened). It’s fine for us and actually lets more light in through the top half since there’s no screen there. But if you like to open both halves of a double-hung window, you’d want a full screen. Just something to think about. Our installer defaulted to half-screens and we didn’t even discuss it. In hindsight, I’m okay with it, but some people might prefer full coverage. So ask about that too!

Our project went mostly smoothly, but here’s a lesson from a mismeasurement fiasco: double-check your window measurements (or rather, have the company re-measure before ordering).
The salesperson from one company measured all our windows for the quote. After we signed with them, they sent out their expert to take final measurements (thankfully). Guess what – one big living room window was recorded wrong by a couple of inches in the initial quote. If they hadn’t double-checked, the window ordered would have been the wrong size and not fit. 😬

Even with the double-check, we still had a hiccup: one smaller window was made 4 inches too tall due to some confusion with how they measured the rough opening. They only discovered this on install day when it literally wouldn’t fit in the hole! The crew had to board that opening up and rush-order the correct size. We slept with plywood in that window for two weeks, which was… not fun.

So my advice: if possible, be present for the measurement phase and ask the rep or tech to confirm critical dimensions. When you get the invoice or order sheet, check the sizes listed if they provide them. In our case we didn’t see the final sizes until the window showed up and had a label with dimensions.

Most good companies will do an official re-measure like ours did, but mistakes still happen. Had I known, I would have politely asked, “Are you sure that’s right? Can we verify?” on that one window that looked oddly sized on paper. I’m not saying measure it all yourself (that’s their job), but a little extra attention could save delays.

The saying “measure twice, cut once” exists for a reason – or in this case measure twice, manufacture once. 😅

One more piece of advice that I haven’t seen emphasized enough: before the installers pack up and leave, do a thorough walkthrough and test everything.
I know @matthewcoder3090 mentioned a checklist, but I want to reinforce how important this is with my personal story: After our install, I did a walkthrough with the crew and found two issues:

One of the bedroom windows wouldn’t lock properly. The latch was not aligning with the catch. The installer realized the window needed a slight adjustment in how it was shimmed. He took about 10 extra minutes to tweak it, and boom, it locked smoothly.

A tiny gap in caulking on an exterior frame – it was hard to see, but I noticed a little sliver of light when I was outside inspecting. It turned out they missed caulking a 3-inch section at the top of one window. Easy fix on the spot when I pointed it out – they hit it with silicone before putting away the ladders.

The installers were super nice about it, but I got the impression that if I hadn’t caught those before they left, it might have been a hassle to get them back out later for such small things. They had me sign off that the job was completed to my satisfaction, so definitely don’t sign until you’ve checked everything.

Test every window: open it, close it, lock it, unlock it. Look at the caulking lines around each window inside and out if you can. Make sure any screens are in and not bent, and that they slide if they’re sliders. Minor things can be fixed in minutes while the crew and tools are there, but can become a headache if discovered days later.

I know by the end of an install day you might be exhausted (I was) and just happy it’s done, but that 15-minute check will ensure no lingering issues. After all, you’re paying good money – you deserve a perfect (and complete) job.

Piggybacking on the screens mention by @psage55 – it’s true, not all screens are the same, and it can be an oversight if you don’t discuss it.
Our double-hung windows came with half screens by default. That’s fine for us because we usually only open the bottom sash. But one thing I didn’t realize: half screens mean the top half of the window has nothing when the window is closed, which looks a bit cleaner (nice), but if I ever want to open the top half for ventilation (like dropping the top sash down), I can’t unless I physically move the screen up or get a full screen. Some window designs let you slide the half-screen up and down; ours don’t – they’re fixed at the bottom.

It’s a small detail, but worth knowing. If you love maximum airflow or tend to open the top, consider asking for full screens. Some companies might charge a little extra for full screens on double-hungs.

On sliders, we had one slider window that oddly came with no screen at all! I pointed it out and the installer realized the manufacturer forgot to ship one. They had to order a screen after the fact. We went a few weeks unable to open that window (didn’t want bugs coming in). Lesson: make sure every window that should have a screen has one installed before the job is done.

In Florida, the last thing you want is a window without a screen when the weather’s nice – the mosquitoes will swarm in uninvited. 🦟 The company made it right and got us the screen, but I was annoyed I had to ask.

Now I’m enjoying breezes without bugs, and the half vs. full screen thing isn’t a big issue for us day-to-day, but definitely something to decide on when ordering.

