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 Avondale for over 30 years.

“Where to start - right from the beginning we knew Keystone was the way to go.  Ron did a great job recommending the best possible options for our project, and it came out better than expected.
The crew was absolutely amazing to work with and their work ethic was spotless.  They were very knowledgeable.
Overall I would give Keystone 10 stars instead of 5.  Keystone exceeded our expectations in every aspect of the project.
-Vinod Murali
