Anacortes Board & Batten Siding on Guemes Island
Guemes Island sits just across the channel from Anacortes, but it lives by its own rules. It's ferry-access only, wrapped in Salish Sea salt air, and shaded by enough fir and cedar canopy that entire sides of a house can stay damp for weeks at a stretch. Board and batten siding is one of the most requested looks out here — it fits the cabin-and-shoreline character of the island — but it's also a style that punishes a sloppy install faster than standard lap siding does. Get the substrate, flashing, and material wrong, and you're looking at streaking, soft spots, and battens popping loose well before their time. Get it right, and it's one of the most durable, good-looking exteriors you can put on a Guemes Island home.
This page covers what board and batten actually needs to hold up out here, what a correct installation looks like, and why we only do this work in James Hardie fiber cement — never vinyl, LP SmartSide, or engineered wood panels — on this island or anywhere else in Skagit County.
Why Board & Batten Fits This Island
The Look Homeowners Are After
Board and batten reads as clean, vertical, and a little more rustic-modern than horizontal lap. It pairs well with the mix of older cabins, newer builds, and shoreline homes you'll find scattered across Guemes Island, and it photographs well against the evergreen tree line most properties sit inside. That's the aesthetic case for it, and it's a legitimate one.
A Style With Real Job-Site Demands
What a lot of homeowners don't realize is that board and batten isn't just lap siding turned sideways. The wide flat panels and narrow battens create a different water-management problem: instead of overlapping courses that naturally shed rain, you've got vertical seams covered by battens, wider open faces catching wind-driven rain dead-on, and — depending on the substrate — a lot more surface area exposed to standing moisture if the drainage plane behind it isn't done correctly. On a protected inland lot that forgiveness gap might not matter for years. On an island lot facing open water or sitting under heavy shade, it shows up fast.
What Guemes Island's Climate Actually Does to Siding
Salt Air and Corrosion
Being surrounded by the Salish Sea means airborne salt is a constant, low-grade factor here in a way it isn't for homes further inland in Skagit County. Salt air accelerates corrosion on anything metal — fasteners, flashing, hardware — and it doesn't take a waterfront lot to feel it; the whole island gets some exposure. Siding systems that rely on standard fasteners or bare-metal trim tend to show rust streaks and loosening joints years before they should.
Driving Rain and Wind Exposure
Islands don't get the wind-buffering that a house tucked into a mainland neighborhood gets. Storms coming off the water hit Guemes Island with more direct force, and that means rain doesn't just fall on siding here — it drives into it horizontally, especially on the west- and south-facing walls that catch the prevailing weather. Board and batten's wide flat panels are more exposed to that pressure than narrower lap boards, which is exactly why the flashing and drainage details behind the panels matter so much more here than they would on a calm, sheltered elevation.
The Long Moss Season
Guemes Island's tree cover keeps a lot of homes in partial shade most of the year, and combined with Pacific Northwest rainfall, that means moss and algae growth on north-facing and shaded walls almost year-round rather than just a winter season. Any siding material that holds surface moisture — or that has to be repainted regularly to keep looking clean — is going to fight a losing battle against that kind of exposure. Siding here needs a factory finish and a moisture-resistant core that don't depend on the homeowner staying on top of maintenance to look decent.
What a Correct Board & Batten Installation Involves
Drainage Plane and Rainscreen
Because vertical siding sheds water differently than lap siding, a correct install starts behind the panel — with a weather-resistant barrier and, on most Guemes Island jobs, a rainscreen gap that lets any moisture that gets past the cladding drain and dry out instead of sitting against the sheathing. Skipping this step is the single most common shortcut we see on vertical siding jobs, and it's the one that causes the most damage down the line because it's invisible until something fails.
Flashing, Fasteners, and Batten Spacing
Every horizontal transition — window heads, roof-wall intersections, deck ledgers — needs flashing detailed to kick water out and away from the wall, not just caulked and hoped for. Given the salt air out here, we use corrosion-resistant fasteners rather than the standard-grade hardware that's fine for a mainland, inland project. Battens need consistent spacing over the panel seams they're covering, with enough fastening to handle wind load without over-driving nails through the fiber cement.
