Anacortes Two Products, One Category
If you've gotten a few siding quotes in Skagit County, you've probably noticed that "fiber cement" isn't a single brand — it's a category, the same way "SUV" covers a dozen different manufacturers. James Hardie and Cemplank both fall under that umbrella. Both are made from a blend of Portland cement, sand, and cellulose fiber, pressed and cured into planks, panels, and trim. On paper, that makes them look like interchangeable products, and a lot of homeowners assume any fiber cement bid is basically the same bid with a different label stuck on it.
It isn't. We've looked closely at both products, and we made a deliberate decision years ago to install only James Hardie. This page explains why, without trashing the competition — Cemplank is a real fiber cement product, not a knockoff, and it has a legitimate place in the market. But "legitimate" and "what we're willing to put our name behind on an Anacortes home" turned out to be two different bars.
Where Cemplank Gets It Right
Credit where it's due: Cemplank is genuine fiber cement, not vinyl or engineered wood dressed up to look like it. It's non-combustible, it resists rot in a way that untreated wood siding never will, and it holds paint better than most wood substrates. For a homeowner comparing it against vinyl or LP SmartSide, Cemplank is a step up in almost every category that matters — durability, fire resistance, and long-term maintenance.
Where the two products start to diverge is in the details that don't show up on a spec sheet — manufacturing consistency, factory finish quality, climate engineering, and the depth of the support system standing behind the product once it's on your wall. Those details matter more in a place like Anacortes, sitting right on the water with a marine layer that doesn't fully let up for half the year, than they would in a dry inland climate.
Where the Comparison Gets Real
The honest answer to "which fiber cement is better" is: it depends what you're weighing, and how much you value consistency versus a lower bid. Below is the breakdown we walk homeowners through.
| Factor | James Hardie | Cemplank |
|---|---|---|
| Factory finish | ColorPlus baked-on finish, engineered for UV and moisture, touch-up system matched to each color | Factory-primed or painted options vary by product line; color-match touch-up systems are less standardized |
| Climate engineering | HZ5 product line engineered specifically for Pacific Northwest freeze-thaw and moisture exposure | General fiber cement formulation; not marketed with a regional climate-zone system |
| Installer network | Large base of Hardie-trained, certified installers in Western Washington with manufacturer backing | Smaller, less consistent local installer base |
| Warranty | Long-term, transferable limited warranty with clearly published terms | Warranty exists but terms and transferability are less consistently documented across dealers |
| Product line depth | Full system: lap, panel, shingle, trim, soffit, all engineered to work together | Narrower product range in most markets we've priced against |
Manufacturing Consistency: Why It's Not Just Marketing
Fiber cement is a manufactured product, which means quality depends entirely on the consistency of the plant that makes it. Batch-to-batch variation in cement, fiber, and sand ratios shows up years later as differences in how planks take paint, how they cut, and how evenly they weather. James Hardie runs a large-scale, tightly controlled manufacturing process with a long track record in North America, and that scale lets them hold tighter tolerances plank to plank and shipment to shipment.
Cemplank is produced to a real industry standard, and it's not an inconsistent product in any dramatic sense — but it doesn't have the same manufacturing footprint or the same decades of North American climate data behind it. When we're installing siding that's supposed to last 30-plus years on a home exposed to Rosario Strait weather, we'd rather bet on the manufacturer with the longer, more consistent track record.
Factory Finish: The Part Homeowners Underestimate
The single biggest maintenance factor on any fiber cement siding is the finish, not the substrate underneath it. Raw fiber cement is durable, but paint failure on fiber cement siding is almost always a finish problem, not a material problem.
Hardie's ColorPlus finish is baked on at the factory in a controlled environment, using a multi-coat process engineered specifically for their board. It comes with a matched caulk and touch-up paint system, so repairs blend instead of leaving a visible patch. Cemplank offers primed and factory-finished options too, but the finish systems and touch-up matching aren't standardized the same way across dealers and regions — which means the quality of what you actually get can depend more on which distributor or applicator supplied your particular order.
