Bellingham Siding Why We Standardized on One Product
We get asked a lot why we don't offer a menu of siding brands. The honest answer: after years of tear-offs, warranty calls, and repair jobs across Bellingham and the rest of Whatcom County, we stopped installing anything but James Hardie fiber cement. Not because every other product is junk, but because Hardie is the one system that consistently holds up to what our climate does to a house — salt air rolling in off Bellingham Bay, driving rain for months at a stretch, and a moss season that never really ends. When your job is to protect a house for the next 30-plus years, you stop chasing options and start standardizing on what works.
What Fiber Cement Actually Is
James Hardie siding is made from sand, cement, and cellulose fiber, cured into a dense, stable board. It's non-combustible, doesn't swell or rot when it gets wet, and doesn't feed moss and mildew the way wood-based products can. That matters here more than in drier climates. Whatcom County homes spend a good chunk of the year damp, shaded, and slow to dry out, and siding that can't absorb and hold moisture has a real structural advantage over the decades, not just a cosmetic one.
The HZ5 Climate Engineering
James Hardie engineers several regional product formulations, and the HZ5 line is built for the wetter, cooler parts of the country, including the Pacific Northwest. It's formulated to resist moisture-related damage and hold paint adhesion in exactly the conditions Bellingham throws at a house year-round. This isn't a marketing label — it's a different manufacturing specification than the versions sold in dry southwestern markets, and it's the version we install.
ColorPlus Factory Finish
Most of what we install uses Hardie's ColorPlus finish — color baked on at the factory under controlled conditions, rather than field-painted after installation. A few reasons this matters for our area:
- Factory-cured finishes bond more consistently than paint applied on-site in variable weather, which is a real issue during Bellingham's wetter installation months.
- ColorPlus carries its own finish warranty separate from the substrate warranty, covering fading and peeling.
- Touch-up product is available for the rare nick or scratch, matched to the specific color.
We also install primed Hardie boards for homeowners who want a custom paint color, but for most projects we steer people toward ColorPlus because it removes an entire maintenance cycle from their future.
Product Lines We Install
| Line | Typical Use |
|---|---|
| HardiePlank lap siding | Most common choice, traditional lap look, several exposure widths |
| HardieShingle | Staggered or straight-edge shingle look without the maintenance of real cedar shingles |
| HardiePanel | Vertical board-and-batten and modern flat panel applications |
| HardieTrim | Fascia, corner boards, and window/door trim to match the field siding |
Installation Is Where Warranties Are Won or Lost
Fiber cement performs well, but only when it's installed to Hardie's published specifications — correct fastener placement, proper clearance from grade and roof lines, sealed joints, and rainscreen or drainage detailing appropriate to a wet climate. Get those details wrong and you can void the manufacturer warranty regardless of how good the product itself is. This is a big part of why we don't dabble in multiple siding brands: we've built our crews, our tooling, and our install checklist around one system, and we know it cold. A contractor splitting attention across five different products is more likely to miss a manufacturer-specific detail on any one of them.
The Warranty, Plainly
James Hardie backs its siding with a non-prorated limited transferable warranty, and ColorPlus finishes carry their own coverage terms. Warranty length and terms vary by product line and are spelled out in Hardie's published documentation — we'll walk you through the specifics for whatever product line fits your home rather than quote you a number that may not apply.
What This Costs Compared to Alternatives
Hardie fiber cement typically costs more upfront than vinyl and is generally in a comparable-to-somewhat-higher range than engineered wood siding, depending on product line and trim details. Where it tends to win is total cost of ownership: less repainting, less rot repair, less moss-related maintenance, and a longer service life before replacement. For a coastal Whatcom County home, that math usually favors Hardie once you look past year one.
Is Hardie Right for Every House?
Almost always, yes, for the reasons above — but we'll tell you plainly if there's a detail on your specific home (unusual framing, extreme exposure, a design element that doesn't suit fiber cement) worth discussing before we commit to a plan. Honesty on the front end saves everyone a headache later.
