Most attic mold in Columbia starts with moisture that collects on the roof deck: household humidity condensing in winter, a storm leak, or a fan that empties into the attic. Removing the growth and correcting that moisture go together. Call the number on this page to be connected with a local mold remediation company in Columbia.

Columbia and the Duck River valley
Columbia, the Maury County seat about 41 miles south of Nashville, grew up along the Duck River, the longest river entirely within Tennessee. The river has a long flood record here. In May 2010 it reached 44.91 feet at Columbia, its 7th highest level on record, and in February 2019 it crested at 42 feet, the highest since 1991, as police and firefighters urged Riverside residents from 3rd Avenue south to Riverside Drive to evacuate. Flooding is a lower-floor problem, but a house that took water and dried slowly carries extra humidity upward for months, and the Tennessee Department of Health notes that the state's humidity on its own can lead to mold growth. About 37 percent of occupied homes in Columbia are rented, so many residents will need a landlord to deal with an attic problem.
First steps
- Shine a light across the underside of the roof deck and note how far the staining runs.
- Look for water trails on rafters that lead back to a vent, chimney or valley.
- Check that the bathroom fan duct is attached and runs outside.
- Keep people with asthma or weakened immune systems out of the attic, as EPA advises.
- Renters: send the landlord written notice, with photos.
- After a flood, include the attic in your checks once the lower floors are dry.

What the signs usually mean
| You notice | Often caused by |
|---|---|
| Dark film across a whole slope | Indoor moisture condensing on cold decking |
| Staining that started after a storm | Shingle, flashing or vent leak |
| Wet spots along duct runs | Ducts sweating in summer heat |
| Damp insulation near the eaves | Wind-driven rain at the roof edge, or blocked soffits |
Cost and city offices
Angi lists a national typical range of about $1,000 to $4,000 for attic mold remediation; prices in Maury County vary. Affected area, access, insulation and any roofing work drive the number. Permits for replacing decking or rafters come from the City of Columbia Development Services building inspections office on N. Garden Street, and renters with a leak a landlord won't fix can contact Columbia Codes Enforcement. Maury County isn't on the state's Home Improvement license list, but projects of $25,000 or more need a Tennessee contractor's license, with S-F as the mold remediation classification. The Maury County Health Department can help with health questions.
