Mold removal
Mold remediation in San Luis Obispo, 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.

Marine humidity leads to mold in older homes.
Downtown has early-1900s homes with raised foundations. Laguna Lake has mid-century homes, and many homes near Cal Poly are rentals. Many homes near Cal Poly and downtown are older houses rented to students, with aging plumbing, water heaters and older roofs. Cool, damp winters and marine air keep raised floors and bathrooms moist, so leaks lead to mold faster than in the inland valleys. Homes near San Luis Obispo Creek face flooding during big atmospheric river storms, as in January 2023.
Licensing in California: California requires contractors on jobs of $500 or more (labor and materials) to be licensed by the Contractors State License Board (CSLB). Check the license on the CSLB website.

Mold remediation questions
Do I need a permit for repairs in San Luis Obispo?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of San Luis Obispo Building and Safety division.
Who handles water damage in a San Luis Obispo rental?
Landlords usually handle the building, while tenants need renters insurance for their own belongings.
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.