Haha, I’m glad someone brought up pets earlier. Let me underscore that with my little saga: on installation day, our indoor cat escaped through a giant window opening! 🐈😱
We thought we had him closed in a back bedroom, but during the chaos he slipped out. At one point I walked by the living room and saw no cat – next thing I know, I spot him in the front yard sniffing around (probably thought we installed a big new cat door just for him). I had to calmly approach so I wouldn’t spook him into running, and luckily I scooped him up and back inside quickly. But it gave me a heart attack. From then on I actually put a big note on the door of the room he was in: “DO NOT OPEN – CAT INSIDE” for the workers, and I kept him in there for real.

Also, consider the noise impact on pets. My dog was trembling from the strange noises and commotion. In retrospect, I should have taken both the cat and dog to a friend’s or a boarding for the day. It would have been less stressful for everyone.

For families with kids: my toddler was fascinated by the workers and wanted to “help.” Definitely had to keep a close eye – we ended up having grandma take him out for a “special day” so we could focus on the project. Best decision ever.

So secure your pets and kiddos – double-check those closed doors and maybe put them in a part of the house that isn’t going to be accessed, or better yet, have someone watch them elsewhere. Even the most chill pet can bolt when their familiar home suddenly turns into a construction zone.

In the end, all humans and animals were safe and sound, and my cat is back to gazing out of closed windows only. But I learned my lesson!

Reading the hurricane timing discussion, I wanted to share our little nightmare-turned-okay story: We scheduled our window install for late August (yeah, height of season, but it was when we could do it). Sure enough, halfway through the project, a tropical storm decided to swing by the Gulf. It wasn’t a direct hit on Tampa, but we were getting feeder bands with heavy rain and wind.
Picture this: three windows out, just open holes, and the sky turning dark. The install crew watched the radar like hawks. The moment it looked nasty, they paused installation and did an emergency board-up. They had plywood ready (thank goodness) and secured those openings in no time. We rode out an afternoon of howling wind with plywood in place of windows. Not going to lie, it was nerve-wracking seeing rain slam against those makeshift covers, but they held.

The next day, the weather cleared and the crew got back to work, replacing the plywood with the new windows. No water got in, and everything ended up fine. But lesson learned: avoid that scenario if you can! It was more stress than I’d like during an already stressful project. Our installers were awesome for being prepared and acting fast.

So, if you have to install in summer, maybe have a conversation with the installer: “What’s your plan if a sudden storm pops up?” A good company will have a procedure. Ours said they always keep boards or plastic sheeting handy for each opening until the new window is in.

Now we joke that our windows got an early hurricane test (even before final caulking). They passed with flying colors, but I’ll plan for a winter install next time, thank you very much. 😅

On the topic of hurricane tests – I can vouch that impact windows really do their job. We had our new impact windows for about a year when Hurricane Irma (2017) grazed Tampa. During the storm, a tree limb from my neighbor’s oak slammed into one of our big front windows. I heard it bang and honestly thought the branch came through. Ran out after the worst passed and saw the outer pane of our double-pane impact window had a huge crack across it, but the inner pane was intact and no water inside. The branch was on the ground.
It was a mess to get that window pane replaced (took a few weeks due to everyone having post-hurricane repairs), but nothing – and I mean nothing – got past that window during the storm. If we had our old original windows, I’m pretty sure that branch would have been in my living room.

So for those wondering if impact glass is just hype: it may still crack under force, but it won’t shatter into your home. It’s like a car windshield: broken but held in place. We had to board it up after the storm until the glass company swapped out the cracked pane, but insurance helped cover it since it was storm damage and we had the proper hurricane-rated windows (no claim issues at all).

After that experience, I’m a huge believer in impact windows. It’s not just about pressure and wind, but flying debris. That peace of mind is real.

Something I didn’t fully appreciate beforehand was the cosmetic boost new windows would give our home. We focused so much on the functional benefits that it was almost a surprise how much better the house looked afterward!
Our old windows had aluminum frames that were faded and a bit chalky-looking, with some foggy glass in places from failed seals. Replacing them with new crisp white vinyl windows made the whole house exterior look cleaner and more modern. Even our neighbors commented that it’s like the house got a facelift. If I had known the curb appeal would improve this much, I would have been excited about that aspect too (instead of just dreading the project hassles).

Inside, the views are nicer too. We opted for a slightly larger window in our kitchen (turned a 3ft window into a 4ft one) and having that extra glass area brings in more light and a better view of our garden. It’s such a joy now to open the blinds in the morning.

