What Is a TDLR Mold Remediation License in Texas?

A TDLR mold remediation license is a credential issued by the Texas Department of Licensing and Regulation that authorizes a person or company to perform mold assessment or mold cleanup work for pay in Texas. It exists because the state legislature decided mold work involves enough health and property risk that practitioners should meet training, testing, and insurance standards before touching a customer's home. The program is set up under Texas Occupations Code Chapter 1958 and administered day-to-day by TDLR.

What does the TDLR mold program actually regulate?

TDLR's mold program covers two distinct kinds of work: assessment (inspecting, testing, and writing a remediation protocol) and remediation (physically removing or treating mold-damaged materials). These are treated as separate professions with separate licenses, and a company or technician generally cannot perform both roles on the same job — a licensed assessor is supposed to be independent from the crew doing the cleanup, so the person grading the work isn't the same person who did it.

What are the different TDLR mold license types?

Texas Occupations Code Chapter 1958 and its implementing rules at 16 TAC Chapter 78 establish four license categories:

• Mold Assessment Consultant — inspects properties, performs or oversees testing, and writes the mold remediation protocol a contractor must follow.
• Mold Assessment Technician — works under a consultant, collecting samples and performing inspection tasks.
• Mold Remediation Contractor — runs and takes legal responsibility for a remediation job, including issuing the required completion certificate.
• Mold Remediation Worker — performs hands-on cleanup labor under a licensed contractor's supervision.

Each license type has its own education, training, and experience prerequisites set by TDLR rule, and each has a defined, limited scope of work — a worker license, for example, doesn't authorize someone to run a job or sign off on it.

Who is legally required to hold a TDLR mold license?

As a general rule, anyone performing mold assessment or mold remediation work in Texas for compensation must hold the applicable license. This applies to individual technicians as well as the business entity performing the work. It's meant to prevent unlicensed, uninsured operators from doing testing or cleanup that affects a family's health or a home's structure.

Is there an exemption for small mold jobs?

Yes. Texas law carves out a de minimis exemption for remediation of a small, contiguous area of mold-damaged material — commonly cited around 25 square feet or less — and for certain work an owner-occupant performs on their own residence. Because exemption thresholds and wording are the kind of detail lawmakers periodically revisit, homeowners and contractors should confirm the current exact language directly through TDLR's mold program page or the statute text rather than relying on secondhand summaries, including this one, for a borderline-sized job.

What is a Certificate of Mold Damage Remediation?

When a licensed Mold Remediation Contractor completes a job above the exempt threshold, Texas law requires the contractor to give the property owner a document called a Certificate of Mold Damage Remediation. This certificate states that the remediation work met the post-remediation clearance criteria set out in the assessment protocol — essentially, an official sign-off that the mold problem addressed by the job has been remediated to the standard the assessor specified. Homeowners should keep this certificate; it can matter for future real estate transactions, insurance claims, or disputes.

Do licensed mold remediation contractors have to carry insurance?

Mold Remediation Contractors are generally required to maintain liability insurance as a condition of holding a TDLR license. This is intended to give homeowners financial recourse if a remediation job is done improperly and causes further property damage. Minimum coverage amounts are set by TDLR rule and can be updated, so if insurance coverage matters to your decision — for example, on a large or structurally complex job — ask the contractor for proof of current coverage and verify licensing status through TDLR directly rather than relying on a business card or website claim.

How often does a TDLR mold license need to be renewed?

TDLR mold licenses are issued on a renewal cycle (commonly two years) and renewal typically requires completing continuing education. This is meant to keep licensees current on protocols, safety practices, and any regulatory changes. Exact CE hour requirements are set by rule and can change, so check the current requirements on TDLR's site if you're a licensee planning your renewal timeline.

How much does mold remediation cost in Texas?

Cost depends heavily on the size of the affected area, the type of material involved (drywall, insulation, flooring, HVAC components), accessibility, and whether the underlying moisture source has already been fixed. There isn't a single statewide rate, and homeowners should expect meaningful variation between a small, contained bathroom job and a large-scale job involving structural drying, containment, and air scrubbing. Because pricing changes with market conditions and project scope, the most reliable way to budget is to get written, itemized quotes from more than one licensed contractor rather than relying on a generic national average. You can start that process through the Texas mold remediation directory.

Does Texas homeowners insurance cover mold damage?

Texas homeowners policies commonly limit mold-related coverage to a lower sublimit unless the policyholder has purchased an additional mold endorsement, and coverage often hinges on whether the mold resulted from a
