“What a great experience with this contractor. After building my some with many different contractors I can safely say that Keystone is a cut above the rest.
They handled all the bumps and dips that come with a larger project in stride and made our outdoor space amazing. The attention to finishing detail was greatly appreciated!"

John Brisbois: "Keystone Custom Decks is the best contractor we have ever dealt with. From initial contact with Mahlon to project finish and cleanup, they were responsive and professional.
It’s amazing how fast they completed our deck project along with the excellent workmanship. Kevin and the crew showed up early in the morning and all members stayed busy all day. Whenever a decision needed to be made in construction, they kept us in the loop.
We will be recommending them to others and will contact them if we need something else that they can do."
Len Swain: "The crews that worked at our house were all great guys, talented, skilled, friendly and very willing to make sure the final product was something special. Everyone that sees our deck/ patio have made very favorable comments on the high quality of workmanship. Thank you Keystone for the outcome that we envisioned.
Terese Genecco: "We love our new deck! The entire experience was relaxed and professional from the initial quote process with Mahlon through to the final product with Anthony and his crew of very hard workers. The gift of wine and two etched wine glasses was a lovely finishing touch! We highly recommend Keystone Custom Decks. They are replacing my father's deck next and he can hardly wait after seeing the quality of ours!"
