The Process

We will arrange a visit to see your home. In some cases, no one is required to be home for the quote.

1. Old Caulking Removal

We’ll meticulously remove old caulking around windows, doors, vents, and pipes. Fresh starts begin with clean surfaces.

2. Install foam backer rod / or *spray foam

We install closed cell foam backer rod to create a nice tight envelope around the window. Then we seal to keep the elements out of your cozy home.
