Is knotty cedar decking significantly cheaper than clear cedar in the Vancouver area?

Yes, knotty cedar decking is significantly cheaper than clear cedar in Metro Vancouver — typically 30-50% less expensive. Clear cedar can cost $8-15 per square foot for materials alone, while knotty cedar runs $4-8 per square foot, making it an attractive option for budget-conscious homeowners who still want the beauty and natural rot resistance of BC's signature decking wood.

Knotty cedar includes boards with sound, tight knots that are an integral part of the wood grain. These knots are natural characteristics that don't compromise structural integrity when they're tight and well-adhered to the surrounding wood. The grade typically used for decking is "Construction" or "Standard" grade, which allows knots up to a certain size while excluding loose knots, splits, and other defects that could affect performance.

Clear cedar is graded to be virtually knot-free, with only minimal pin knots allowed. This creates a uniform, refined appearance that many homeowners prefer for high-visibility decks, but it comes at a premium price because clear boards must be cut from the heart of larger, older trees — a increasingly scarce resource.

In Metro Vancouver's wet climate, both grades perform equally well structurally and require the same maintenance schedule. The knots in knotty cedar actually contain higher concentrations of natural preservatives (tannins and oils) that help resist moisture and decay. However, knots can occasionally become loose over time as the wood expands and contracts with seasonal moisture changes, and they may check (develop small cracks) more readily than clear wood.

For most Metro Vancouver deck projects, knotty cedar offers excellent value. The natural character and grain variation actually complement the Pacific Northwest aesthetic, and the cost savings can be substantial — on a 300 square foot deck, choosing knotty over clear cedar might save $1,200-2,100 in material costs alone. This savings can be redirected toward better structural hardware, upgraded railings, or professional installation.

Consider clear cedar when you want a formal, uniform appearance, the deck is highly visible from main living areas, or you're building a premium outdoor entertaining space where aesthetics are the top priority. Choose knotty cedar when you appreciate natural wood character, want to maximize your budget, or you're building a more casual family deck where function matters more than formal appearance.

Both grades require identical maintenance in Vancouver's climate — annual cleaning and re-staining or re-oiling to prevent moisture penetration, mould growth, and UV graying. The performance difference is minimal, but the cost difference is substantial.
