Insulation Installation

Discount Energy Services provides you attic insulation in Northern Virginia to keep your home cooler during the summer and warmer in the winter. Whether you have a newer home or an older home, our insulation contractors can replace or install new insulation that is more efficient.

Attic Sealing

Let our energy-conservation specialists seal leaks and gaps in your attic or crawl space with fire and heat resistant foam insulation to make your home most energy efficient.  Also, if needed, we can remove old insulation and seal out pests with a pest blocking foam, in conjunction with your new insulation.

Having the right home insulation can save you money on your heating and cooling. Older homes may only have a thin layer in the attic and walls, which can let cool air out and warm air in during summer, and warm air out and cool air in during the winter.  As professional insulation installation contractors, we can easily add insulation inside your walls using just a small hole. New types of heat resistant foam insulation and other types such as Silver Shield radiant barrier installed in your attic or crawl space block the sun's heat and help regulate the temperature in your home.
