One thing that’s helped me—after dealing with a couple busted window latches—is giving them a tiny squirt of silicone spray every spring. Seems to keep them from sticking or corroding, at least in my drafty old place. Anyone else got tricks for hardware that actually holds up?
Silicone spray definitely helps, but I’ve noticed it can attract a bit of grime over time—especially if you live somewhere dusty like I do. I tried switching to graphite powder for one set of windows, just to see if it’d keep things cleaner. It works, but it’s kind of messy and gets everywhere if you’re not careful. Has anyone actually found a lube that doesn’t either gum up or leave black streaks? Also, curious if anyone’s tried swapping out the old brass latches for newer stainless ones. I’ve thought about it, but I’m not sure if it’s worth the hassle or if it’d even fit my old wood sashes. Sometimes I wonder if it’s just better to keep fixing the originals instead of trying to retrofit everything…
- Totally get what you mean about the grime.
I sprayed mine last spring and by July it looked like I’d smeared a donut on the sash.“Silicone spray definitely helps, but I’ve noticed it can attract a bit of grime over time—especially if you live somewhere dusty like I do.”
- Tried graphite too, but my dog tracked it across the floor. Not my best move.
- Haven’t found a magic non-gunky lube. WD-40 Specialist Dry Lube worked okay, but it smells weird and didn’t last long.
- On swapping latches: I measured my old brass ones (house from the 50s) and the screw holes didn’t line up with the new stainless ones at the hardware store. Didn’t feel like filling and redrilling, so I just cleaned and reinstalled. They’re still a little wonky but… character?
- Anyone else have windows where the wood swells up and the lock barely lines up half the year? Wondering if that’s just my place or if it’s an old house thing.
That swelling wood thing is classic old house behavior—mine’s from ’49 and every humid summer the sash gets just misaligned enough to make locking a mini workout. I tried planing a hair off one window but then winter hit and there was a draft, so… lesson learned. As for lube, I keep circling back to just a bar of plain paraffin wax. Not perfect, but at least it doesn’t turn into sludge or get tracked around by pets. Kind of wild how nothing out there is really “set it and forget it.”
I’ve run into that same “Goldilocks zone” with planing old sashes—take off too much and you’re stuck with drafts, leave it alone and you’re wrestling the thing shut every August. I’ve found that sometimes less is more: instead of shaving down the wood, I’ll just tighten up the screws on the lock hardware or swap out the old, bent ones for slightly longer ones. It’s surprising how much slop comes from loose fasteners, especially after decades of swelling and shrinking.
Paraffin wax is a solid move—my grandfather swore by it for everything from drawers to windows. The only hitch I’ve had is if it gets warm and dusty, it can gunk up in the corners. Silicone spray’s been my go-to because it doesn’t seem to attract as much grit, but yeah, it’s not totally “set it and forget it.” I tell folks to avoid WD-40 on window hardware since it can gum up over time—learned that one the hard way.
If you’re dealing with really stubborn locks, sometimes just backing out the latch plate and slipping a thin shim behind it gets things lined up again without having to mess with the sash itself. Not the prettiest fix, but it gets you through another season.
Funny how with all the tech out there, we’re still fussing with wax and shims. Maybe that’s half the charm—or at least a good excuse to take a break and complain about old houses.
You nailed it with the shim trick—sometimes ugly fixes are the only thing standing between you and a stuck window in July. I’ve tried the paraffin too, but honestly, I’m with you on the silicone spray for less mess. Funny how a five-minute tweak can buy you another year of peace.
Title: Making window locks last longer: my quick fix
I’ve definitely been in the “ugly fix” camp a few times—one of my kitchen windows still has a bit of cardboard wedged in the latch from last summer. Not pretty, but it does the job, and honestly, nobody notices unless they’re looking for it. I used to mess with candle wax, but it always got everywhere and left this weird residue on the paint. Plus, the smell stuck around for days, which wasn’t great in July heat.
Silicone spray has been my go-to lately, too. Here’s my step-by-step for anyone curious: I just open the window, wipe down the tracks with a rag (old T-shirt works), and hit the moving parts with a quick squirt of silicone. I learned the hard way to put down some paper towels first—the overspray can get slick on the sill. Then I work the window up and down a few times to spread it out. Takes maybe five minutes, tops, and I don’t have to fight with the lock every time I want some air.
One thing I noticed, though—on my older wood windows, sometimes the silicone makes the lock stick a little at first. Not sure if it’s just my house or what. Usually sorts itself out after a couple days, but it’s kind of annoying in the meantime.
Anyway, I’m all for fixes that buy me another year or two before I have to actually replace anything. My house is 70+ years old, so if I stopped to do everything “properly,” I’d never be done. Sometimes good enough really is good enough... especially when it means not sweating through another stuck window in July.
Cardboard in the latch—been there. I’ve got a window propped open with a chopstick from takeout night, and honestly, it’s holding up better than some of the “real” fixes I’ve tried. I do like silicone spray, but I get what you mean about the old wood windows acting up. Mine sometimes get a little gummy, like they’re mad at me for not doing things the “proper” way. At this point, if it opens and closes without a crowbar, I call it a win. Sometimes ugly fixes are just the most honest ones.
That chopstick story hits home—I've seen folks use everything from paint stirrers to butter knives to keep stubborn windows in line. Honestly, sometimes those “temporary” fixes outlast the hardware you paid for. I do wonder, though: have you ever tried sanding down the sides of the sash a bit? I’ve found a little elbow grease can make those gummy old windows slide like new, or at least cut down on the wrestling match. Curious if anyone’s had luck with that, or if it just made things worse?
- Used to think sanding was the magic fix, but it’s been hit or miss for me.

“I’ve found a little elbow grease can make those gummy old windows slide like new, or at least cut down on the wrestling match.”
Tried this on one window—helped at first, but after a month, the sash started sticking again. Maybe my old wood windows just swell too much with humidity?
- Sometimes I wonder if sanding too much is risky. I once went a bit overboard, and the window got drafty. Ended up stuffing a towel in the gap during winter... not my finest moment.
- Been using a bit of candle wax along the track lately. Seems to work better than sanding, at least for my place.
- Curious if anyone’s found a long-term fix that doesn’t involve replacing the window entirely. Temporary hacks are great, but I’d love something that actually lasts.
