Planning to replace windows myself—what should I remember?

Totally agree—seen plenty of newer homes with wonky framing myself. A few quick tips:
- Double-check measurements at multiple points (top, middle, bottom).
- Have shims handy... you'll probably need 'em.
- Don't assume openings are square—trust me, they're often not.

Good points overall, but I'd actually caution against relying too heavily on shims. They're handy for minor adjustments, sure, but if you find yourself needing a ton of them, it might be better to pause and re-check your framing. I've seen folks shim windows so much that it ends up causing issues later—like drafts or even leaks. Better to fix the framing itself upfront if it's really off... saves headaches down the line.

Hmm, fair enough, but isn't framing rarely perfect anyway? I mean, I've replaced a bunch of windows over the years, and even when I thought my framing was spot-on, I still ended up needing more shims than expected. Maybe it's just my luck—or lack of skill—but sometimes a little extra shim work beats tearing out half your wall to fix minor imperfections. Ever tried convincing yourself "it's just one shim" five times in a row...? Guilty here.

Haha, yeah, I've been there too. Honestly, how often is framing ever truly square and level anyway? Even when I measure three times, something always seems a hair off. I think it's more about adapting as you go—shims exist for a reason, right? Ever tried using those composite shims instead of wood? They don't compress or rot, and honestly, they've saved my sanity on a few window installs... might be worth checking out next time.

Composite shims sound like a great tip—I hadn't even thought about rot or compression issues with wood ones. I'm planning my first window replacement soon, and honestly, the uneven framing has me a bit nervous. Do you have any tips on how to tell when you've shimmed enough without overdoing it? I've heard too tight can cause issues down the line, but I'm not exactly sure how to gauge that sweet spot...

When you're shimming, try the "feel test"—basically, slide the shim in until you just feel resistance, but not so much that you're forcing it. You want support, not pressure. Can you still move it slightly with your fingers? That's usually a good sign. Also, check window operation as you go—open and close it gently to make sure nothing's binding or sticking. Even a slight tweak can make a difference. Uneven framing can be tricky, but patience pays off here...

That's a solid point about the feel test—I learned the hard way when I replaced my windows last summer. Thought tighter meant better insulation, but nope...ended up with windows that stuck slightly. Also, don't underestimate checking for drafts afterward; tiny gaps can really sneak up on you.

"Thought tighter meant better insulation, but nope...ended up with windows that stuck slightly."

Yeah, this is a common misconception—seen it happen more than once. The thing is, windows need room to expand and contract with temperature changes. If they're too snug going in, you'll definitely end up with sticking or even warping over time.

Another tip I'd add is to pay attention to the flashing and sealing around the frames when you're installing. Even tiny gaps can cause water damage down the road, and that's a headache you don't wanna deal with later. A good sealant (and proper application) makes a huge difference.

Curious though—did you use foam insulation around the frames or stick to traditional fiberglass batting? I've seen mixed results depending on climate and house structure...

Yeah, learned this the hard way myself. Couple things I'd add:

- Don't underestimate shims—proper shimming keeps windows square and prevents sticking.
- Foam insulation works great, but go easy...seen frames bow from overdoing it.

Good points. Also, don't skimp on flashing tape around the openings—I've seen moisture sneak in and cause rot later on. Learned that one myself after a rainy season...not fun to redo it.
