The homeowners who hire Bruno Guerriero Construction for a crumbling Boston foundation tend to keep hiring them. One customer wrote in January 2025 that he had relied on Bruno for fifteen years; another traced it to 2011, when the crew waterproofed a basement, and then through a walkway, a patio, and a second basement after a move. The company is a masonry and waterproofing outfit serving Boston, Brookline and Newton, owner-operated by Bruno Guerriero with his partner Carlo — Bruno learned the trade from his father Giuseppe, according to the company's site. Foundations are the heart of the work. A June 2026 review describes repointing the brick foundation of a house and garage, with the crew photographing spots the homeowner could not see, such as under a covered porch. In April 2026 another customer had an 1850s fieldstone foundation repaired and repointed, the old floor slabs taken out and a French drain, vapor barrier and sump system put in. A January 2024 reviewer said Carlo and the team refurbished an entire fieldstone-and-brick basement in just under a week, and in June 2023 a Back Bay homeowner had a historic brownstone repointed. It goes past houses, too: a January 2025 review describes a hole found at the base of an 11-foot seawall, inspected within 24 hours, with a proposal sent and a contract signed. Google shows 5 stars across 29 ratings, and the Angi profile holds a 5.0 from nine reviews posted between 2011 and 2018. The Massachusetts home improvement contractor registration, #159570, is active on the state registry, and the BBB page is an A+ with accreditation going back to 2006. On price, go in prepared. A homeowner who collected several quotes for a four-bay concrete garage in January 2025 said this bid came in the highest, and hired them anyway. A June 2026 customer described a straightforward project rate with no hidden fees, so ask for the scope and the number in writing and set it beside whatever else you are quoted. For a wet basement, a failing brick or fieldstone foundation, repointing, or a seawall, this is the crew people call back. Get the drainage specifics — French drain, vapor barrier, sump — written into the proposal, and confirm the schedule before the first day on site.
The workers are true artists. They executed perfect pointing of the brick foundation in my house and my garage. Not only were they skillful, they were professional, courteous, answered all questions and photographed places that were not visible, such as under a covered porch. I am elderly and preferred to skip the crawl space. They were prompted, started work at 6:30 am and wrapped up at 4PM. I was totally satisfied with their work and highly recommend them.
Bruno Guerriero Construction did a fantastic job sealing our leaking foundation against heavy moisture. They managed the hydrostatic pressure, causing our Boston, MA, basement to flood, leaving us with a perfectly dry, stable space.Exceptional workmanship, great communication from the team, and a 10/10 experience!
