A1 Masonry & Construction

A1 Masonry & Construction, based in Burlington and run by a mason named James, handles the full range of stonework and structural masonry — chimneys, foundations, walkways, bulkheads, retaining walls — across towns from Peabody to Cambridge to Stoneham. Recent reviews describe basement and patio work: a finished basement in Peabody praised for attention to detail, and a patio and retaining wall a customer said "exceeded expectations." The deeper track record adds real specifics: in a 2024 review, a 170-year-old home's crumbling foundation was rebuilt with rebar and fully repointed. A 2025 review described a stubborn basement leak diagnosed on the spot and fixed, with the crew walking through the plan before starting. In a 2024 review, a deteriorating bulkhead was replaced within five days of an accepted estimate, including new concrete steps and enclosure. Another 2024 review described a cracked walkway repaired rather than replaced, saving well over half what a full paver-walkway replacement would have cost. One 2024 reviewer said they independently verified the company's license number and insurance before hiring for a basement repointing job. One thing worth weighing: a 2025 review said stone wall work on that property held up poorly and was already breaking down within a year, even though the same review called the brick work on the same job good — worth asking specifically about finish and durability for any stone project. For masonry, chimney, or foundation work in the Greater Boston area, this is a contractor with a long, detailed track record — just get the specifics in writing for any stonework.
