Composite vs Wood Deck Toronto— Costs, Maintenance, Lifespan

# Composite vs Wood Deck Toronto — Costs, Maintenance, Lifespan Compared

Quick answer. \n*Part of our Exterior Home Maintenance Guide Toronto.*\n

The biggest decision when building a deck in Toronto is the material. Wood is cheaper upfront. Composite costs more initially but saves on maintenance. Which one actually costs less over the life of the deck? This guide runs the numbers.

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

Note: Substructure (posts, beams, joists) is pressure-treated wood regardless of decking material — this is code requirement and best practice.

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)

Choose composite if:

You want minimal maintenance
You are building your "forever" deck
You can absorb the higher upfront cost
You want consistent appearance for decades
