Ferndale Two Fiber Cement Products, One Standard We Hold To
If you've been pricing out siding in Ferndale or anywhere else in Whatcom County, you've probably noticed that "fiber cement" isn't a single product — it's a category. Cemplank and James Hardie both make fiber cement lap siding, panels, and trim, and on paper they can look similar: same base material (cement, sand, cellulose fiber), same general pitch of durability and fire resistance compared to wood or vinyl. We get asked fairly often why we install only James Hardie and turn down jobs that call for Cemplank. It's a fair question, and the honest answer isn't that Cemplank is a bad product — it's that we standardized on one system, and Hardie is the one we trust for this climate and the one we're willing to warranty our labor against.
What Cemplank Gets Right
Fiber cement as a category earns its reputation. It doesn't rot, it resists pests, and it holds paint or factory finish far longer than wood siding. Cemplank is a legitimate fiber cement product, and a well-installed run of it will outperform vinyl or untreated wood siding in almost every practical way. We're not telling clients to avoid fiber cement — quite the opposite. Our issue isn't with the category, it's with running two different fiber cement systems side by side as a small, specialized contractor.
Why We Don't Install It Anyway
A few practical reasons drove this decision, and they're worth laying out plainly:
- Climate-specific engineering. James Hardie sells region-specific product lines — HZ5, for example, is engineered for the wetter, milder climates found in the Pacific Northwest, with a formulation aimed at resisting moisture-related damage in areas that see long stretches of rain and humidity rather than freeze-thaw cycles. Whatcom County's climate — salt air off the Strait of Georgia and Bellingham Bay, driving winter rain, and a moss season that can run half the year on north-facing walls — is exactly the kind of environment that product engineering is built around. We didn't find the same depth of regionally-specific formulation documentation from Cemplank, and for siding that's going to sit on a wall for decades, that's not a detail we're willing to guess on.
- Factory finish consistency. We install Hardie's ColorPlus factory-finished siding almost exclusively, which bakes the color and finish on under controlled conditions before the boards ever reach the jobsite. That matters for touch-up availability, color matching on future repairs, and finish longevity in salt air, which is harder on field-applied paint than on a factory-cured finish. Switching between manufacturers means juggling two different finish systems, two different touch-up kits, and two different sets of long-term expectations for our clients — and that's where mistakes and mismatched warranties creep in.
- Warranty structure. Hardie's warranty is transferable to a subsequent homeowner within a defined window, which matters in a market where houses change hands. We've built our installation process, our fastener schedule, and our flashing details specifically around what Hardie's warranty requires to stay valid. Running a second product line would mean maintaining two separate warranty compliance standards, and if we're being honest, that's a good way to eventually get one of them wrong.
- Supply chain and support. Being certified and set up as a dedicated Hardie installer gives us a consistent supply of matching trim, starter strips, and accessories, plus manufacturer technical support when we hit an unusual detail — a tricky roofline, an odd corner condition, a retrofit over old siding. Splitting our crew's expertise and our supplier relationships across two fiber cement brands would thin out that depth rather than add to it.
What This Means If You're Comparing Quotes
If another contractor has quoted you Cemplank, that doesn't automatically mean you're getting a bad product — it means you should ask the same questions we asked ourselves: What product line is being specified for this climate zone? Is the finish factory-applied or field-painted? What does the warranty actually cover, and does it transfer if you sell the house? How is color-matched trim sourced for future repairs? Those answers matter more than the brand name on the box.
What We Install Instead
We put James Hardie fiber cement on homes because it's non-combustible, it's engineered specifically for climates like ours — with the salt-laden air coming off the water, the sustained wet season, and the moss growth that plagues shaded siding here — and because the ColorPlus finish and product warranty give homeowners something concrete to rely on years down the road, not just at closing. It also lets our crew focus on doing one system extremely well rather than two systems adequately.
A Straightforward Comparison
| Factor | What We Weighed |
|---|---|
| Climate engineering | Region-specific formulation (e.g. HZ5) built for Pacific Northwest moisture exposure |
| Finish | Factory-applied ColorPlus finish vs. field-applied options |
| Warranty | Defined, transferable coverage tied to certified installation practices |
| Crew expertise | One system mastered in depth vs. two systems split thin |