I guess the lesson is: not only will your house feel better, it will likely look better, inside and out. For anyone on the fence, consider the aesthetic upgrade you’re giving your home, not just the practical upgrades. It helped us justify the cost in a way, knowing it wasn’t just an invisible improvement but a visible one too.

Plus, new windows can increase your home’s value. Several realtors have told me that replacement windows are a great selling point (energy efficient, wind-rated, etc.). Not that we’re selling anytime soon, but it’s nice to know we likely recouped a good chunk of the cost in added home value.

Haha, @elizabethhill590 I felt that on the stickers! I spent a solid two hours scraping off those darn factory stickers from each window. Pro tip for anyone yet to do this: use a razor blade scraper and some soapy water or Goo Gone. The soapy water trick worked well for me – wet the sticker and slowly scrape, it comes off in slivers but at least it doesn’t stick as bad.
One window’s label had baked on in the sun and was super stubborn. I joked that it had better ratings so maybe I should leave it for visitors to see our fancy energy-efficient windows. 😆 But no, those stickers had to go.

Minor issue in the grand scheme, but it’s one of those little “chores” after the installers leave that I didn’t anticipate. I assumed they’d remove them, but apparently not always. If I were doing it again, I might ask the crew, “Hey, will you take the stickers off the glass before you go?” It’s such a small thing but saves an annoying task later.

Anyway, I’m sticker-free now and enjoying the clear view. Just another tiny lesson: those finishing touches are usually on the homeowner. At least I got a mini arm workout scraping them, haha!

I want to emphasize a point about caulking and sealing with a quick story: A week after our windows were installed, we had a typical Florida torrential downpour. I did my usual inspection of all windows (still in honeymoon phase with new windows, checking them constantly). To my dismay, I found a small puddle on the inside sill of one bedroom window. 😧
My heart sank – leaking new window?! I called the installer in a panic. They came out pretty quickly. Turns out, it wasn’t the window failing; it was a missed caulking spot on the exterior. Basically, there was a tiny 1-inch section along the top that hadn’t been caulked at all (the installer either forgot or the caulk didn’t squeeze in properly). In normal rain it might not matter, but in a wind-driven rain, water found that little gap and made its way in.

They recaulked that area and a few others around that window for good measure. Next rain, no leak at all – dry as a bone.

Lesson learned: after installation, do a thorough check of the caulking around each window. It can be hard to spot gaps unless you look closely. I walked around the house, running my hand along the edges of all windows to feel for voids. That one window was the only issue, thankfully.

The installer was very apologetic and fixed it, but it reminded me even pros can miss a spot. And Florida rain will exploit any weakness! So give all your windows a good once-over from the outside. If you’re not comfortable getting up on a ladder to check second-story windows, use binoculars from the ground – seriously. It sounds extra, but a 5-minute scan could save you a water stain on your drywall later.

Since a few people have mentioned insurance, I’ll add on with my experience on how to maximize your homeowner’s insurance benefits after window replacement:
Definitely get a Wind Mitigation Inspection done once your new impact windows (or shutters) are in place. This is a special inspection in Florida where a certified inspector checks your home’s hurricane resistance features – doors, windows, roof tie-downs, etc. They’ll produce a report that insurance companies use to apply discounts.

Before we got new windows, our wind mit report showed “unprotected openings” because we had old standard windows with no shutters. After installing impact windows, I hired an inspector (cost was about $85) to do an updated wind mitigation inspection. He confirmed all openings are now protected. I sent that report to my insurance company and our premium went down by about $600 per year! It was a significant drop, basically the insurance company saying “okay, your house is less likely to suffer catastrophic damage in a hurricane now.” Over the life of the windows, that insurance savings will add up.

Important: Insurance won’t automatically give you the discount just because you got permits or whatever. You need that report. So budget an extra hundred bucks or so for the inspection as part of your project cost – it’s totally worth it. And do it soon after the install, so you start saving ASAP.

Also, some insurance carriers give credit for “opening protection” only if all openings are protected. So if you, say, still have an old garage side door or something that isn’t impact-rated or covered, they might not give the full credit. We had to also replace our outdated garage side door or put a shutter on it to qualify as fully protected. Just something to be aware of – to get maximum discounts, every window, skylight, exterior door, etc., needs to be impact or have a rated shutter. We went the extra mile and did an impact-rated front door at the same time as windows, partly for this reason (and partly because the old door was ugly, haha).

