Keystone was started in 1983 by Amos Esh with a vision to craft beautiful, high-quality outdoor living spaces that bring families together.
What began as a small operation has grown into a leading outdoor living company serving Pennsylvania, New Jersey, Delaware, Maryland, and has expanded to New York, Tennessee, and Florida.
Our team is passionate about designing and building outdoor living spaces that reflect each customer’s unique style and enhance the way they live at home.
With over four decades of experience, we’ve built a reputation for excellence through integrity, craftsmanship, and attention to detail. From initial design to final walkthrough, we are committed to delivering an exceptional experience every step of the way.
At Keystone, we don’t just build projects—we create spaces where memories are made.
Such a great company!
Keystone is a great company, but the real winners are the team. The workers were amazing! Always had a smile on their face and cleaned up everyday! I told them they made it like “Christmas” every day with their fantastic work and skills. A friendship and bond was built between our family and them.”

Uour experience was nothing short of exceptional!
We recently had the pleasure of working with Keystone Custom Decks. They built a stunning pavilion, deck, and pergola for our outdoor space, and the entire process was seamless from start to finish.
Their blend of creativity, craftsmanship, and professionalism truly sets them apart in the industry. Thank you, Keystone Custom Decks, for helping us create our dream outdoor space!
