Western red cedar deck Vancouver grade?

Western red cedar decking in Vancouver is available in several grades, with Clear, Select Tight Knot, and Construction grades being the most common choices for deck projects. The grade you choose significantly impacts both appearance and cost, with Clear cedar costing 2-3 times more than Construction grade.

Clear Grade is the premium option with virtually no knots, uniform grain, and consistent colour. It's the most expensive at $8-15 per square foot for materials alone, but provides the most refined appearance for high-end deck projects. Clear cedar takes stain beautifully and evenly, making it ideal for decks where appearance is the top priority.

Select Tight Knot (STK) offers the best balance of appearance and value for most Metro Vancouver deck projects. STK allows small, tight knots that won't fall out over time, giving the deck character while maintaining structural integrity. Material costs run $5-9 per square foot, making it the most popular choice for residential decks. The knots actually help the wood resist splitting and checking in Vancouver's wet climate.

Construction Grade is the most budget-friendly option at $3-6 per square foot for materials. It includes larger knots, some loose knots, and more colour variation. While perfectly functional and structurally sound, Construction grade requires more careful installation to avoid loose knots and may need additional maintenance to prevent knot holes from collecting water.

Metro Vancouver's marine climate affects all cedar grades equally — the persistent moisture and 1,200mm+ annual rainfall means even premium Clear grade requires annual cleaning and re-staining every 1-2 years to prevent greying, mould growth, and surface checking. The natural tannins in Western red cedar provide some rot resistance, but consistent maintenance is essential regardless of grade.

For most homeowners, Select Tight Knot provides the optimal combination of appearance, performance, and value. The small knots add visual interest without compromising durability, and the cost savings compared to Clear grade can be invested in better structural lumber, premium stain, or additional deck features like lighting or railings.

When selecting cedar grade, also specify kiln-dried lumber to minimize shrinkage and warping during the first year. Green (wet) cedar will shrink significantly as it dries in Vancouver's climate, creating gaps between boards and potentially loosening fasteners.
