Blaine Siding Two Fiber Cement Brands, One Big Decision
If you've been comparing siding quotes around Blaine, you've probably heard two names come up: James Hardie and Allura. Both are fiber cement products, both are miles ahead of vinyl or untreated wood in terms of fire resistance and durability, and both will show up on a reputable contractor's short list. So why does this company only install one of them?
It's not because Allura is a bad product. It's a legitimate fiber cement siding with real advantages over vinyl and wood. But after years of installing and repairing siding along the Whatcom County coastline, we made a call to standardize on a single manufacturer's system — trim, panels, finish, fasteners, and warranty all engineered to work together — rather than mixing and matching based on whichever product happens to be cheaper on a given week. This page explains why James Hardie won that call.
What Allura Gets Right
Fair is fair. Allura fiber cement siding shares the same basic chemistry as Hardie: Portland cement, sand, and cellulose fiber, autoclaved into a dense, dimensionally stable board. That formula is what makes fiber cement non-combustible, resistant to woodpeckers and insects, and far more stable in wet climates than wood lap siding or engineered wood products like LP SmartSide. Allura's lap and panel profiles are competitively priced, its texture options are reasonable, and for a homeowner on a tight budget who still wants fiber cement over vinyl, it's a defensible middle-ground choice.
We're not going to tell you Allura falls apart in the rain or that it's a scam product — that wouldn't be honest, and it isn't true. The differences that matter are quieter than that: manufacturing consistency, finish technology, climate-specific engineering, and what happens five or fifteen years down the road when something needs attention.
Where the Products Really Diverge
Factory Finish
This is the single biggest practical difference for a coastal Whatcom County home. James Hardie's ColorPlus finish is baked on in a controlled factory environment using a multi-coat process specifically engineered to resist UV fading and hold up in wet, salt-exposed climates — and it comes with its own dedicated finish warranty, separate from the substrate warranty. Allura offers factory-finished options in some product lines, but the coating technology and the length of the finish warranty vary by line, and not every Allura product ships with the same factory-cured finish coverage that ColorPlus provides across Hardie's whole lineup.
Why does this matter here specifically? Blaine sits right on the water, and homes anywhere near Semiahmoo Bay or Drayton Harbor take on a steady dose of salt air on top of Pacific Northwest rain. A finish that's engineered and tested for that combination — rather than a general-purpose exterior coating — is the difference between repainting in year eight and repainting in year twenty.
Climate-Engineered Product Lines
James Hardie builds its siding in distinct product lines matched to regional "HardieZone" climate categories — HZ5 for the Pacific Northwest's wet, moderate-freeze conditions, HZ10 for hot, humid regions, and so on. The formulation, moisture resistance, and installation specs differ by zone. Allura does not offer the same tiered, region-specific engineering across its full catalog. That's not a knock on the product's basic performance — it's a difference in how deliberately each manufacturer designed for our specific weather.
Why Whatcom County's Climate Raises the Stakes
Siding decisions that might be a coin flip in a dry inland climate stop being a coin flip here. Blaine gets driving, wind-blown rain off the Strait of Georgia for a good chunk of the year, salt air working on every exposed fastener and finish, and a moss season that runs long on north-facing walls and anything shaded by fir and cedar cover. That combination punishes any weak point in a siding system — a finish that chalks early, a caulk joint that wasn't detailed to spec, a fastener that wasn't rated for coastal exposure.
We don't think that's a place to save money on the finish coat or gamble on a product line that wasn't specifically engineered for this climate. It's the reason we don't install primed spruce or cedar lap siding anymore either — beautiful when new, but high-maintenance in exactly the conditions Blaine throws at it year after year.
Warranty Fine Print: Read Before You Sign
Every fiber cement manufacturer offers a warranty, and on paper the numbers can look similar. The details are where they separate. James Hardie's warranty on most residential products is transferable to a subsequent homeowner (within a defined window and with proper registration), which matters for resale — an appraiser or buyer's inspector recognizes the Hardie name and the ColorPlus finish warranty as a documented asset, not just a sales claim.
Allura's warranty terms are worth reading closely product by product, particularly around finish coverage, labor reimbursement, and transferability. This isn't an accusation that Allura's warranty is deceptive — it's a reminder that "lifetime warranty" printed on a brochure and a warranty that actually pays out labor costs for a full siding replacement are two different things, for any manufacturer. Ask for the actual warranty document, not the summary page, before you decide.
Cost, Availability, and the Local Support Question
Allura siding typically prices a step below James Hardie on material cost alone, which is real money on a full re-side. But material cost is only part of the picture. Hardie's dominant market share in the Pacific Northwest means trim, soffit, fascia, and touch-up paint are almost always in stock locally, color-matched batches are easier to source if you need a repair years later, and certified installers are more common — which affects both your labor quotes and how easy it is to find someone qualified to service the siding down the line.
| Factor | James Hardie | Allura |
|---|---|---|
| Material cost | Higher upfront | Typically lower upfront |
| Factory finish | ColorPlus, climate-tested, separate finish warranty | Varies by product line and finish option |
| Climate-specific engineering | HardieZone system (HZ5 for our region) | Not tiered by region across the full catalog |
| Warranty transferability | Transferable to next owner (with registration) | Check specific product warranty terms |
| Local parts/color-match availability | Widely stocked in the Pacific Northwest | More limited, varies by supplier |
| Certified installer network | Larger pool regionally | Smaller pool regionally |
None of this means Allura is a poor product in isolation. It means that once you factor in long-term serviceability — not just the sticker price on installation day — the gap narrows or disappears for most homeowners planning to stay in their home more than a few years.
A Side-by-Side Look at the Real Trade-Off
Boiled down, the choice usually comes down to this: Allura can save you money today. James Hardie is engineered, finished, and warrantied specifically to reduce what you'll spend on maintenance, touch-up, and eventual replacement over the next twenty to thirty years in a wet, salt-air coastal climate. For a rental property or a short-term hold, that math might favor the lower upfront cost. For a home you plan to live in and eventually sell in Blaine or anywhere along this stretch of Whatcom County, the finish durability and warranty transferability tend to matter more.
What We Tell Every Homeowner Who Asks
We standardized on James Hardie for the same reason we don't install LP SmartSide, vinyl, Cemplank, primed spruce, or cedar: we'd rather install one system well, understand its installation requirements in depth, stand behind a warranty we can actually explain in plain language, and know that replacement parts will be available in ten years — than offer a menu of products we can only support at a surface level. That's a business decision as much as a technical one, and we think it's the more honest way to run a siding company.
If a lower-cost fiber cement product is genuinely the right call for your situation — a rental, a flip, a tight budget with a shorter time horizon — we'll say so plainly rather than talk you into something you don't need. But for a primary residence exposed to Blaine's salt air and rain, we install Hardie because it's what we're willing to warranty our labor against.
Questions Worth Asking Before You Choose a Product
- Does the quoted product have a factory-applied finish, and is the finish warranty separate from the substrate warranty?
- Is the specific product line engineered for a wet, coastal climate zone, or is it a general-purpose formulation?
- Is the warranty transferable to a future homeowner, and what does it actually cover — materials only, or labor too?
- Can the installer show you a job they finished at least five years ago that's held up in similar coastal conditions?
- Are replacement panels and color-matched trim realistically available locally if a repair is ever needed?
- Is the installer certified or factory-trained on the specific product being quoted, not just "experienced with fiber cement" in general?
