Built on Quality. Designed to Last.

At Stronghold Deck & Design, we believe great outdoor spaces start with thoughtful planning, quality materials, and a genuine commitment to doing things the right way. Based in Janesville, we proudly serve homeowners and contractors throughout Southern Wisconsin with a focus on custom deck design, premium materials, and practical outdoor solutions built to last.

What started as a passion for construction and design has grown into a company centered around helping clients create outdoor spaces that feel both functional and personal. From simple backyard upgrades to fully customized deck layouts and railing systems, we approach every project with attention to detail, clear communication, and a strong understanding of modern building practices and Wisconsin code requirements.

Our background in building materials and residential construction gives us a unique advantage when it comes to product knowledge, design planning, and project coordination. We work closely with homeowners, builders, and subcontractors to help simplify the process. Whether that means developing permit-ready deck plans, helping select the right products, or guiding clients through layout and design decisions.

Stronghold Deck & Design was built around the idea that professionalism and craftsmanship should go hand in hand. We value honest communication, reliable service, and creating projects that not only look great on day one, but continue to perform for years to come. Through our growing showroom, hands-on design approach, and commitment to quality products, our goal is to give clients confidence throughout every stage of their project.

Whether you're starting with a simple idea or a fully developed vision, we’re here to help bring it to life with stronger designs, better planning, and lasting results.
