Before and After Pictures from Ashburn
Ashburn VA- Condensation On Ducts

Ashburn VA- Condensation On Ducts Ashburn VA- Condensation On Ducts

The customer called s because they had a condensation problem with the ducts in their 1st floor town house family room.  This home, typical of many town homes in Ashburn, with a 2 car garage to the front of the home, and a family room tucked behind it. 

The problem was a clear air pathway from the space over the garage to the cold ducts in the ceiling above the family room.  We had to seal the rim joist to the exterior, and create an air barrier with silverglo foam block between the garage and the family room. 

The results were instantaneous, and this Ashburn home owner now has a house that is air sealed and does not sweat.

 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!!!

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.

Home Insulation Services You Can Trust!

Comfenergy is Nova's preferred home insulation and air sealing services company. We have helped many homeowners not only reduce their home energy bills but improve the overall comfort of their homes without patented home insulation solutions.  Did you know that most modern homes do not have adequate insulation? Because of this, your home may feel drafty or uncomfortable throughout the year, mostly in the summer and winter, and this can increase your home energy costs. Proper insulation in your home allows your heating or air conditioning systems to work more efficiently which will save you money. 

We offer a wide variety of home insulation products and services, and each one serves its own unique purpose.  Our most popular form of insulation is spray foam.  Spray foam insulation is extremely versatile and can be used almost anywhere in your home.  Spray foam insulation is one of the best ways to lower energy costs, sometimes 30% or more!

Along with spray foam, we use many other different types of insulation as well. Some of our other insulation products include rigid foam, blown-in, cellulose, fiberglass, radiant barrier, and much more.  We understand that insulation is only part of the home energy and comfort equation, so because of this, we can insulate any area of your home.  We insulate spaces such as attics, basements, crawl spaces, walls, floors, garages, and much more.  If your home is uncomfortable or energy bills are too high, contact us today for a FREE home insulation quote!

Expert Spray Foam Insulation Company

At one point pink fiberglass insulation was the best option for home insulation. However, today spray foam insulation is the much better option. Spray foam insulation has several benefits and beats the traditional fiber-glass product in every way. Spray foam insulation is the top choice for homeowners, contractors and building scientists (the experts who study home energy performance) for several reasons. Here are the top reasons spray foam insulation should be your number 1 choice:

Advantages of Spray Foam Insulation Include:

  • Provides both insulation and air sealing; air sealing is excellent because the foam expands to fill gaps and cracks.
  • High R-value -about R-7 per in. depending on the formulation.
  • Speedy installation. Foaming can be done in a fraction of the time it takes to cut, fit, and seal rigid board insulation.
  • Once cured, spray foam insulation stays in place; it won't shift, settle, or fall out of place.
