An entire corner of a 110-year-old house had to come down. In a June 2022 review the owners described Bruno and his crew demolishing it, rebuilding the basement foundation underneath, and putting the corner back as it had originally been — recovering and reusing as much of the house's own granite as they could, then reconditioning its twelve-foot fireplace. That kind of old-house masonry is what Boston Foundation Repair is built around. The company says Giuseppe Guerriero, a mason who came over from Italy, founded it in 1989 and that it has worked in Massachusetts for more than 35 years; his son Bruno now leads it with his business partner Carlo, and it also trades as Boston Brothers and BGC. From Cambridge it takes on foundation repair, basement waterproofing, masonry, concrete and crawl space work around Boston and Cambridge. The basement jobs get described in unusual detail by the people who paid for them. A December 2025 customer had the whole interior foundation chipped out at the joints, loose stones reset and the wall repointed. A May 2025 homeowner said Bruno and Cal had worked on their last two houses and waterproofed the basements of both; another that month described precision work, updates along the way, and new stacked stone and stairs at the end. In June 2026 a customer whose foundation was in rough shape said the two owners stayed patient through the permits and inspections the job required. Money gets explained as well as the work. A homeowner writing in September 2023 said the extent of the damage, the repairs needed and what they would cost were all laid out with no hidden fees, and in December 2023 another said basement cracks they had lived with for years were dealt with promptly. Ten Google reviewers rate the company 5 stars, the Better Business Bureau grades it A+ without accrediting it, and its Houzz profile lists masonry and hardscaping work across many Greater Boston towns. If your foundation is old stone and part of what makes the house what it is, this is a crew that rebuilds rather than covers up. Ask who will run your job day to day, whether permits and inspections are inside the price, and — since the business also answers to Boston Brothers and BGC — which name goes on the contract.
The inspection team looked at the cracks, explained the foundation repair options, and delivered great results. Thank you guys!
The workers were remarkably skillful. They worked hard and it's clear that they took pride in what they were doing. They were friendly, courteous, and ready to address my concerns and answer all questions. I would hire them again and recommend them without hesitation.
We had a great experience working with BGC Group on a complicated foundation repair project. From the beginning, Bruno and Carlo were responsive, professional, and patient with all of our questions. The foundation was in rough shape and the project involved permits, inspections, coordination with multiple parties, and unexpected challenges along the way. Carlo kept us informed throughout the process and handled the permitting and inspection requirements, which took a huge amount of stress off our shoulders. What stood out most was their communication and willingness to explain everything clearly. We never felt left in the dark, and they were always available to answer questions and walk us through the next steps. The work was completed successfully, passed inspection, and we felt confident that everything was done properly. Foundation repairs can be overwhelming, but BGC Group made the process as smooth as possible. We appreciate all of the hard work from Carlo, Bruno, and their crew and would absolutely recommend them to anyone needing foundation repair work. - Chelsea & Kevin
I recently hired Boston Foundation Repair for an extensive interior basement foundation masonry repair, and the results exceeded my expectations in every way. The scope of work included chipping out all joints along the entire interior foundation, resetting loose stones, and repointing the foundation walls with fortified mortar. The walls were then finished with waterproofing paint. The repairs thoroughly corrected both structural and cosmetic issues. At the project’s completion, the foundation was fully restored and truly looked better than when I purchased the house. Working with Bruno and Carlo was fantastic every step of the way. Communication was clear and professional, and their knowledge and experience inspired complete confidence throughout the project. The crew was efficient, on time every day, neat, extremely detail-oriented, and highly skilled. Their craftsmanship and pride in their work were evident from start to finish. Bruno and Carlo have completed at least three major masonry projects at my home, and each one has been handled with the same level of professionalism, expertise, and high-quality workmanship. They consistently do a great job. I highly recommend Boston Foundation Repair to anyone in need of masonry or foundation work.
Bruno is always the first person I call. Totally satisfied with his work.
