Chimneys and stone are the two halves of Salguero Masonry's work — chimney construction and repair on one side, hardscape like stone walls, patios, walkways and retaining walls on the other. The Waltham company says it has been in business since 2003, 23 years, and that the owner works on every project personally. Its Better Business Bureau profile has been accredited since 2010 and carries an A+ grade. BuildZoom shows eight permitted projects under the company name. On Google the page averages 3 stars across six ratings, and a February 2023 review gave five stars with the words "Friendly & Respectful." Three things belong on the table before you sign. The state registry shows the company's Massachusetts home improvement contractor registration, #190989, as expired. Violation Tracker lists a 2020 federal wage-and-hour violation by Salguero Masonry Corp carrying a $65,016 penalty. And an OSHA page tied to the company describes a scaffolding fall-protection violation — employees more than 10 feet above a lower level were not protected from falling. For a chimney rebuild or a bluestone patio in Waltham, Belmont, Watertown, Lexington or the towns out toward Concord and Weston, this is a long-established local masonry shop with a permit history you can look up. Confirm the registration is current before work starts, ask how the crew rigs and protects scaffolding on a chimney job, and get references from recent hardscape customers.
