Decreased cold drafts for homeowner in Herndon, VA Decreased cold drafts for homeowner in Herndon, VA

This home in Herndon, VA was experiencing cold drafts this winter and found it expensive to keep their home warm.  In the attic there was very little insulation and had a low R value.  We used our TruSoft Blown-in Insulation resulting in a less drafty and more comfortable home.

The homeowner in Herndon, VA called because his insulation in the crawl space was falling down.  First, we removed the nasty batt insulation that was falling down and disposed of it all properly.  Then, we installed SilverGlo foam board insulation around the perimeter and installed CleanSpace anti-microbial vapor barrier on the floors. The CleanSpace is held in place with tape in some sections, and foam spray in others.

The CleanSpace is held in place with tape in some sections, and foam spray in others.

The result is now the floors above the crawl space are nice and cozy warm in the Winter.  During the Summer months, there will be less heat and humidity under the floors. Thus, less mold/mildew odors to penetrate into this Herndon home's air.  Thus, making the  indoor air healthier for these Herndon residents.

Good Afternoon, Super concerned about my garage area which is directly below the master bedroom. Hot in the summer and cold in the winter, I don't believe it is adequately insulated or able to stop the cold/hot air from invading the upper level bedroom. Thank you, Dean
