Post-Remediation Clearance Testing in Cedar Hill, TN

A small town with damp ground nearby

Cedar Hill is a town of about 300 people on U.S. Route 41 in northwestern Robertson County, roughly 30 miles from Nashville, whose economy long served surrounding tobacco farms. Swampy ground sits beside the Cedar Hill Swamp Wildlife Management Area across the CSX tracks. The Tennessee Department of Health notes that the state's humidity alone can lead to mold growth, and older farmhouses, outbuildings converted to living space and homes over crawl spaces all give moisture places to linger.

Steps at the end of remediation

1. Ask what caused the mold and confirm that repair is done, whether it was a roof, a plumbing line or ground moisture under the floor.
2. Have the crew leave containment and air filtration in place.
3. Call an independent inspector, since Angi advises keeping testing and removal with different companies.
4. Expect a walk-through, moisture readings and, if useful, surface or air samples.
5. Get the result in writing before any wall, floor or insulation work begins.

What the inspector looks for

EPA recommends keeping indoor humidity below 60 percent and ideally between 30 and 50 percent. A cleaned crawl space that stays muggy all summer is likely to need the work again. Ask the inspector to note humidity readings in the report, along with whether any vapor barrier, sump or dehumidifier listed in the plan was actually installed and running.

Cost factors

National ranges from Angi run about $303 to $1,075 for an inspection and $250 to $500 for a mold test. Rural trip distance, sample count, lab speed and any return visit shape a Cedar Hill quote, and Middle Tennessee prices vary. Robertson County is one of the counties where residential jobs from $3,000 to under $25,000 need the state Home Improvement license. Before rebuilding, check with the Town of Cedar Hill about which office handles building permits for your address.
