Crawl Space Encapsulation in Fort Oglethorpe, GA

Fort Oglethorpe sits just south of Chattanooga next to the Chickamauga Battlefield, straddling Catoosa and Walker counties. It's a mix of established mid-century neighborhoods and newer homes, and like the rest of North Georgia it gets long, humid summers. Those conditions turn a vented crawl space into a moisture trap, slowly working on the floors and air quality of homes all over town — until the space is properly sealed, no dehumidifier needed.

WHERE THE AIR ESCAPES

Why Fort Oglethorpe crawl spaces hold moisture

A vented crawl space pulls humid North Georgia air in through the foundation, where it condenses on the cooler ground and framing under your floor. That moisture feeds mold, rots joists, and soaks any insulation stapled below the floor until it sags. In established neighborhoods, those crawl spaces have been doing this for decades. And the stack effect carries the damp air up into your living space, so what's under the floor sets the air for the whole home. Adding more fiberglass under a wet floor doesn't fix it — the moisture has to be sealed out at the foundation.

BY THE FORT OR ON THE PARKWAY

Older homes and newer builds — both need sealing

Mid-century neighborhood home or newer build, our system seals the North Georgia humidity out for good. Closed-cell spray foam on the walls and rim joists seals and insulates the perimeter in one step; a heavy 15–20 mil reinforced ground barrier — the real material, not a 6-mil tarp — is sealed and overlapped to drain water back to the ground; and the vents are sealed where mechanicals allow so the crawl space joins your home's conditioned envelope. The result is a dry, conditioned crawl space, warmer floors, and cleaner air — with nothing running on your power bill. On decades-old framing, sealing is also the best way to stop further moisture damage.

By applying spray foam directly to the underside of the roof deck, it now insulates the attic space from the extreme heat that once radiated through the hot shingles, sheathing, and roof. The severe temperatures no longer exist in the attic. In short, the attic now becomes a passively "conditioned" space of the house that is just as comfortable as any other room in the home.

Benefits

A roof system insulated with Foametix spray foam reduces energy several ways. Energy loss from ducts located in the attic is essentially eliminated. The top of the building is much tighter resulting in less infiltration and exfiltration, so excess moisture isn't pulled into the attic. Infiltration through the ceiling is also reduced. In addition, the attic temperature is remarkably lower, which further reduces energy loads.

Energy Savings

  • Why don't you install a dehumidifier when other companies do?

    Because we actually seal the crawl space. We line the walls and rim joists with closed-cell spray foam — it's the insulation and the moisture-and-air barrier in one. Most companies don't run closed-cell foam, so they can't fully seal the space; they drop in a dehumidifier to manage the moisture they can't keep out. That's a bigger bill up front and an appliance running on your power for years. We're one of the only crews in North Georgia that truly seals it, so it stays dry on its own — no dehumidifier.

  • Is this more or less expensive than a dehumidifier system?

    Less, once you look past day one. Ours is a one-time seal with nothing to run — no dehumidifier on the power bill, no filters, no unit to replace in eight or ten years. Systems built around a dehumidifier usually cost more overall once you add the equipment, the electricity, and the upkeep.

  • My neighborhood is older — is sealing worth it?

    Often it's the best upgrade available — it protects decades-old framing and clears up the musty air these older crawl spaces push up into the house.

  • Will it lower my energy bills?

    Yes. A sealed, conditioned crawl space stops your heated and cooled air from leaking into the ground and eases the load on your HVAC — which shows up on the power bill.
