Case Studies: Jamestown, NC – Vented, Damp Crawl Space Now Dry and Sealed

Friday, September 25th, 2015 By Jaimie Hooker


Challenge

This Jamestown, NC home had open crawl space vents that were allowing humidity to flow freely throughout the space. Over time the humidity had caused the soil to become damp, debris to build up, sagging fiberglass insulation and a deteriorating 6mil. vapor barrier. The homeowners also noticed an odd odor flowing into the living area of the home causing major and embarrassing concern.

Solution

Crawl Space Specialist, Trevor Lord, advised a plan that would meet the homeowner’s needs of eliminating the foul, musty odor while also conquering the moisture problem in the crawl space.

The crawl space team began the correction process by removing the failing 6mil. vapor barrier and soaked fiberglass insulation. The CrawlSeal 20mil. liner was installed throughout the entire crawl space floor and around every pier, completely sealing off the home from the dirt floor below. Unlike the thin 6mil. vapor barrier, CrawlSeal is as thick as a pool liner and antimicrobial. The new crawl space insulation, X-Grade Crawl Space Insulation was installed. The X-Grade Crawl Space Insulation were installed along the crawl space walls and the rim joists, creating an energy efficient crawl space. X-Grade Crawl Space Insulation will never become ruined if moisture were to penetrate the crawl space area.

To rid the homeowners of the musty smell, the Tar Heel dehumidifier was installed. The self-draining dehumidifier is engineered specifically for crawl spaces to keep humidity levels below 55% and prevent mold growth. The Tar Heel dehumidifier also conditions the crawl space air, creating good indoor air quality from the ground up.

The homeowners noticed an immediate change in the upstairs air quality hours after the installation was complete. They are delighted to have a healthy and dry crawl space thanks to Tar Heel Basement Systems.
