What crawl Space Vapor Barrier Installation involves in Startex 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 Startex 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 Startex. 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.

Vapor barrier in Startex: common questions
There is already plastic under my Startex 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 Silver Lake, drainage comes first or the sheeting simply floats on it.
What should I have ready when I call about my Startex home?
Your street in Startex, 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 Startex?
Yes — Startex and the surrounding part of Spartanburg County, including the 29377 area. We also work in nearby Wellford, Lyman and Duncan.
Is the damage sudden or gradual here?
Gradual, mostly. Around Startex it arrives in steps — a little with each storm — so by the time a floor feels soft upstairs the framing has usually been damp for a while.
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.
