Why TimberTech Azek Excels in Illinois
TimberTech Azek's PVC composition makes it uniquely suited for Illinois's challenging climate:
- Zero Moisture Absorption: Unlike composite decking that contains wood fiber, Azek PVC absorbs zero moisture. This means no swelling, cupping, or warping during Illinois's freeze-thaw cycles — the most common cause of deck board failure in our climate.
- Mold and Mildew Proof: With no organic content to feed mold or mildew, Azek stays clean and hygienic even in shaded areas that trap moisture. This is especially valuable for Illinois decks that accumulate snow and ice for months each winter.
- UV-Resistant Cap: Azek's capped polymer technology includes UV stabilizers that resist color fading from Illinois's intense summer sun. The Vintage and Harvest collections maintain their rich color for decades.
- Lightweight and Easy to Work: PVC decking is lighter than composite, making it easier to handle during installation and reducing structural load on the framing system.
TimberTech Azek Warranty
TimberTech Azek carries one of the strongest warranties in the decking industry: a 50-year limited product warranty with 50-year fade and stain coverage. This warranty is fully transferable to subsequent homeowners, adding long-term value to your investment.
The warranty covers material defects, structural integrity, and resistance to checking, peeling, flaking, rotting, and termite damage. The fade and stain warranty guarantees that your deck will maintain its color within a specified range for 50 years under normal conditions.
When installed by a certified builder like Weatherguard Construction, your TimberTech Azek deck is also backed by our workmanship warranty covering the structural frame, fastening, and installation quality.
TimberTech Deck Design and Customization
Weatherguard's deck design team works with you to create a custom outdoor living space that maximizes your home's layout, views, and lifestyle. TimberTech Azek's versatile product line allows for stunning design possibilities that go far beyond a basic rectangular deck.
Popular design features for Illinois TimberTech decks include multi-level platforms with built-in stair transitions, picture-frame and herringbone inlay border patterns using contrasting colors, integrated bench seating and planter boxes, pergola and shade structure attachments, and dedicated zones for grilling, dining, and lounging. TimberTech's Azek line offers 10+ board colors across the Vintage and Harvest collections, and every color can be combined to create custom patterns and accents.
Our design process includes 3D renderings so you can visualize your finished deck before construction begins. We handle all permitting, HOA approvals, and structural engineering required by Illinois building codes, including proper footing depth for our frost line (42 inches minimum) and snow load calculations for covered structures.
The Weatherguard TimberTech Installation Process
Building a TimberTech Azek deck requires specialized knowledge and techniques that differ from traditional wood deck construction. Weatherguard's certified deck builders follow TimberTech's installation specifications precisely, ensuring proper gapping for thermal expansion, correct fastener patterns, and appropriate ventilation beneath the deck surface.
Our installation process starts with site preparation and footer excavation. In Illinois, deck footings must extend at least 36 inches below grade to reach below the frost line. We pour concrete footings with embedded post brackets, install pressure-treated framing with joist spacing per TimberTech specifications, and then install the Azek or PRO decking boards using concealed CONCEALoc fasteners for a clean, screw-free surface.
A typical 300-square-foot TimberTech deck takes our crew 5-8 days to complete from footer excavation to final railing installation. Larger multi-level projects may take 2-3 weeks. We coordinate all inspections required by your municipality and provide a complete walkthrough upon completion.
