Smyrna sits beside Percy Priest Lake with the Stones River and Stewarts Creek nearby, and like much of Middle Tennessee it has plenty of homes over crawl spaces that trap summer humidity.

Crawl space moisture in Smyrna
Part of Percy Priest Lake lies inside town limits, and the Stones River and Stewarts Creek run nearby. Most crawl space mold here, though, comes from everyday humidity rather than open water: hot, wet summer air drifts through the foundation vents and condenses on cooler joists and ducts. In ZIP 37167, about 19 percent of houses were built in 1979 or earlier, and older crawl spaces often have thin or missing ground barriers. Roughly 38 percent of occupied homes in the ZIP are rented.
What to do now
- Look before you crawl. From the access door, check for standing water, fallen insulation and visible growth. Don't go in if you have asthma or a weakened immune system.
- Find obvious water. Check gutters, downspouts and the grade along the foundation, and listen for drips from supply or drain lines.
- Stop using suspect ducts. If ducts or the air handler sit in the crawl space and look moldy, EPA advises not running the system until it is checked.
- Take photos. They help the company scope the job and help with any insurance conversation.
- Renters: tell the landlord in writing. If a leak or moisture problem goes unfixed, the Property Maintenance division of Smyrna Building Safety takes reports through the My Smyrna App or by phone.
- Get a written scope. It should say where the water comes from, what gets removed, and how the space will stay dry.
What you see and what usually causes it
| What you see | Likely cause |
|---|---|
| Musty smell in the living area in summer | Humid air under the house condensing on wood and ducts |
| Wet or sagging fiberglass batts | Condensation, a plumbing leak, or water on the ground |
| Dark growth on joists near the vents | Outdoor air entering through foundation vents |
| Puddles on the barrier after storms | Gutters, downspouts or grading sending water toward the foundation |
| Sweating ducts | Cold supply ducts with damaged insulation sitting in humid air |
Cost factors
Angi's national ranges run about $500 to $2,000 for crawl space mold remediation and $1,500 to $15,000 for encapsulation; prices around Smyrna vary. The size of the space, clearance, insulation removal, drainage repairs and a dehumidifier all change the number. Smyrna is in Rutherford County, so residential jobs of $3,000 to under $25,000 need the state Home Improvement license, and jobs of $25,000 or more need a Tennessee contractor's license with the S-F mold remediation classification. Rebuilding damaged framing may need a permit from Town of Smyrna Building Safety.
