I hear you on the ocean air—nothing really lasts forever out here. I actually tried composite sills a while back, thinking they’d be low-maintenance, but they started swelling and looking rough after a couple years. Ended up switching to aluminum too. Not perfect, but at least it doesn’t crack or warp as fast. Seems like it’s just about picking your battles with coastal weather.

That’s the truth. I moved into my place right before hurricane season (rookie mistake) and I swear, the first time it rained sideways, I found a puddle INSIDE my window frame. I had these old wooden sills that looked pretty in the realtor photos but were basically sponges in disguise. My neighbor joked that I should just plant some moss and call it a terrarium.
I looked into composite, too, after reading all the “maintenance-free” hype, but after seeing what happened to the ones on my friend’s porch (they bubbled up and got weirdly soft?), I chickened out. Aluminum seemed kind of industrial to me at first, but I went for it anyway. It’s not winning any beauty contests, but at least I’m not scraping paint flakes off every spring. It does get a little chalky in spots, though, and the salt air still finds a way to make everything look a bit tired after a while.
Honestly, I’ve started thinking of it like a coastal badge of honor—if it’s not a little weather-beaten, are you really living by the ocean? I do miss the old wood look sometimes, but not enough to go back to wrangling with rot and repainting every year. I guess I’m just learning to embrace the “perfectly imperfect” vibe out here.
Funny thing, I’ve actually had better luck with composite than aluminum, but I think it really comes down to the brand and how it’s installed. Seen a lot of bubbling when folks skip the flashing or use the wrong sealant. Wood’s got that classic charm, but unless you’re up for yearly touch-ups, it’s a losing battle near salt air. Aluminum’s low-maintenance, sure, but I get what you mean about the look—it can feel a bit cold. Sometimes I wonder if fiberglass is worth the extra upfront cost... it holds paint well and shrugs off moisture, but not everyone wants to shell out for it.
That’s interesting—you mentioned,
I’ve wondered about that myself. Is it mostly the flashing and sealant that make or break things, or does the installer’s experience matter more? I’ve seen a neighbor’s composite sills bubble up after just two years, but mine (different brand) are still fine. Maybe it’s luck... or maybe just better prep.“it really comes down to the brand and how it’s installed.”
Fiberglass is tempting, but like you said, the price tag can sting. Does it actually last so much longer that it pays off in the end? Or do you just end up repainting less often? Always feels like there’s a catch with these upgrades.
- Totally get what you mean about the prep making a difference. When I swapped out my old wood sills for composite, the installer spent extra time on the flashing and caulking—still holding up after four years, no bubbling or leaks.

Honestly, I think both matter, but a careful installer who doesn’t cut corners is huge.“is it mostly the flashing and sealant that make or break things, or does the installer’s experience matter more?”
- Tried fiberglass for a basement window—pricey, but barely needs touch-up. Paint still looks fresh after three winters. If you hate repainting, it might actually save some headaches... just wish it was less expensive upfront.
“is it mostly the flashing and sealant that make or break things, or does the installer’s experience matter more?”
I’ve seen both sides of this. Even top-notch flashing and caulk can fail if the installer rushes or skips steps. For my coastal place, I actually watched the crew layer up sill pan flashing, then back-caulk before setting the window—no gaps anywhere. That’s held up way better than a neighbor’s “pro” job where they just slopped on sealant and called it a day. Materials help, but methodical prep and install are what really keep the water out. Fiberglass is solid, but yeah... that price tag stings.
I hear you on the install making all the difference. When I bought my place, I thought just using good sealant was enough... but after one nasty winter, I found out the hard way that a sloppy install can undo even the best products. Had to redo a couple sills myself—definitely learned to watch how careful folks are with prep and layering. Materials matter, but if the crew’s just rushing, you’re gonna end up with leaks no matter what.
Couldn’t agree more—prep work is everything. I’ve seen high-end caulk and flashing go to waste because someone skipped cleaning the sill or rushed the first bead. Doesn’t matter how fancy the materials are if there’s a gap or poor overlap. I always tell folks, you want that install done like someone’s expecting a hurricane, not just a drizzle. Honestly, sometimes the “quick jobs” end up being the longest fixes later…

That’s true for sure, but I gotta say—sometimes even the best prep just isn’t enough if the design’s working against you. My place is all original 1960s windows, and no amount of cleaning or careful bead work could stop the drafts till I added storm windows. Prep helps, but sometimes you just need a bigger fix. Anyone else notice that?
That’s the reality—sometimes you hit a wall with old windows, no matter how much you fuss over the details. I’ve seen it a lot: original frames just aren’t built for today’s weather. You do what you can, but eventually, you gotta bite the bullet and add storms or replace altogether. Drafts will find their way in otherwise.
