Your Home's Structure
Sealing air leaks and adding insulation are a few of the most cost-effective energy-saving improvements you can make in your home. Doing so can cut heating and cooling costs by more than 15%.
An advanced home energy assessment will locate the air leaks (around windows, doors, vents, chimneys, wires, and light fixtures), and sealing those leaks must be part of any insulation job. The home assessment will determine the amount of insulation you have and how much more you need.
