Anacortes Siding Vinyl Siding Isn't a Bad Product — It's Just Not What We Install
We get asked about vinyl siding almost every week, usually from homeowners comparing bids and wondering why our estimate doesn't include it. The honest answer is that we made a deliberate decision years ago to install James Hardie fiber cement siding exclusively, and vinyl didn't make the cut. That's not because vinyl is junk. It's inexpensive, it's widely available, it never needs painting, and for a lot of the country it does a perfectly adequate job. Our issue isn't with vinyl in general — it's with how vinyl performs specifically on homes exposed to Anacortes weather, and what we're willing to put our name behind.
This page walks through what vinyl does well, where it struggles in our climate, and why we'd rather turn down a job than install a product we don't think holds up here.
What Vinyl Siding Gets Right
Credit where it's due. Vinyl has a real place in the siding market, and understanding its strengths is part of understanding why the trade-offs matter.
- Lower upfront material cost compared to fiber cement, wood, or engineered wood siding.
- No repainting — color runs through the panel rather than sitting on top of it as a coating.
- Fast installation on straightforward, single-story homes with simple wall lines.
- Reasonably impact-resistant in moderate temperatures, and it won't rot the way untreated wood can.
For a lot of markets, those strengths outweigh the downsides. Anacortes and the rest of Skagit County are a different environment, and that's where the calculation changes.
Why Our Local Climate Changes the Calculation
Anacortes sits on Fidalgo Island, surrounded by saltwater on three sides, with a marine climate that brings salt-laden air, driving rain off the water, and a moss and algae season that can stretch from fall through spring. None of that is a problem a siding material has to solve in isolation — it's the combination that's hard on lower-grade materials, and vinyl in particular has a few specific weak points that show up faster here than they would in a drier, more inland climate.
Three things matter most for siding performance in our area: how a product handles sustained moisture and wind-driven rain, how it holds up to salt exposure over decades, and how easy it is to keep clean when moss and algae are trying to grow on every north-facing wall for half the year.
How Vinyl Siding Actually Manages Water
This is the part most homeowners aren't told when they're comparing bids: vinyl siding is not a waterproof cladding. It's designed as a rain screen — it sheds the bulk of the water and lets the rest drain and evaporate behind the panel, relying entirely on the weather-resistant barrier (the house wrap) and flashing details underneath to do the actual waterproofing. Vinyl panels are also installed with a deliberate gap for expansion, and that gap, combined with the panel's loose-hang design, means wind-driven rain can and does get behind the siding under the wrong conditions.
In a climate with occasional showers, that's a minor design footnote. In a climate with sustained, wind-driven rain coming off the water — which is a normal winter pattern here, not an occasional storm — the quality of the barrier behind the vinyl becomes the entire ballgame. If the house wrap, flashing, and drainage gap aren't done exactly right, water sits behind the panels longer than it should, and it's doing that against sheathing that's already dealing with our long wet season. Vinyl itself won't rot, but the wall assembly behind it can, and vinyl's loose-fit design gives you less margin for error than most homeowners assume.
Thermal Movement and Buckling
Vinyl expands and contracts significantly with temperature swings — more than most siding materials. It's designed to move within its nailing slots, which is why installers are trained to "hang" it rather than nail it tight. Nail it too snug, and panels buckle, ripple, or pop off track during a hard freeze or a hot stretch. It's one of the more common installation defects we see on vinyl jobs done by crews who aren't specifically trained on it, and it's a defect that's largely invisible until the temperature does something unusual.
Wind Exposure on Fidalgo Island
Wind load matters more here than in a lot of inland markets. Homes on Fidalgo Island and along the water in Anacortes catch gusts that interior Skagit County properties don't see nearly as often. Vinyl siding is rated for wind resistance, but that rating depends heavily on panel gauge (thickness), fastening pattern, and how tightly the installer follows the manufacturer's nailing schedule. Thinner, budget-grade vinyl — which is what a lot of competitive bids are built around — has a noticeably lower wind rating than the thicker profiles, and it's not always obvious from a sample chip which grade you're actually getting quoted.
