Spray Foam Insulation in Rossville, GA

A mill town on the line

Rossville grew up around the Peerless Woolen Mills and the railroad, and its housing shows it. Census Bureau estimates put the median year built at about 1959, with nearly eight in ten homes predating 1980 and very little built since 2000. Mill houses and cottages from the early twentieth century sit on the grid streets near the old mill site; 1940s and 1950s frame and brick houses fill the neighborhoods toward the ridges on either side. The John Ross House, one of the oldest structures in the region, is a reminder of how long people have lived in this spot.

The town is in Walker County, Georgia, a few hundred feet from Chattanooga. That means Georgia's building codes, permits from the City of Rossville or Walker County, and electric service from Georgia-side utilities rather than EPB. TVA EnergyRight rebates flow through TVA's local power companies, so whether they apply to a Rossville address depends on the utility.

What old mill houses need

A Rossville mill house is typically a small frame structure on brick or block piers or a shallow crawl space, with wood floors directly over the ground, no wall insulation and a low attic. The crawl space is open or vented and the floor system has been exposed to humid air for a century. Fiberglass added at some point along the way is wet and falling. The floors are cold in winter and the house is damp in summer.

Closed-cell foam is the material for these houses because it tolerates the moisture and adds rigidity to old framing. Sprayed to the underside of the floor system or to the crawl space walls and rim joist, depending on the foundation, it seals and insulates the bottom of the house. Because the crawl spaces are often shallow, access is the main planning item and we look at it carefully on the assessment. The attic gets sealed and brought to depth, and walls get foam when siding or plaster comes off for repair.

Low ground and creek bottoms

Rossville sits in the valley between Missionary Ridge and the ridges to the south and west, with Chattanooga Creek and its branches draining the low ground toward the Tennessee River. Homes in the bottoms along the creek sit on damp ground all year, and a vented crawl space there is a wet one. For those houses, fixing drainage where needed and then sealing and drying the crawl space changes how the whole home lives.

For Rossville homeowners weighing the cost, the crawl space is the place to start. It is where the moisture is, it is where the failed insulation is, and it is the part of the house that a sealed vapor barrier and closed-cell foam fix for good.
