Immediate steps (first 30–60 minutes)

• Make it safe: avoid hazards and shut off sources if safe.

• Start drying: ventilation and extraction where appropriate.

When to call professionals

• Large affected areas or commercial spaces
• Water behind walls, under floors, or in insulation
• Sewage/blackwater contamination
• Mold risk (24–48+ hours of wet materials)
• Repeated incidents (you need root-cause diagnosis)

Documentation checklist

• Photos/video from multiple angles and rooms
• Timeline notes (when it started, when it stopped, what you did)
• Receipts for emergency mitigation and materials
• Names, dates, and summaries of conversations with providers/insurers

Local notes for California

• Even in drier climates, hidden moisture behind drywall or under flooring can cause long-term issues—moisture mapping matters.
• If your area is prone to seasonal storms or hillside runoff, ask about water diversion and prevention improvements after cleanup.
• Insurance documentation is often a big part of restoration—keep photos, timelines, and receipts from day one.
