    A customer had some stairs that were very squeaky and cold during their morning trips to the kitchen. We caulked and spray foamed the stairs to insulate them from the cold basement and also to provide some sound-deadening qualities. The customers asked us to run and jump on the stairs because they could not believe how quiet they were after we were done. Needless to say, this customer was thrilled with the results!
