PVC vs Composite Decking: Which Is Right for Your Toronto Deck?
PVC and composite are both low-maintenance synthetic decking options, but they're made differently and perform differently. PVC is 100% plastic — ideal for wet areas. Composite blends wood fibre with plastic — more natural look, similar durability.
Quick Verdict
Best for wet areas (pools, rooftops): PVC. Best for natural appearance: Composite.
PVC Decking
Pros
- 100% waterproof — no wood fibre to absorb moisture
- Best for rooftop decks and pool surrounds
- Won't stain from pool chemicals
- Same 25-year lifespan as composite
- Excellent for high-moisture environments
Cons
- Higher cost ($50–$70/sqft)
- Less natural wood appearance
- Can be warmer underfoot in summer
- Fewer colour options than composite
Composite Decking
Pros
- More realistic wood grain appearance
- Wide colour selection across brands
- Slightly lower cost ($42–$75/sqft)
- Excellent for standard residential decks
- 25-year manufacturer warranties
Cons
- Contains wood fibre — can absorb moisture in substandard products
- Not ideal for constant standing water
- Slightly lower on waterproofing vs pure PVC
Side-by-Side Comparison
| Category | PVC Decking | Composite Decking |
|---|---|---|
| Cost | $50–$70/sqft installed | $42–$75/sqft installed |
| Lifespan | 25–30 years | 25–30 years |
| Maintenance | Annual cleaning only | Annual cleaning only |
Our Recommendation
For rooftop decks or pool surrounds, PVC is the clear choice — its 100% waterproof composition handles standing water and pool chemicals that can compromise composite over time. For standard backyard decks, composite offers a more natural appearance at a comparable or lower price.
Frequently Asked Questions
Is PVC or composite better for a pool deck?
PVC is better for pool decks. It's 100% waterproof and won't be affected by pool chemicals, chlorine, or constant moisture. Composite is also a good option but PVC's solid plastic construction handles pool environments better.
Which costs more — PVC or composite?
PVC typically costs $50–$70/sqft installed in Toronto. Composite ranges from $42–$75/sqft. Budget composite brands can be cheaper than PVC; premium composite brands are comparable or more expensive.
Is PVC decking hotter than composite in summer?
Both can retain heat in direct sun. PVC tends to run slightly warmer than capped composite. Light colours and products specifically engineered for lower heat retention (like AZEK TimberTech) minimize this issue.
Does PVC or composite look more natural?
Composite looks more natural. It contains wood fibre and is available in more realistic grain patterns. PVC has a more uniform appearance that's harder to mistake for real wood.
Can PVC decking be used on a rooftop deck?
Yes — PVC is the top choice for rooftop decks. It's 100% waterproof, handles the drainage requirements of pedestal systems, and won't be affected by ponding water that sometimes occurs on flat roofs.
How long do PVC and composite both last?
Both last 25–30 years with proper installation and minimal maintenance. The main difference is in wet environments, where PVC outlasts composite by several years.
