Bedford County Vapor Barriers
Vapor Barrier Installation in Shelbyville, TN
The Duck River bends right through town, and the vapor barriers Shelbyville crawl spaces have under them deal with that damp river air every summer. Prince Insulation puts down new barriers across Bedford County: full-floor poly, taped seams, wrapped piers, edges up the foundation.
We work out of Decherd and have been in the insulation trade since 1980. If you want to read first, start with our vapor barrier service.

Duck River Humidity and Shelbyville Crawl Spaces
Shelbyville sits low along the Duck River, and the air in town carries that river all summer. Warm, wet air drifts into a vented crawl space, hits the cooler dirt and ducts, and leaves its water behind. Add the moisture rising out of the ground and the underside of a house can stay damp from May to October.
Crawl space moisture control in Shelbyville starts there. A barrier on the ground cuts off the half of the problem coming from below. The other half, the air, is what a dehumidifier handles.
Scheduling Barrier Work Around Celebration Week
Anyone who lives in Shelbyville knows late August. The Tennessee Walking Horse National Celebration fills the town through Labor Day weekend, and getting a truck and trailer across it gets slow. We schedule vapor barriers Shelbyville homeowners order around the Celebration when we can, so it is easier on everybody.
The job itself does not change by season. Clear the debris, roll out the poly, overlap and tape every seam, run the edges up the block, wrap the piers. That is how vapor barrier installation should look in any house in Bedford County.

Older Pencil City Homes and Torn Ground Sheets
Pencil City has plenty of older houses on crawl spaces, from the factory years and before. If there is plastic under yours, it may be thin, brittle, and torn. Many of the old vapor barriers Shelbyville houses still have are done. A crawl space vapor barrier with holes in it is mostly decoration.
When the space is wet enough that a barrier alone will not keep up, we recommend sealing it. Crawl space encapsulation adds a 10 mil liner up the walls, wrapped pillars, and R10 closed-cell foam on the foundation. Here is how that work goes on Shelbyville encapsulation jobs.
A Barrier and Dehumidifier Pair for Muggy Bedford County Summers
For some Shelbyville homes, the right answer sits between a plain barrier and a full seal. Cover the ground, then add a dehumidifier under the house to pull the summer air down. That combination is solid crawl space mold prevention for houses that stay muggy into fall.
Floor, Attic and Foam Work on the Same Shelbyville Visit
Once the crawl space is dry, the rest of the house is easier to fix. We can re-insulate the attic with blown fiberglass or spray foam, and seal the rim joist with closed-cell foam from one of our three rigs. One company, one schedule.
