Spray Foam Insulation in Calhoun, GA

Calhoun's a fast-moving Gordon County town right on I-75, and we run the corridor down there regularly. There's steady residential growth on the edges and big carpet and distribution buildings everywhere you look — and both leak. New subdivisions go up with builder-minimum fiberglass; the big commercial buildings burn money conditioning wide-open metal-roofed space. Either way it traces back to an envelope that isn't sealed, and that's what we do.

Why Calhoun homes need spray foam

New subdivisions go up fast with fiberglass that leaves the attic and walls leaking air from day one — new doesn't mean sealed. Older homes leak from age. Fiberglass can't stop air swapping in and out either way, so the HVAC fights the attic and the bill climbs. Open-cell spray foam expands into the gaps and seals the whole shell. We'll seal and encapsulate the crawl space too, so ground moisture and humid air stop coming up into the house. Whether your place is brand new or been here a while, a tight envelope is what finally lets your system keep up and brings the bill down. Outside Calhoun? We spray foam attics and crawl spaces all across our service area. We're regularly in nearby Dalton, Chatsworth, and Rocky Face too.

Calhoun sits at about 659 feet on the Oostanaula River, right where Oothkalooga Creek comes in. Just northeast of town, at New Echota, the Coosawattee and the Conasauga join to form the Oostanaula. That's three river systems converging within a few miles of where you live, in a county that averages better than 54 inches of rain a year. Gordon County is Valley and Ridge country - limestone and dolomite under red clay, with springs and low-gradient streams throughout. Ground moisture is not an occasional problem here. It's the baseline condition.

We've run spray foam out of Chattanooga for 17+ years, and Calhoun is regular work. Straight shot down I-75, which runs along the eastern edge of town with five interchanges. We bring our own crews and our own rigs. Nothing gets subbed out. Whether it's a new house going up on the south side, a 1960s ranch near downtown, or a flooring plant off the interstate, the job is the same: find the leaks, seal the shell, and get the moisture out of the equation.

New Homes, plants, warehouses — we handle it all

With I-75 running through Calhoun, commercial and industrial is a huge piece of the picture — and open-cell foam is right at home on a warehouse or plant roof, stopping condensation and cutting the cost of conditioning massive square footage. On the residential side we foam new construction before drywall and retrofit existing attics and crawl spaces. New build or big box, the principle's identical: stop the air from moving through the building.

Older homes near downtown

Calhoun was incorporated in 1852 and rebuilt more than once - a tornado leveled much of the city in March 1888 and a fire followed that October. What stands today around the Calhoun Downtown Historic District, listed on the National Register in 2011, is largely turn-of-the-century and early-1900s construction. These houses were built with tall ceilings, board sheathing, and no air barrier of any kind.

The failure mode is straightforward: the attic floor got a layer of batts at some point, and everything else was left alone. Heat leaves through the roof in winter, and in summer the attic runs well above outdoor temperature and pushes down into the living space. Foam applied to the roof deck brings the attic inside the conditioned envelope and stops the air movement instead of just slowing the heat down.

Post-war and mill-era ranches

Gordon County's economy ran on cotton mills that turned into carpet and textile work, and the housing built for that workforce is still a big share of the market. Ranches and split-levels with vented crawl spaces, ducts in the attic, and fiberglass that's been sitting for decades. Batts sag. They pull away from the framing. Rodents get into them. None of that matters as much as the fact that they never stopped air to begin with.

On these houses we usually do the roof deck and the crawl space together, because that's where the stack effect starts and ends.

New subdivisions

Calhoun is growing, and new construction here is generally built to builder-minimum spec, which means batts in the walls and attic and very little attention to air sealing. The gaps are always the same: top plates, band joists, recessed lights, HVAC chases, plumbing penetrations. A brand-new house can leak as much as a sixty-year-old one. If you're building, foam at the framing stage costs you nothing in demolition and seals the shell before the drywall ever goes up. See new construction.

Crawl spaces: no dehumidifier, because the seal is complete

Three rivers meet in this valley, and the air here carries it. Over 54 inches of rain a year, a long humid summer, and clay-and-limestone ground that holds water. If your house has a vented crawl space, you've got an open invitation for that humid outside air to come under your floor, hit cooler surfaces, and condense. That's how you get musty smells, cupping hardwood, sticky doors, and an HVAC system fighting a load it shouldn't have.

This is where we're different. Most crawl space systems in this area depend on a dehumidifier running in the corner - a machine, a power draw, a filter, a unit that eventually gets replaced. That's because the space was never fully sealed. We seal the crawl completely, so the humid river-valley air doesn't get in. No dehumidifier to run, none to maintain.

Common questions from Calhoun homeowners

You're a Chattanooga company. Do you actually work in Gordon County?
Yes, regularly. Calhoun is a straight run down I-75 and it's inside our normal service radius - we cover roughly 100 miles out of Chattanooga, which puts all of north Georgia in range. Our own crews do the work. You're not getting a local sub with our name on the invoice. We're often in Dalton and Chatsworth the same week.

Our place is down near the river bottom and it always smells damp. Will foam help?
It's the most common call we get in Calhoun. The smell is almost always coming up from a vented crawl space, not from inside the house. We seal the crawl and there's no dehumidifier needed, because the outside air never gets in. Once the moisture source is cut off, the smell goes with it.

We're building a new house off Highway 41. When should you come in?
After the roof is dried in and the rough-ins are done, before insulation inspection and drywall. That's the window where we can spray the roof deck and the walls with everything still open. Call us during framing so we can get you on the schedule for the right week rather than the week you happen to call.

Can you do a flooring plant or a distribution warehouse?
Yes. Metal buildings and commercial work are a real part of what we do, not a sideline. On a metal roof deck, closed-cell foam sprayed to the underside removes the gap where warm inside air reaches cold steel, which is what causes the dripping people mistake for a roof leak.

Is the old fiberglass in our attic worth keeping?
Sometimes, sometimes not. If it's wet, matted down or rodent-fouled, it comes out - we do insulation removal and haul-off. If it's dry and out of the way, we may be able to leave it and work the roof deck above it. We'll tell you which it is when we look.
