What the Certificate Is
A Certificate of Mold Remediation is a formal document issued under Texas Occupations Code Section 1958.154 after a licensed mold remediation project is completed. It records what was remediated and confirms the work met the clearance criteria defined in the assessment protocol.
It is not a receipt or a contractor's invoice. It is a regulated document tied to Texas's mold licensing framework, and it carries weight with buyers, lenders, and insurers precisely because of that.
Who Issues It
Texas separates assessment from remediation deliberately. A licensed mold assessment consultant writes the protocol before the work and evaluates the property afterward against that protocol. The certificate reflects that independent evaluation.
Texas Occupations Code Section 1958.155 prohibits the same company from performing both the assessment and the remediation on the same project, and bars common ownership between the two firms. The rule exists so the party certifying the work is not the party that performed it.
The Five-Year Seller Obligation
If a certificate was issued for a property, the seller must provide a copy to the buyer for any certificate issued in the five years before the sale. This flows from Section 1958.154 and is echoed in the standard TREC residential contract.
Keep the certificate with your closing documents and warranty paperwork. Sellers who cannot produce it during a transaction create exactly the doubt the document was designed to eliminate.
Why Buyers Should Want to See It
- It confirms licensed professionals performed the work rather than an unlicensed handyman
- It documents the scope — what area was affected and what was done about it
- It shows the work was evaluated against defined clearance criteria by an independent assessor
- It gives lenders and insurers something concrete when mold history comes up in underwriting
