Totally agree silicone spray is the way to go, especially compared to talcum powder. Another thing I've found helpful is giving the window seals a quick clean with mild soap and water before applying anything. Dirt and grime buildup can really speed up aging, so starting with a clean surface makes a noticeable difference. Learned that one after seeing my windows dry out faster than expected... live and learn, right?
Silicone spray definitely helps, but honestly, I've found that just keeping an eye on the weatherstripping and seals regularly makes a huge difference. I used to wait until things looked obviously worn out before doing anything, but now I try to check them every few months or so. If you catch small cracks or drying early, you can usually prevent bigger issues down the line.
Also, totally agree about cleaning first—soap and water is great. But one thing I'd add is to make sure you're drying everything thoroughly afterward. I learned this the hard way after cleaning my window seals one afternoon and leaving them damp overnight. Next morning, they were still wet in spots, and it seemed like dirt stuck even worse after that. Now I always wipe them down with a dry cloth or paper towel right after washing.
Another thing I've noticed over the years is that direct sunlight really speeds up aging on rubber seals. On windows that get full sun exposure most of the day, I've started using a UV protectant spray (the kind you'd use on car dashboards). It seems to help slow down cracking and fading quite a bit. Not sure if anyone else has tried this, but it's been working pretty well for me so far.
I guess it's all about staying ahead of things rather than waiting until they're already damaged. Learned that lesson more times than I'd like to admit...
"Another thing I've noticed over the years is that direct sunlight really speeds up aging on rubber seals."
Yeah, sunlight is definitely a killer for window seals. I've noticed the same thing at my place—windows facing south seem to age twice as fast as the ones on the shady side of the house. I haven't tried the UV protectant spray yet, but now I'm curious if it makes a noticeable difference long-term.
One other thing I've found helpful is checking the drainage holes at the bottom of the window frames. They can get clogged with dirt or debris pretty easily, and when water can't drain properly, it sits there and eventually damages the seals. Learned this after a heavy rainstorm left water pooled up inside the frame... not fun. Now I just poke around with a toothpick or something every few months to keep them clear.
Also, has anyone else noticed certain brands of silicone spray working better than others? I've tried a couple different ones, and some seem to attract dust more quickly, which kinda defeats the purpose. Just wondering if it's just me or if there's actually a difference between brands.
"One other thing I've found helpful is checking the drainage holes at the bottom of the window frames."
Good call on the drainage holes—I overlooked mine for years until I had a similar issue with water pooling after storms. Another thing I've noticed is that cheaper silicone sprays tend to leave a sticky residue, attracting dust and grime. Switched to a slightly pricier brand last year, and it's been noticeably cleaner. Sometimes spending a bit more upfront saves headaches down the road...
Yeah, good point about the silicone sprays. I used a cheap one once and regretted it—ended up with gunk all over the tracks. Now I just wipe down the frames with a damp cloth every couple months and use a better-quality spray maybe twice a year. Seems to do the trick without much hassle...
"Now I just wipe down the frames with a damp cloth every couple months and use a better-quality spray maybe twice a year."
That's pretty much what I'd recommend too. Cheap sprays often cause more problems than they solve. One thing I'd add—check your window seals occasionally. I've seen decent windows age prematurely because folks overlook cracked or worn seals letting moisture in. Curious, does anyone here regularly inspect or replace their seals, or do you mostly wait until there's an obvious issue...?
One thing I'd add—check your window seals occasionally.
I agree about checking seals occasionally—it's easy to overlook. I usually just give them a quick glance when wiping frames, but honestly... I don't replace them unless they're clearly cracked or peeling. Maybe I should be more proactive?
"I usually just give them a quick glance when wiping frames, but honestly... I don't replace them unless they're clearly cracked or peeling."
That's fair enough, but honestly, I think some folks make too much fuss about seals. I've seen windows in houses built decades ago that still have their original seals, and they're holding up fine. Unless you're noticing drafts, moisture buildup, or actual damage, replacing them proactively might not be worth the hassle or cost.
I've found that paying attention to other factors—like keeping the frames clean and ensuring good drainage around the window sills—does way more to extend window life than obsessing over seals. A few years back, I had a neighbor who replaced all his window seals every couple years religiously, and guess what? His windows didn't last noticeably longer than mine, and I barely touched mine for years. Go figure.
Not saying you shouldn't check them at all—obviously it makes sense to replace something clearly damaged—but being overly proactive might be unnecessary. Just my two cents.
I agree, people definitely overthink seals sometimes. I've lived in my current place for nearly 15 years now, and the windows were already a good decade old when we moved in. Honestly, I've only replaced seals once or twice when they were visibly cracked or letting moisture in. Like you said:
"Unless you're noticing drafts, moisture buildup, or actual damage, replacing them proactively might not be worth the hassle or cost."
Regular cleaning and making sure water doesn't pool around the frames has done way more to keep mine in decent shape.
Totally agree with your point about regular cleaning—it's underrated. I've also found that occasionally lubricating the hinges and hardware helps prevent sticking or warping, especially in humid climates. Small maintenance steps like these can really extend window lifespan without much effort or cost.
