Ferndale Siding Fiber cement siding has earned its reputation in Whatcom County for good reason — it shrugs off moisture, resists insects, and holds paint far longer than wood. But "fiber cement" is a category, not a single product, and the brand behind the board matters more than most homeowners realize. Allura is one of the other major fiber cement manufacturers on the market, and we get asked about it often enough that it's worth explaining plainly: we don't install it. Not because it's a scam or a bad board in some dramatic sense, but because when we weighed it against James Hardie on the specifics that matter for homes in this climate — factory finish quality, product engineering for our exact weather pattern, and warranty structure — Hardie came out ahead on every count that affects you fifteen years down the road.
This page walks through what Allura actually is, what it does reasonably well, and where the trade-offs live. Then it explains what we install instead and why.
What Allura Fiber Cement Actually Is
Allura manufactures fiber cement lap siding, panels, and trim using the same basic recipe as every other player in the category: Portland cement, sand, cellulose fiber, and water, cured under pressure. Structurally, it's a legitimate building material. It's non-combustible, it doesn't rot, and termites have no interest in it. On paper, a lot of Allura's marketing reads similarly to Hardie's — because the underlying chemistry is genuinely comparable.
Where the products diverge is in manufacturing consistency, factory finish systems, regional engineering, and the depth of the company's presence and accountability in the Pacific Northwest market. Those aren't marketing points — they're the things that show up as maintenance headaches or warranty disputes years after installation, long after the crew that installed it has moved on to other jobs.
Where Allura Holds Up
We'll give credit where it's due, because pretending otherwise wouldn't be honest:
- Core material performance. Fiber cement as a category resists moisture intrusion, pests, and fire far better than wood, vinyl, or engineered wood products like LP SmartSide.
- Price positioning. Allura is often priced a step below Hardie, which can matter on tight budgets.
- Basic product lineup. Allura offers lap siding, shingle-style panels, and trim boards that cover the standard needs of a residential exterior.
If a homeowner already has Allura siding installed and it's holding up, we're not going to tell you it's failing or that you need to rip it off the house. That's not the point of this page. The point is what we choose to put on a home when a customer is trusting us with the decision from scratch.
Where We See the Real Trade-Offs
Factory Finish Consistency
Hardie's ColorPlus finish system is baked on in a controlled factory environment with a specific multi-coat process, and it carries its own dedicated finish warranty separate from the substrate warranty. Allura also offers factory-finished options, but the depth of color selection, finish warranty terms, and long-run consistency across production batches has historically trailed Hardie's — and in a market like ours, where boards sit under UV exposure in summer and saturated moisture nine months of the year, finish durability isn't cosmetic. It's the first line of defense protecting the substrate underneath.
Climate-Specific Engineering
Hardie builds distinct product lines engineered for specific climate zones — HZ5 for freeze-thaw regions, HZ10 for the humid, moisture-heavy zones that describe most of coastal Washington. That's not a marketing label; it changes the formulation to manage moisture absorption and expansion behavior for the climate the board is actually going into. Ferndale sits close enough to the Strait of Georgia that homes deal with salt-laden air, long stretches of driving rain off the water, and a moss season that can run most of the year on north-facing walls. A product engineered generically, without that regional split, is starting from a lower baseline for the exact conditions this county throws at a house.
Installation Sensitivity
Fiber cement in general is less forgiving than vinyl — it has to be cut, fastened, and caulked correctly, with proper clearances at grade and butt joints treated correctly, or moisture finds its way in regardless of brand. That part is true of any fiber cement product, including Hardie. But Hardie's documentation, installer training network, and certified-contractor program are more extensive and more consistently enforced in this region, which reduces the odds of a crew cutting corners on details that don't show up as a problem until year eight or nine.
Warranty Structure and Backing
Hardie's warranty is transferable to a subsequent homeowner (within the stated terms), which matters for resale — a real consideration in a market where houses change hands. Hardie's size and market presence also mean the company has a long track record of standing behind claims across decades of installations nationwide. Allura's warranty coverage exists and is not fraudulent, but the depth of field support and claims history in the Pacific Northwest specifically is thinner, which is a real factor when you're trying to gauge how a warranty claim will actually go in practice, not just what the paper says.
Side-by-Side: What We Weighed
| Factor | Allura | James Hardie |
|---|---|---|
| Core material | Fiber cement, non-combustible | Fiber cement, non-combustible |
| Climate-specific formulation | Standard formulation | HZ10 zone engineering for PNW moisture |
| Factory finish system | Factory-finish options available | ColorPlus with separate finish warranty |
| Warranty transferability | Manufacturer warranty applies | Transferable limited warranty |
| Regional installer network depth | Present, smaller footprint here | Established, deep contractor network in WA |
| Typical price position | Often below Hardie | Mid-to-upper range for the category |
Why This Matters More in Ferndale Than Elsewhere
A siding decision in a dry inland climate carries less risk either way — moisture pressure is lower, and a formulation gap is less likely to surface as a real problem. That's not the situation here. Whatcom County homes face salt air moving in off Bellingham Bay and the Strait, rain that doesn't just fall but drives sideways against north and west elevations for days at a stretch, and a moss and algae season that can run nearly year-round on shaded walls. Every one of those conditions punishes weak points in a siding system — finish that chalks or fades early, joints that weren't detailed correctly, or a substrate that wasn't formulated for sustained moisture exposure. We'd rather start from the product with the deepest engineering margin for exactly those conditions than find out five years in that a lower-cost option needed more margin than it had.
What We Install Instead
James Hardie fiber cement, exclusively, is what goes on every home we side. That's not a sales pitch buried in an educational article — it's a standard we set because we don't want to be the crew that installed something we couldn't stand behind fifteen years later. Hardie's HZ10 product lines are engineered for the exact moisture and humidity profile of the coastal Pacific Northwest, the ColorPlus finish is factory-cured and backed by its own warranty, and the transferable limited warranty gives homeowners real protection whether they stay in the house for decades or sell in five years.
Questions to Ask Any Siding Contractor
Whether you go with us or someone else, these are the questions that separate a straight answer from a sales pitch:
- Which specific fiber cement brand and product line are you quoting, and why that one?
- Is the finish factory-applied, or will it be field-painted after installation?
- What does the manufacturer's warranty actually cover, and is it transferable if I sell the house?
- Is the crew doing the installation certified or trained specifically on this product's installation requirements?
- How does this product's formulation account for our regional moisture and rain exposure?
The Honest Bottom Line
Allura is a real fiber cement manufacturer, not a product we're trying to scare anyone away from out of spite. If it's already on your house and performing, that's fine. But when we're the ones making the recommendation from a blank slate, on a home that has to survive Whatcom County's salt air, driving rain, and moss season for the next thirty years, the depth of climate-specific engineering, finish warranty, and regional track record tip clearly toward Hardie. That's the standard we hold every job to, and it's why we don't carry Allura on our trucks.
