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 Daufuskie Island jobs.
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 Daufuskie Island 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.
Terrain decides a lot around Daufuskie Island. Houses sit on slopes, and water that lands uphill travels along the clay to the foundation — so interception outside often matters as much as anything done under the floor.

- Barrier carried up and sealed to walls and piers
Why it is worth dealing with now
The cost of this work does not stay flat. Every season a Daufuskie Island crawl space stays wet moves more of the job from drying towards framing repair.

Vapor barrier in Daufuskie Island: common questions
Barrier or full encapsulation for a Daufuskie Island home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Beaufort County property needs should follow a humidity reading, not a preference.
There is already plastic under my Daufuskie Island 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.
Will my Daufuskie Island crawl space dry out if I open the vents?
Usually not. For much of the year the air around Daufuskie Island is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
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 Daufuskie Island property changes that.
What should I have ready when I call about my Daufuskie Island home?
Your street in Daufuskie Island, 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.
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.
