How does Hardie board compare to wood for fencing in the Lower Mainland?

Hardie board (fibre cement) is not a mainstream fencing material and is rarely used for fence panels in Metro Vancouver, though it has some niche applications. James Hardie products are engineered for siding, trim, and cladding applications — not structural fencing. While fibre cement is moisture-proof and rot-proof, it lacks the flexibility, fastening properties, and impact resistance that fence boards need to handle wind loads, gate swings, and the general physical abuse a fence endures over its lifespan.

The appeal of Hardie board for fencing is understandable in Vancouver's wet climate. Fibre cement is made from cement, sand, and cellulose fibres — it doesn't rot, doesn't absorb moisture, won't warp, and is immune to the moss, mildew, and algae that plague wood fences in the Lower Mainland. It comes pre-primed and can be painted any colour. On paper, it solves every moisture-related problem that wood fences face in Metro Vancouver. But the material has significant limitations in a fencing application.

Fibre cement is heavy and brittle — two properties that create real problems for fencing. A standard Hardie plank (6.25 inches wide, 12 feet long) weighs about 13 pounds, compared to 4-5 pounds for an equivalent cedar board. A 6-foot-tall fence panel using Hardie planks would weigh roughly three times as much as a cedar panel, requiring substantially heavier posts and hardware. More critically, fibre cement cracks on impact. A fence takes hits from lawnmowers, sports equipment, falling branches, and wind-driven debris. Cedar absorbs these impacts and bounces back; Hardie board fractures, and individual broken planks are difficult to replace without disturbing the surrounding boards.

Hardie board also requires special tools and fasteners. Cutting fibre cement creates silica dust that requires a respirator and dust control (a WorkSafeBC requirement). Nailing requires a pneumatic nailer with specific Hardie-approved fasteners — standard fence nails and screws can crack the material. Pre-drilling is often necessary. All of this adds labour cost and complexity compared to working with cedar, which can be cut, nailed, and screwed with standard carpentry tools.

If you're drawn to the low-maintenance, moisture-proof concept behind Hardie board, better alternatives exist for Metro Vancouver fencing. Composite fence boards (Trex, SimTek, Fiberon) deliver moisture immunity with better flexibility, lighter weight, and purpose-built fencing profiles that include tongue-and-groove or channel systems designed for fence installations. Vinyl/PVC fencing offers similar maintenance freedom with engineered panel systems. Both composite and vinyl are specifically designed as fencing products, with proper wind-load ratings, fastening systems, and warranties for outdoor fence use.

There is one niche application where Hardie board works well in Lower Mainland fencing: accent panels on masonry or concrete-post fence structures. Some custom fence builders use Hardie panels as horizontal infill between concrete or steel posts to create a modern, architectural fence. In this application, the panel is fully supported and doesn't need to flex or absorb impact. These custom installations cost $80-$150 per linear foot and are more common in commercial landscaping than residential fencing.

For residential fencing in Metro Vancouver's wet climate, Western Red Cedar remains the gold standard for natural wood, with composite and vinyl as the leading low-maintenance alternatives. All three are purpose-built for outdoor fence applications and outperform fibre cement in flexibility, weight, workability, and cost-effectiveness.
