SO EXCITING! I purchased Gappsi's Travertine natural stone, and they came through like champs. I'm a returning customer, and Greg, & (of course) Giuseppe helped make the buying decision very easy. The delivery went seamlessly in a challenging entry situation. The driver, Antonio couldn't have been more helpful, and professional. Most of their employees have been there for 10 plus years, because there are very few that can match this amazing operation. Thank you for rescuing my backyard!

Gappsi has me now living in Nirvana!!! My backyard was a new builders mess, a nightmare and had a significant slope downward. They installed a beautiful multi level resort in my backyard. The built in gunite pool has a spill over spa and an auto-cover that keeps it warm, clean and well protected from things and little ones from falling in. Its a great safety feature. I can keep it closed and not worries at all. It opens in 30 seconds. The Travertine patio is large and expansive. The lower tier has a water feature and fire pit that and a nice touch at evening. Giuseppe and his entire team have always been professional and respectful. He has always answered the call to come back without hesitation to fix anything and everything. 4 years later, the backyard has filled in and is now a showstopper!!! I highly recommenced the Gappsi team!

Gappsi's Fiorito 4" veneer stone

The quality and variety of their stone is impeccable! It's like nothing we could find locally. There was a bit of a hiccup coordinating getting the materials shipped to us in VA (which was out of Gappsi's control), but outside of that, the process and experience was seamless.

Let me start by saying this is by far the best home improvement experience I've had!! I wanted to…read moreredo my entire backyard and driveway since I've been working from home due to COVID and spend so much time in my yard now. I had a few other companies come and give estimates but they were lacking in the design area. Devin and his team really impressed me with their professionalism, creativity, and respect for my property. I did not have to chase them as to when they would be showing up as I have with other contractors. His estimate was very detailed and was easy to understand with breakdown and description. His 3D rendering was extremely impressive and really was representative of what he was able to create. Dan was present every single day to get the men set up and to do a check-in with me to make sure I was happy with the process from start to finish. Each day the crew left my property neat, never leaving garbage behind, and were very mindful to never leave my gates open due to me having 2 dogs. As for the work... I was unsure what I wanted exactly but knew I didn't want a cookie cutter yard like most of Long Island. Dan and Devin both worked with me to pick out the perfect colors and showed me how to best utilize the space I have. With landscaping, they were able to give me more privacy and brighten up my entire yard with beautiful perennials. The hot tub area they created with an outdoor television and pergola will definitely be used all year round. The outdoor BBQ and bar area will be the highlight of my outdoor parties! My favorite touch though was the beautiful pool and surrounding stone with an automatic pool cover which means I don't have to worry about my pups accidentally falling in when I'm not outside with them. I really can't speak highly enough of Devin and Dan's work, talent, and professionalism.

Our street has become increasingly busy making it difficult to back up during rush hour. We thought…read morea circular driveway would be a good solution and interviewed a few masonry firms - who either said it wasn't doable in our small space or disappeared altogether. Based on Yelp reviews we then called Devin from Flawless Masonry & Landscape who told us a circular driveway was absolutely doable! We were so impressed with Devin's design skills (including clear scaled digitized plans) and experience that we hired him on the spot. Plus Flawless's pricing was lower than other quotes we got. Icing on the cake. Then the pandemic hit so the job was delayed (NY orders), but Flawless came through after re-opening and did a superb job for us. The new driveway is both beautiful and functional, even our crabby neighbors like it! It was a big job but Flawless's skilled and friendly crew managed to finish in a week. Tiffany from the office was super responsive and polite throughout the project, keeping me in the loop at all times. Thank you Flawless for your integrity, talent and hard work!
