Mold remediation is the removal and cleanup of mold after the moisture problem is fixed. In Texas it is a different licensed role from mold assessment, and one license holder may not do both on the same project. At 25 contiguous square feet or more, remediation needs a licensed contractor working from an assessor's written protocol.
Mold is a moisture problem first and a cleanup problem second. It grows on materials that stay wet, so removing it without fixing the water source simply sets up the next round. If your house has had a leak, a wet ceiling or a flood, the first questions are where the water came from, whether it is stopped, and whether the materials have been dried.
Texas treats mold work differently from most states. It licenses mold assessors, who inspect and write the plan, and mold remediators, who carry the plan out, and it deliberately keeps them separate. This page is about the remediation role only. It does not offer testing or inspection, and nobody on this site will sell you the two together for the same job.
That separation is useful to know before you hire anyone. If a company offers to test your house and also remove what it finds, the law in Texas is the reason that should give you pause. The sections below explain how the rule works, where the 25-square-foot line sits, and what to ask for before work begins.
Do not cut into a moldy wall, run a fan across the growth, or scrub it dry. Disturbing it spreads spores through the house. Keep children and anyone with asthma out of the area, and call a professional for anything you cannot measure or reach.
No remediation holds if the water is still coming in. A plumber, A/C contractor or roofer fixes the source, and the structure is dried until the readings match a dry reference.
A licensed assessor inspects, sets the scope and writes the remediation protocol. That assessor is a separate company from the remediator. Below the line a written protocol is generally not required.
Plastic sheeting seals the work area, and HEPA-filtered air machines keep the air moving out of the room instead of into the rest of the house. This is the step that keeps spores from spreading while materials are disturbed.
Porous materials with growth, such as drywall and insulation, are cut out and bagged. Solid framing is cleaned with HEPA vacuums and damp wiping. Spraying bleach is not a substitute for removal.
Remaining surfaces are dried and checked with a moisture meter. On larger jobs the assessor returns for a clearance check, and the owner receives a certificate of mold damage remediation.
Remediation cost depends mostly on the size of the area, whether full containment is needed, and how much porous material has to be replaced. The assessor and the remediator are separate companies and are priced separately.
| Job | Typical range | What it includes |
|---|---|---|
| Small mold remediation, under 25 contiguous sq ft | $500–$2,000 | Containment, removal and cleaning of a limited area |
| Large mold remediation, over 25 contiguous sq ft, full containment | $3,000–$12,000+ | Attics are common; a separate assessor's fee is not included |
| Antimicrobial application, per sq ft | $0.50–$2.00 | Used after removal and cleaning, on the assessor's direction |
| Wet attic insulation removal and replacement, per sq ft | $1.50–$4.00 | Affected insulation is usually replaced |
| Drywall replacement: hang, tape, texture, paint, per sq ft | $3–$7 | Repairs are quoted after remediation and drying |

Texas Occupations Code Chapter 1958 says a license holder may not perform both mold assessment and mold remediation on the same project, and a person may not own an interest in both companies on the same job. The aim is to keep the inspector's findings independent of whoever profits from removal.
The rule is administered by the Texas Department of Licensing and Regulation, or TDLR. It came in about 2003, after a high-profile insurance case brought attention to conflicts of interest in the industry, and the point was to stop firms from inflating findings at inspection to win the cleanup work. Treat that as background, not settled history.
For you, the practical result is simple. On anything at or above the 25-square-foot line, expect two license holders: an assessor who writes the protocol and a remediator who follows it. A company that offers to test your house and remove what it finds in one package is offering something the statute does not allow on that kind of job.
Generally no. Texas does not require a license to remediate contamination affecting less than 25 contiguous square feet for the project, and a homeowner working on their own home is generally exempt. At 25 contiguous square feet or more, a licensed remediation contractor and a licensed assessor are required.
That does not mean small mold is nothing. The EPA says a patch under about 10 square feet can usually be cleaned by the homeowner, but you still need to fix the moisture, protect your lungs and bag the debris. If you are unsure of the size, measure the contiguous affected area, including what you cannot yet see behind a wall.
Hidden growth is the usual surprise. A stain on a ceiling can sit over a much larger damp area, which is why the question of size should be answered by an assessor and not by the person who would be paid to remove it. See mold inspection for what that role looks like.
Ask for the company's TDLR license number and verify it with TDLR, ask for the assessor's written protocol if the job is 25 contiguous square feet or more, and confirm that the assessor and the remediator are separate companies. Ask how containment works and who does the clearance check.
A reputable company will give you its number without fuss. This site does not claim any TDLR license of its own, and none of its pages should be read as one. Whoever does the work on your house should be able to show you theirs.
Also ask what happens after the removal. On larger jobs there is a clearance check by the assessor, and you should receive a certificate of mold damage remediation. Ask what repairs are included and what is quoted separately, since new drywall and insulation are priced after remediation and drying.
Fast drying lowers the risk, but it is not a guarantee. The EPA advises drying water-damaged materials within 24 to 48 hours, and that is a guideline, not a deadline. Mold can start in a wet cavity before the surface looks wet, and may exist even when materials later dried.
Humid summers in North Texas can slow drying, and an attic that stays hot and damp is a good place for growth to start after a roof or condensate leak. If a leak sat for days or weeks, an assessment is worth the cost, whether or not you can smell or see anything. The guide on mold after water damage in Texas walks through the sequence.
Texas does not require a license to remediate less than 25 contiguous square feet, and a homeowner working on their own house is generally exempt. A crew can still do the cleanup, and it should follow the same containment and drying steps as a larger job.
This is licensed work. A licensed mold remediation contractor carries out a protocol written by a licensed assessor, and a clearance check follows. Attics are a common location for these jobs.
In Mansfield and the south metroplex, mold usually follows a specific kind of water: an attic water heater or air handler that leaked into insulation, a clogged condensate line during a long cooling season, a roof opened by hail, or a slab leak that dampened baseboards. The pages on water heater leak cleanup and AC condensate leak water damage cover those causes.
Texas humidity can stretch drying times, and a drying job that is stopped too early, or never monitored, is a common reason a repair has to be reopened later. Ask the crew to show you the moisture readings before the walls are closed.
Ask your insurer how your policy treats mold before you start, because coverage is often limited and is decided by the insurer. Texas also has consumer help through the Texas Department of Insurance and the Office of Public Insurance Counsel if you have a question about a claim.

In Texas, mold assessment and mold remediation are licensed by TDLR and must be done by two different license holders on the same project.
Not on a project at or above 25 contiguous square feet. Texas licenses assessors and remediators separately, and one license holder may not do both on the same project. That is why this page covers removal only and the inspection is a different role with a different company.
Mold can trigger allergy and asthma symptoms in some people, and the CDC calls the term toxic mold inaccurate. Color does not tell you what kind of mold it is, and it is not a reason to panic. Fix the moisture, and have the size and extent of the growth assessed.
It depends on the cause of the moisture and on the policy, and many policies limit mold coverage. Your insurer decides. Read your policy or ask your agent, and keep the photos and moisture readings from the water loss.
Small jobs are often done in a day or two, and larger jobs with full containment take longer, plus the time for drying and a clearance check. The crew should give you a plan and a rough scope before starting, not a promise about days.
Not on porous materials like drywall or insulation, where the roots go below the surface. Removal and HEPA cleaning are the usual methods. Bleach also mixes dangerously with other cleaners, so it is not a general fix.
A licensed plumber, A/C contractor or roofer, depending on the source. The crew handles drying and cleanup, and remediation, but not plumbing or roof repair. Without the leak fixed, any remediation can fail.
