Bellingham Siding A Fair Look at Allura Fiber Cement
Allura makes a legitimate fiber cement siding product, and we want to be upfront about that. It's cement, sand, and cellulose fiber pressed and cured the same general way Hardie board is made, and it holds up better than vinyl or untreated wood in a lot of respects. We're not installing it, but that's not because we think it's junk. It comes down to a handful of practical trade-offs that matter more here on the water in Bellingham than they might somewhere drier and calmer.
What Allura Gets Right
Fiber cement as a category is a good call for the Pacific Northwest. It doesn't rot, it resists pests, and it's non-combustible — all real advantages over cedar or primed spruce siding. Allura's boards are dimensionally stable and priced competitively, and for a lot of markets that's a reasonable siding choice. If someone tells you fiber cement siding is a smart upgrade over wood or vinyl, they're not wrong, regardless of brand.
Where It Falls Short of Our Standard
Our concerns with Allura aren't about the raw material — they're about the finish system and the support behind it once the siding is on the wall.
- Factory finish consistency. Hardie's ColorPlus finish is baked on in a controlled factory process with a dedicated finish warranty. Allura's finish options and coating processes have shifted over the years and vary more by product line, which makes it harder to guarantee a uniform, long-term finish across an entire house — especially on a home that's going to spend twenty-plus years taking on salt air off Bellingham Bay.
- Moisture behavior at the coast. Fiber cement is only as good as the water management behind and around it. Whatcom County gets driving rain off the Strait of Georgia and long stretches of damp, low-sun weather where moss and algae take hold on north-facing walls. Every fiber cement product needs correct flashing, gapping, and caulking to perform, but the specific installation tolerances, touch-up paint matching, and manufacturer guidance differ between Allura and Hardie. We standardized our crews, our tools, and our detailing on one system so every install gets the same scrutiny — mixing systems increases the chance something falls through the cracks.
- Warranty structure and transferability. Hardie's warranty terms — including how they transfer to a new owner — are something we can explain to a homeowner with total confidence because we install it exclusively and see how claims get handled. We didn't want to sell a warranty we couldn't stand behind with the same depth of experience.
- Repair and batch matching down the road. If a board gets cracked by a falling branch in a windstorm five years from now, matching color and texture is far easier when your installer has a deep, current relationship with a single manufacturer's product lines. Spreading our inventory and expertise across multiple fiber cement brands would make that harder for every customer, not easier.
Why the Coast Makes This Decision Sharper
None of this is theoretical for a house in Bellingham. Homes near the water deal with salt-laden air that accelerates finish breakdown on anything less than a fully engineered coating system. The long moss season here — often six or seven damp months a year — means north and shaded walls need siding that resists moisture intrusion at every seam, not just siding that's technically rated for it. And Whatcom County's driving rain, especially in fall and winter storms, tests flashing and caulking details on every wall elevation, not just the exposed ones. We'd rather narrow our focus to one product system we can install, warranty, and repair with total consistency than offer a menu of fiber cement brands and dilute our expertise across all of them.
What We Install Instead
We put James Hardie fiber cement on every home we side, using their HZ5 climate-engineered product line built for wet coastal regions like ours. It comes with a factory-applied ColorPlus finish backed by its own finish warranty, a substrate that's cured specifically for high-moisture environments, and a strong, transferable product warranty. Because it's the only fiber cement system our crews work with, our installation details, caulking practices, and flashing methods are dialed in around this one product — not split across several.
The Bottom Line
Allura is a real fiber cement product with real merits, and we're not here to tell you it fails on a job site. We simply made a call, based on finish consistency, warranty depth, and long-term repair support, to install one system and do it right every time rather than offer several and do each one adequately. On a coastal Whatcom County home dealing with salt air, sideways rain, and months of moss pressure, we think that focus matters.
