Damp air under the floor ends up in the rooms you live in
A crawl space with a bare dirt floor and open vents takes on moisture from two sides. Water vapor rises out of the ground, and humid outside air comes in through the vents.
Summer air here carries a lot of water. At Clinton's airport, about 9 miles west, the dew point was 65°F or higher in 89% of July hours from 2015 to 2024. Any joist, duct, or cold water pipe under your house that's cooler than that gets wet.
Air from the crawl space drifts up into the house, and the musty smell and the sticky feel come with it. Wood that stays wet grows mold and, in time, rots.
The first things people ask about encapsulation
Something not here? Call and ask Christian.
(501) 550-1115Will encapsulation get rid of the musty smell?
Usually, yes, because the smell comes from damp and sealing the crawl space cuts off the damp. Mold already growing on the wood has to be treated too. That Crawl Space Encapsulation Guy prices mold removal at $1,000 to $2,500, as its own line on your written price.
How long does crawl space encapsulation take?
Most crawl spaces take 1 to 3 days. That Crawl Space Encapsulation Guy needs up to 5 to 7 days when mold, drainage, or wood repairs have to be done first. Your written price shows which applies.
Do I have to leave the house while you work?
No. The work happens under the floor, through the crawl space access door, so you can stay home. If That Crawl Space Encapsulation Guy damages a duct, drain line, or sprinkler line while working, Christian pays to fix it.
Encapsulation seals the crawl space off from the ground and the outside air
Encapsulation is the whole job of closing up a crawl space. A liner, which is a heavy plastic sheet, goes over the dirt floor and up the foundation walls and is sealed. The foundation vents are sealed shut so humid outside air stays out.
A dehumidifier goes in only when the crawl space needs one, and not every job gets one. Christian decides at the inspection, and the reason is written on your price.
The aim is dry air under the house. The EPA advises keeping indoor humidity below 60%, ideally 30% to 50%, to keep mold from growing. A field study funded by the U.S. Department of Energy tested sealed crawl spaces in humid North Carolina. They generally stayed below 60% humidity in summer, while vented ones often ran above 80%.
How an encapsulation job goes, from the inspection to the last day
- The $100 inspectionChristian goes under the house and looks at the water, the wood, and the air. The visit takes 45 to 90 minutes.
- A written price within 24 hoursEvery line has a reason, including whether you need a dehumidifier and whether water or wood work comes first.
- Water and wood work, if your price lists itDrainage, a sump pump, or rotted wood gets fixed before the liner goes down.
- Liner down and vents sealedThe crawl space gets its liner and sealed vents, plus a dehumidifier if your price includes one.
- A stop and a written price for any surpriseIf rot, water, or mold turns up once the work starts, Christian stops and gives you a written price for it before doing more.
- Work done, and Christian a call awayA dehumidifier carries its maker's warranty, and Christian's own phone rings around the clock if anything he installed isn't right.
Encapsulation costs $5,000 to $10,000 for most crawl spaces
That range covers the liner over the floor and walls, the sealed vents, and a dehumidifier when your crawl space needs one.
The $100 inspection comes off the job: hire That Crawl Space Encapsulation Guy and the whole $100 is credited. A deposit buys the materials, and you pay the rest in stages as the work gets done.
What encapsulation won't fix on its own
A liner doesn't stop water that's already getting in. Standing water, a plumbing leak, or rain running under the house has to be stopped first. Otherwise the water stays, hidden by the new liner. Rotted joists and mold on the framing don't go away under a liner either. They're repaired or treated before it goes down, or alongside the work. That's why Christian works in one order: water first, wood second, air last. Sealing the crawl space is the air part, and it stays dry only when the water and the wood are handled before it.
Encapsulation isn't pest control or radon mitigation, and That Crawl Space Encapsulation Guy doesn't do either. The Arkansas Department of Health recommends a radon test for every home.
Work that often goes with this
Will encapsulation help my heating and air conditioning?
It can. In a field study funded by the U.S. Department of Energy, homes with sealed crawl spaces used at least 15% less energy for heating and cooling. That Crawl Space Encapsulation Guy seals the vents on every encapsulation, so the ducts under your floor sit in drier air.
Will it fix my cold floors?
It helps, because sealed vents keep winter air from blowing under the floor. Floors that still feel cold may need the crawl space walls and rim joists insulated. That Crawl Space Encapsulation Guy prices that at $800 to $2,500.
Will an encapsulated crawl space help when I sell my house?
It can. A buyer's home inspector goes under the house, and damp dirt, rot, or mold there ends up in the report. That Crawl Space Encapsulation Guy's written price gives each repair a reason, so both sides of a sale have a number to work from.
My crawl space looks dry. Do I still need encapsulation?
Not always. That Crawl Space Encapsulation Guy gives every line of the written price a reason, so you see why each piece of work is there. The $100 inspection takes 45 to 90 minutes under the house.
