Good to hear they're holding up well. I've installed plenty of Andersen 100s, and most homeowners seem pretty satisfied long-term. Curious though, anyone here have experience with Pella 250s past the five-year mark? I've heard mixed things—some say they're solid, others mention seal issues after a few seasons. Wondering if that's more climate-related or just luck of the draw...
I've had Pella 250s installed for about six years now, and while they're decent overall, I've noticed some minor seal deterioration on a couple windows facing direct afternoon sun. Could be climate-related—I'm in a region with pretty intense summers—but honestly, it makes me question their long-term durability. Andersen 100s seem to have a slightly better track record in my experience, especially regarding consistent energy performance over time. Just my two cents though...
"I've noticed some minor seal deterioration on a couple windows facing direct afternoon sun."
Yeah, direct sunlight can really do a number on window seals, especially in hotter climates. Had a similar issue with my old Pellas after about five years—ended up resealing them myself, wasn't too tough and held up pretty well afterward. Andersen 100s might be a bit better long-term, but honestly, regular maintenance and checking seals every couple years goes a long way, regardless of brand. Just something to keep in mind...
I've had Andersen 100s for about 4 years now, and honestly haven't noticed any seal issues yet, even on the west-facing side that gets blasted by afternoon sun. Maybe I'm just lucky? But yeah, sunlight can be brutal on seals. Did you use a specific sealant when you resealed yours, or just standard silicone? I'm thinking I should probably check mine soon...
"Did you use a specific sealant when you resealed yours, or just standard silicone?"
I've resealed a few Andersen 100s myself, and from experience, I'd recommend steering clear of standard silicone. While silicone is generally versatile, it doesn't always hold up well under prolonged UV exposure—especially on west-facing windows that get hammered by afternoon sun. Instead, I've had better luck using a high-quality polyurethane-based sealant specifically rated for exterior window applications. Brands like OSI Quad or Sikaflex have worked reliably for me in the past.
Also, even if you haven't noticed any issues yet, it's smart to do periodic inspections. Sometimes the seals can degrade subtly without obvious signs until moisture intrusion becomes noticeable. A quick visual check and gently pressing around the edges every year or two can save you headaches down the road. Better safe than sorry...
"Instead, I've had better luck using a high-quality polyurethane-based sealant specifically rated for exterior window applications."
Good call on the polyurethane-based sealants. I learned the hard way that regular silicone just doesn't cut it long-term—ended up redoing mine after only two years. OSI Quad has been solid for me too. Just make sure you prep the surface well beforehand; clean thoroughly and remove any old residue. Makes a huge difference in how well it adheres and lasts over time...

I've had decent luck with OSI Quad too, but honestly, prep work matters more than brand. Learned that lesson after rushing through a window job once... ended up peeling off in spots within a year. Take your time, clean thoroughly, and it'll hold up fine.
I've gotta agree that prep work is crucial, but I'm not entirely sold on the idea that brand doesn't matter as much. I've seen some pretty meticulous installs fail prematurely because the sealant itself just wasn't up to snuff. Sure, OSI Quad has a solid rep, but I've personally had even better results with Sashco's Big Stretch. It stays flexible through temperature swings, and I've seen it hold tight for years without cracking or peeling—even in spots where the prep wasn't exactly textbook-perfect (guilty as charged here...).
I remember helping a buddy redo his windows a few summers back. We were rushing, trying to beat a storm rolling in, and honestly, we cut corners on the cleaning and prep. I figured we'd be redoing everything within a year, tops. But surprisingly, the Big Stretch held strong—no peeling, no gaps, nothing. That experience convinced me that while prep is definitely important (no argument there), picking a quality sealant can sometimes save you from your own mistakes.
Also, since we're talking Andersen 100 vs. Pella 250 here, I'd say the sealant choice becomes even more critical if you're going budget-friendly. With more affordable windows, you might not get all the bells and whistles of premium models—especially when it comes to weather resistance and durability. Investing in a higher-quality sealant can help bridge that gap and ensure you're not redoing your work sooner than you'd like.
Just my two cents based on what I've seen firsthand... everyone's mileage varies, of course.
Interesting take, and I get where you're coming from with the sealant choice being a big factor. But honestly, I'm still not convinced that even the best sealant can consistently bail you out if prep isn't done right. I've seen Big Stretch perform well too, but I've also witnessed it fail pretty miserably when the surface wasn't properly cleaned or primed.
Here's the thing: sealants like Big Stretch or OSI Quad are formulated to bond best on clean, stable surfaces. If there's dust, oils, or old residue, you're rolling the dice no matter how top-shelf your caulk is. Sure, you got lucky that one time rushing through your buddy's windows, but that's more exception than rule in my experience.
If you're on a budget and choosing between Andersen 100 and Pella 250, I'd double down on prep rather than relying solely on premium sealants. Scrub those surfaces thoroughly, use a quality primer if needed, and apply the caulk carefully in consistent beads. A little extra effort upfront usually pays off more reliably than hoping your sealant can cover for rushed prep work... just my experience though.
Gotta say, I mostly agree with your points on prep being crucial—no argument there. But I'll toss in a slightly different perspective based on my own experiences. I've done a bunch of window installs over the years, and while prep is definitely king, I've also seen some premium sealants save the day even when prep wasn't exactly textbook perfect.
Case in point: I did a job a couple years back where the homeowner had already "prepped" the openings himself before I got there (you know how those DIYers can be—good intentions, questionable execution). Anyway, surfaces weren't exactly spotless, and I was tight on time. I used OSI Quad, figuring it was my best shot at avoiding callbacks. Fast forward two years, and those windows are still sealed tight, no leaks, drafts, or callbacks. Not saying that's the smart way to do things, but sometimes a really good sealant can bail you out of a jam.
Now, don't get me wrong—I'm not advocating skipping proper prep. You're right, it's always better to do it right from the start. But realistically, sometimes you're dealing with less-than-ideal conditions, and that's when investing in a higher-quality sealant can actually pay off. It's like insurance: you hope you don't need it, but you're glad it's there when things don't go according to plan.
As for Andersen 100 vs. Pella 250, honestly, both are solid budget-friendly choices. I've installed both, and I think the differences are pretty minimal for most homeowners. I'd probably lean Andersen personally, but that's just because I've had fewer headaches with their customer service. But whichever you pick, just remember—prep well, and keep a tube of the good stuff handy just in case Murphy's Law kicks in...which, in my experience, it usually does.
