  “After a devastating fire next door caused significant damage to our building, we were so relieved to have Abacus step in and handle the repairs. They really went above and beyond, transforming what was a pretty awful situation into a beautifully restored space. Mark and Dave were a fantastic team – incredibly efficient and focused on getting the job done perfectly. And Luis – seriously, he’s a master painter! He treated every detail with such care and precision, as if he were painting his own home. We wholeheartedly recommend Abacus; they were fantastic.” report abuse

  “I absolutely can’t recommend Abacus Construction enough! Evan, Mark, Catrina, and the whole team were fantastic. From the moment I needed help with a water leak and replacing flooring, walls, and paintwork in my new condo, they were incredibly responsive, respectful, and trustworthy. The quality of their work was outstanding – truly a step above the original finishes, and I’m so happy with the results. Thank you so much!” report abuse

  “I’ve been working with Mark and the team at Abacus for several years now, managing properties in South Boston. They’ve been a consistently reliable and professional partner on numerous condo projects – everything from window replacements and siding updates to exterior painting on high-rise buildings, deck repairs, and even complex insurance claim restoration work after burst pipe incidents. What really stands out is their ability to handle larger projects involving multiple trades while working in occupied buildings. Their rates are competitive, and the service they provide is truly outstanding. I highly recommend Abacus.” – Johnna Barry, President Bridge Property Services report abuse

  Mark and the whole Abacus team were fantastic – I was a neighbor of theirs for a couple of years while they built my townhouse in Southie, and I couldn’t recommend them more highly. The quality of their work was outstanding, and they were always so responsive and helpful whenever I needed assistance with home repairs. The contractors they used were great too, really pleasant and kept me fully in the loop. report abuse

  Overall, we were incredibly pleased with Abacus’ work on our condo building. They not only expertly handled the new deck installation, but also coordinated the roof replacement through McConomy Construction. From start to finish, they delivered exactly what they promised – high-quality work, completed on time and to a really impressive standard. We wouldn’t hesitate to use their services again. report abuse

  Mark and his team at Abacus did an absolutely fantastic job with our condo. We had some serious foundation problems – cracked concrete and significant settling – and they completely tackled the structural issues, replacing all the damaged flooring and doors. They were incredibly responsive throughout the whole process, and really went above and beyond with their solutions and recommendations. Best of all, they stayed on budget. We highly recommend them! report abuse
