  • CleanSpace Encapsulation System in Herndon, VA - Before Photo

    CleanSpace Encapsulation System in Herndon, VA

    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.

    Crawl Space Encapsulation

    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.

    A Crawl Space Makeover - Nasty to Nice

    This crawl space in Philomont was damp and had little to no insulation. This was causing floors above it to be abnormally cold and the duct work to freeze. In warm months, the duct work would sweat. After our team performed this incredible crawl space encapsulation, the crawl is now totally dry and encapsulated. The floors above will remain warm in the winter, the duct work will no longer freeze/sweat, and the reduced humidity levels will eliminate the possibility of mold growth.

    Remediate Mold and Waterproof Basement in Purcellville, VA

    A homeowner in Purcellville, VA had chronic water infiltration in her basement. This caused mold to grow, because the humidity levels in the basement were consistently over 60% for long periods of time. Mold can cause asthma like symptoms and allergies. 3 Pros Basement Systems crews came in and cleaned up the mold and the wet basement. Then, we took action to make sure it didn't come back by installing a perimeter basement waterproofing system including a new Super Sump Plus.

    Waterproofed Window in Basement

    This set of photos is from a partially sub-terranean window in Vienna, Virginia that has been allowing water into the home for a long time. You can see that is was once a mess and the home owner tried an exterior quick fix, but the second photo shows the window after being waterproofed. Not only was the window waterproofed but so was the rest of the basement which you can find a full series of photos of in our gallery.

    Everlast Window Inserts in Gainesville, VA

    A homeowner in Gainesville, VA had a broken basement window. Until recently, the standards for basement windows haven’t been very high. Builders paid attention to windows in the main part of the house, but typically chose cheap steel or wood-framed windows for the basement. As a result, standard basement windows have some significant problems. 

    The 3 Pros team quickly replaced this window with an EverLast Window Insert. The EverLast Window Insert features double-pane, insulated glass, so you won't need to worry about major heat loss. Our installation crew will use the right techniques to eliminate air leaks through gaps around the window.

This crawl space is now clean, conditioned, and helps make this home more comfortable and efficient.
