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 Berwyn and nearby areas for over 30 years.

“We can't say enough great things about our experience with Keystone Decks. From the initial meeting to the final cleanup, they were amazing to work with and we can't be happier with our deck project.

During the proposal phase the team provides detailed images so you can see EXACTLY what the finished project will look like. The crew led by Matt was professional, friendly, hard-working and provided great communication the whole time.

We are thrilled with our new deck and pavilion! And we are happy to be a reference for anyone who has questions.”

“Their work is superb. The crew is polite, professional, on time, and EXTREMELY good at what they do. You get a quality product and the price is so reasonable. I could not be more happy with how easy it was for them to install our new deck..”

-Becky K

“All Keystone’s employees and subcontractors did a great job building the deck. The landscapers prepared the site and landscaped after the deck was complete. The concrete crew and stonemasons were excellent. The building crew, led by Reuben, was superb. Many of our friends are in construction and they all commented on the quality of work and materials.”

- Paul H.

"Upon embarking on a major home renovation, my concern always was - there are so many contractors out there, am I picking the right partner? Well, emphatically, at every stage I can say Keystone was the right choice and I would choose Keystone every time, if I had to do it again.”

- Kevin A.

"We recently got a new deck installed and I cannot say enough great things about the experience we had with Keystone Custom Decks. The decision to go with Keystone started with the ability to go to their showroom and see the actual materials. It was also a great touch that they were able to do a digital rendering of our design.”

- Anthony A.

"Overall incredible experience. From the start to the end, everything exceeded my expectations. Working with the primary point person (Dan) was incredible. He graciously listened and provided feedback on all our crazy change requests! Would highly recommend these folks to anyone.”
