Bellingham Allura Is a Legitimate Fiber Cement Product
Let's start with the honest part: Allura is real fiber cement, not vinyl dressed up to look like something better. It's made from the same basic recipe as every fiber cement siding on the market — Portland cement, sand, and cellulose fiber, cured under pressure. That means it shares fiber cement's core advantages over wood or vinyl: it doesn't rot, it resists insects, and it holds up to fire far better than wood-based siding. If you're comparing Allura against LP SmartSide or cedar, Allura wins on durability almost every time.
So this page isn't a takedown. It's an explanation of why, after installing fiber cement siding across Bellingham and the rest of Whatcom County, we made James Hardie our standard and stopped bidding jobs with Allura.
Where the Two Products Actually Differ
The differences that matter aren't about whether the board is "good" or "bad" — they're about manufacturing process, finish system, and how those two things play out on a house that sits through a Pacific Northwest winter.
Factory Finish
James Hardie's ColorPlus finish is baked on at the factory using a multi-coat process, then backed by a separate finish warranty covering fading and peeling. Allura's product line has historically leaned more heavily on primed boards meant for field painting, with factory-finished options less consistently available depending on the profile and region. Field-applied paint is only as good as the crew that applies it and the weather on the day they do it — and in Bellingham, where we can go weeks without a solid dry-paint window between September and June, that's a real scheduling constraint, not a small one.
Moisture Behavior at the Cut Edge
Fiber cement is engineered to resist water, but every board has a vulnerable point: the cut edge, where the factory coating stops and the raw material is exposed during installation. Hardie's HZ5 product line and installation specs are built around Pacific Northwest moisture exposure specifically, with edge-sealing and clearance requirements that are well documented and widely trained on by local crews. Allura's install specs cover the same fundamentals, but the manufacturer-specific detailing and the pool of installers trained to their exact spec are thinner in this region. That gap between "the product can handle it" and "the crew consistently executes to spec" is where problems start on real jobs — not just with Allura, with any fiber cement product installed by a crew unfamiliar with its particular requirements.
Warranty Structure
Hardie's warranty is transferable, well-established, and has been tested against decades of claims across wet climates like ours. Allura's warranty coverage exists too, but it's a newer name in a lot of markets (the product has gone through a couple of ownership and branding changes over the years), which makes long-term claims history harder for a homeowner to evaluate. When you're putting siding on a house you plan to own for twenty-plus years in a marine climate, warranty track record isn't a formality — it's part of the product.
Why This Matters More in Bellingham Than Elsewhere
A siding product's weak points show up fastest in the climate that stresses them hardest. Whatcom County gets a combination that's tough on any exterior building material: salt air rolling off Bellingham Bay and the Strait, driving rain that hits siding sideways during winter storms, and a moss season that runs long because things simply don't dry out here the way they do east of the Cascades. Salt air accelerates corrosion at fasteners and trim. Driving rain finds every gap in a flashing detail or cut edge that wasn't sealed. A long damp season means paint and coatings get less time to cure and more time to be tested. None of that is unique to Allura — it's why we're particular about fiber cement in general — but it's also why we'd rather install the product and finish system with the deepest track record in wet coastal climates than the one with a thinner local installation history.
What We Install Instead
We standardized on James Hardie because it lets us give Whatcom County homeowners a non-combustible fiber cement siding with a factory-applied finish system built for exactly this weather, backed by a warranty structure with a long claims history, installed by crews trained specifically to Hardie's HZ5 spec. That's not brand loyalty — it's us not wanting to guess on a product's edge cases when the house has to survive forty more winters of rain off the water.
