My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

I highly recommend this paving company. They stand behind their work and truly care about customer satisfaction. After the project was completed, a few stones needed attention, and they promptly came back and made the necessary repairs without hesitation. The owner, Giuseppe, personally ensured that everything was handled properly and met his high standards. His professionalism, integrity, and commitment to his customers are evident in the way he conducts business. The entire team was professional, reliable, and easy to work with throughout the process. It's clear why they have such a strong reputation in the community. It's refreshing to find a company that stands behind its work and follows through even after the job is complete. I would not hesitate to use them again or recommend them to others.

Review About 25 years ago we hired Gappsi to do our paver driveway and our patio. Giuseppe and his crew did a great job. They were professional and got the job done as planned with no issues. Giuseppe is always a phone call away if you need him for anything. Over the years as a paver moved or broke they were always here to fix or level or replace as needed. So when my wife and I decided to do a backyard makeover we knew who we were going to call. From the design work to the complete construction of the project, they were nothing but professional. We did a big project in our backyard, including a pool, outdoor kitchen pavilion and built-in fire pit. So whenever you have a big project like we did, there are always things that will come up, whether it’s a delay or a change that you wanna make as the project moves forward or something they will recommend as the project moves forward. Giuseppe and his entire crew were always available and dealt with anything that did come up in a very timely fashion. Things like this make all the difference in the world when you’re choosing a company for a big project. Having an owner that you can contact with a text or a phone call is amazing. He was always on top of anything that we had to address and it made for a smooth project. He did our job in our backyard over eight years ago. Everything still looks great and to this day, I still talk to Giuseppe. He’s only a phone call away if I need something done in the yard. Having a company that stands behind their jobs after all this time is a great piece of mind when you decide to hire a contractor.

Gappsi installed my brand new pool in 2020 6 years later it is beautiful with a beautiful stone patio and trim. Any time I had questions or minor issues Gappsi has supported all my pool/patio needs! They are committed to their product and customers with exceptional work!

Gappsi did amazing work by building a basketball court in my backyard. The job only took a few days and the court looks spectacular.

Gappsi is a stand up company. They installed synthetic turf for me over 10 years ago. I had a sprinkler line leak underneath unrelated to the work they did. Giuseppe Abbrancati the owner came to my house instructed me on what I should do. I fixed the leak and he promptly returned to level and reseal the seam for me at no charge. This was not a warranty issue. This is a great example of great customer service. They don't just stand behind their work but they stand behind their customers as well. Thank you Gappsi

Gappsi inc. completed a complete remodel of our kitchen and we couldn’t be happier with the results. Guisseppe Abbrancati and his team, Martin, Marion, and Marco collaborated with us to make our dream kitchen a reality. No matter what we asked of them , they were able to make it happen without hesitation. They were also by far, the most reasonably priced for the quality of the products that were used throughout the construction. There truly is nothing that this company can’t accomplish. I look forward to working with them again.

Giuseppe and his team did an oustanding job in recovering my pavers in the back yard. The previous contractor had done a very poor job and sealed the pavers without making sure that the surface was totally dry and the excess sand was brushed off. As a result, the sand showed under the sealer creating a spotty and chalky appearance. Gappsi and his team was able to chemically remove the sealer with specialized equipment and re-apply and reseal the pavers to bring out the original color. They worked diligently and completed the job on time and as promised. I strongly recommend Giuseppe for paver jobs.

Gappsi assisted me and my wife in designing a beautiful 5-Star Hotel looking Inground Pool to fit into our Nassau County backyard ... with space limitations. WOW! Job Well Done!! They really helped us get the most out of our yard. We still can't believe that we were able to fit a 16' by 20' Inground Pool plus a 7' Sun deck for water-chair lounging. They helped us design a beautiful 12' flowerbox feature (along 1-side of the Pool) with stone pedastals on either end to support our magnificent Pentair Lighted-Glass Water Bowls ... and in between them, a 4' Sheer Descent waterfall! They also saved us precious back yard space by installing all of our Pool Equipment in the back corner of our 2-car garage, adjacent to the Pool. We saw more than 7 Pool design companies before making our choice, but Gappsi was the ONLY company that exclusively uses natural stone in their work (instead of cement pavers)... and at a very reasonable price, by comparison. Our goal was to create the look and feel of a 5-star hotel resort, so we surrounded our modern spa-like pool with a creamy-white natural Marble Stone throughout the entire yard and added a crisp sparkling white accent stone around the flowerbox which houses the 4' waterfall & two 24" glass water bowls. They also rebuilt our 2 sets of outdoor steps, re-laid the cement floor in our 2-car garage, put in a dry-well for proper drainage and back-washing, laid beautiful natural blue limestone down our entire 60-foot driveway as well as in front our our 2-car Garage and BBQ area. Our driveway was edged with a beautiful large Belgian Block to give it all a crisp & pristine finished look. Finally, they surrounded 2 sides of our pool with beautiful 6' tall Arbourvides to complete the serine Spa-like atmosphere. This stunning Pool and backyard surround continie to blow our family & friends away, every time they visit! And, with the added LED Color Lighing in & around the Pool, House & Garage, and including the amazing outdoor sound-system we installed ... we truly feel like we are always on vacation at a luxurious 5-star vaction resort, and all within a few short steps from our home!! We are very thankful to the entire Gappsi team for their professionalism and their high-caliber work and attention to detail Kudos for a spectacular job, well done!! -Corey & Sandra Seaford, NY

We had GAPPSI design and install our entire outdoor space — patio, pergola, fireplace, and outdoor kitchen — and several years later, we’re still extremely happy with the decision. The quality of the original work was excellent, and the space has completely transformed how we use our home. What really stands out, though, is the level of service after the project was finished. Over the years, whenever a stone has cracked or needed attention, GAPPSI has come back and taken care of it without hassle. That kind of long-term support is rare and says a lot about how they stand behind their work. It’s not just a one-time project for them — they genuinely care about maintaining the quality of what they build. Highly recommend GAPPSI if you’re looking for a company that delivers both great craftsmanship and reliable ongoing service.

Giuseppe the owner is a great guy. He came to my house several times to help me with some of my concerns and he didn't charge me to just come and do estimate. His pricing is very reasonable and more importantly he is caring guy. I would highly recommend Gappsi Stone !!

Gappsi Pools was fabulous. My project was extremely difficult and it was handled with care and tremendous foresight. Giuseppe the owner, was very involved and his suggestions were spot on. The end result was better than expected and is suitable for publication in home and garden magazines. All visitors who see the pool and masonry work love it . The best part was that the project was finished on time and the surrounding backyard was left in a pristine condition. I am an extremely discerning and demanding customer and I had no complaints at all. I highly recommend Gappsi for all pool , masonry,landscape design projects . Outstanding owner who runs an amazing company. Steve & Mary Ann DiPalo
