"Mahlon and crew did a fantastic job with our deck. They were spot on with the design, flawless craftmanship and communication all along the way. Al of my neighbors have asked about our deck and how incredible it looks. I would highly recommend Keystone to anyone who wants a fabulous deck with amazing customer service."

- Nate Scozzaro

"Elmer and his crew did a magnificent job. Nothing was too much for them to handle. We have had contractors before that always had a reason why something couldn't be done. This was not the case. Will definitely hire for future work."

- Tom Petrucci

"Keystone Custom Decks was a pleasure to work with from start to finish. The planning stage was easy. Mahlon is very knowledgeable and provided us with recommendations to make the deck more ascetically pleasing as well as CAD models to finalize design options. The team who built the deck was highly skilled, which is clear in the final result. Also, the build team was patient and considerate of our family. Plus, the price we paid was a great value. My family and I couldn't be happier with the result. We highly recommend Keystone to anyone looking to build a deck & increase the value of their home."
