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 Kennett Square and nearby areas for over 30 years.

“We recently hired Keystone Custom Decks to replace our existing wood deck with a new composite deck and roof. 

Everything about their business is "Class A"; from their sales rep, Ron, to Bradley who runs their "world-class" showroom, to Matt, Jonathon, and Merv who were the most professional crew we have ever worked with.

They completed the entire project in less than two weeks, they cleaned up every day, and they showed up at 6:59 am when they said they would be there at 7:00 am. Their workmanship was impeccable. We truly miss not having them at our house. It's no wonder Keystone Custom Decks is extremely busy and growing.”
