Frequently Asked Questions
What is the best decking material for Chicago weather?
Premium capped composite decking from brands like Trex, TimberTech, or Fiberon performs best in Chicago's climate. These materials resist moisture penetration during freeze-thaw cycles, maintain color despite UV exposure, and require minimal maintenance. PVC decking offers even greater moisture resistance for areas with extreme exposure. For those preferring natural wood, exotic hardwoods like ipe provide exceptional durability but require seasonal maintenance commitment.
How long do different decking materials last in Chicago?
Material lifespan varies significantly: pressure-treated pine lasts 15-20 years with proper maintenance, cedar and redwood 20-25 years, mid-grade composites 25-30 years, premium composites and PVC 30-50 years, and exotic hardwoods 25-40 years depending on maintenance. Chicago's harsh winters and humid summers accelerate wear on materials not properly maintained or suited to the climate.
Is composite decking worth the extra cost?
For most Chicago homeowners, composite decking proves cost-effective over its lifespan. While initial material costs run $8-$15 per square foot versus $3-$6 for pressure-treated wood, composites require virtually no maintenance beyond periodic cleaning. Wood decking needs annual staining and sealing costing $200-$500 yearly. Over a 25-year period, composite total ownership costs often equal or beat wood while providing superior performance and lower ongoing effort.
Can I install decking materials myself or should I hire professionals?
While experienced DIYers can install decking materials, professional installation ensures proper technique, maintains manufacturer warranties, and addresses Chicago building code requirements. Composite materials require specific fastening methods, expansion gaps, and ventilation that impact long-term performance. Professional installers also handle structural framing, proper flashing, and drainage systems critical to Chicago climate durability. Most premium composite warranties require certified installer involvement to remain valid.
Do composite decks get too hot in summer sun?
Dark composite boards can become hot in direct summer sun, though newer heat-mitigating technologies reduce surface temperatures by 20-30°F compared to earlier composites. Choosing lighter colors, incorporating shade structures, or selecting brands with cool-deck technology addresses heat concerns. Strategic positioning to maximize morning shade or afternoon tree cover also helps. PVC decking generally stays cooler than wood-composite blends due to different material properties.
What maintenance does composite decking actually require?
Composite decking needs periodic cleaning with mild soap and water—typically twice yearly. Remove leaves, pollen, and organic debris that can promote mold growth in damp conditions. Address spills promptly to prevent staining on lighter colors. Annual inspection of fasteners and structural connections ensures safety. Unlike wood, composites never need staining, sealing, or painting, saving hundreds of dollars and many hours annually compared to natural wood maintenance requirements.
Can you mix different decking materials in one project?
Yes, many contemporary deck designs combine materials strategically. Common approaches include using composite boards with contrasting composite borders, mixing wood structural elements with composite decking surfaces, or creating distinct zones with different materials. Ensure proper transitions between materials and verify that structural framing supports all material types used. Professional designers can create cohesive looks that maximize each material's strengths.
How do decking material choices affect resale value?
Quality decking materials typically return 60-80% of installation costs in added home value. Premium composite and well-maintained exotic hardwood decks appeal most to buyers, who appreciate low-maintenance outdoor spaces. Dated or deteriorating wood decks may actually detract from property value. Chicago buyers particularly value materials proven to withstand local climate challenges. Professional installation and maintained warranties further enhance resale appeal and buyer confidence.
What decking materials work best for shaded areas?
Shaded deck areas stay damper longer, promoting mold and mildew growth. Composite materials with antimicrobial additives resist organic growth better than untreated wood. Ensure adequate ventilation beneath shaded decks and increase cleaning frequency in these areas. Some composite brands specifically formulate products for low-light applications. Pressure-treated wood in shade requires diligent maintenance to prevent rot and decay from prolonged moisture exposure.
