Two of BC’s most popular decking materials — and the choice between them can affect your budget, your maintenance schedule, and the look of your outdoor space for the next 20+ years. Here’s an honest comparison of cedar vs. pressure treated decking for Vancouver homeowners.
What Is Cedar Decking?
Western Red Cedar is a softwood native to the Pacific Northwest. It’s been the go-to decking material in BC for decades — and for good reason. Cedar naturally produces oils that repel moisture, insects, and decay without chemical treatment. The warm honey tones and visible grain make it one of the most beautiful decking options available.
At VS Deck & Rail, we use kiln-dried, clear-grade Western Red Cedar for decking surfaces, with pressure-treated lumber for all structural components (posts, joists, beams).
What Is Pressure Treated Decking?
Pressure treated (PT) lumber is standard wood — typically hem-fir or spruce-pine-fir — that’s been injected with preservatives under pressure to resist rot, insects, and moisture. The treatment gives it a greenish tint that fades to grey-brown over time.
Modern PT wood uses ACQ (Alkaline Copper Quaternary) or MCA treatment — both are considered safe for residential use, including for raised garden beds and children’s play areas.
Cedar vs. Pressure Treated: Side-by-Side Comparison
| Cedar | Pressure Treated | |
|---|---|---|
| Cost (installed) | $45–$70/sq ft | $35–$55/sq ft |
| Lifespan | 20–30 years (with maintenance) | 15–25 years |
| Appearance | Warm honey/amber, natural grain | Greenish when new, weathers grey |
| Maintenance | Seal/stain every 1–2 years | Seal every 2–3 years |
| Splinter risk | Low (smooth when kiln-dried) | Moderate (can check as it dries) |
| Eco-friendliness | Naturally treated, no chemicals | Chemical preservatives required |
| Stainability | Excellent — accepts any stain | Good — must be fully dry first |
| Best for | Aesthetics, natural look | Budget builds, structural framing |
Cedar Decking: Pros and Cons
Pros
- Naturally rot and insect resistant — no chemical treatment needed on deck surface
- Beautiful appearance — warm, natural, classic West Coast aesthetic
- Accepts stains and finishes — customize the colour easily
- Lightweight — easier on deck framing and substructure
- Comfortable underfoot — stays cooler than composite on hot days
Cons
- Higher cost than pressure treated
- Requires sealing every 1–2 years to maintain colour and protection
- Can grey quickly if left unsealed — though many homeowners prefer the silver patina
Pressure Treated Decking: Pros and Cons
Pros
- Most affordable decking material
- Strong and stable — handles structural loads well
- Widely available — faster lead times
- Long lifespan when properly maintained
Cons
- Greenish tint when new — needs time or staining to look natural
- Can warp and check as it dries out — especially in the first season
- Less appealing appearance compared to cedar or composite
- Must dry before staining — typically 6–12 months after installation
Which Is Better for Vancouver’s Climate?
Both materials can handle BC’s wet winters well — but they require different care.
Cedar is uniquely adapted to the Pacific Northwest. Its natural oils make it inherently resistant to the moisture cycle of wet winters and dry summers. A properly sealed cedar deck in Vancouver will look beautiful for decades.
Pressure treated wood holds up structurally, but the surface boards can check (develop small cracks) as they dry. This is normal and cosmetic — it doesn’t affect structural integrity — but some homeowners find it unsightly.
For the substructure (joists, beams, posts), we use pressure treated lumber on every build regardless of the surface material. PT is simply better suited for ground-contact and structural applications.
Cost Comparison: Cedar vs. Pressure Treated in Metro Vancouver
For a 300 sq ft deck in Metro Vancouver (excluding railings) — see our full Vancouver deck cost guide for a detailed breakdown:
- Pressure treated deck: $10,500–$16,500
- Cedar deck: $13,500–$21,000
The cedar premium is typically $3,000–$6,000 on a standard residential deck — and most homeowners who go cedar say it was worth it for the look and feel.

Frequently Asked Questions
Which lasts longer — cedar or pressure treated decking?
Cedar typically lasts 20–30 years with regular sealing. Pressure treated decking lasts 15–25 years. Both lifespans assume proper maintenance and a quality substructure.
Is pressure treated wood safe for Vancouver homes?
Yes. Modern PT wood uses ACQ or MCA treatment, which is considered safe for residential use by Health Canada. It’s suitable for decks, playgrounds, and garden structures.
Can I stain pressure treated wood right away?
No — pressure treated lumber needs to fully dry before accepting a stain, typically 6–12 months after installation. A water-repellent sealer can be applied sooner.
Should I choose cedar or PT for a covered deck?
If the deck is fully covered (like an inground pool deck or a deck under a roof), pressure treated is a great value — it gets less UV and moisture exposure, so the appearance disadvantage matters less. For an open deck where aesthetics count, cedar is the better choice.
