“We recently hired Mahlon and his crew at Keystone to re-do two decks.  All the pricing was laid out, our options were clear, and the terms were perfectly legible.  Mahlon was patient with us throughout the entire project and communicated thoroughly throughout the process. Nate and his crew showed up when expected.  They were extremely professional.  They maintain a serious job site.  Every night all tools and equipment were packed up and put away. If you’re considering redoing your deck, call these guys up.  I am so excited to enjoy our new decks this spring and summer!”
