Vented Crawl Space Door
This vented crawl space door allows air to travel freely into the crawl space. During the summer, the hot, humid air cools, creating a moist environment under the home. During the winter, cold air makes floors cold and pipes vulnerable to freezing.
No Vapor Barrier
The vapor barrier under this home had been removed, allowing ground moisture to evaporate into the crawl space.
Relative Humidity
The relative humidity in this crawl space measured 83%, well above the 60% threshold that creates an ideal environment for mold growth and pest activity.
Mold Growth
Mold was thriving in this crawl space due to the high humidity. Soda blasting will penetrate the wood and remove the roots of the mold.
Efflorescence
As moisture passes through crawl space walls and evaporates, it leaves behind a white, chalky residue known as efflorescence, a visible sign of ongoing water intrusion.
Supporting the Floor
The floor system needed additional support, but the existing shims were an inefficient and unreliable way of holding up the floor joists.
Drainage Matting
The first step in encapsulation is installing drainage matting. This layer protects the liner from punctures and creates a more durable, stable surface for future service access within the crawl space.
CleanSpace Liner
The CleanSpace® liner seals the crawl space floor and walls, helping block moisture from entering through the ground or foundation. Exterior vents are sealed with SilverGlo™ insulation panels and RimTite™ insulation at the joints to create a closed, controlled environment.
SmartJacks
Adjustable SmartJack® supports were installed to stabilize the floor system and lift it back toward its proper position. Because they're fully adjustable, the supports can be fine-tuned during future service visits if any additional settlement occurs.
EverLast Door
The EverLast™ crawl space door creates an airtight seal, preventing moisture and outside air from entering through gaps and compromising the encapsulated space.
