crawl Space Vapor Barrier Installation is rarely the whole job. On a Fair Play property it sits inside a sequence — the source gets established first, and whatever follows depends on what that inspection finds.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on piedmont and upstate ground
On clay the ground under a Fair Play house holds water long after rain, so the barrier is doing two jobs — stopping soil moisture coming up, and keeping the space off ground that stays wet for days at a time.
Around Fair Play the damage tends to accumulate in steps, a little with each storm, rather than arriving all at once. By the time it is noticed upstairs it has usually been building for a while.

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

Vapor barrier in Fair Play: common questions
Barrier or full encapsulation for a Fair Play home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Oconee County property needs should follow a humidity reading, not a preference.
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 Beaverdam Watershed Four Lake, drainage comes first or the sheeting simply floats on it.
Why does my Fair Play crawl space stay wet for days after the rain stops?
Piedmont clay. Around Fair Play, at roughly 814 feet, the ground holds water against the foundation long after the surface looks dry.
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 Fair Play property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Fair Play 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.
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.
