Ferndale Siding A Legitimate Product, Just Not Our Standard
Allura is a real fiber cement product, not a knockoff. It's made from the same basic recipe as James Hardie: Portland cement, sand, and cellulose fibers, cured into a board that won't rot, won't feed termites, and won't burn the way wood siding will. If a homeowner in Ferndale already has Allura on their house and it was installed correctly, we're not going to tell them it's failing or that they need to rip it off tomorrow. That's not an honest claim, and we don't make those.
What we will say is why our own crews don't install it. After years of installing fiber cement siding across Whatcom County, we standardized on one manufacturer's system, and it's James Hardie. Here's the reasoning, laid out plainly.
Where the Trade-offs Show Up
Fiber cement performs differently depending on the finish that's baked into it at the factory versus what gets applied on site. This matters more here than in a lot of markets, because Ferndale sits close enough to the Salish Sea that homes deal with salt-laden air, long stretches of driving rain off the water, and a moss and algae season that can run most of the year on north-facing walls. A siding product's finish is doing real work in this climate, not just sitting there looking good on install day.
- Factory finish depth. James Hardie's ColorPlus finish is a multi-coat, baked-on process backed by a dedicated finish warranty that's separate from the substrate warranty. Some Allura product lines lean more heavily on primed boards that still need field-applied paint. Field-applied finishes are only as good as the weather conditions and prep work on the day they're sprayed or rolled, and in a county where rain can show up on short notice, that's a real variable.
- Warranty structure. Both manufacturers offer warranties, but the terms, coverage, and transferability differ between them. Hardie's warranty documentation and claims process are ones our crews and our customers have been through many times over. We know exactly what's covered, for how long, and what happens if a homeowner sells the house. Splitting our installs across two manufacturers means splitting that institutional knowledge too, and that's a cost we pass on to nobody but ourselves if we let it happen.
- Local supply and color consistency. Hardie has a well-established distribution network through this part of the Pacific Northwest, which means predictable lead times and consistent color-matched trim, soffit, and accessory pieces for repairs or additions down the road. When a homeowner calls us five years after an install because a section got damaged, we want to be confident we can match it without a special order or a color that's drifted.
- Moss and algae resistance in practice. A long wet season means anything on the north and west walls of a house is going to see sustained moisture and shade. The performance of any fiber cement product in those conditions comes down to the finish holding its seal and shedding water at the lap joints and butt seams. We've built our installation details — flashing, gapping, caulking — around Hardie's specific engineering guidance for this region, and we're not interested in re-learning those details for a second product line just to offer more options.
It's About Standardizing, Not Disqualifying
None of this means Allura is a bad product. It means that running one fiber cement system, start to finish, lets our crews get genuinely expert at one set of installation specs instead of reasonably good at two. Fiber cement siding is unforgiving of sloppy installation regardless of brand — improper fastening, missing clearances, or bad caulking will cause problems whether the board says Hardie or Allura on the back. We'd rather put our training, our warranty relationships, and our supply chain behind one manufacturer we know cold than spread that expertise thin.
Why We Install James Hardie Instead
James Hardie builds specific product lines engineered for different climate zones, and the HZ10 line used in this region accounts for the moisture load Whatcom County sees. Combine that with the ColorPlus factory finish, a warranty that's transferable to a new homeowner, and a distribution network that keeps materials and matching trim on hand locally, and it's the system we're willing to put our name behind. It's noncombustible, it holds its finish through the rainy months, and when it's installed to spec, it's built to last for decades on a coastal Whatcom County home.
