Before & After Photos

A home in Reston, VA had old, yucky, and inefficient insulation in their attic. When an attic isn't properly insulated, several issues can occur including uneven temperatures, drafty rooms, and overworked HVAC systems. The Comfenergy team removed and properly disposed of all of the old insulation. Next, they air-sealed the attic floor with spray foam. And, finally, they installed blown-in Cellulose insulation into the attic. Now this homeowner has a more comfortable home that costs less to own. 

This Reston, VA home had comfort issues with rooms that got too hot in the summer and too cold in the winter.  Our sales professional Eric met with the homeowner to perform a full home inspection and find out why and try to identify a solution.  Eric was able to show the homeowners that the primary cause of their discomfort was the attic’s lack of air sealing and low R value insulation. He determined that the best course of action would be to completely air seal and insulate the attic with ZypFoam air sealant and new top-of-the-line TruSoft cellulose insulation. After the homeowners agreed to Eric’s solution one of our service crews went out to get to work on the home. The crew started by removing and disposing of the old ineffective insulation that had been the primary cause of the original discomfort. After that, they applied ZypFoam air sealant to all of the gaps in the attic floor. This sealed any potential leaks that could have led to uncontrolled unconditioned air seeping out from the attic and into the living spaces. Finally, the crew installed the new TruSoft cellulose insulation to keep the home comfortable year-round.

An uninsulated cantilever can lead to cold floors in a home. In a home with a cantilever, the rooms inside can react to outdoor temperatures when air is able to freely pass in and out of the cantilever, resulting in cold during the winter and heat during the summer.  This type of comfort issue can result in higher than needed electric bills if the homeowner is relying on their HVAC unit to solve the problem but turning the heat up or the AC down.  Dense packing the cantilever happens by cutting access holes and packing them with insulation.  

This Reston VA home was uncomfortable for the homeowner year round.  In the winter months the home was too cold and in warmer months the home was too hot.  Our clients decided to go with our recommendation to upgrade the condition of their attic, including removal of the old insulation, removal of and then covering over an existing attic fan hole, air sealing the floor of the attic and then covering it all with blown in Tru Soft cellulose insulation.  This will keep the conditioned air created by the HVAC system in the rooms it is intended to heat or cool and make the temperature of the home more even from one area of the home to another.  It will also help to reduce the energy costs to live in the home.  

This home in Oakton Virginia had a living room that was too cold in the winter and upstairs rooms that we too hot in the summer. Our Certified Home Performance Sales Pro Jason was able to discover how to fix those comfort issues.  In addition to adding a radiant barrier to the attic ceiling, he realized the old insulation needed to be removed so that the attic flooring could be air sealed with Zyp Foam.  After everything was done, the conditioned air inside of the rooms below will now stay there, making the home more comfortable and with more even temperatures.
