Crawl space encapsulation in Roswell, Georgia
A musty smell upstairs, damp air under the floor, insulation hanging off the joists. Crawl space encapsulation seals the ground and walls under the house and then dries the air. Call this number to talk with an independent local waterproofing company that does the work in Roswell.

The cause
Why a vented crawl space turns damp in a Georgia summer
Foundation vents were meant to air a crawl space out. In hot, sticky weather they do the reverse. Outdoor air holds more water than the cooler space under your floor can carry, so it drops that water on the first cool surface it touches.
- Outdoor air comes in through the foundation vents for months on end.
- Ducts and pipes run colder than that air, so they sweat and drip onto the ground.
- Fiberglass batts take up the damp, grow heavy and peel away from the subfloor.
- Bare soil gives off moisture of its own, which rises into the framing.
Encapsulation shuts each of those paths. A sealed liner covers the soil and the walls, the vents are closed, and a dehumidifier keeps the air dry. The crawl space encapsulation page shows the parts and lists what to ask before you agree to anything.
If water stands under the house after rain, that has to be dealt with first. A liner laid over a puddle hides the problem. See crawl space repair for drains and pumps.
Start from the symptom
What are you seeing?
A musty smell on the main floor
Air from the crawl space rises into the rooms above. Damp wood and wet insulation are the usual source.
Standing water under the house
Rain is reaching the crawl space from the yard, a downspout or the soil itself.
Water along the basement wall after rain
Groundwater is pushing in where the wall meets the floor.
Something else
Soft floors, white powder on block, a pump that keeps cycling: the full list sorts each one.
Services
Waterproofing work you can call about

- Basement waterproofingA channel cut along the slab edge gathers seepage where the wall meets the floor and feeds it to a pump.
- Exterior waterproofingThe wet wall is dug out, coated and drained at its base, then the trench is refilled so the surface sheds rain.
- Sump pump installationBasin, pump, check valve and a battery-fed second pump for the storm that knocks the power out.

Quick answers
Is crawl space encapsulation the same as a vapor barrier?
No. A vapor barrier is plastic laid over the soil. Encapsulation also covers the walls and piers, seals the seams, closes the vents and adds a way to dry the air. The encapsulation page compares the two.
Who actually comes to the house?
A waterproofing company that is independent of this website. Roswell Crawl Space makes the phone introduction and has no hand in the inspection, the price or the job.
Do I pay Roswell Crawl Space anything?
No. You are never billed for the call or the introduction. The companies pay a fee for it, which the referral disclosure explains.
Can I call about a basement instead of a crawl space?
Yes. A house built into a slope has its uphill basement wall below ground, and that wall takes the water. Seepage, leaks, sump pumps and outside drainage are all reasons to call.
