Case Studies: Walkertown, NC- Nasty Crawl Space Upgraded in Four Simple Steps

Tuesday, July 12th, 2016 By Jaimie Hooker


Mold covering the floor system, intruding water and falling insulation was the usual sight for this Walkertown, NC crawl space. Open vents and a deteriorating access door were allowing water vapor and unwanted pests to completely take over the area. After putting off correcting the problem for a year, the homeowners decided fixing the problem could not be pushed out any longer.


System Design Specialist, Xander Cassat, put the plans in motion after completing a thorough inspection of the crawl space and designing a permanent solution with the homeowners.

In order to eradicate the moisture problem, the team had to fix the ground water leakage that entered the crawl space at the base of the foundation. A shallow trench was created throughout the entire interior perimeter of the home and the CrawlDrain Drainage System was installed. CrawlDrain’s custom engineered design allows for water to collect in the system and flow in the SafeDri triple sump pump without clogging. The SafeDri triple sump pump is able to remove 6,200 gallons of water per hour, keeping the crawl space dry–at all times! In the event of a plumbing leak, the SafeDri™ Battery Backup System would alert the homeowners.

Correction of the ground water leakage allowed for the team to begin the next step, isolating the home from the exposed clay. The exposed soil was isolated using the 20mil CrawlSeal System. Each pier and every interior wall were also covered, preventing water vapor pushing through the cinder blocks to enter the home above.

Preventing outside air from entering the crawl space was completed in two easy steps. Each vent was sealed using the X-Grade Crawl Space Insulation panels, while the deteriorating wooden crawl space door was replaced with access door. Both X-Grade Crawl Space Insulation and door are resistant to weather and humidity, keeping pests and moisture out.

Keeping the crawl space air dry was the last step in the transformation. The Aprilaire self-draining dehumidifier was installed to keep humidity levels below 55% and stop active mold growth. As the mold spores dry out, the musty odor in the living area will subside and the wood will begin to dry.

Tar Heel Basement Systems was able to expunge the main problem, moisture. The results created a healthy environment in the crawl space that would provide proper indoor air quality for the living area above.
