Small mold jobs in Houston, such as a section of bathroom wall or a closet, often cost in the low thousands of dollars, while whole-house remediation after a flood can run well into five figures. The size of the affected area, where the mold is and Texas’s rules on independent assessment all shape the price.

Why Texas Rules Affect Cost
Texas licenses mold assessors and remediators through TDLR. For projects of 25 contiguous square feet or more, a licensed assessor must write a remediation protocol and the remediator must be a separate company. You pay for the assessment and a post-remediation clearance test in addition to the remediation itself, but it protects you from a contractor who both finds and profits from the problem.
What Drives The Price
Square footage and number of rooms affected
Access: attics, crawlspaces and inside walls cost more
Containment and HEPA air scrubbing needed
Materials to remove and replace, such as drywall, insulation and flooring
Fixing the moisture source, such as a leak or AC condensate line
Will Insurance Pay?
Homeowners policies often cover mold that results from a sudden covered event, such as a burst pipe, but many cap mold coverage or exclude mold from long-term leaks and humidity. Flood-related mold falls under flood insurance. Read your policy and document the water event.
Conclusion
Budget for an independent assessment, the remediation itself and clearance testing, and always fix the moisture source so you only pay once.
