We will tell you if crawl Space Vapor Barrier Installation is not what your Sycamore 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 Sycamore 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.
Around Sycamore the water usually arrives in storms rather than steadily. That changes what this work is up against: a lot of water in a short time, then a humid stretch afterwards that keeps the space from drying.

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

Vapor barrier in Sycamore: 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 Tutens Millpond, drainage comes first or the sheeting simply floats on it.
There is already plastic under my Sycamore 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.
Do you cover all of Sycamore?
Yes — Sycamore and the surrounding part of Allendale County, including the 29846 area. We also work in nearby Ulmer, Allendale and Fairfax.
Why is it dry in winter and wet by late summer?
Humidity rather than a failure. An enclosed space under a Sycamore floor tracks the outside air, and by August that air has been wet for months.
Can grading and gutters fix it without a pump?
Sometimes, and it is worth checking first because exterior water is cheapest to deal with. Around Sycamore, roof water and a slope feeding the foundation explain a lot of the calls we take.
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.
