Everett Homeowners researching fiber cement siding in Everett often come across two names: James Hardie and Cemplank. Both are fiber cement products, both are sold as durable alternatives to wood and vinyl, and on a spec sheet they can look nearly identical. We get asked fairly often why we quote Hardie and not Cemplank, so here's the honest answer.
What Cemplank Gets Right
Cemplank is a real fiber cement product, not a knockoff. It's made from the same basic recipe as most fiber cement siding: cement, sand, and cellulose fiber, pressed and cured into planks and panels. It's non-combustible, it resists rot better than wood, and it holds paint or factory finish reasonably well. For a lot of markets, it's a perfectly serviceable product installed by capable crews. We're not here to tell you it's junk, because it isn't.
Where the Comparison Actually Matters: Everett's Climate
The reason product choice matters more here than in a lot of the country comes down to what Snohomish County weather does to a house over a 20- or 30-year span. Everett sits close enough to Puget Sound and the Sound's salt air to accelerate wear on lower-grade finishes and fasteners. Add driving rain off the water most of the fall and winter, plus a long moss and algae season on north- and shade-facing walls, and you've got conditions that expose the weak points in any siding system a lot faster than a dry inland climate would.
Fiber cement in general handles moisture better than wood or engineered wood siding — that's true of both Hardie and Cemplank. The differences that matter show up in three places: the factory finish, the engineering behind the plank, and what backs the product after it's on the wall.
Factory Finish and Long-Term Fading
James Hardie's ColorPlus finish is baked on in a multi-coat factory process specifically engineered to resist UV fade and moisture intrusion at the plank's cut edges, with color-matched caulk and touch-up available for the life of the finish warranty. Cemplank's finish options vary more by distributor and region, and in our experience the factory coating systems available to us locally haven't matched Hardie's documented fade and adhesion performance over time. In a climate with as much rain exposure as Everett gets, a finish that's marginal on edge sealing shows it within a few years — chalking, streaking, or moisture creeping in at butt joints.
Climate-Engineered Product Lines
Hardie makes region-specific "HZ" formulations — different plank engineering for humid, wet climates like ours versus dry or freeze-heavy regions. That's not marketing fluff; the moisture-management performance of a fiber cement plank actually changes based on how it's formulated. Cemplank doesn't offer that same regional engineering distinction in the products available to us here, which means you're getting a general-purpose fiber cement plank rather than one built for the specific rain and humidity load Snohomish County puts on a wall.
Warranty Structure
This is the practical one for homeowners. James Hardie backs its siding with a strong, transferable non-prorated warranty on the substrate and a separate finish warranty on ColorPlus products, and Hardie stands behind installer network claims in a way that's well documented and consistent nationwide. Cemplank's warranty coverage has historically been less consistent and harder to lean on if something goes wrong five or ten years in — which matters a lot on a coastal property where you're already fighting salt air and moss for the life of the siding.
Side-by-Side Summary
| Factor | Cemplank | James Hardie |
|---|---|---|
| Material | Fiber cement | Fiber cement |
| Factory finish options | Varies by distributor | ColorPlus, engineered for UV/moisture |
| Climate-specific engineering | General purpose | HZ formulations by region |
| Warranty consistency | Variable | Strong, transferable, well documented |
| Non-combustible | Yes | Yes |
Why We Standardized on One Product
We made a decision a while back to install only James Hardie siding, full stop. Part of that is the product itself — the finish durability and climate-specific engineering hold up better under Everett's rain and salt exposure than the alternatives we've evaluated. Part of it is simpler than that: when you install one system and know it inside out, you get better at flashing details, fastener spacing, and joint sealing on that specific product than if you're juggling five different manufacturers' spec sheets. On a house that has to shed driving rain and shrug off a wet, mossy PNW winter every year for decades, that installation consistency matters as much as the plank itself.
