How Much Does Mold Removal Cost Per Square Foot in Texas?

Mold removal in Texas typically costs $10 to $25 per square foot, with most contractors charging a minimum service fee of $500 to $1,500 for small jobs. Larger projects — whole attics, crawlspaces, or flood-damaged homes — commonly range from $10,000 to $30,000 or more once contaminated drywall, insulation, and subflooring have to be removed and replaced. The final number depends heavily on the size of the affected area, the mold species involved, and whether structural materials need demolition.

Because pricing varies so much by job type, it's worth understanding what actually drives the cost before you request quotes — and what Texas law requires for larger remediation projects.

What's a typical price range for mold removal in Texas?

Small, contained jobs — a single bathroom ceiling or a closet wall — often fall at the lower end of the $10–$25 per square foot range, or may be billed as a flat minimum charge regardless of square footage. Larger jobs involving whole-house contamination, HVAC systems, or post-flood remediation push costs toward the higher end, partly because of containment setup, negative air pressure equipment, and disposal of porous materials. Humid Gulf Coast metros like Houston, and areas with recurring flood exposure, tend to see more frequent remediation demand, which can affect contractor availability and pricing, especially after major storms.

What actually drives the per-square-foot price?

• Size and extent of contamination — larger or more spread-out mold growth increases labor and material costs.
• Mold type — toxigenic species such as Stachybotrys (
