How much does mold remediation cost in Texas?
There is no Texas price list, and no one can tell you what your job costs without seeing it. What changes the number:
- Square footage. The biggest factor. What you see on the surface is often smaller than what turns up behind drywall, cabinets or baseboards once the wall is opened.
- Where it is in the house. An open bathroom wall is quicker than a low attic in August, a closet air handler or a condo unit where the crew has to protect shared hallways.
- HVAC involvement. Mold in an air handler or ductwork runs $3,000 to $10,000 in the published ranges, and repairing the AC itself is a separate trade.
- Materials removed. Framing, concrete and other hard surfaces can often be cleaned. Moldy drywall, insulation, carpet and pad usually have to be cut out, bagged and hauled away.
- Containment. Larger jobs need plastic walls, a sealed doorway and air filtration so spores don't drift into the rest of the home. More rooms means more setup.
- Assessor and clearance fees. On a licensed job of 25 or more contiguous square feet, a separate licensed assessor writes the protocol and later checks the work. That is a second bill. A standalone inspection runs about $450 to $800 (Fixr, Jan 2025).
- TDLR notification. TDLR lists a $25 fee for notification of an owner-occupied residential remediation, filed by the licensed remediator.
- Rebuild. New drywall, paint, flooring and trim are usually a separate contract with a different trade.
- Permits. Mold cleanup itself usually isn't permitted work, but rebuilding often is. In the City of Corpus Christi, including Flour Bluff and Padre Island, interior remodeling, roofing and foundation repairs use Form 1003, plus an elevation certificate in a floodplain. Coastal rebuilds may need a TDI windstorm (WPI-8) inspection. In other towns, check with your city building department.
- After a big storm. When many homes need work at once, schedules and prices may shift. This is a general pattern, not a measured local figure, so get more than one written quote.

The pieces of a Texas mold budget
A licensed Corpus Christi mold job can have up to four separate pieces. Smaller jobs under 25 contiguous square feet often need only the second one.
Assessment and protocol
A licensed mold assessment consultant inspects, may take samples, and writes a remediation protocol for the job.
Remediation
A licensed remediation company, separate from the assessor, writes a work plan, notifies TDLR, sets up containment, removes and cleans the mold, and dries the area.
Clearance and certificate
The assessor checks the finished work. Within 10 days, the remediator provides the Certificate of Mold Damage Remediation (TDI form MDR-1).
Rebuild
Drywall, paint and finishes by other trades, with any permit or windstorm inspection the work requires.
Texas rules that affect the price
Texas requires TDLR licenses for mold assessment and remediation work on 25 or more contiguous square feet (Occ. Code §1958.101–.102). Verify any company at tdlr.texas.gov/LicenseSearch. Not every company that replies will hold a license, so check each one yourself.
In Texas, the company that assesses your mold and writes the protocol cannot be the company that removes it on the same project, and one owner can't hold both (Occ. Code §1958.155).
Under 25 contiguous square feet, a homeowner can clean it themselves or hire anyone. At 25 sq ft or more, hired work needs licensed companies, a written protocol, a work plan, TDLR notification (5 days ahead, or the next business day in a water-damage emergency), a clearance assessment, and a Certificate of Mold Damage Remediation within 10 days. Owners of residential property with fewer than 10 units may be exempt at any size for their own property (§1958.102(e)); confirm with TDLR before relying on it.
Ask for the Certificate of Mold Damage Remediation (TDI form MDR-1). Insurers can't make underwriting decisions based on remediated mold damage when you have it (Ins. Code §544.303), and you must give buyers copies from the last five years (§1958.154(b)).
Will insurance pay for it?
The Texas Department of Insurance says most home policies cover a sudden and accidental release of water, but not a continuous leak, and won't cover mold removal except to repair damage caused by a covered risk. Mold removal can be an optional endorsement. Many policies cap or exclude mold; check your declarations page.
On the Coastal Bend, wind and hail may be covered by the Texas Windstorm Insurance Association (TWIA) rather than your home policy, and flood needs a separate flood policy, which TDI says usually has a 30-day waiting period. Mold coverage, if any, follows the cause of the water. Photograph everything before tear-out and call your insurer before you sign a remediation contract. No one, including this site or the companies that reply, can promise what a policy will pay. More on mold after hurricanes and floods.
What to ask each company for
- TDLR license numbers for both the assessor and the remediator. Look them up yourself.
- The protocol and the work plan in writing, listing the rooms, containment, what will be removed and how drying will be checked.
- How clearance works and whether the assessor's fee includes it.
- The Certificate of Mold Damage Remediation when the job is done.
- Photos and paperwork you can give your insurer.
If the mold is in an attic or an air handler or ducts, those pages explain what the job usually involves, and mold removal covers the full remediation process.
Mold cost questions
How much does mold remediation cost per square foot?
Published national guides put it at $10 to $25 per square foot of affected area (This Old House, Mar 2026) or $10 to $30 (Fixr, Aug 2025). So 100 square feet of moldy drywall often prices near $1,000 to $2,500 before assessment, AC work or rebuild. Corpus Christi quotes vary with access, materials and how far the water spread.
How much does a mold inspection cost in Corpus Christi?
Fixr's January 2025 national figures put a standalone mold inspection with testing at $450 to $800, with an average near $500. An inspection alone runs about $300 to $600, an air test about $500 to $700, and a tape or swab surface test about $150 to $200. No current Corpus Christi-specific testing price survey was found.
Why might I pay two companies in Texas?
Because in Texas, the company that assesses your mold and writes the protocol cannot be the company that removes it on the same project, and one owner can't hold both (Occ. Code §1958.155). On a licensed job of 25 or more contiguous square feet, the assessor's fee and the remediator's fee are separate lines in your budget.
Why do mold quotes vary so much?
Companies may be quoting different jobs. One may include containment, removal, drying and rebuild; another may leave out rebuild or assume less hidden damage. Mold behind drywall, a hot attic, an air handler or a whole flooded floor all change the price. Ask each remediator for a written work plan that follows the assessor's protocol, so you can compare line by line.
Does insurance pay for mold remediation in Texas?
Sometimes. TDI says most home policies won't cover mold removal, except to repair damage caused by a covered risk, and that mold removal coverage can be added as an optional endorsement. Many policies cap or exclude mold; check your declarations page. On the coast, wind may be under TWIA and flood under a separate policy. No one can promise coverage.
