A rocky, dirt floor crawl was causing humid conditions in the rooms above due to uncontrolled moisture and hot summer weather. To remedy this, the 3 Pros team installed drainage matting and then a wall to wall vapor barrier (CleanSpace) to encapsulate the crawl space.
A homeowner in Herndon, VA wanted to reduce the chances of mold and humidity in their crawl space area. This crawl space was vented, like most homes in our area, and the vents let warm humid air in which is cooled by the subterranean crawl space. This causes relative humidity to go way up and condensation to form all over the crawl space surfaces including floor joists and ducts. Then mold can grow, wood will rot, and musty odors can appear. To address this, the 3 Pros team sealed up the vents and a dimpled plastic drainage matting is installed on the floor to create a thermal break. A heavy duty liner, CleanSpace, is installed across the floor over the matting and up the walls. Finally closed cell spray foam is installed on the walls to the top of the rim joist.
When our team arrived to this job, the crawl space was in bad shape. Fiberglass batt insulation was falling off the ceilings/walls due to being so heavy with moisture. Not only was this making the insulation completely ineffective, it also was a breeding ground for pests and mold. To fix this situation and make the customer's home healthier, we removed the dirty insulation, installed drainage matting and CleanSpace Wallie to encapsulate the crawl space, and applied spray foam insulation to the walls and joists.
This dirt crawl space had lots of moisture issues including mold, mildew, and wetness in the concrete foundation walls. We installed a SmartSump drainage system, SilverGlo insulation panels, and our CleanSpace encapsulation system.
This Lincoln, VA homeowner was interested in several comfort solutions for their home. The lower level floors are always cold in the winter, and seemed drafty. Plus, the house was always humid and clammy.
We evaluated the situation and found crawl space encapsulation would be the best solution.
