What Do You Know About Composite Decking?
Composite decking is a building material made from a mixture of wood fibers and recycled plastics. It combines the natural look of wood with the durability of synthetic materials. This composition offers excellent resistance to rot, insects, and weather damage, making it a popular alternative to traditional wood decks.

Why Focus on Composite Decking Cost Per Square Foot Canada?
When planning a deck, cost efficiency is key. The composite decking cost per square foot Canada gives you a baseline to estimate your total expenses based on the size of your deck. Unlike other cost metrics like linear foot or per board, pricing per square foot offers clarity for budgeting and comparisons.
Average Composite Decking Cost Per Square Foot in Canada
On average, the composite decking cost per square foot Canada ranges from CAD $10 to CAD $25. This wide range is influenced by several key factors such as brand reputation, board quality, design style, and local market conditions. Understanding these differences can help you select the right decking material that fits both your aesthetic preferences and budget.
Here’s a quick breakdown of typical price categories:
Cost Range (CAD) | Quality Level | Features |
---|---|---|
$10 – $15 | Entry-Level | Basic composite boards, limited color options, minimal texture or grain detail |

Warranty: Higher-priced boards often come with longer warranties, providing peace of mind regarding longevity and performance.
Aesthetic Variety: Premium composite decking offers more realistic wood grain patterns and richer colors, which may be worth the investment if curb appeal is a priority.

What Influences Composite Decking Price Per Square Foot in Canada?
Several factors impact the composite decking cost per square foot Canada. Understanding these can help you plan and avoid surprises.
1. Board Material and Quality
The quality of composite decking boards varies widely. Some boards use higher proportions of recycled plastic, better wood fiber blends, and superior UV stabilizers. Higher quality boards generally cost more but offer better longevity.
2. Brand and Manufacturer
Well-known brands like Trex, TimberTech, and AZEK often carry a premium price due to reputation and warranty offerings. Lesser-known or generic brands may offer lower costs but can vary in durability.
3. Board Style and Finish
Textured or grooved boards designed to mimic natural wood grain tend to cost more than smooth, flat boards. Some boards are capped with protective layers, which increase price but improve fade and scratch resistance.
4. Board Thickness and Width
Thicker and wider boards require more material and manufacturing effort, increasing the price per square foot.
5. Local Market and Supply
The availability of composite decking in your area and transportation costs can affect pricing. Remote or less populated regions may see slightly higher costs.
6. Seasonal Demand and Promotions
Demand tends to peak during spring and summer, potentially increasing prices. Conversely, off-season purchases or promotional sales may lower costs.
Installation Costs in Canada
When considering the composite decking cost per square foot Canada, it’s crucial to also factor in installation expenses, as they can significantly impact your overall budget.
DIY Installation:
Choosing to install the deck yourself can save you a substantial amount of money on labor costs. However, it requires a certain level of skill, experience, and the right tools to ensure a safe and quality build. Mistakes during installation can lead to costly repairs or reduce the deck’s lifespan, so DIY is best suited for those comfortable with carpentry work.
Professional Installation:
Hiring a professional contractor typically adds between CAD $8 to $15 per square foot, depending on the deck’s complexity, location, and labor rates in your area. Professional installers bring expertise, ensuring your deck meets all local building codes and standards. Additionally, many professionals offer warranties on their workmanship, which can provide peace of mind. Proper installation by experienced contractors also maximizes the lifespan and durability of your composite decking investment.
By weighing these options carefully, you can decide the best approach that fits your budget and skill level while ensuring a high-quality finished deck.

Additional Costs to Consider
Besides decking boards and installation, several other components contribute to the total project cost.
Substructure
The frame supporting the deck, usually made from pressure-treated wood or aluminum, can cost CAD $5 to $10 per square foot.
Fasteners and Hardware
Hidden fasteners and clips can add CAD $0.50 to $1 per square foot.
Railings and Accessories
Railings, stairs, and lighting vary widely but can easily add CAD $10 to $30 per linear foot.
Removal and Disposal of Old Decking
If replacing an old deck, removing debris can add CAD $1,000 or more depending on size and complexity.
