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 Harford County for over 30 years.

“Words can't describe how happy we are with our deck.  After working with several contractors over the last year, Keystone was by far the best experience we have had making improvements to our home.
Communication was excellent throughout and they were even able to finish our job almost a month earlier than expected.
As an added bonus, every person I spoke to in the company was professional, kind, and respectful!  I can't recommend this company enough!"
-Andrew S.

“We met the Keystone team at an outdoor convention and talking to them made us feel confident and comfortable to work with them on our Trex deck.  Anthony was our onsite manager and the team worked really hard to get our deck done in the timeline as promised. The team was super professional stayed super focused on the job.”

- Kristen Stanton

“Truly an outstanding experience start to finish with an exceptional outcome. From the beginning, Ron Yoder helped us envision our dream deck and move it to reality. The crew, led by Steven, Marlin, and Johnny, were absolute professionals from start to finish; were responsive to our questions during construction; and are clearly masters of their craft. Highly recommend if you are in the market for a new deck/outdoor living structure.”

- Drew B.

"We absolutely LOVE our new deck from Keystone! Our crew - Michael, Marlin, and Ivan - were friendly, hard-working (even in a heatwave), and maintained good communication with us throughout the process. They even welcomed the non-stop questions from my 3-year-old about what they were doing, without skipping a beat ... very much appreciated!”

- A. Clarke

"Top notch service from the initial conversation with Ron, through all of our township code challenges managed confidently by Dave, and to the final product executed expertly by Daniel, Dave, and Dave. Highly Recommended.”

- Mike Puchtler

"These guys did what they promised, on time, and then some. The best contractor we have ever worked with. I would recommend them to anyone. Incredible attention to detail. Positive work ethic and commitment. Daniel's team was amazing.”
