Permits and licensing

  • This work rarely needs a permit, but a town can still require one for parts of it.
  • Licensing depends on the state: a trade license in some, a home-improvement registration in others, none in the rest. The finder shows what the record says where one exists.

Know what you're looking at

  • Two yellow handheld moisture meters, one with a bar of lights and one with a digital screen.

    Moisture meters help an inspector find damp walls and floors that look dry. A reading points to a place to look closer; it does not by itself prove a leak.

    A meter reading against a wall or floor can show hidden moisture from leaks or condensation. Ask the inspector to explain any high readings and what could cause them.
