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 Cecil County for over 30 years.

“We recently hired Keystone to replace our existing wooden deck with a new composite deck and roof.
Everything about them is Class A; from their sales rep to the showroom to the crew.  They cleaned up every day, and they showed up when they said they would.
Their workmanship was impeccable.  We truly miss not having them at our house."
-Alan Roseman
