Ferndale Siding One Product, No Exceptions
Homeowners sometimes ask why we don't offer a menu of siding brands the way some contractors do. The honest answer is that we looked at what actually survives on homes in Ferndale and the rest of Whatcom County — year after year, through wet winters, salt-laden air off the Strait, and the long stretch of gray months when moss and algae get a foothold on anything that holds moisture — and James Hardie fiber cement was the clear, repeatable winner. So that's what we install. Not because we get something out of picking one brand, but because we got tired of watching other products struggle here and didn't want our name on that outcome.
What Fiber Cement Actually Is
James Hardie siding is made from cement, sand, and cellulose fiber, cured into planks and panels that are dimensionally stable and non-combustible. It doesn't absorb water the way wood-based products do, it doesn't expand and contract with humidity swings the way vinyl does, and it holds paint and factory finishes far longer than primed wood siding. In a region where rain is a near-constant presence for months at a time, that moisture behavior is the whole ballgame. Siding that swells, warps, or lets water track behind it eventually causes problems that go well beyond the surface — rot, mold, and sheathing damage that cost far more to fix than the siding itself.
Built for This Specific Climate — Not Just "the Northwest"
James Hardie engineers its products by climate zone, and homes here fall into the HZ10 category, engineered for regions with sustained moisture exposure. That's not marketing language — it affects the actual formulation and moisture-management performance of the board. A siding product engineered for a dry inland climate and shipped everywhere doesn't hold up the same way on a home a few miles from Bellingham Bay dealing with driving rain and salt air. Choosing HZ10 product for a Ferndale home isn't an upsell; it's matching the material to the job.
ColorPlus Factory Finish
A lot of siding failure isn't the substrate — it's the paint. Field-applied paint jobs, even good ones, are at the mercy of weather during application and tend to need recoating within several years, especially on a home exposed to constant damp and UV cycling. Hardie's ColorPlus finish is baked on in a controlled factory environment, cures harder than field-applied paint, and resists fading, chipping, and moisture intrusion at the finish layer far longer. It also comes with a dedicated finish warranty separate from the substrate warranty — two layers of coverage instead of one.
The Warranty Actually Means Something
James Hardie backs its siding with a transferable, non-prorated limited warranty on the substrate, and a separate warranty on the ColorPlus finish. Transferable matters if you ever sell the house — it's a selling point buyers' inspectors recognize. Non-prorated matters because some warranty structures shrink in value every year until they're nearly worthless by the time you'd actually need them. We only want to install products with warranty language that holds up when it's actually needed, not just on the sales sheet.
Installation Is Half the Product
Fiber cement only performs as designed when it's installed to Hardie's published specifications — correct clearances off grade and roof lines, proper flashing and house-wrap integration, correct fastener placement, and factory-cut or properly sealed field cuts. Sloppy installation is a leading cause of siding complaints across every brand, and Hardie is no exception. That's part of why we don't split our attention across multiple product lines — our crews install one system, know its details cold, and don't have to relearn flashing details or fastener schedules from one job to the next.
How the Options Compare
| Factor | James Hardie Fiber Cement | Vinyl / Engineered Wood |
|---|---|---|
| Moisture behavior | Non-combustible, dimensionally stable | Prone to warping, swelling, or heat distortion |
| Finish durability | Factory-baked ColorPlus finish | Field paint or molded color, fades faster |
| Warranty structure | Transferable, non-prorated | Often prorated or limited in transferability |
| Climate matching | HZ10 formulation for wet, coastal zones | Generally one-size-fits-all nationally |
Why This Matters More in Whatcom County
Ferndale sits close enough to the water that salt air is a real factor on window frames, fasteners, and siding finishes. Combine that with the region's moss season — those months where north-facing walls and shaded elevations stay damp for weeks at a stretch — and you've got conditions that expose weaknesses in lesser siding systems fairly quickly. We'd rather install one product we trust completely than offer a lineup and let homeowners find out the hard way which ones don't hold up here.
