Tampa Bay Replacement Window Warranty Comparisons and Experiences

@ejackson55 Sounds like you’re on a great track. Both Karoly and ProTech are excellent choices, so you likely can’t go wrong either way. If Karoly gave you a solid price and you’re comfortable with them, that’s fantastic. Their warranty is about as good as it gets, really.
As for last checks:

Definitely get the warranty details in writing (the contract should include or reference them). But since they have a standard package (and @marks96 mentioned they give a packet), you should be fine.

Asking for references: you could, although hearing @marks96 and others here might suffice as references 😄. Karoly might also have a project portfolio or let you see an installation in progress if you wanted, but not sure that’s necessary.

Permitting and code: Just ensure (and I’m sure they will) that they pull the proper permits for the job and everything is up to current code (impact windows, egress where needed, etc.). Reputable companies always do, but it’s good to confirm you won’t have any surprises with inspections.

Negotiation: Companies like Karoly and ProTech aren’t known for haggling heavily (they market themselves on quality and fair pricing), but it never hurts to ask if there’s any current promotion or if they can do something about the price. Some might throw in small perks – like a free upgrade on hardware or an extra screen – but I wouldn’t expect a huge price drop. Given their quotes are competitive already, they likely price pretty firmly. The fact that Karoly’s quote was reasonable tells me they probably gave you a good price from the start.

When I dealt with Karoly, I found them to be straight shooters – not much gamesmanship on pricing. Same with ProTech’s style. They might have seasonal promotions (e.g., some do a discount if you sign by end of month, etc.), but again, don’t feel pressured by any “sign now” deals unless you’re truly ready.

I think you’ve done your due diligence thoroughly. At this point, it’s about pulling the trigger with the company you feel best about. And it sounds like you have that in Karoly.

Keep us posted on how it goes!

I want to share a quick story about actually using a warranty, since @ejackson55 asked for that. I had to make a warranty claim on a window about 7 years after install. This was in my previous home in Seminole. We had vinyl, double-pane windows installed by a local company (not a big name like those mentioned here, but a decent medium-sized outfit). The windows were Simonton brand.
About 7 years in, one of the large picture windows developed a fog between the panes – classic seal failure. Simonton’s warranty for original owner covered insulated glass seal failures for life (double lifetime for second owner). I contacted the installer, but by that time the original installer had actually gone out of business (yikes). However, Simonton as a manufacturer was still around (they’re huge nationally). I ended up calling Simonton’s customer service directly.

They honored the warranty without much fuss. They asked for some info (serial number/ID from the window, photos of the fogging). Once confirmed, they shipped a replacement insulated glass unit (basically the glass panes) to a local distributor. The tricky part was getting it installed – since my installer was gone, I had to find another window company willing to do the labor. Simonton covered the cost of the glass unit under warranty, but not the labor. I paid a small fee to a local handyman/installer to swap the glass (it wasn’t too hard as it was an insert).

So the warranty worked – I got a new glass for free – but because labor wasn’t covered after year 1, I did pay out of pocket for the install of that glass (which was maybe $100 or so). If my original installer had still been around and if I had a labor warranty with them, maybe it would’ve been free all around.

Lesson from this: Manufacturer warranties can be lifesavers even if your contractor vanishes, but you might incur some labor cost unless you had, say, a lifetime labor agreement with another company.

It made me appreciate companies that stay in business and those that offer to help facilitate warranty claims even many years later. Some will do that labor for a fee, others as a courtesy.

So yeah, warranties do get used and in my case, it worked out pretty well – just a minor hassle. Keep all your warranty paperwork and window serial numbers recorded, just in case!

I have a somewhat cautionary tale from a coworker: He had windows installed by a small local manufacturer/installer (a less known name, not one of the bigger players). They gave him a 10-year warranty on everything. Well, around year 9 one of his windows had a crack in the frame (not from impact, just a stress crack). He went to contact the company and... they had changed ownership or were bought out, and the new company didn’t honor the old warranties. 😟
He ended up having to pay for a repair himself. It wasn’t outrageously expensive, but it negated the warranty promise. He was pretty upset.

