Crawl Space Repair Before & After Photos

This Fairfax VA homeowner wanted to get their crawl space upgraded.  They had excessive moisture which had lead to mildew and mold in parts of the crawl space.  Open vents to outside were allowing air, dust and allergens to come in from outside and were making the air quality of the home poor.  Our Home Performance Sales Pro Jason visited and was able to identify the right products and services to help improve things.  Our production crew removed the old insulation, plastic floor covering and other dirty materials.  They sprayed the space with a botanical cleaner to prevent mold growth, covered the floors with Clean Space, covered the walls with Silver Glo insulation panels, air sealed the panels using Zyp Foam and then used Spray Foam to seal and insulate the rim joists of the home.  

This crawl space in Fairfax VA was wet and nasty with a musty smell.  Open air vents allowed for external weather and temperatures to impact the air inside of the home.  Dust and allergens were passing into the crawls space through the vents as well.  After removing the old insulation and plastic covering the floors, our production team installed a layer of insulation on the ground along with a moisture barrier.  This was followed by covering the floors and walls with Clean Space material and then Spray Foam insulation being applied to the crawl space walls and rim joists.  Eliminating uncontrolled air flow and insulating the space from the outside in helped improve the air quality of the home.  

This Vienna VA home had a major crawl space upgrade including floor covering and insulation, water proofing, spray foam installation and more.  But the final step was replacing the old plywood door with and insulated, tightly sealing Everlast Crawl Space Door.  

This Vienna, VA home Was suffering from an uninsulated exposed crawlspace that was at risk of developing serious water damage and mold growth. Our sales professional Pedro went out to the property to perform his full home inspection and give the homeowner the best solutions to their problems. He found the biggest problems to be the ventilation that allowed uncontrolled unconditioned air to go directly into the crawlspace and the lack of insulation in the crawlspace that, alongside the ventilation, was creating the perfect environment for mold growth and water damage. Pedro explained to the homeowners that the best option to fix these daunting issues would be to fully encapsulate the crawlspace. When the homeowners agreed our services crews went out to the house to get started installing the vent covers and clearing out all the dirt and debris within the crawlspace that was preventing them from installing the new insulation. Then when the obstructions were clear they got to work taking down the old useless plastic tarps that had been the only source of insulation in the crawlspace previously. Finally, the crews got to work installing the CleanSpace insulation system. They started by laying down TerraBlock floor insulation that prevents any moisture underneath from passing through the barrier. Then they installed the CleanSpace cover on the walls and top of the TerraBlock as an additional layer of moisture protection. Finally, they used spray foam insulation on the rim joists to fully encapsulate the crawlspace.

The design of most crawl spaces includes vents that allow air to openly move from outside to in and inside to out.  This allows dust, allergens and even pests to be able to enter the space below a home.  The air in these crawl spaces eventually works its way into the rooms and living areas of the home above.  One of the most common suggestions we make for any crawl space project is to cover, insulated and air seal these vents.  creating a controlled environment in a crawl space by limiting the outside influence helps to improve air quality and the energy efficiency of the space.  Here we used Silver Glo insulation paneling, cut to fit the vent and Zyp Foam to seal around the edges.
