"Great experience from start to finish. Our project turned out even better than we thought.”

- Dan

"John Earvin and his crew gave us a beautiful, custom deck that exceeded our expectations. John and his crew were professional, prompt and incredibly gifted at their craft. We truly have the custom deck that has the envy of the neighborhood. I highly recommend them to anyone who is looking for their own dream deck. I can't thank you enough for holding my hand through initial proposal to final inspection. They even sent my daughter a beautiful bouquet of flowers for her 6th birthday. We are so grateful to Keystone, John Earvin and his crew for making our dream deck become reality!!”

We couldn’t be more delighted with our new deck, fence and pergola. Dan, our project manager, along with his team, Dave & Josh, worked diligently to complete our beautiful addition. Their care, professionalism, and kindness was appreciated by us as well as our neighbors, who marveled at the team’s work ethic. The slope of our property required great precision and agility in design. Their excellent craftsmanship is the showpiece of our home. I would highly recommend Keystone Custom Decks.
