A buddy of mine got an inch of water in his house from the floods recently. Insurance says he needs to remove several feet of drywall throughout the house, remove cabinets, etc. Does that sound right for that much water? Is there any other way to keep the mold from growing, other than removing that much drywall?

ETA his insurance coverage isn’t big enough to cover the cost to do all that plus remove floors and other demo and repairs.

ETA2 water was out of the house within a couple hours.

Any amount is too much.

Rip out the cabinets, cut 4 ft from the floor, call it a day

No, and if he goes to sell it without fixing it correctly, he's screwed. Sucks, but unless there was some extremely weird situation he should have been fully insured.

He’s either gonna rip it out now or later after he finds mold growing.

How long was the water in his house?

More than a day? Yep drywall wicks water. Remove 4ft up from the floor. Cabinets and anything other than tile/lvt floors gotta go.

If his insurance doesn't cover it, tell him to take a week off and Rip it out himself. A demo/remediation guy will charge him 10k to send a couple kids in there with a sawzall, some cro-bars and a roll away. He could do it himself for 1k.

Full sheets are easier to install

Is that why 4 feet is pretty standard for demoing?

mold is not some alien substance.
remove the moisture and kill it with white vinegar, baking soda and water

if you want to remove drywall cut it back in 24” increments

Unfortunately, drywall sucks moisture up. I had 3" in a house for about 6 hours and ended up having to completely gut the thing to the tune of about 150k.

Snap a line 4' off the floor, cut the drywall on that line, and rip everything out below the line. All insulation has to go. Get someone to come in or get your hands on a moisture tester to see if you have mold supporting moisture above four feet. If so, keep going in 2' increments until what's left is dry.

It sucks and it's part of why your home owner's doesn't cover flood. One inch of water can require tens or hundreds of thousands of dollars of remediation due to the threat of mold and fungus.

Drywall should be installed 1/2 inch off slab. Cut should be 48 1/2 inches

Every situation is different so no “one size fits all answer.” Standard sheets are 4x8 and not too difficult to rip a piece into two 2x8 pcs. Always want to go in 24” increments.

I haven’t priced Sheetrock in a while so not sure what would be more cost effective. But I’m certain your contractor will have an opinion.

Whatever you do, just make sure you get 3 quotes and compare price, time, and overall competence. Make sure they are licensed and insured.

Yeah, paying for extra material to replace in standard sizes is often cheaper than saving a few bucks on material by only demoing the bare minimum and then paying a guy to cut sheets to perfectly fit everything and then mudding and floating all those joints.

He chose his flood insurance coverage amount at the time of application. Flood insurance is cheap in many cases so shame on him for not buying enough. Unless his would’ve been expensive due to being in a flood zone. In that case, I say shame on him for being in a flood zone and not having enough coverage.

One inch of water is enough to do $100,000 of damage or more. I don’t understand why anyone in their right mind in southeast Louisiana wouldn’t have enough flood insurance after watching what happened in 2016. I hope he increases his coverage going forward.

Good news is Sheetrock is cheap and the work isn’t too difficult for most able-bodied people so if all else fails, he and a few buddies can do the Sheetrock work themselves.
