Our family recently relocated to East Islip. Our backyard was in complete disarray and need of a complete renovation. We contacted Dingman pools, and The owner William Dingman gave us a full assessment of what needed to be done. He was professional, informative, and honest. He gave us a date and a fair price and explained thoroughly what needed to be changed and what we could salvage. His team of experts transformed our backyard from bare ruins to a resort. They installed a new liner, replaced all the pavers around the pool, and added a beautiful walkway and a complete sitting area with a fire pit and lighted pillars. They also built a beautiful waterfall that changes the color of the water by lighting. They installed a new energy-saving heater and heated the pool to a perfect desired temperature. The pool was chlorine filtered; William suggested a salt cell conversion, so we went that route and couldn’t be happier with the clarity and cleanliness of the water. Everything William promised came to fruition. No hidden cost, no surprises. It was a pleasure working with William and his team. The clean, respectful work crew showed up every day on time, and we’re all perfectionists. We also use their pool service; the staff kept our pool spotless all summer long and always showed up. Thank you, Dingman pools, for giving us the backyard of our dreams.We are looking forward to our next project refurbishing the front of our house.
