Our attic insulation process is custom designed to fit your budget.

Your attic, it’s the coldest part of your house in the winter and the hottest area in the summer. You can make your entire home more comfortable and energy efficient by simply increasing the insulation in your attic to the recommended R 50 (or even R 60).

If your home was built before 1980, it may well be under-insulated by today’s efficiency standards. Even newer homes can have as little as R 32 (or less) insulation installed, depending on the builders specifications.

Bringing attic insulation levels up to the recommended standards can result in major savings in the form of lower utility costs. Figures show that upgrading to current U.S. Department of Energy recommendations will reduce heating and cooling costs from 20 percent to 50 percent, particularly if installation is preceded by sealing air leaks.

One of the best ways to seal air leaks along the perimeter of your attic is to use Closed-Cell Spray Foam. This is not the typical Spray Foam that is sold at your local hardware store, that’s OPEN-Cell Foam that moisture can penetrate. Closed-Cell Foam effectively seals air leaks and also creates a vapor retarder to guard against moisture, plus it permanently bonds to the surface to increase the structural strength of your home.
