"Very impressed with this outfit from start to finish. Everyone I interacted with was pleasant; the receptionist, the sales team, the permitting manager, and the construction crew themselves. The work was done in extremely short order, and professionally at that. This business is a well oiled machine, a rare find in the construction industry. No complaints.”

- Matthew

"The Keystone builders came out and did what they do best: they built us a wonderfully looking deck, one that we enjoy so much, even in the cold days. Also, most neighbors around the area stop by to ask us who built it, and we confidently say it was Keystone. Thank you so much.”

I shopped around at a lot of deck companies and was blown away by Keystone’s customer service and attention to detail. They had top-of-the-line designs that allowed us to visualize our dream outdoor living space. Their new showroom was amazing and I am excited for the cafe. Mike Fisher was great to work with. He was friendly, easy to work with and had a good eye for design. Mike was also flexible and down to earth. The owner Ron was also very hospitable and great to do business with. support this local business! They do great work!

- Timothy

Highly recommend Keystone! From the contract signature to the design process to even dealing with township red tape. They were with us through it all. The onsite team was so friendly, professional, always on time, and cleaned up after themselves daily. The end product - gorgeous. The deck we dreamed of. Could not be happier.

- Kristen

Keystone custom decks are professionals from start to finish. Video rendition was great and woman in the office were pleasant and knowledgeable. Dave King and his crew were top notch craftsman and true gentlemen to work with! Starting from the demolition of the deck to the carpentry and masonry work and everything in between was excellent! Would highly recommend!
