We contracted with Abacus to help us build a new roof deck on our building in South Boston. During the permitting and negotiation process Abacus was incredibly professional and patient while we worked out the details of what we wanted and ensured everything was done by the books. They truly know how to navigate through various city regulations and zoning restrictions. The construction itself was executed to a high degree of craftsmanship and we are thrilled with the results. The workers always showed up on time and were respectful and courteous. Also, their pricing was very competitive relative to the three other quotes that we received. We would definitely hire Abacus again for future work and highly recommend them to anyone seeking to do any construction / rehab / remodeling.
