“We couldn’t be happier with our decision to work with Keystone on our deck replacement. From the initial sales visit with Joey, through to the build by Ivan and his team, every step was well organized and professional. Keystone put together the most cohesive design and their experience really shined throughout the entire process. Couldn’t recommend them more!”

“The Portico Jonathan and his crew built was exactly how we had imagined it to be. The masonry crew lead by Alvin Lapp did a wonderful job. We had always wanted a Flagstone walkway and they made it happen. Much respect to the crew for working during the recent heatwave. We are very happy with how everything turned out. All and all we had a great experience with Keystone Custom Decks and would highly recommend them.”

“Keystone installed new railing and composite decking at our home recently.  The crew did a great job, and the process was incredibly smooth.  Mahlon and his team were excellent and I’d highly recommend them.”

“From our initial meeting with Joe in May, we were very pleased we chose Keystone.  In just over one week, goodbye 26-year-old, worn, and unsightly wood deck.  Hello, TimberTech lovely outdoor living area and shower.  Thank you all at Keystone.”
