Whatcom County Homeowners in Bellingham, Ferndale, Lynden, and across Whatcom County often ask why we don't offer Allura fiber cement siding as an option alongside James Hardie. It's a fair question — Allura is a real fiber cement product, not a cheap imitation, and on paper the two look similar. This page explains what Allura gets right, where the differences actually matter, and why we made the call to install James Hardie exclusively on every job we take.
What Allura Gets Right
Allura is fiber cement, made from the same basic recipe as most products in this category: Portland cement, sand, and cellulose fibers, cured into a dense, non-combustible board. That puts it well ahead of vinyl siding on durability and fire resistance, and it holds paint and moisture better than primed wood or engineered wood products like LP SmartSide. If a homeowner is comparing Allura to vinyl or cedar, Allura is the more serious product. We're not going to pretend otherwise.
Where the Differences Show Up
The gap between Allura and James Hardie isn't in the raw material — it's in manufacturing consistency, climate engineering, and what happens after installation when a problem shows up. In a marine climate like ours, those details matter more than they would somewhere dry and mild.
Factory Finish Consistency
James Hardie's ColorPlus finish is baked on in a controlled factory process with a specific warranty attached to the finish itself, separate from the substrate. We've found that finish consistency — batch to batch, order to order — is more reliable with Hardie, which matters a lot when a homeowner needs to match siding on an addition or repair a few years down the road. Whatcom County's driving rain and long moss season are hard on any exterior finish; a coating that ages evenly and doesn't chalk or fade unevenly saves homeowners from a patchwork look over time.
Climate-Zone Engineering
James Hardie builds regional HZ product lines engineered for specific climate exposure — moisture cycling, freeze-thaw, and humidity are all factored into the formulation for the zone a home sits in. Whatcom County's salt air off Bellingham Bay and the Strait of Georgia, combined with near-constant winter dampness, put real stress on any cladding material's moisture management over a 20-30 year service life. We wanted a product line built around that reality, not a general-purpose board.
Warranty Structure and Claims Support
This is the practical issue that pushed us toward a single-manufacturer standard. James Hardie's transferable warranty is well established, and because we install it exclusively, we know the process, the documentation requirements, and the manufacturer's regional support cold. Splitting our crews and our warranty knowledge across two fiber cement brands means being an expert in neither. If something needs a warranty claim ten or fifteen years from now, we want to already know exactly how that process works — not be relearning it for a product we installed on one job in 2019.
Installation Sensitivity
Fiber cement, generally, is unforgiving of shortcuts — improper fastening, wrong caulk, poor flashing detail, or gaps at butt joints will cause problems no matter whose name is on the board. Allura and Hardie both require correct installation to perform. The difference is that we've built our entire crew training, our flashing details, and our quality checklist around one product system. That specialization is part of what keeps callbacks low. Running two systems in parallel would mean diluting that expertise.
| Factor | Allura | James Hardie |
|---|---|---|
| Material | Fiber cement | Fiber cement |
| Fire resistance | Non-combustible | Non-combustible |
| Factory finish | Coating available | ColorPlus, factory-cured with dedicated finish warranty |
| Climate-specific lines | General product range | Regional HZ formulations |
| Our crew expertise | Not installed by us | Standardized, single-system training |
Why We Standardized on One Product
A contractor who installs three or four different siding brands is spreading crew training, warranty knowledge, and flashing detail across all of them. We decided it was better to go deep on one system — James Hardie — and know it thoroughly, from the fastening schedule to the finish warranty paperwork, than to be moderately familiar with several. For a homeowner, that specialization shows up as fewer callbacks, a finish that holds up evenly over the moss season, and a warranty process we can actually walk you through because we've done it before.
Allura is a legitimate fiber cement product, and we understand why some homeowners have it on their list. We simply chose to put our training, our crews, and our reputation behind one manufacturer whose climate-specific engineering and finish warranty match what Whatcom County's salt air and driving rain demand year after year.
