"We just wrapped up our patio project with Keystone and could not be happier with the results and process.

All around Keystone has a great team. The quality of the materials Keystone offers is top-notch as well. In my opinion, where Keystone truly separates itself is with its people."

“We are absolutely thrilled with the front and back decks that Keystone built for us! From the design process with Mahlon to the crews who worked tirelessly each day to complete the process, Keystone is definitely a professional and skilled contractor.
They answered any question or concern we had as the project progressed and the finished product is just beautiful! I would recommend Keystone above all others without hesitation."

"We are so impressed with the quality and workmanship by Keystone Custom Decks on our new covered deck/patio. The crew on site was excellent and we could not be happier with the results. The whole company is very professional, they left the work area clean at the end of each day and put up with all of my questions regarding the build to ensure we received exactly what we were expecting. I have to thank Mahlon for accepting the project even though it is much further away than typically used to. Thank you again to the great crew for the long days and sacrifices away from wife and family. Can't say enough great things about Keystone."

- MJ Meyer

"Keystone Custom Decks was the most reliable contractor we’ve ever had the pleasure of working with. To say they were impressive would be an understatement. From start to finish they were incredibly professional; the communication was excellent, and we never experienced a single negative issue or concern. We had multiple changes to the scope of the project along the way, and they were very patient and accommodating with each one. The overall level of customer service and professionalism far exceeded our expectations."

- Jay Brie

"We couldn't be happier with our decision to use Keystone Custom Decks to replace our old deck. Every step in the process, design-quotation-construction, was done professionally and in a timely fashion. We would especially like to highlight that the crew was outstanding! They kept us informed throughout the week-long project, met every commitment they made, and went above and beyond to ensure that the end result more than met our expectations. We highly recommend Keystone Custom Decks!!"
