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.

Job Stories From Herndon, VA
5 Inches of Standing Water in Herndon, VA Crawlspace

This homeowner in Herndon, VA unfortunately had let the leaky conditions of their crawl space to reach an irreversibly damaged point. When the 3 Pros team was called in, the customer had 5 inches of standing water in the crawl space - and it was the middle of the winter!! One of the main reasons was because the gutters and downspouts of the property were not correctly routed to expel water away from the house foundation. The standing water had caused the floors to buckle and mildew. 

Our crew set up an electric water pump in the crawl space for 2 days prior to servicing in order to properly dry out the space. We installed a much-needed new sump pump and fully treated the crawl space for mold. We also replaced the homeowner's moldy, wet insulation with our spray foam encapsulation.

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
