Downtown and Raymond Hills have 1920s–1940s homes. Sunny Hills and Golden Hills have mid-century homes on hillside lots. Many homes near downtown and Cal State Fullerton are older houses divided into rentals, with added bathrooms and aging water heaters. Tenants change each year, so slow leaks under sinks and behind showers can run for months before anyone reports them. Hillside homes in Sunny Hills and Golden Hills have sloped lots with drainage challenges, and mid-century homes there often have original copper plumbing under the slab.
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 Removal questions
Do I need a permit for repairs in Fullerton?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Fullerton Building and Safety division.
Is a slab leak covered by insurance in Fullerton?
Many policies cover the water damage and access costs from a sudden slab leak, but not the pipe repair itself. Report it quickly and keep photos and the plumber's findings.
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.
