Kinvara Excavation is a Dorchester-based excavation contractor working around Greater Boston, and the through-line across two dozen reviews is one name: Gerry, who homeowners describe handling everything from foundation digs to sewer-line swaps to permit headaches personally. The company describes itself as registered, bonded, and fully insured, offering demolition, foundation excavation, underground utility work, storm drainage, grading, and land clearing. The recurring story is a homeowner facing a project other contractors wouldn't touch or a city process that looked impossible — a curb cut several people warned would never get approved, a foundation dig for an addition on a tight Boston lot, a driveway that had collapsed near the foundation because of a previous builder's bad work — and Gerry working through it directly, coordinating with the city, adjusting the schedule when problems came up, and finishing on time and on budget. Specific jobs recur across the record: sewer main and lateral line replacements, a gas-line trench cut through rock and ledge on a steep hillside, asphalt and brick removal ahead of a renovation, and a rebuilt infiltration system that passed civil-engineer approval. Several customers mention using the company for more than one project. Reviewers consistently point to fair pricing and clear communication as the reasons they'd call again. For anyone hiring, the record points to comfort with tricky, permit-heavy or physically difficult sites — steep grades, ledge, tight urban lots — more than routine excavation.
