Begin by removing all baseboards along every wall with water damage. (Baseboards are the wood trim that sits against the bottom of your wall). Even if only the floors were wet, removing the baseboards allows the walls to vent out moisture, and if the sheetrock will be removed, the baseboards should come off first.

Again, document this in detail photograph.

Sheetrock sometimes in 4'x8' sheets, although sometimes a 2 feet wide sheet is cut to fill spaces. Try to remove sheetrock in the largest sections possible. This makes removal easier. Remove sheetrock to 1 foot above the high water line at a minimum, but if you have more than a foot of water damage, then you want to remove up to the driest point. Often, sheetrock will be installed horizontally (with the long side lying sideways). If that is the case and you have quite a bit of water damage, lift the bottom and pull upwards gently. Sometimes the sheet will split at the seam (4 foot height). Documenting this is important because the appraiser is going to decide whether you need 1' replaced, 2' or 4' and this is all totalled to come up with the price for your sheetrock replacement (part of their formula).

On exterior walls that are insulated, remove all damp insulation behind it. Insulation needs to be removed with gloved hands. Depending on the type, it may be filled with fibers that will itch so cover your hands.

Removing cabinets with sinks or electrical installed can be tricky. If you aren't sure you can do it safely, open up the cabinets and try to remove the bottom panels if possible to help them dry out.
