Lou and I can’t thank you enough for the wonderful job you did for us. The compliments keep pouring in and referrals keep pouring out! The landscaping job was beyond our wildest dreams.


- Sue and Lou Lucido

Having recently moved after 23 years at my old address, my only stipulation was that S.K. Complete move with me. For the last 20 years, they worked to create not only the most beautiful property on the block but also the easiest to sell. For expertise, professionalism and quality workmanship, they are unrivaled.


- Donna Nastro Huntington Bay, New York

Sean Kelly and his very talented crew helped us with a detailed plan and then executed what our vision was for our front yard landscaping as well as a stone front walkway and stoop. We loved and were so impressed by his work and impeccable skill that we had him come back when we were ready to rip out our old wood patio!


- Patti and Ed Carlson-Huntington, NY

We have already received so many compliments on your work, and it isn’t even the finished product yet. Our lawn, driveway, brick and stonework front and back, pool area and pool house are all beautiful thanks to you. And when you add all the additional shrubbery in the spring, we will truly have our dream house.


- Ilene and Mark Zelniker

From start to finish, S.K Complete Landscaping was a pleasure to work with. Very responsive and knowledgeable in all aspects of landscape design. Sean & his son answered my many questions, and during the job if there was anything I had a question about or a concern, it was listened to and addressed immediately. End result was high quality and the price was right on. I would definitely recommend S.K. Complete Landscaping and plan on hiring again for future projects!


- Mark G.

We would love to thank Sean and the entire crew for a phenomenal job. They installed porcelain tile walkway along the bulkhead on our property. The work was done with such accuracy. They also leveled the entire property and corrected several drainage issues by adding 100 yds of topsoil. All of our needs were addressed with quality, in a timely fashion and the guys were courteous, neat, and professional. Without a doubt, we will use them again for our next project.


- Anthony F.

The staff at SK Complete Landscaping are true artisans. They can transform your property into an oasis. We've been customers of theirs for over 25 years and through two homes and at least 7 major projects, they always come in on time and on budget. I would highly recommend Sean and the entire crew for all your landscape needs. From simple maintenance to the most complex masonry, they are simply the best.


- Robert W.

From conception to competition everything has gone absolutely perfect with every job they have ever done for me over the past 15 years. While living in Huntinton they did a Paver 2 car driveway, 2 walkways, cobble stone curb line in front of the house, entrance way into the house and a stone fireplace veneer with a blue stone hearth. I’m my Smithtown home they did a stone fireplace with a bluestone hearth. I have some big plans for work that I want done and I would look no further than SK.


- Edward C.

I just wanted to thank you for the amazing job you did on my backyard project. We are so pleased with the final product. Your team was meticulous and professional. It is clear you know the products that you use well and I appreciate the time and attention you gave us during the project. I have already recommended you to friends and neighbors!
