Water damage restoration in Los Angeles takes 1 to 12 weeks. Emergency extraction takes 1 to 2 days. Drying takes 3 to 5 days. Mold remediation takes 1 to 2 weeks. Full rebuild takes 4 to 12 weeks.
Water extraction with truck-mounted pumps. Board up if needed. Assess source (burst pipe, appliance, roof leak, flooding). Stop the source.
Industrial dehumidifiers, air movers, and extraction equipment. Remove standing water from all affected areas. Document for insurance.
Monitor moisture levels with meters. Continue dehumidification until walls, subfloor, and framing reach dry standard (<15% moisture). Remove wet drywall and insulation.
Apply antimicrobial treatment. If mold present: containment, HEPA filtration, removal of affected materials, clearance testing. LA County requires licensed mold remediation for large areas.
Insurance scope finalized. Materials ordered. Permits if needed (plumbing repair, electrical, structural).
Replace drywall, flooring, cabinets, fixtures as needed. Paint. Final inspection. Insurance final payment.
Homeowner's insurance typically covers sudden water damage (burst pipes, appliance leaks). It does NOT cover gradual damage (slow leaks), flooding (separate flood insurance needed), or negligence.
Within 24-48 hours. Mold can begin growing in 24-72 hours in LA's warm climate. Immediate extraction and drying prevents mold and reduces total restoration cost.
