Lopez’s Masonry and Concrete

Lopez's Masonry and Concrete is a Waltham operation built around one name — Carlos Lopez shows up on nearly every job, and reviewers keep circling back to the same thing: he explains the plan, shows up when he says he will, and does what he promised. The company says it's been at this 15 years, working Waltham, Lexington, Weston, Lincoln, Newton, Arlington, and Watertown. The recent stretch of work reads like a tour of the trade. One customer's patio job left them very happy with the communication and effort. Another had retaining walls, a sidewalk, and a roof power wash finished exactly as promised. A six-day rebuild in Newton swapped a crumbling concrete garage apron for stone, added a retaining wall, and lined the driveway in cobblestone — the reviewer noted the crew was always on time and responded quickly on scheduling. When a different customer's garage floor and foundation were crumbling, Carlos steered them toward pavers instead of poured concrete, pointing out that concrete cracks more in New England winters — the kind of detail that suggests he's thinking past the sale. And when a fall-2025 concrete steps repair developed cracks over the following winter, he came back and fixed it, with the customer confirming they were happy with the redo. That same pattern — retaining walls, concrete and brick steps, walkways, driveways — runs through the longer history too: 58 reviews dating back to 2021 across five sources, Google alone showing 4.9 stars from 97 ratings, and a BBB profile that grades the business A+ even though it isn't a BBB-accredited business (accreditation is a separate, opt-in status from the grade). Worth asking about before booking: BBB lists Lopez's as a one-employee business, so it's Carlos and a small crew rather than a large outfit — good if you want his personal attention on the job, worth confirming if your project needs more hands or a tight deadline. The exact review totals also shift depending on where you look — Google logs 97 ratings while one directory listing shows 64 — so treat those numbers as in the same range rather than exact. For retaining walls, concrete or brick steps, walkways, driveways, or general masonry repair in the western suburbs, Lopez's has a long, consistent track record to point to — just talk through crew size and timeline for your specific job first.
