Blaine Siding Allura makes a legitimate fiber cement siding product, and we want to be upfront about that before explaining anything else. It's cement, sand, and cellulose fiber, cured the same general way as most fiber cement on the market, and it shares the core advantages of the category: it doesn't rot, it resists insects, and it holds paint far better than wood. If a homeowner in Blaine already has Allura siding on their house, it isn't a product we'd tell them to panic about.
That said, when a homeowner asks us to install new siding, we install James Hardie exclusively. Allura is one of the products we don't install, and we think homeowners deserve a straight answer about why — not vague marketing language, just the practical reasons.
Where Allura gets fiber cement right
Fiber cement as a category earned its reputation because it solves real problems that wood and vinyl siding have in a marine climate like ours. Blaine sits right on the water, and between salt air rolling in off the Strait of Georgia, driving rain through the fall and winter, and a moss season that seems to run most of the year in Whatcom County, siding here takes a beating that drier inland regions never see. Fiber cement's rigidity, its resistance to moisture-driven rot, and its ability to hold a factory finish are exactly what this climate calls for. Allura checks those boxes at a basic level, the same as any fiber cement product does.
Why we don't install it anyway
Our reservations about Allura aren't about whether the base material is "fake" fiber cement — it isn't. They come down to three practical things we weigh on every home: factory finish quality, warranty structure, and regional support.
Factory finish and long-term color hold
A big part of what makes fiber cement worth the cost is the factory-applied finish, because a finish baked on under controlled conditions holds up dramatically better than anything painted on site later. James Hardie's ColorPlus finish is engineered specifically around resisting fade and chipping through repeated wet-dry cycles, which is exactly the cycle Blaine's climate puts siding through — rain soaking the wall, then drying, then rain again, month after month. Allura offers finish options too, but the track record and the specific engineering behind Hardie's factory finish for wet coastal climates is what gave us confidence to standardize on it. We didn't want to guess on a 30-year exterior.
Product lines engineered for the climate zone
James Hardie builds region-specific HZ5 product formulations meant for areas that see a lot of moisture, which is a direct match for northwest Washington. That's a specific engineering response to freeze-thaw and moisture exposure, not a generic one-size-fits-all board. We didn't find the same depth of climate-zone-specific engineering documentation behind Allura's line, and on a coastal property in Whatcom County, that's not a detail we're willing to treat as optional.
Warranty and what happens after we're done
A siding warranty is only as good as the paper trail and support behind it when a homeowner needs to use it 12 or 20 years down the road. Hardie's transferable warranty structure and its long-established network of installers and distributors gave us a warranty story we could stand behind with confidence when we tell a homeowner what happens if something goes wrong. That same level of established, long-term warranty backing and installer network wasn't something we could commit to the same way with Allura.
Installation sensitivity matters more than people expect
Fiber cement in general is not a forgiving material to install poorly — cut edges, fastener patterns, and caulking details all matter enormously to how the siding performs over time, and that's true of every fiber cement brand, Hardie included. But when we standardized on one product line, part of the reason was so our crews could specialize deeply in one system's install requirements rather than splitting attention across multiple brands with different trim details, flashing requirements, and finish touch-up products. That specialization is part of what protects a home against the driving rain and salt exposure this area sees.
What this means if you already have Allura siding
If your home currently has Allura siding, this isn't a reason for alarm. It's a real fiber cement product and it will generally perform the way fiber cement is expected to perform, provided it was installed correctly and the finish is being maintained. If you're noticing chalking, finish wear, or edge issues, we're glad to take a look and give you an honest read on condition — not a scare tactic to sell a full replacement.
Why we standardized on Hardie instead
We made the call to install James Hardie exclusively because, on balance, it gave us the combination we wanted for homes on this stretch of the Washington coast: a factory finish engineered around wet-dry cycling, a product line built for high-moisture regions, and a warranty and support structure we could explain to a homeowner with a straight face. Salt air and a long wet season don't leave much room for guessing on siding, and Hardie is the product we've found holds up to that standard.
