What a full encapsulation covers
- Standing water and drainage dealt with first
- A heavy liner over the soil, up the walls and around the piers
- Vents and gaps to the outside sealed
- A dehumidifier to keep the air dry afterwards
Is encapsulation what your crawl space needs?
Encapsulation closes the crawl space off from the ground and from outside air. It suits a space that is damp but not flooded: soil that looks dark and wet, sweating ducts, a smell that reaches the rooms above, floors that feel cold underfoot. Where water stands under the house after rain, that has to be drained first. Where wood has already gone soft, it has to be repaired. Whoever looks at your crawl space should tell you which of these you have before pricing a liner.
Read what crawl space encapsulation involves, or go to crawl space repair if you already have sagging floors, fallen insulation or standing water.
Water on the floor right now?
This number is for keeping water out of a crawl space or basement for good. A room that is flooding today needs a water damage company. A burst pipe needs a plumber.

Short answers
Does every damp crawl space need full encapsulation?
No. A dry, well-drained crawl space with a little ground moisture may only need a sound vapor barrier on the soil. Encapsulation is for spaces where humid outside air and ground moisture keep the wood and insulation damp.
Who does the work?
An independent local waterproofing company. Kingsport Crawl Space is a referral service and does not do the work itself.
Will I be told a price on the phone?
Usually not. Crawl spaces and basements have to be seen first. What affects the price explains what the company will be looking at.
My basement is wet, not my crawl space. Is this the right number?
Yes. The same companies handle basement waterproofing, leaks and sump pumps.
