"Good call on the rubber conditioner too—makes a noticeable difference, especially when the weatherstripping starts feeling brittle or cracked."
Yeah, rubber conditioner helps, but honestly if your seals are already cracking, might wanna think about replacing them soon. Conditioner buys you time, but won't fix deeper issues... learned that one the hard way.
Conditioner's good for upkeep, but honestly, if you're seeing cracks already it's probably past the point of no return. Better to swap them out now—saves headaches later when water starts sneaking in... trust me, been there.

I get where you're coming from, but I'm not totally convinced it's always a lost cause. When we moved into our first place, we had a couple windows that looked pretty rough—small cracks, peeling paint, the works. Instead of swapping them out immediately (budget was tight, you know how it is), we tried sealing them up with some silicone caulk and repainting the frames. Honestly, they've held up surprisingly well for the past two years. No leaks yet, fingers crossed...
Maybe it depends on how bad the cracks are or the climate you're dealing with? I think sometimes a little DIY maintenance can buy you more time than you'd expect, especially if you're not ready to drop serious cash on replacements just yet.
That's interesting, silicone caulk can definitely help seal things up temporarily. I've had mixed results myself—worked great on smaller cracks, but bigger ones just kept coming back after a season or two. Makes me wonder if there's a specific type or brand of caulk that's better suited for window frames... anyone experimented with different products and noticed a real difference in durability?
I've noticed the same thing—silicone caulk seems great at first, but it doesn't always hold up long-term, especially with bigger gaps. I've heard polyurethane-based sealants might be tougher... might be worth checking out if durability's your main concern.
I've tried polyurethane sealants myself, and yeah, they definitely have their strengths. But are you dealing with a lot of movement or temperature swings around your windows? Polyurethane tends to stay flexible longer, which helps if things expand or contract regularly. On the downside, I've found it's a little trickier to apply neatly compared to silicone—can be messy if you're not careful.
Have you also looked into backer rods for filling those bigger gaps before sealing? I started using them a few years back, and they made a noticeable difference. They help the sealant bond better and prevent it from sagging into wider gaps. Might be worth giving that a shot if durability is your main goal.
Also, how old are your windows? Sometimes the seals fail because the frames themselves are shifting or deteriorating... if that's the case, no caulk or sealant will completely solve the issue long-term.
Polyurethane definitely has its perks, but honestly, I've had better luck with high-quality silicone sealants, especially around windows. A few years back, I was working on an older house that had some serious temperature swings—hot summers, freezing winters—and the polyurethane just didn't hold up as well as I'd hoped. It stayed flexible, sure, but it seemed to degrade faster under intense UV exposure. Switched to a UV-resistant silicone, and it held up noticeably better over time.
Backer rods are a great tip though, totally agree there. They saved me from wasting a ton of sealant on wider gaps. But one thing I'd add is to check your window drainage too. I once had a client whose windows kept failing prematurely, and turns out the weep holes were clogged, trapping water inside the frames. Cleared those out and suddenly the sealants lasted way longer... sometimes it's the little things that make the biggest difference.
Good point about silicone holding up better under UV. I've noticed similar results, especially on south-facing windows that get hammered by sunlight all day. Another thing I've found helpful is making sure the window frames themselves are properly primed and painted—sounds basic, but you'd be surprised how often people skip or rush that step. Had a job once where the homeowner complained about sealants constantly failing, turned out the wood underneath was absorbing moisture because of poor paint prep... fixed that, and suddenly everything lasted way longer.
Definitely agree on the paint prep—seen that issue way too often. Another thing I've noticed is people underestimate the importance of regular cleaning. Dust and grime build-up can trap moisture, speeding up deterioration. Had a client once who couldn't figure out why their windows were aging so fast, even though they'd done everything else right. Turned out they hadn't cleaned the frames or sills in years... dirt was holding moisture against the wood and sealant, causing premature rot. Quick scrub-down every few months made a huge difference. Also, checking drainage holes regularly helps—if they're clogged, water sits longer and causes trouble. Simple stuff, but it adds up over time.

Good point about regular cleaning—I've seen similar issues myself. However, one thing I'm curious about is the role of window treatments like blinds or curtains. I've noticed that windows behind heavy curtains or blinds seem to age differently compared to those left exposed. Could it be related to airflow or sunlight exposure? I had a set of windows in my living room that were always covered by thick drapes, and they seemed to develop condensation more frequently, especially in colder months. Eventually, I switched to lighter curtains and made sure to open them regularly, and the condensation issue noticeably improved.
Has anyone else experienced something similar or looked into how window coverings might affect window longevity? It seems logical that airflow and sunlight exposure could play a role, but I'm not entirely sure how significant it is compared to cleaning and drainage maintenance.
