**Rating: 4.2/5** (medium confidence) — from 20 reviews across 4 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.
100% of sentiment-scored reviews read net-positive. Last 6 months: 4 reviews, 0 negative.

## The honest read

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.

**Strengths:**
- Handles difficult permitting — navigated a contested curb-cut approval with the city
- Foundation and addition digs — completed on tight urban lots without delay
- Diagnoses builder mistakes — fixed a driveway collapse caused by prior poor work
- Works tough terrain — cut a gas-line trench through rock and ledge on a steep hill
