For most homeowners, pressure-treated wood is the more budget-friendly option upfront, while cedar offers a more natural look and tends to age with greater visual appeal. Both materials are commonly used for outdoor decks and perform well when properly installed and maintained.
The right choice depends on your budget, how much maintenance you are comfortable with, and how long you plan to stay in your home. In colder climates, including areas with heavy snow, ice, and freeze-thaw cycles, outdoor wood faces extra stress throughout the year. That makes durability and upkeep even more important than many homeowners expect.
In this comparison, we’ll break down cedar vs pressure-treated decks so you can choose the option that fits your home, your climate, and your long-term plans.
Cedar vs Pressure-Treated Decks: Quick Comparison
Review the head-to-head summary below before we examine each factor in detail.
| Factor | Cedar Decking | Pressure-Treated Decking |
| Installed cost (Ontario) | ~$55-80 per sq ft | ~$45-65 per sq ft |
| Typical lifespan | 15-20 years | 10-15 years |
| Maintenance | Clean and reseal every 1-2 years | Clean and seal every 2-3 years |
| Look | Warm, natural, reddish-brown | Greenish or brown, more uniform |
| Rot resistance | Natural cedar oils | Added chemical preservatives |
| Best for | Looks and comfort | Budget and strength |
What is Cedar Decking?
Cedar decking is a natural softwood, usually Western Red Cedar, prized for its appearance and built-in rot resistance. It survives outdoors without any chemical treatment, because the wood protects itself. For that reason, many homeowners choose cedar and other softwood decking for a natural finish.
So how does that protection actually work? Cedar heartwood contains natural compounds called thujaplicins, which act as a built-in fungicide and fight the fungi that cause rot.
According to the Government of Canada’s naturally:wood resource, fallen cedar trees can stay sound for over 100 years thanks to this resistance. That natural durability is exactly why cedar performs so well as a deck surface.
What Is Pressure-Treated Wood?
Pressure-treated wood is softwood, often pine or spruce, infused with preservatives to resist rot, insects, and decay. It remains the most affordable and most common deck material across our region. Builders also rely on it for pressure-treated framing and full deck builds.
Here is how the treatment process works. The lumber enters a sealed chamber, and then preservatives get forced deep into the wood fibres under pressure. Today’s boards use copper-based formulas like ACQ rather than the old arsenic mix. In fact, the US EPA confirms ACQ is now the most widely used residential wood preservative. Once the wood dries, the surface accepts stain or paint readily.

Cedar vs Pressure-Treated Decks: Head-to-Head Comparison
Now let’s break down the real differences. We install both woods every season, so these observations come from hands-on experience, not theory. Below, you’ll see how cedar and pressure-treated decking compare across the factors that matter most to homeowners.
1. Cost and Budget Differences
Cedar decking runs higher upfront, at roughly $55-80 per square foot installed in Ontario. In return, that premium buys natural looks and a longer service life. As a result, many homeowners consider the trade worthwhile.
On the other hand, pressure-treated decking is the budget choice, landing around $45-65 per square foot installed. On a large deck, that gap adds up quickly. So for cost-conscious projects, treated wood clearly comes out ahead on price.
2. Durability and Lifespan Outdoors
Cedar decks last about 15-20 years with proper care. The wood resists warping and holds its shape, and its low density helps it shrug off our wet springs. With consistent upkeep, that lifespan stretches even further.
Pressure-treated decks, by comparison, usually last 10-15 years for the boards. Here is a fact many homeowners miss: modern treated lumber does not last as long as the older arsenic-based wood did. As a result, owners often replace boards sooner than they planned. When that happens, deck removal and rebuilding becomes the practical fix. Ground-contact-rated boards and proper detailing help delay that day.

3. Resistance to Rot, Insects, and Moisture
Cedar fights rot on its own. Its natural oils repel decay fungi and many insects, including termites and ants, so no added chemicals are needed. Even so, cedar struggles in shaded, slow-drying spots that stay damp for long stretches.
Pressure-treated wood, by contrast, draws its protection from added chemicals. The preservatives guard against rot, fungal decay, and insect damage, which makes it the smarter choice for ground-level decks. It also tolerates direct soil contact far better than cedar does.
4. Appearance and Natural Aesthetic
Cedar wins on looks for most people. It displays a warm, reddish-brown tone with clean, straight grain. On top of that, it carries a pleasant aroma and stays cool underfoot on hot days, so homeowners especially value that barefoot comfort.
Pressure-treated wood looks plainer by comparison. New boards carry a greenish or brown tint and a more uniform face. You can stain it any colour once it dries, though it rarely matches cedar’s natural richness.
5. Maintenance and Upkeep Requirements
Cedar asks for steady attention. Plan to clean and reseal it every one to two years, because if you skip that step, the wood fades to a silvery grey. Many homeowners find this staining cycle tiring, so professional deck design, installation, and finishing often makes the long-term upkeep easier to manage.
Pressure-treated wood proves more forgiving early on, since a clean and seal every two to three years keeps it solid. Still, it cracks, warps, and greys without care. In the end, both woods reward a consistent sealing schedule.
6. Ease of Installation and Workability
Cedar is light and easy to cut, nail, and shape, and its stability keeps the boards lying flat and straight. That said, cedar is a soft wood, so chair legs and dropped tools can dent the surface.
Pressure-treated wood is heavier and stronger. It carries structural loads well, which is why we rely on it for ground-level deck framing and footings. However, wet boards can twist as they dry, and they also require corrosion-rated fasteners to hold securely.
7. Environmental Impact and Sustainability
Cedar is the greener wood. It is natural, renewable, and biodegradable at the end of its life. For the best footprint, choose boards from responsibly managed or FSC-certified forests, and rest easy knowing no harsh chemicals leach into your yard.
Pressure-treated wood, on the other hand, raises more environmental questions, since the copper preservatives can migrate into soil over time. You should also never burn the offcuts, because the smoke is toxic. Instead, dispose of scraps through proper channels rather than a backyard fire.

Regardless of which you choose, the quality of the build determines how long it lasts, and that is precisely where local experience pays off. Book a free consultation with our deck-building team in Newmarket, and let’s plan a deck made for our climate.
Frequently Asked Questions
Is cedar worth the extra money over pressure-treated wood?
For many homeowners, yes. Cedar lasts longer and looks better, which often justifies the higher cost over time.
Does a cedar deck have to be stained?
No, cedar can grey naturally without any harm to the wood. Staining is optional, but it keeps the warm colour and slows weathering.
Is modern pressure-treated wood safe for families and pets?
Yes. Today’s ACQ-treated wood contains no arsenic. Health Canada confirms CCA was removed from residential use in 2004.
Which lasts longer outdoors, cedar or pressure-treated wood?
Cedar usually lasts longer for deck boards. With good care, it can outlive treated boards by several years.
Can I mix both woods on one deck?
Yes, and many builders do. Treated wood works best for the frame, while cedar shines as the visible deck surface.
