Crawl Space Repair Before & After Photos

This home in Herndon VA had a crawl space that had become very nasty over the years.  Uncontrolled air flow lead to humidity issues and excessive moisture.  The failed insulation was leading to cold floors above in the winter and the musty smell from the crawl space was noticeable in the rooms of the home above.  Our team was able to clean out the old insulation, level out the dirt floors, close off and air seal the vents to outside and then properly insulate and seal the rest of the crawl space.  Improved air quality in the home above and reduced energy use were the results.  The crawl space is now clean and safe to use for storage if needed.  

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 Herndon, VA home had a need for crawl space improvement.  Improved insulation and sealing the crawl space off from unconditioned outdoor air was the solution identified by our sales pro who inspected the home.   The production crew removed the old ineffective insulation. After that, they applied spray foam insulation to the rim joists to help make sure that the rooms above the crawlspace were able to maintain a normal temperature. Finally, the crew installed spray foam on the crawlspace walls as the primary form of insulation to keep the home comfortable year-round.

This dirt floor, uninsulated crawl space was transformed with our CleanSpace encapsulation system.
