Kelly C - "We can't say enough great things about our experience with Keystone Decks. From the initial meeting to the final cleanup, they were amazing to work with and we can't be happier with our deck project. During the proposal phase, the team provides detailed images so you can see EXACTLY what the finished project will look like. The crew led by Matt was professional, friendly, hard-working and provided great communication the whole time. Keystone will not be the lowest estimate you receive, but we can attest that the quality is beyond the price and worth every penny. We are thrilled with our new deck and pavilion! And we are happy to be a reference for anyone who has questions."

Mike F - "My wife and I very highly recommend Keystone. From design at their showroom, options selection and professional advice to the final sign off they could not have been more quality/service conscious. Their on site team was courteous, efficient and on schedule. Quality unsurpassed in my view. They are the best!"

Anthony S - "We recently got a new deck installed and I cannot say enough great things about the experience we had with Keystone Custom Decks. The decision to go with Keystone started with the ability to go to their showroom and see the actual materials. It was also a great touch that they were able to do a digital rendering of our design. Once we got the quote and timeline we did not believe they could stick to such a short window to do all the work, but they did exactly what they said they would. The experience only got better once the team started to work. Johnny and his crew were absolutely amazing. They have a great work ethic, pay attention to detail and the communication was fantastic (any item that came up they would explain to me and provide a suggestion, as well as kept me in the loop of when they would be there, what they would be working on, etc). Their professionalism was off the charts, my wife and two impressionable sons were at home most of the time when they were working and we felt comfortable with the team. Overall we had a first-class experience and I would recommend Keystone for anyone that is looking for a new deck."
