Working with Keystone Custome Decks was a delightful experience!  From the initial quote, to working with us on budget and amending the design several times, it was a better experience than we could have hoped for!
That's not even mentioning the amazing professionalism and efficiency of the crew, and best of all - our beautiful deck!  It is everything we could have hoped for and more!

Helen K - "Our deck came out as planned, it is beautiful. The Keystone team was very professional, polite, and accommodating. The employees were friendly and respected our interest to socially distance while still keeping us informed of the progress and options. The workmanship was only eclipsed by their work ethic. I would highly recommend Keystone."

Terese G - "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!"

Kate K - "We cannot say enough good things about our experience with Mahlon and his team. From design to installation, everything was perfect. The crew was extremely professional and efficient. The workmanship and materials are superior and our deck came out beautiful. We would highly recommend Keystone Custom Decks."

Mark V - "We’ve completed many upgrades to our house in the last three years and Keystone Custom Decks was by far the best contractor we worked with. Mahlon did an excellent job of helping us design the perfect deck. He made design suggestions, provided multiple pricing options, and supplied a full-color rendition of the proposed deck, using our actual house, with his quote. In terms of pricing, their price was competitive and included more features than the other contractors who supplied estimates. The finished product matched the supplied full-color rendition exactly. The crew cleaned up every day and on the final day left the area in better condition than when they started the job. They were the best work crew we have had work on our house."
