“In addition to being great workers, they were really great guys. We enjoyed having them around. They were truly vested in making sure we were happy with the results. Sammy even helped us with temporary fencing to keep our 3 large exuberant dogs out of the way and safe. We have to give a shout out to A.J. and Preston, who were only here for one day. At Sammy’s urging, they were able to transplant our much loved Magnolia bush! The Magnolia survived, and so did the baby birds!

We have no hesitation in recommending Keystone Custom Decks to anyone looking for a great company to work with!”

“Keystone installed new railings 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.”

“Each morning Josh informed us what had occurred the day before and what would happen that day. Thank you, Josh, for the recommendation of wider steps. Good call. John and Paul did a great job building our deck and outdoor shower, from new concrete footers on up. Great craftsmanship. John even returned on a Saturday to finish clean up and power washing. ”
