We worked with the great team at Abacus last fall to put a roof deck on our home in South Boston. Mark was very responsive in providing a detailed quote and quickly began the project as soon as permitting allowed. The general contractor on our job was Gerald McGuigan and I truly do not think there is a more patient or reachable contractor in the City. We had a few minor glitches with regard to the length of time it took to complete the project but in fairness some of the delay was due to additions and changes in the design that we made. We are now a year post deck completion and the great team at Abacus continues to respond to our questions and help with minor tweaks. We highly recommend this amazing company!
