Most of California's rain falls in a few months. The state's Office of Environmental Health Hazard Assessment puts about 75 percent of the year's precipitation between November and March. In the winter of 2022 to 2023, NOAA counted nine atmospheric rivers in three weeks that brought almost half of a normal year's statewide precipitation, with flooding and landslides. Closer to home, the California Department of Public Health lists common sources of indoor moisture, including a leaky roof, plumbing leaks, sprinkler spray hitting a building and a damp crawl space.
California does not license mold remediation, so there is no state license to search for. This directory lists the companies by city, with their ratings, review counts and the services their own websites describe.
