Water Damage Restoration in Chattanooga, Tennessee

The Tennessee River once put all of Chattanooga under water. The 1867 flood crested at 58 feet and inundated the city, and downtown still sits around 676 feet above sea level, among the lowest ground in East Tennessee. TVA dams have tamed the river since the 1930s, but the creeks that drain Missionary Ridge, Walden's Ridge and north Georgia still rise fast, and average yearly precipitation here tops 52 inches.

No crews work for The Restoration Job; it simply routes your call.

Pricing and timing are set by whichever company takes the job, and many of them handle after-hours emergencies.

A River Held Back by Dams, and Creeks That Are Not

Since the Tennessee Valley Authority system took shape in 1933, the highest Chattanooga river stage has been nearly 37 feet, reached in 1973. Without TVA regulation that same flood would have crested around 52.4 feet. In May 2003 the river came up again, cresting at 36.1 feet on May 8, and the National Weather Service estimated damage in Hamilton County alone at close to $20 million, with hundreds of people evacuated.

The bigger day-to-day threat is usually the tributaries. South Chickamauga Creek flows out of Catoosa County, Georgia, through East Ridge and into the city. After the 1973 flood, a 2.6-mile levee was built along its west bank between Shallowford Road and I-75 to protect the Brainerd neighborhood. Properties outside that levee, and along smaller streams that drain the ridges, can still take water when storms stall over the valley.

Easter 2020 and the Storm Track Through East Brainerd

Late on April 12, 2020, an EF3 tornado crossed from Fort Oglethorpe, Georgia, into eastern Chattanooga, cutting through Harris Hills, East Brainerd, Drake Forest and Holly Hills before moving on to Collegedale and Ooltewah. Across the metro area, 2,718 properties were damaged and 254 destroyed. Torn roofs and broken windows let rain into homes that never saw floodwater, which is why storm damage cleanup after wind events often turns into a drying job as well.

Summer is busy too. July brings a secondary peak in rainfall from thunderstorms, and a slow-moving cell can overwhelm gutters, window wells and basement drains in an hour. The remnants of Ida dropped more than 4 inches at several Chattanooga gauges between August 31 and September 1, 2021.

Basements, Crawl Spaces and Hillside Lots

Chattanooga's housing ranges from older homes in long-established neighborhoods such as Fort Wood, Ferger Place, Highland Park and St. Elmo to ridge-top houses on Missionary Ridge and newer subdivisions out toward Hixson and Tyner. That mix creates different trouble spots:

• Hillside foundations. Houses cut into a slope often have one basement wall below grade on the uphill side, where runoff collects and seeps in.
• Older crawl spaces. Original plumbing and minimal ventilation let small leaks soak floor framing unnoticed.
• Valley-floor lots. Homes near creeks or on low streets may see surface water or sewer backup when lines surcharge in heavy rain.
• Historic districts. Battery Place, Glenwood, Missionary Ridge and others are locally designated, so exterior repairs may need approval.

What Happens After Water Gets Inside

Shut off the water main for plumbing failures, and keep power off to any flooded room until it is safe. Photograph everything before moving it. Creek and street water should be treated as contaminated, so items like carpet pad and saturated drywall generally come out rather than being dried in place.

A restoration crew will usually extract standing water, remove materials that cannot be saved, then set air movers and dehumidifiers and check moisture readings each day until framing and subfloor are back to normal. Professional flood cleanup in Chattanooga also includes cleaning and disinfecting surfaces that stay in place. Rebuilding should wait until readings confirm the structure is dry.

Humid Summers and Mold in the Tennessee Valley

Warm, humid air settles in the valley from late spring into fall, and that makes wet materials a mold risk within a couple of days. Basements and crawl spaces stay damp longest, especially on the shaded side of a ridge. Running a dehumidifier, keeping gutters clear and directing downspouts away from the foundation all help. If growth has spread across drywall or framing, mold cleanup with containment keeps spores from moving to clean rooms while the work is done.
