When a homeowner in Plano spots dark staining on attic decking or a musty smell with no obvious leak, the instinct is to call the first remediation company that answers. That instinct is understandable and, in Texas, it is also the fastest way to end up with a scope of work that serves the contractor’s bottom line more than the house. The document that decides how much drywall comes out, what containment goes up, and what “done” actually looks like is called a remediation protocol. If the same company that profits from tearing out material also writes the rules for how much material gets torn out, no one in the transaction is checking the math except the person who benefits from it. That is the whole reason Texas built a firewall between the two jobs.
The Conflict of Interest Built Into a Self-Written Protocol
A protocol is not a sales proposal. It is a project-specific technical document that names which rooms are affected, how much material is contaminated, what methods will be used, how containment will be built, and — critically — how clearance will be judged when the work is finished. Whoever controls that document controls the size of the invoice. A company that both writes the protocol and performs the removal has an obvious incentive to inflate the scope, because every additional sheet of moldy drywall and every extra day of HEPA filtration is billable. The opposite incentive is just as damaging: a low-ball protocol wins the bid, and change orders arrive once containment is already up and the family is out of the house.
There is a second, quieter problem. Clearance is supposed to be an independent verdict — a visual inspection, any samples the protocol calls for, and a written passed report before the containment comes down. When the party being judged is the party doing the judging, the clearance report stops functioning as a check and becomes a formality. Separation of duties is not bureaucracy; it is the mechanism that makes the paperwork mean something.
Texas treats this seriously. Under Occupations Code chapter 1958, mold assessment and mold remediation each require a separate license from the Texas Department of Licensing and Regulation, and the same company may not perform both on one project. The rules attach at 25 contiguous square feet of mold. Below that line, a homeowner may clean the area personally or hire anyone; at or above it, hired work has to follow the licensed sequence. Anyone offering to inspect, write the scope, and remediate the same job is either unfamiliar with the rule or hoping the customer is.
How the Two-Company Sequence Works in Plano and Collin County
The sequence starts with a licensed mold assessment consultant, who inspects the property, maps moisture, decides whether samples are genuinely needed, and writes the remediation protocol. That protocol must reach the property owner at least a day before work begins, so there is time to read it and compare it against competing bids. A separate licensed remediation contractor then writes a work plan to carry out that protocol — a plan that follows the assessor’s scope rather than redefining it — and notifies TDLR at least five days before starting, or by the next business day in a water-damage emergency, with a $25 fee.
Only then does containment go up, moldy drywall and insulation come out, and drying begin. Before the plastic comes down, the assessment consultant returns, checks the work visually, takes any samples the protocol specified, confirms the underlying water cause was fixed, and issues a written passed clearance report. Within 10 days of completion, the contractor provides a Certificate of Mold Damage Remediation on TDI form MDR-1, signed by both licensees. That certificate matters longer than most people realize: insurers may not underwrite against the remediated damage it documents, and buyers are entitled to copies for five years.
The local scenarios make the value of an independent scope obvious. Plano sits on Blackland clay that shifts with moisture and stresses slab plumbing, so a slow slab leak can wet a baseboard for months before anyone notices. Attic air handlers and condensate lines drip onto decking. Bath fans vent straight into attic space instead of outdoors. Hail-bruised roofs let water in behind the ceiling stain. In each case, the honest question is not “how much mold can we sell” but “what actually got wet, what is still wet, and what has to come out.” A protocol written by the person who will remove the material rarely asks that question as carefully as it should.
Searching for Mold Remediation Companies Near Me Without Getting Played
Search results for mold remediation companies near me are crowded with businesses that describe themselves as full-service — inspection, testing, removal, clearance, all under one roof. Some are legitimate specialists in one half of the sequence and simply market broadly. Others are counting on the fact that most homeowners do not know the two-company rule exists. The practical defense is a short list of questions asked before anyone walks through the door: Who will write the protocol, and is that a different licensed company from the one doing the removal? What are both license numbers? Can I see the written protocol before work starts? Is there a certificate of insurance showing at least $1 million in liability coverage, and will you hand over the Consumer Mold Information Sheet?
Every license can be verified in minutes at tdlr.texas.gov/LicenseSearch, and unlicensed assessment or remediation carries a Class C violation with penalties of $2,000 to $5,000 per violation. That lookup is the single highest-value five minutes in the entire project. So is understanding the invoice structure: assessment, protocol, and clearance come from one company, remediation from another, which means two vendors and two sets of invoices. Published national planning ranges from sources such as This Old House, Fixr and HomeAdvisor give a rough sense of scale, but actual numbers come from the companies themselves after they look at the job — and any quote that bundles everything into one line item deserves scrutiny.
Free quote services exist to shorten the search. Plano Mold Experts, for example, is a no-obligation service that passes a description of the problem to independent TDLR-licensed assessment and remediation companies serving Plano, Frisco, McKinney, Allen, Richardson, Wylie, Murphy, The Colony and Carrollton; those companies contact the homeowner directly, and the service itself does not perform the work. That is a useful head start, not a substitute for verification. Handling the water quickly still matters most: the EPA notes that wet materials dried within 24 to 48 hours usually do not grow mold, and if contamination may be in or near the air handler or ducts, the system should stay off until it has been checked. Photograph the original condition before anything moves, keep children and pets out of the area, and let the paperwork — protocol, work plan, clearance report, MDR-1 — tell you whether the job was actually done.
