If you’ve found mold in your home, the first question is almost always the same: what is this going to cost me? The honest answer is that it depends on how much mold there is and where it’s hiding — but you can walk into a quote knowing the typical ranges and what moves them.
The short answer
In 2026, most Texas mold remediation projects fall between $500 and $6,000, with the average job landing somewhere around $2,000–$3,500. Priced by area, professionals across Texas generally charge $10 to $25 per square foot of affected space. A single closet or small bathroom sits at the low end; mold that has spread through multiple rooms or behind walls climbs quickly from there.
Typical price ranges by project size
Size is the biggest driver. Here’s how DFW-area jobs commonly break down:
| Affected area | Typical cost | Example |
|---|---|---|
| Small (up to ~25 sq ft) | $500 – $2,000 | One closet, a small bathroom wall, under a sink |
| Medium (25 – 100 sq ft) | $2,000 – $6,000 | A full bathroom, a bedroom, sections behind drywall |
| Large (100+ sq ft) | $6,000 – $15,000+ | Multiple rooms, HVAC system, whole-home spread |
Severe cases — mold throughout a home, extensive structural involvement, or contamination inside the HVAC system — can run higher still once demolition and rebuild are added.
What drives the price up or down
Two homes with the same square footage of mold can get very different quotes. The factors that matter most:
- Where the mold is. Surface mold on drywall is cheaper than mold behind walls, under flooring, in a crawl space, or inside ductwork, which requires more demolition and reconstruction.
- The cause. If a plumbing leak, slab leak, or roof intrusion is feeding the mold, that source has to be fixed too — or the mold comes back.
- Reconstruction. Removal is only half the job. Replacing drywall, flooring, or trim that had to be torn out adds to the total.
- Testing and clearance. Independent testing before and after confirms the problem is gone — a small added cost that protects you at resale or with an insurer.
The Texas 25-square-foot rule
Texas regulates mold work through the Department of Licensing and Regulation (TDLR). Once a project involves 25 contiguous square feet or more of mold, it must be handled by licensed professionals. Texas rules also keep the inspector and the remediator independent on larger jobs — the company that assesses and clears the work generally can’t be the same one doing certain remediation steps. It’s worth asking any company how they handle licensing and clearance before you sign.
Does insurance cover it?
Sometimes. Homeowner policies often cover mold when it results from a “sudden and accidental” covered event — a burst pipe, for example — but typically exclude mold caused by long-term leaks or deferred maintenance. Documentation matters: photos, the source of the water, and professional testing all help a claim. Read your policy’s mold provisions before you assume either way.
Why the cheapest quote isn’t always the win
Mold remediation done poorly is money spent twice. A low bid that skips finding the moisture source, cuts containment, or never re-tests can leave you with mold that returns in months. The value is in doing it once, correctly — with the source fixed, the area contained, and clearance testing to prove it worked.
