Mold Removal 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.
Is bleach enough to kill mold?
Not on porous materials like drywall and wood. Bleach mostly lightens the surface. Porous materials with growth are usually removed, and the moisture source has to be fixed.
Do I need mold testing?
Not always. If mold is visible, the priority is removing it and fixing the moisture. Testing helps when you smell mold but can't find it, or when clearance is required.
