How much does Kebony modified wood decking cost installed in Calgary compared to western red cedar?

Kebony modified wood decking costs $45-65 per square foot installed in Calgary, compared to $35-55 per square foot for western red cedar — making Kebony roughly 25-40% more expensive upfront but potentially more cost-effective over the deck's lifetime due to dramatically reduced maintenance requirements.

Kebony is thermally modified softwood (typically pine or maple) that's been heated to 200+ degrees Celsius to fundamentally alter the wood's cellular structure. This process makes the wood extremely stable, rot-resistant, and dimensionally stable — addressing many of the challenges that plague traditional wood decking in Calgary's extreme climate. The modification process removes the sugars that feed rot and mould, while creating a wood that's naturally resistant to moisture absorption and insect damage.

For Calgary's challenging climate conditions, Kebony offers significant advantages over cedar. While western red cedar naturally contains extractives that resist rot, it's still a relatively soft wood that dents easily, checks and splits in Calgary's dry air, and requires staining every 1-2 years to maintain UV protection at our 1,045-metre elevation. Kebony's thermal modification makes it much harder and more stable than cedar, with minimal shrinkage, swelling, or checking even through Calgary's notorious chinook freeze-thaw cycles. The modified wood also handles UV exposure better than untreated cedar, silvering more slowly and evenly.

The maintenance difference is where Kebony's value proposition becomes compelling. Cedar decking in Calgary requires annual cleaning and staining/oiling every 1-2 years to prevent UV damage, moisture penetration, and premature aging. Professional restaining costs $3-8 per square foot every other year. Over a 20-year period, cedar maintenance costs can easily reach $30-60 per square foot. Kebony can be left to weather naturally to an attractive silver-grey patina, or maintained with periodic oiling (every 3-5 years) if you prefer to retain the original honey-brown colour. This dramatically reduces lifetime maintenance costs and labour.

Installation costs are similar between Kebony and cedar since both use standard deck fasteners and installation techniques. However, Kebony's superior dimensional stability means fewer callbacks for warped or twisted boards, and the pre-drilling requirements are less stringent than with dense hardwoods like ipe. The material itself accounts for most of the cost difference — Kebony typically runs $12-18 per square foot for materials versus $6-12 for western red cedar.

For a typical 300-square-foot deck, expect to pay $13,500-$19,500 for Kebony versus $10,500-$16,500 for cedar. While that's $3,000-$4,000 more upfront, the reduced maintenance requirements often justify the premium for homeowners who want the beauty of natural wood without the ongoing commitment of annual staining. Kebony also carries a 30-year warranty against rot and decay, compared to cedar's typical 15-25 year lifespan with proper maintenance.

The main considerations with Kebony are availability and colour options. Not all Calgary lumber yards stock Kebony regularly, so lead times can be longer than cedar. The thermal modification process also limits colour variation — you get a consistent honey-brown that weathers to silver-grey, whereas cedar offers more natural colour variation and grain patterns.
