A recent Google customer said their new retaining wall, about 50 feet long and 5 feet tall with stone stairs, took 12 days of work, and that Josh is coming back in a few months to help with more yard work. 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.

Josh completed the retaining wall with his stonemason Larry, shown in the photos. Several weeks later, he moved rock fill away from the driveway, delivered and leveled loam across our front lawn, then spread grass seed. Now, several weeks later, we have a beautiful lawn to enjoy, compared to the patchy/lack of grass we had previously. Josh transformed our front yard completely! He listened to our wishes, communicated clearly throughout the process, and delivered a beautiful outcome. He is approachable and takes great pride and joy in executing his work. We are grateful for his time and work and highly recommend him! Thanks, Josh!
Josh did all the site work for our new home, including digging the foundation. He was great to work with from start to finish and made sure everything was done right. The property came out exactly how we wanted, and he was always easy to get ahold of when we had questions. I’d definitely recommend him to anyone looking for excavation or site work.
Josh did a phenomenal job building our new retaining wall! He’s been super easy to work with, flexible, and communicates when he was planning to be around to work. His stonemason Larry also did a phenomenal job with an eye to detail. Now this wall is approximately 50ft long and 5 ft tall so it was a beast, but it looks so much better than the rocks we had before and we know it will help secure our top lawn. The details to the stairs was also incredible when you think about this is stone they need to configure into place. This took 12 days of work 😮 plus a few days after the dirt was delivered. 10/10 working with Josh and he’s already coming back in a few months to help do some more yard work. Thank you, Josh!
I’ve known JJ’s Landscaping and Josh Mastin for many years. Josh has performed several projects for me. Josh has become a master excavator operator. He is very skilled in excavation, wall building, grading and various aspects of outdoor property maintenance. I highly recommend JJ’s Landscaping for new projects and ongoing property maintenance needs.
