    Be Proud
    of Your Space

     Become the envy of the neighborhood with your beautiful outdoor space.

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 Yardley and nearby areas for over 30 years.

“Anthony and the crew are extremely polite, courteous, and punctual (you could set your watch to their start time).

Each day they cleaned up such that you’d barely know they were there besides seeing the progress of construction.

Everyone was accommodating and patient with our questions and we couldn’t be happier with the deck, the pergola, the under-deck roof system, it really finishes the yard!

“We recently had our deck and patio redone by Keystone Custom Decks. Let me start off by saying it was the best home improvement experience we have ever had. The entire staff was amazing. Overall, we had a wonderful experience with Keystone Custom Decks and I would definitely recommend them to others.

- Stacey C.

Mahlon and his team did an awesome job! Perfection is not a strong enough word! The craftsmanship is phenomenal! Highly recommend!

- Michael K.

"Mahlon wonderfully explained every aspect of the project during our first meeting. The contract was perfectly in line with that conversation, and the execution of the project was exemplary. We really appreciated their attention to detail and working with us during the project to ensure our satisfaction.

- Brian P.

"This project has made our home so much more functional. Mahlon, Anthony, and their team were consistently professional, hard-working, open-minded to our ideas, and even the inspectors remarked on the beautiful craftsmanship and how easy they are to work with. We had gotten quotes from a handful of other contractors and are so glad we used Keystone in the end!

- Rachel P.

"Keystone Custom Decks just completed an outdoor landscape staircase project for us. Mahlon was extremely helpful and customer-focused as we worked through design options. Nate and his Team were prompt, courteous, and neat as they constructed the staircase in rough terrain and in very difficult weather conditions.

- Monica G.
