Testimonials

We picked Designscapes of Long Island to help us with our backyard design and are Beyond elated. Their professionalism and attention to detail was Simply Amazing. We recommend that anybody who is redoing your backyard, front yard or garden. Utilize Dan, the owner of Designscapes, to help plan and construct their project. He was extremely patient, extremely diligent and very attentive to our recommendations and what we envisioned.

I have the highest regard for Dan; he is a consummate professional and will always try to do the right thing in his effort to custom design a beautiful landscape for his clients. Unfortunately, Dan chose to use Cambridge stones and pavers for our job and the result was disappointing, to say the least, as hundreds and hundreds of white dots have appeared on the surface of these stones and have ruined what otherwise would have been a terrific job. Kudos to the Cambridge rep, Chuck who tried to remedy the problem with his own labor, but the majority of white dots remain....End result: definitely use Dan for your job; do not use Cambridge...or any other paving stone company that fails to alert you to the possibility of this occurrence.

“I never write reviews, positive or negative, but I rely heavily on them for companies and products. I decided to write a review for Designscapes of Long Island because of the wonderful experience we had with them. After getting our cesspool replaced, our backyard was a mess. After doing a Google search for my area, we called many different landscapers and had a handful of estimates. The owner Dan came himself to do the estimate and we could just tell that he was so much more knowledgeable than the others. He educated us about roots and gave us so many great ideas. His communication before, during, and after the project was amazing.

“This landscaping company is family owned and it shows in the care they take when planning and executing their landscaping ideas. They went out of their way to enhance the beauty of our front yard and offered services above and beyond what we paid. They have been available to answer all questions. And they follow through to make sure all plantings are doing well. We highly recommend them.”

The Houzz community is celebrated around the world for their superior taste in design and renovation professionals. This year, many of these top-notch experts have been recognized with a coveted Design or Service award – or even both!
