Check your mold remediation quote
Most homeowners get one bid, feel the number is high, and have no way to know. This tool won't tell you whether the contractor is good. It will tell you whether the price is in the normal range for the size of the job and whether the scope is missing the things that make remediation actually work.
Quote review
Ranges are national averages from published cost data and contractor quotes. Local labor rates, access, and what's found once walls open all move the number. This is not an appraisal of any specific contractor.
What a complete remediation quote includes
| Line item | Why it's there | If it's missing |
|---|---|---|
| Moisture source | Mold is a water problem with a mold symptom | The job will need doing again |
| Containment and negative air | Keeps spores in the work area | Cross-contamination of the rest of the house |
| Material removal | Porous materials can't be cleaned | Regrowth behind new paint |
| HEPA vacuum and wipe | Physically removes spores and fragments | Spraying alone leaves dead mold, which is still an allergen |
| Independent clearance | Proof it worked | You are taking their word for it |
| Line-item scope | Lets you compare and lets insurance pay | No way to check the math |
Frequently asked questions
How much should mold remediation cost per square foot?
Roughly $10 to $25 per square foot of affected area for a typical job, with a minimum charge around $500 to $1,500 even for small areas. Attics, crawl spaces, and HVAC systems run higher because of access. Sewage and floodwater add for the extra protective work. Rebuild is usually on top.
Is a cheap mold quote a bad sign?
Often. The cheapest way to "remediate" is to spray something and paint over it, and that is what a very low bid usually buys. Check whether containment, removal, and an independent clearance test are in the scope. If they are and the price is still low, that can just be a lean local company.
Should I get multiple mold remediation quotes?
Yes, at least two, ideally three for anything over a couple thousand dollars. Make sure each one is scoping the same square footage, otherwise you are comparing different jobs. A written line-item scope makes that possible.
Does the contractor need a license?
Depends on the state. Florida, Texas, New York, Louisiana, and a few others license mold assessors and remediators and separate the two roles. Most states have no mold-specific license. See the state mold laws guides for your state.
What is a clearance test?
Post-remediation verification. An assessor separate from the remediation company inspects the area, checks moisture, and usually takes air or surface samples to confirm levels are back to normal. If it fails, the remediator comes back. It is the single best protection you have.
