Basement mold in Columbia most often follows Duck River high water, heavy-rain seepage, plumbing leaks, or humid air on cool walls. Removal clears out moldy porous materials, cleans and dries the structure, and has to be paired with keeping the water out.

Columbia and the Duck River
Columbia, the Maury County seat about 41 miles from Nashville, grew up along the Duck River, the longest river entirely within Tennessee. In May 2010 the Duck reached 44.91 feet at Columbia, its seventh-highest level on record. In February 2019 it crested at 42 feet, the highest since 1991; fire and police went door to door urging Riverside residents from 3rd Avenue south to Riverside Drive to leave, riverside parks went under, and some buildings near the river took water inside. About 37 percent of Columbia's occupied homes are rented.
Columbia takes part in the National Flood Insurance Program, and its floodplain management page links the city's FEMA flood map panels. Development Services answers floodplain questions.
What to do right away
- Make sure the power to wet areas is safe before you go down.
- Pull out wet carpet, cardboard and fabrics. The Tennessee Department of Health says mold can begin within 48 hours of flooding.
- Dry the space with fans and a dehumidifier. TDH notes that basements often sit above 50 percent relative humidity and need moisture reduction.
- Photograph damage before discarding anything.
- Avoid running a furnace or air handler that took water or shows mold.
- Check your address on the city's flood map panels before rebuilding.

Signs and their usual causes
| What you see | Likely cause |
|---|---|
| Silt and a water line on walls | River or surface floodwater inside |
| Damp lower block after a wet week | Saturated soil pushing water through the foundation |
| Dark spotting behind paneling | Moisture trapped behind finishes |
| Musty smell with no visible growth | Hidden mold in walls, under flooring or in ducts |
Cost factors
Angi reports national ranges of about $500 to $3,000 for basement mold remediation and $2,250 to $7,100 for foundation sealing; costs in Middle Tennessee vary. Flood jobs tend to cost more because more material comes out and drying takes longer. Maury County is not on the state Home Improvement license list, but jobs of $25,000 or more require a Tennessee contractor's license, with mold remediation under the S-F classification. Rebuilding permits come from Columbia Development Services' Building Inspections office on North Garden Street, and renters can report unrepaired leaks to its Codes Enforcement staff. The Maury County Health Department on Hampshire Pike handles local health questions.
