Most local mold searches begin the same way: a dark patch on a bathroom ceiling, a musty smell with no visible leak, or staining on attic decking that nobody noticed until now. Your instinct is to find a crew nearby. In Texas, the smarter first move is to understand the structure the law requires, because that structure tells you exactly what a legitimate quote should contain — and what a vague one is quietly leaving out. Under Occupations Code chapter 1958, mold assessment and mold remediation are two separate licensed activities, both overseen by the Texas Department of Licensing and Regulation (TDLR), and the same company may not perform both on your project. That single rule reframes everything. You are not shopping for one crew; you are comparing a coordinated pair of services.
The first half is the assessment. A TDLR-licensed mold assessment consultant inspects the property, maps moisture to find where the water is actually coming from, decides whether samples are even necessary, and writes a project-specific remediation protocol. That protocol spells out which rooms are involved, how much material comes out, what methods are used, how containment is built, and how the job will be judged as clear. You are entitled to that written protocol at least one day before work begins, which gives you time to read it and compare it against other scopes you have received.
The second half is remediation, performed by a different licensed company. That contractor writes a work plan to carry out the protocol — not a plan of its own invention — and notifies TDLR at least five days before starting, or by the next business day when a water-damage emergency is involved. From there the work typically involves containment, HEPA filtration, removal of moldy drywall and insulation, and drying. The assessor then returns before containment comes down, checks the work visually, takes any samples the protocol called for, confirms the water source was corrected, and issues a written passed clearance.
Within 10 days of completion, the remediation contractor provides a Certificate of Mold Damage Remediation (TDI form MDR-1) signed by both licensees. Keep that document. Insurers may not underwrite against the remediated damage it documents, and buyers are entitled to copies for five years. Before any company starts, ask for the Consumer Mold Information Sheet and proof of at least $1 million in liability insurance.
Checkpoints to Verify Before You Book Anyone
Start with size, because size decides which rules apply. Texas treats 25 contiguous square feet of mold as the line where licensed work begins. Below that threshold you may clean it yourself or hire anyone you like. At or above it, hired work has to follow the licensed sequence described above — assessment, protocol, remediation, clearance, certificate. If a company quotes the job without ever mentioning an assessment protocol, that is your first sign something is off, particularly on a larger patch.
Verification is quick and free. Look up every license at tdlr.texas.gov/LicenseSearch before money changes hands, and confirm the company name on the quote matches the name on the license. Unlicensed assessment or remediation is a Class C violation carrying a $2,000 to $5,000 penalty per violation, which tells you how seriously the state treats it. Ask the remediation contractor when the TDLR notification was filed, and expect a $25 fee to appear in the paperwork. Ask who is performing clearance, and be suspicious if the answer is the same company that removed the material.
Read the quote for what is excluded. Assessment, the written protocol, and clearance are separate invoices from a separate company, so a single all-in price that bundles everything deserves closer scrutiny. On cost generally, published national planning ranges from sources such as This Old House, Fixr, and HomeAdvisor give rough ballpark context, but they are planning benchmarks, not real numbers for your house — actual quotes come from the companies after they look at the job.
Meanwhile, protect the evidence. Stop the water if you can do it safely, and remember the EPA’s guidance that wet materials dried within 24 to 48 hours usually do not grow mold. Do not scrub, sand, or bleach a large area; disturbing a big patch spreads spores, and TDLR notes that bleach without fixing the water is not a lasting fix. Photograph the original condition with the date you found it, keep children and pets out, and if the mold may be in or near the air handler or ducts, the EPA advises against running the system until it has been checked.
Local Conditions Change the Scope and the Quote
Plano and the surrounding Collin County suburbs produce a fairly predictable set of mold scenarios, and each one changes what belongs in a scope of work. Slab leaks on Blackland clay push moisture up through flooring and baseboards, sometimes without an obvious puddle. Hail-bruised roofs let water into attic decking months before anyone climbs up to look. Attic air handlers and condensate lines drip onto ceilings below, and bath fans venting into the attic rather than outdoors keep the space humid year-round. A quote written for a shower ceiling is not the same document as a quote for a slab leak, and the protocol should reflect the actual water source.
HVAC work is its own category. Moldy coils, drain pans, and ducts in a system that runs for months at a stretch fall under separate Texas rules for mold work on HVAC systems, which is one reason a general remediation quote may not cover duct cleaning or coil treatment. Renters and owners of apartments or condos have additional considerations, including rights under Property Code 92.052 and a separate 10-unit licensing rule that applies to property owners doing their own work. If anyone in the home has breathing trouble or other symptoms, that is a conversation for a doctor — a contractor cannot answer it.
Practically, the fastest path is to describe the problem once: where the mold is, roughly how big it looks, what got wet and when, the age of the house, and whether it is a house, apartment, or business. Requests are routed to independent, TDLR-licensed assessment and remediation companies serving Plano, Frisco, McKinney, Allen, Richardson, Wylie, Murphy, The Colony, Carrollton, and nearby ZIP codes, and those companies contact you directly with no obligation. That is what a well-built search for mold remediation near me should really return — not a single crew promising everything, but separate licensed companies, a written protocol, a passed clearance, and a certificate you can hand to an insurer or a buyer.
