Mold remediation removes active mold growth and fixes the moisture problem feeding it. Cost scales with the affected area and location — a bathroom wall is cheap, an attic, crawl space or HVAC system is not.

Mold remediation runs about $1,100–$6,000, around $2,200 typical. Small surface jobs can be a few hundred dollars; whole-attic or HVAC contamination can exceed $10,000.
Does insurance cover mold remediation?
Usually only if the mold resulted from a sudden, covered water event (like a burst pipe) — not from long-term leaks or humidity. Check your policy's mold rider and caps.
