Board & Batten Siding for Cap Sante Homes
Cap Sante sits up above the marina on the edge of Anacortes, and homes on that high ground get a version of the weather that flatter, more sheltered parts of town simply don't see as directly — open exposure to wind off the water, salt-carrying air, and rain that rarely falls straight down. Board and batten has become a popular siding profile on homes up there, partly because the vertical lines suit both the older character homes and the newer builds that share that hillside, and partly because it just looks right against a view lot. What doesn't change with the view is the physics: board and batten is a joint-heavy profile, with a vertical seam between every board and the batten that covers it, and each of those seams is a place water can try to work its way behind the wall. On a site as exposed as Cap Sante, how those seams are built matters more than almost anything else about the job.
We install James Hardie fiber cement board and batten exclusively, and every fastening pattern, batten clearance, and flashing detail we use is built around what this specific hillside does to a wall over ten, twenty, and thirty years, not around what looks acceptable the day the crew packs up.

What Cap Sante's Exposure Demands from a Board & Batten Wall
Wind-Driven Rain Off the Marina and Channel
Homes on Cap Sante look out over the marina and the channel, and that same open water is what pushes rain sideways instead of letting it fall straight down. A vertical siding profile gives wind-driven rain a lot of joint length to test — every batten seam running the height of the wall is a seam that has to be built to shed water under pressure, not just under a light, calm rain. Battens that are caulked shut instead of properly lapped and back-primed turn from a design feature into a wick that pulls moisture toward the fastener line instead of keeping it out.
Salt Air and Fastener Corrosion
The steady salt exposure that comes with living above a working marina is hard on any exposed metal, and board and batten uses more fasteners per square foot than a standard lap profile because both the boards and the battens each need to be secured independently. Getting the fastener spec right — corrosion-resistant, correctly sized, correctly spaced — carries more weight on this profile than on almost any other siding style, and it carries even more weight on a lot with this kind of direct water and salt exposure.
Moss on Shaded, View-Facing Walls
Not every wall on a Cap Sante lot faces the water. North-facing and tree-shaded elevations hold dampness far longer than the view-facing side, and that dampness is exactly what moss and mildew need to take hold. A batten set tight against a board with no room for air movement traps moisture right where it can't dry, which over a few wet seasons shows up as staining, softened substrate, and paint failure right along the seam.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, simply because there's more seam length and more exposed edge per square foot than a lap profile has. That's part of why we don't offer LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. Those are legitimate products, and other contractors install them competently — but on a profile with this many joints, on a hillside this consistently exposed to salt and wind-driven rain, we standardized on one system we're willing to stand behind completely.
| Material | Behavior at Batten Seams | Maintenance in This Exposure | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss, salt, and fading | 30+ years with proper install |
| LP SmartSide (engineered wood) | More sensitive to moisture at cut edges and fastener holes | Moderate; edge sealing needs ongoing upkeep | 15-25 years, exposure-dependent |
| Vinyl | Can warp, fade, or gap at battens under wind and salt exposure | Low, but hidden moisture problems are hard to catch early | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High; recurring repainting or resealing cycle | 15-25 years with consistent upkeep |
James Hardie's fiber cement core doesn't expand and contract with moisture the way wood-based products do, which is exactly the property that matters most on a profile built entirely from vertical seams. The factory-applied ColorPlus finish also means the cut edges we prime on site are the exception rather than the rule, unlike field-painted siding where the paint job's durability depends on every board face holding up outdoors on its own.
What a Correct Board & Batten Install Actually Involves
The finished look of board and batten is simple — vertical boards, battens over the seams — but a correct install has a lot going on behind that surface, especially on an exposed lot:
- House wrap or weather-resistive barrier installed and lapped correctly before any siding goes up
- A drainage gap or rainscreen behind the siding so moisture that does get past the surface can dry out instead of sitting against the wall
- Boards fastened with corrosion-resistant fasteners at the manufacturer's specified spacing, not just enough to hold the material up
- Battens set with the clearance Hardie's install spec calls for, rather than caulked tight, so the wall can shed water instead of trapping it
- Properly 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 preserved by cutting boards face-down and priming any field-cut edges before installation
Skip any one of these and the wall can still look right for a season or two. The problems that follow — staining at the seams, softened wood at the base, paint failure along the battens — take a few wet winters to show up, which is exactly why they're easy for a rushed install to get away with until the homeowner is the one dealing with it.
Our Process for a Cap Sante Board & Batten Project
Walkthrough and Assessment
We start by walking the specific walls involved — which ones face the water and take direct wind-driven rain, which are shaded and slow to dry, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes up. Board and batten installed over a wall with hidden rot or poor drainage just buries the same problem under new material.
Detailing the Plan Before Install Day
We work out batten spacing, corner details, and how the siding meets windows, trim, and rooflines before any material gets cut. On a profile with this many seams, and on a lot this exposed, sorting the details on paper first avoids the kind of field improvisation that tends to be 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 standard. That's what keeps the manufacturer's warranty intact, and it's why the wall performs the way it's supposed to for decades rather than a handful of years.
Final Walkthrough
We walk the finished job with you, cover what the (very short) maintenance list for board and batten actually looks like, and make sure you know what a healthy seam looks like if you ever want to check the wall yourself.
Why Hire a Crew That Already Works Cap Sante
Board and batten rewards experience with a specific site's exposure in a way a lot of siding profiles don't, because the failure points are subtle and slow to show up. A crew that's already worked homes up on Cap Sante through more than one wet season has seen which orientations need extra attention because of direct water exposure or shade, how much batten clearance actually holds up in a spot this consistently damp versus what a generic install guide assumes, and where a rainscreen gap earns its keep versus where it's optional. That kind of judgment doesn't show up on a spec sheet, and 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.
It also means fewer surprises on access and site logistics — hillside lots above the marina often mean tighter driveways, retaining walls, and staging challenges that a crew unfamiliar with the area has to figure out on the fly instead of planning for up front.
Cost Factors for Board & Batten in This Area
Board and batten typically costs more per square foot than standard lap siding, mainly because of the added material — battens on top of boards — and the extra labor involved in fastening and detailing two layers instead of one. Beyond that base cost, a few things move the price on a given Cap Sante home:
| Factor | Why It Matters |
|---|---|
| Wall height and complexity | More corners, dormers, and transitions mean more cuts and flashing details |
| Existing wall condition | Rot or 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 |
| Trim and window detailing | More openings mean more flashing and finish work around each one |
| Site access | Hillside lots, retaining walls, or limited driveway space can add labor and staging time |
We'll walk your specific property and give you real numbers rather than a rough estimate based on square footage alone — two homes on the same hillside can have very different board and batten costs depending on how many of these factors are actually in play.
Getting It Right the First Time
Board and batten isn't a forgiving profile to redo. Because the battens cover the seams between boards, correcting a bad install usually means pulling battens, boards, or both, rather than a simple patch job. That's part of why we treat the planning and detailing phase as seriously as the installation itself — the cost of getting it right the first time is a lot lower than the cost of tearing out a wall that was installed wrong, especially on a lot with the exposure Cap Sante homes deal with.
