This is one of the most common questions we get, and the honest answer is: both work.
The real question is which one works better for you.
Pressure-Treated Wood
Pressure-treated (PT) wood is softwood — usually pine or fir — that's been treated with preservatives to resist rot and insects.
It's the most popular deck material in Quebec, and for good reason.
What's good about it
- Lower upfront cost — typically 30–50% cheaper than cedar per square foot
- Widely available — easy to source, consistent quality across suppliers
- Durable — handles Quebec winters well when properly maintained
- Easy to paint or stain — takes coatings more predictably than cedar
What to watch for
- Arrives wet from the treatment process and needs time to dry before staining
- Can warp slightly as it dries, especially in wider boards
- Has a greenish tint when new that fades, but the wood still needs periodic sealing
Maintenance reality
Seal or stain PT wood every 2–3 years to keep it looking good. Skip this and it grays out and starts to split.
It's not high-maintenance — but it's not zero maintenance either.
Cedar
Cedar is a naturally rot-resistant wood with a warm, reddish-brown tone. It's been used for decks in Quebec for generations.
What's good about it
- Beautiful grain — the natural look is hard to match with any other material
- Naturally rot and insect resistant — fewer chemicals, no treatment odor
- Dimensionally stable — less warping and shrinking than pressure-treated
- Better splinter resistance — smoother feel underfoot over time
What to watch for
- Costs more upfront — the premium is real
- Still needs periodic sealing or staining to maintain its look
- More variable in quality — knots and grain differ from board to board
Maintenance reality
Cedar is sometimes sold as "low maintenance" — but that's not quite accurate. Left untreated, it grays beautifully but will eventually weather, crack, and degrade.
Seal or stain every 2–3 years, same as pressure-treated.
What Most Quebec Homeowners Choose
For most projects under 300 sq ft, pressure-treated makes more financial sense.
The price difference is real. On a 12x16 deck, PT vs cedar might be a $1,500–$3,000 difference in materials alone — before labor.
Cedar tends to make more sense when:
- Aesthetics are the priority and the natural look matters
- The deck is visible from the street or a main entertaining area
- Budget allows for the premium and you want to invest in it
The Bottom Line
| Pressure-Treated | Cedar | |
|---|---|---|
| Upfront cost | Lower | Higher |
| Look | Utilitarian, takes stain well | Warm, natural grain |
| Durability | Very good | Very good |
| Maintenance | Every 2–3 years | Every 2–3 years |
| Best for | Most homeowners | Premium builds |
Both materials can give you a deck that lasts 20–30 years with proper care.
The best material is the one that fits your budget, your aesthetic, and your maintenance comfort level. If you're unsure, pressure-treated is almost always the right default. You can always upgrade on a future project once you know what you want.
