    of Your 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 the general Havre De Grace area for over 30 years.

“We cannot say enough about our positive experience with Keystone Custom Decks.  We met with a few contractors, but Keystone just seemed right to us with the vision and level of detail on what's best for us.
From the moment that Matt with us and designed the outdoor space, through to the end of the project, we cannot say enough good things.
I would not hesitate for one second to spend the money to get the deck and patio of our dreams and have it done from start to finish by the best in the business.”
-Steve & Amanda Vogelsong

“Keystone Custom Decks recently completed our deck project which included a covered porch. From start to finish everyone we worked with and the process itself were top notch. Ron did a great job talking us through all of our options to come up with our final design. The crew of Daniel and the guys were extremely professional and a real pleasure to work with. They were extremely communicative all along the way.”

- Mike Cohen

“We recently had Keystone Custom Decks design and complete an outdoor living area project to include a custom roof over our patio, along with a pergola to include a retractable top canvas and side curtain. Their creativity and knowledge provided us with a top notch solution to create shade on our patio since we get the afternoon sun. The entire process from beginning to end was handled professionally and completed with outstanding quality.

- Suzanne

"Keystone just finished our deck in Dresden NY. Work was high quality. The process was extremely professional. Every inquiry was promptly answered and addressed. Mahlon, Nate and Brian are top notch. Would highly recommend.

- Thomas Legutko

"From start to finish, Keystone Custom Decks was top notch. We could not be happier with the finished product. The crew were respectable, professional, and made sure they communicated along the way the progress and steps.  Highly recommend to anyone interested in getting their deck and patio done!

- Joshua Kyler

"We had Keystone recently complete our patio and we love the results! It was great working with Mahlon Esh, Nathan Esh and Jaydon Rieh.  During the project, they were in frequent communication with us regarding updates, flexible with last minute changes we requested, reasonable in price when we compared other quotes. Very professional, courteous, and skilled at what they do.
