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.

Product Profile: SmartJack

The SmartJack is a permanent solution to stabilize sagging floors in crawl spaces. It lifts the floors above the space to reach where they used to be by stabilizing the beams and floor joists. It also reduces any bounciness that might have been felt by a sagging floor. 

How it works: the SmartJack system creates a solid base of engineered fill to distribute the weight of the home. Galvanized steel columns are fitted to length and set on a foot long steel base. They are secured to girders or supplemental beams with top brackets that are adjustable.

Everytime it rains the crawlspace gets a lot of water, foundation issue..
Project Location: Herndon, VA
We moved in over a year ago and the crawl space was far down on our list of to-dos. We had some plumbing issues and while fixing those we really took in how bad the shape of our crawl space is. Ideally we'd like to clean it up, install insulation, and seal it up. We have problems with chipmunks trying to get in and some making it through and ants/spiders all over the place.

Water in semifinished basement
Project Location: Herndon, VA
Hello, I am looking for a quote to fix a slightly leaky basement crack that was previously repaired with epoxy. The crack is about 3 feet long, but the opening where it is leaking is only a few inches. This repair was done long ago (10+years) so it seems it needs touched up. Attached is a picture. It typically leaks slightly at the bottom (not pictured) after a hard rain. Thanks, Max
