The Case for Composite Decking: Is It Worth the Extra Cost in Toronto?

Composite decking costs roughly three to four times what pressure treated lumber costs per square foot of installed deck. That’s a real and significant difference, and for most homeowners it’s the number that ends the conversation before it starts. But the upfront cost comparison isn’t the right comparison – and when you do the right comparison, the math is more interesting.

What Composite Decking Actually Is

Composite decking is made from a combination of wood fibre and recycled plastic, typically with a protective polymer cap on the surface. The most recognized brand is Trex; there are several others. The core doesn’t absorb water, doesn’t rot, doesn’t support mould growth, and doesn’t provide anything for insects to eat. The cap protects against UV fading and surface staining.

It is not maintenance-free – it should be cleaned periodically, and the fasteners and frame beneath it are still subject to normal wear. But it doesn’t need staining, sealing, sanding, or refinishing. Ever.

What Pressure Treated Needs

A pressure treated deck in Toronto looks great when it’s new. Within a season or two, untreated, it begins to grey. Within three to five years, if it hasn’t been stained and sealed, it starts to check (surface cracking) and splinter.

Maintaining a pressure treated deck properly means:

• Cleaning and sanding every 2 to 3 years
• Applying a penetrating stain or semi-transparent finish every 2 to 3 years
• Checking for and replacing boards that have split or badly checked

The cost of this maintenance over a 25-year deck lifespan – materials and labour – typically runs $3,000 to $8,000 depending on the deck size. That’s not nothing.

The 25-Year Cost Comparison

On a typical 200 square foot Toronto deck:

• Pressure treated: $8,000–$12,000 installed + $4,000–$8,000 maintenance = $12,000–$20,000 over 25 years
• Composite (Trex or equivalent): $24,000–$32,000 installed + $500–$1,000 maintenance = $24,500–$33,000 over 25 years

On a straight cost basis over 25 years, composite is still more expensive. But it’s not three to four times more expensive when you include maintenance – it’s 20 to 60 percent more expensive, depending on how diligently the pressure treated deck is maintained.

The Non-Cost Factors

The numbers above don’t capture:

• Composite doesn’t splinter – relevant if you have children or go barefoot on the deck
• Composite doesn’t grey, check, or look shabby between maintenance cycles – relevant if curb appeal matters to you
• Composite doesn’t require you to think about it, plan around it, or spend a weekend every two years maintaining it – relevant if your time has value
• Composite holds its appearance for longer when maintained – relevant if you’re staying in the home long-term

Who Should Choose Composite

Composite makes the most sense for homeowners who plan to stay in the home long-term, have children or use the deck barefoot regularly, place high value on a consistently good-looking outdoor space, and don’t want to add deck maintenance to their annual task list.

Who Should Choose Pressure Treated

Pressure treated makes the most sense for homeowners with a tighter budget who are willing to do (or pay for) maintenance, those who may not be in the home for 20+ years, or those whose primary goal is a functional deck at the lowest possible upfront cost.

Both are good choices, made well. The mistake is choosing composite and not maintaining it, or choosing pressure treated and then not maintaining it. Talk to us at the quote stage and we’ll give you an honest picture of both.
