Bellingham Exterior Allura Isn't a Bad Product — It's Just Not the One We Stand Behind
Homeowners in Bellingham sometimes come to us with a quote in hand from another contractor that specs Allura fiber cement siding, and they want to know why our bid looks different. It's a fair question, and it deserves a straight answer instead of a sales pitch. Allura is a real fiber cement siding product, manufactured to compete directly with James Hardie, and it isn't junk. But after years of installing and repairing siding across Whatcom County, we made the call to install James Hardie exclusively, and we think you should understand why before you sign a contract with anyone.
This isn't about trashing a competitor's product. It's about being honest with you regarding the trade-offs we've seen in the field, particularly in a climate like ours — salt air off Bellingham Bay, driving rain for most of the fall and winter, and a moss season that seems to stretch a little longer every year.
What Allura Fiber Cement Actually Is
Allura siding is a cellulose fiber-reinforced cement product, similar in basic composition to James Hardie's boards. It's cut, nailed, and painted using largely the same techniques, and it carries a Class A fire rating and resistance to rot and insects, same as any quality fiber cement. For a lot of markets, it's a perfectly reasonable siding choice, and plenty of contractors install it well.
Where it separates from Hardie is in the specifics: the factory finish system, the regional engineering of the boards, the depth of the warranty, and — frankly — the consistency we've experienced with product availability and matched trim components when a repair or an addition comes up years down the road.
What Allura Gets Right
We'll give credit where it's due:
- Fire resistance. Like all fiber cement, Allura is non-combustible, which matters in wildfire-adjacent regions and simply for peace of mind.
- Durability against rot and pests. It won't feed carpenter ants or absorb moisture the way wood-based siding does.
- Price point. Allura is often quoted a bit below James Hardie, which makes it attractive on paper for budget-conscious projects.
- Basic performance. Installed correctly, it holds paint and resists warping far better than vinyl, LP SmartSide, or primed wood siding.
If a product is competent at the fundamentals, why not install it? The answer comes down to what happens after the crew leaves — the finish system, the warranty you can actually collect on, and how the product behaves under sustained exposure to Pacific Northwest weather.
Why We Don't Put Allura on Whatcom County Homes
The Finish System Is the Real Differentiator
Fiber cement siding fails or succeeds based almost entirely on its factory finish, not the substrate underneath. James Hardie's ColorPlus finish is a baked-on, multi-coat process engineered specifically to hold color and resist fading, chipping, and moisture intrusion at the board level, backed by its own dedicated finish warranty separate from the product warranty. Allura's factory finish options exist, but the coverage and track record we've seen locally don't match up, and site-painted or field-touched fiber cement is exactly where we've watched siding jobs go wrong over the long haul — caulk lines failing, color mismatches at repairs, and moisture creeping in at cut edges that weren't properly sealed.
Bellingham's Climate Is Unforgiving of Shortcuts
Whatcom County isn't a gentle climate for exterior building products. We get sustained, driving rain off the Strait of Georgia for months at a time, salt-laden air near the bay and the waterfront neighborhoods, and shaded, damp conditions inland that keep moss and algae established on north-facing walls almost year-round. Every seam, cut edge, and fastener point on a fiber cement installation is a potential entry point for moisture if the product and the install aren't both built for it. James Hardie engineers regional HZ5 product lines specifically for climates like ours, with moisture management built into the plank profile and installation specs. We haven't seen that same level of regional engineering, documentation, or long-term local track record from Allura.
Warranty Structure and What You Can Actually Collect
Every siding manufacturer publishes an impressive-sounding warranty. What matters is what's actually transferable, what's prorated, and how straightforward the claims process is if a problem shows up in year eight instead of year one. James Hardie's warranty terms are well-documented, widely honored, and transferable to a new owner if you sell your home — which matters a lot in a market like Bellingham's, where buyers and their inspectors increasingly ask what siding brand is on the house. We're not going to put our name behind an installation backed by a warranty structure we can't stand behind with the same confidence.
Long-Term Parts and Repair Availability
Siding takes decades to run its course, and at some point you'll likely need a repair — a tree branch, a delivery truck, a remodel that requires tying in new material. When that happens, the ease of sourcing matched trim, corner boards, and plank profiles matters. We've had a more consistent experience keeping Hardie profiles and colors available and matched than we have with other fiber cement brands, and that's a real cost we factor in on your behalf, not just ours.
Allura vs. James Hardie: The Honest Comparison
| Factor | Allura Fiber Cement | James Hardie Fiber Cement |
|---|---|---|
| Core material | Cellulose fiber-reinforced cement | Cellulose fiber-reinforced cement |
| Fire rating | Non-combustible, Class A | Non-combustible, Class A |
| Factory finish | Available, less established track record locally | ColorPlus baked-on finish with separate finish warranty |
| Regional climate engineering | Standard product line | HZ5 line engineered for Pacific Northwest moisture exposure |
| Warranty transferability | Varies by product line | Transferable to subsequent owners |
| Upfront cost | Typically somewhat lower | Moderate premium, reflected in finish and warranty |
| Long-term parts matching | Less consistent regionally, in our experience | Widely stocked and matched by regional distributors |
Installation Sensitivity Matters More Here Than the Brand
We'll be honest about something else too: a poorly installed James Hardie job will fail just as fast as a poorly installed Allura job. Fiber cement siding of any brand depends on correct fastening patterns, proper gapping and caulking at joints, flashing details at windows and rooflines, and clearance from grade and hardscaping to keep moisture from wicking up into the bottom of the boards. Bellingham's rain volume punishes shortcuts on any siding brand. Part of why we standardized on one manufacturer is so our crews build deep, repeated expertise installing to a single spec, rather than switching between products and specs from job to job.
Why We Standardized on James Hardie Instead
We didn't pick James Hardie because it's the most recognizable name in fiber cement. We picked it because, over repeated installations across Whatcom County's mix of coastal, in-town, and inland properties, it's given us the most consistent combination of:
- A factory finish system with a strong, well-documented warranty
- Product lines engineered for high-moisture, marine-influenced climates
- Reliable long-term availability of matching trim and repair material
- A transferable warranty that holds up at resale
- A single install specification our crews can execute the same way, every time
That consistency is what lets us stand behind the work fifteen and twenty years after we finish a project, not just on install day.
What This Means for Your Project
If you're comparing quotes and one contractor is proposing Allura, LP SmartSide, vinyl, or another alternative, that doesn't automatically mean it's a bad choice for your budget or situation. It means you should ask the right questions before deciding. Before hiring anyone for a siding project in Bellingham or elsewhere in Whatcom County, ask:
- What is the manufacturer's finish warranty, specifically, and is it transferable if you sell the home?
- Is the product line engineered for coastal or high-rain climates, or is it a general-purpose spec?
- Will matching trim and repair material realistically be available in ten or twenty years?
- What installation certification or training does the crew have on this specific product?
- What does the labor warranty cover, separate from the material warranty?
Those questions matter more than the brand name on the quote, and any honest contractor should be able to answer them without hesitation.
Our Honest Bottom Line
Allura is a legitimate fiber cement product, and we're not here to tell you it will fail on your house. We're telling you why we, as a company that installs siding every week in this exact climate, chose to specialize in one manufacturer's system rather than juggle several. That decision is about the finish, the warranty, the regional engineering, and the long-term serviceability — the parts of a siding job that matter most after the truck pulls away and the first few wet Bellingham winters roll through.
