What crawl Space Vapor Barrier Installation involves in Sharon 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 piedmont and upstate ground
On clay the ground under a Sharon 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 Sharon 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
Nothing about a damp Sharon crawl space improves on its own. The space is enclosed, shaded and over soil — all three work against it drying out.

Vapor barrier in Sharon: common questions
There is already plastic under my Sharon 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 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 Caldwell Lake, drainage comes first or the sheeting simply floats on it.
Will my Sharon crawl space dry out if I open the vents?
Usually not. For much of the year the air around Sharon 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 Sharon property changes that.
What should I have ready when I call about my Sharon home?
Your street in Sharon, 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.
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.
