Thinking about adding a deck to your home? Great choice! A deck is the perfect place to host summer BBQs, enjoy your morning coffee, or just relax after a long day. But before you break out the measuring tape, you’re probably wondering: how much does it actually cost to build a composite deck in Southwestern Ontario?
We’ve got you covered. At The Deck Master, we believe in transparency, so let’s break down the costs of composite decking, from materials to installation.
The Basics: What Affects Composite Decking Costs?
Composite decking is a fantastic investment; it’s durable, has low maintenance, and looks amazing. But like any home improvement project, the cost depends on several factors:
Deck Size: Bigger decks need more materials, which means a higher overall cost.
Material Quality: Premium composite boards(like Trex or TimberTech) can cost more but offer superior longevity
Substructure & Framing: The foundation of your deck is just as important as the surface. Pressure-treated lumber is often used, but steel framing is another option (at a higher price point).
Additional Features: Built-in seating, railing, lighting, and stairs can increase the total price.
Labor Costs: In Southwestern Ontario, labour costs can account for about 60-70% of your total decking projects.

Remember, these prices are just estimates! The final price can vary based on the brand of composite decking you choose and local supply costs.
Composite vs. Wood: Is It Worth the Extra Cost?
You might be wondering, why should I choose composite decking over traditional wood? While wood may have a lower upfront cost, composite decking offers long-term savings.
Low Maintenance- No Staining, sealing or sanding. Just occasional cleaning!
Longevity- Composite decks last 25+ years, while wood decks require frequent upkeep and replacement.
Eco-Friendly- Many composite brands use recycled materials, making it a sustainable choice.
Resistant to the Elements- Southwestern Ontario sees its fair share of harsh winters and humid summers, a Composite deck won’t warp, crack, or rot like wood.

Tips to Stay on Budget
Plan Your Design Wisely – Simpler designs cost less. Curved decks, built-in seating, and multi-level structures increase labor and material costs.
Choose Mid-Range Composite Boards – High-end brands are great, but mid-tier options still offer durability at a lower cost.
Get Multiple Quotes – Always compare prices from different contractors to find the best deal.
Build Off-Season – Late fall and early winter often have lower labor costs as demand for contractors slows down.
Final Thoughts: Is Composite Decking Right for You?
If you’re looking for a deck that’s beautiful, long-lasting, and hassle-free, composite decking is a fantastic option. While the upfront costs might be higher than wood, the long-term benefits—low maintenance, durability, and eco-friendliness—make it a worthwhile investment.
