    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 dream decks in Adams County and nearby areas for over 30 years.

“Keystone did a great job explaining the process and pointing out the differences in construction between the companies we were considering.

The workmanship was excellent and we were very happy with the results. Anyone we talked to in the company was a pleasure to deal with. Highly recommended.

“Mahlon and his team did an excellent job with our small deck project. He helped get my thoughts down on paper and in the end the deck turn out even better than we had imagined. It was completed in no time and we have already been able to enjoy the sunshine!

- Kristen M.

“All the neighbors agree on what a wonderful job and how much it changed our home. You are a stand behind your work company after having some issues you came right out to solve the problem. Your honesty and integrity are outstanding. I would and will highly recommend your company.

- Amy H.

"We just wanted to let you know how pleased we are with the work that Keystone Custom Decks did in transforming our outdoor patio. From the initial consultation with Ron Yoder to the final build, the entire process went smoothly. Matt Blank and his crew were the best!

- Dave K.

"Not only did Mahlon help us design exactly what we wanted (with super-helpful 3D renderings), he created exactly what we wanted. He and his 2 teammates were here bright and early and worked SO FAST. They were kind and respectful, which was especially important given that I'm home with my young kids who love to watch and ask questions.

- Andrea R.

"We had a difficult site with steep slopes and Mahlon and his crew did an amazing job of minimizing the disturbance and working with the grade. The decks (two separate decks) are beautiful and just when I was sure they were done with an area, they added more trim, more detailed finishing work. The final product is just so wonderful!

- Brenda E.
