Wood vs. Composite Decking: What’s Best for Your Alberta Property?
A well-built deck is more than just an outdoor structure—it's a place to relax, entertain, and enjoy the beauty of your own backyard. But when it comes to materials, many homeowners face the same question: Should I build a deck with natural wood or low-maintenance composite?
If you're planning a deck build in Alberta, the answer depends on your budget, maintenance tolerance, climate, and aesthetic preferences. In this post, we break down the key differences between wood and composite decking, including cost comparisons, pros and cons, and how each holds up to Alberta's harsh winters.
Wood Decking: Classic and Affordable
Wood has been the go-to material for decades thanks to its natural look, affordability, and versatility.
Pros:
Lower upfront cost compared to composite
Natural grain and warmth
Easy to custom-stain or paint any colour
Repairs (like replacing a board) are simple
Cons:
Requires annual maintenance (staining, sealing)
Susceptible to splitting, rot, or warping
Vulnerable to insects and moisture damage
Average Cost in Alberta (as of 2025):
Pressure-treated wood: $30–$45/sq. ft. (installed)
Cedar: $40–$60/sq. ft. (installed)
Exotic hardwoods (e.g., Ipe): $65–$100/sq. ft.
Alberta Climate Tip: Cold winters, snow buildup, and freeze-thaw cycles can cause untreated wood to warp or crack. Choose pressure-treated or cedar and apply a high-quality sealant annually.
Composite Decking: Durable and Low Maintenance
Made from a blend of recycled wood fibers and plastic, composite decking offers a sleek, modern look with less upkeep.
Pros:
Low maintenance (no staining or sealing)
Less likely to warp and won’t splinter or rot
Resistant to mold, moisture, and insects
Available in a wide range of colours and styles
Cons:
Higher upfront cost
Can get hot underfoot in direct sun
May fade over time (with lower-end brands)
Average Cost in Alberta (as of 2025):
Composite boards: $55–$75/sq. ft. (installed)
Premium brands may cost more, especially with hidden fasteners or upgraded railings.
🔎 Alberta Building Code Note: Composite decking is fully approved for residential use, but must meet flame-spread and structural requirements. Work with a licensed contractor to ensure compliance.
Maintenance Showdown
| Task | Wood | Composite |
|---|---|---|
| Staining/Sealing | Every 1–2 years | Not required |
| Cleaning | Sweep + pressure wash | Soap + water |
| Rot/Mold Treatment | May be needed | Unlikely |
| Lifespan | 10-20 Years with Proper Care | 25-50 Years |
Sustainability Considerations
Wood is a renewable material but often sourced from forests with varying sustainability practices.
Composite is made from recycled plastics and wood waste, reducing landfill impact—but is not biodegradable.
Aesthetic Comparison
Wood offers a natural, rustic charm, perfect for traditional homes or cabins. Composite delivers clean lines and colour consistency, ideal for modern designs or homeowners who want a polished look with zero fuss.
Pro Tip: You can mix materials—use wood for framing and composite for the decking boards—for a balance of cost and durability.
