Water-damaged drywall and flooring in a residential room

A wall can look dry on the surface while moisture remains inside. That doesn't mean every wet wall requires demolition.

Start with the water source

Make sure the leak or water entry has stopped.

Look for changes

Possible clues include discoloration, soft drywall, bubbling paint, swelling, and musty odor.

Touch isn't a complete test

A surface that feels dry doesn't tell you everything about the material behind it.

Moisture measurement

Professionals may use moisture-measuring tools to help evaluate drying.

Don't close a wall around an unresolved moisture problem

If materials remain wet, trapping them behind new finishes can create additional problems.
