What a surprise it was:

I was seeing patients all day Tuesday, when one of them — walking in –commented on how nice it was to sit outside and meditate to the sound of the waterfall. I went outside and — surprise — I saw a working water feature (and later found the manual making me

understand that I have a new pump).

Thank you so very much for solving the problem so rapidly. I truly appreciate your attentiveness

and responsiveness. It is nice to know that I can rely on you not only for the initial installation but

also — for many years to come — on maintaining the beauty you created.

Thanks and best always, Nurit, Southampton NY 2020


“We both wanted to let you know that we are extremely happy with our new deck and patio! It took a little longer than we anticipated, but the results really do speak for themselves. Jerry and his crew did a wonderful job – they worked so hard in some of the hottest weather we’ve had. All were professional and polite, and each day made sure to clean up so that we had usable area for the evening. The patio is gorgeous! Jim and Terrance were amazing! We are so impressed with their craftsmanship and attention to detail. They kept us informed all along the way, asking us questions, making suggestions, and doing everything possible to ensure that we were happy with the results. The completed porch totally exceeds our expectations! And it all began with your design. You listened to us and put our wish list into a plan, which turned into a dream. Thank you, and thank all involved. We really couldn’t be happier! And, we have already recommended Designscapes to others who are planning home projects!” Fred & Bonnie B. Patchogue, NY 2019


To start, we would highly recommend Designscapes! My husband and I were looking for Someone to help us with a few projects on our front yard. We needed a new driveway, walkway, front steps needed work, and some garden work as well as an irrigation system. We were in contact with several other companies with no satisfaction, until we met Dan and Doug of Designscapes. They came over and listened to what we needed, Dan come up with a great design and ideas. The project was worked in stages with Dan overseeing the work every step of the way. He scheduled each step as it progressed, my husband and I did not have to deal with that aspect. His team of workers are top notch! Very knowledgeable, professional craftsmen, we cant say enough about what a great experience it was to have worked with Designscapes and its crew of employees. We have a few more projects that we will be calling Designscapes for. They put my faith back in how a business should be run.

Testimonial Mary 

“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. I NEVER had to track him down or email twice with the same question. Even after our project was complete and paid for Doug continued to answer my questions. The prices are reasonable, but more importantly the professionalism and follow through from this company is like none I have experienced before. Designscapes of Long Island comes with my highest recommendation. We will absolutely be using them for our future projects.”

Jim S., Holtsville, NY

“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.”  Jim S., Holtsville, NY 2018

Michael J., Woodmere, NY

“So the internet can be a tricky place, you hear horror stories from people getting scammed, or just not happy with the company they chose. So you can imagine how hesitant I was, picking a company to do our landscaping when I decided to go “out” of the neighborhood known companies to try and get something different. I stumbled upon Designscapes on Houzz , and after reading all the great reviews decided to set up an appointment with the owner Dan. We met a week later. I was super comfortable with him and hired him to design our landscaping, lighting, and irrigation on the entire property (1 acre) few weeks later. We sat down to look over his Dan’s design and within the first minute both my wife and I looked at each other, nodded and told Dan he has the job. This guy is SUPER talented, he listened to what we wanted to accomplish, and executed a plan that was perfect! The guy killed it. Several weeks after that meeting, his crews began work. What equally amazed us was all his crews were equally professional, always making sure to clean up after themselves on a daily basis, site manager met us each morning to review what they were doing, and on and on. I cannot RECOMMEND Designscapes enough, everyone who passes our house, all neighbors, friends want to know who did this masterpiece. I have referred Dan to 1 family member and 3 friends looking to do work and I will continue to recommend him to everyone. After a few weeks passed, he came back removed all the bushes that didn’t take bc of shock an replaced without us even saying a thing. We love these guys. Use them, do not be scared bc you found them online. You will not be happier with the results. THANKS DAN!!!!! ”  Michael J., Woodmere, NY – 4/2019

“Dan was a fantastic help in a project we recently did. It was a bit complicated and we needed to work around a spa that was being installed. He made it happen. Many thanks to Dan and his team.” Jay E., Westhampton Beach, 


Lou B. Lake Grove, NY

“We recently renovated our home which of course made the front yard look old and tired. Dan was able to create a design that has accentuated our house. His team was able to execute in a very professional manner leaving us with a beautiful yard and nothing but praise for Dan and his team.”  Lou B. Lake Grove, NY – 

Susan M., Farmingville, NY

“Dan had just finished landscaping my brother’s back yard and it was beautiful, so I decided to call Dan to help with my backyard as well. I was very particular and wanted a different look from my brother. Dan sent me some proposals and we went back and forth changing the look etc. Finally I decided to go ahead even though I felt it was a little expensive, I just wanted it complete.

I came home last night walked through my back gate and I almost screamed…it was magnificent way beyond my expectations!!! I am so thrilled with the outcome that I have decided to do over my front landscaping as well. Most importantly, I feel the price of the job was well deserved!!! I can not wait to see what he does with the front yard!!!

Thank you to Dan and his wonderful crew, my house was left immaculate as well.” Susan M., Farmingville, NY – 

Jeffery S., Holtsville, NY

“Dan and his men constructed a waterfall in our yard that exceeded all our expectations. The job was reasonably priced and completed just as it was designed. The crew was friendly and neat and obviously took pride in their work. When the job was finished in looked as if it belonged there. When a minor problem arose the following year it was taken care of promptly and efficiently. I have nothing but positive comments for Designscapes of Long Island and everyone I met during this project and would recommend them highly to anyone with no reservations !!” Jeffery S., Holtsville, NY

Lise R., Westhampton Beach, NY

“We were so satisfied with Dan and the entire Designscapes of Long Island crew that we didn’t hesitate to have him transform our front garden and walkway as well. I would not hesitate to recommend Designscapes of Long Island for any garden project….Dan is completely capable of overcoming any garden challenge with beautiful and creative ideas.”

-Lise R., Westhampton Beach, NY – 3/2019

“…Dan runs a very creative, professional, understanding, flexible, and most importantly an honest operation.  He presented a plan, a reasonably priced budget, and timetable and kept to all three. His workers were professional, detail oriented, and clean – They made sure we and our dogs could navigate the property on the weekends despite work being in progress. Over the summer when some of the plantings did not survive, Dan came in assessed the situation and made appropriate changes. He accommodated us on every level and our experience has been outstanding. We have and will continue to recommend Dan Steigerwald/Designscapes of Long Island and would be happy to speak to anyone who is thinking of using them for landscape design.” Paul S., Manhattan, NY

Regardless of how big or small each project was all were completed with the same degree of excellence and absolute commitment to my satisfaction (and far more difficult to my wife’s). Further, any issues arising post project completion have always been dealt with expeditiously, and with unwavering integrity – they simply stand behind everything they do.”  Brandon B., Woodbury, NY 

“…My husband & I worked very hard to find the right landscape company for our project. We went looking for the best & we found better. They offer honesty & quality at reasonable prices. Their staff is respectful & always pleasant. Every question was answered & every phone call was returned. I can’t tell you what a pleasure it was to work with Designscapes of Long Island.”  L. McKernan, Mt. Sinai, NY 

“My wife and I congratulate you and your crew on a job well done. Both terraces look great! We compliment you on your dedication and interest in the project. Particularly your personal involvement. We both got into more than we bargained for, but we are particularly grateful that at no time did you abandon your high personal standards of quality and excellence.”

– C. Mitchell & M. Donovan, New York, NY
