Just depends how much you want to gamble on paint cycles vs. dent resistance, I guess.
Funny you mention that—I've patched more than a few vinyl panels after a rogue baseball or hailstorm. Fiber cement’s paint does get chewed up by salt air, but at least it doesn’t crack as easy. Have you seen any of the newer composite sidings in action near the coast? Curious if they’re actually living up to the hype or just another maintenance headache.
I’ve been watching a couple of those composite installs on the waterfront, and honestly, it’s a mixed bag so far. One place looked great after two years—no warping, color still sharp—but another had weird fading and some edge swelling. I guess it comes down to which brand you pick and how good the install crew is. If you’re flipping or renting, sometimes just picking the “least bad” option is the real win. Salt air really does not play fair with any material...

Ain’t that the truth. I’ve seen “maintenance-free” composites turn into science experiments after a couple years near the water. Installer skill matters, but some brands just can’t handle the salt—even if the marketing says otherwise. Sometimes good old pressure-treated lumber (with a ton of sealant) outlasts the fancy stuff, weirdly enough.

I get where you’re coming from, but I’ve actually had the opposite experience. My neighbor’s deck with pressure-treated boards started warping and splitting after just a few years—even with regular sealing. Meanwhile, my PVC boards are holding up way better (so far). Maybe it comes down to picking the right composite brand and making sure there’s enough airflow underneath? Salt air is brutal, but I’m still not ready to go back to wood.
Pressure-Treated Wood Didn’t Last for Me Either
Funny, I always thought pressure-treated was the “safe” choice too, but it really depends. When we moved into our place near the coast, the deck was only about five years old, all pressure-treated pine. Looked solid at first, but after our second winter, boards started curling up at the edges and a couple even split right down the middle. I tried sanding and resealing, but it felt like a losing battle—almost like the salt air just eats through whatever you put on it.
I’m not made of money, so I was hesitant to go for composite or PVC. Ended up patching with some leftover cedar planks from a friend’s project (not ideal, but hey, free wood). Oddly enough, those cedar boards have held up better than the original pressure-treated ones. Maybe it’s just luck or maybe cedar’s natural oils help a bit with the salt?
I’ve heard airflow makes a big difference too. Our deck is pretty low to the ground, so maybe that trapped moisture and sped up the damage. If I ever redo it, I’m tempted to try composite, but I keep hearing mixed reviews about fading and getting hot in the sun. Still, anything’s better than replacing warped boards every couple years.
Guess there’s no perfect answer when you’re this close to the ocean... just gotta pick your battles and hope for the best.
