Anacortes Siding Vinyl Has Its Place — Just Not on the Homes We Build
Vinyl siding is the most common siding material sold in the country, and there's a reason for that: it's inexpensive, it goes up fast, and for a homeowner on a tight budget in a mild, dry climate, it can do an adequate job for a while. We're not going to pretend otherwise. But Anacortes isn't a mild, dry climate. Between the salt-laden air off Fidalgo Bay and the Guemes Channel, the driving rain that comes through Skagit County in the fall and winter, and a moss season that can stretch nearly half the year, vinyl gets tested here in ways it isn't in a lot of the country. After weighing those trade-offs, we made the decision to install only James Hardie fiber cement siding — and we think homeowners deserve to know why before they sign a contract for anything else.
Where Vinyl Struggles in Our Climate
Salt Air and Coastal Exposure
Anacortes sits close enough to saltwater that airborne salt is a real factor on a home's exterior. Vinyl itself doesn't corrode, but the exposed fasteners, trim, and hardware around it can, and the panels themselves become more brittle over time with sustained UV and salt exposure. Vinyl is manufactured with UV inhibitors, but they degrade on a timeline, and coastal exposure tends to accelerate that fading and brittleness compared to inland installations.
Driving Rain and Moisture Behind the Panels
Vinyl siding is installed as loose, overlapping panels that hang on a nailing hem rather than being fully fastened flat to the wall. That's by design — it lets the material expand and contract with temperature — but it also means the panels aren't a sealed surface. In a light, steady rain that's rarely an issue. In the kind of wind-driven, sideways rain that blows off the Sound during a fall or winter storm, water can work its way behind the panels at the laps and butt joints. Good installation with proper house wrap and flashing manages most of that, but it depends entirely on getting every detail right, and it puts a lot of faith in materials behind the wall that you can't see or inspect once the job is done.
A Long Moss Season
Skagit County's wet season gives moss and algae a long runway to take hold on north-facing walls and shaded sides of a house. Vinyl's slightly textured, low-gloss surface gives organic growth something to grip, and because vinyl can't be pressure-washed aggressively or scrubbed hard without risking cracking or dulling the finish, cleaning it without damaging it takes real care. Over a few moss seasons, siding that isn't cleaned gently and regularly can look tired well before its warranty runs out.
Installation Sensitivity and Temperature Swings
Vinyl has to be installed with expansion gaps at every nail and every joint, because it expands and contracts significantly more than fiber cement or wood with temperature changes. Nail it too tight and panels can buckle or oil-can in the sun; nail it too loose and panels can rattle or blow off in wind. Cold snaps also make vinyl more brittle and prone to cracking on impact — a stray branch, a ladder bump, a piece of hail. None of this makes vinyl a bad product on its own terms. It makes it a product where the margin for installation error is thin, and where the failures that do show up are often cosmetic and hard to fix without replacing whole sections, since discontinued colors and sun-faded panels rarely match a patch.
Why We Install James Hardie Instead
James Hardie fiber cement is a rigid, non-combustible material that holds its shape and its color in a way vinyl isn't built to. A few of the specific reasons it's a better match for this region:
- Dimensional stability — fiber cement doesn't expand and contract with temperature the way vinyl does, so seams and fasteners stay put through our seasonal swings.
- Factory-baked ColorPlus finish — a UV-cured finish that resists fading from salt air and sun exposure far better than the color-through pigment in vinyl, with a longer color warranty to back it.
- Engineered for this climate — Hardie's HZ5 product line is specifically formulated for the Pacific Northwest's moisture exposure.
- Non-combustible — fiber cement doesn't burn, melt, or warp from radiant heat the way vinyl can.
- A cleaner surface for moss and mildew management — the harder, smoother factory finish holds up to routine gentle washing without the cracking risk vinyl carries.
It costs more up front than vinyl, and we tell every homeowner that plainly. But when we're putting our name on an installation in a place with this much salt air, this much driving rain, and this long a moss season, we'd rather install something engineered for those conditions than something that just happens to be cheaper to buy.
