"Incredible skilled and detailed workmanship! Mahlon and his crew did an amazing job minimizing disturbance on our difficult, steep back yard. The deck is gorgeous and we couldn't be happier with our choice of Keystone Custom Decks."

- Bren Bunny

"We recently hired Mahlon and his crew at Keystone Decks to re-do two decks. When we first met Mahlon, we were impressed with all of the various choices and implications of different materials. He was neither pushy nor condescending. Mahlon provided us with amazing visual renderings to help us picture what the new decks would look like along with his quote. They were extremely professional with the little hiccups that inevitably occur on big jobs. They shared any concerns with me and handled them correctly. They maintain a serious job site. Every night all tools and equipment were packed up and put away with care for their gear. Never was garbage left around to blow around or trip over. It’s all these little things I point out to show how much these guys seem to care about the job that they do. It all builds up to their serious level of craftsmanship. The result of all of this was 2 absolutely outstanding decks that have transformed our living spaces."

- Brian Schneemann

"Keystone Custom Deck is a superb company. From the quality of their work, to an extreme knowledge of decks, politeness and extremely pleasurable workforce, they have transformed our deck to an outside paradise. These guys are LEGIT. I would recommend this company to whomever is looking to build a new deck, upgrade their current one or just need a stellar outdoor place. Keep up the good work Keystone Custom Deck and thank you for your workmanship. Our deck looks beautiful."

- Dejan Jozic
