I had a great experience working with Abacus Builders. They built me a beautiful roof deck (including roof access and stairs) in South Boston which is an intense project so I was very grateful to be working with experienced and professional contractors. Mark and his team were extremely thorough, paid close attention to detail and enjoyable to work with. They are not only skilled but they are also very good to their customers so my experience was completely stress free and they made sure everything was absolutely perfect for me before they closed the job. I will use them going forward for all of my contracting needs! I have already referred them to friends and would highly recommend working with them.
