Spray Foam Insulation in Tunnel Hill, GA

Tunnel Hill sits just north of Dalton along the I-75 corridor, and many homes in the area were built when insulation standards were minimal. Foametix installs open-cell and closed-cell spray foam in attics, crawl spaces, walls, and metal buildings throughout Tunnel Hill and Whitfield County. Our crew drives up from Chattanooga — same trucks, same team, same standards every time. Veteran-owned with over 17 years of experience.

Why Tunnel Hill homes need spray foam

A lot of Tunnel Hill's housing went up in the 70s and 80s when a few inches of fiberglass in the attic and a vented crawl space were considered fine. They weren't — and they definitely aren't now. That fiberglass has settled to almost nothing, the crawl spaces are damp and open, and the houses leak air through every penetration in the ceiling and floor. Spray foam seals all of it. The attic gets sealed from above, the crawl space gets encapsulated from below, and the house stops hemorrhaging energy. Outside Tunnel Hill? We spray foam attics and crawl spaces all across our service area. We're regularly in nearby Rocky Face, Dalton, and Ringgold too.

Tunnel Hill sits at about 840 feet along the western base of Chetoogeta Mountain, in northwest Whitfield County and the southern edge of Catoosa County. That's higher ground than Dalton or Rocky Face, and it's exposed. The town is named for the Western & Atlantic Railroad tunnel bored through Chetoogeta in the late 1840s - 1,497 feet long, dedicated October 31, 1849, and finished in 1850. It's the oldest railroad tunnel in the Southeast.

So this is old ground with a small population and a housing stock spread across a wide range of decades. We've sprayed foam out of Chattanooga for 17+ years and Tunnel Hill is a short run for us. Our own crews, our own rigs, no subcontractors. Whether you're in a house near the old tunnel, a build off the corridor, or a shop on a few acres, the approach is the same: seal the shell and stop the air.

Residential, commercial, and metal buildings along I-75

Tunnel Hill sits along the Highway 41 and I-75 corridor with homes, churches, small commercial buildings, and light-industrial metal structures. We insulate all of them — attics and crawl spaces for homes, closed-cell foam for metal buildings. Come look for free, tell you what it costs, and get it done.

Old town houses and farmhouses

This community goes back to 1848, and some of what's here reflects that. Frame houses, board sheathing, additions layered on over generations, crawl spaces or pier foundations vented all the way around. Nobody built these to hold conditioned air, because conditioned air wasn't a thing yet.

What you feel is the stack effect. Heat climbs out through the attic, and the house pulls replacement air in low - through the floor, the foundation, and every gap around the band joist. Piling more batts on the attic floor doesn't slow that down, because the air goes around them. Foam on the roof deck brings the attic inside the envelope and closes the top of the stack.

Subdivision homes from the growth years

A good share of the newer housing here went in through the 1990s and into the 2000s. That vintage is usually framed and insulated to whatever the code minimum was at the time: batts in the walls, batts in the attic, and essentially no air sealing. The leak points are predictable and always the same - top plates, recessed can lights, bath fan housings, HVAC chases, plumbing penetrations, and the band joist.

You can spend years chasing those individually with caulk and foam board. Or you can seal the plane once at the roof deck and the floor and be done chasing.

Shops, barns and metal buildings

Plenty of properties out here have acreage and a building on it - a shop, a pole barn, a metal building used for storage, work, or a business. Bare metal roof panels in this climate sweat. Warm inside air reaches cold steel and condensation forms, then drips on whatever is underneath. Closed-cell foam sprayed to the underside of the deck bonds directly to the panel, so there's no gap where that can happen, and it stiffens the structure while it's at it. See metal buildings.

Weather at 840 feet

Tunnel Hill catches weather that houses down in the valley don't. Wind loads the shell. Cold air drains off the mountain at night. In an unsealed house, that pressure difference runs all winter, and every gap in the envelope becomes a place the weather is working on around the clock.

Crawl spaces: no dehumidifier, because the seal is complete

Hillside lots put crawl spaces at uneven depths and push water toward the foundation, and this is red clay over limestone valley ground - it holds water rather than shedding it. Most crawl space systems around here finish with a dehumidifier running in the corner, drawing power and needing filters, because the space was never fully sealed. We seal it completely. No dehumidifier to run, none to maintain. If the humid air can't get in, there's nothing to pull back out. More here: crawl space encapsulation in Tunnel Hill, GA.

Common questions from Tunnel Hill homeowners

You're based in Chattanooga. Do you really come out to a town this size?
Yes. Tunnel Hill is a short run down I-75 from us and it's well inside our normal service area. We're in Whitfield County regularly - Dalton and Rocky Face are on the same route - and we run our own crews, so you're not waiting on a subcontractor's schedule.

Our house is one of the older ones near the tunnel. Is it too far gone to be worth foaming?
Almost never. Older houses usually show the biggest change, because they're starting from no air barrier at all. We generally work the attic and the crawl space on a house like that, which means we're not opening finished walls.

We're on a hill and the crawl space is deeper on one side. Does that complicate it?
Not really. Uneven crawl spaces are normal on sloped lots out here and we work in them routinely. We seal the walls and the rim regardless of the depth, and there's no dehumidifier in our system because the seal is complete.

Can you insulate a pole barn or a shop building?
Yes - metal buildings and shops are regular work for us. If you're not conditioning it but you're tired of condensation dripping on your equipment, foam on the roof deck handles that too.

Do you spray during new construction, or only on existing houses?
Both. On new construction the best window is after the roof is dried in and the rough-ins are complete, before insulation inspection and drywall. Get us on the schedule during framing.
