When mold remediation is complete, you should walk away with a specific set of documents. These protect you for insurance claims, real estate transactions, and future disputes. Many homeowners do not know to ask for them — and some contractors do not volunteer them.
The Document Package You Need
1. Pre-remediation assessment report
Written by an independent inspector before work began. Includes:
- Inspector's credentials
- Date of inspection
- Sampling locations and methods
- Lab results identifying mold species and counts
- Scope of work recommended
- Photos of affected areas
This is your before-state documentation. Without it, you cannot prove what was there before remediation.
2. Contractor's written scope of work
From the remediation contractor. Includes:
- Square footage of affected area
- Materials removed
- Containment approach
- Equipment used
- Timeline of work performed
- Signed by contractor
This is your record of what was done. Get it before work begins and keep the executed copy after work is done.
3. Before and after photos
The contractor should provide photos of the affected area before work begins and after completion. These are part of the job record.
4. Post-remediation clearance test report
Written by an independent inspector after work was completed. Includes:
- Inspector's credentials (different from the remediating contractor)
- Sampling locations and methods
- Lab results showing post-remediation spore counts
- Comparison to pre-remediation and outdoor baseline levels
- Pass/fail determination
This is your confirmation the work was done correctly. It is the most important document in the package for insurance and real estate purposes.
5. Contractor's warranty (if applicable)
If the contractor offered a warranty against recurrence, get the terms in writing including what is covered, what voids coverage, and how to make a claim.
Why Each Document Matters
For insurance claims: Insurers want to see the scope of work, proof it was professionally completed, and the clearance test confirming success before releasing final payment.
For real estate transactions (selling): Buyers and their lenders will want the full documentation package to confirm the issue was addressed professionally. The clearance test report is typically the document lenders focus on.
For real estate transactions (buying): If the seller remediated mold before closing, request the complete documentation package as a condition of the sale. Do not close without it.
For future disputes: If mold returns and you believe the original job was inadequate, the documentation package is your evidentiary record for any contractor dispute or warranty claim.
How to Request the Documents
Ask for all documentation in writing before work begins. Include it in your contract: "Contractor will provide pre-remediation photos, written scope of work, post-remediation photos, and will recommend post-remediation verification by independent inspector."
For the clearance test report, hire the inspector yourself — do not rely on the contractor to arrange it. The inspector you hire for the clearance test should be independent of the remediating contractor.
If a contractor is unwilling to provide documentation or discourages you from requesting a clearance test, that is a significant red flag about the quality of their work.
