"Jeremy and his crew did a fantastic job building our new deck. They were always on time, answered all of our questions, and did beautiful work."

- Dirk

"We had a 3-Season/ Covered deck designed and built. We chose Keystone Custom Decks👍 They were the best vendor we have ever used for a large scale project and we have done many. They were transparent about cost and timing but not cheap. Their craftsmanship was amazing. Visiting their showroom in Lancaster is worth the drive to help you pick out materials. 1st meeting at our home to measure and discuss was December. Mid January went to showroom to see renderings and look at materials. Didn't commit till April and got put on schedule for August. They said it would be 3 -4 weeks and that's what is was👍 workers came at 7 am and left 330 4:00 and cleaned up everyday!! Everyone I had to work with at Keystone were very friendly and professional. Elmer and his team were at my home for weeks and everyday they went home they cleaned up and did their best to help us live through a large scale project.
Bottom line if you're looking to build outdoor space take a look at Keystone Custom Decks.

- Jenn

"We love our new porch!! We find ourselves sitting out there quite often. We appreciated having the 3D renderings. We had only done one other construction project here - we appreciated patience among all the staff at Keystone. We did request multiple change orders along the way. The workmanship was top notch. Each crew that came out was professional, respectful and hard working. We would absolutely recommend Keystone to friends and families!"
