As knowledgeable as any GC I have ever worked with, terrific communication, very detailed oriented and their work is of the highest quality. Their proposals are always competitive. Happy to give a 5 star review. I will always recommend them to my clients.

As new owners of an old condo on Beacon Hill, we hired Abacus to fix the mess of a prior unpermitted defective partial rebuild of a large elevated rear porch. The porch is nearly two stories off the ground. The rear of the building is accessible only by a tunnel. The workplace is small and constricted. Working with our engineer’s plans and their steel subcontractor, Abacus did an amazing job promptly and properly completing this complicated project. We greatly appreciate the communication, workmanship, and attention to detail from Mark, Lua, Gerald, Ryan and crew.

Exceptional experience with Abacus! They came in after another contractor abandoned our full gut renovation in the South End. I couldn’t be more impressed with the level of professionalism and expertise they demonstrated throughout the entire process. From the initial consultation, to the completion of the project, Mark and his team were not only knowledgeable in their field, but also incredibly approachable and patient. Their dedication to delivering high-quality results while maintaining reasonable rates was truly commendable. I highly recommend them to anyone in need of construction services and I look forward to the opportunity to work with them again in the future.

Abacus did a project with us last summer, completely redoing our roof and roof deck in Boston's South End. They were extremely supportive during the at times confusing city submission and approval processes, and the end product was excellent. High quality work all around, clear communication, good value compared to competitors, and a shorter project than others had scoped for us. We really appreciate the work!

The team was at my condo daily building the roof deck was awesome. Can't say enough positive things about the crew. However, Abacus gave the ironworkers the wrong plans and they built a spiral staircase for my roof deck and installed it on the wrong side of my house. Abacus refused to take responsibility and when I wanted it moved to the correct side from the original plan I received the "dog at my homework" routine and gave me a rundown of excuses. Mark never bothered to come down to actually see the project once but somehow tried to place blame on me as if I'm in construction. He was rude and unprofessional. Never completed the project. I got the permit from the city that it was approved, even though it doesn't have a gate which the city requires. Don't work with this company.
