“What a great experience with this contractor. After building my home and dealing with many different contractors I can safely say that Keystone is a cut above the rest. They handled all the bumps and dips that come with a larger project in stride and made our outdoor space amazing. The attention to finishing detail was greatly appreciated!”

Custom Deck Builder in TN

Are you wanting to build a deck and create your dream outdoor space, but you don’t know where to start?

At Keystone Custom Decks, we know how overwhelming the design and construction process can be.  That is why we offer turn-key construction, from design to construction, with our custom deck design and installation.

We welcome our clients’ most imaginative ideas for custom deck design. We often build decks that come with a full outdoor kitchen that match perfectly to adjacent dining areas. 

Our designers also enjoy crafting curved and other custom deck shapes with deck railings that add a distinctly modern flair to your outdoor space. Finally, homeowners often love accessorizing their outdoor living spaces with a firepit or fireplace, water features, or masonry features that add character and your unique style to your outdoor project.

To ensure that our custom designs match your dreams, we provide every client with a full 3D rendering of what their deck, porch, or patio will look like before a contract is ever signed. This allows us to work with you to devise the ideal design — plus, our realistic rendering ensures you love the way your project will look before work begins.

At Keystone Custom Decks, we take pride in providing expert deck construction to our customers, no matter how small or big the project.

Our team of in-house builders has several decades of combined custom deck construction to bring to your project and your backyard.
