MJM Masonry

MJM Masonry has been doing brick and stone work out of Arlington, Massachusetts since 1992, working on both residential and commercial jobs — chimneys, retaining walls, patios, brick veneers, and restorations. Trade publications have listed the company as the masonry subcontractor on commercial projects for firms including The Middlesex Corporation, most recently reported in 2022, and in an October 2023 article NBC Boston quoted owner Mark McCullough warning homeowners about scope creep on renovation projects. Its Massachusetts home improvement contractor registration, #132984, is active on the state registry. The company's website also states memberships in the Associated Builders and Contractors and the National Safety Council, and says its crews carry OSHA 10 or OSHA 30 safety training. Procore Construction Network lists the business as Woman-owned with a Women's Business (WBE) certification and a Prevailing Wage classification; a March 2026 Reddit thread recommended the company, describing its owner as connected to the TV show This Old House. One thing worth asking about directly: a web listing reports that the company was the subject of an OSHA inspection resulting in 4 citations and $14,700 in proposed penalties. This is a fit for chimney, retaining wall, patio and brick restoration work backed by a long local track record — ask about the OSHA citations, and confirm the current project scope, insurance and a written estimate before signing.
