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 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 a custom deck builder for over 30 years.

“Mahlon and the crew did a fantastic job with our deck.  They were spot on with the design, flawless craftsmanship, and communication all along the way.

All of my neighbors have asked about our deck and how incredible it is.  I would highly recommend Keystone to anyone who wants a fabulous deck with amazing customer service."

"We had a great experience with Mahlon and his team at Keystone Custom Decks. From the initial meeting to the final touches, everything was very well executed and beautifully done. Every member of the team worked very hard and they wasted no time. They disassembled our old deck in minutes and constructed a beautiful deck, with railings, gate, and a pergola in 2 days. Despite the quick turnaround the work was meticulously done. The yard was left clean and in good shape after both days of work. All employees were respectful and hard-working. Mahlon was very attentive to his emails and responses were very quick. He really stands by his high quality work; when there was a small issue with the gate, he immediately sent someone to our house to replace the flawed part, no questions asked. We enjoyed the nice touch at the end too with the box. The finished product is outstanding! Thank you to everyone at Keystone Custom Decks!"

- Brian and Kaitlin Stone

"Keystone Custom Decks uses a process that is customer and quality focused, thorough, and professional. The initial meeting, the quote with the drawing(s) and 3-D renderings, and the build process were all very satisfying. Work started on my deck during the week prior to Thanksgiving 2019, as promised, and it was completed on time. The build team started each day on time and they were all very professional and respectful. They worked hard, not wasting any time, and operated like a real team rather than a collection of workers. The quality of their workmanship is a reflection of their work ethic and the values of Keystone Custom Decks. The finished product is definitely great in appearance, functionality and usability."

- Ensley Townsend

"Keystone Custom Decks exceeded our expectations in every way! We had a $100,000+ redo of our front entrance, side entrance, 53 step entrance from the lake shore and a 2 story deck with a spiral staircase. The design work was complete with a CAD design and every detail was planned out in advance. We were on a tight timeline for most of the project which was completed in 3 phases. They showed up on the day agreed upon. The workers showed up on time, every time. They completed the projects on time. They were all hard workers and clearly experts in their field. The organization is very honest. If there is a problem as most projects do, they tell you and work to fix it. Trust in a contractor can be a difficult thing to fine, but not with Keystone Custom Decks. They are the best."

- Robert Wagner