This echoes what folks have been saying: a warranty is only as good as the company behind it. It made me personally lean toward known manufacturers (so at least product issues can go to a big company) and installers with proven track records.

When I replaced my windows last year, I chose ProTech Windoors largely because of their reputation for service (and they’ve been around a while here). I figured even if, knock on wood, something happened to the product manufacturer, ProTech would try to “make it right” in some way, and vice versa – if ProTech were to vanish, a big manufacturer like PGT would still likely be there for parts. So having both be solid companies is like a double safety net.

So, my advice in line with what’s been said: pick a well-known window brand (PGT, Simonton, etc.) and a top-notch installer (like the sponsors being mentioned here). That way you’re covered either way.

On that note, good choice @ejackson55 leaning towards Karoly or ProTech. Both fit that description of solid installer using solid products.

I totally agree with everyone on choosing a good company. We actually went with ProTech Windoors for our window replacement last year, and even though they weren’t the very cheapest quote, we felt most comfortable with them. They offered a fair price, quality products, and their warranty was clearly explained (10-year labor, lifetime product through the manufacturer as mentioned). One thing that impressed me was that ProTech didn’t use any high-pressure tactics – no gimmicky discounts for “today only” or anything – just straight talk. That made me trust them more.
It’s been one year since our install with ProTech, and I’m happy to report everything is great. No issues at all, and the windows have made a noticeable difference in our home’s comfort. We haven’t had to call them for any fixes, but they did call us after installation to ensure we were satisfied and reminded us to register the product warranties. That kind of follow-up is reassuring.

I know you’re leaning towards Karoly, @ejackson55, which is awesome. I just wanted to share that even after the job is done, companies like these continue to take care of you. That, in my mind, is the real value of a good warranty – it’s the people behind it.

Sometimes paying a bit more upfront for a company that will stand by you is worth it. We feel it was worth it for us. 😊

Keep us posted on what you decide, and best of luck!

I’ve been quietly reading through this entire thread and just wanted to thank everyone. I’m in Brandon with a 2004-built home, about to start getting window replacement quotes. I was pretty clueless about warranties (and honestly might have just gone with the cheapest quote if not for reading this). Now I feel a lot more equipped to ask the right questions. I’ll make sure to grill each company on both their warranty and the manufacturer’s warranty, and get it all in writing.
This thread is like a masterclass for Tampa Bay window shoppers. Thanks @ejackson55 for starting it, and please do update us on how your project goes – it helps those of us coming right behind you!

Update: I just signed a contract with Karoly Windows & Doors! 🎉 After all the deliberation, I felt they offered the best combination of quality, warranty, and professionalism. The final deciding factors for me were:
Their 25-year installation warranty (that “Gold Standard” warranty) which is unbeatable. It just gives me huge peace of mind.

The window brand we’re getting is Simonton (StormBreaker Plus series, impact-rated). Simonton’s double-lifetime warranty on the product means we’re covered as long as we own the home, and it’s transferable if we sell. Karoly will handle the registration and all that, which is nice.

The price was actually very competitive. It wasn’t the lowest bid I got, but it was within a few hundred dollars of it. For the extra assurance I’m getting, I found that totally worth it.

Everyone I interacted with at Karoly (estimator, office staff) has been super responsive and patient with my many questions. No red flags at all.

Installation is scheduled a few weeks from now (they have to get the windows manufactured to custom sizes and pull permits, etc., so there’s a bit of lead time). They expect to do the install in one day since it’s not a huge house.

I really appreciate all of you sharing advice – it genuinely influenced my decision and gave me confidence. I’ll definitely come back with a post-installation update to let you know how it went and if everything’s as expected.

Now I’m just excited (and a little anxious, but mostly excited) to get the new windows in! 😃

@ejackson55 Congratulations on making a decision! I think you’ll be really happy with Karoly. It sounds like you did your homework and made an informed choice. The StormBreaker Plus are great impact windows too, by the way – good durability and energy performance.
Don’t be anxious, you’re in good hands. The lead time is normal; waiting is the hardest part now. Once they install, you’ll probably immediately notice how much quieter and cooler your house is (at least we did when ours were done).

