Understanding the cost of a deck is crucial when planning your perfect outdoor space. From material choices to deck dimensions, each decision impacts the final price. So, how much does a deck cost per square footage? What should you consider when estimating the total cost of your deck project? In this article, we will break down the costs of different deck designs, materials, and sizes to help you make an informed choice for your budget and vision.
How Much Does a Deck Cost per Square Foot?
The deck cost per sq ft will vary and depend on your chosen materials, labour costs, and regional pricing. The average cost of a deck in Canada is between $30 and $100 per square foot, including materials and labour. Here is a very brief breakdown by material:
- Pressure-treated wood: $29–$55 per square foot.
- Cedar or Redwood: $39–$60 per square foot.
- Composite decking: $63–$92 per square foot.
- Concrete deck: $50–$100 per square foot.
These figures provide a rough estimate, but your actual deck cost per sq ft may vary based on location and complexity.
How Does the Choice of Material Impact the Final Price Point?
The material you choose greatly influences your deck’s overall cost. Some materials are affordable upfront but require ongoing maintenance, while others have higher initial costs but save money long-term. For ease of reference, here is a comparative chart of popular decking materials and what they typically cost:
| Material | Cost per square foot (includes deck surface materials, basic hardware and average labour costs) | Pros | Cons |
| Pressure-Treated Wood | $29–$55 | Affordable upfront; widely available; resistant to rot and insects (treated). | Requires regular maintenance (staining/sealing); less durable long-term. |
| Cedar or Redwood | $39–$60 | Naturally resistant to rot and insects; cooler underfoot; beautiful natural appearance. | Higher upfront cost; requires regular maintenance to prevent weathering. |
| Composite Decking | $63–$92 | Low maintenance; durable; resistant to rot, insects, and fading; long lifespan. | Higher upfront cost; can get hot underfoot; lacks authentic wood texture. |
| Concrete | $50–$100 | Highly durable; weather-resistant; low maintenance; customizable with stains or patterns. | Higher upfront cost; lacks the warmth of wood; requires periodic resealing. |
Material-Specific Cost Breakdowns
While the chart provides an overview, each material has unique costs and considerations. Below are detailed average deck cost estimates for different materials and deck sizes. The charts are for the deck platforms only and do not include stairs or railings. The end of this section will provide more information about those.
Pressure-Treated Wood: Affordable and Reliable for Outdoor Living

Additional Elements
To the costs mentioned above, you must also add the cost of railings and stairs.
- Wood railings: $30 to $80 per linear foot
- Aluminum railings: $50 to $150 per linear foot
- Glass railings: $65 to $250 per linear foot
- Deck stairs: $100 to $500 per step, depending on the material and complexity of the staircase
As previously mentioned, these costs are estimates and can vary significantly depending on the nature of the project. For an exact cost estimate, always consult an expert.
What Should I Keep In Mind When Budgeting for My Dream Deck?
When planning your deck, consider these key factors to ensure your project aligns with your vision and budget:
- Materials: The choice of materials impacts the upfront cost and long-term expenses. Pressure-treated wood is the most affordable but requires regular attention, while composite decking materials and aluminum have higher initial costs. However, they save money over time with minimal upkeep.
- Railings: Railings can significantly affect costs, with wood costing $30–$80 per linear foot and glass costing around $65 per linear foot. Durable options like aluminum cost about $50 per linear foot and may increase labour expenses for intricate designs.
- Size and Features: Larger or multi-level decks require more materials and labour, raising costs. Depending on the complexity and materials used, additional features like roofs, stairs, or lighting can add between $500 and $10,000.
Consider how materials, railings, labour, and features work together to budget accurately. A simple deck with basic wood railings will cost far less than a multi-tiered design with aluminum railings and custom lighting. Prioritize your needs and find the balance that fits your lifestyle and budget.
What Type of Deck Will Give Me the Most Value for My Money?
When considering long-term value, composite decking stands out as a top contender. While composite decking cost per square foot in Canada ranges from $63 to $92, installation included, it offers significant savings over time due to its durability and minimal upkeep requirements. Resistant to rot, insects, and fading, composite decks eliminate the need for regular staining, sealing, or frequent repairs, making them an excellent investment for homeowners seeking long-lasting quality.
For those who value natural aesthetics and are willing to commit to some maintenance, cedar decks provide a strong balance of affordability and longevity. The cost of a wood deck per sq ft is between $39 and $60 for cedar wood, installation included. Cedar’s natural resistance to rot and insects minimizes upkeep compared to pressure-treated wood, while its timeless beauty can add to your home’s curb appeal.
Ultimately, the deck material that provides the most value will align with your specific priorities. Each option elevates your outdoor space while delivering a return on investment aligned with your unique needs.
