    Utility Room air sealing-Sterling, VA

    This Sterling, VA homeowner had a utility room that backed up to their garage.  There was a lot of air leakage allowing cold air to travel through the utility room and into the basement making it cold in the winter. 

    Thermax foam boards and one part foam was used to seal this air leakage off, and to keep it safe from flammability.  Thermax is a fire resistant material.

    Cold Storage Area-Sterling, VA

    This Sterling, VA homeowner had a nice storage area beneath the stairwell that is adjacent to their garage. The cold garage air made this room very cold int he winter.  Comfenergy used Thermax foam boards and two part foam to air seal it and make it warm to put to better use! 

  • Fiberglass versus Spray Foam-Leesburg, VA

    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.

    Top plate air leakage-Centreville, VA

    Top wall plates allow heated air to escape from your home during something called the "stack effect".  This contributes to higher than necessary utility bills, draftiness in the home, and dusting too often. The following before/after pics show how Comfenergy seals these leaks using one part spray foam.

  • Metal chimney wrap-Centreville, VA

    Metal chimney wrap-Centreville, VA

    Metal (and brick) flue pipes and chimneys can get very hot when furnaces, water heaters, and fireplaces vent through them.  Insulation should not touch these assemblies due to the possibility of fire in the attic of the home. Comfenergy wraps these flues and chimneys with rock wool fire resistant insualtion before blowing new TruSoft cellulose insulation into your attic.

  • Basement Insulation in Purcellville, VA

    Basement Insulation in Purcellville, VA

    This Purcellville homeowner was looking for a great way to insulate the basement and have it prepped to finish before putting it on the market for sale.  They didn't want to finish the basement completely, but wanted it "ready to finish" so the buyer could build it out as the wished.

    Comfenergy found the ultimate solution by using Basement to Beautiful wall panels. These wall panels are insulated with SilverGlo foam and have the metal studs already built into them.  Each insulated Basement to Beautiful wall panel is held in place with foam spray insulation, and then secured using long bolts. There are 3 distinct advantages to these wall panels. 1) Once they are installed, the room is ready to be finished because the framing is built in. 2) They provide moisture intrusion control. 3) The Basement to Beautiful panels are infused with anti-microbial materials and will not mold nor mildew.

    Can Light Cover-Hume, VA

    Can lights leak air from you home into the attic (which is outside your home).  It's very similar to leaving the windows open 24/7/365 even when heating and cooling the house.  You are paying for that heated and cooled air.

    Rock wool can light covers not only seal this heated and cooled air in your home, and preventing it from leaving.

    It keeps any flammable materials away from the can light which can reach temperatures allowing wood and certiain types of insulation to catch fire!!!

    Basement Humidity Control-Jeffersonton, VA

    This Jeffersonton, VA homeowner has suffered from high humidity in the basement of their home for years. The basement is attached to a low ceiling crawl space built on a slab. The high humidity is typically caused by:

    1. Drainage of ground water from outside.

    2. Hydrostatic water table pressure coming up from below.

    3. Hot/humid air coming into the basement and hitting cold surfaces.

    These before and after photos show how Comfenergy solved the humidity issue. A perimeter drainage system was installed in the slab around the perimeter of the crawl space. CleanSpace (20 mil) vapor barrier is tucked behind the perimeter drain. Then Thermax foam wall panels are installed to provide the proper air sealing and insulation value. Thermax also provides a thermal barrier for fire protection and meet codes.

    Now the basement and crawl space are nice and dry!

    Replacing Fiberglass Insulation in Amissville, VA

    This Amissville, VA homeowner was looking to lower their utility bills this coming winter.  This before and after pic shows how we removed/disposed of the old fiberglass batt insulation.  Then, newly blown TruSoft cellulose insulation was installed. This cellulose insulation is more densely packed and does a better job at insulating a home than fiberglass due to its quality and ability to reach a high R-value.

    Whole House Fan-Fredericksburg, VA

    Whole house fans are GREAT!!  (For about 2-3 weeks of the year) For our geographic area.  It's way to humid and hot during most of the summer, and way too cold obvisouly in the winter.  During this 45-48 week time period, they do nothing more than allow energy loss in a home.

    The before/after pics that follow show you what Comfenergy can do to allow you to keep your whole house fan for when it makes sense....but not loose energy the rest of the year!
