Attic Access Installation in Sterling, VA

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. 

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. 

Fiberglass versus Spray Foam-Leesburg, VA

This before photo shows a vertical wall in an attic insulated with fiberglass insulation. This fiberglass allows hot/cold air to travel through it and touch the drywall, thus allowing the heat and/or cold to transfer into the living space.

The after picture shows the fiberglass removed and newly insulated using closed cell spray foam.  This builds a great protective thermal and air barrier and makes the top floor of this home cooler in the summer months.

Mold Treatment- Leesburg, VA

This Leesburg, VA homeowner had mold growing in their vented attic assembly that was causing the family to develop allergies and get sick very often.  Comfenergy discovered this attic mold and treated it with MoldX-2 before air sealing, insulating and providing other services.

These pictures ar eof the mold covered roof joists before and after being treated by Comfenergy with MoldX-2.

Skylight Insulation in Leesburg, VA

Skylights are beautiful, but can increase heat loss/gain tremendously, just like in this Leesburg, VA home. Especially if they are not properly air sealed and insulated on the back side of them in the attic above.
