How much more does a Western Red Cedar deck cost compared to pressure-treated spruce in Calgary right now?

A Western Red Cedar deck typically costs 30-50% more than pressure-treated spruce in Calgary, with cedar running $35-55 per square foot installed versus $25-45 for pressure-treated lumber.

The material cost difference drives most of this premium. Cedar decking boards cost $6-12 per square foot for materials alone, while pressure-treated spruce runs $3-6 per square foot. On a typical 300-square-foot deck, you're looking at $10,500-$16,500 for cedar versus $7,500-$13,500 for pressure-treated — a difference of roughly $3,000-$5,000.

Labour costs remain similar between the two materials since both require the same substructure, footing work, and installation techniques. The price gap comes entirely from the cedar boards themselves, which cost significantly more due to Western Red Cedar's natural rot resistance, attractive grain patterns, and dimensional stability compared to pressure-treated spruce.

Calgary's extreme climate affects both materials differently, which impacts long-term value. Cedar naturally resists rot and insects without chemical treatment, making it ideal for Calgary's moisture cycling from chinook winds. However, cedar is a softer wood that dents easily and will turn silver-grey within one season under Calgary's intense UV at 1,045 metres elevation. Pressure-treated spruce handles structural loads well but warps, twists, and splits dramatically as it dries in Calgary's low humidity — gaps between boards can widen from 1mm to 5mm as the lumber shrinks.

Maintenance costs favor cedar over the long term. Cedar requires staining or oiling every 1-2 years to maintain its colour and protect against UV damage, but it's dimensionally stable and won't warp like pressure-treated lumber. Pressure-treated decks need restaining every 2-3 years and often require board replacement within 8-12 years due to warping and splitting. A well-maintained cedar deck can last 15-25 years, while pressure-treated typically needs significant repairs or replacement after 10-15 years in Calgary's climate.

For budget-conscious homeowners, pressure-treated makes sense for the initial build, especially if you plan to upgrade to composite decking in 10-15 years anyway. For homeowners who want natural wood beauty and are committed to regular maintenance, cedar offers better long-term performance and appearance retention in Calgary's challenging climate conditions.
