We will tell you if crawl Space Vapor Barrier Installation is not what your Yemassee crawl space actually needs. Doing this stage out of order is the most common reason the work has to be repeated.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on lowcountry and coastal plain ground
A barrier earns its keep faster around Yemassee than almost anywhere. With the water table close to the surface the soil underneath is damp more or less permanently, so an uncovered crawl space floor is evaporating into the space every day of the year.
In Yemassee the complication is the water table. It sits close enough to the surface that soil under a house can be saturated with nothing broken, so this work is usually dealing with moisture arriving from below rather than from a failure inside the house.

Why it is worth dealing with now
The gap between a drying job and a structural repair in Yemassee is usually measured in seasons, not years.

Vapor barrier in Yemassee: common questions
Will a barrier stop water that is already getting in?
No. A barrier manages soil moisture and vapor, not liquid water under pressure. If water is entering the space near Big Survey Lake, drainage comes first or the sheeting simply floats on it.
There is already plastic under my Yemassee house. Is that enough?
Often not. Most of what we find has been laid loose, has torn, or was never sealed at the seams and walls. Unsealed sheeting performs much closer to bare soil than to a finished barrier.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Yemassee call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Yemassee property changes that.
Why is my Yemassee crawl space wet when nothing has leaked?
Near Yemassee that is the normal pattern rather than the exception. At around 43 feet on the coastal plain, the water table sits close enough to the surface that soil under the house can be saturated with no pipe broken.
I already have plastic down there. Is that enough?
Often not. Most of the sheeting we find has been laid loose, has torn, has pulled away from the walls or was never sealed at the seams. Unsealed, incomplete sheeting lets ground moisture track around and through it, and performs much closer to bare soil than to a finished barrier.
