Texas handles mold work differently from most states, and the difference shows up first in the paperwork. Once hired work reaches 25 contiguous square feet of mold, the job splits into two licensed roles that cannot be filled by the same company. A TDLR-licensed mold assessment consultant inspects the property, maps moisture, decides whether samples are even necessary, and writes a project-specific remediation protocol. A separate TDLR-licensed remediation contractor then writes a work plan to carry out that protocol — not to redraw it. The protocol has to be in your hands at least a day before work begins, which means you have a real window to read it while nothing is moving and nobody is standing in your hallway waiting for a signature.
The most useful way to think about the document is this: it is a diagnosis, and everything downstream answers to it. The remediator’s scope, the notification filed with the state, the containment plan, and the clearance inspection at the end all trace back to the rooms, materials, and methods named in the protocol. If the protocol is thin or generic, the job it produces will be thin and generic too — and the clearance inspector will be judging the finished work against a vague standard. A precise protocol is not bureaucracy. It is the thing that keeps a contractor from deciding mid-job how much wall comes out.
Read it beside your own notes. You probably took photos before anything moved, and you probably remember exactly where the smell was strongest. If the protocol names the attic decking but you also photographed a stained bathroom ceiling, ask why the ceiling isn’t listed. If it calls for cutting out drywall without ever addressing what got the drywall wet, ask that too. The EPA’s guidance that wet materials dried within 24 to 48 hours usually do not grow mold is a helpful frame here: the scope should match the actual wet area and the actual timeline, not a blanket assumption about an entire room.
There is one more practical argument in the protocol’s favor. When two remediation companies bid against the same written protocol, they are bidding the same job. Without it, you are comparing proposals written to different assumptions — which is how a “cheaper” quote quietly excludes the drying or the HEPA filtration.
Quantities, Containment, and Clearance: The Sections That Decide the Job
For most homeowners, the numbers are where a protocol becomes genuinely readable. The document should say how much material is affected and where — not “affected drywall,” but which wall, which ceiling, roughly how many square feet. That measurement matters beyond tidiness. Texas treats 25 contiguous square feet as the line where licensed work begins; below it, you may clean it yourself or hire anyone, and at or above it, the licensed assessment-remediation-clearance sequence applies. The protocol’s figures tell you which side of that line your project sits on and give you a written record of the size of the affected area if questions come up later.
Containment gets its own careful read. The protocol should describe how the work area is sealed off from living space, how negative pressure and HEPA filtration are handled, and how dust and spores are kept from migrating through the house. Pay particular attention to anything involving the HVAC system. If mold may be in or near the air handler or the ducts, the EPA advises not running the system until it has been checked, and the protocol should reflect how that equipment is isolated and addressed — Texas has separate rules for mold work on HVAC systems.
Then read the clearance section first, even though it appears near the end. How will the job be judged complete? A visual inspection, plus any samples the protocol specifically calls for. A protocol that never defines clearance is the loudest warning sign in the whole document, because the assessment consultant is the one who returns before containment comes down, checks the work, confirms the water cause was actually fixed, and issues a written passed clearance report. If you landed on a company after typing mold remediation near me into a search bar, treat the protocol as the one document in the process written by someone who isn’t selling you the removal itself. It is your benchmark, and it is worth an hour of careful reading.
What to Request Before the Crew Arrives — and What You Keep Afterward
Before any company starts, ask for the Consumer Mold Information Sheet, proof of at least $1 million in liability insurance, and the written protocol. Then look the license up at tdlr.texas.gov. The remediation contractor’s work plan should mirror the protocol room by room and material by material; if it adds rooms nobody discussed or drops a section the consultant flagged, get that resolved in writing. Expect the contractor to notify TDLR at least five days before starting — the next business day in a water-damage emergency, with a $25 state fee — and understand that unlicensed assessment or remediation is a Class C violation carrying a $2,000 to $5,000 penalty per violation.
After clearance, the contractor has 10 days to give you a Certificate of Mold Damage Remediation (TDI form MDR-1) signed by both licensees. Keep that document somewhere you will find it years from now. Insurers may not underwrite against the remediated damage it documents, and buyers are entitled to copies for five years. If anyone in the home has breathing trouble or other symptoms, that is a conversation with a doctor rather than a remediator.
On cost, set expectations early: the assessment, the protocol, and the clearance are separate invoices from a separate company, so the remediation quote alone never tells the full story. Published national planning ranges from sources such as This Old House, Fixr, and HomeAdvisor are planning figures only — actual Plano quotes come from the individual companies after they have looked at the job. Plano Mold Experts is a free, no-obligation quote service that passes a single description of the problem to independent TDLR-licensed companies serving Plano, Frisco, McKinney, Allen, and nearby Collin County cities; it does not perform the work itself. Whichever companies contact you, the protocol in your hand is what you compare every work plan against.
