  • Do you love hosting people, but you don’t love your available space?

We know what it feels like to not love your outdoor living space. That is why we have been building dream decks in Chester Springs and nearby areas for over 30 years.

“Keystone Custom Decks was fantastic. From the initial meeting with Ron, to the walkthrough in their gorgeous new showroom you really got to see your dream deck come to life.

Their 3D imaging was incredibly helpful envisioning the finished product. The communication along the way from start to finish was just the best. You knew exactly what was happening and when.

Then when Danny and his crew arrived, they got right to work despite the wet, sometimes soaking, weather. Every night the job site was cleaned up and at the end of the project, they thoroughly cleaned everything. We would highly recommend Keystone to all. Thanks, guys!

“After selecting Keystone to build our outdoor living space - they continued to go above and beyond to make sure we were happy, informed, and part of the process. Elvin and his crew were amazing, efficient, courteous...and maybe the most important - the end product is just awesome. We are incredibly pleased with the outcome and excited to have this new outdoor living space to relax and spend time with the family!

-Garret P.

“The team who built the deck was highly skilled, which is clear in the final result. Also, the build team was patient and considerate of our family. Plus, the price we paid was a great value. My family and I couldn't be happier with the result. We highly recommend Keystone to anyone looking to build a deck & increase the value of their home.

- Erica L.

"We were particularly impressed with how they handled the flashing issues that arose, and we both felt that they built this deck as if it was their own. They cleaned up the site every day and it was immaculate when the project was completed. We cannot believe the two of them built this deck in 3 days.

- Dawn E.

"The entire team at Keystone was very professional from the initial design and consultation phase to the final completion of the project. Randall's 3D renders really helped us to envision what the final project would look like, and helped to guide us in making adjustments and changes to improve the functionality of the living space. My family and I will surely be enjoying our deck and patio for years to come.

- Lawrence H.

"Keystone Custom Deck is a superb company. From the quality of their work, to an extreme knowledge of decks, politeness, and extremely pleasurable workforce, they have transformed our deck to an outside paradise. These guys are LEGIT.

- Dejan J.
