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 Wilmington area for over 30 years.

“We could not be happier with the finished product that Keystone installed.  The schedule was extremely well executed from start to finish.
The quality of the work was outstanding.  The addition on the back of our house looks like it was built with the original construction.
In summary, we expected the covered patio to look great, and Keystone exceeded our expectations.”
-Karen Hickes

“Keystone Custom Decks is an amazing company!  Very well run.  Extraordinarily professional in their approach in both the quoting and presentation process and the job completion.  The quality of the work is first-rate and the people at Keystone are wonderful.

- Tom French

“We used Keystone for a recent deck replacement project.  They were patient as we changed our mind on the design several times.  They did a great job of communicating throughout the project, and the job was done in a timely manner with high quality.

- Joe Keer

"Couldn't be happier.  Their sales associate Mahlon made the design and specification process simple and fun.  Keystone was not the least expensive option, but they were the most trustworthy.  The team that built the deck was awesome.  They were all beyond friendly and it was obvious that they knew what they were doing.

- Joe Roth

"From the start, Marv worked very hard with me to come up with a great design for my deck and gazebo.  The builders Mike, Allan, and their crew were meticulous in their work, very polite, conscientious, and respectful.  It was a pleasure to work with such a professional company.

- Sandra Cheung

"Having just come off a horrific pool construction project with a horrible company, we were very nervous about another group of contractors.  However, Keystone has happily proven us wrong in our worries, and we could not be happier with our finished project.  Our project was everything we hoped it would be and more.

- Chris O.
