    Be Proud
    of Your Space

     Become the envy of the neighborhood with your beautiful outdoor space.

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 love our new deck!  After 18 years of living in our house with an awful brick patio, we decided to get a deck.  From the first meeting with sales, Keystone was timely and professional, and a great company to work with.
The project was begun even earlier than our planned schedule.  We are awaiting warm weather to enjoy our new deck!"
