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.
Building a two-story deck complete with a patio or a porch is a bit more complicated than adding a basic square deck. That’s why you want to trust your custom deck to a company that specializes in it.
The more covered spaces, features, and accessories you add to your custom deck, the more complicated it becomes in design and construction.
Unfortunately, some less-experienced companies and contractors may not know how to safely build your dream backyard deck or ensure that it meets stringent building codes.
So, while some companies shy away from in-depth projects like this — at Keystone Custom Decks, we embrace it!
In fact, we have built our business on ambitious and precise deck installation along with our custom deck designs.
Our team of in-house builders has several decades of combined custom deck construction to bring to your project and your backyard.
