Understanding the pros, cons, and real differences that matter
Choosing between composite decking and pressure-treated wood is one of the first big decisions homeowners face when designing a new deck. Both can look great and perform well in Ontario’s climate — but the long-term experience is very different.
Here’s a clear, practical breakdown to help you choose what’s best for your backyard.
1. Composite Decking: Low-Maintenance, Modern, and Long-Lasting
Composite decking has become the preferred choice for homeowners who want something durable, stylish, and low-maintenance. It’s engineered to resist moisture, fading, and wear — which makes it ideal for the freeze–thaw cycles we get in Ontario.
Brands like Trex set the standard for modern composite performance, but the overall advantages apply to composite in general:
Benefits of composite decking:
- No staining or sealing required
- Won’t warp, rot, or splinter
- Colour stays consistent for years
- Modern, high-end grain patterns
- Longer lifespan than wood
Composite costs more upfront, but you save time and money over the long term because there’s virtually no maintenance.
2. Pressure-Treated Wood: Budget-Friendly With More Upkeep
Pressure-treated lumber is the most affordable decking material and gives you a classic wood look. It’s easy to customize and cut, but it requires ongoing care — especially in an Ontario climate.
Pros:
- Lowest upfront cost
- Natural wood appearance
- Easy to modify or customize
But expect:
- Regular staining and sealing
- Colour fading from sun exposure
- Splinters, checks, and cracking over time
- Shorter lifespan than composite
Pressure-treated decks can still look great, but they require ongoing work to keep them that way.
3. Lifespan & Long-Term Value
Here’s where the difference becomes clear:
- Composite decking: typically lasts 25–30+ years
- Pressure-treated wood: 10–15 years (with maintenance)
Wood is cheaper now, composite is cheaper long-term.
If you plan to stay in your home for several years, composite usually ends up being the better investment.
4. Maintenance Requirements
This is often what helps homeowners make the final decision.
Composite:
- Soap + water is basically all you need
- No sanding, sealing, or re-staining
- Colour stays consistent with minimal effort
Pressure-Treated Wood:
- Clean + re-stain every 1–2 years
- Regular inspection for cracks or splinters
- Occasional board replacements
- More time + money invested over the deck’s life
If you want a “set it and forget it” outdoor space, composite wins easily.
5. Appearance & Design Options
Composite boards offer more variety in texture, grain, and colour. Many homeowners choose composite because it better supports modern backyard designs — especially larger builds, pool decks, and multi-level layouts.
Pressure-treated wood has a traditional look and can be stained in different tones, but will eventually fade without constant care.
6. So… Which One Is Best for Your Backyard?
It depends on your priorities.
Choose Composite If You Want:
- Low maintenance
- Modern aesthetics
- Long-term durability
- A deck that ages well without upkeep
Choose Pressure-Treated Wood If You Want:
- The lowest upfront price
- A traditional wood look
- A short-term or budget-conscious build
Both can be great choices — it just depends on the experience you want over the next decade.
