Composite vs. Wood Decks: Which Is Best for Canadian Winters?

If you’re a homeowner in London, Ontario or the surrounding areas, you already know how harsh Canadian winters can be on your outdoor spaces. When planning a new deck or upgrading an existing one, choosing the right material is crucial—not only for visual appeal and long-term durability but for withstanding snow, ice, and freezing temperatures. At Mammoth Property Services, we help local homeowners enjoy beautiful, usable decks year-round. In this guide, we’ll compare composite and wood decks to help you decide which is best suited for Canadian winters.

Understanding Composite Decks

Composite decking is made from a blend of recycled wood fibres and durable plastic, resulting in a material that’s both eco-friendly and engineered to resist many common problems associated with wood. This advanced manufacturing process creates boards that mimic the appearance of natural wood, offered in a variety of colours and finishes.

Key Benefits of Composite Decks:

1. Low Maintenance: Composite decks require minimal upkeep. There’s no need for staining, sealing, or frequent cleaning; a simple wash with soap and water does the trick.
2. Weather Resistance: Composite materials are highly resistant to moisture, rot, and warping, making them ideal for snowy, wet winters in Ontario.
3. Slip-Resistance: Many composite boards are designed with textured surfaces to provide better grip, even when wet or frosty, improving winter safety.
4. Longevity: With proper installation, composite decks often last 25-30 years or more, standing up well to freeze-thaw cycles.
5. Sustainability: Many products use recycled content, appealing to eco-conscious homeowners.

Potential Drawbacks:

Composite decks typically have a higher upfront cost than wood. Additionally, while they handle temperature swings well, some brands may become slippery under heavy ice, though this can usually be mitigated with proper cleaning and snow removal practices.

Understanding Wood Decks

Traditional wood decks—using cedar, treated pine, or redwood—have long been a favourite among Canadian homeowners for their natural beauty, warmth, and timeless appeal. Wood is durable and strong when maintained properly, making it a classic choice for outdoor spaces.

Key Benefits of Wood Decks:

1. Natural Aesthetics: Many homeowners love the look and feel of real wood. Each board is unique, adding character to your backyard.
2. Cost-Effective: Pressure-treated wood is generally less expensive upfront compared to composite decking.
3. Repairable: Individual boards can be easily replaced if damaged, making ongoing repairs straightforward.

Potential Drawbacks:

Wood decks require ongoing maintenance—including annual staining or sealing, and regular inspections for rot, splinters, and insect damage. In Canadian winters, unprotected wood can absorb moisture, leading to warping, cracking, or premature decay. Snow and ice removal with metal shovels can easily scratch wood surfaces, which may require touch-ups in spring.

Composite vs. Wood Decks in Canadian Winters: The Key Differences

Durability

Composite decking is highly resistant to freezing and thawing cycles that are so common in Ontario winters. It doesn’t absorb moisture like wood, so you’re less likely to encounter issues like rotting, splitting, or heaving.

Maintenance

Compared to composite, wood decks need far more maintenance in winter—clearing snow and ice, resealing, and checking for damage. Composite decks, on the other hand, require only regular cleaning and basic snow removal, without worry about damaging the surface.

Appearance and Feel

While composite decking does a great job of imitating natural wood, purists may still prefer the authenticity of cedar or pine. However, modern composites come in a wide array of realistic wood-look designs that complement any home’s aesthetic.

Cost Over Time

Though composite decks have a higher upfront cost, their low maintenance needs and superior lifespan can save you money in the long run—especially when factoring in repairs and refinishing associated with wood decks.

Which Deck Is Best for Your Home?

If you want a low-maintenance, long-lasting deck that stands up to Ontario’s winter extremes, composite decking is often the best choice for busy families or those seeking hassle-free ownership. However, if you cherish the look of natural wood and are prepared for regular upkeep, wood decks remain a timeless, budget-friendly option.
