This Sterling, VA homeowner called us out to lower his energy bills, but we couldn't get into the attic because there was no access. We cut the drywall and created a new access with trim.
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.
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!
This attic had some outdated fiberglass batt insulation that was damaged, moldy, and wet.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.
To fix the comfort issues occurring on the top floor of this home, our team reinsulated the attic with both cellulose and spray foam.
