House is flooded, need advice for wood floors

I can't imagine those will be salvageable

Your floor is gonna need to come up. Shovel mud out with a flat shovel

My reply will go against the adv ice of everyone else, but here goes.

The house I was living in during Katrina was my grandpa's old house in Lakeview (NOLA). It is a raised house built in the '20s with hardwood floors throughout.
The flood water stayed in the house for 2 weeks. And the floors never did buckle. They were sanded and revarnished, and no problems.

You might wait and see what they do.

I had polyurethaned plywood floors in my camp. Used an electric (lower pressure) pressure washer and a shop vac working in tandem with a buddy. Had a few bubbles (it was plywood) but when it dried completely you couldn't see where any bubbles had been. Believe me, I tried everything else we could think of. That fine silt is usually sticky when it dries, forget hoping you'll be able to sweep it out

LMAO at the people who do not understand the difference between hardwood flooring and laminate or other engineered bullshite.

Wash them with a waterhose and mop or squeegee as not to split the grains and then allow to air dry if possible, if it is tounge and groove you mak have to add a few toe nails to aleviate buckling but dry it slowly as possible. By doing so too quickly (serve pro method) will cause to massive buckling and it will be ruined.

Type of wood is paramount as well.

Unfortunately I learned this the hard way.

I think it will depend on the kind of wood and how much water damage there is.

My old house by City Park had heart pine floors and took a few inches of Katrina water. Insurance gave me enough for full replacement, but I just rented a floor sander and applied polyurethane. It had gotten slightly swollen/cupped on some of the edges, but the sander smoothed that right out. It hadn't buckled up and the old pine was dark enough to not even need stain.

If it's just silty, shop vac and mop a few times until you can determine if the finish is OK.
