Deck Builder in Monroe County, NY

Make your dream outdoor living space a reality with a custom deck and additional features!

"Our deck came out as planned, it is beautiful. The Keystone team was very professional, polite, and accommodating. The employees were friendly and respected our interest to socially distance while still keeping us informed of the progress and options. The workmanship was only eclipsed by their work ethic. I would highly recommend Keystone."

- Helen Kordela

"This is our second time working with KCD and can't praise them enough. The sales process was seamless and communication was clear, we got 3d renderings of the finished product that were pretty much spot on to the finished product. The work was beyond professional."

- Ray Stanton

"What can I say... QUALITY & SERVICE! This is the second deck we've had built with Mahlon and Keystone Custom Decks, and we're even happier this time around. To see what they've grown into is Amazing, but not so surprising. When you love what you do, and you genuinely like to take care of people, being successful is a by-product!"

- Pat Kalaboke

    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 custom decks 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.  From the first meeting with sales, Keystone was timely and professional, and a great company to work with.
The project was begun even earlier than our planned schedule.  We are awaiting warm weather to enjoy our new deck!"

- Tiff Ossichuck

"We love our new deck! The entire experience was relaxed and professional from the initial quote process with Mahlon through to the final product with Anthony and his crew of very hard workers. The gift of wine and two etched wine glasses was a lovely finishing touch!"
