I thought a new roof would solve my ice dams. It didn’t, but weatherization did.

Marieta, Homeowner – Gorham, ME

There’s nothing more comfortable than a tight, well-insulated home with even heat from top to bottom. I am glad I didn’t wait.

Al, Homeowner – Bath, ME

I used to sit on the couch in a hat and fleece pullover. Now, this is the house I want to stay in for a long time.

Anne, Homeowner – Rockland, ME

Before we weatherized, even when our living room was warm, our kitchen was cold. Now we can walk around the entire house in our socks, and be really comfortable.

Stuart & Jane, Homeowner – Warren, ME
They insulated all the exterior walls of the house. Our savings in energy should be
in excess of 50%.

Sheila & John, Homeowner – Winslow, ME




Weatherization is helping all of us save on utilities. Our tenant likes it here, likes the savings and, best of all, he’s planning to stay.
