Evan and the Abacus team did a great job on my project. They were proactive, detail-oriented, and very responsive to any questions/requests that I had. I also thought that the pricing was fair, and they were very up front about the costs. I will certainly work with them in the future for any contracting work.


Thanks Mark. Together my plans, your construction expertise has created a house/home that i will live in the rest of my life. The property is constantly receiving many compliments from the neighborhood.

Great experience. Mark and the team at Abacus do great work. I feel lucky to have found a reliable and trustworthy, professional to have on my side with respect to work done in the home.

Contractor was called without prior experience with this company and addressed my concerns of the snow on my roof immediately sending out his workmen within days to clear it. The gutter and stairs were damaged due to the ice/snow and they fixed both issues, the stairs were rebuilt within days and the gutter reinstalled as soon as the weather permitted. I would call Mark without hesitation in the future.

Mark has been doing work for me for more than 5 years now. I have to say he does exactly what he says he is going to do. He is there when he says he is going to be there, and his men are completely professional and the quality of the work is very good. I would not hesitate to give Abacus my endorsement and hardy recommendation.

Abacus Builders has done a wonderful remodeling job for my office and met all my expectations with their knowledgeable and skillful services. Everyone was professional and so pleasant to work with. It was a great experience and we would call on Abacus again without hesitation when next we need to update. Their word was their bond.

Emailed Mark at Abacus to remove ice and snow from my roof. Responded immediately. I could not be any happier with the service we received from Mark and his crew. They worked from the minute they arrived until the job was done.

I was very, very impressed with all aspects of my dealings with Abacus. I highly recommend them!

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

I’ve had very limited interaction with contractors so I didn’t know what to expect, but Abacus was very professional, prompt, courteous, and swift in their work. Arranging a date/time for the work to begin took several back-and-forth conversations over days on account of our busy schedules, but once the time frames lined up the work went quite quickly and smoothly. It was clear their experience showed they knew exactly what to do and how to get it done efficiently. They were very good at making sure I understood what needed to be done, what was going to happen, and confirmed their choices in how to resolve the repairs matched with my expectations. As a homeowner, I’m very relieved to have built a relationship with a firm I now trust and respect. I’ll definitely call Abacus for my future house maintenance and improvement needs.

Abacus Construction has completed two major jobs on our old house in South Boston. First he helped us complete some major interior work reconfiguring the small bedrooms into a master bedroom and a guest room. He built three closets, replaced three windows including a skylight. He also refinished the old pine floors and drywalled the new rooms. He was careful to consult an engineer to make sure that the walls were properly braced. His carpenters were amazing putting in new trim that matched the old trim perfectly, making sure that the character of the house was maintained.

Secondly, Mark came in to complete an outdoor project for us. When our landscape contractor could not finish the job, Mark came in and completed all of the outdoor carpentry right as winter was approaching. He built a fence with a gate and stairs on a steep hill. He had to work in a tight space around a big tree. He also installed a small fence against the house to create more privacy on our deck and added gutters to our shed for better drainage.

In both cases, Mark’s team got all of the work done on time and on budget. He never raised his price and took great pride in the quality of the work. They left the site clean and tidy. They suggested improvements that would be good for us and gladly did it quickly. We had to move in and had only three weeks to get the interior work done and he made the deadline with no problems. We moved into a fully renovated house in less than a month. In the yard, we need to get the fence and gate up before the ground froze and to protect our house. They finished a day early and everything was perfect. Mark is a truly honest and professional contractor who takes pride in doing a good job and meeting a client’s expectations. We would not only hire him again. We would not hire anyone else.

Mark took over the project after I had to fire the initial contractor for the incompetence and failure to complete the job in a timely manner. Mark was fantastic. Mark completed the work in the time frame promised at a reasonable price. Through he had many project he was juggling, he made me feel like I was his only customer. I highly recommend Mark Little and Abacus Construction.
