"We worked with Keystone to build a new deck. Even at this difficult time related to Covid they did an outstanding job! The Team was very professional. The communication was great; we discussed all details before the project has been started. Guys showed up before the usual start time and began early."

- Irina Kolos

"Excellent job on our new deck. We are very pleased with the work and our work crew was willing to make changes as needed."

- Ted

"We just wrapped up our patio project with Keystone and could not be happier with the results and process. All around Keystone has a great team. The quality of the materials Keystone offers is top-notch as well. In my opinion, where Keystone truly separates itself is with its people."

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!"
