Sandri Stone

Sandri Stone is a Harrisville, NH dry-stone masonry business run by John Sandri, a stone waller certified by the Dry Stone Walling Association of Great Britain (DSWA-GB) with more than 20 years of experience. The company designs and builds stone walls, patios, walkways, retaining walls, historic stone rebuilds and shoreline stonework for homeowners across the Monadnock region, and its crew holds Stone Trust professional membership. In a December 2024 Google review, a homeowner described working with the crew — named as John, Joel and Ezra — to choose the right antique stone for a custom bench and set it in place, calling the result something they'd enjoy for years. Separately, a 2025 feature from The Stone Trust, the national dry-stone trade association, highlighted John Sandri's craftsmanship on unique and technically demanding projects, including underwater stonework. This is a small, specialist crew best suited to homeowners who want traditional, hand-built dry-stone work — walls, patios and historic stone restoration — rather than poured or mortared masonry, and who value working directly with certified craftsmen on a custom project.
