On a Tatum job, crawl Space Vapor Barrier Installation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on midlands and sandhills ground
Around Tatum 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.
Humidity does the slow damage here. A Tatum crawl space can be dry in winter and damp by late summer without anything having failed, which is why this work is paired with humidity control rather than ventilation.

Vapor barrier in Tatum: common questions
Barrier or full encapsulation for a Tatum home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Marlboro County property needs should follow a humidity reading, not a preference.
There is already plastic under my Tatum 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.
How quickly does water under a Tatum house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Marlboro County that window is shorter in summer than in winter, because the space stays warm and humid.
What should I have ready when I call about my Tatum home?
Your street in Tatum, 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.
Do you cover all of Tatum?
Yes — Tatum and the surrounding part of Marlboro County, including the 29594 area. We also work in nearby Mc Coll, Clio and Bennettsville.
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.
