Anacortes Exterior Allura Isn't a Bad Product — It's Just Not the One We Put Our Name Behind
If you've priced out fiber cement siding for a home in Anacortes, you've probably run into Allura as an option, usually pitched as a lower-cost alternative to James Hardie. It's worth saying plainly: Allura is a legitimate fiber cement product, not a knockoff. It's cement, sand, and cellulose fiber pressed and cured the same basic way Hardie's boards are, and it will outperform vinyl or untreated wood on durability in most respects. We don't install it, but that's a decision about fit for our climate and our standards, not a claim that it's junk.
Why the Distinction Matters on Fidalgo Island
Anacortes sits right on the water, and that changes what a siding product has to deal with day in and day out. Salt air accelerates corrosion on fasteners and trim hardware. Driving rain off Rosario Strait and the Sound pushes moisture sideways into seams and butt joints, not just straight down. And Skagit County's long, gray moss season means algae and moss growth on north-facing walls and anything shaded by trees is a near-certainty, not a maybe. Any siding installed here needs a finish system and an engineering spec built for sustained wet exposure, not just resistance to an occasional storm.
Where the Two Products Actually Differ
The differences that matter for a coastal Skagit County home come down to a handful of practical points:
| Factor | What it means in practice |
|---|---|
| Factory finish | Hardie's ColorPlus is a baked-on, multi-coat finish applied and cured under factory conditions with a documented finish warranty. Allura's finish options vary by line and haven't built the same long track record in the Pacific Northwest specifically. |
| Climate-specific engineering | Hardie ships different HZ5/HZ10 formulations tuned to freeze-thaw and moisture zones. That kind of region-specific engineering is a big part of why we standardized on it for a marine climate. |
| Regional distribution and support | Hardie has deep, established distribution and installer training infrastructure in Western Washington. That matters when a board gets damaged and needs an exact-match replacement two years from now. |
| Warranty structure | Hardie's transferable warranty terms are well-documented and widely honored by installers and inspectors alike, which carries real weight at resale. |
The Real Trade-Off: Cost vs. Long-Term Certainty
Allura is often a few dollars a square foot cheaper installed, and for some homeowners in some markets, that math works out fine. Our issue isn't that Allura fails — it's that we can't verify the same multi-decade performance record in a marine, high-moss environment that we can with Hardie, and we're not willing to install something on your home in Anacortes that we can't stand behind twenty years out. When moisture gets into a seam on a house that sits fifty feet from saltwater, the margin for error installation gets thinner, and we'd rather build in that margin with a product and finish system that's proven itself here specifically.
What This Looks Like in Practice
A few concrete things separate the products in the field:
- Touch-up and matching: Hardie's ColorPlus touch-up products and replacement plank availability are consistent across the region, so a repair five years from now looks right.
- Cut-edge treatment: Both products require sealing at field cuts to prevent moisture wicking, but Hardie's documentation and installer training around this is what our crews are certified to and have executed for years.
- Moss and algae resistance on shaded walls: the factory finish and substrate density affect how well a board sheds growth on the north side of a house tucked under fir trees, which describes a lot of lots around here.
- Insurance and inspection familiarity: appraisers, inspectors, and insurance underwriters in this region are simply more familiar with Hardie, which can matter at resale or claims time.
Why We Standardized on Hardie Instead
We made a decision a while back to install James Hardie exclusively — no vinyl, no LP SmartSide, no Cemplank, no Allura, no primed spruce or cedar — because it lets us stand fully behind every job. Hardie is non-combustible, backed by a strong transferable warranty, and available in HZ product lines specifically engineered for wet coastal climates like ours. The ColorPlus factory finish holds up to salt air and repeated wet-dry cycles better than field-applied or lighter factory finishes, and the local supply chain means repairs and matches are straightforward for as long as you own the home. Standardizing on one product also means our crews aren't relearning installation quirks between five different siding systems — they install Hardie, correctly, every time.
