  • Working with The Platinum Group was a great experience. From the time I contacted them about getting a quote to the time he finished the project they were always available for any questions I had and made the prices a breeze. They gave us a comprehensive plan and quote They even looked at surrounding areas to advised us of what other items would need to be considered. The office fit us into the schedule and everything was completed on time. They worked personally with us on our stairs and front yard to make sure the job was up to their standards and mine. We plan to use him again for future projects on the yard and we would highly recommend them to anyone looking for a great landscape project experience. They are a company who you can tell he cares about the client and their work!

  • The attention to details on the projects We have worked on is Extremely high. After over 20 years in the industry working in high end markets you can tell the difference between a good company and an average company. The job sites are kept clean (no cigarette butts, food wrappers or misc debris blowing around property) Their workers are professional (no swearing or disgusting behavior) It has been a pleasure to work with them on projects. All of the projects we have worked on the customers were extremely happy with the work.

  • I hired Platinum for a large backyard renovation project, which included a pool, hardscape and landscape. Every experience I had, from the moment I met with the salesperson, to the meetings with the construction manager, were beyond my expectations. The quality of the work performed was more than I ever imagined. I couldn't be happier with the finished product and have recommended Platinum to several friends and neighbors. Thank you for your professionalism!

  • I'm really looking forward to Spring this year thanks to Platinum Site Development's beautiful landscape design at my home in Massapequa. The trees, shrubs and plants installed last year are all healthy and beginning to bloom. I was so satisfied with the design, workmanship and project management that I used Platinum SD again to transform a neglected rental property into a really beautiful home with great curb appeal. (I even enlisted their talented masons to install tile floors, showers and the kitchen back splashes in both homes!) Neither of these projects cost a million bucks, but they sure look like it! Worth every penny!!! I have, and will, continue to recommended your company because of the professional service I received and how satisfied I am with the final results. Thank you, Anthony Lauro, and all of your team at Platinum Site Development, for another job well done. I am looking forward to working with you again soon!
