Plano homes tend to grow mold in predictable places. A slab leak creeping under a hallway floor on Blackland clay, an attic air handler dripping onto the ceiling below, hail-bruised shingles letting water into roof decking, or a bath fan venting straight into the attic instead of outdoors. Once the wet drywall and insulation are gone and the drying equipment has been hauled away, the piece most homeowners forget is the paperwork — and in Texas, one document in particular keeps its value for years afterward.
That document is the Certificate of Mold Damage Remediation, issued on TDI form MDR-1. It is not a marketing flyer or a workmanship warranty. It is the closing record of a regulated process that involves two separate licensed companies, and it matters to insurers, to future buyers, and to anyone who later needs to prove that a mold problem was handled the way Texas requires.
What the Certificate Actually Certifies, and Who Has to Sign It
The certificate is issued by the remediation contractor within 10 days of completion of the job, and it is signed by both licensees on the project — the mold assessment consultant and the mold remediation contractor. That dual signature is the detail that gives the form its credibility. Each company is attesting to its own piece of the work: that the remediation followed the written protocol and the work plan, and that the job passed clearance before containment came down.
It helps to separate the certificate from the documents that come before it, because people often blur them together. The assessment report and remediation protocol come first, from the assessment consultant, and must reach you at least a day before work starts. The work plan comes from the remediation contractor. The clearance report is the consultant’s written confirmation — after a visual inspection and any sampling the protocol called for — that the water cause was fixed and the work passed. The Certificate of Mold Damage Remediation is the final layer on top of all of that, and it is the one a lender, an adjuster, or a buyer is most likely to ask for.
Keep it somewhere you will actually find it again. A PDF in cloud storage plus a paper copy with your closing documents is reasonable. The state entitles buyers to copies of the certificate for five years after the work, which tells you how long this piece of paper is expected to stay relevant.
One practical note: the certificate exists because the work was done by licensed companies under a regulated sequence. If you are still at the comparison stage and gathering bids for mold remediation plano tx, it is worth asking each company up front how they handle the certificate and who signs it — a vague answer at the bidding stage usually predicts a vague answer at the end.
How the Certificate Fits the Two-Company Texas Process
Texas regulates mold work more tightly than most states, and the certificate only makes sense inside that framework. Under Occupations Code chapter 1958, mold assessment and mold remediation each require a license from the Texas Department of Licensing and Regulation, and the same company may not perform both roles on your project. That separation is deliberate: the company that clears the job is not the company that got paid to do it.
The rules engage at 25 contiguous square feet of mold. Below that line, a homeowner can clean it up personally or hire anyone. At or above it, hired work runs through the licensed sequence. A licensed assessment consultant inspects, maps moisture through the affected area, and writes a project-specific protocol naming the rooms, the materials to be removed, the containment approach, and how clearance will be judged. A different licensed remediation contractor then writes a work plan to carry out that protocol, notifies TDLR at least five days before starting — or by the next business day in a water-damage emergency, with a $25 fee — builds containment, removes the moldy material, and dries the space. The consultant returns to clear the job before containment comes down.
Only then does the Certificate of Mold Damage Remediation get issued, signed by both sides. Notice what the form represents: a second, independent licensed party has already confirmed the result. When someone hands you an MDR-1 signed by only one company, or by a company that ran the whole job start to finish, that is a reason to slow down and check licenses through the TDLR’s online license search before you accept it.
Before any work begins, ask for the Consumer Mold Information Sheet, proof of at least $1 million in liability insurance, and the written protocol. Unlicensed assessment or remediation in Texas is a Class C violation carrying penalties of $2,000 to $5,000 per violation — and an unlicensed job cannot produce a valid certificate at all.
What the Certificate Does for Insurance, Resale, and Rental Situations
The certificate’s most immediate use is with insurers. Texas rules provide that an insurer may not underwrite against the remediated damage the certificate documents — in plain terms, a properly closed-out mold claim should not be used to deny or penalize your coverage later on the basis of that same remediated area. That protection depends on having the form, signed and dated, along with the clearance report and photos of the original condition. If you sanded, scrubbed, or bleached a large patch before anyone photographed it, you have made your own claim harder to support.
For resale, the five-year buyer entitlement makes the certificate part of a Plano home’s disclosure story. A seller who can produce a protocol, a clearance report, and an MDR-1 signed by two licensed companies is answering questions before they are asked. A seller who can only say “we had someone take care of it” is inviting a negotiation.
Renters and landlords have their own version of this. In apartments, condos, and HOA-governed properties — a large share of the Plano housing stock — responsibility for water damage and mold often splits between owner and occupant, and Texas Property Code 92.052 sets out a renter’s right to request repairs. Whoever pays for the remediation should be the one holding the certificate, and a renter who paid out of pocket should insist on receiving a copy.
On cost, be clear about how the invoices break down: assessment, protocol, and clearance are billed separately by the assessment consultant, while the remediation work is billed by the other company. Published national planning ranges can give you a rough sense of scale, but actual Plano quotes come from the companies themselves after they have looked at the specific space — and no quote should ever be treated as final before the protocol is in hand.
If the ten-day window passes and no certificate shows up, follow up with both licensees in writing, since the form requires both signatures to be complete. Keep the dated correspondence with the rest of the file. The certificate is the last page of the story, and it is the page that keeps working for you long after the fans are gone.
