One Product, No Exceptions
Homeowners sometimes ask why we don't offer a menu of siding brands the way some contractors do. It's a fair question, and the answer is simple: after years of installing and repairing siding around Ferndale and the rest of Whatcom County, we settled on James Hardie fiber cement as the only product we're willing to put our name on. Not because it's the cheapest option, and not because it's the easiest to install — it's neither. We chose it because it holds up to what this climate actually does to a house.

What This Climate Demands
Ferndale sits close enough to the water that salt air is a real factor on siding, trim, and fasteners. Add in driving rain off the Strait, a moss season that can stretch from October into May, and long stretches where painted wood siding never fully dries out between storms, and you've got conditions that expose weak points in a siding system fast. We've seen what happens to products that aren't built for this — swelling at butt joints, moss and algae staining that won't scrub off, paint that fails years ahead of schedule, edges that soften after repeated wetting. James Hardie's fiber cement doesn't solve every maintenance issue a home will ever have, but it's engineered specifically for moisture-heavy, coastal-influenced climates like ours, and that matters more here than in drier parts of the state.
What James Hardie Actually Is
James Hardie siding is fiber cement: a mix of cement, sand, and cellulose fibers, cured and engineered to be dimensionally stable. It doesn't expand and contract the way wood-based siding does, it's non-combustible, and it takes moisture very differently than wood or wood-fiber products — it doesn't absorb and swell the same way, and it isn't a food source for the fungi that cause rot. For a region where a house might see rain more than half the year, that stability is the whole point.
The HZ5 Line
James Hardie makes climate-specific product lines, and for Whatcom County we install the HZ5 formulation, engineered for regions with more moisture, freeze-thaw cycling, and harsher weather exposure than the HZ10 line built for hot, humid climates. This isn't a marketing distinction — the formulation and testing behind it are built around exactly the kind of weather Ferndale gets.
ColorPlus Factory Finish
Most of the jobs we do use Hardie's ColorPlus finish: a baked-on, factory-applied coating that's more consistent and more UV- and fade-resistant than field-applied paint, with a 15-year finish warranty backing it. Field painting is still available for homeowners who want a fully custom color, but ColorPlus removes one of the biggest long-term maintenance headaches with painted siding — repainting a full house exterior every several years because sun and rain have worked the finish loose.
Lines We Install
- HardiePlank lap siding — the most common choice, available in several exposure widths and textures (smooth, cedarmill).
- HardiePanel vertical siding — often used for board-and-batten looks or modern facades.
- HardieTrim — matched trim boards for a clean, integrated finish at corners, windows, and fascia.
- HardieSoffit — pre-finished soffit panels that hold up in the same wet conditions as the field siding.
Why Installation Quality Is Non-Negotiable
Fiber cement is only as good as the installation behind it. Hardie's own warranty terms require specific clearances, fastening patterns, joint treatment, and flashing details — get those wrong and you can undercut the product's performance no matter how good the material is. That's part of why we don't spread our crews thin across multiple siding systems. We install one product, we install it to spec every time, and we know the details that matter in this region specifically: proper ground clearance given how wet Ferndale winters get, correct caulking and flashing at penetrations, and butt joint treatment that keeps water from finding its way behind the plank.
The Warranty, Plainly
James Hardie backs its siding with a transferable limited warranty (typically 30 years on the substrate for lap and panel products, with separate coverage on ColorPlus finish), which matters if the home ever sells. Warranty terms and lengths vary by product and are worth reviewing directly with us before a project starts, but the structure is more substantial than what's typical for painted wood or vinyl systems.
What This Standard Means for You
Standardizing on one product means we're not trying to fit every home into whatever's on sale that month. It means our crews are deeply practiced in one installation system rather than juggling several, and it means when we quote a Ferndale project, we're quoting a siding system we've watched perform through actual Whatcom County winters — not a spec sheet from a manufacturer in a different climate zone.
If you're planning a siding replacement and want to talk through what James Hardie would look like on your home — product line, color, and a straightforward cost range — we're happy to come take a look.
