Spray Foam Insulation in Chickamauga, GA

Chickamauga's a historic little town in Walker County, and we're down there regularly. A lot of these homes have stood for generations — beautiful, but airtight they are not. The owners all tell us the same thing: drafty in winter, muggy in summer, and the HVAC runs constantly without ever getting it right. That's an old house leaking air through the attic and pulling damp up from the crawl space — and we can seal it without touching the character.

Why Chickamauga homes need spray foam

Homes from that era leak heat through the attic and pull humid air up from open crawl spaces, so they're drafty and muggy at the same time no matter how hard the system works. Fiberglass can't seal any of that. Open-cell spray foam goes in the attic and crawl space — out of sight — and seals the shell from the inside, so you keep the look of the home and lose the drafts. We'll seal and encapsulate the crawl space too, which is usually what kills the musty, humid feeling for good. You get even, comfortable rooms and a lower bill, and nobody walking up to the house can tell a thing changed. Outside Chickamauga? We spray foam attics and crawl spaces all across our service area. We're regularly in nearby Fort Oglethorpe, Rossville, and Lookout Mountain too.

Chickamauga grew up around a spring, and the spring tells you most of what you need to know about the ground under your house. Crawfish Spring still pushes about 14 million gallons a day out of the base of a small dolomite hill on Cove Road, right where the Chickamauga Limestone meets the Knox Dolomite. The town carried the spring's name until 1888. Chickamauga Creek runs past town too - Lee and Gordon's Mill sits about two miles east of downtown on the creek's west bank.

Ground like that stays wet. Add roughly 57 inches of rain a year, heaviest in winter and spring, plus hot humid summers, and your house gets worked from two sides at once. A house that leaks air moves all of it through the crawl space, up through the floors, and out the attic. That is the part we fix. We've been spraying foam for 17+ years out of Chattanooga.

Homes, buildings, shops — we handle it all

Around Chickamauga we seal older homes, the downtown and church buildings a small historic town is full of, and the barns, shops, and metal buildings out toward the country. Open-cell foam adapts to all of it — air-sealing an old attic without a gut job, drying a crawl space, or turning a bare metal building into usable space. We start by showing you exactly where it's losing money, then we seal it.

The old homes around Cove Road and the historic district

The Chickamauga Historic District covers about 130 acres around Cove Road, with 114 contributing buildings. Construction there starts in the 1840s - the Gordon-Lee house went up between 1840 and 1847. Houses from that stretch were built to breathe. Heavy framing, no sheathing wrap, open piers, dirt under the floor and vents cut in the skirt. Plaster walls with nothing behind them. The attic is a bare gable with a thin, settled layer over the ceiling joists, and the ceiling plane below it is full of holes you cannot see. You feel it as a cold floor in January and a musty smell in July, at the same time.

Mill village cottages on West 10th

The Crystal Springs Bleachery opened in 1909 and by the early 1920s ran 350 workers. The company houses are still standing on West 10th - hipped-roof cottages and shotgun plans, the standard Southern mill village types. They are small, they sit low on piers, and the crawl space under them is often only a couple of feet deep. Shallow crawls are the worst of both worlds: hard to work in, and close enough to the floor that ground moisture goes straight into the joists.

Postwar ranches and newer builds

Out from the district you get slab houses, brick ranches, and newer construction toward the military park. These have fiberglass batts hanging in the floor joists and ductwork run through a vented crawl space or a hot attic. Batts in a floor system sag, fall, and soak up humidity. Ducts in an unconditioned space lose air before it ever reaches a register. Sealing the envelope at the roof deck and the crawl walls brings the ducts inside the house instead of outside it.

Old houses, no exterior changes

Chickamauga is full of houses older than the 1863 battle and houses built in the decades right after it. Homes from that era were framed by people who assumed a fire in every room and air moving through the house all day. You cannot heat and cool one of them the way it was built and expect a modern power bill.

You also do not have to gut it. Foam goes on the underside of the roof deck and inside the rim joists. Nothing changes on the outside of the house. No siding comes off, no trim gets cut, no plaster gets opened up. The attic stops being an oven in August and stops dumping your heat in January.

Crawl spaces: no dehumidifier, because the seal is complete

Under the floor, our crawl space work needs no dehumidifier - the seal is complete, so there is no appliance in the crawl drawing power and no filter to swap. Closed-cell foam on the walls and rim, a heavy ground barrier, and the vents sealed shut. That is the whole system. See crawl space encapsulation in Chickamauga for how that job runs.

Common questions from Chickamauga homeowners

Do you cross into Georgia, or are you Tennessee only?
We cross. We're based in Chattanooga and work roughly a hundred miles out - southeast Tennessee and north Georgia both. We are in Walker County regularly, along with Fort Oglethorpe, Rossville and LaFayette.

My house is in the historic district. Will foam change how it looks?
No. Everything we do is inside - the roof deck in the attic, the rim joists, the crawl space walls. We do not touch siding, windows, trim or exterior masonry.

The crawl space under my mill house is only about two feet deep. Can you work in it?
Usually yes. Low crawls are common in the West 10th houses and we spray a lot of them. Our crew will get in there during the free evaluation and tell you straight whether there is working room.

Why does my house feel drafty and damp at the same time?
Because those are the same problem. Warm air escapes out the top of the house through the attic, and that pull draws humid air in at the bottom through the crawl space. Sealing the top and the bottom stops both ends of that loop.

We have a limestone spring and wet ground nearby. Does that affect the crawl space?
It does. Water moves easily through the limestone and dolomite here, so the soil under a lot of Chickamauga houses stays damp between rains, not just during them. Sealing the crawl takes the ground and the outside air out of the equation - with no dehumidifier in the plan, because the seal does the work.
