In Thompson's Station, a professional mold test makes sense when there's a defined question, such as whether a musty room hides growth or whether remediation was completed properly. If you can see the mold, EPA says sampling is usually unnecessary. Call the number on this page to be connected with a local mold inspector in Thompson's Station.

Local conditions in Thompson's Station
Thompson's Station is a town about 26 miles south of Nashville, between Franklin and Spring Hill, with railroad-era roots and Civil War history; it was incorporated in 1990. In the May 2010 flood, about 14.4 inches of rain fell here over two days. Williamson County emergency management lists the Harpeth River and its creeks as the main local flood sources and warns that flash floods can come with little warning. Most of the moisture trouble that leads to testing, though, is ordinary: humid summers, crawl spaces, attic ductwork, and small plumbing leaks that stay hidden in finished walls.
Kit, professional test or no test?
| Store kit | Professional sampling | No test | |
|---|---|---|---|
| How it works | Open dish or swab mailed to a lab | Air, surface or wall-cavity samples with an outdoor control | Visual check and moisture readings |
| What it tells you | Little; spores land in a dish in nearly any home | How indoor results compare with outdoors, and what is growing on a stain | Where the water is and how much material is affected |
| When it fits | Rarely | Hidden growth questions, clearance after cleanup, documentation | Visible mold with a clear cause |

Signs to bring up on the call
- A smell that returns every time the AC cycles on.
- Bubbling paint or soft drywall near a bathroom or laundry.
- A crawl space vapor barrier with water pooled on top.
- Recurring spots on a bedroom ceiling below the attic.
Timing and permits
Book air testing when the house has been closed up and lived in normally for a day, and schedule any clearance sampling after cleanup but before walls are closed. Angi's national range for a mold test is about $250 to $500, more with additional samples; local prices vary. Building permit applications for repairs are submitted to the Town of Thompson's Station, where Planning and Codes handle plan review together, so call the town to confirm what a given project needs. For health questions, the Williamson County Health Department in Franklin and the Tennessee Department of Health's Healthy Homes program are good places to start. EPA notes mold can irritate the eyes, skin, nose, throat and lungs.