In summary: don’t forget the paperwork after the hard work. Wind mit inspection = insurance savings = money back in your pocket.

Interesting bonus I noticed post-window-install: my allergies got better. I usually get a lot of dust/pollen allergies, and I realized after we put in our new tight-fitting windows, I had fewer sneezing fits when the pollen count was high.
Our old windows were so drafty I think they were letting in allergens even when closed. I used to find fine dust on the windowsill every week. Now, hardly any dust accumulates there. The new seals keep out not just air and water, but the dust and pollen too.

I also used to wake up with a stuffy nose often, which I suspect was due to who-knows-what coming in from outside overnight. With the new windows, that’s improved. It’s not something I expected or even thought about – but for fellow allergy sufferers, it’s a nice fringe benefit.

So, what I wish I knew: new windows can improve your indoor air quality. Less draft, less outdoor crud entering the home. I still run an AC and filters for allergies, but every little bit helps. If anything, it reinforced that the old windows were not just an energy liability but maybe a health one for me.

Now if only it also stopped my neighbor’s BBQ smoke from wafting in when I open them for fresh air… but hey, can’t have everything! 😅

After you get through the install and initial excitement, don’t forget that windows need a bit of care over the years to keep them performing their best. A few maintenance tips I’ve gathered (some mentioned already, but here’s a little checklist style):
Keep Weep Holes Clear: Most windows (especially sliders and single-hungs) have small drain holes on the exterior bottom of the frame. These allow rainwater to exit the track area so it doesn’t overflow inside. Here in Tampa Bay with our heavy rains, those weep holes are critical. Check them occasionally and poke them clean with a piece of wire or a toothpick if you see dirt or insect nests clogging them. I check mine every few months, and after a big storm.

Lubricate Tracks and Hardware: As some have noted, windows can be stiff at first. A spray of silicone lubricant in the tracks works wonders. Avoid oily lubricants that attract dirt. Also a tiny drop of lubricant on moving parts of locks or cranks (if you have crank-out casement windows) keeps them operating smoothly. I do this annually or if I notice any sticking.

Inspect Caulking and Paint: Florida sun can bake caulk and paint. Every year, do a quick visual of the caulk lines around your windows. If you see any cracks or separation, touch it up with a good exterior caulk to prevent water intrusion. Same for any paint on trim or stucco around windows – a quick touch-up can seal hairline cracks. It’s preventative care that will help your windows last without leaks.

Clean Glass and Frames Properly: When cleaning your new windows, don’t use anything too abrasive. Warm soapy water and a soft cloth for frames (especially vinyl – no harsh solvents on vinyl or you could dull it). For glass, standard glass cleaner is fine, or vinegar water for a streak-free shine. Avoid pressure-washing directly on windows at close range – it can damage seals and force water where it shouldn’t go (learned that one the hard way on a neighbor’s window – blew a seal).

These are small chores, but a little TLC will keep those expensive new windows looking and working like new. We invest in them, might as well maintain them!

One more hindsight insight: be prepared for minor cosmetic repairs around your windows after the replacement. Even with a great install crew, some touch-ups are pretty normal:
In my case, a couple of interior sills got nicked during removal of the old windows. The old sill was painted wood and one split when they pried out a stubborn window. The installers replaced the piece of wood, but left it primed white. I had to paint it to match the trim (small hassle, but I wasn’t expecting it, so add another item to the post-project to-do list).

On the exterior, our house is stucco. Taking out the old windows caused a few cracks and chips in the stucco around the openings. The window quote included basic patching – they did fill the gaps with stucco mix – but those patches were obvious gray spots against my cream house until I painted them. I spent a weekend on a ladder carefully painting around each window to blend the patches. Now you’d never know, but initially I was a bit concerned seeing chunks of stucco missing and then new concrete patches. The foreman told me it’s almost impossible to avoid when prying out windows set in stucco, especially if the old caulk was brittle. Knowing that upfront would have saved me some surprise. It’s all fixable stuff, just factor in time/effort to do those finishing touches (or negotiate it into your contract if you’re not up for DIY painting).

The good news: once the paint was touched up and the new caulk lines were neatly done, the windows looked like they’d always been there – natural part of the house.

So, don’t be alarmed if your surrounding drywall or stucco looks a bit rough immediately after. A little spackle, caulk, and paint, and it’ll be pristine. If you’re not a DIY person, you might want to hire a handyman or painter for a day after the window crew is done to get all the details perfect.
