Composite decking is a smart choice for South Dakota homeowners who want a low-maintenance, weather-resistant outdoor space. Unlike wood, composite boards resist rot, fading, and warping, making them ideal for harsh winters and humid summers. Our team installs top brands like Trex, TimberTech, and Fiberon, giving you a deck that stays beautiful with minimal upkeep.
Composite decks provide homeowners with a modern, hassle-free alternative to wood. You won’t need to sand, stain, or seal year after year — simply rinse your deck with a garden hose to keep it looking great. These materials are engineered for durability, designed to resist mold, moisture, and insect damage, making them ideal for South Dakota’s changing climate. With a wide range of colors and finishes, composite boards allow you to customize your deck without sacrificing strength or style.

Composite materials are designed to handle South Dakota’s toughest conditions. Whether it’s heavy snowfall in Rapid City or summer heat in Sioux Falls, your deck will remain strong and safe. Boards are engineered with protective coatings that resist cracking, swelling, and insect damage, giving you peace of mind for years to come.

Today’s composite decking offers more than just durability — it gives you style flexibility. Choose from natural wood-look finishes, bold contemporary shades, or textured boards that provide slip resistance. Our designers work with you to match your home’s exterior and lifestyle, whether you want a rustic look, modern tones, or multi-level layouts with railings and lighting.
Our licensed deck builders bring precision and care to every project. From reinforced foundations to flawless board alignment, we ensure your composite deck not only looks great but also stands the test of time. With warranties on labor and materials, you’ll know your investment is protected. That’s why South Dakota homeowners choose Alliance Deck Builders for dependable results.
