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 dream decks in the Coatesville area for over 30 years.

“Words can't describe how happy we are with our deck.  After working with several contractors over the last year, Keystone was by far the best experience we have had making improvements to our home.
Communication was excellent, and they were even able to finish our job almost a month earlier than expected.
As an added bonus, every person I spoke to in the company were professional, kind, and respectful!  I can't recommend this company enough!”
-Alicia Andrews

- Brittany Detri

“We are so very pleased with our new deck!  The planning consultations were very thorough and even included a virtual video showing us what the new deck would look like on our own home.  The finished deck looks amazing.  I am just blown away by the quality and character of the entire team at Keystone!

- Emily Brunner

"Keystone Custom Decks replacing our old deck was a wonderful experience.  All parts of the process, from getting the estimate to the completion of the deck were expertly handled.  They created a deck that we love.  We are enjoying our new deck, and are happy to add more outdoor living space to our home.

- L. Mathes

"Superb craftsmanship!  Mike, Timmy, and Marlon were highly energetic, respectful, friendly, and extremely hardworking.  We couldn't be happier.  Highly recommend them!

- Steve Freytag

"After doing a lot of research, we settled on Keystone to add a new deck and rebuild an existing deck as part of a backyard/pool remodel.  The quality and workmanship of the decks resulted in two beautiful decks that we will enjoy for years.

- John Sincavage

The earliest recorded settler in the Coatsville area was a Scottish man named William Flemming. He settled in the area something in the mid-early 1700s. The area is now a prosperous town and home to 13,350 people as of the 2020 census. 

We are happy to serve Coatsville, zip code 19320, and the surrounding areas. 

Sandra T:  "We had a wonderful experience with Keystone Custom Decks. Daniel and his crew of Samuel, and Arlon were wonderful. They were consistently on time, and very professional. Their attention to detail was very apparent in all of their work. The craftsmanship was complimented on by others in the industry building decks for other companies, next door and down the street. The project manager of our new development complimented several times on the quality of work. We are very pleased with the final outcome. Thank you so much for such a beautiful job. The work was a 20 out of 10."
