The deck is gorgeous and we couldn't be happier with our choice of Keystone Custom Decks."
We make the process as easy as possible

Pat: 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 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 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 are 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!
