What Makes Orange County Different
Orange County is dry most of the year, so most water damage starts inside the home. Many houses were built in the 1960s and 1970s on concrete slabs, and aging copper pipes can develop pinhole leaks or break under the slab. A warm spot on the floor, a sound of running water or a jump in the water bill can point to a slab leak. Supply lines to toilets, sinks and washers are another common source.
Winter storms are few but can be strong, and heavy rain can find old roof leaks and flood low streets and yards. Near the coast, damp marine air keeps some homes cool and humid, and mold can grow in closets and bathrooms with poor airflow.
Wildfires in the canyons and foothills, often driven by Santa Ana winds, can fill homes with smoke and fine ash even miles away. Close windows, run a HEPA air cleaner and wash ash off with water rather than sweeping it dry. Homes from this era often have popcorn ceilings and flooring that may contain asbestos, and paint from before 1978 may contain lead, so test before you remove them.

Checking a License in Orange County
California requires a license from the Contractors State License Board for most home repair work. Look up any company’s license number on the board’s website before you sign, and check that it is active and bonded and that workers compensation insurance is on file. California has no separate state mold license, so ask whether the technicians hold industry certification in water damage and mold remediation. Asbestos work needs its own certification, so ask about it by name when a job may disturb older materials.
