Interior demolition: what it involves
Not every flooded house comes down. When repairs stay under the substantial damage limit, or the home is elevated, the work starts with a gut-out: everything water touched comes out so the framing can dry, be treated and be inspected.
Interior demolition is careful work. Plumbing, wiring and walls that stay have to be protected, and older homes may have asbestos in flooring, popcorn ceilings or joint compound, which means testing before tearing out. The goal is a clean, dry shell that the inspector and the rebuild contractor can work from.
What an interior gut-out removes
- Wet drywall and plaster cut out to the flood line or to the ceiling
- Insulation, baseboards, trim and doors
- Flooring and tack strips, tile and underlayment
- Kitchen and bath cabinets, counters and fixtures
- Appliances and water heater, recycled where possible
- Debris hauled off and the shell swept clean for drying

Interior Demolition & Flood Gut-Outs questions
Do I need a permit to gut a flooded house?
Most cities require permits for repair work on storm-damaged homes, and some require them for removal of drywall and fixtures. Check with your city's building department before work starts.
How high should the drywall be cut?
Usually a few feet above the water line, so wet insulation and hidden mold come out too. The contractor confirms it room by room.
Can you leave the kitchen cabinets?
Only if they stayed dry. Particleboard cabinets that sat in floodwater almost always have to go.
