Frozen Pipes in Ashburn, VA

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

Help Your Home with Attic Insulation

Upgrading your home’s attic insulation is a very effective & popular energy-saving method because there is usually a lot of room for improvement. 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. Not having a properly insulated attic is equivalent to constantly leaving one of your windows open. Don’t wait any longer to learn more about the attic insulation methods we have available in your area!.

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!

Vicinity of Spring Morning Court in Ashburn
I would like to see if I can remedy the draftiness of certain areas in my house - specifically the family room and dining room. The back of the house in general seems to be a problem area. Also, my daughter's room tends have some issues that I think are due to poor insulation and the fact that it gets the brunt of the sun. Last but not least - I believe that I probably need additional blown insulation in the attic. Thank you!
