Mold Removal Contractors in San Antonio, TX

San Antonio's combination of high humidity (66% average) and older housing stock (median home built in 1981) creates a specific mold problem: homes built four decades ago often have aging moisture barriers, outdated ventilation, and foundation issues that let humidity seep in year-round. With 32 inches of annual rainfall, water intrusion through roofs, walls, and crawlspaces compounds the issue. The result is that mold in San Antonio tends to hide in structural cavities and attics rather than appearing as obvious surface growth, which means problems often go unnoticed until they're substantial.

Mold remediation projects in San Antonio typically run between $1,200 and $3,800. The cost depends on how much area needs treatment, whether structural drying is required, and whether the contractor needs to remove contaminated materials like drywall or insulation. A small bathroom mold spot costs far less than a crawlspace remediation in a 1980s home.

Texas requires all mold remediation contractors to hold a license from the Texas Department of Licensing and Regulation (TDLR). Before hiring anyone from this list of 48 contractors, verify their license status directly at tdlr.texas.gov. This isn't optional - it's a legal requirement that protects you.

One critical detail for San Antonio specifically: get a moisture assessment alongside any mold estimate. The humidity here means remediation alone won't stick if the source (usually poor ventilation or a slow leak) isn't fixed. Contractors who skip this step are setting you up for the mold to return within months.
