Before & After

Before and after in home performance contracting is much more about the measured results compared to other home improvement projects that place much more value on the aesthetics.

Ways to measure attic air sealing and insulation projects can be done in several ways:

1. Overall comfort for the occupants of the home.
2. Lower monthly energy bills.
3. Blower door air leakage test-in and test-out results.

Understanding how to treat the different problems we face in Maryland homes is the key to discovering whether or not they exist in your home as well.

There is no better way to figure this stuff out then to see the video!
