What crawl Space Vapor Barrier Installation involves in Lexington is the same as anywhere. What differs is the condition it is dealing with, and that is set by the ground the house sits on.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on midlands and sandhills ground
Around Lexington the soil dries at the surface and stays damp below, which makes a bare crawl space floor deceptive: it can look dry while still feeding moisture upward. Sealing the ground is what stops that, and the seams and pier wraps are what make the sealing real.
Near Barr Lake and the lower ground around Lexington, this work usually has to account for both surface water in storms and soil moisture the rest of the year.

Why it is worth dealing with now
A crawl space problem in Lexington is not self-limiting. The conditions that created it are still there, and they are still working.

Vapor barrier in Lexington: 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 Barr Lake, drainage comes first or the sheeting simply floats on it.
There is already plastic under my Lexington 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.
What should I have ready when I call about my Lexington home?
Your street in Lexington, 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.
Do you cover all of Lexington?
Yes — Lexington and the surrounding part of Lexington County, including the 29072 area. We also work in nearby Springdale, South Congaree and Irmo.
Why is it dry in winter and wet by late summer?
Humidity rather than a failure. An enclosed space under a Lexington floor tracks the outside air, and by August that air has been wet for months.
Should the crawl space vents be closed?
It depends on your climate. In humid regions, open vents often bring in air that is wetter than the crawl space, which deposits moisture on cool surfaces instead of removing it — so sealing vents and controlling humidity mechanically usually performs better. In drier climates venting can work. This should follow readings, not a rule.
