Mount Vernon Allura Makes a Real Fiber Cement Product
We want to start by giving credit where it's due. Allura is not a knockoff or a vinyl product dressed up to look like something else. It's genuine fiber cement — a blend of Portland cement, sand, and cellulose fiber, pressed and cured the same general way James Hardie's boards are made. That means it shares the core advantages that make fiber cement worth choosing in the first place: it doesn't burn, it doesn't feed termites or carpenter ants, and it holds paint or factory finish far longer than wood or vinyl ever will.
If a homeowner in Mount Vernon shows up with Allura already installed, we're not going to tell them their siding is junk. It isn't. But when a customer asks us to install new siding on their home, we only put up James Hardie. That's a deliberate standard, not a marketing line, and we think homeowners deserve the real reasoning behind it.
Where the Two Products Actually Differ
The gap between fiber cement brands isn't in the raw chemistry — it's in the manufacturing consistency, the finish system, and how well the product is engineered for a specific climate. Skagit County isn't a mild, dry place. We get driving rain off the water, salt-laden air working its way inland from the Sound, and a moss and algae season that runs longer here than it does on the east side of the state. Siding on a Mount Vernon home earns its keep every single month of the year.
Factory Finish
James Hardie's ColorPlus finish is baked on in a controlled factory environment through multiple coats, and it comes with its own dedicated finish warranty separate from the base product warranty. That matters because a factory-cured finish resists fading and chipping in a way that's hard to match with a finish applied under less tightly controlled conditions. When we're not confident a finish will hold its color and seal through a decade of Pacific Northwest weather, we don't want our name on the install.
Climate-Engineered Product Lines
Hardie builds region-specific formulations — including HZ5 lines engineered for wetter, harsher climates like ours — with moisture and freeze-thaw behavior tuned for exactly the conditions Skagit County throws at a house. That's a level of climate-specific engineering we haven't seen matched elsewhere, and for a product that's going to sit on a wall absorbing rain off the water for the next 30 years, that engineering isn't a nice-to-have.
Warranty Structure
Hardie's warranty is transferable to a new owner if the home sells, which matters a lot in a market where houses change hands. It's also backed by a large, well-established manufacturer with a long track record of honoring claims. A warranty is only as good as the company standing behind it years down the road, and that track record is part of what we're vouching for when we install it.
Installation Consistency Matters More Than People Think
Fiber cement is not a forgiving product to install poorly. Nail placement, gapping, caulking, and flashing details all affect how the board handles moisture over time — and moisture is the one thing Mount Vernon has no shortage of. Our crews install one system, day in and day out. That focus means fewer surprises: the same fastening schedule, the same trim details, the same moisture-management approach on every job. Splitting our install standards across multiple manufacturers' spec sheets would mean more room for the kind of small mistakes that don't show up until year five or six, usually right around a window flashing or a butt joint.
Why We Standardized on James Hardie
| Factor | What It Means Locally |
|---|---|
| Factory-cured finish | Better fade and chip resistance through wet Skagit County winters |
| Climate-specific HZ lines | Engineered for high-moisture, coastal-influenced conditions |
| Transferable warranty | Protects home value and resale in a market where houses turn over |
| Single-system install standard | Fewer installation-sensitivity errors across our crews |
None of this means Allura is a bad product on someone else's house. It means that when we weigh finish durability, climate-specific engineering, warranty backing, and installation consistency together, James Hardie is the product we're willing to put our own standard behind on every siding job we take on in Mount Vernon and across Skagit County.
