I posted this on the OT and someone suggested I should post it here.

A buddy of mine got an inch of water in his house from the floods recently. Water was gone and out of the house after a couple hours. 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.

1-2 feet is standard to ensure there’s no moisture remaining. Any moisture that does not dry will grow mold.

Well, it's not just the drywall, it's also the insulation in the exterior walls that will have to be removed up to a certain level due to it absorbing water and acting like a sponge with a couple inches of water running up a foot or so in the pink stuff.

Why does he not have enough flood coverage? Did he buy a minimum amount of coverage or does he just not understand his policy and his claim? Did he meet the requirements to have replacement cost on his policy?

Our insurance only paid for a couple of feet above the water line. We actually tore out too much for advice like this and had to pay out of pocket for the additional s.f.

Cut a straight line two feet above the waterline and pull out the wet insulation. You can push new insulation up the cavity pretty easily.

Unfortunately, cabinets get in the way of tearing out the sheetrock. I think mine would have been fine if we could have figured out a good way to move them from the wall. Our island dried out fine.

Does this actually produce any cost savings? I realize you will use less material this way, but if you just rip it out at the seam it is way easier demo and less labor, and less dust.

Growing up our house flooded a couple or three times, and my dad always just popped the drywall at the seam. He'd have the house gutted, floated and finished in about 5 days.

Taking them out at the seam probably would be better.
