About us
GSI Foundations was established in 2003 and although basement repair is our primary focus, we have extensive experience with all aspects of the rehab process. Realtors, investors, and homeowners have found that having us on their team has been a great advantage for winning clients, purchasing properties, or just taking care of the home they love.
