Ferndale Two Fiber Cement Products, One Standard
If you've priced out siding in Ferndale, you've probably heard both names come up: James Hardie and Cemplank. Both are fiber cement products, both are marketed as low-maintenance alternatives to wood, and on a spec sheet they can look nearly identical. We get asked often enough why we only install James Hardie and not Cemplank that it's worth laying out honestly, product by product, rather than just saying "we prefer one brand."
Fiber cement itself is the right call for this climate. Whatcom County sits under a lot of moisture: salt air rolling in off Bellingham Bay and the Strait of Georgia, driving rain off the water, and a moss season that stretches long into the year on north-facing walls and shaded lots. Whatever siding goes on a Ferndale home needs to shrug off that combination for decades, not just look good on installation day. That's where the differences between these two products start to matter.
What Cemplank Gets Right
To be fair to it, Cemplank is a legitimate fiber cement product, not a knockoff. It's non-combustible like other fiber cement siding, resists rot in a way that untreated wood never will, and it's generally priced a step below James Hardie, which makes it an understandable draw for a budget-conscious project. For a lot of applications in drier climates, it performs reasonably well.
Where Our Concerns Are
Our reservations about Cemplank aren't about the base material failing outright — they're about the details that matter most in a climate like ours, over a 30-plus year ownership horizon.
- Factory finish consistency. James Hardie's ColorPlus finish is baked on and warrantied as a system — the paint and the board are engineered together, with a documented finish warranty separate from the substrate warranty. Cemplank's factory-finish and warranty structure is less consistent across product lines, and in our experience that shows up first as color and sheen variation on a wall exposed to years of coastal sun and salt spray.
- Product line depth for wet climates. James Hardie builds region-specific HZ5 formulations aimed at exactly the freeze-moisture cycling and driving rain we get in the Pacific Northwest. Cemplank's lineup doesn't offer that same climate-zone engineering, which matters more here than it would in a dry inland market.
- Warranty structure. James Hardie's warranty is transferable to a new homeowner and widely recognized by lenders and appraisers, which matters if a client ever sells. Cemplank's warranty terms are narrower and less consistently backed at the local supply and installation level, which puts more of the long-term risk back on the homeowner.
- Availability of matched trim and accessories. James Hardie's trim, soffit, and accessory lines are made to match the siding exactly — same finish batch, same expansion behavior. With Cemplank, matching trim can mean mixing brands, which is where caulking and paint touch-ups start creeping into the maintenance schedule.
None of that means Cemplank is a bad product in the abstract. It means that when we weigh installation sensitivity, finish warranty, and moisture performance against what a Ferndale home actually goes through — salt air, driving rain, and moss creeping across shaded siding for months at a stretch — the margin tips clearly toward one product.
Why We Standardized on One Brand
We install roofing and siding for a living, not just for one job. Standardizing on James Hardie lets our crews get genuinely expert at one flashing detail, one fastening pattern, one caulking spec, and one set of manufacturer installation instructions — instead of switching systems from house to house and risking the small mistakes that show up as callbacks two winters later. It also means when we tell a homeowner what the warranty covers, we're not hedging.
James Hardie fiber cement is non-combustible, holds its ColorPlus factory finish for years without repainting, and is engineered in HZ product lines specifically for wet coastal climates like ours. The warranty is transferable, which protects resale value, and it's backed by a manufacturer with a long track record in the Pacific Northwest rather than a thinner regional presence.
What This Means for Your Project
| Consideration | James Hardie | Cemplank |
|---|---|---|
| Climate-specific formulation | HZ5 zone-engineered | General-purpose lineup |
| Factory finish warranty | Separate, transferable ColorPlus warranty | Narrower, less consistent |
| Matched trim system | Full matched trim/soffit line | Limited, often mixed-brand |
| Upfront cost | Higher | Lower |
If a lower upfront cost is the priority, we'll say so plainly rather than pretend the products are interchangeable. But for the moisture, salt air, and moss exposure a home in Ferndale or anywhere else in Whatcom County deals with year-round, we've made James Hardie our standard — it's the product we're willing to put our own name behind for the long haul.
