Choosing the Right Wood for Your Deck: Cedar vs. Pressure-Treated Lumber
Building a backyard deck is one of the best ways to enhance your home’s outdoor space—but before the first board is cut, you’ll need to make an important decision: what type of wood should you use?
In Canada, cedar and pressure-treated wood are two of the most widely used materials for residential decks. Each has its pros and cons when it comes to durability, cost, maintenance, and aesthetics. Knowing how they compare can help you make the right call for your home and lifestyle.
If you’re thinking of installing a custom deck in Toronto or the Greater Toronto Area, this guide will walk you through the key differences between cedar and pressure-treated wood—and how to choose the best fit for your project.
Pressure-Treated Wood: Tough, Affordable, and Versatile
Pressure-treated wood is a common sight in Canadian backyards, and for good reason. It’s typically made from pine that’s infused with chemical preservatives under high pressure. This process helps the wood resist moisture, rot, insects, and general outdoor wear and tear.
Key Advantages:
Built to Last: Treated to withstand Canadian weather, including snow, rain, and temperature swings. A great long-term solution for foundational support and framing.
Budget-Friendly: One of the most affordable deck wood options on the market, offering great value for homeowners looking to balance quality and cost.
Multipurpose Use: Can be used for nearly every part of a deck, including framing, joists, posts, and even surface boards, making it a flexible option for structural and visible elements.
Things to Consider:
Ongoing Maintenance: Treated lumber requires regular upkeep—staining, sealing, or washing—to keep it looking good and performing well.
Fading Over Time: The colour may fade more quickly than other woods, and weathering can cause it to lose its original appearance unless maintained.
Rough Texture: Pressure-treated wood is known to splinter as it ages, which might make it less ideal for areas where people walk barefoot or sit.
Cedar Wood: Naturally Beautiful and Low-Maintenance
If you’re looking for something with natural charm and excellent resistance to the elements, cedar decking may be the way to go. This softwood doesn’t need chemical treatment to hold up against rot and pests—its natural oils do the work.
What Makes Cedar Great:
Organic Durability: Cedar contains compounds that act as a natural defense against insects, fungi, and moisture, making it ideal for deck surfaces and railings.
Visual Appeal: With its warm hues and smooth grain, cedar is a go-to choice for homeowners who want a deck that looks polished and refined.
Stable Under Stress: Cedar handles moisture better than many woods, expanding and contracting less in fluctuating temperatures. This helps reduce warping or cracking.
Potential Drawbacks:
Higher Price Tag: Cedar typically costs more than pressure-treated wood, which can influence the overall budget.
Limited Size Options: Certain board sizes or cuts may not be as readily available, requiring custom orders or special arrangements with suppliers.
Which Wood Should You Use for Your Deck?
There's no one-size-fits-all answer, but here’s how we often guide homeowners in Toronto and the GTA:
For structure and affordability, pressure-treated wood is an excellent choice, especially for framing, posts, or parts of the deck that aren’t in full view.
For visible surfaces, cedar adds a touch of natural luxury and charm with less ongoing maintenance.
Many homeowners end up combining both materials for a balanced approach: pressure-treated wood for the frame, and cedar for the surface, stairs, or railing. This hybrid method gives you strength, beauty, and cost-efficiency in one custom solution.
