Crawl Space Encapsulation in Chatsworth, GA

Chatsworth sits at the foot of the Cohutta Mountains and Fort Mountain in Murray County — foothill country with heavy rainfall coming off the high ground and a lot of rural homes spread across it. That terrain sends water toward crawl spaces, and a vented design lets the resulting moisture sit against the framing. It's a setting that's especially hard on a crawl space — and one a dehumidifier can't keep up with. Sealing the space is the fix.

THE MOUNTAIN SWING

Why Chatsworth homes need crawl space encapsulation

The Cohuttas catch and shed a lot of rain, and that runoff feeds water toward the homes below. A vented crawl space pulls humid air in through the foundation while the runoff keeps the soil damp — condensing moisture onto the cooler ground and framing under your floor. Rural foothill homes often have larger, lower crawl spaces, so there's more area soaking it up. The stack effect then carries that damp, musty air up into the house. A thin 6-mil sheet on the dirt does nothing against foothill runoff and humidity.

HOMES AND WAREHOUSES 

Older homes, rural properties — both need sealing

In-town home or a rural place in the foothills, our system is tailored to the terrain and seals runoff and humidity out at the foundation. 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, sealed and overlapped, drains runoff and water back to the ground; and the vents are sealed where mechanicals allow so the crawl space joins your home's conditioned envelope. Where mountain runoff or the water table demands it, we add a sump pump. The result is a dry, conditioned crawl space, warmer floors, and cleaner air — with no dehumidifier running year-round. Larger foothill crawl spaces benefit even more from a proper seal.

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 Murray County 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.

  • There's a lot of runoff off the mountains — can you handle it?

    Yes. Heavy runoff is exactly why we seal with closed-cell foam and a heavy ground barrier and add a sump pump where it's needed. Larger foothill crawl spaces benefit even more from a real seal.

  • Will it warm up my cold floors?

    Yes. Sealing and insulating the floor with closed-cell foam keeps the cold ground from pulling heat out of your floors, so they feel warmer and rooms hold their temperature.
