Niz Masonry Construction & Landscaping

Niz Masonry Construction & Landscaping is a Lynn, MA masonry crew run by Santos Niz Chavez — the reviews are overwhelmingly about stonework: granite and bluestone steps, retaining walls, repointed brick, paver patios. Angi currently rates it 4.8★ from 37 ratings (92% five-star), and Thumbtack shows a completed background check on Santos and 11 years in business. In a July 2026 review, a customer called Santos "a true artist" for hand-selecting and crafting natural stone into a new set of stairs. Reviews going back to 2024 describe the same range of work — a French drain and foundation reinforcement to stop water seeping into a basement, a long retaining wall and two sets of stairs rebuilt front and back, granite steps and a poured concrete walkway replaced in one visit, sod installed for a new lawn. A recurring theme across both platforms is showing up on the day promised and finishing on schedule, even when that meant working through an Easter weekend to beat a neighbor's timeline, as one April 2026 review described. One dissent stands out: in a January 2026 review, a customer on a $19,800 job said she was overcharged, given no clear explanation of costs, and felt talked down to and taken advantage of as a woman. Responding on Angi, the owner denied overcharging and said the extra work billed was outside the original contract and had been agreed to. For masonry work — steps, walls, patios, foundation and drainage fixes — the multi-year record across two platforms backs the crew up; given the one dispute above, it's worth getting a written scope and cost breakdown before work begins.
