Mold Removal Contractors in Houston, TX

Houston's humidity and rainfall create ideal conditions for mold growth, and your home's age makes it particularly vulnerable. The median Houston home was built in 1979, meaning most houses have crawlspaces, attics, and foundations that have weathered decades of the city's 75% average humidity and 50 inches of annual rainfall. Older homes weren't built with today's moisture barriers, so water intrusion through foundations, roof leaks, and poor drainage accumulate over time. Combined with Houston's heat, this creates perfect conditions for mold to thrive in hidden spaces before you ever see it.

Mold remediation projects in Houston typically cost between $1,500 and $4,500, depending mainly on how much of your home is affected and whether structural materials need replacement. A small bathroom or attic problem sits at the lower end. Larger jobs involving crawlspace treatment, multiple rooms, or structural damage push toward the higher range. Getting quotes from multiple contractors will help you understand what's actually needed versus what's being oversold.

Texas requires all mold remediation contractors to hold a Texas Mold Remediation Contractor License from the Texas Department of Licensing and Regulation (TDLR). Before you hire anyone, verify their license status at tdlr.texas.gov. This isn't optional, and it's your main protection against unlicensed work. You'll find 42 licensed contractors listed here for Houston, so you have real options.

One thing specific to Houston: don't assume a mold problem is just cosmetic. Our climate means what looks like surface mold often signals moisture problems deeper in your walls or foundation. Get a proper inspection before accepting any contractor's initial estimate.
