Structural drying in San Mateo, CA

Structural drying questions
Do I need a permit for repairs in San Mateo?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of San Mateo Building division.
Does insurance cover earthquake damage in San Mateo?
Not by default. Earthquake coverage is a separate policy, often through the California Earthquake Authority, and it has its own deductible.
Why not just use fans?
Fans move air but don't remove moisture from it. Without dehumidification, the water evaporated from your walls stays in the room and soaks back into other materials.
Do walls always have to be cut open?
No. Many clean-water losses dry in place with small access holes. Walls are cut when water is contaminated, insulation is soaked, or readings won't come down.
