‘We recently used Keystone Custom Decks for an outdoor living space. From the very first call to the final walk thru, the Keystone team could not have been more pleasant and professional. Just awesome to work with. The design, materials, and workmanship was all top notch. We are so happy with how everything turned out and can’t recommend Keystone enough!!”

“Overall, our experience with Keystone Custom Decks was excellent from start to finish. The quoting process was smooth and straightforward, and visiting their showroom was incredibly helpful for visualizing design options. The team offered thoughtful enhancements—such as a bar rail that truly elevated the look of the deck—without ever pushing unnecessary upgrades.”

“The finished project is incredible, and more than we could have imagined. The roofed deck has become a primary living space of our home, and we use it any chance we can. Our new patio has completely transformed the backyard, and we have already gotten tons of compliments from friends and family. Keystone’s team, led by Sammy, guided us through every step of the process, offered helpful suggestions, and kept communication clear and consistent.”

“John Earvin and his crew gave us a beautiful, custom deck that exceeded our expectations. John and his crew were professional, prompt and incredibly gifted at their craft. We truly have the custom deck that has the envy of the neighborhood. I highly recommend them to anyone who is looking for their own dream deck. I can’t thank you enough for holding my hand through initial proposal to final inspection. They even sent my daughter a beautiful bouquet of flowers for her 6th birthday. We are so grateful to Keystone, John Earvin and his crew for making our dream deck become reality!!”
