Keeping Your Home Dry: Insulation Tips for Flood-Prone Areas

French drains definitely need TLC - seen plenty of soggy basements from neglected ones. Another overlooked tip: closed-cell spray foam insulation in flood-prone areas. Bit pricier upfront, but worth it to avoid moldy drywall nightmares later...trust me on this one.

Haha, preach! Learned this the hard way after our basement turned into a mini-swamp. Closed-cell foam was a lifesaver - my wallet cried at first, but my sinuses thanked me later. Totally worth it.

Wish I'd seen this thread sooner. We went with fiberglass insulation to save a few bucks, and after the first big storm, it was like a soggy sponge down there. Spent way more ripping it out and redoing everything than if we'd just gone with closed-cell foam from the start. Lesson learned, I guess...sometimes being cheap costs you more in the long run.

Did you notice any mold issues after the fiberglass got soaked? We had a similar experience in our historic place - went fiberglass initially because it seemed straightforward, but after one bad flood, it was a nightmare. Ended up switching to closed-cell foam too. Curious if anyone's tried mineral wool insulation in flood-prone basements...heard it's water-resistant but haven't seen many real-world examples yet.

We had fiberglass insulation in our basement too, and yeah, after one flood it was a soggy mess. Never tried mineral wool, but I've heard the same thing about its water resistance. Wonder if it's actually worth the extra cost, though... closed-cell foam sounds great but the price tag makes me hesitate. Has anyone found a middle-ground solution that's budget-friendly but still holds up decently after flooding?
