    Be Proud
    of Your Space

     Become the envy of the neighborhood with your beautiful outdoor space.

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 Montgomery County and nearby areas for over 30 years.

“We love our new deck! After 18 years of living in our house with an awful brick patio we decided to get a deck. Keystone was timely and professional, and a great company to work with.

Loved the 3D renderings-that was a huge help since my husband couldn't be at the initial meeting.

The crew even worked through the bitter cold temperatures of December to complete the project on time. We are anxiously awaiting warm weather to enjoy our new deck!

“I had the pleasure of working with Ron initially, who was incredibly patient with me for a very long time as we worked through design ideas. He presented us 3-D renderings of the project and while that was impressive itself, the finished product was beyond anything we could have imagined. It's absolutely beautiful!

- Scott M.

“I cannot speak highly enough of their customer service and overall project management from start to finish. During the design process, Joe and his team offered so many different options to ensure I got the design I wanted but also stay within my budget. He also commuted to our house for each of our design meetings to make everything as convenient as possible.

- Anthony S.

"Daniel and Levi and the whole Keystone team did an amazing job and we could not be happier. From the start of the project, Ron told us what to expect and the Keystone team nailed it. The Keystone Teams' commitment to their craft is great to see and it comes through in how they approach the project and our family.

- Tom G.

"We could not be more pleased with our deck and patio. From the initial meeting with Joe Lehman to the completed walk-though with Daniel B. it was a professional experience with outstanding results. We wanted a quality product and Keystone Custom Decks delivered that for us.

- Donna S.

"Excellent craftsmanship, all the way down to the tiniest details! Josh and the crew were very friendly and courteous. I would highly recommend Keystone Custom Decks to anyone. Looking forward to working with them again in the future!

- Doug M.
