Mold removal
Mold remediation in Berkeley, CA
Mold remediation removes mold growth under containment so spores don't spread, cleans or discards affected materials, and corrects the moisture problem that let it grow. Several states, including Texas, Florida, Louisiana and New York, license mold remediation, so check your state's rules.

Other risks in Berkeley
Hillside runoff and slides
Heavy rain sends water and mud toward homes on steep Berkeley Hills lots, especially where retaining walls and drains are old.
Earthquake pipe damage
The Hayward Fault runs through the city, and a quake can crack supply lines, gas lines, water heaters and foundations.
Student rental leaks
Rentals near campus change tenants every year, and slow leaks under sinks and showers can run for months unreported.
Older plumbing
Century-old homes have galvanized supply lines and cast-iron drains that leak, clog and corrode with age.
Signs you need mold remediation
- Visible black, green or white growth on drywall, baseboards or wood
- A musty odor in a closet, bathroom or HVAC closet
- Recurring condensation on AC vents or ducts

What affects the cost
Prices depend on the job, so restoration companies in Berkeley quote after an assessment. The main drivers are how much area is affected, how long it stayed wet, and what has to be removed or rebuilt. See the full list of mold remediation cost factors.
Mold remediation questions
Do I need a permit for repairs in Berkeley?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Berkeley Permit Service Center.
Does insurance cover earthquake damage in Berkeley?
Not by default. Earthquake coverage is a separate policy, often through the California Earthquake Authority.
Do I need a licensed company for mold removal?
It depends on your state. Texas, Florida, Louisiana and New York license mold remediation above set sizes. In other states, look for IICRC-certified remediators, insurance and a written scope.
Does bleach kill mold?
Bleach can whiten mold on hard, non-porous surfaces, but it doesn't penetrate drywall or wood and adds moisture. Removal and cleaning, plus fixing the moisture, is the reliable fix.
