Natural Western Red Cedar Siding Installation in Langford & Greater Victoria, BC

Authentic Western Red Cedar Siding
Timeless Pacific Northwest beauty. Engineered for coastal weather resistance by McLean Construction.
​
Nothing matches the architectural warmth, dimensional richness, and natural character of genuine British Columbia Western Red Cedar (Thuja plicata). Sourced from sustainable West Coast forests, cedar is naturally saturated with organic preservatives (thujaplicins) that protect against decay, insects, and fungal rot.
​
At McLean Construction, we blend traditional carpentry craftsmanship with modern building science. Natural timber requires precise envelope engineering to thrive in South Vancouver Island’s wet coastal winters and sunny summers. We install premium kiln-dried cedar siding strictly following the Western Red Cedar Lumber Association (WRCLA) guidelines and BC Building Code Part 9 rainscreen standards, protecting your investment against moisture cupping, tannin bleeding, and premature aging.

Frequently Asked Questions (FAQ)
How much does Western Red Cedar siding cost to install in Victoria and Langford?
In Greater Victoria and Langford, natural Western Red Cedar siding installed typically ranges between $18 and $32+ per square foot. The price depends on the grade selected (Clear Heart vs. Select Tight Knotty), the complexity of the profile (Tongue & Groove vs. Bevel lap), the prefinishing coating system, and structural sheathing preparation. For a standard 2,000-square-foot home, total investment typically ranges between $36,000 and $65,000.
How do you prevent black streaks and stains on cedar siding?
Black streaks are caused by a chemical reaction between the natural tannins in cedar and iron or low-grade galvanized fasteners. McLean Construction exclusively uses marine-grade 304 or 316 stainless steel ring-shank nails. Combined with full 6-sided pre-coating and end-grain sealing on all field cuts, this completely prevents tannin leaching and fastener corrosion.
How often does natural cedar siding need maintenance?
Maintenance depends on sun exposure, rainfall, and the finish applied:
Clear UV Protectants: Reapply every 2 to 3 years to maintain the warm amber tone.
Semi-Transparent Stains: Reapply every 4 to 6 years.
Solid Acrylic Stains: Last 7 to 10+ years between maintenance coats.
Natural Weathering (Silver-Gray Patina): Requires zero re-staining, only periodic gentle washing to remove surface dust and organic debris.
Why is a rainscreen system essential for wood siding in BC?
Under the BC Building Code Part 9, a 10mm ventilated rainscreen cavity is mandatory for coastal regions. Wood absorbs and releases ambient atmospheric humidity. A rainscreen ensures air circulates behind the cedar boards, equalizing pressure and moisture levels across both sides of the wood. This prevents the planks from cupping, warping, or rotting your underlying wall sheathing.
Can cedar siding be treated for fire resistance in interface areas like Bear Mountain?
Yes. For homes in Wildland-Urban Interface (WUI) zones such as Bear Mountain, the Highlands, or Metchosin, cedar siding can be pressure-impregnated with factory fire retardants to achieve a Class A or Class B fire rating, meeting local fire-safety requirements while retaining natural timber aesthetics.
