Swimming Pool Contractor & Builder in New Castle County, DE

“The process was fantastic from start to finish. Ron walked us through all of the design, offered great suggestions, and communication was thorough throughout. When Michael and his crew came to build, I could not have been more impressed. There was not a day they were at the house that my wife and I did not turn to each other and say how grateful we were that we hired Keystone. Michael and the entire crew had such an attention to detail and pride in their work. They took time to talk to my 2 year old son, and he could not have been more excited to see them all show up every morning. The piece that stood out most to us, was every opportunity they had to go above and beyond what I would have expected, they did. They did not just want to get the job done, they wanted perfection. Could not have been happier we made the call to go with Keystone, and Michael and his crew impressed day in and day out.”

“My wife and I recently had the pleasure of working with Keystone Custom Decks to transform our outdoor living space, and we couldn’t be more thrilled with the results. From start to finish, the entire Keystone team exceeded our expectations in every way. Ron’s professionalism and attention to detail set a positive tone from the outset. Sarah Schupp was instrumental in guiding us through various design options we hadn’t even considered. Her expertise and recommendations were spot on, making the decision-making process much easier for us. Permitting, often a lengthy process, was handled with exceptional efficiency by Paul Campbell. The construction phase, led by our project manager David Beiler and his outstanding crew, Chris and Ben, was nothing short of exemplary. This includes the masonry crew led by Will. Their craftsmanship, attention to detail, and commitment to quality were evident in every aspect of the build. They kept us informed daily and made sure all minor decisions were discussed with us to ensure our satisfaction. The end result is a beautiful, cohesive outdoor space that has already become the heart of our home. Throughout the month-long project, we not only admired the team’s professionalism and their friendliness and enthusiasm made the entire process enjoyable. It felt bittersweet to see them go once the project was completed. In summary, Keystone Custom Decks has earned five stars in people, process, and quality. Their expertise, perfect process execution, and a team that truly cares about their work have resulted in an outdoor living space we love. We highly recommend Keystone Custom Decks and look forward to working with them again in the future. Thank you, Keystone team, for making our dream a reality!”

“From start to finish, our family had a stellar experience with the entire Keystone team. This was a big project for us and we engaged with several groups before moving forward with Keystone. For us, we had the most confidence in their team to make our vision a reality. Our salea rep Ron listened to our requests and was patient through several design revisions and tweaks. DJ and his crew were incredible through the build process and day by day always communicated what was happening and what to expect. We couldn’t be happier with the final outcome and look forward to enjoying this space for years to come.”