Salt Air, UV, and the Long-Term Look of Vinyl
Vinyl's color is mixed into the material rather than painted on, which sounds like a durability win, and to some degree it is. But vinyl still chalks and fades under sustained UV exposure, and salt air accelerates that process along with general surface degradation. Darker vinyl colors are especially prone to heat absorption and warping, which is part of why manufacturers restrict how dark a color you can order in vinyl — a limitation you don't run into with factory-finished fiber cement.
Fasteners are the other quiet issue. Vinyl siding is typically hung with standard galvanized nails or staples. In a salt-air environment, lower-grade fasteners corrode faster than they would a few miles inland, and once a fastener starts to fail, the panel above it loses its hold. It's a slow problem, not a dramatic one — which is exactly why it tends to go unnoticed until a section of siding is visibly loose.
Moss, Algae, and a Long Wet Season
Skagit County's moss season is long, and vinyl siding — especially on shaded, north-facing walls — is not immune to algae and moss growth. Cleaning it requires care: pressure washing vinyl at the wrong angle or pressure can force water behind the panels or crack aged, UV-brittle material, particularly on older installations. Homeowners end up choosing between letting the growth sit (which holds moisture against the wall longer) or cleaning it in a way that carries some risk to the siding itself. It's a maintenance trade-off that's more pronounced here than in drier parts of the state.
Installation Sensitivity: What Separates a Good Vinyl Job From a Bad One
A lot of vinyl's real-world problems trace back to installation, not the material itself. That's true of most siding, but vinyl has a narrower margin for error because so much of its performance depends on details that aren't visible once the job is done — nailing tension, drainage gap, flashing laps, and how it's fastened around penetrations. If you're getting bids that include vinyl, these are the things worth asking about before you sign anything:
- What gauge (thickness) of vinyl is actually being quoted, and what's its wind rating?
- Is the crew nailing to manufacturer spec — hung loose in the slot, not nailed tight?
- What house wrap and flashing details are going in behind the panels, and by whom?
- How is the drainage gap at the bottom of the wall and around windows being handled?
- What's the manufacturer's actual wind and impact warranty, and is it prorated?
- Who's responsible if water damage shows up behind the siding five years from now — the installer or the manufacturer?
Vinyl vs. James Hardie Fiber Cement: A Side-by-Side Look

| Color/finish | Color mixed through material; fades and chalks with UV and salt air over time | ColorPlus factory-baked finish; formulated for UV and color retention |
| Moisture handling | Not waterproof; relies entirely on barrier and drainage gap behind it | Engineered HZ product line for wet/coastal climates; still requires correct install |
| Maintenance | Periodic cleaning; risk of cracking with aggressive pressure washing | Periodic cleaning; more tolerant of pressure washing when cured |
| Warranty | Often prorated; limited transferability | Long-term, non-prorated product warranty with transfer provisions |
| Upfront cost | Lower | Higher |
Why We Standardized on James Hardie
We install James Hardie fiber cement siding exclusively — not LP SmartSide, not other fiber cement brands like Cemplank or Allura, not primed spruce or cedar, and not vinyl. It's a narrower lineup than most contractors offer, and that's the point. It means every crew on our team knows one system inside and out, we're not guessing at installation specs across five different materials, and every home we finish is backed by the same warranty structure and the same product engineering.
James Hardie is non-combustible, holds its factory-applied ColorPlus finish far longer than a painted or through-colored alternative, and its HZ5 product line is specifically engineered for climates like ours — freeze-thaw cycling, sustained moisture, and salt exposure included. It's not immune to bad installation any more than vinyl is, but the material itself gives a wall assembly more margin when the Anacortes weather does what it does most winters: driving rain, wind off the water, and months of damp, mossy conditions in between.
None of this means vinyl siding is a scam or that everyone who's installed it made a mistake. It means that after years of doing exterior work in this specific climate, we decided we'd rather install one product well than several products with varying degrees of confidence — and fiber cement is the one we trust on our own bids.
