Winter storms bring days of heavy rain, flooding streets and causing mudslides on hillsides and burn scars.
Many older homes are on raised foundations with crawlspaces, and hillside homes face mudslide and drainage risks during heavy rain. Many LA bungalows and Spanish-style homes from the 1920s–40s have raised foundations with crawlspaces where plumbing runs exposed. Apartment buildings and condos across the city, including many soft-story buildings retrofitted for earthquakes, see leaks travel between units.
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.

Sewage & Biohazard Cleanup questions
How do I clean wildfire ash from my Los Angeles home?
Avoid sweeping, which stirs up ash. Use a HEPA vacuum, wet-wipe hard surfaces with protective gear, and have smoke odor professionally treated.
How do I verify a California contractor?
Search the Contractors State License Board (CSLB) license lookup.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
