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 dream decks in the Mechanicsburg area for over 30 years.

“We went through a long and extensive process of reviewing companies and contractors for our deck and patio.  Through it all, Keystone was fantastic.  Their quote was fair, and they worked with us on a few last-minute changes.  It's a pleasure working with a company that can actually deliver a project on time and on budget.”

- Paul W.
