What drives the final price
- Contamination size: Small localized jobs cost far less than multi-room or whole-house projects.
- Materials involved: Drywall, insulation, carpet, and structural wood removal add labor and rebuild cost.
- Containment and air cleaning: Larger jobs often require negative air, HEPA filtration, and more setup time.
- Moisture-source correction: If the leak, drainage, crawlspace humidity, or HVAC issue is still active, fixing that adds scope.
- Verification and rebuild: Clearance testing and reconstruction can meaningfully change the total project price.
Typical cost ranges
Single-room remediation
$3,000-$7,000

What a solid quote should include
- Containment approach and whether HEPA air filtration is included
- What materials are being removed versus cleaned in place
- How the moisture source will be addressed or coordinated
- Whether HVAC cleaning, crawlspace work, or dehumidification are part of the job
- Whether post-remediation verification is included or separately quoted
- What rebuild or finish work is excluded
How to compare quotes
- Get at least 2 to 3 written scopes.
- Compare containment, demolition, moisture correction, and verification line by line.
- Watch for vague language like “treat all affected areas” without listing what will be removed.
- Ask whether the contractor expects hidden damage to expand the scope after demolition begins.
- Do not choose on price alone if one bid skips source correction or clearance testing.
