Black Mold Removal in Castalian Springs, TN

What happens when you call

The call connects you with an independent local mold remediation company that serves eastern Sumner County. Be ready to describe where the dark growth is, roughly how large it looks, whether the wall or floor feels soft, and whether there was a leak, a storm or water under the house. Most companies will set up a visit to take moisture readings and photos. Ask for a written scope that names the water source, the containment plan, every material to be removed and how the area will be checked afterward.

What affects the cost

Angi reports a national typical range of $1,223 to $3,758 for mold remediation, and most pros charge $10 to $25 per square foot. Middle Tennessee prices vary. On a dark-mold job the main drivers are:

• How many square feet are affected, and whether it spreads inside the wall cavity.
• Material: wiping sealed wood is far less work than cutting out drywall, carpet pad or insulation.
• Access in a crawl space, attic or tight closet.
• Containment, air filtration and disposal.
• Rebuilding afterward, which is often a separate bill.

For jobs of $25,000 or more, Tennessee requires a contractor's license, and mold remediation is the S-F classification. Sumner County is not on TDCI's Home Improvement license list.

Local conditions

Castalian Springs is a historic rural community on State Route 25, about 7 miles east of Gallatin and 30 miles from Nashville, home to Wynnewood and Bledsoe's Fort. The area has no city codes office; building permits for rebuilding walls or framing come from the Sumner County Building & Codes Department in Gallatin. Sumner County's Flood Insurance Study says headwater streams rise fast in heavy local rain, with major floods most often in late winter and early spring. Add humid summers, crawl spaces and older farmhouses with patched roofs, and dark growth tends to show up on north walls, under sinks and on floor framing.

Before the company arrives

• Shut off the water feeding a leak, if you can find it.
• Take photos of the growth and any water marks for your records and your insurer.
• Don't scrub, sand or spray large patches; that can spread spores.
• Turn off the HVAC if the growth is near vents or the ducts are suspect.
• Clear a path to the area and the crawl space access.
• Keep anyone with asthma away from the room.
