Decks Built for Wisconsin's Unique Conditions
Weather-Ready Construction in Every Region
From humid summers in Racine to snowy winters in Green Bay, our decks are built to handle it all. We account for snow loads, freeze-thaw cycles, and drainage during every build. All materials are rated for Midwest weather, and our fastening methods reduce warping and premature wear. Whether it's a pool deck in Oshkosh or a multi-level cedar wrap in Madison, we use products and techniques that extend your deck’s life through every season.
Every Project Starts With a Detailed Plan
On-Site Consultations & 3D Renderings
Before we build, we listen. Every project begins with a free, in-person consultation to review space, grade, materials, and goals. From there, we deliver detailed 3D design renderings so you can see your deck before it's built. Our planning process includes layout options, structural specs, permits, and product samples to ensure every client feels confident moving forward—no surprises, no guesswork.
