Board & Batten Siding Around Cap Sante
Cap Sante sits at the edge of the water on Fidalgo Island, and homes in and around this part of Anacortes take weather straight off the harbor and the Salish Sea — wind, salt spray, and rain that rarely falls straight down. Board and batten has become a popular choice here because the vertical lines suit both the older character homes near the water and the newer builds going up around town. What a lot of homeowners don't think through until they're partway into a project is that board and batten is a joint pattern, not just a look. Every seam where a batten covers the gap between two boards is a place water can try to work its way behind the siding, and in this location, that seam gets tested harder than it would a few miles inland.
We install James Hardie fiber cement board and batten exclusively, and we build every seam, fastener pattern, and flashing detail around what a Cap Sante lot actually does to a wall over ten, twenty, and thirty years — not around what looks clean on the day the crew packs up.

What a Cap Sante Lot Asks of a Board & Batten Wall
Wind-Driven Rain Off the Water
Homes close to Cap Sante Marina and the harbor take rain at an angle more often than they take it straight down. A profile built entirely out of vertical seams gives that wind-driven rain a lot of joint length to push against. A batten that's caulked tight instead of properly lapped, or face-nailed without the clearance the manufacturer calls for, ends up pulling water toward the fastener line instead of shedding it back off the wall.
Salt Air and Fastener Corrosion
Proximity to saltwater is the defining fact of exterior work in this part of Anacortes. 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, so getting fastener spec right — corrosion-resistant, correctly sized, correctly spaced — carries more weight on this profile in this location than almost anywhere else in Skagit County.
Moss and Trapped Moisture on Shaded Walls
Not every wall around Cap Sante faces open water. Shaded, tree-covered, and north-facing sides of the same house hold dampness far longer, and that dampness is exactly what moss and mildew need to establish. A batten set tight against a board with no room to breathe traps that moisture right at the seam, which over a few wet seasons shows up as staining, softened substrate, and paint failure exactly where you can't easily see it forming.
Why Product Choice Matters More on This Profile, In This Location
Board and batten amplifies whatever weaknesses a siding material already has — more seams means more edges exposed to weather, and a harbor-facing lot means those edges see more of it. 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, in a spot this consistently wet and salt-exposed, we standardized on one system we trust completely.
| Material | Behavior at Batten Seams | Maintenance Near the Water | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists salt staining and moss | 30+ years with proper install |
| LP SmartSide (engineered wood) | More sensitive to moisture at cut edges and fastener holes | Moderate; edge sealing needs regular upkeep in salt air | 15-25 years, climate-dependent |
| Vinyl | Can warp or gap at battens under sun, wind, and cold cycling | Low upfront, but moisture problems behind it go unseen | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High; repainting or resealing on a recurring 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 made entirely of vertical seams. The factory-applied ColorPlus finish also means the cut edges we prime on site are the exception, not the rule, unlike field-painted products where every board face 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 has a lot happening behind that surface, and it's more involved than most other siding profiles:
- 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
- Corrosion-resistant fasteners at the manufacturer's specified spacing, not just enough to hold the boards up
- Battens set with the clearance Hardie's install spec calls for, not 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 steps and the wall can still look right for a year or two. The problems that show up when they're skipped — staining at seams, soft spots near the base, paint failure along battens — take a few wet seasons to surface, which is exactly why a corner-cutting install can get away with it right up until the homeowner is the one dealing with the repair.
Our Process for a Cap Sante Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved — which face the harbor and take direct weather, which are shaded and slower to dry, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes up. Installing board and batten over a wall with hidden rot or inadequate 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 will meet windows, trim, and rooflines before crews start cutting material. On a profile with this many seams, settling those details on paper first avoids field improvisation, which is usually where corners end up getting 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, not years.
Final Walkthrough
We walk the finished job with you, cover what maintenance actually looks like for board and batten (there's very little with this material, but it's worth knowing), and make sure you know what to look for if you ever want to check the wall yourself.
Why Hire a Crew That Already Works Cap Sante
Board and batten rewards experience with this specific location 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 installed this profile around Cap Sante and the rest of Anacortes through multiple wet seasons has already seen which walls need extra attention because of direct harbor exposure, how much batten clearance actually holds up in salt air versus what a generic install guide suggests, and where a rainscreen gap earns its keep versus where it's optional on a more sheltered wall. That's the kind of judgment that doesn't show up on a spec sheet, and it's the difference between a board and batten 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, mainly because of the added material — battens layered over boards — and the extra labor involved in fastening and detailing two layers instead of one. Beyond the base material, a few things move the price on a given Cap Sante home:
| Factor | Why It Matters |
|---|---|
| Exposure to the harbor | Direct water-facing walls need tighter fastener and flashing detail than sheltered walls on the same house |
| 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 |
| Access and site conditions | Tight lots or limited access near the water can add labor time |
We'll walk your specific home and give you real numbers rather than a rough estimate off square footage alone — two houses of the same size 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. That's part of why we treat the planning and detailing phase of these projects as seriously as the install 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 on a lot this exposed.
