Frozen Pipes in Ashburn, VA

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!!!

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.

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

Most homeowners believe their attic has enough insulation but once we explain how much insulation is actually needed to make your home efficient people understand that they don’t have anywhere near enough. It is common knowledge that hot air rises which is why a properly insulation attic is one of the most important things you can do for your home. By adding attic insulation to your home you are guaranteeing to save money and also have a more comfortable home.

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!

Master bedroom and bathroom on 2nd floor get hot during late afternoon and AC can't keep up. Master bathroom is above garage and under attic, which I suspect contributes to the heat issue.

Hello, we have a 2x4 foot area of our attic that is missing insulation. I believe that the missing piece is up in the attic and just needs to be moved. Is that something you can assist with?
Vicinity of Potomac Dr. in Ashburn
I'd like someone to take a look at the attic insulation in my (older) home-- it's a blow-in, and at least 50 years old-- so wondering if it might contain asbestos. And if so, cost of removal and possible replacement. Thanks!
Vicinity of Timber Ridge Ter in Ashburn
We have a 3rd floor condo with west facing windows. Summer time in the afternoon the AC cant keep up with cooling the house and will literally run 24hours a day just to keep the home at 78degrees. I have tinting on the windows and blackout shades but still have issues. Winter time heating is able to warm the house, but I feel like it cuts on far too often rather than retaining the heat. I'm assuming the attic needs to be re-insulated or have additional insulation put in. The total space for my condo is 925sq feet and we are the top unit. As well, not sure what can be done about this but we have a register(maybe the wrong term) that leads directly out to the furnace to help with recycling the air. During the winter, the entire floor anywhere near the register is ice cold due to the draft from the outside going through the house. I was told there isn't anything that can be done but I'd be curious about that too.
