A bare dirt floor keeps giving off moisture under your house
The ground under a crawl space is never fully dry. Water vapor rises out of the dirt all year and collects on the wood, the ducts, and the insulation above it.
Much of the ground around Fairfield Bay holds on to that water. The USDA's soil survey describes the Enders soils here as clayey and very slowly permeable, so rain soaks in slowly.
Joists that stay damp grow mold and, in time, rot. The University of Arkansas Cooperative Extension notes that damp crawl spaces let joists absorb moisture, which makes termite damage easier.

(501) 550-1115Do I really need a vapor barrier in my crawl space?
Yes, if the floor is bare dirt. Without plastic over it, ground moisture rises straight into the wood under your house. That Crawl Space Encapsulation Guy checks the floor, the wood, and the air at the $100 inspection, and the whole $100 comes off your price if you hire him.
Is a vapor barrier the same as encapsulation?
No. A vapor barrier covers the dirt floor. Encapsulation also lines the foundation walls and seals the vents, and it costs $5,000 to $10,000 with That Crawl Space Encapsulation Guy, against $1,500 to $4,000 for a barrier.
Will a vapor barrier fix standing water?
No. Plastic laid over a puddle only hides it. That Crawl Space Encapsulation Guy stops the water first, with standing water work at $1,200 to $3,000, and lays the barrier once the ground is dry enough to cover.
A vapor barrier is a plastic sheet that keeps ground moisture out of the wood
A vapor barrier is the plastic sheet laid over the dirt floor of a crawl space. It stops the water vapor rising out of the ground before it reaches the joists, the subfloor, and the ducts.
The barrier covers the floor and stops there. The foundation walls stay bare and the vents stay open, so outside air still moves through the crawl space. That's what keeps the job smaller and cheaper than encapsulation.
A barrier on its own suits a crawl space where the damp comes from the ground: no standing water, sound wood, and the musty smell faint or absent. Christian looks for each of those at the inspection and writes what he found on your price.

What a vapor barrier won't fix, and when encapsulation is the better buy
A vapor barrier doesn't seal the walls or the vents, and it doesn't stop standing water. Water coming in through the walls, rain running under the house, and plumbing leaks have to be stopped first. Mold already on the wood and rotted joists stay that way under new plastic. That's why Christian works in one order: water first, wood second, air last.
Encapsulation is the better buy when humid outside air is the problem. In a field study funded by the U.S. Department of Energy, vented crawl spaces often ran above 80% humidity in summer, while sealed ones generally stayed below 60%. A strong musty smell, sweating ducts, or cold floors point that way. A barrier is also no pest control or radon mitigation, and That Crawl Space Encapsulation Guy doesn't do either.
Work that often goes with this
Does the plastic have to go up the foundation walls?
Not in a vented crawl space. The 2018 International Residential Code asks for the plastic to run at least 6 inches up the walls when the crawl space is sealed. That Crawl Space Encapsulation Guy does that wall work as part of encapsulation, at $5,000 to $10,000.
Is a vapor barrier the cheapest way to deal with a damp crawl space?
Usually, yes. At $1,500 to $4,000 it costs well under encapsulation. That Crawl Space Encapsulation Guy writes a reason beside every line of the price, so you can see why anything more than a barrier is on it.
Can I add encapsulation later?
Yes. A vapor barrier now doesn't rule out encapsulation later. That Crawl Space Encapsulation Guy gives encapsulation its own written price, $5,000 to $10,000 for most crawl spaces, with a reason for every line.
What if you damage something under the house?
Christian pays to fix it. That Crawl Space Encapsulation Guy covers any duct, drain line, or sprinkler line damaged while laying the barrier.
