PVC and composite decking are both durable alternatives to traditional wood. PVC boards offer superior moisture resistance and longevity, while composite decking provides a natural wood appearance with balanced durability and lower upfront cost.
Choosing the right decking material often depends on how your outdoor space is used throughout the year. Decks here face snow buildup, spring thaw moisture, and strong summer sun, which can affect board performance over time. Materials like polyvinyl chloride decking and wood-plastic composite boards respond to these conditions in different ways.
When evaluating PVC vs composite decking, it becomes easier to decide which material will deliver the durability, appearance, and maintenance level your backyard needs. Read on to see how PVC and composite decking truly compare.
What is PVC Decking?
PVC decking is a synthetic decking material made from polyvinyl chloride (PVC). These deck boards contain no wood fibers, which makes them highly resistant to moisture, rot, and insect damage.
PVC deck boards use a cellular PVC core with a protective cap layer that blocks water absorption. This structure improves durability in wet conditions. In areas like Newmarket, decks face snow, rain, and freeze–thaw cycles throughout the year. PVC boards handle these conditions well because they resist swelling, mold growth, and surface fading. Manufacturers also add UV inhibitors and scratch-resistant coatings to extend lifespan.
What is Composite Decking?
Composite decking is a manufactured decking material made from a blend of recycled wood fibers and plastic polymers. These boards provide the look of natural wood while offering stronger durability and lower maintenance.
Composite deck boards use a wood-plastic composite (WPC) core covered with a protective cap layer. This outer layer improves resistance to moisture, stains, fading, and scratches. For many homeowners, this means less sanding, sealing, or staining over the years. Many homeowners choose composite decking when they want a durable deck that stays attractive with minimal upkeep.

PVC vs Composite Decking: A Detailed Comparison
PVC decking is fully synthetic, lightweight, waterproof, and highly resistant to mold and rot. Composite decking blends wood fibers and plastic, offering a more natural look with stronger density at a lower cost.
1. Cost Comparison
PVC Decking
PVC boards are typically the premium option. In Southern Ontario, installed prices often range from $90 to $130 per square foot. Homeowners comparing pvc decking vs composite decking cost often notice PVC costs more because the boards use solid polyvinyl chloride and protective cap layers.
Composite Decking
Composite decking usually costs $70–$110 per square foot installed in York Region deck projects. The boards combine recycled wood fibers and polymer resins, making them slightly more affordable. Many homeowners researching composite decking cost per square foot choose composite decking for its balance of durability and price.
2. Maintenance Requirements
PVC Decking
PVC decking requires minimal upkeep because the boards contain no organic wood fibers. The polyvinyl chloride core prevents water absorption, mold growth, and rot. In Newmarket’s humid summers and wet spring seasons, homeowners usually clean PVC decks with mild soap and water once or twice yearly.
Composite Decking
Composite decking also offers low-maintenance performance, but the wood-plastic composite core can retain surface debris if not cleaned regularly. In Southern Ontario’s freeze–thaw climate, leaves, snowmelt, and pollen may accumulate. Most homeowners wash composite decks once or twice per year to prevent staining and maintain color.
3. Durability and Lifespan
PVC Decking
PVC decking offers excellent durability because the boards contain no organic wood fibers. In Southern Ontario, decks face snow accumulation, spring thaw moisture, and frequent freeze–thaw cycles. PVC boards resist water absorption, which helps prevent cracking, swelling, and structural deterioration over time. Most PVC decks last 30–40 years with minimal performance loss.
Composite Decking
Composite decking uses wood-plastic composite boards that combine recycled wood fiber and polymer resin. These boards perform well in Ontario’s changing climate, but the organic fibers can absorb small amounts of moisture. With proper installation and ventilation, composite decks usually last 25–30 years in Newmarket’s seasonal weather conditions.
4. Appearance and Design Options
PVC Decking
PVC decking creates a clean, modern look because boards are manufactured from solid polyvinyl chloride with a protective cap layer. Many products feature smooth textures and lighter colours that reflect heat. In newer Newmarket subdivisions, homeowners choosing the best PVC decking boards often prefer these finishes for pool decks, patios, and contemporary outdoor living spaces.
Composite Decking
Composite decking delivers a warmer, natural appearance because boards contain recycled wood fibres blended with polymer resin. Manufacturers emboss wood-grain textures and multi-tone colours that resemble cedar or hardwood. Homeowners comparing composite vs. PVC decking often choose composite when designing traditional backyard decks attached to walkout basements, common in York Region homes.
5. Weight and Installation Difficulty
PVC Decking
PVC decking boards are lighter because they use cellular polyvinyl chloride construction with no wood fibers. Builders comparing pvc vs composite deck boards often find PVC easier to lift and position on deck framing. However, installers must leave expansion gaps because temperature swings and freeze–thaw cycles in Southern Ontario cause noticeable thermal movement.
Composite Decking
Composite boards are heavier due to their wood-plastic composite core made from recycled wood fibers and polymer resins. This density improves stability on joists, beams, and pressure-treated deck framing, which many contractors prefer for raised backyard decks. However, the additional weight can increase labour effort and affect overall composite decking installation cost on larger projects.
6. Environmental Impact
PVC Decking
PVC decking uses polyvinyl chloride polymer, a fully synthetic material produced through energy-intensive manufacturing. However, the boards resist moisture, rot, and insect damage. In Southern Ontario’s freeze–thaw climate, this durability reduces replacement waste. Professional builders also combine PVC boards with deck waterproofing systems to protect the structure below.
Composite Decking
Composite decking uses recycled wood fibers and recycled polyethylene plastics, forming a wood-plastic composite core. This process repurposes sawdust and plastic waste from manufacturing streams. Many products promoted as best composite decking material contain high recycled content, reducing landfill disposal and pressure on natural lumber resources.
PVC vs Composite Decking: Pros and Cons
