Reviews of Abacus Builders & General Contractors (Contractor)

Joe Deveau

Mark and his crew are some of the most reliable and qualified contractors I have used. I am a General Contractor and I go to Mark when I need a business professional that makes me look good. He men are quality and polite business professionals. I have been using Abacus Builders for more then 5 years and plan to continue to use them.

Impressed with the prompt communication and reliability of Abacus. Professional work teams that work with you no matter how small or big the project, show up, get the work done, and clean up well afterwards. Mark's consistent communication via email made working with Abacus seamless. Thanks!

Abacus recently did several renovations on our three family home in South Boston - all of which were very well done. Mark and his team were very professional, fair, always responsive, and did a great job cleaning up after each project.

We had a fire next door and significant damage was caused to our building. Boston Fire came into our building and knocked out most of the windows and doors to fight the fire, ruining most of the building in the process. Abacus did an excellent job repairing the building from a pretty miserable state, and made getting the job done just right their highest priority. Mark and Dave are a truly great team. They are thoughtful people, and did a great job on our building. Luis is definitely the guy you want doing your painting - he take the time as if it was his own home. Highly recommended.

Not enough good words to describe Mark (whom I was a neighbor to for a couple of years) & the Abacus team who developed my townhouse in Southie. Excellent work all around, and whenever any issues arise and I needed help with things that needed to be done at home, work was always of high quality, contractors pleasant to work with and communicative. Highly recommended.

Abacus recently completed a new deck for our condo building on Beacon Hill after also arranging for replacement of our roof by McConomy Construction. The work was very capably performed. Abacus proved to be that all too rare contractor who did not over promise, did the work that they promised, did it when they promised, and did it well. We would engage them again without hesitation.

Mark and the Abacus team are some of the best contractors I've worked with. They put in a 600 square foot roof deck for us on time and mostly on budget (other than special requests we made for materials). They're efficient, timely, and communicative. I highly recommend Abacus for indoor or outdoor projects. Top notch all around.
