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?

“These guys are the best!  From the initial construction to the 3D rendering to the permit process to the scheduling to the actual construction, Keystone made the process so smooth and easy.
I cannot speak highly enough of their customer service and overall project management from start to finish.  I also couldn't be happier with the final product.  It even looks better than the 3D renderings!  Thank you Keystone for making our dream deck come true!"

Penfield was first settled in the late 1700s and was incorporated as a town in 1810. It was named after a local businessman and politician. Like many other towns in this region, Penfield's economy was positively affected by the Erie Canal. This provided a transportation route for the local milling and manufacturing industries. In the 1900s, the town began to change to a more suburban community. As of 2020, Penfield is home to 34,404 people. 

We are happy to serve the Penfield community, zip codes 14526 and 14625, and all of its designated communities: Four Corners, Shadow Pines, Bay Trail, Panorama, and Penfield Center.
