"We have been so impressed with Keystone Decks: the company, the crew and the workmanship. The design process was a breeze, thanks to Mahlon, and I cannot say enough how much we appreciate the quality of work that they did. Anthony was incredibly professional and kept us updated on their progress. We were particularly impressed with how they handled the flashing issues that arose, and we both felt that they built this deck as if it was their own. They cleaned up the site every day and it was immaculate when the project was completed. We cannot believe the two of them built this deck in 3 days. We also appreciated the prompt communication from Mahlon. Any time we had a question, or a design change. he responded immediately. The work began about a week earlier than estimated, and was completed a day or two quicker than estimated. Thanks again and we will certainly recommend your company to relatives, friends and neighbors as their needs arise."

- Dawn Emery

"Working with Keystone Custom Decks was a delightful experience! From the initial quote, to working with us on our budget and amending the design several times as we made new considerations about our requirements 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 new deck!! It is everything we could have hoped for and more! It was a headache free experience from start to finish! Their portfolio is extremely impressive and we have no reservations about recommending them to friends and family!! If you are looking for an outdoor living space, THESE ARE THE PEOPLE TO TALK TO!!"
