“Keystone custom decks was an A+ experience from start to finish. From the initial consultation to the last day of construction, I couldn’t be more pleased with the communication and follow through. Every question I had along the way was answered in a timely manner and to my satisfaction.”

“Fantastic experience from start to finish. Ron made it easy from the start, and the crew (Willy, and his team) was great to work with, communicated well, and even pushed through freezing temperatures to get the job done. The final result is a beautiful deck that completely transformed our outdoor space. Couldn’t be happier and will absolutely recommend them!”

 “When you choose Keystone Custom Decks, you choose excellence. We chose Keystone to complete our dream outdoor living space after visiting their beautiful showroom and learning about their company values and work ethic. Working with Joe and then the design team was seamless. It was thrilling to see our ideas in a 3D rendering and walk-through. After that, we were sold! The best part of the project was seeing the vision come to life. For us, we had the pleasure to work with the best crew at Keystone. Our foreman, John, and his team Aaron and Mike were extraordinary and skilled. They were so professional and didn’t mind us lurking, asking questions and taking pictures of their exceptional craftsmanship. The crew arrived on time each morning and worked diligently all day. John was in constant contact with us if any changes were needed. We thoroughly enjoyed having this crew here each day and getting to know them. They became like family. I can’t forget about our mason team, Nate and Ray. They worked with us to make a few changes to grout color and patio stone without hesitation. Their masonry work is beautiful and adds such detail to our finished product. We can’t say enough about everyone that we have encountered at Keystone Custom Decks. Our finished outdoor oasis far exceeds our expectations. We have recommended Keystone to neighbors and friends and will definitely hire them again for any additional projects.”
