Tough weather and windows: paint or aluminum cladding?

Honestly, I get where you’re coming from. I’ve got a 1950s place with original wood windows, and every couple of years I debate this exact thing. The look of wood is hard to beat—there’s something about the character you just don’t get with aluminum. But man, the upkeep... especially after a few nasty winters. I tried high-end exterior paint two summers ago, took my time sanding and priming, and it looked great for a while. By the end of the second winter though, some spots were already peeling where snow piled up against the sills.

The cladding idea is tempting since it’s basically “set it and forget it,” but then you lose that natural look unless you go with one of those faux-wood finishes (which always seem a little off to me). Have you checked what cladding would run for your windows? When I priced it out, the upfront cost was pretty steep compared to paint, but factoring in labor and time... might even out over a decade or so.

I’m curious—do your windows have any rot or damage yet, or are they still solid? That made my decision harder because mine had a couple soft spots that needed patching anyway. Also, how much sun do your windows get? My south-facing ones take way more abuse than the others.

Just wondering if anyone’s found a happy medium—like painting but adding storm windows or something to cut down on direct exposure.

The struggle is real—original wood looks awesome but it’s a constant battle with the elements. I’ve seen people try storm windows over painted sashes, and it does help some with both drafts and paint longevity. Thing is, storms can make cleaning a pain, and they don’t always blend in on older homes. Have you looked into those new composite storms that are less clunky? Just curious if anyone’s had luck with those or if it’s just another maintenance headache down the line.

I know the appeal of storms, and the new composites do look better than the old chunky aluminum ones, but honestly, I’ve found them to be more trouble than they’re worth. I put a set on our 1920s bungalow three years back—figured it’d be a good middle ground to keep the original sashes but cut down on drafts. They definitely helped with insulation, but cleaning got annoying fast. The clips and tracks gummed up with dust, and you still have to take them down if you want to really clean both sides of the glass. Not impossible, just tedious.

One thing I’d suggest—have you actually tried a high-quality paint job with modern primers on your sashes? I know it sounds old school, but if you do the prep right (full scrape, sand, oil-based primer, then two coats of exterior latex), you can get five, even ten years out of a paint job before it really starts to peel. I’ve done it both ways: storms over painted wood, and just well-prepped painted sashes. The storms helped a little, but honestly, the prep work made more difference in how long the paint lasted. The storms mostly cut drafts and noise, but didn’t save me from repainting eventually.

Aluminum cladding is tempting because it’s “set it and forget it,” but it definitely changes the look. I tried cladding on my garage windows as a test run—looks fine from a distance, but up close, it’s a little too modern for my taste against the old woodwork. Plus, if water gets behind the cladding, you might not notice rot until it’s a big problem.

If you’re set on keeping the original look and don’t mind a bit of elbow grease every few years, I’d lean toward just doing a solid paint job and maybe some weatherstripping. Storms (composite or otherwise) are a compromise, but they’re not maintenance-free either. Kind of feels like trading one chore for another sometimes.

Funny, I was just staring at my own windows this morning, wondering if I should keep babying them or just go full cyborg with cladding. I totally get what you mean about the storms and the cleaning hassle. My parents had those, and every spring was like a mini Olympic event getting them off and back on. I’ve tried the “proper” painting routine—scrape, sand, primer, the whole nine yards. It lasts longer than I expected, but I still end up with a few mystery chips after a winter or two. Maybe it’s my technique… or just the squirrel that likes to perch on the sill.

Cladding does have that “I’m done thinking about this” vibe, but I’m not wild about the slightly tin-can look either. Plus, I keep hearing horror stories about hidden rot. For now, I’m leaning toward another round with the paintbrush and some heavy-duty weatherstripping. At least that way, if it goes wrong, I can blame my own handiwork instead of a contractor.

I hear you on the “tin-can” vibe with aluminum cladding—it’s not for everyone, and yeah, hidden rot is a real thing if the prep isn’t spot-on. Honestly, painting’s more work but at least you know what’s under there. I’ve seen some folks use a hybrid approach: paint the main frame but add aluminum drip caps or sill covers where water really sits. That way you get a bit of protection without going full robot. And squirrels…they’re ruthless.

That’s actually my go-to move lately. Full cladding looks sharp at first but, man, if water sneaks behind, you’re in for a nasty surprise. I always tell people: prime those sills like your sanity depends on it, then slap on some aluminum just where the rain likes to hang out. Keeps things tidy and you can still spot trouble early. Squirrels, though—still haven’t found anything they won’t chew through.

I get the logic behind just cladding the trouble spots, but isn’t there a risk that you’re missing hidden rot in the painted parts? I’ve had painted sills look fine for years, then suddenly I’m poking a screwdriver through mushy wood. I guess I’m more paranoid about water finding its way in somewhere unexpected—especially with old windows where nothing’s quite square anymore.

Have you ever tried the newer composite sills or those PVC covers? I’m wondering if they’d hold up better long-term, or if they just bring their own set of headaches. I do like being able to see what’s going on under the paint, but sometimes I feel like I’m chasing my tail with touch-ups every spring. And yeah, squirrels... I swear they could chew through steel if they wanted.

I’ve had the same thing happen—thought a sill was solid, then one spring I found rot under what looked like perfectly good paint. The worst part is when the wood’s gone soft behind the paint and you only realize it after water’s already done its damage. I’ve tried those PVC sill covers on two windows (north side, gets hammered by wind and rain) and they’re holding up better than painted wood so far. But they’re not a magic bullet. If there’s already moisture trapped underneath before you install them, it just sits there and the wood keeps rotting out of sight.

One thing that annoyed me: the PVC expands and contracts a bit with temperature swings, so you have to be careful about sealing the edges or you’ll get gaps over time. And if you ever want to repaint or fix anything underneath, you’re basically ripping the cover off and starting over.

I haven’t tried composite sills yet, but I’m tempted. My neighbor swapped his old ones for composite last year and hasn’t complained—though, to be fair, he’s not as picky about details as I am. And yeah, squirrels... I watched one gnaw through a plastic vent cover like it was nothing.

That’s interesting about the PVC covers—I've installed a few for folks who were tired of repainting every couple years, but I always wonder about what’s going on underneath. Did you check for moisture before putting them on, or just hope for the best? I’ve seen some sills look fine on the outside, but when you poke at them with a screwdriver… mush city.

The expansion thing is a pain too. Ever notice if the caulk pulls away in winter? I’ve had callbacks where folks thought they had leaks, but it was just a tiny gap from the PVC shifting.

Curious if anyone’s tried aluminum cladding over wood. It’s supposed to breathe a bit more than PVC, but I’m skeptical—does it actually let moisture escape, or are we just trapping problems again? And composite sills—are they as tough as advertised? I like the idea, but haven’t seen enough long-term installs to trust ‘em completely. Squirrels, though... not sure anything short of steel is going to stop those little vandals.
