Frequently Asked Questions
How much does mold remediation cost per square foot?
National 2025 rates run about $10–$30 per square foot. Surface mold on a dry wall is $10–$16, moderate growth behind drywall is $15–$25, and severe water-damaged or structural mold is $22–$30. A small job typically lands around $500–$1,500 and a whole-home remediation can exceed $10,000.
Does mold remediation cost include rebuilding?
No. Remediation and clearance testing cover removal, containment, HEPA cleaning, and air sampling only. Reconstruction - new drywall, flooring, paint, and trim that had to be torn out - is billed separately and can equal or exceed the remediation cost when water damage is involved.
Can I remove mold myself?
You can clean small surface patches under about 10 square feet on hard surfaces with detergent. Anything larger, any black mold (Stachybotrys), or mold tied to a water leak warrants a certified remediator with containment and negative-air HEPA filtration to avoid spreading spores throughout the home.
Why is post-remediation testing worth paying for?
The $300–$600 clearance air-sampling step is what proves the affected space is actually safe and that spore counts have returned to normal. It protects your health, documents the work for insurance, and is often required disclosure at resale.