Comparing Installation Approaches
Not every board and batten job is built the same way, and the differences show up in how long it lasts, not in how it looks on installation day. Here's what tends to separate a correct job from a corner-cut one:
| Cost Factor | Effect on the Job |
|---|---|
| Rainscreen gap vs. direct-to-sheathing | Adds labor and material up front; substantially reduces trapped-moisture risk on exposed and shaded walls |
| Stainless or coated fasteners vs. standard | Modest cost increase; prevents the rust streaking and loosening common in salt-air environments |
| Factory-finished panels vs. field-painted | Higher material cost; removes the recurring repaint cycle moss and UV exposure otherwise force |
| Ferry-based material delivery and staging | Requires more upfront scheduling; avoids mid-job delays and repeat ferry trips that stall a crew |
| Detailed flashing at every penetration | Adds install time; the single biggest factor in whether wind-driven rain stays out |
Why We Install Only James Hardie Fiber Cement Here
We don't offer vinyl, LP SmartSide, or engineered wood board and batten, and that's a deliberate standard, not an oversight. Vinyl vertical panels can look the part but they expand and contract more with temperature swings, which shows at the battens over time, and they don't hold up to direct wind-driven rain and salt air the way a fiber cement panel does. Engineered wood products depend on their factory coating and careful edge-sealing to keep moisture out — once that coating is compromised at a cut edge or fastener hole, the substrate itself is vulnerable to swelling and rot, which is a real risk in a climate that stays wet as long as this one does.
James Hardie's fiber cement is non-combustible, dimensionally stable in wet-dry cycling, and comes with a factory-applied ColorPlus finish that's baked on rather than field-painted — which matters directly for the moss-season repainting problem described above. Hardie also engineers its formulations by climate zone; the version specified for the Pacific Northwest (HZ5) is built for our wet, moderate-freeze conditions rather than a one-size-fits-all mix. For board and batten specifically, we install Hardie's vertical panel and batten systems, backed by a transferable limited warranty — a warranty structure a homeowner can actually count on if the property changes hands, which is common with island properties.
Our Process for a Guemes Island Job
Planning Around the Ferry
Every Guemes Island project starts with logistics most mainland jobs don't have to think about. We plan material orders and cut lists in advance so a full ferry load of siding, trim, and fasteners arrives ready to install — not so we're making repeat trips mid-project chasing a missed piece. That planning is part of why an island-experienced crew gets these jobs done on schedule.
Assessment and Detailing
Before we quote the job, we walk the exposures — which walls take direct weather, which stay shaded and moss-prone, where the existing flashing and trim are already showing wear. That assessment drives where we add rainscreen detailing, upgrade fastener spec, or pay extra attention to flashing, rather than applying the same generic approach to every wall of the house.
What to Ask Before You Hire
Board and batten hides a lot of its quality behind the finished surface. Before hiring anyone for this work on Guemes Island, it's worth asking:
- Will you install a rainscreen or drainage gap behind vertical panels, or fasten directly to the sheathing?
- What fastener grade are you using, given the salt air out here?
- How do you flash window heads, roof-wall intersections, and batten seams?
- Is the siding factory-finished, or will it need field painting and future repainting?
- Have you worked on Guemes Island before, and how do you handle material delivery via ferry?
- What warranty applies to both the material and the labor, and is it transferable if the home sells?
Why Local Experience on This Island Matters
A crew that hasn't worked Guemes Island before is learning on your project — figuring out ferry timing, discovering which walls get hit hardest by salt spray and wind-driven rain, realizing too late that a shaded north face needed a different moisture strategy than the sun-facing side. A crew that already works out here has already made those adjustments on other island homes. That experience shows up in fewer surprises, fewer delays, and a finished job that's actually built for Guemes Island's conditions rather than for a generic Skagit County lot.
