Mold Remediation Cost in Texas (2026): What You'll Pay

Two widely used cost guides give somewhat different averages, mostly because they draw on different job data:

The per-square-foot figure is the most useful number for a quick estimate. At $10 to $30 per square foot, a 100-square-foot problem lands around $1,000 to $3,000, and a 500-square-foot problem around $5,000 to $15,000.

Where the mold is matters as much as how much there is. Attics, crawl spaces and HVAC systems cost more because they are hard to reach and hard to contain.

Price of mold removal by location

A few notes on these rooms:

• Bathrooms are cheap when the mold is on tile or caulk, and expensive when it has spread behind a tub or vanity. Fixr notes that hidden mold behind tubs, sinks or vanities raises costs significantly.
• Attics often involve insulation and roof decking. Fixr lists mold in attic insulation or ducts as a major cost driver.
• Crawl spaces are common in older Texas homes on pier-and-beam foundations. Bob Vila notes that crawl space work takes longer and costs more in labor.
• Whole-house jobs usually follow flooding or a long-running leak, and often include rebuilding walls and floors.

If you are wondering how much mold removal can cost at the high end, the answer is "a lot," and nearly all of it comes from a handful of factors.

Labor is most of the bill. Both guides estimate that labor is about 60% of a remediation job and materials about 40%. Containment, careful removal and cleanup are slow work.

Containment and air cleaning. Fixr lists containment at $75 to $120 per hour, and air scrubbers and HEPA vacuums starting at $500 to $1,000. In Texas, a licensed contractor must use containment when the job affects 25 contiguous square feet or more, so bigger jobs carry this cost by rule.

Removing porous materials. The EPA says moldy porous materials may have to be discarded, and TDLR says drywall, carpet and insulation with mold growth should be removed and discarded. Fixr puts disposal and cleaning of soft items at $2 to $20 per pound.

Rebuilding after removal. Remediation companies remove; they don't always rebuild. Fixr estimates restoration in severe cases at $10,000 to $20,000. Ask every company whether drywall, paint and flooring replacement are in the quote.

Fixing the water source. The EPA is clear that cleaning mold without fixing the moisture problem usually lets it come back. That repair is a separate cost: Fixr lists leak repair at $150 to $350 and roof leak repair at $400 to $2,500.

Mold type matters less than you'd think. Cost guides do list prices by species, but the spread is narrow: Fixr shows $600 to $5,000 for Chaetomium and $800 to $7,000 for black mold (Stachybotrys). Size and location drive the price, not color.

This is the part many quotes leave out. In Texas, a licensed mold remediation contractor hired by a consumer must work from a protocol developed by a licensed Mold Assessment Consultant, and the project isn't finished until a consultant does a post-remediation assessment. So most licensed jobs involve two companies and two bills.

Extra costs to budget beyond the removal quote

None of the cost guides we could reach gives a standalone price for the protocol or for clearance testing, so ask the assessor to quote both up front. For more detail, see our guides to mold testing cost and mold clearance testing.

Texas law says a license holder may not perform both mold assessment and mold remediation on the same project, and no one may own an interest in both the testing firm and the removal firm on the same job. The point is simple: the company that profits from the cleanup shouldn't be the one deciding how big the problem is, or whether the cleanup passed.

That rule shapes how you shop. Cost guides note that some companies waive or bundle the inspection if you hire them for removal, and Bob Vila notes that testing is often offered by remediation companies. In Texas, a "free inspection" from the company that will also do your removal is a red flag on a licensed job. Hire a mold testing company first, then get removal bids from separate mold removal companies. Our guide on why testing and removal are different companies explains the rule in full.

Sometimes. The Texas Department of Insurance says most home policies cover sudden and accidental water damage, and if mold develops on a damaged item, it would be covered. But:

• Policies usually won't cover damage from gradual leaks, including resulting mold.
• Mold from a flood would not be covered by a home policy, because home policies don't cover floods.
• Most home policies don't include mold cleanup and testing after a damaged item is removed, though your insurer may let you add coverage.
• FEMA says National Flood Insurance Program policies will not cover damage from mold, though FEMA disaster aid may help when mold makes a home unlivable.

There is one Texas benefit worth paying for: the Certificate of Mold Damage Remediation. If you hold a certificate showing the underlying cause was fixed, an insurer may not make an underwriting decision based on previous mold damage or claims. You also must give buyers a copy of each certificate from the past five years when you sell. See does insurance cover mold for more.

• Small jobs can be DIY. A homeowner can clean up mold in the home without a license, and the EPA says areas under about 10 square feet can usually be handled yourself. The catch: only a licensed remediator can issue a Certificate of Mold Damage Remediation.
• Bigger jobs carry more paperwork. For 25 contiguous square feet or more, the contractor must notify TDLR at least five calendar days before starting, except in a water-damage emergency.
• Floods and hurricanes. After a flood, Texas A&M AgriLife advises opening flooded walls and says drying can take a few weeks to a month, with flooded drywall and wet insulation discarded. That is why post-storm jobs on the Gulf Coast, in Houston and Corpus Christi, tend to land at the high end of the ranges above. See mold after a flood in Texas.
• Humidity. The EPA recommends keeping indoor humidity below 60 percent, ideally 30 to 50 percent. In humid parts of Texas, a dehumidifier after remediation helps protect what you paid for.

You can't know what a job "should" cost until someone measures it. Here is how to get comparable bids:

1. Start with the protocol. Have a licensed assessor write the remediation protocol. It must list the rooms, estimated quantities of material, methods, containment and clearance criteria. Give the same protocol to every removal company, so all quotes cover the same work.
2. Get two or three bids from licensed removal companies. Check each license with our license check tool or TDLR. Every company in our directory is checked daily; see how we verify.
3. Ask what's included. Bob Vila suggests asking whether testing before and after remediation is included, how long the job takes, and whether you can stay home. Also ask about rebuild work and disposal fees.
4. Ask for proof of insurance. Texas rules require licensees to carry commercial general liability insurance of at least $1 million, or be self-insured.
5. Confirm you'll get the certificate. The contractor must give you before-and-after photos and the Certificate of Mold Damage Remediation within ten calendar days after the project stop date.
