The short answer
Mold remediation in California typically runs $1,500 to $6,000 for residential events. Small visible spots stay in the $500 to $1,500 range. Wall-cavity or whole-room mold from a major water event runs $5,000 to $15,000-plus. Insurance coverage depends on the source — mold from a sudden burst is usually covered, mold from a long-ignored drip usually isn't.

Most California homeowners pay only their deductible. We document everything to insurance-adjuster standard so claims don't get pushed back.
How the claim flow works
- Call us first. We dispatch and start mitigation. Your policy requires immediate action to limit damage.
- We document on arrival. Moisture readings, photos, scope of work. The same evidence package adjusters use.
- You file the claim. Or we help. Most carriers will speak directly to our office with your authorization.
- We bill the carrier direct. You pay your deductible only, in most cases. No upfront charge for emergency mitigation.
Time-sensitive: California policies have "duty to mitigate" language. If you wait too long to call a restoration company, the carrier can deny part of the claim for damages that spread during your delay. Call within 24 hours of discovery.