In a marine climate with driving rain and long stretches of damp, low-light weather, a factory finish that's engineered as a system — not just "primed and ready for field paint" — is the difference between a home that needs repainting in eight years and one that holds its color for two to three decades.
Built for This Climate, Not Just Rated for It
Anacortes sits on salt water, which means every exterior surface on a home here deals with airborne salt, near-constant humidity, and a moss season that can run from October well into spring. Wood rots, vinyl gets brittle and stained, and even fiber cement can underperform if it wasn't engineered with this kind of exposure in mind.
James Hardie's HZ5 product line was specifically engineered for the moisture and freeze-thaw conditions of the Pacific Northwest — it's not a generic national product with a regional sticker on it. Cemplank doesn't market a comparable zone-specific engineering system, which doesn't necessarily make it unfit for this climate, but it does mean there's less documented, product-specific engineering behind how it's expected to perform against salt air and sustained wet-season exposure over decades. For a coastal Skagit County installation, that's not a detail we're willing to gamble on.
Warranty Structure: Read Past the Headline Number
Every fiber cement brand advertises a long warranty, and on paper the numbers can look similar. The real difference is in the fine print — what's covered, whether it's prorated, whether it transfers to a new owner if you sell the house, and how straightforward the claims process actually is.
James Hardie's warranty terms are published, consistent, and transferable, which matters a lot for resale value — a documented, well-known warranty is something a buyer's inspector or agent can actually verify. Cemplank's warranty coverage exists, but it's not backed by the same brand recognition or claims infrastructure, and terms can vary more by dealer and region. If a warranty claim ever comes up ten or fifteen years down the road, we want our clients dealing with a manufacturer that makes that process simple, not one where the paperwork trail is thinner.
Installer Network and Long-Term Support
A siding product is only as good as the installation behind it, and both products are sensitive to correct fastening, clearances, and flashing details. The difference is how much manufacturer-backed training and support exists locally. James Hardie has invested heavily in contractor training and certification programs across Western Washington, which means there's a deep bench of crews who've been specifically trained on their fastening patterns, joint treatments, and climate-specific installation requirements.
Cemplank doesn't have the same density of certified installers in this region, which raises the odds that any given crew installing it is working from general fiber cement knowledge rather than product-specific training. Installation errors on fiber cement don't usually show up as a problem on day one — they show up as trapped moisture, cracked caulk joints, or premature paint failure three to seven years later. That lag is exactly why we don't cut corners on which product and which training pipeline we build our crews around.
What to Ask Any Contractor Bidding Fiber Cement Siding
Whether you end up going with us or someone else, these are the questions that actually separate a solid fiber cement bid from a risky one:
- Which specific manufacturer and product line is being quoted — not just "fiber cement," but the actual brand and series
- Whether the boards are factory-finished or field-painted, and what the touch-up system looks like
- What the manufacturer's warranty actually covers, whether it's prorated, and whether it transfers on sale
- Whether the installers are manufacturer-trained or certified on that specific product
- What fastening pattern and clearances they'll use at the foundation, windows, and roofline — critical in a wet climate
- How touch-up paint and replacement planks will be sourced years down the road if repairs are ever needed
If a contractor can't answer those clearly, that's worth knowing before you sign anything — regardless of which fiber cement brand is on the quote.
Why We Standardized on One Product
We used to think about this the way a lot of homeowners do: fiber cement is fiber cement, so why not offer more options and let price decide it? What changed our mind was watching the difference play out over time — in finish durability, in how warranty claims actually got handled, and in how consistently a well-trained crew could execute the install. Standardizing on James Hardie let us build deep, specific expertise with one system instead of spreading our crews thin across multiple products, each with its own fastening rules, finish systems, and quirks.
For a home on the water in Anacortes, or anywhere else in Skagit County dealing with salt air, driving rain, and a moss season that doesn't quit, that consistency is worth more than a slightly lower bid on a product with a thinner track record in this exact climate.
