Sometimes you just gotta wrestle it into place... even if the house fights back.
That’s exactly how it felt when I tried to line up the sash weights in my front room window last month. It’s wild how something as basic as making sure things are plumb and square can turn into a full-body workout. I had this idea that a “close enough” fit would be fine, but seeing how drafty things get when there’s even a small gap really changed my mind.
I’ll admit, I underestimated how much those shims matter. I was so eager to get it done that I almost skipped a few steps, but then the window wouldn’t close right. Ended up pulling it out and re-shimming... twice. Not fun, but definitely worth it once I realized how much better it sealed.
It’s encouraging to hear someone else say patience pays off—even if it’s a pain in the moment. Makes me feel less like I’m just overthinking every step. These old houses really do have a way of keeping us on our toes.
You nailed it about shims making all the difference. I used to think they were just a formality, but after fighting with a crooked jamb for hours, I realized skipping those details just means double the work later. Funny how you start to notice every draft in an old house once you’ve fixed one window right. It’s definitely not overthinking—those little steps really do add up to a much better result. Old houses have a way of humbling you, but the payoff is worth it.
Funny how shims seem like overkill until you’re cursing at a window that just won’t sit right. I’ve tried to skip them “just this once”—never ends well. Ever tried those composite shims? They don’t split like the old cedar ones, but I swear they vanish when I need them. Old houses really do teach you patience, or maybe just stubbornness...
Isn’t it wild how something as tiny as a shim can make or break your whole afternoon? I’ve run into that too—skip a shim, and suddenly you’re fighting with the sash for hours. Composite shims are interesting. They’re definitely less fragile than cedar, but have you noticed they don’t compress quite the same way? Sometimes I miss the feel of wood, even if it splits now and then. Also, I swear they disappear into thin air the second you set them down—maybe it’s just my workbench eating them.
Old houses really do have their own rules. I’ve found myself getting way too creative with shimming in places where nothing is square. Ever tried doubling up on those plastic shims when the gap is huge? Not perfect, but sometimes it’s all you can do unless you want to rip out half the frame. I wonder if anyone’s found a “best of both worlds” shim yet...

I’ve wondered that too. I tried those composite shims once, but they just didn’t “give” the way cedar does. Ended up layering a wood one and a plastic one together—worked in a pinch, but probably not what the pros would recommend. Gaps in my 1920s place are all over the map, so sometimes it’s just whatever fits.

That’s basically the story of my house too—nothing is square, and I swear every window frame is a different size by at least a quarter inch. I tried those plastic shims once, but they felt like trying to wedge in a credit card. Cedar’s got that nice bit of squish, but then you get splinters or it splits if you look at it wrong.
I’ve actually used those paint stir sticks from the hardware store when I ran out of “real” shims. Not exactly pro-level, but hey, they’re flat and cheap. I’ve also stacked random bits of wood and plastic together like you did—kinda like shimming Jenga. It holds for now, but if a contractor ever opens up these frames, they’ll probably just shake their head and laugh.
Honestly, with these old houses, sometimes you just have to embrace the chaos and use whatever gets the job done.
That’s the spirit—sometimes “good enough” is exactly what these old places need. I’ve done the paint stick trick too and honestly, it works just as well as anything else most of the time. Have you ever tried those composite shims? I was skeptical, but they didn’t split like cedar. Still, nothing beats grabbing whatever scrap is lying around when you’re in the middle of a job and can’t make another trip to the store.
I actually tried composite shims for the first time last month when I was rehanging a door. They definitely hold up better than the cedar ones—no splitting, even when I got a little heavy-handed with the hammer. Only thing is, they’re a bit too flexible sometimes? Like, I had to stack a couple to get the right thickness, and it felt a little less solid than wood. Still beats driving back to the store for one missing shim, though. Funny how those random scraps end up being the MVPs mid-project...
I get what you’re saying about composite shims not splitting—I’ve had cedar ones snap on me more times than I can count, especially when I’m in a rush. But honestly, I still lean toward wood for anything that actually matters structurally. The flex in the composite ones just bugs me, especially if you’re dealing with old window frames that aren’t exactly square to begin with. Stacking them can get a little weird, and sometimes it feels like you’re just wedging in a piece of rubber that’ll shift over time.
I know it’s tempting to use whatever’s on hand (I’ve jammed paint stirrers and even bits of old flooring under things in a pinch), but for rehanging doors or leveling window sills, I trust wood more. At least if it compresses, it sort of “locks in” over time instead of bouncing back. Maybe I’m just set in my ways… but every time I try something new like composite, I end up second-guessing myself halfway through the job.
Curious if anyone’s actually had those flexible shims hold up long-term? Or do they eventually wiggle loose?
I’m right there with you—wood shims just “bite” into place in a way composites never seem to. I’ve used the plastic ones on a couple of jobs (mostly when I ran out of cedar), and they’re fine for quick fixes, but over time I’ve noticed they can shift, especially if the frame’s a little out of whack. One thing I do sometimes is use a wood shim for the main support and then a composite one behind it to fine-tune the angle. Not perfect, but it helps if you’re short on materials. For anything that’s got some weight or movement, though, I always go back to wood.
