Ferndale Siding One Product, No Exceptions
Homeowners in Ferndale sometimes ask 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 holds up in Whatcom County — the salt air coming off Bellingham Bay, the driving winter rain, the long stretch of moss season under gray skies — and settled on one product system: James Hardie fiber cement. We install it exclusively, on every job, because we're not interested in standing behind a product we have doubts about.
This page isn't a sales pitch so much as an explanation of what Hardie actually is, how it's built, and why the details matter more here than in drier climates.
What Fiber Cement Actually Is
James Hardie siding is made from cellulose fiber, sand, and Portland cement, cured under controlled conditions. That composition matters for three reasons specific to our region:
- Non-combustible. Fiber cement doesn't feed a fire the way wood-based products can, which matters as wildfire smoke seasons have become a regular late-summer reality even here on the wet side of the state.
- Dimensionally stable. It doesn't swell and contract with moisture the way wood or wood-composite products do, which matters when a home sees months of damp fall and winter weather followed by drier summer stretches.
- Rot-proof core. There's no organic wood fiber for moisture to break down over time, which is the main reason we stopped considering wood-based and composite alternatives.
The HZ5 Engineering Behind It
James Hardie makes region-specific product formulations, and that's a big part of why we trust it here. Their HZ5 line is engineered for climates with significant moisture exposure and freeze-thaw cycling — which describes Whatcom County's weather pattern well enough. It's not a marketing label; the manufacturing formulation is genuinely tuned for wetter, harsher climates versus the HZ10 formulation used in hot, dry regions of the Southwest. We install the version engineered for what actually happens outside your walls in Ferndale, not a generic national product.
ColorPlus Factory Finish
A big part of long-term siding performance is the finish, not just the substrate. James Hardie's ColorPlus finish is baked on in a factory setting under controlled conditions, rather than field-painted after installation. A few practical implications:
- The finish resists fading and chalking better than a job-site paint job, which matters under the UV exposure of long summer daylight hours even in a generally cloudy climate.
- Touch-up products are formulated to match, so nail heads and cut edges don't stand out.
- You get a more consistent color across the entire job, since it isn't dependent on field conditions, temperature, or painter technique on the day of installation.
For homeowners who want a specific look — deep grain cedar-style lap, smooth modern panel, shingle profiles — ColorPlus removes a lot of the maintenance-cycle repainting that comes with field-finished siding.
Product Lines We Work With
| Line | Typical Use |
|---|---|
| HardiePlank Lap | Most common siding profile — traditional lap look, several textures |
| HardiePanel | Vertical panel siding, often used for modern facades or accent sections |
| HardieShingle | Staggered or straight-edge shingle look without the maintenance of real wood shingle |
| HardieTrim | Trim boards that match the siding finish system for a cohesive final look |
Warranty That Actually Transfers
James Hardie backs its siding with a long, transferable limited warranty, and the ColorPlus finish carries its own separate finish warranty. That two-part structure matters if you sell your home — a fresh warranty tied to a national manufacturer means more to a buyer than a verbal assurance from a contractor who painted the job on-site.
Installation Is What Makes or Breaks It
Fiber cement is only as good as the install. Correct fastener placement, proper clearances above rooflines and decks, correctly flashed penetrations, and manufacturer-spec gapping and caulking all affect how the product performs over 20, 30, or more years — especially with the amount of wind-driven rain Whatcom County sees off the Strait. We install strictly to James Hardie's published specifications because that's the only way the warranty and the performance actually hold up. It's also the main reason we don't spread ourselves across five different siding brands — installing one system correctly, every time, is how we stand behind our work.
Is It Right for Every Home?
Fiber cement costs more upfront than vinyl and is heavier to install than most composite products, which we address honestly in our other product comparison pages. But for Ferndale homes facing salt air, sustained rain, and moss-friendly shade, it's the product we're willing to put our name behind.
