Bellingham Homeowners researching fiber cement siding in Whatcom County eventually run into the name Allura. It's a legitimate fiber cement product, and on paper it looks like a reasonable alternative to James Hardie. We get asked about it often enough that we want to explain, plainly, why we don't install it — and why every fiber cement job we take on in Bellingham goes out under the James Hardie name instead.
This isn't a takedown of Allura. It's fiber cement, which means it shares the same basic advantages over wood and vinyl: it doesn't rot, it resists pests, and it holds paint better than most alternatives. Our decision isn't about the raw material being bad. It's about the full package around that material — the finish system, the climate engineering, the warranty terms, and what happens when a homeowner needs a repair or a color match five, ten, or twenty years down the road.
What Allura Gets Right
To be fair to the product: Allura is manufactured from the same core recipe as most fiber cement — Portland cement, sand, and cellulose fiber, cured under pressure. That composition is what makes fiber cement siding fire-resistant, dimensionally stable, and far more durable than wood lap siding or engineered wood products in a wet Pacific Northwest climate. Compared to vinyl, it doesn't warp in the sun or crack in a hard freeze. Compared to primed spruce or cedar, it doesn't need the same level of ongoing maintenance to keep moisture out.
If a homeowner in Bellingham has already installed Allura and is asking whether it needs to be torn off, the honest answer is usually no — properly installed fiber cement, regardless of brand, performs reasonably well here. Our concerns are about what we can stand behind as installers going forward, not about condemning what's already on a wall.
Why We Don't Put Our Name on It
Factory Finish Is Where Siding Actually Fails First
In our experience, siding failures almost never start with the cement board itself — they start at the finish. Paint that chalks, fades unevenly, or peels at the seams is the number-one complaint we hear about older fiber cement installs. James Hardie's ColorPlus finish is a baked-on, multi-coat factory process backed by its own dedicated warranty and a defined touch-up and color-match program that's been in the field long enough for us to trust it in this climate. We haven't seen the same depth of long-term, region-specific finish data or the same breadth of matched touch-up and trim products from Allura's finish line, and we're not willing to guess with a homeowner's siding.
Climate Engineering, Not Just a Climate Claim
Bellingham sits in a specific bind: salt air off Bellingham Bay and the Salish Sea, driving winter rain off the Sound, and a long moss season that runs from fall through spring on anything shaded or north-facing. Siding here needs to shed water fast, resist salt-driven corrosion at the fasteners and trim, and not give moss a foothold at the joints. James Hardie engineers its HZ5 product line specifically for climate zones like ours — moisture exposure, freeze-thaw cycling, and coastal conditions all factor into the board formulation and installation specs. We have not found an equivalent, climate-zone-specific engineering commitment from Allura for this market, and given what salt air and a wet Whatcom County winter do to a poorly matched product, that's not a detail we're willing to treat as interchangeable.
Warranty Structure
Both brands offer warranties, but the structure matters more than the headline number. James Hardie's warranty on its siding is long-term, transferable to a new homeowner if the house sells, and not prorated the way many building product warranties are — meaning coverage doesn't quietly shrink year over year. We've reviewed Allura's published warranty terms and found the coverage structure less favorable to the homeowner over the life of the product, particularly around proration and what's required to keep the warranty valid. When we're the ones a homeowner calls if something goes wrong, we want the manufacturer's warranty behind us to actually hold up.
Regional Supply and Repair Support
This is the practical issue that matters most once a house is finished. James Hardie is the dominant fiber cement brand in the Pacific Northwest, which means matching trim boards, soffit, and touch-up paint is straightforward at local distributors years after the original install — whether for storm damage, a remodel, or a homeowner adding a garage that needs to match the house. Allura has a much thinner distribution and installer footprint in this region. If a board gets cracked by a falling branch in a windstorm five years from now, sourcing an exact match and finding a crew that regularly works with the product becomes a real problem. We'd rather not set a homeowner up for that headache.
Allura vs. James Hardie: The Honest Comparison
| Factor | Allura Fiber Cement | James Hardie Fiber Cement |
|---|---|---|
| Core material | Cement, sand, cellulose fiber | Cement, sand, cellulose fiber |
| Factory finish | Factory-applied paint program | ColorPlus baked-on, multi-coat finish with dedicated touch-up system |
| Climate-zone engineering | General product line | HardieZone HZ5 formulated for wet, coastal Pacific Northwest conditions |
| Warranty structure | Coverage terms include proration provisions | Long-term, transferable, non-prorated on the substrate |
| PNW distribution / repair matching | Limited regional stock and installer base | Widely stocked; trim, soffit, and touch-up readily matched locally |
| Fire and pest resistance | Non-combustible, pest-resistant | Non-combustible, pest-resistant |
Why We Standardized on One Manufacturer
Part of this decision is about installation quality, not just product specs. Fiber cement siding is unforgiving of installation shortcuts — improper fastening, wrong nail placement, insufficient gapping at butt joints, or poor flashing detail will cause problems regardless of brand. By installing exclusively James Hardie, our crews work to one set of manufacturer specifications, one set of fastening and clearance requirements, and one flashing and water-management standard on every job. That consistency is how we keep our own workmanship warranty meaningful. Splitting our crews' expertise across multiple fiber cement brands with different installation quirks increases the odds of a mistake — and on a house exposed to Whatcom County's driving rain for nine months of the year, installation mistakes are exactly where water gets in.
What This Means If You Already Have Allura Siding
If your home currently has Allura siding and it's performing well — tight joints, intact paint, no soft spots — there's usually no reason to replace it early. We can still service trim, gutters, and flashing details around it. The situation changes if you're seeing paint failure, cracking at fastener points, or moisture staining, especially on north- or west-facing walls that take the brunt of coastal weather. At that point it's worth an honest inspection to figure out whether the issue is a finish problem, an installation problem, or just normal wear.
Signs Worth Getting Looked At
- Chalking, fading, or peeling paint, particularly on shaded or north-facing elevations
- Visible cracking at butt joints or around fasteners
- Dark staining or moss buildup concentrated at seams rather than spread evenly
- Soft or spongy board edges near ground level or under downspouts
- Gaps opening up at trim and corner boards after a few winters
What We Install Instead
Every fiber cement job we do in Bellingham and the surrounding county goes out as James Hardie — HardiePlank lap siding, HardiePanel, or HardieTrim, depending on the house, finished with ColorPlus factory paint. We chose one manufacturer on purpose so we can guarantee our installation practices, back our workmanship with a warranty that actually pairs with the manufacturer's coverage, and make sure that whatever we put on a house today can still be matched and repaired twenty years from now by whoever is doing exterior work in this region at that point.
Questions to Ask Before Choosing Any Fiber Cement Product
- Is the factory finish warranted separately from the board, and for how long?
- Is the warranty prorated, and does it transfer to a future homeowner?
- Is the product engineered for a specific climate zone, or is it a general-purpose formulation?
- Can local suppliers stock matching trim, soffit, and touch-up paint five or ten years from now?
- How many local crews are certified or experienced with this specific brand's installation requirements?
