Rock River Co is a veteran-owned excavation and landscape construction company based in Harwich, run day-to-day by Ken (signed "Ken Beaulieu" in one review), serving customers across Cape Cod. The company's own site describes a full site-work operation — demolition, excavation, septic and sewer installation, pool installation, and landscape design and construction — and its Google reviews back that up with the same range of jobs, from small driveway repairs to full-property overhauls.
Customers who hired Rock River consistently describe the same things: Ken and his crew show up when promised, communicate clearly, and hold to the price they quoted. Several reviewers specifically note the estimate matched the final bill with no overrun fees, and describe him as reasonably or very fairly priced. The work itself draws repeated, specific praise — septic system installation, well and well-pump installation, sprinkler and irrigation systems (both new installs and years of ongoing maintenance), stone driveways, patios, retaining walls, brick walkways, and even a mailbox set on a granite post. One reviewer described a single large project that covered demolishing an old house, removing trees, grading the land, digging for a new septic system, and designing and installing the entire landscape plan — irrigation, plantings, hardscape, and a well with pump — for a newly built home, calling the work flawless from start to finish.
The reviews also cover snow removal and dumpster rentals, both described as smooth and reasonably priced. Several customers say they are repeat or long-time clients who keep coming back for maintenance and new projects.
All 26 Google reviews on file are five stars, and none raise a complaint or quality issue — there's no negative or mixed review to weigh against the praise, and no licensing, BBB, or news record turned up anything to flag either way. That leaves a genuinely clean, if one-sided, record: strong on the fundamentals reviewers care about — responsiveness, honest pricing, and quality hardscape and excavation work. A homeowner considering a larger project, like the septic or full-property jobs described above, has real precedent to point to; for pool installation specifically, which the site advertises but which fewer reviews mention in detail, it's worth confirming recent experience directly.
