That customer said Josh's stonemason, Larry, worked with an eye to detail. JJ's Landscaping says it has been in business 10 years and lists Newmarket, Durham, Lee and Stratham as its service area. Its website names lawn care, garden design, planting, gravel walkways, tree and shrub care and flower bed installation among its services, and it offers free estimates. A recent customer said Josh completed a retaining wall with his stonemason Larry, then moved rock fill away from the driveway, delivered and leveled loam across the front lawn and spread grass seed. Several weeks later, that customer wrote, they had a lawn where the grass had been patchy, and Josh had communicated clearly throughout. The work reaches past planting beds. A recent customer said Josh did all the site work for their new home, including digging the foundation, and was always easy to get hold of with questions. A recent reviewer who has known Josh Mastin for many years said he has done several projects for them and called him skilled in excavation, wall building, grading and outdoor property maintenance. **Strengths:** - Retaining walls — a recent customer described a 50-foot wall with stone stairs - New-home site work — a recent customer said Josh dug the foundation - Loam and seeding — a recent customer said Josh leveled loam and spread seed - Clear communication — a recent customer said Josh communicated clearly throughout ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Rated 5 stars on Google from 5 ratings _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=JJ's%20Landscaping&query_place_id=ChIJ6SMvCiAIAakRFlmElf4hu_c) — “Google: 5★ from 5 ratings” - Says it has been in business 10 years _(confidence: medium)_ - [Official Website](http://jjslandscapingllc.com) — “Self-reported 10 years in business” - Lists Newmarket, Durham, Lee and Stratham as its service area _(confidence: medium)_ - [Official Website](http://jjslandscapingllc.com) — “Stated service area (self-reported): Newmarket, Durham, Lee, Stratham” - Built a retaining wall about 50 feet long and 5 feet tall with stone stairs for a recent customer _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2xwbUxXZDFiVWhHYTBoMFVWRm1XR0V4ZVdwME9GRRAB!2m1!1s0x0:0xf7bb21fe95845916!3m1!1s2@1:CAIQACodChtycF9oOlpmLWd1bUhGa0h0UVFmWGExeWp0OFE%7C%7C?hl=en-US) — “5★ Josh did a phenomenal job building our new retaining wall!
