Cedar costs less upfront ($55-$85/sq ft installed vs $90-$140 for composite) but needs annual washing and stain every 2 years, lasting 12-18 years in Vancouver. Composite costs 50-70% more upfront, requires zero maintenance, and lasts 30-40 years with a 25-50 year warranty. Over 20 years, composite is cheaper. Cedar wins on look, smell, and budget; composite wins on lifecycle cost and Vancouver climate fit.
It’s the most common question we get on a deck site visit: “Cedar or composite?”
There’s no universally right answer — but for Metro Vancouver specifically, the math has shifted hard in the last five years. Better composite products, longer warranties, and our particular climate make this a different decision than it would be in Calgary or Toronto.
This is the comparison without the marketing. We install both. We have no preference for either material — we just want you to make the call with your eyes open.
Quick Verdict by Use Case
| If You Are… | Pick… |
|---|---|
| Selling within 5 years | Cedar (lower upfront, fine for short-term) |
| Staying 10+ years | Composite (cheaper over time) |
| Have kids, pets, or bare-foot summers | Composite (no splinters, no slivers) |
| Refuse to stain/seal/sand annually | Composite (zero maintenance) |
| Love the smell and warmth of real wood | Cedar (no contest) |
| Building a heritage-style or traditional home | Cedar (aesthetic match) |
| Modern home, glass railings, clean lines | Composite (designed for it) |
| Tight budget, single-level deck under 200 sq ft | Cedar (saves $5,000-$10,000 upfront) |
The Real Installed Cost (Metro Vancouver, 2026)
Sticker shock comparison. Both numbers below are turnkey — substructure, fasteners, picture-frame border, standard railings included.
| Material | Per sq ft (installed) | 300 sq ft deck | 500 sq ft deck |
|---|---|---|---|
| Pressure-treated pine | $35-$55 | $10,500 - $16,500 | $17,500 - $27,500 |
| Western Red Cedar | $55-$85 | $16,500 - $25,500 | $27,500 - $42,500 |
| Capped composite (Trex / Fiberon) | $90-$120 | $27,000 - $36,000 | $45,000 - $60,000 |
| Premium PVC (TimberTech AZEK) | $110-$140 | $33,000 - $42,000 | $55,000 - $70,000 |
So composite typically costs 50–70% more upfront than cedar of equivalent size. That’s the headline. Now let’s look at what happens after year one.
20-Year Total Cost of Ownership
This is where the comparison gets uncomfortable for cedar. We’re modeling a 300 sq ft deck in Metro Vancouver over 20 years.
| Cost Item | Cedar | Composite |
|---|---|---|
| Initial install | $21,000 | $31,500 |
| Annual cleaning ($300/yr × 20) | $6,000 | $0 (hose-off) |
| Re-stain/seal every 2 years ($1,200 × 10) | $12,000 | $0 |
| Replace 10-15% of boards (yr 8-12) | $2,500 | $0 (warranty) |
| Full deck replacement at year 15-18 | $24,000+ (re-build) | $0 (still under warranty) |
| 20-Year Total | ~$65,500 | ~$31,500 |
Composite costs roughly half of cedar over 20 years in Vancouver. The variables that change this math:
- If you DIY the staining and cleaning, cedar drops to ~$40,000 over 20 years (still more)
- If you skip maintenance entirely, cedar’s lifespan drops to 8-10 years (full replacement bumps total well above $70,000)
- If you sell within 5-7 years, the math flips because you don’t pay the year-15 replacement
Why Vancouver’s Climate Punishes Cedar
This is the part most material comparisons skip. The Pacific Northwest is one of the worst climates in North America for wood decks:
Rainfall. Metro Vancouver gets 60+ inches of rain a year. Wood absorbs water, swells, contracts when it dries, and develops surface checks. Composite is impervious.
Freeze-thaw cycles. We get 30-40 freeze-thaw cycles per winter. Every cycle creates microscopic cracks in stained wood. Stain breaks down. Five years in, every cedar deck looks tired.
Mold and moss. Walk any Vancouver neighbourhood in February — every cedar deck has moss patches and dark mold lines along the joist edges. Wood is porous; spores root into it. Capped composite has a non-porous polymer shell that nothing can grow in.
UV. Even our cloudy summers fade unstained cedar to grey within 6 months. UV-resistant stains help but break down in 12-18 months in our sun cycles.
Ground contact. Cedar in contact with damp BC soil rots from the bottom up. We always elevate decks on engineered footings, but the lower joists still see consistent moisture.
In drier climates (Phoenix, Denver), cedar can last 25-30 years with reasonable maintenance. In Vancouver, realistic cedar lifespan is 12-18 years with proper care, 8-10 years if you slack on maintenance.
Composite Has Two Real Downsides
We’re not pretending composite is perfect. Two honest weaknesses:
1. Heat in direct sun
Composite runs 10-25°F warmer than cedar on a hot day. The polymer cap absorbs more solar radiation than wood. Color matters a lot: light greys and tans are tolerable; dark espresso and black get genuinely uncomfortable barefoot in July afternoon sun. Vancouver only gets 50ish truly hot days a year, but if your deck faces full west and you have kids running on it, factor this in.
Mitigations:
- Pick lighter colors (we have 4-6 cool-touch options)
- Use TimberTech AZEK (PVC, ~5°F cooler than wood-fiber composites)
- Add a pergola, umbrella, or shade sail
2. Initial cost shock
There’s no way around it — composite is a bigger upfront line item. If you don’t have the cash flow or financing for the 50-70% premium, cedar is the right call. The lifecycle math favors composite, but only if you’re staying in the home long enough to realize the savings.
Cedar Has Two Real Strengths
Symmetrically:
1. The look and the smell
Real cedar has a warmth, grain variation, and aroma that composite doesn’t replicate. The closest is TimberTech Vintage Collection or Trex Lineage — they’re stunning, but they’re not real wood. If you walk on real cedar boards every morning and that matters to you, that matters.
2. Repair and modify cost
A cedar deck is easy to repair. Replace one board, sand it, stain it. Composite is also repairable, but matching color across a board manufactured 8 years ago is harder — UV fades the originals, the new board is brighter, and the patch is visible. For decks in high-impact areas (kids’ play zones, dog runs), this matters.
Brand Recommendations (If You Go Composite)
We’re brand-agnostic and carry all four major manufacturers. Our recommendations:
- Trex — best ESG story (95% recycled material), longest track record (since 1996), widest color range. Pick if sustainability matters or you want maximum color choice.
- TimberTech AZEK — pure PVC, runs cooler underfoot, most realistic wood grain. Pick if sun exposure is high or you want a wood-like aesthetic without wood.
- Fiberon — best price-to-performance, especially Concordia line. Pick if budget is tight but you still want capped composite.
- Deckorators Voyage — capped polymer, lightest in weight, premium-feel surface. Pick if you want a specific high-end look and don’t mind paying for it.
Bottom Line for Metro Vancouver
Choose cedar if you’re flipping in 3-5 years, building traditional/heritage style, or genuinely love wood and don’t mind annual maintenance.
Choose composite if you’re staying long-term, hate maintenance, have kids or pets, or want a deck that still looks new at year 15.
For our typical Vancouver client — a homeowner planning to stay 10+ years in a modern or transitional home — composite is the right call about 75% of the time. The 20-year math is hard to argue with.
