A complete moisture-control system for your home's crawlspace. A heavy-duty vapor barrier seals the floor and walls, vents are closed, and a dehumidifier keeps conditions stable year-round, stopping mold, rot, pests, and energy loss at the source. We encapsulate crawlspaces throughout Coweta and Fayette County, based right here in Newnan.
Coweta and Fayette County homes deal with hot, humid summers and ground moisture year-round. An open or vented crawlspace pulls that humid air directly up through your floors into your living space, bringing mold spores, allergens, and energy loss with it. The EPA estimates that up to 40% of the air you breathe on your first floor comes from your crawlspace. Encapsulation stops that at the source.
These two complaints almost always trace back to the same cause: an unsealed crawlspace. Humid ground air rises into your home through the stack effect, the same natural airflow that pulls air up through a chimney, carrying that musty smell with it. That's usually the first sign something's wrong underneath the house, well before you'd notice visible mold or standing water.
Cold floors have a more direct explanation: with no insulation or vapor barrier below, your floor is essentially sitting on top of outside air. Conditioned air from inside the house is also escaping straight down through the same gap, which is why cold floors and high energy bills tend to show up together.
A reinforced vapor barrier covers every inch of soil and foundation walls, blocking ground moisture from entering your home.
Keeping relative humidity below 60% eliminates the conditions that allow mold and structural wood rot to develop.
Sealed crawlspaces reduce heating and cooling costs by 10–20% by eliminating conditioned air loss through the floor.
Prevents mold spores, allergens, radon, and soil gases from rising into your living space through the stack effect.
A properly sealed crawlspace eliminates the dark, damp environment that termites, rodents, and other pests seek out.
A clean, dry, encapsulated crawlspace is a selling point inspectors and buyers notice.
We start with a thorough inspection, checking for existing moisture damage, mold, pest activity, and drainage issues. Any problems get addressed before the liner goes down, because encapsulating over an existing problem traps it.
Next, we lay a 12–20 mil reinforced polyethylene liner across every inch of the crawlspace floor, running it up and attaching it to the foundation walls. Seams are overlapped and taped with vapor-bond tape so there are no gaps. Foundation vents are sealed to prevent outside air from re-entering the conditioned space.
Finally, we install a crawlspace dehumidifier sized for your specific space, keeping humidity at a controlled level year-round. Most installations are completed in one to two days.
Full encapsulation, liner, sealed vents, and dehumidifier, typically runs $3.50–$7.50 per sq ft installed, depending on crawlspace size, accessibility, and how much prep work (moisture damage, old debris, drainage issues) needs to be addressed first. We give you an exact number after a free inspection, itemized so you can see what you're paying for.
