Nashville's Crawl Space Repair does encapsulation for homeowners across Middle Tennessee — licensed, insured, with the price in writing before the work starts. Crawl space contractors who fix the water before they sell the plastic, and repair the wood that needs it rather than all of it.

Encapsulation under a real house, step by step
Vented crawl spaces do not work in a humid climate. Warm moist summer air entering a cool crawl condenses on the framing, which is why so many Middle Tennessee homes have damp crawls, sagging insulation, cupped floors above and a smell the owners stopped noticing years ago.
Encapsulation only works if the water is dealt with first. A vapor barrier laid over standing water is a liner for a pond, so drainage, grading and a sump come before sealing — any quote that goes straight to the plastic is skipping the part that matters.

FAQ
Under the house: encapsulation questions
What is crawl space encapsulation, and is it worth it?
Sealing the crawl space from the ground and the outside air: a heavy vapor barrier across the floor and up the walls, vents closed, and the space conditioned with a dehumidifier or a supply from the house. In this climate it is the arrangement that works — a vented crawl space in a Tennessee summer pulls in humid air that condenses on the cool framing and rots it. For a house with moisture problems, mold, or high energy bills, it usually pays.
Should crawl space vents be open or closed?
Closed, in an encapsulated crawl space, and it is the encapsulation that makes closing them safe. Open vents were meant to dry the space; in a humid climate they do the opposite, letting in air that is wetter than the space. A vented crawl space with a plastic sheet on the floor is the halfway house that helps a little. Sealed and conditioned is the answer here.
