Taken on its own, crawl Space Vapor Barrier Installation treats one part of the problem. Taken in order, it is the part that makes the rest hold. That is how we schedule it on Lane jobs.
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 Lane 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.
Flood-zone construction around Lane is built elevated, which means newer homes have crawl spaces too. Newer framing, the same conditions underneath.

Why it is worth dealing with now
Nothing about a damp Lane crawl space improves on its own. The space is enclosed, shaded and over soil — all three work against it drying out.

Vapor barrier in Lane: 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 Longlands Hope Swamp Pond, drainage comes first or the sheeting simply floats on it.
There is already plastic under my Lane 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.
Do you work outside Lane itself?
Yes. We cover Williamsburg County broadly, including Salters, Greeleyville and Saint Stephen, and the rest of the Lowcountry and coastal plain of South Carolina.
What should I have ready when I call about my Lane home?
Your street in Lane, when you first noticed it, and what you can see or smell — standing water, a waterline on the piers, insulation hanging down, or a floor that has gone soft. Photographs help.
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 Lane property changes that.
What is the difference between a vapor barrier and encapsulation?
A vapor barrier covers the soil and stops ground moisture evaporating into the space. Encapsulation goes further — ground, walls and usually the vents are sealed and the space is brought inside the building envelope, normally with a dehumidifier to control humidity directly. Encapsulation does more and costs more.
