Before and After Pictures from Leesburg

Before After
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.

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.

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.

Job Stories From Leesburg, VA
Creating Storage in Attic over Garage

Many home owners in Northern Virginia finish their basements for additional living space.  One of the unintended outcomes of this trend is that there is a shortage of storage space for items like Tax Returns, Christmas Decorations, Seasonal flower arrangement, luggage and the like.  You know, the things you need every now and then, but not that often.

One strategy to create a storage space for these items is to convert the attic space over the garage into usable storage. 

This project will be broken into phases:

1)      Install pull down Attic Stairs to improve access to the storage space.

2)      Install Radiant Barrier to reduce the temperature in the attic during the hot summers of Virginia.

3)      Address the vertical wall that separates the attic space from the conditioned space inside the house.

4)      Install flooring and shelving to create the storage space.

More to come as the project unfolds.

Hi - We quickly need an estimate for remediation of the following home inspection deficiency. Your system won't let me attach the photos, but the text is listed below. The crawl space is 27'x15'x4'; the deficiency is item 4. From the Home Inspection Report of 09/09/2016 performed by Gregory Caudill ) Under Floor and Crawl Space 1. Method of Inspection Observations: • The under floor area was entered and traversed. 2. Floor Area Type Observations: • Gravel is common for crawlspaces 3. Vents Conditions Materials: The type of venting is with perimeter vents. Observations: • The cross-ventilation in the crawlspace appears to be adequate. 4. Insulation Condition Materials: Fiberglass batt insulation is installed. Observations: • The ceiling is insulated blocking view to the majority of the framing components. • The vapor barrier is mounted to the floor joists which can trap moisture between the floor framing and the vapor barrier. Trapped moisture is observed with wet insulation and stains which can have adverse effects to framing, insulation, rot, mildew, etc. The vapor barrier should be installed to the heated side of the framing or to the dirt floor to allow the natural venting to take place. Repair or replacement is advised by a contractor familiar with air and moisture movement.
