- Had the same debate last fall. Measured everything twice, thought standard would work—nope, ended up trimming drywall and adding filler strips.
- Custom windows were pricier, but the install was way smoother on the next room.
- If you’re only swapping one and you’ve got patience, standard can work, but custom saved me a ton of hassle when I did the rest.
- Biggest surprise? The old framing was a mess. Found a random 2x4 just floating in there... houses are weird sometimes.
Had a similar situation when I redid the windows in my 70s split-level. Measured like five times, convinced myself standard would fit... ended up shaving down some framing and patching drywall anyway. Custom definitely cost more, but man, it made the second round so much easier. If you’re only swapping one, standard might be fine if you don’t mind extra work, but if your house is older or has settled weird, custom’s probably worth it. And yeah, I pulled out a whole handful of random shims and even a bottle cap from inside my wall—guess that was some builder’s lunch break...
Yeah, I ran into the same thing with my 60s ranch—measured a bunch, still ended up trimming the opening for a standard window. If you’re handy and patient, it’s doable, just expect some surprises. Custom is easier but definitely hits the wallet harder. Either way, it’s one of those jobs that feels good when you’re done.
That’s pretty much how it went for me too—measured three times, still ended up wrestling with the opening once the old window was out. I get why folks go custom, but man, those prices add up fast. Honestly, if you’re comfortable with a little trial and error, standard windows are fine. It’s more work than you first think, but seeing the finished job is worth the hassle. Just be ready for some weird surprises behind that old trim... I found a wasp nest in one of mine.
Funny you mention surprises—I pulled out a bathroom window last fall and found a bird’s nest wedged in the framing. Not sure who was more startled, me or the sparrow. I agree that standard windows are usually fine if you’re okay with a bit of fiddling. Measuring’s one thing, but nothing really prepares you for how out-of-square old houses can get. I ended up shimming way more than I expected, and had to sand down one side of the opening just to get the new window to sit flush.
Custom would’ve saved me some cursing, but I couldn’t justify the extra cost either. For me, it was worth the hassle, but I’d say if you’re not comfortable with a little improvising (and maybe some unexpected wildlife), it might get frustrating. Still, there’s something satisfying about seeing that new window in and knowing you did it yourself. Just keep a shop-vac handy for whatever falls out of those walls...
That’s spot on about old houses and nothing being square—mine’s from the 1920s and every window opening seems to tilt a different direction. I ran into the same shimming marathon, plus had to trim some of the old lath just to get the flange to sit right. Ever notice how sometimes you pull out a window and the framing’s barely hanging on? I always end up reinforcing at least one side.
Custom would be easier, but like you said, the price is wild. For me, the trickiest part was getting the flashing right after all that improvising. Curious if you used spray foam or backer rod around the gaps? I found low-expansion foam works, but you’ve gotta be careful not to bow the frame.
