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 Glen Mills and nearby areas for over 30 years.

“Keystone Custom Decks recently completed our deck project which included a covered porch. From start to finish everyone we worked with and the process itself were top notch.

Ron did a great job talking us through all of our options to come up with our final design. The crew of Daniel and the guys were extremely professional and a real pleasure to work with. They were extremely communicative all along the way, worked through really tough weather, kept a clean worksite, and just had a great work ethic.

The finished product is beautiful and we couldn't be happier. We strongly recommend Keystone Custom Decks.”

-Mike C.

“We recently had Keystone Custom Decks design and complete an outdoor living area project to include a custom roof over our patio, along with a pergola to include a retractable top canvas and side curtain. Their creativity and knowledge provided us with a top-notch solution to create shade on our patio since we get the afternoon sun. The entire process from beginning to end was handled professionally and completed with outstanding quality.”

-Suzanne
