“Keystone Custom Deck was the greatest.  I got 4 estimates and went with Keystone.  Truly a professional group, and friendly, and easy to work with.

They gave us 3D images of the design on our house, and the finished product looks just like the design.  They walked us through everything and were attentive every step of the way."

-John Walston

"What can I say... QUALITY & SERVICE!!! This is the second deck we've had built with Mahlon and Keystone Custom Decks, and we're even happier this time around. To see what they've grown into is Amazing, but not so surprising. When you love what you do, and you genuinely like to take care of people, being successful is a by-product! The experience is wonderful! Mahlon "makes it easy", he really hears you in the consultation, what you like, what you want, and what you need... he always hits the goal of making you happy and meeting the budget. Then he goes back and communicates exactly that to the crew! Then come Anthony and the guys! WOW! They are AMAZING! The "on the job" communication and teamwork is superb. From the moment they arrive each day until they leave, their focus and goal is to "deliver the promise" that Maholn makes when you first sign. There's no crazy stuff either, no cursing, no cigarette butts to pick up, my wife even said she definitely felt safe and comfortable with the guys working here (we've had other experiences). Just all in all, this is a great company that does great quality work! God Bless Keystone Custom Decks!"

- Pat Kalaboke

"Absolutely amazing experience with Keystone Custom Decks. Truly hard-working individuals with Nate and his team. Full covered deck, A-frame, beautiful finishes and could not be happier with the result. Look forward to using it for many years to come. Highly recommend using Mahlon/Nate and their teams."

- Drew Beganny

"I have nothing but positive things to say about Keystone Custom Decks! Mahlon was amazing to work with and so helpful with the design. Our deck was built in early March (5 months ago) and we have yet to find anything we would have liked to be done differently. It is perfect! The crew was professional, on time, clean and quick!! Other than the sounds of work being done, I wouldn't have even known they were there. It was such a wonderful experience from start to finish! I have recommended them to anyone that mentions needing a deck or a patio. I will definitely be calling them again for our next project! THANK YOU Keystone Custom Decks!!!"
