  • Do you love hosting people, but you don’t love your available space?

We know what it feels like to not love your outdoor living space. That is why we have been building dream decks in Delaware County for over 30 years.

Joanne A:  "Keystone Custom Decks is top notch! After meeting with Ron Yoder, there was no doubt that they could make our project come to life. Thank you Ron, for everything. We are so incredibly happy with our experience with this fine company and highly recommend them to everyone who is considering a backyard transformation. Their attention to every single detail and their superior workmanship is by far the very BEST! Our site manager, Steven, and his team of Jay and Willy were a pleasure to have here every day. They arrived at the same time every single morning and worked continuously all day, and cleaned up after each day. Thank you Steven, Jay and Willy for your outstanding workmanship and top notch professionalism! Thank you to everyone else behind the scenes at Keystone who helped to transform our backyard into more than we ever dreamed of!"

Hayler O:  "We had a pergola installed over a portion of our deck yesterday. The crew arrived right on time. They installed the pergola in a timely professional manner. It looks beautiful and really enhances the appearance of our home. And the price was significantly less than other estimates. The crew cleaned up afterwards. Nice group of men. If I need any deck work, this is the company I will call."

Ryan D:  "We put up a pavilion in the back yard and did a flagstone front walkway. Levi, Steve, Amos, and Eric were in and out in about 8 working days. The guys show up early and stay late. Left a very clean site every day, and worked with us on changes. All of the little details were taken care of and they did 100% of the job in a timely fashion....something that is unfortunately rare when hiring contractors. I would recommend to anyone and hire them again for any project."
