Ferndale Vinyl siding shows up on a lot of homes around Ferndale, and it's easy to see the appeal. It's inexpensive, it's fast to install, and it doesn't need painting. If a homeowner asks us to bid a vinyl job, we're going to be straight with them: we don't install it. Not because it's a scam or a bad product by definition, but because after years of working on homes along the Whatcom County coastline, we've seen where it holds up and where it doesn't — and we'd rather put our name on something built for this specific climate.
What vinyl siding actually gets right
To be fair to the product, vinyl siding earns its popularity honestly. It's one of the most affordable exterior claddings on the market, it never needs repainting, and it resists rot outright because it isn't wood-based. For a mild, dry climate, or for an owner planning to sell in a few years, it can be a perfectly reasonable choice. We're not here to tell homeowners it's junk — we're here to explain why it's not what we choose to put on homes in this part of Washington.
Where the Whatcom County climate exposes it
Ferndale sits close enough to Bellingham Bay and the Salish Sea that salt-laden air is a constant, low-grade presence on every exterior surface. Add in the region's long stretch of driving rain from fall through spring, plus a moss and algae season that can run most of the year in shaded, north-facing spots, and you've got a climate that tests the weak points of any siding product hard.
Vinyl's specific weak points line up uncomfortably well with those conditions:
- Thermal movement. Vinyl expands and contracts significantly with temperature swings. Panels are engineered to float in their tracks rather than fasten rigidly, which means installation tolerances matter enormously. Nail it too tight and panels can buckle or warp; nail it too loose and wind-driven rain works its way behind the panels.
- Wind and driving rain. Whatcom County storms regularly bring sideways rain off the water. Vinyl relies on lapped panels and a drainage plane behind it to manage that moisture — if the water-resistive barrier or flashing details aren't close to perfect, water finds its way behind the cladding, where it can sit against sheathing for months without being visible from outside.
- Moss and algae staining. Vinyl's textured, low-gloss surface and the seams between panels give moss and algae plenty of places to establish, especially on shaded elevations. Cleaning it without damaging the surface or driving water behind the panels takes real care.
- UV and cold brittleness. Over years of sun exposure, vinyl can fade unevenly and become more brittle in cold weather, making it more prone to cracking from stray impacts — a baseball, a ladder, a wind-thrown branch.
- Repair and matching. Vinyl color fades over time, so a panel replaced five or ten years after installation rarely matches the surrounding siding exactly, leaving a visible patch.
None of this means every vinyl installation fails. It means vinyl has a narrower margin for error in a climate like ours, and the consequences of a missed detail — trapped moisture behind an exterior wall — are exactly the kind of problem that stays hidden until it's expensive.
Why we standardized on James Hardie fiber cement instead
We made a decision as a company to install James Hardie fiber cement siding exclusively, and it comes down to matching the material to the environment we actually work in. Fiber cement is dimensionally stable — it doesn't expand and contract the way vinyl does, so it holds tighter tolerances at seams and trim over decades, not just years. It's non-combustible, which matters increasingly to insurers and homeowners alike. And it's engineered, not just painted: Hardie's ColorPlus finish is baked on at the factory in a controlled process, giving it better fade and moisture resistance than field-applied paint, backed by a real transferable finish warranty.
Hardie also builds climate-specific product lines — including HZ5 formulations engineered for wetter, harsher regions like ours — which means the siding itself is designed around the moisture and temperature cycling that Pacific Northwest coastal weather puts it through, rather than a one-size-fits-all approach.
That doesn't mean fiber cement is maintenance-free or immune to moss. Nothing on a home's exterior is. But it gives us a material with a wider margin for error, a manufacturer warranty structure we trust, and a track record on homes up and down this coastline that we can stand behind when we tell a homeowner it'll still look right in twenty years.
The honest bottom line
Vinyl siding isn't a bad product — it's a product built for a different set of trade-offs than the ones we prioritize. Given Ferndale's salt air, driving rain, and moss season, we'd rather install something engineered with more margin for this specific climate, even if it costs more upfront. That's a professional standard we hold to on every job, not a sales pitch.
