Lynden Siding Homeowners in Lynden researching siding replacement sometimes come across Allura fiber cement (the product line that used to carry the Cemplank and Maxitile names) and ask why we don't offer it. It's a fair question. Allura is a real fiber cement manufacturer, not a knockoff, and the raw chemistry — cement, sand, and cellulose fiber pressed and cured into a board — is fundamentally the same category as what we do install. So we want to explain our reasoning honestly rather than just say "we don't do that one."
What Allura gets right
Fiber cement as a category earns its reputation here in Whatcom County for good reason. It doesn't rot, it resists the moss and mildew that plague cedar and wood-composite siding in our wet winters, and it stands up to wind-driven rain far better than vinyl. Allura's boards meet the same basic fiber cement standard as other manufacturers in this space, and in a dry climate with an experienced crew, a well-installed Allura job can perform reasonably well for years.
Our issue isn't that Allura is a bad product on paper. It's that when we weigh manufacturer support, factory finish systems, and how a siding line actually gets serviced over 20-30 years in a marine climate like Lynden's, it doesn't hold up against what we can offer with James Hardie.
Where it falls short for our climate and our standards
Climate-engineered product lines
Whatcom County sits close enough to Puget Sound and the Strait of Georgia that homes here deal with a real mix of salt-laden air, long stretches of driving rain, and a moss season that can run most of the year on north-facing walls. James Hardie engineers separate product formulations for different climate zones — including an HZ10 line built specifically for cold, wet regions like ours — with moisture and freeze-thaw behavior tuned to what a Pacific Northwest wall assembly actually experiences. Allura's product line is not built around that same climate-zone engineering approach, which matters more here than it would in a mild, dry region.
Factory finish system
A big part of what makes fiber cement worth the investment is the factory-applied finish, not just the board underneath it. Hardie's ColorPlus finish is baked on in a controlled factory process and backed by its own dedicated finish warranty, separate from the substrate warranty. That two-part warranty structure is one of the reasons Hardie siding tends to hold its color and resist fading, chipping, and streaking better over time. Allura offers factory-finished options as well, but the finish warranty structure and track record aren't as deep or as widely proven in real-world Pacific Northwest installations, and that's not something we're willing to guess on for a homeowner's investment.
Regional availability and warranty support
James Hardie has a well-established distributor and installer network throughout Western Washington, which means consistent stock, predictable lead times, and a straightforward path if a warranty claim ever needs to be filed years down the road. Allura is stocked less consistently by regional suppliers, which can mean longer waits for exact color and profile matches on a repair or addition, and less certainty about how smoothly a warranty claim gets handled by the time it's actually needed.
Installer familiarity
Correct fiber cement installation is unforgiving — proper clearances, fastener patterns, flashing details, and caulking practices all matter, and mistakes don't show up as failures until years later, often as moisture damage behind the siding. We've built our crew's training, our details, and our warranty process entirely around one product line. Splitting that focus across multiple fiber cement brands means less depth of experience with any single one, and on a house that has to shed Lynden's rain for the next few decades, we'd rather have total familiarity with the product going on the wall.
Side-by-side, in plain terms
| Factor | Allura | James Hardie |
|---|---|---|
| Core material | Fiber cement | Fiber cement |
| Climate-specific engineering | General product line | Zone-specific formulations, including a cold/wet-climate line |
| Factory finish warranty | Available, less established locally | Dedicated finish warranty, well-documented track record |
| Regional stock and lead times | Limited local distribution | Established Western WA supply network |
| Our crew's installation experience | Minimal | Extensive, standardized |
Why we standardized on Hardie
We made a deliberate call to install one fiber cement product line and do it right, rather than offer several and spread our expertise thin. James Hardie's climate-matched HZ10 formulation, its ColorPlus factory finish and warranty structure, and its strong presence among Whatcom County suppliers and homeowners all point the same direction for a house that has to handle salt air, sideways rain, and months of moss pressure without drama. It's non-combustible, it holds its finish, and when something does need service years from now, the support system behind it is there.
