At Keystone Custom Decks, we believe having your dream outdoor living space designed and built should be an enjoyable and painless process.

  • Do you love hosting people, but you don’t love your available space?

  • Do you enjoy spending time outdoors, but your existing outdoor space is unattractive or unusable?

  • Do you have a vision for your dream outdoor living space, but you feel overwhelmed by the construction process?

We know what it feels like to not love your outdoor living space. That is why we have been building custom decks for over 30 years.

“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!"
