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.

This home in Ashburn VA had several issues that the homeowner wanted to address, one of which was to make the upper level loft of the home more comfortable year round.  Our Home Performance Sales Pro Eric determined that this could be done by improving the insulation in the attic.  While the attic already had some blown in cellulose insulation covering the attic floor, the walls of the attic were poorly treated and were allowing cold temperatures and air to move into the space.  Eric suggested adding another 6 inches of insulation and to have Silver Glo panels installed on the walls of the attic.  The panels were then air sealed with Zyp Foam to properly protect the space from unwanted air flow.

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:

  • Provides both insulation and air sealing
  • Fills gaps and cracks
  • High R-value
  • Speedy installation
  • Spray foam won't shift, settle, or fall out of place

Crawl Space Insulation Experts

Do you need crawl space insulation installed or replaced? If so, you're in the right place! A damp crawl space with falling or sagging insulation usually means the space has a moisture problem. If that is the case our team of experts can provide a vapor barrier to keep moisture out of your crawl space. We can then replace your existing insulation with a better option such as rigid foam or spray foam insulation. If your crawl space is completely missing insulation then your home is most likely cold and drafty. This is because the environment in your crawl space will transfer to other parts of your home, which is why proper crawl space insulation is essential to keeping your home comfortable and your energy bills low. To learn more about crawl space insulation cost, call, or click today!

Job Stories From Ashburn, VA
Boradlands VA Attic Encapsulation & Insulation

Longtime customer of ours moved into a new home where an inspector flagged the attic for containing poor blown insulation that was providing insufficient containment of airflow and temperature regulation. The customer called us where one of our certified home performance sales pros, Carl,  visited the home for a free estimate. Carl investigated the attic and devised a plan that would help bring the homeowner an attic that would be working efficiently and effectively. Our certified home performance production team removed the old batt insulation and sprayed the attic with Quick-Shield Yeti and Spray Foam to encapsulation the attic. This job helped keep the temperature at its desired set point and provide for a more comfortable home year-round.

Ashburn VA home benefits from spray foam

This Ashburn VA homeowner was experiencing comfort issues in the living space of the home.  Their HVAC system was working harder than they thought it should be causing their utility bills to be higher than they would like.  There were rooms in the home with various temperatures one another and depending on the time of year the homeowner was either too hot or too cold.  Our sales professional Pedro did a full home energy audit and identified several options for solving these problems.  Pedro took detailed notes and set out a plan of action for our production team to execute.  Removing the external cover of a cantilever on the side of the house and administering spray foam to both insulate and seal the space inside would help to keep external air and temperatures from impacting the room it was connected to.  In the attic of the home, we removed some existing Tyvek panels and old batt insulation that was not working the way it was intended and replaced it with more spray foam.  Other areas of the attic were air sealed to keep the conditioned air made by the HVAC system from being able to escape into the attic and out of the home. Once the spray foam and air seal were complete the attic was turned into a conditioned space with would no longer allow the living space of the home to have such fluctuations in temperature from room to room.  The result is a more comfortable home with reduced energy costs.