Definitely let us know how the install goes. And kudos to you for taking warranty and quality seriously. Enjoy those soon-to-be new windows! 👏

Congrats @ejackson55! That’s great news. Karoly’s crew is known to be very efficient and detail-oriented. I had them on my shortlist too back when, and I’ve only heard positive things.
One piece of advice: once installed, take a few minutes with the lead installer to have them show you how to operate and clean the new windows (if they’re double-hungs, how to tilt them in, etc.) and also ask any maintenance questions you might have. They usually explain this anyway, but just in case. Also, double-check that you get all your paperwork – warranty info, permit approvals, etc. – before they leave or shortly after. It sounds like Karoly is organized about that, though.

Time to start dreaming of lower AC bills and a quieter home. 😊 Good luck on installation day!

I have a quick question on a related note: I’m comparing two quotes right now and the only big difference is one installer is using PGT windows and the other CWS (Custom Window Systems). They each claim their product’s warranty is “better.” PGT rep says their warranty is best in class, CWS guy says theirs is just as good if not better. From what @tea_steven shared, they seem pretty similar (lifetime for original, transferable once, etc.).
Can anyone confirm if there’s any real difference between PGT’s and CWS’s warranty? Both are impact windows. I’m inclined to think it’s a wash, and I should decide based on the installers (one offers 5-year labor, the other 7-year labor, so relatively close). Just don’t want to miss a detail if, say, one covers something the other doesn’t.

@writer78 I’ve looked at both PGT and CWS warranties in the past. They are indeed quite similar as you suspect. Both will cover defects in frame/materials for as long as you own the home. Both cover insulated glass seal failure for a lengthy period (I believe CWS might state 20 years on IGUs, PGT effectively does too for original owners). Both are transferable one time (often needing a form submitted within 30 days of sale or so). Neither covers labor after the first year. Neither covers things like acts of God, installation errors (that’s on the installer), etc.
If I recall, CWS’s warranty documentation had basically the same exclusions as most (no misuse, no tint film, no excessive settlement of building, etc.). PGT’s is more well-known just because PGT is a bigger company, but CWS has a good reputation in Florida as well and they’ve been around a long time.

I’d say you’re right – it’s a wash. Focus on which window product you prefer (some differences in look or performance maybe) and which installer you trust more (and slight edge to the 7-year labor vs 5-year, other things being equal).

I have PGT and I’m happy, but I know people with CWS who are also happy. Warranty-wise both should have you covered similarly if a defect arises.

@tea_steven Thanks for confirming. That helps a lot. I won’t sweat the minor differences then and will choose based on other factors. Much appreciated!

Did anyone have to register their warranty to be valid? I’ve heard some manufacturers require you to send in a registration card or do it online within a certain period after installation. My contractor said they’ll handle it, but I’m a bit paranoid and want to make sure it’s done. If I need to do it myself I will. How do you all handle warranty registration?

@ryanwhiskers230 Good question. Yes, most manufacturers these days have an online registration, which they prefer you do (sometimes it’s technically not mandatory for coverage, but it can be for full coverage or just to have your info in the system which makes any claims easier).
For example, Simonton, PGT, CWS, etc., all have an online form where you input your name, address, install date, contractor, etc., to register the products. Some installers will do this on your behalf (they have the info needed). It sounds like your contractor said they’ll handle it – many do as a courtesy. I would still ask for proof or confirmation. Like, “Once you register, will I get a confirmation email or copy of the registration?”

When I got my windows, the installer actually gave me a copy of the filled-out registration card they sent in, and I also got an email confirmation from the manufacturer (because I provided my email in the paperwork). If you don’t receive something, you can always call the manufacturer to verify if your address is registered, or just go online and submit a registration yourself to be safe. It usually doesn’t hurt to double-register (the system will just update/see it’s already registered).

Also, keep your contract and any receipt as proof of purchase/install date just in case, even if registered. And any warranty certificates or brochures that came with the windows – file them away.

Since your contractor seems on top of it, you’ll likely be fine. But a little follow-up for peace of mind doesn’t hurt. I’m the same way – rather double-check than assume.

@politics906 Thanks! I’ll definitely ask for that confirmation. I’m a bit OCD about paperwork, so I have a folder ready for all this. Appreciate the advice.

