Mold remediation in Columbia is the contained removal of mold and the water-damaged materials supporting it, followed by cleaning and drying so the problem doesn't return. EPA points homeowners to a professional for growth over about 10 square feet or mold tied to flooding. Call the number on this page to be connected with a local mold remediation company in Columbia.
Columbia and the Duck River
Columbia, the Maury County seat, grew up along the Duck River, the longest river entirely inside Tennessee. In May 2010 the river at Columbia reached 44.91 feet, its seventh highest level on record. In February 2019 it crested at 42 feet, the highest since 1991; police and firefighters went door to door urging Riverside residents from 3rd Avenue south to Riverside Drive to leave, riverside parks went underwater and some nearby buildings took on water. The Tennessee Department of Health warns that mold can start growing within 48 hours of flooding.
What to do now
- Make sure the house is safe to enter and the power is off to any wet areas.
- Pull out soaked carpet, pad and insulation that can't be dried within 48 hours.
- Run dehumidifiers. TDH notes basements often sit above 50 percent relative humidity and need moisture reduction.
- Wear an N-95 mask and gloves for any handling; EPA says children shouldn't help with flood cleanup.
- Photograph damage before removal for insurance.
Signs and likely causes
| What you see | Likely cause |
|---|---|
| Tide line on drywall | Floodwater that wicked into walls |
| Musty basement with no visible growth | Humidity above 50 to 60 percent |
| Spots inside cabinets under sinks | Slow drain or supply leak |
| Dark growth on attic sheathing | Roof leak or poor attic ventilation |
Cost factors
Angi reports a national typical range of $1,223 to $3,758 for remediation, and basement jobs nationally at $500 to $3,000. Maury County pricing varies. Flood jobs cost more because more material comes out and more rooms need containment. Maury County is not among the counties where the state Home Improvement license covers smaller residential jobs, but any project of $25,000 or more needs a Tennessee contractor's license, and mold remediation is classification S-F.
Rebuilding after remediation goes through the City of Columbia's Development Services building inspections office on N Garden Street. The city takes part in the National Flood Insurance Program and manages floodplain rules under Article 6 of its zoning ordinance, so properties near the river may face extra requirements; ask Development Services before major repairs. Keeping receipts and photos from the cleanup helps with both insurance and any later permit questions.
