“We had Keystone recently complete our patio and we love the results!  It was great working Mahlon and the crew.  Mahlon answered several of our questions during the initial planning of this project and throughout as questions came up.
The team was professional, organized, and completed the project in a timely manner.  They were in frequent communication with us, and they were flexible with last-minute changes we requested.  Very skilled at what they do!"

Brian Felber - "We couldn't be happier with our new covered patio!!! Keystone Custom Decks did an amazing job creating a beautiful outdoor living space utilizing our existing patio! The new roof structure is seamless, it looks like it was built with the original house construction and is everything I envisioned. The 3D rendering was spot on, communication, professionalism, cleanliness, attention to detail...overall a great experience working with Mahlon, Nate and their team...they are truly hard working and seriously skilled craftsmen!!
Thank you, Keystone."

Jackie T - "We had an excellent experience that started with Mahlon who designed a beautiful plan for our new deck and carried all the way through the project from start to finish.  The 3-man crew led by Nate was professional, friendly, and very hard working.  They came early every day, worked hard even when the weather was snowing outside, and cleaned up each night before they left.  Our deck looks beautiful, and we can't wait to enjoy it this summer.  I would highly recommend Keystone for anyone looking to replace or build a deck.  My highest recommendation."

Becky K - "Keystone Custom Decks recently built us a beautiful new deck. The process was so easy. Our options for materials were clearly laid out and the price was reasonable. The crews were polite, professional and SO QUICK. Our deck was done in 2 days! I would highly recommend them for anyone looking! We are thrilled with the result and have been enjoying so much more outdoor time as a family now. Thank you Keystone!!!"
