Living in Michigan and Illinois means embracing the full spectrum of Midwest weather—icy winters, humid summers, and everything in between. At Miles Bradley Building & Remodeling, we’ve spent years helping homeowners design outdoor spaces that stand up to these challenges while staying beautiful and functional year-round. Whether you’re dreaming of a custom deck, a cozy sunroom, or a protective enclosure, choosing the right materials is the key to making your investment last.
Michigan and Illinois experience extreme temperature swings, from sub-zero winters to sweltering summers. With annual snowfall often exceeding 30 inches, outdoor structures face constant stress from freeze-thaw cycles, heavy snow, and high humidity. These conditions can lead to cracking, warping, rot, and mold growth. That’s why selecting materials that resist moisture and maintain their integrity is essential for durability and low maintenance.
The materials you choose for your deck, pergola, or gazebo will impact its longevity, aesthetics, and upkeep. Here’s a breakdown of the best options for Midwest weather:
Composites, like Trex (which we proudly install as a Platinum Contractor), are engineered to withstand harsh conditions. Made from a blend of recycled wood fibers and plastics, composites excel in freeze-thaw cycles because they don’t absorb water like wood, preventing cracks and splits. They’re also resistant to mold, fading, and insects, making them ideal for year-round use.
Why Choose Composite?
Options like pressure-treated pine, cedar, or redwood offer a natural look but require regular sealing and staining to combat moisture damage. While affordable, wood can warp or crack in Midwest winters if not properly maintained.

Fully synthetic and highly moisture-resistant, PVC is a great option for wet areas. Companies like Timber Tech offer advanced PVC products at competitive prices. However, it can feel less natural underfoot and may become a little more slippery when wet.
Lightweight, rust-proof, and low-maintenance, aluminum is excellent for enclosures or decks in high-wind areas. However, it may dent under heavy snow loads and can conduct heat or cold.
In regions like Michigan and Illinois, with dramatic temperature fluctuations, water infiltration is the enemy. Wood absorbs moisture, which freezes and expands, causing structural damage over time. Composites, on the other hand, feature a capped surface that repels water, maintaining dimensional stability. According to 2026 tests, composites outperform wood in weather resistance while offering the look and feel of natural wood.
At Miles Bradley, we’ve seen Trex decks endure decades of Midwest winters with minimal wear, proving their value as a long-term investment.
Investing in the right materials ensures your outdoor space thrives through Michigan and Illinois’ toughest seasons. At Miles Bradley, we specialize in custom solutions using top-tier products like Trex composites to create durable, beautiful decks and sunrooms.
