Mold Removal Contractors in Chattanooga, TN

Chattanooga's combination of high humidity (averaging 73%) and older housing stock (median home built in 1974) creates a perfect setup for mold. Homes built in the mid-1970s often have crawlspaces and basement areas that weren't sealed or ventilated to modern standards, and with 52 inches of annual rainfall plus persistent moisture in the air, water intrusion becomes a chronic problem. If you're dealing with mold, it's usually hiding in crawlspaces, around foundation cracks, or in attics where roof leaks have gone unnoticed for years.

Most mold remediation projects in Chattanooga run between $1,200 and $3,750. Where you land in that range depends on how much area needs treatment, whether the mold has spread into walls or insulation (which costs more to access and remove), and how much moisture control work your contractor recommends. A small bathroom mold spot might be $1,200. A crawlspace remediation with new vapor barriers and ventilation adjustments could hit $3,750 or beyond.

Tennessee requires contractors handling mold remediation projects over $25,000 to hold an S-Mold Contractor License. You can verify any contractor's license at search.cloud.commerce.tn.gov. Most smaller jobs won't trigger this requirement, but it's worth checking anyway, especially if a contractor quotes you more than $25,000.

Here's what matters most for Chattanooga specifically: get a moisture assessment along with your mold quote. Many contractors will identify mold but skip the underlying water problem, and you'll have mold again within a year. Ask whether they're addressing crawlspace ventilation, grading issues, or gutter problems, not just removing what's visible.
