Comfenergy is the locally owned and authorized Attic Systems dealer serving the entire region of Northern Virginia.

Originally started as an Insurance Restoration and Indoor Air Quality business in 2003, Comfenergy decided to expand their services to include solutions that actually address issues with attic air leakage. Why provide a clean-up service for mold or moisture build-up when the problem isn't actually being addressed?

Comfenergy provides professional attic insulation and air sealing services that are specifically designed to improve the overall energy efficiency, health, and comfort of the home.

Available attic insulation services:

  • Attic insulation - If your home has drafts or irregular temperatures, then your poorly insulated attic maybe to blame. When attic air leaks into surrounding rooms through gaps and cracks, this causes the entire home to be uncomfortable.
  • Attic Air Sealing - Through attic air sealing we close gaps between pipe holes, attic latches and openings, wire openings, and more. This will further protect your home from attic air leakage and promote energy efficiency.
  • Attic insulation Materials - Spray foam insulation, radiant barrier installation, cellulose insulation, and more!
  • Ductwork services - If your ductwork has gaps then the air you pay to treat could be impacted by attic's climate. Ductwork sealing and repair services help to improve HVAC efficiency and ensure a more comfortable home overall.
  • Free estimates - We provide free estimate for all of our air sealing attic insulation services.

Don't let your family home or business building suffer from comfort problems any longer, Comfenergy can help!

Comfenergy Before & After
  • Frozen Pipes in Ashburn, VA

    Frozen Pipes in Ashburn, VA

     The homeowner in Ashburn called,  as last year their pipes froze and they did not want that to happy again.This home i has always had issues with hot and cold spots, and freezing pipes in the winter.  We found cold air in the master bedroom attic to be getting around the batt insulation leading to the bathroom above.  This entire neighborhood of as notorious drafts and hot/cold spots. These homes have also dealt with many frozen water lines. The water lines were freezing almost 20 feet from the exterior of the home! Comfenergy installed 4" thick SilverGlo foam boards with heat reflective barrier on the attic walls.  

    Problem solved!!!  Foam board insulation in an attic keeps the cold air from travelling beneath the bathroom tub and the pipes from freezing.

    The homeowner will be more comfortable in the Summer and Winter.....but it lessened the draftiness of the home, and the pipes don't freeze any more!!!

    Spray Foam Garage Ceiling-Ashburn, VA

    This Ashburn, VA had rooms over the garage that were too hot in the summer.  This is can often be caused by fiberglass batts installed by the builder in the ceiling of the garage.  They fall away from the sub-flooring depleting all thermal insulating value.  This customer decided to remove the entire garage ceiling and use closed cell spray foam to fix the problem.

    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!

    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.
