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 Iva 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 Iva 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 Iva 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
The cost of this work does not stay flat. Every season a Iva crawl space stays wet moves more of the job from drying towards framing repair.

Vapor barrier in Iva: common questions
Barrier or full encapsulation for a Iva home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Anderson County property needs should follow a humidity reading, not a preference.
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 Secession Lake, drainage comes first or the sheeting simply floats on it.
Do you cover all of Iva?
Yes — Iva and the surrounding part of Anderson County, including the 29655 area. We also work in nearby Starr, Lowndesville and Anderson.
Is crawl space water damage covered by insurance?
It depends on the cause, not the address. A burst pipe in a Iva home is commonly covered; groundwater, long-term seepage and flooding usually are not, and flood damage generally needs separate cover. Photograph everything first.
My house is on a slope. Does that make it worse?
Usually. Water landing uphill of a Iva house travels along the clay to the foundation, so intercepting it uphill often does more than extra pump capacity underneath.
What is the difference between a vapor barrier and encapsulation?
A vapor barrier covers the soil and stops ground moisture evaporating into the space. Encapsulation goes further — ground, walls and usually the vents are sealed and the space is brought inside the building envelope, normally with a dehumidifier to control humidity directly. Encapsulation does more and costs more.
