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 clients' dream decks in Lancaster County for over 30 years.

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

"Keystone just finished building our elevated screened-in porch and deck with firepit last month.  We are beyond thrilled and can't wait for some better to start using it!  Keystone handled every aspect with ease and superb communication.  We just can't say enough about how awesome it was dealing with Keystone.

Tourism is a major part of its economy with the Amish community being a major attraction. Because of William Penn's offer of religious freedom, ancestors of the Amish (and other religious groups that were persecuted in Europe) migrated to Pennsylvania. Lancaster was originally home to many Native Americans including the Shawnee and Lenape tribes.
