Why a Licensed Contractor Isn't Optional in Texas
Texas has some of the strictest mold remediation laws in the country. Here's what's at stake if the contractor you hire isn't TDLR-licensed when a license is required.
There's a Document Your Contractor Is Required to Give You
Most Texas homeowners have never heard of a Certificate of Mold Damage Remediation (CMDR). Under Texas Occupations Code §1958.154, a licensed Mold Assessment Consultant who did not perform the remediation generally issues the certificate after a post-remediation assessment — so the assessor and remediator are usually different licensees (§1958.155). Licensing rules do not apply to every job: work under 25 contiguous square feet, certain owner/tenant work, and an owner's residential property with fewer than 10 dwelling units under §1958.102(e) (see also TDLR consumer guidance). Separately, SB 1255 (eff. Sept. 1, 2025) repealed the old supervised-employee exemption in §1958.102(b) — it did not create the under-10-units rule. Without a CMDR when one is required, selling within five years is harder — sellers must provide CMDRs issued in the five years before the sale (§1958.154(b)).
A CMDR Protects You With Insurers — and Limits Liability
Texas Insurance Code §544.303 generally bars insurers from using prior mold damage against you in underwriting when you have a CMDR (or an independent inspection showing no mold). Separately, Occupations Code §1958.303 provides a liability shield for property owners who hold a certificate. Hiring an unlicensed firm for work that requires a license can still create claim and compliance problems — verify status in the TDLR License Search and review TDLR's mold FAQ before you hire.
No CMDR Can Derail a Sale — and Non-Disclosure Can Get Expensive
Texas law requires sellers to provide buyers with Certificates of Mold Damage Remediation issued during the five years preceding the sale (§1958.154(b)). Missing paperwork can delay or kill a deal. Separately, under the Texas Deceptive Trade Practices Act (§17.50), knowing or intentional non-disclosure of material defects can expose a seller to damages — potentially up to three times economic damages in some cases. This is general information, not legal advice; confirm details with a licensed professional and current statutes.

What TDLR-Licensed Mold Professionals Typically Handle
This site is an independent license directory and education resource — not a remediation contractor. The topics below describe work licensed assessors and remediators commonly perform in Texas. Always verify a TDLR license before you hire. Counts and refresh rules are explained in our methodology.
Black Mold Removal
Black mold (Stachybotrys chartarum) usually needs professional containment and should not be disturbed without proper equipment. TDLR-licensed remediators typically use negative air pressure, HEPA filtration, and full PPE when removing it.
Water-Related Mold Response
EPA advises drying wet materials within 24–48 hours because mold can begin growing that quickly on damp surfaces. TDLR-licensed remediators typically prioritize containment and moisture control after leaks, floods, or storms — this directory does not provide emergency response.
Water Damage & Mold Remediation
Water damage left unaddressed often leads to mold behind walls and under flooring. Licensed contractors may handle water extraction and mold remediation in one coordinated scope of work.
Mold Inspection & Testing
A licensed Mold Assessment Consultant can identify visible and hidden growth, moisture sources, and air-quality issues, and deliver a written assessment that meets Texas requirements.
Attic Mold Remediation
Texas attics are common mold sites because of heat, poor ventilation, and roof leaks. Licensed remediators typically find the moisture source, remove contaminated material, and correct ventilation to reduce recurrence.
Crawl Space Mold Remediation
Crawl spaces under Texas homes often collect ground moisture and standing water after heavy rains. Licensed work may include remediation, vapor barriers, and longer-term moisture control.
HVAC & Air Duct Mold Removal
Year-round air conditioning makes HVAC units and ductwork frequent mold sites. Licensed professionals may clean and treat air handlers, evaporator coils, and ductwork so mold is less likely to circulate.
Bathroom Mold Removal
Bathrooms are among the most common household mold sites due to chronic moisture and weak ventilation. Licensed remediators often address grout, drywall, subfloor, and ceilings — and the underlying moisture problem.
Basement Mold Removal
Where Texas homes have basements, groundwater and humidity raise mold risk. Licensed contractors typically use containment, removal, and post-remediation testing consistent with industry protocols such as IICRC S520.
Commercial Mold Remediation
Commercial jobs need careful documentation and limited business disruption. Licensed contractors handle offices, retail, warehouses, and multi-unit residential properties under written protocols.
Real Estate Mold Inspection
Mold findings during Texas transactions can delay or kill deals. TDLR-licensed Mold Assessment Consultants can produce inspection reports suitable for buyers, sellers, and lenders — with turnaround negotiated case by case.
Post-Remediation Clearance Testing
After remediation, clearance testing checks whether mold levels are acceptable. Texas law requires this testing to be done by a licensed Mold Assessment Consultant who is independent from the remediating contractor.
Rental Property Mold Work
Landlords and property managers often need licensed assessment and remediation plus documentation for habitability and insurance. Always verify the TDLR license and keep paperwork for future sales or claims.
Mold Prevention & Treatment
Preventive work may include moisture control, ventilation fixes, and — where appropriate — antimicrobial treatments on high-risk surfaces. A licensed assessor or remediator can advise what fits the building’s conditions.
Every licensed remediation project should end with a Certificate of Mold Damage Remediation (CMDR) — keep it for insurance and for any sale within five years.
