Expert Trex Deck Construction in Illinois
Weatherguard Construction designs and builds custom Trex composite decks for homeowners across Illinois. Trex invented the composite decking category more than 25 years ago and remains the world's largest composite decking brand — a track record that matters when you're investing in an outdoor space that must survive Illinois winters.
Our deck crews handle every phase of your project: design and 3D rendering, permits, frost-depth footings, framing, Trex decking and railing installation, and finishing details like lighting and fascia. The result is a deck that looks showroom-new each spring without the sanding, staining, and sealing wood demands.

Why Trex Performs in Illinois
Trex boards are made from 95% recycled materials — reclaimed wood fiber and polyethylene film — wrapped in a durable integrated shell that resists fading, staining, scratching, and mold. Unlike wood, Trex won't crack, splinter, or rot through Illinois's 40+ annual freeze-thaw cycles, and it never needs staining or sealing. Spring maintenance is a soap-and-water wash.
Just as important is what's under the boards. Illinois code requires deck footings at least 36 inches below grade to get beneath the frost line, and proper ledger flashing is what keeps a deck attached safely to your home through decades of snow load. Weatherguard's crews build the structure to code and to manufacturer specifications, so the 25-50 year warranty on your Trex boards is matched by a frame built to last as long.
Trex's hidden fastener systems give walking surfaces a clean, screw-free look while allowing the boards to expand and contract naturally with temperature — critical across our extreme seasonal swings.
Trex Warranty Coverage
Trex backs its decking with some of the strongest warranties in outdoor living: a 50-year Limited Residential Fade & Stain Warranty on Transcend Lineage and Transcend, 35 years on Select, and 25 years on Enhance, alongside limited structural warranties against material defects, rot, and splintering.
Weatherguard adds its own workmanship warranty covering the structure we build — footings, framing, ledger attachment, and installation. Between the manufacturer's board coverage and our construction guarantee, your Trex deck is protected from the ground up.
Designing Your Illinois Trex Deck
Great decks are designed around how you'll actually use them: grilling zones near the kitchen door, conversation areas sized for real furniture, stairs placed for yard flow, and railings that frame views instead of blocking them. Weatherguard's design process includes detailed renderings so you can see your deck — board colors, railing styles, lighting — before we build it.
Popular Illinois upgrades include picture-frame borders in contrasting colors, drink rails, under-deck drainage systems that create dry storage or patio space below, integrated riser and post-cap lighting for summer evenings, and low-voltage systems that extend the season. Most Trex deck projects complete in 1-3 weeks depending on size and complexity, including permit and inspection time.
