Blaine Siding Allura Isn't a Bad Product — It's Just Not the One We Put on Your House
If you've been shopping fiber cement siding for a home in Blaine or anywhere else in Whatcom County, you've probably run across Allura. It's a legitimate fiber cement manufacturer, it's been in the North American market for a long time under a few different names, and it's not junk. We want to be upfront about that before we explain why we don't install it.
Our company installs one fiber cement product line: James Hardie. That's not a marketing gimmick or a distributor kickback arrangement — it's a standard we set because of what we've seen happen to fiber cement siding on homes exposed to salt air, driving rain off the Strait of Georgia, and a moss season that in this part of Washington can run eight or nine months a year. This page walks through the real trade-offs, not vague brand-bashing.
What Allura Gets Right
Fiber cement as a category — whether it's Allura, Hardie, or another manufacturer — beats vinyl and wood on the fundamentals that matter in a marine climate: it doesn't burn, it doesn't warp in the rain, and it holds paint far longer than wood siding does. Allura's boards are manufactured using a Hatschek process similar to Hardie's, and the company has made real investments in matching common siding profiles — lap, shingle, panel — at a price point that's often a bit below Hardie's.
For a contractor working strictly on price, or for a homeowner whose budget is the deciding factor, Allura is a defensible choice. We're not going to tell you it falls apart the moment it's nailed up. It doesn't. The differences that matter to us show up over the 20-30 year ownership window, not in year one.
Where the Two Products Are Genuinely Similar
- Both are Portland cement, sand, and cellulose fiber composite boards — non-combustible, resistant to rot and insect damage
- Both are manufactured to meet ASTM C1186 / C1186M standards for fiber cement siding
- Both offer factory-primed and factory-finished color options
- Both require fiber-cement-rated fasteners, blades, and installation methods — this isn't a product you hand a general carpentry crew
Where We Part Ways: Factory Finish Consistency
James Hardie's ColorPlus finish is baked on in a controlled factory environment using a multi-coat process, and Hardie backs it with a separate 15-year finish warranty on top of the product warranty. Allura offers factory finishes as well, but the track record and warranty structure around that finish — particularly how it performs under years of coastal UV exposure and salt-laden moisture — is thinner in the field, simply because Hardie has been the dominant fiber cement brand in the Pacific Northwest for over two decades and Allura's regional footprint here is smaller.
That matters more in Blaine than in a drier inland market. Homes here sit close enough to the water that salt air is a constant low-grade stressor on any painted or coated exterior surface. A finish that's rated for "coastal exposure" in a lab is one thing; a finish with two decades of documented performance on homes fifteen minutes from the water in this specific climate is another. When we can't point to that track record for a product, we don't want to be the ones explaining the fade or chalking to a homeowner in year eight.
Where We Part Ways: Climate-Specific Product Engineering
Hardie builds and markets region-specific formulations — HZ5 and HZ10 lines engineered around freeze-thaw cycling and moisture exposure that vary by climate zone. Western Washington falls into a specific HZ designation, and Hardie's engineering documentation is built around performance in exactly this kind of wet, moderate-freeze coastal environment.
Allura doesn't offer that same tier of climate-zone-specific product engineering in its published specs. That doesn't mean an Allura board will fail here — plenty of fiber cement siding performs adequately in a wide range of climates without zone-specific tuning. But "adequately" isn't the bar we hold ourselves to when a homeowner is paying for a multi-decade exterior. We'd rather install the product that was specifically engineered for Whatcom County's rain load and humidity than one that wasn't.
Where We Part Ways: Warranty Structure and Transferability
This is the one that actually costs homeowners money down the road, and it's worth a table.
| Factor | James Hardie | Allura |
|---|---|---|
| Product warranty (typical) | Non-prorated, 30-year limited on most siding products | Limited warranty, varies by product line — check current terms carefully |
| Factory finish warranty | Separate 15-year ColorPlus finish warranty | Finish warranty terms vary and are less standardized across products |
| Transferability to new owner | Well-documented transfer process, widely recognized by real estate appraisers in this region | Transfer provisions exist but are less consistently recognized locally |
| Regional installer density | Deep network of trained installers and warranty-service contractors in western WA | Smaller regional network for warranty service and product matching |
That transferability line matters more than most homeowners expect. If you sell your home in Blaine within the warranty period — and a lot of people do, whether by plan or by circumstance — a well-documented, widely recognized warranty is something a buyer's agent and a home inspector will actually reference. A warranty that's technically real but unfamiliar to local real estate professionals doesn't carry the same weight at closing.
Where We Part Ways: Product Availability for Repairs and Matching
Ten or fifteen years from now, if a board gets cracked by a fallen branch or a delivery truck backs into a corner of the house, someone is going to need to source a matching replacement board — same profile, same reveal, same color. Hardie's product lines are stable and widely stocked by regional lumberyards and siding distributors throughout Washington. Allura's product availability and distributor network in this specific region is thinner, which can turn a simple repair into a delay or a color-match compromise.
We think about siding as a 30-year system, not a one-time installation. Repairability years down the line is part of that system, and it's a factor that's easy to overlook when you're comparing two products side by side in a showroom.
Installation Sensitivity: True of Both Products
To be fair to Allura, none of the above is about installation quality — it's about the product itself. Both Allura and Hardie fiber cement are unforgiving of bad installation practices. Improper fastening, missing kerf-cut weep gaps, insufficient clearance from grade or roofing, and skipped caulking at butt joints will cause problems with either brand, especially in a climate that sees the rainfall Blaine gets.
We standardized on one product in part so our crews build deep, repeated expertise in exactly how it behaves — its cut dust profile, its fastener pull-through tolerances, its factory-finish touch-up requirements — rather than splitting attention across multiple fiber cement systems with slightly different specs.
What Correct Fiber Cement Installation Requires, Regardless of Brand
- Minimum 6-8 inch clearance from siding bottom edge to grade, more in high-splash areas
- Weather-resistive barrier and properly flashed windows, doors, and penetrations installed first
- Fiber-cement-rated corrosion-resistant fasteners driven to manufacturer torque and placement specs
- Proper joint treatment — caulked and painted butt joints or engineered joint systems, not just butted boards
- Rainscreen or drainage gap in high-exposure coastal applications
- Field-cut edges primed or sealed before installation, especially on factory-finished boards
Why Hardie Is What We Actually Put on Homes
We land on James Hardie because, in this specific climate — salt air rolling in off the water, driving rain for a large chunk of the year, and moss and algae pressure that punishes any siding with weak finish durability — the combination of climate-zone engineering, factory finish track record, warranty structure, and regional support tips clearly in Hardie's favor. It's not that Allura would fail on your house. It's that when we're the ones putting our name behind a 30-year exterior investment, we want every variable working in the homeowner's favor, not just most of them.
That standardization also means our crews aren't guessing. Every fastener spec, every reveal measurement, every touch-up procedure is second nature because it's the only fiber cement system we run. That consistency shows up in the finished product.
What This Means for Your Project
If a contractor bidding your Blaine or Whatcom County siding job is offering Allura at a lower price than a Hardie quote, that's worth understanding rather than dismissing — but ask specifically about the finish warranty terms, the transferability language, and who locally stocks matching repair boards for that product line before you decide it's an apples-to-apples comparison. A lower bid on a different product isn't the same conversation as a lower bid on the same one.
We'd rather lose a job explaining honestly why we only install one product than install something we can't fully stand behind for the next three decades on your home.
