Upfront Cost Comparison
| Material | Cost/sq ft (Materials) | Cost/sq ft (Installed) | 200 sq ft Deck | 400 sq ft Deck |
|---|---|---|---|---|
| Pressure-treated wood | $8–$15 | $25–$40 | $5,000–$8,000 | $10,000–$16,000 |
| Cedar | $12–$22 | $35–$55 | $7,000–$11,000 | $14,000–$22,000 |
| Composite (mid-range) | $15–$30 | $45–$65 | $9,000–$13,000 | $18,000–$26,000 |
| Composite (premium) | $25–$40 | $55–$75 | $11,000–$15,000 | $22,000–$30,000 |
| PVC/vinyl | $20–$35 | $50–$80 | $10,000–$16,000 | $20,000–$32,000 |
Maintenance Comparison
| Maintenance Task | Wood (Annual) | Composite (Annual) |
|---|---|---|
| Pressure washing | $150–$300 | $100–$200 |
| Sanding | $100–$200 (every 2–3 yrs) | Not needed |
| Staining/sealing | $300–$800 (every 2–3 yrs) | Not needed |
| Board replacement | $50–$200 (as needed) | Rare |
| Annual maintenance cost | $250–$550 | $50–$100 |
20-Year Total Cost of Ownership
| Pressure-Treated Wood | Composite (Mid-Range) | |
|---|---|---|
| Installation (400 sq ft) | $12,000 | $22,000 |
| Maintenance (20 years) | $7,000–$11,000 | $1,000–$2,000 |
| One replacement (year 15–18) | $8,000–$12,000 | Not needed |
| 20-year total | $27,000–$35,000 | $23,000–$24,000 |
Over 20 years, composite actually costs less because you avoid maintenance and replacement cycles.
Performance in Toronto's Climate
Freeze-Thaw Cycles
- Wood: Absorbs water, expands when frozen, contracts when dry. This cycle causes warping, splitting, and cupping over time.
- Composite: Does not absorb water (capped composites). Minimal dimensional change. Handles freeze-thaw well.
Summer Heat
- Wood: Stays relatively cool underfoot. Natural material does not retain heat.
- Composite: Gets HOT in direct sun. Dark colours can be uncomfortably warm. Light colours are better. Some premium brands have heat-reflective technology.
Snow and Ice
- Wood: Salt and calcium chloride are safe on wood. Shovel carefully to avoid gouging.
- Composite: Most are salt-safe, but check manufacturer guidelines. Easier to shovel (smoother surface).
UV/Fading
- Wood: Greys naturally without stain. UV degradation is cosmetic and addressed by regular staining.
- Composite: Modern capped composites resist fading well (25-year fade warranty common). Older or uncapped composites fade noticeably.
Appearance
| Factor | Wood | Composite |
|---|---|---|
| Natural look | Authentic grain, warm | Mimics wood (improved greatly, but still not identical) |
| Colour options | Unlimited (stain any colour) | 10–20 preset colours per brand |
| Consistency | Natural variation (knots, grain) | Uniform (some brands add variation) |
| Aging | Develops patina (or greys) | Stays consistent |
Popular Composite Brands in Toronto
| Brand | Price Range/ft | Warranty | Notes |
|---|---|---|---|
| Trex (Transcend) | $5–$8 | 25-year fade/stain | Most popular in GTA |
| TimberTech (AZEK) | $6–$10 | Lifetime limited | Premium PVC option |
| Fiberon | $4–$7 | 25-year stain/fade | Good mid-range |
| Deckorators | $4–$6 | 25-year structural | Budget composite |
| MoistureShield | $5–$8 | Lifetime limited | Excellent moisture resistance |
Which Should You Choose?
Choose wood if:- Budget is the primary constraint
- You enjoy annual deck maintenance (some people do)
- You want the most authentic natural look
- You plan to sell within 5 years (lower upfront cost, still looks great)
- You want minimal maintenance
- You are building your "forever" deck
- You can absorb the higher upfront cost
- You want consistent appearance for decades
