I've had similar experiences with foam around my attic vents—worked great at first, but after a few seasons, it started cracking and letting drafts in again. Silicone definitely holds up better over time. Curious though, has anyone tried hybrid sealants? I've heard they're supposed to combine the insulation benefits of foam with silicone's flexibility, but haven't tested them myself yet...
Tried hybrid sealants last fall around my basement windows—honestly, wasn't super impressed. They seemed promising at first, but after a harsh winter, I noticed some shrinkage and tiny gaps forming again. Silicone still wins in my book...even if it's a pain to apply neatly, lol.

Yeah, silicone's messy, but honestly worth the hassle. I went through something similar last winter—tried one of those fancy new sealants because the guy at the hardware store swore by it. Looked great initially, but soon enough tiny drafts popped up again. Went back to silicone and haven't had an issue since. It's a pain, sure, but I'd rather deal with cleanup once than redo it every year.
I feel you on silicone being reliable, but man...the cleanup drives me nuts every single time. Last summer I got talked into trying this supposedly "easy-to-use" acrylic caulk by a friend who swore it was just as good. Looked neat, went on smooth, but come winter, the drafts snuck right back in. Ended up scraping it all out and redoing with silicone anyway. Lesson learned—if it ain't broke, don't fix it, even if it's messy as heck.

Yep, that's acrylic caulk for you—easy application but doesn't hold up well under temperature shifts or moisture. Silicone might be messy, but it's flexible and durable enough to handle seasonal expansion and contraction. Quick tip: masking tape along the edges before applying silicone makes cleanup way less of a headache. Learned that trick after too many afternoons scraping dried silicone off my hands...

I've had mixed luck with silicone myself. It definitely holds up better, but man, it's a pain to get right without making a mess. The masking tape trick helps, but I still end up smearing it sometimes... Any tips for smoothing it out evenly?
I've struggled with silicone sealant myself—it can be tricky stuff. I've heard about using a bit of soapy water on your finger or a smoothing tool to help glide over the silicone without it sticking as much. Tried it once and had decent results, but I still haven't perfected the technique. I'm curious though, does the type of silicone make a noticeable difference? I usually just grab whatever's labeled "window and door," but maybe there's a specific formulation or brand that's easier to work with or sets up better over time. Has anyone experimented with different types and noticed real-world differences in handling and durability?
I've definitely noticed differences between brands. Last summer I cheaped out on some generic silicone, and it was like trying to spread bubble gum—sticky mess everywhere. Switched to GE's stuff next time, way smoother and still holding up great a year later. Worth the extra few bucks imo.

Haha, been there myself... Did you try using a caulk smoothing tool or just your finger? I found that even the cheaper silicones can sometimes be manageable if you dip your finger in soapy water first. But yeah, GE silicone is definitely easier to work with overall. Glad it's holding up well for you—nothing beats a good seal that's still solid after a year or two.
I've had similar struggles with cheap silicone—sticky, messy, and frustrating. One thing that helped me was masking off both sides of the joint with painter's tape first. Lay down your bead, smooth it out (finger dipped in dish soap water works wonders), then peel the tape off immediately before it sets up. Makes even the cheap stuff look pretty decent.
But yeah, switching to GE silicone was a game changer for me too. Easier to apply, smoother finish, and way less cleanup afterward. Glad your windows turned out well...it's always satisfying when a DIY project actually holds up over time.
