Anacortes Siding Vinyl Siding Isn't a Bad Product — It's Just Not the Right One for Here
We get asked about vinyl siding often enough that we want to lay out our thinking plainly. Vinyl has real advantages: it's inexpensive up front, it never needs painting, and in a mild, dry climate it can perform reasonably well for years with almost no upkeep. If we operated somewhere with less rain, less wind off the water, and less shade, we might feel differently. But we work on homes in Anacortes and across Skagit County, and the conditions here are specific enough that we've made a standing decision not to install it.
What Anacortes' Climate Actually Does to Vinyl
Anacortes sits right on the water, and that matters more for siding than most homeowners realize. Salt-laden air off Rosario Strait and Padilla Bay settles on exterior surfaces year-round, and vinyl's factory color layer is thin — it fades and chalks faster under salt exposure than it does inland. Once that color starts to go, there's no repainting your way back to a clean look without replacing panels, because vinyl paint adhesion is unreliable and most manufacturers won't warranty a painted panel.
Then there's the rain. Skagit County doesn't just get a lot of precipitation, it gets a lot of wind-driven rain, especially during fall and winter storms coming off the Strait. Vinyl siding is installed as an overlapping shingle system that relies on gravity to shed water — it is not sealed at the seams by design. In a straight-down rain that works fine. In sideways, wind-pushed rain, water can work its way behind panels at laps, corners, and penetrations. The siding itself won't rot, but the wood sheathing, house wrap, and framing behind it can, and by the time a leak shows up on the inside, there's often been damage building for a while.
The third factor is moss. Anacortes' tree cover, humidity, and long shoulder seasons of damp, shaded weather make this excellent moss-growing territory. Moss and algae growth on vinyl siding is mostly cosmetic, but it collects in the panel's overlapping joints and butt seams — the same places water is already trying to get behind the siding — and it's genuinely difficult to clean out of those grooves without a pressure washer forcing water into those same gaps. It becomes a maintenance chore that works against the very reason a lot of people choose vinyl in the first place.
The Short Version
- Salt air: fades vinyl's color faster than inland climates, with no good repair option short of replacement
- Driving rain: vinyl sheds water by design rather than sealing against it, which matters more in wind-driven storms
- Moss season: growth collects in lap seams, the same vulnerable points water is trying to get behind
Installation Sensitivity Is a Real Factor
Vinyl siding also has to be installed loose in its nailing slots so it can expand and contract with temperature swings. Nail it too tight and panels buckle or "oil-can" — that rippled, wavy look you sometimes see on older installations. Nail it too loose and wind can catch panels in a gust, especially in more exposed coastal spots. Getting it right requires real attention to detail, and the margin for error is narrow. We'd rather not install a product where a rushed or inexperienced crew can produce a visibly flawed result that isn't obvious until the first hot afternoon or windstorm after installation.
The Warranty Reality
Most vinyl warranties are prorated, meaning the coverage value declines every year you own the product — read the fine print and the "lifetime" language usually applies to the original owner only, with fading and impact damage carved out or capped early. That's standard across the vinyl industry, not a knock on any one brand, but it's worth knowing before you choose a siding product you expect to keep for decades.
Why We Install James Hardie Instead
We standardized on James Hardie fiber cement for the properties we work on, largely because it addresses the specific problems above. It's non-combustible, which matters given the Pacific Northwest's increasing wildfire smoke and ember exposure seasons. Hardie's ColorPlus factory finish is baked on rather than sprayed on, and it's engineered to hold color longer under UV and salt exposure than vinyl's coating. Hardie also makes climate-specific HZ product lines, and the HZ5 version is engineered for wet, humid, freeze-prone regions like ours — it resists moisture-related damage better than a one-size-fits-all product. It carries a strong, transferable non-prorated warranty, which matters if you ever sell the house. None of that makes it maintenance-free — it still needs to be caulked and repainted eventually — but the maintenance it does need is straightforward and doesn't creep up on you the way trapped moisture behind vinyl can.
