Summit Landscape Construction

Summit Landscape Construction, based in Nashua, has one of the deepest and most consistent written records around: 53 reviews from 2020 through 2026 across six platforms, nearly every one of them five stars, describing complex hardscape and landscaping work. The through-line is difficult sites handled well. A 2026 review described the team removing a hill from a backyard and replacing it with a retaining wall and patio, working through location-specific challenges along the way. Another 2026 review described a large boulder wall built to support a driveway extension, professional and communicative from the initial estimate through final cleanup. Reviewers from 2023 through 2025 describe pool-patio builds, drainage projects that solved serious flooding, retaining walls to stop washouts under a deck, and a tennis court removed and releveled with fresh loam — each time crediting the crew, often named individually (Billy, Frank, Dylan, Evan, Matt, Tami), with prompt communication and creative problem-solving. Several reviewers mention getting 3D renderings during the design phase before any work began, so they could see the finished result ahead of time. The company works across a wide customer base — homeowners doing a single big backyard project, but also a property manager who described using Summit for years across commercial snow plowing and walkway repairs. One reviewer, thirty years in their home with dozens of contractors under their belt, said Summit stood "head and shoulders above every one of them" for professionalism, quality, and care for both their property and their neighbors'. There's essentially no negative account on record here — the one lower-starred entry (3 out of 5) still described being pleased with the finished patio. Given how many detailed, specific, independently-written accounts point the same direction across half a decade, this is about as strong a written record as a landscaping and hardscape contractor gets. For a patio, retaining wall, drainage fix, or full-yard redesign, the record here points strongly toward hiring them, with the main practical question likely being scheduling given the demand a track record like this tends to bring.
