    I've already recommended you to my colleagues. The crew exceeded all of my expections - cleanup was really good as well. I am delighted with the results of my home's cooling efficiency after the job was done.

    Turning Attic into a Conditioned Space - Prince William County, VA

    A home owner in Prince William County, VA wanted to make his home more energy efficient. One of the ways that we helped them do this was by converting the attic into an extension of conditioned space. We did this by installing an average of 3 inch thick closed cell spray foam on the roof and the end walls. This creates a super insulated airtight cap on the top of your home to stop air from leaking out. Closed cell spray foam insulation has a leading R-value of R6.5 per inch and adds to the structural integrity of your roof. Converting this attic resulted in lower fuel and energy bills.