This might be slightly off-topic, but still about warranties – one company I talked to bragged about their “glass breakage warranty” which some of you have mentioned. They said if anything breaks the glass (storm, accident, etc.), they’d replace it free. Has anyone actually used such a warranty? It sounds almost too good to be true. Like, if a hurricane throws something through my window, would they really replace it free of charge? 🤷
I suspect there might be fine print (maybe excluding acts of God?), but the salesperson claimed it covered “any accidental breakage.” I’m thinking this is more of a marketing gimmick, but would love to hear if anyone has experience with it.

@jerrywriter248 That does sound like what Window World offers (and perhaps some others). In Window World’s case, yes, their standard window warranty includes accidental glass breakage for the original owner. I haven’t personally used it, since I didn’t end up going with them, but I have a neighbor who did. Funny enough, a year after her install, a stray golf ball (we live near a course) cracked one of her windows. She called up Window World, and they indeed replaced the sash with the broken glass at no cost. She just had to wait a couple weeks for the new sash to be ordered in. So it was legitimate – no deductible or anything.
Now, I’m not sure if “acts of God” like a hurricane are covered under that or if they’d call that a storm damage (which usually is insurance territory). The term “accidental” suggests unintentional breakage under normal circumstances. A hurricane might be considered something you have insurance for. It could vary. But for everyday accidents – kids, lawnmower throwing a rock, etc. – some warranties will cover it.

It’s definitely a nice perk. Just keep in mind it’s only as good as the company. If the company is known to honor it, then great. Window World is pretty huge, so they generally do honor it. Some local companies might also add a breakage guarantee as a selling point.

I wouldn’t choose a window solely for that feature, but it can tip the scales if you’re between two options equal otherwise. And of course, still carry insurance for the big stuff like hurricanes.

@food_diesel Thanks, that’s helpful. Good to know your neighbor had success with it. I guess it’s a real thing and not just smoke and mirrors. Still, like you said, not a primary deciding factor for me, but a nice bonus if included.

I actually opted for a package that had the glass breakage warranty (with a different local company in Tampa). Haven’t needed to use it yet (fingers crossed I won’t), but with two active kids playing sports in the yard, it gives a little extra peace of mind 😅. It wasn’t the main reason I chose that company, but it was a cherry on top.

Anyone encounter warranty clauses about maintenance? One of the quotes I got had a line like “homeowner responsible for annual maintenance of caulking and cleaning weep holes” and that the warranty wouldn’t cover leaks if maintenance wasn’t done. Is that normal? They basically said I should inspect caulk and re-caulk as needed after year 1. I get that caulk doesn’t last forever, but is it true that a window leak might not be covered if the caulking aged out?
I’m okay with doing upkeep; I just found it interesting they pointed that out. Maybe they were being extra upfront. Another company didn’t mention maintenance at all in their pitch.

@vr_bear Yes, many installers and manufacturers will note that routine maintenance (like caulking, keeping weep holes clear, lubricating moving parts) is the homeowner’s responsibility after a certain period. Caulking, in particular, is usually only warranted for maybe 1 year because it’s considered a wear item. So if 5 years down the line your caulk has cracked and a window leaks, that wouldn’t typically be covered as a “warranty issue” – it’s considered normal upkeep to re-caulk if needed.
It sounds like that company was just being very upfront about it, which honestly is good. A lot of people don’t realize they may need to re-caulk windows every so often (maybe every 5-10 years depending on the quality of caulk and weather exposure).

Similarly, clogged weep holes (the little drain holes in window frames) can cause water to back up. If that happens, a company could say that’s not a defect in the window, just needs cleaning.

So yes, it’s normal that those things aren’t covered by warranty (exclusions for lack of maintenance are standard). If you keep up with simple maintenance, you’ll be fine and your warranty stays valid. It’s actually a great question to ask installers, and it’s good that one gave you a clear answer.

I’d rather have a company spell out “you need to do X, Y, Z each year” than pretend their windows are magic maintenance-free forever.

TL;DR: It’s normal, just do the basic upkeep and you’re good. The warranty will cover defects, not neglect.
