We will tell you if crawl Space Vapor Barrier Installation is not what your Vance 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 midlands and sandhills ground
Around Vance 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.
Midlands ground drains unevenly. Sand moves water quickly until it meets something that does not, and it then travels sideways — which is why exterior grading gets looked at on Vance jobs alongside the crawl space.

Why it is worth dealing with now
Left alone, a wet Vance crawl space does not stabilise — it keeps feeding moisture into the floor structure until something upstairs gives.

Vapor barrier in Vance: 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 Lakewood Lodge Pond, drainage comes first or the sheeting simply floats on it.
Barrier or full encapsulation for a Vance home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Orangeburg County property needs should follow a humidity reading, not a preference.
Why is it dry in winter and wet by late summer?
Humidity rather than a failure. An enclosed space under a Vance floor tracks the outside air, and by August that air has been wet for months.
My house is near Lakewood Lodge Pond. Does that change anything?
It can. Being close to Lakewood Lodge Pond usually means a higher water table and a longer wet season under the floor, so drainage and a properly sealed barrier matter more here than they would further from it.
Why does my Vance crawl space only flood after heavy rain?
That points to surface water rather than groundwater. Storms around Orangeburg County deliver a lot of water quickly, and when the ground cannot take it fast enough it travels across the surface and in through the foundation vents.
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.
