Venting Bathroom Exhaust Fans in Sterling, VA

Once we created an attic access in this homeowner's home, we found two bathroom attic fans that were exhausting into the attic. In the wintertime, this hot humid air, blowing into a cold attic will create condensation and possibly mold on organic material. We took action and vented them outside of the house through the gable. 

Garage Insulation in Sterling VA

Cold floors in rooms above garages are typically caused by air gaps between the sub-flooring above and the fiberglass batt insulation below. Any time insulation does NOT touch the surface you are trying to keep warm or cool...it will NOT work!

See how big the gap between the floor and the insulation is in this Sterling Virginian Home WOW!!!!  This might have been the worst we have ever seen...Might be 2-3 feet of a gap!

Our team spray foamed the gaps to ensure no air leakage. These floors are now much more comfortable! 

Batt to Cellulose Insulation: R-Value Increase

This attic had some outdated fiberglass batt insulation that was damaged, moldy, and wet. It was not properly insulating the attic due to its conditions and this was causing the top floors of the home to be very hot and humid in comparison to the rest of the home. The solution was to replace the fiberglass batt insulation with cellulose and air seal can lights and other areas of air leakage.

Spray Foam Attic Upgrade

To fix the comfort issues occurring on the top floor of this home, our team reinsulated the attic with both cellulose and spray foam.

Attic Skylight Insulation in Sterling, VA

Sometimes the insulation around the vertical portions of a skylight will fall off or is never installed, to begin with. This allows outside air to radiate through the drywall and into the living spaces below. This can make a home feel uncomfortable in certain areas. Closed-cell spray foam is installed on all surfaces of the skylight chase with an average thickness of 2 inches. This keeps the outside air away from the drywall and lessens airflow into the living spaces below.
