“We recently had a deck built by Keystone Custom Decks in NY.  Our experience with Keystone was great.
I've built many decks back when wood was the only real choice for decking, but much has changed in the deck industry, and Keystone has remained current with their product selection and expertise.
Our deck now a work of art thanks to the knowledgable staff at Keystone Custom Decks."
-Phil Riehl

"This was by far the best contractor experience ever from the very beginning to completion.  When a few problems popped up, I thought it was awesome how the team handled it.  They immediately brought it to my attention, and they always had multiple options for solutions.  I highly recommend Keystone!"

- Tim Kalligonis

"We could not be happier with our new deck!  The crew was simply amazing!  I don't think I've ever encountered anyone who works harder or who keeps a project on track like them.  If you are thinking of a deck or porch remodel or addition - Keystone Custom Decks is the only way to go."

- Janet Brower

The first settlers were mostly Quakers from Massachusetts. It is now home to 14,275 people (as of the 2020 census).

These guys are the definition of professional. Always on time, always communicating, always respectful. We did a 1,000SQF composite deck with a screened in section, heaters, lighting, cable railing...the works and it all came out awesome. The attention to detail was incredible. You'll never hear a curse word or see a cigarette butt in your yard. We had the pleasure of having Anthony and Ernest as the primary foremen, but the whole team is incredible. I was honestly sad to see them go because it was such a pleasure to watch their progress! Strongest recommendation of any company I've worked with over the years on home projects!
 
- Trevor DiMarcio
 
"I've never dealt with a contractor that was so responsive, and stuck to their timeline. They came every morning and told us the schedule and stuck to it. They went above and beyond, and answered all our questions through the process and revised the project when we asked. We highly recommend Keystone for any outdoor projects." 
 
- Kyle and Agatha Edkin
