Semiahmoo Siding One Product, One Standard
We get asked a lot why we don't offer a menu of siding brands the way some contractors do. The honest answer is that we looked at what actually survives on homes along the Semiahmoo waterfront and throughout Whatcom County, and we made a call: we install James Hardie fiber cement siding, and nothing else. Not because we have a marketing deal with Hardie, but because after years of tear-offs and re-sides in this specific climate, it's the product we're comfortable standing behind.
What This Climate Actually Does to Siding
Semiahmoo sits right on the water, which means salt-laden air is a daily fact of life, not an occasional event. Add in driving rain off the Strait, long stretches of gray, damp weather, and a moss season that can run half the year on north-facing walls, and you've got a climate that's genuinely hard on exterior building materials. Wood-based products swell, splinter, and rot. Vinyl can warp, fade, and crack in temperature swings and impact. Even other fiber cement products aren't all engineered the same way for coastal exposure. We wanted one product we could install to spec and trust for decades, not one we'd be back to patch in five years.
Why Fiber Cement, and Why Hardie Specifically
Fiber cement itself is the right category for this region — it doesn't feed moss and mildew the way wood does, it holds paint and factory finish far better than wood siding, and it's non-combustible, which matters more every wildfire season even out here on the coast. Within fiber cement, James Hardie is the manufacturer that engineers products specifically for climate zones. Their HZ5 line is formulated for regions like ours, with wetter, cooler conditions, versus the HZ10 line built for hot, dry climates. That's not a marketing distinction — it changes how the board is formulated to resist moisture-related damage over the long run.
ColorPlus Factory Finish
Most of what we install uses Hardie's ColorPlus finish — a factory-applied, baked-on finish that's more consistent and more durable than field-applied paint. In a climate where a fresh paint job on wood or primed siding might need attention again within a handful of years, a factory finish designed to hold color and resist fading in UV and salt air is a real difference in long-term maintenance, not just a convenience.
Product Lines We Work With
- HardiePlank lap siding — the most common choice, available in several textures and exposures
- HardieShingle — for homes wanting a shingle-style look without the maintenance of real cedar shingles
- HardiePanel — vertical panel applications, often paired with board-and-batten detailing
- HardieTrim — matching trim boards so the whole exterior system is consistent, not mixed materials aging at different rates
Warranty and Longevity
James Hardie backs its siding products with a long, transferable limited warranty — a meaningful factor for homeowners in Semiahmoo who may sell down the road, since it can pass to the next owner rather than expiring with the original purchase. But a warranty is only as good as the installation behind it. Hardie's warranty terms assume the product was installed to their published specifications: correct clearances from grade and roofing, proper fastening, correct flashing and water management behind the cladding, and factory-finished cuts sealed properly. This is exactly why we don't treat installation as an afterthought — it's the difference between siding that performs for decades and siding that fails early despite being a good product.
What We Don't Install, and Why That's a Standard, Not a Judgment
We don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or raw cedar siding. Each of those has legitimate uses and can look good on the right home in the right climate. Our decision not to install them isn't a claim that they're bad products everywhere — it's that we're not willing to install something in this specific salt-air, high-rainfall, moss-prone environment that we don't have full confidence will hold up without heavier maintenance or earlier replacement. We'd rather install one product exceptionally well than several products adequately.
What This Means for Your Project
Standardizing on one manufacturer also means our crews know the product inside and out — the clearances, the fastening patterns, the flashing details specific to Hardie's requirements, and how to keep factory-cut edges sealed against moisture. That familiarity is part of what protects the warranty and the finished look of your home.
