Smyrna has a mix of older homes and large newer subdivisions, and attics in both can grow mold when a roof leaks, an exhaust fan dumps steam into the attic, or warm house air condenses on cold decking in winter. Removal means cleaning or replacing the affected wood and insulation and fixing the source. Call the number on this page to be connected with a local mold remediation company in Smyrna.
Attic moisture in Smyrna homes
In ZIP 37167, about 19 percent of houses were built in 1979 or earlier. Attics in houses of that age often have less insulation and fewer vents than current construction, and their roofs may be on a second or third layer of shingles. Newer homes carry their own risks, such as fans that exhaust into the attic. Roughly 38 percent of occupied homes in the ZIP are rented. Middle Tennessee's humid summers and cold snaps put every attic through big swings in temperature and moisture each year.
What to do now
- Look from the hatch. Use a flashlight to check the roof deck, rafters and insulation without walking across the joists. Skip this if you have asthma or a weakened immune system.
- Trace the fans. Follow bathroom and kitchen exhaust ducts and note any that stop short of an outside vent.
- Check the eaves. See whether insulation is packed against the soffits, blocking the intake vents.
- Hold off on attic HVAC equipment. EPA advises against running a system you suspect is contaminated, since it can spread mold through the house.
- Photograph everything. Pictures help a company scope the job and help with any insurance claim.
- Renters, write to the landlord. If a roof leak or venting problem isn't fixed, the Property Maintenance division of Smyrna Building Safety takes reports through the My Smyrna App.
What you see and what usually causes it
| What you see | Likely cause |
|---|---|
| Dark film across the north slope of the decking | Winter condensation from house air leaking upward |
| A ring-shaped stain around a vent pipe or chimney | Failed flashing or a cracked pipe boot |
| Wet patch on the deck right above a bathroom | Exhaust fan blowing into the attic |
| Rusty nail tips | Repeated condensation on cold metal |
| Musty smell upstairs in summer | Sweating ducts or damp insulation in attic heat |
Cost factors
Angi puts attic mold remediation at about $1,000 to $4,000 nationally, and Middle Tennessee prices vary. The square footage of affected wood, attic height, insulation removal, and any roof or duct work set the total. Smyrna is in Rutherford County, so residential jobs from $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; mold remediation falls under the S-F classification. Check any company on TDCI's Verify a License search. Replacing decking or rafters may need a permit from Town of Smyrna Building Safety.
