Recent Projects

When the homeowners bought this Glastonbury home, it needed new life. The windows and doors were old and inefficient, the siding was wood and needed expensive maintenance, and the roof was just plain worn out. We installed energy efficient doors and windows, maintenance-free vinyl siding, and a protective roof to renew their home.
