Anacortes Siding Ship Harbor sits on the west side of Fidalgo Island, close to the water and the ferry terminal, which means homes here take weather straight off the Salish Sea with very little to break it up first. Board and batten has become a popular choice in this part of Anacortes — the vertical lines suit both the newer builds going up near the shoreline and the older cottages further back from it — but board and batten is also one of the least forgiving siding profiles when the climate doing the testing is this wet and this salty. Every seam between a board and the batten covering it is a place water can try to get behind the wall, and Ship Harbor gives that water a lot of help getting there.
We install James Hardie fiber cement board and batten exclusively for homes in this area, and we build every joint, fastener pattern, and flashing detail around what direct marine exposure does to a wall over decades, not around what looks tight on the day the crew packs up.
What Ship Harbor's Exposure Does to a Board & Batten Wall
Wind-Driven Rain Straight Off the Water
Rain rarely falls straight down this close to the shoreline — wind pushes it sideways into the wall, and a vertical siding profile with battens running the full height of the house gives that rain a lot of joint length to test. A batten that's caulked tight instead of properly lapped, or face-nailed with no room for the wood-fiber core to move, ends up pulling moisture toward the fastener line instead of shedding it back off the wall.
Salt Air and Fastener Corrosion
Board and batten uses more fasteners per square foot than standard lap siding, since both the boards and the battens covering their seams need to be secured. That makes fastener spec — corrosion resistance, size, spacing — carry more weight on this profile than most, and it matters more here than it would a few miles inland, simply because Ship Harbor sits right in the path of steady salt-laden air.
A Long Moss Season on Shaded Sides
Anacortes' damp season runs long, and any wall that stays shaded or tucked under tree cover holds moisture longer than one that gets regular sun. A batten set tight against its board with no clearance to breathe traps that dampness right at the seam — which is exactly where moss, mildew staining, and eventual softening of whatever's underneath tend to start.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already carries, because it has more seams and more exposed edge than most other profiles. That's part of why we don't offer LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten for Ship Harbor homes. Those are legitimate products, and other contractors install them competently — we made a professional call that on a profile this seam-heavy, in a location with this much direct water and salt exposure, we'd rather stand fully behind one system than split our attention across several.
| Material | Behavior at Batten Seams | Upkeep in Marine Exposure | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup along the joint | Low; factory finish resists moss and salt fading | 30+ years installed to spec |
| LP SmartSide (engineered wood) | More sensitive to moisture at cut edges and fastener holes | Moderate; edge sealing needs regular attention | 15-25 years, climate-dependent |
| Vinyl | Can gap or warp at battens under sun and cold cycling | Low, but hidden moisture problems are hard to catch | 20-30 years, variable |
| Cedar | Absorbs water readily at every seam without regular sealing | High; repainting or resealing on a recurring cycle | 15-25 years with consistent upkeep |
Fiber cement's stability at the seam is the property that matters most on a profile made entirely of vertical joints. Hardie's factory-applied ColorPlus finish also means the cut edges we prime on site are the exception, not the rule — unlike a field-painted material, where the whole wall's finish depends on paint holding up against salt air and UV year after year.
What a Correct Board & Batten Install Actually Involves
The finished look is simple — vertical boards, battens over the seams — but a correct install on a Ship Harbor lot has more happening behind that surface than it does on a sheltered inland home:
- Weather-resistive barrier installed and lapped correctly before any siding goes on the wall
- A drainage gap or rainscreen behind the siding so moisture that gets past the surface can dry out instead of sitting against the sheathing
- Corrosion-resistant fasteners at the manufacturer's specified spacing, sized for coastal exposure rather than a generic inland spec
- Battens set with proper clearance rather than caulked tight, so the wall can shed water instead of holding it at the seam
- Correctly flashed and lapped transitions at windows, doors, corners, and the base of the wall, where the vertical run meets a horizontal surface
- Factory-cured ColorPlus finish protected by cutting boards face-down and priming any field-cut edges before they go up
Skip any one of these and the wall can still look right for a season or two. The problems that follow — staining along the seams, softening near the base, paint failure at the battens — take a few wet winters to show up, which is exactly why a shortcut install can pass a quick look before the homeowner ends up dealing with the consequences.
Our Process for a Ship Harbor Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved — which ones take direct wind and rain off the water, which sides stay shaded and slow to dry, and whether the existing wall assembly already has moisture damage that needs addressing before new siding goes up. Board and batten over a wall with hidden rot just buries the same problem under new material.
Planning Before Install Day
We work out batten spacing, corner details, and how the siding will meet windows, trim, and rooflines before any material gets cut. On a profile with this many seams, sorting out the details on paper first keeps the crew from improvising in the field, which is usually where corners get cut.
Installation to Manufacturer Spec
Every fastener, gap, and flashing lap follows James Hardie's published installation requirements for this climate zone, not a generic national minimum. That's what keeps the manufacturer's warranty valid, and it's the reason the wall is built to perform for decades instead of just looking finished on day one.
Final Walkthrough
We walk the completed job with you, cover what little maintenance board and batten actually needs, and make sure you know what a healthy seam and a problem seam look like if you ever want to check the wall yourself down the road.
Why Hire a Crew That Already Works Ship Harbor
Board and batten rewards local experience in a way a lot of siding profiles don't, because its failure points are subtle and slow to surface. A crew that's already installed this profile on homes throughout Ship Harbor and the rest of Anacortes has seen which wall orientations need extra attention because of direct water exposure, how much batten clearance actually holds up in a climate this consistently wet versus what a generic install guide assumes, and where a rainscreen gap is doing real work rather than being an optional extra. That judgment doesn't show up on a spec sheet — it's the difference between a wall that still looks and performs the same in fifteen years and one that's showing seam staining by year five.
Cost Factors for Board & Batten in This Area
Board and batten typically runs more per square foot than standard lap siding, mostly because of the added batten material and the extra labor of fastening and detailing two layers instead of one. Beyond the base material, a few things move the price on a given Ship Harbor home:
| Factor | Why It Matters |
|---|---|
| Wall height and complexity | More corners, gables, and transitions mean more cuts and flashing details |
| Existing wall condition | Moisture damage found during tear-off needs repair before new siding goes up |
| Batten spacing and reveal | Tighter spacing uses more material and more fastening labor |
| Exposure level of the lot | Homes with direct, unbroken water exposure warrant tighter fastener spacing and flashing detail |
| Access and site conditions | Narrow lots or limited staging room near the water can add labor time |
We'll walk your specific property and give you real numbers rather than a rough square-footage guess — two Ship Harbor homes with similar footprints can land at very different costs depending on how exposed they are and what shape the existing wall is in.
Getting It Right the First Time
Board and batten is not a forgiving profile to fix after the fact. Because the battens sit over the seams between boards, correcting a bad install usually means pulling battens, boards, or both, rather than a quick patch. That's why we treat the planning and detailing phase of a Ship Harbor project as seriously as the installation itself — the cost of doing it right the first time is a lot less than the cost of tearing out a wall that was rushed.
