Just got new windows installed about two months ago, and now I'm noticing these thin little cracks popping up out of nowhere. At first I thought maybe something hit them, but they're on the inside pane and there's no sign of impact. Installer says it's probably "stress cracks" from settling or temperature changes or whatever. Um, is this normal for brand-new windows? Feels kinda sketchy to me... anyone else dealt with this or have advice?
Yeah, that does sound a bit off to me too. I've had new windows installed twice now (different houses), and honestly, never saw cracks popping up like that. Stress cracks can happen, sure, but usually they're pretty rare and more common with older windows or extreme temperature swings. Two months in seems way too soon for that kind of issue.
One thing I'd check is whether the installer used shims properly or if the frames were forced into place. If the window frames are under tension because of improper installation, that could definitely cause stress cracks. Also, double-check your warranty paperwork—most reputable window companies cover stress cracks within the first year or so.
I'd probably push back a bit on the installer and ask them to come out and inspect again. Maybe even get a second opinion from another contractor if you can swing it. Better safe than sorry, especially since windows aren't exactly cheap...
I've seen this happen a couple times, and honestly, it's usually down to installation issues rather than the windows themselves. Even high-quality windows can crack if the frames aren't squared up properly or if they're jammed into openings that aren't quite right.
If you're comfortable doing a quick check yourself, grab a level and see if the frames are sitting straight and true. Look closely around the edges—if you notice uneven gaps or spots where the caulking looks stretched or compressed, that's a sign something's off. Also, gently press around the frame edges; if there's noticeable flex or movement, that's another red flag.
Definitely worth getting the installer back out to take a look, but I'd also snap some clear photos of the cracks and framing issues first. Having visual proof can help if things get tricky with warranty claims or disputes. And yeah, a second opinion never hurts—especially if the original installer seems hesitant or dismissive.
