We also install premium railing systems, built-in LED lighting, hidden fastener systems, and structural framing engineered for Illinois's freeze-thaw cycles and snow loads.
Decks Cost Factors in Illinois
Deck construction costs in Illinois depend on the deck size, materials selected, elevation, design complexity, and features like railings, stairs, and built-ins. Here are typical ranges:
- Composite deck (300 sq ft): $12,000 – $22,000 including railing and stairs
- PVC deck (300 sq ft): $15,000 – $28,000 including railing and stairs
- Multi-level or wraparound deck: $25,000 – $60,000+ depending on size and features
- Screen porch or covered structure: Add $8,000 – $25,000 to deck cost
The framing system (typically pressure-treated lumber or steel) accounts for a significant portion of the cost. Weatherguard uses engineered framing designed for Illinois's climate, including proper footing depths below the frost line and structural connections rated for snow loads and wind uplift.
Comparing Decks Options
Modern decking materials offer dramatic improvements over traditional wood. Here's how the leading options compare for Illinois homes:
Composite vs. PVC: Both are low-maintenance alternatives to wood. Composite decking contains a blend of wood fibers and plastic, while PVC contains no organic material. PVC is more moisture-resistant (ideal for pool decks and ground-level applications), lighter, and won't grow mold. Composite offers a slightly more natural wood look and is typically 15-25% less expensive.
TimberTech Azek vs. Trex: Azek is a PVC product with zero organic content for the ultimate in moisture resistance. Trex is a wood-plastic composite that offers excellent value with strong warranties. Both resist fading, staining, and scratching. Azek is the premium choice for homeowners who want the longest lifespan and highest performance; Trex delivers outstanding results at a more accessible price point.
Composite vs. Cedar: While cedar has a beautiful natural appearance, it requires annual staining or sealing, is susceptible to rot and insect damage, and typically lasts 10-15 years in Illinois's climate. Composite and PVC decking require no staining or sealing, resist insects and rot, and last 25-50+ years — making them the clear long-term value winner despite the higher initial investment.
Storm Damage and Decks in Illinois
Illinois's severe weather — including hail, high winds, heavy snow, and ice storms — can cause significant damage to your home's decks.

We maintain emergency response capability year-round and can typically provide a damage assessment within 24-48 hours of a major storm event. Our goal is to restore your home to pre-storm condition quickly and professionally while making the insurance process as stress-free as possible.
Our Decks Process
Weatherguard follows a proven, systematic process for every decks project to ensure consistent quality and customer satisfaction:
- Design Consultation: Our deck designer visits your home, evaluates the site, discusses your vision and lifestyle needs, and creates a custom design with material recommendations and a detailed estimate.
- Permitting: We prepare construction drawings, submit permit applications, and manage the approval process with your local building department. Most Illinois communities require permits for new deck construction.
- Site Preparation & Footings: We excavate and pour concrete footings below Illinois's frost line (42-48 inches depending on location) to prevent frost heave and ensure a stable foundation.
- Framing: The structural frame is built using pressure-treated lumber or steel with engineered connections, proper beam sizing, and code-compliant joist spacing to support the deck's load requirements.
- Decking Installation: Your chosen decking boards are installed with hidden fastener systems for a clean, screw-free surface. We pay careful attention to board spacing, end joints, and picture framing details.
- Railings, Stairs & Accessories: Custom railing systems, stairs, post caps, lighting, and other features are installed to complete your outdoor living space.
- Final Inspection & Walkthrough: We schedule the required building inspection, clean the site completely, and walk you through your new deck including care and maintenance guidelines.
