Ferndale Siding Vinyl Siding: What It Gets Right
We should say this up front: vinyl siding isn't a bad product. It's inexpensive, it goes up fast, and for a lot of homes in a lot of climates it does an adequate job for a while. If price is the only factor on the table, vinyl will always look competitive on paper. We're not here to tell you vinyl is a scam or that every vinyl-clad home in Ferndale is falling apart. It isn't.
What we are here to explain is why, as a company that puts our name behind every install, we stopped offering it. That decision came down to how vinyl actually behaves over 15-20 years in this specific corner of Whatcom County — not how it performs in a showroom or in a climate that's nothing like ours.
How Vinyl Behaves Over Time
Vinyl is a thin plastic product, and plastic moves with temperature. It expands in the sun and contracts in the cold, which is why every vinyl installation manual calls for "loose-hung" nailing — the panels have to be able to slide slightly in their nail slots or they'll buckle. Get that detail wrong, or let a panel get pinned down over the years by paint, caulk, or a poorly placed fastener, and you get visible waviness that no amount of pressure washing fixes.
It's also a hollow, layered system. Every seam, corner post, and J-channel is a place where wind-driven rain can get behind the panel instead of running off the face of it. Vinyl itself doesn't rot, but the OSB sheathing and framing behind it can, quietly, for years, before anyone notices a soft spot near a window.
And because it's a petroleum-based plastic, vinyl is combustible. It melts and can contribute fuel in a fire rather than resisting it — a real consideration for any homeowner comparing exterior cladding, not a marketing talking point.
Why That Matters More in Ferndale
Whatcom County's climate is exactly the kind of environment that exposes vinyl's weak points faster than average:
- Salt air: Ferndale sits close enough to Bellingham Bay and the Salish Sea that salt-laden air is a constant. It accelerates corrosion of the fasteners and metal trim that vinyl systems depend on, and it works into every seam and J-channel over time.
- Driving rain: Our storms don't just fall straight down — wind-driven rain off the water pushes water sideways into laps and seams, which is precisely where a lapped, hollow-back system like vinyl is most vulnerable.
- A long moss season: Our extended damp, shaded stretches of the year are ideal for moss and algae growth. Vinyl's textured surface and narrow channels give moss plenty of places to take hold, and cleaning it off without damaging or discoloring the panel is a genuinely difficult, recurring job.
None of these conditions are unique to Ferndale, but together they're tougher on a thin plastic siding system than the drier, milder climates vinyl was originally popularized in.
The Trade-Offs, Side by Side
| Factor | Vinyl Siding | James Hardie Fiber Cement |
|---|---|---|
| Upfront cost | Lower | Higher |
| Combustibility | Combustible plastic | Non-combustible |
| Moisture path | Hollow lapped system, seam-dependent | Solid panel, engineered for regional moisture |
| Movement with heat/cold | Expands and contracts; can warp | Dimensionally stable |
| Factory finish | Color molded through, can fade/chalk | ColorPlus baked-on finish, resists fade |
| Typical warranty structure | Prorated after early years | Long-term, non-prorated options |
Why We Standardized on James Hardie
After years of doing tear-offs on homes with failing exterior cladding, we made a call: we only install James Hardie fiber cement siding. It's cement-based rather than plastic-based, so it doesn't expand and contract with every temperature swing the way vinyl does, and it's non-combustible. Hardie also builds its HZ5 product line specifically engineered for climates like ours — freeze-thaw cycles, sustained moisture, and coastal exposure — rather than a one-size-fits-all panel.
The ColorPlus factory finish is baked on rather than mixed through a plastic extrusion, which holds color and resists the chalking and fading that flat sun exposure and salt air can cause over time. And Hardie backs the product with a long, transferable warranty structure that reflects genuine confidence in how it holds up decades out, not just in year one.
We're not going to tell you vinyl is worthless — it has a place. But once we saw how differently these two products aged on real homes in real Whatcom County weather, we stopped installing one of them. That's not a sales pitch; it's just what convinced us.
