Board & Batten Siding for Cap Sante Homes
Cap Sante sits up on the high ground above the marina, and that elevated, water-facing position is exactly why board and batten shows up so often on homes there — the vertical lines suit both the newer builds and the older farmhouse-style homes on the hill, and from that height the profile reads well against the view. But a home perched above Fidalgo Bay with an open line to the water isn't a gentle site to build a wall on. It catches more wind, more salt, and more driving rain than a lot tucked a few blocks inland, and board and batten is a profile that puts more seams in that wall's path than almost any other siding style. Every vertical joint between a board and its batten is a place water can try to work its way behind the siding, and on a lot this exposed, how those joints are built matters as much as what they're built out of.
We install James Hardie fiber cement board and batten exclusively, and on a Cap Sante project every seam, fastener, and flashing detail gets built around what this specific site does to a wall over ten, twenty, and thirty years — not around what looks tight on the day the crew packs up.

What Cap Sante's Climate Asks of a Board & Batten Wall
Wind-Driven Rain Off the Water
Homes on Cap Sante's hillside are among the more exposed properties in Anacortes, with weather coming straight off the water rather than filtered through a few blocks of neighboring rooftops and trees. That kind of exposure pushes rain sideways into a wall instead of letting it run straight down, and a vertical profile with battens running the full height of the siding gives wind-driven rain a lot of joint length to test. A batten that's caulked tight instead of properly lapped and back-vented becomes the exact spot where that wind-driven rain finds its way in.
Salt Air and Fastener Corrosion
Marine air off the marina and the channel is hard on any exposed metal, and it doesn't take a direct waterfront lot to feel it — the salt exposure carries well up the hillside. Board and batten uses more fasteners per square foot than a standard lap profile, since both the boards and the battens over each seam need to be secured, so getting fastener spec right — corrosion-resistant, correctly sized, correctly spaced — matters more here than it does on most other siding styles.
A Long Moss Season on Shaded Walls
Not every wall on a Cap Sante lot faces the open water. North-facing walls, and anything shaded by mature trees or a neighboring roofline, hold onto dampness far longer through Skagit County's long, wet stretch of the year — and that lingering moisture is exactly what moss and mildew need to take hold. A batten set tight against a board with no room for airflow behind it traps that moisture right where it can't dry, which over a few 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 it has more joints and more exposed edge than a standard lap wall. That's a big 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 seams, on a site this exposed to wind and salt, we standardized on one system we trust completely rather than offering something that shifts the maintenance burden onto the homeowner later.
| Material | Behavior at Batten Seams | Maintenance on an Exposed Lot | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss and salt-driven fading | 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 wind load and temperature swings | Low, but hidden moisture behind the panel is hard to catch | 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 |
Fiber cement's core doesn't expand and contract with moisture the way wood-based products do, which is exactly the property that matters most on a wall built entirely out of 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 materials where the whole board's finish depends on paint quality holding up against sun and salt year after year.
What a Correct Board & Batten Install Actually Involves
The finished look of board and batten is simple — vertical boards, battens covering the seams — but a correct install on a site like Cap Sante has more going on behind that surface than most other siding profiles:
- House wrap or weather-resistive barrier installed and properly lapped before any siding goes up
- A drainage gap or rainscreen behind the siding so moisture that gets past the surface can dry out instead of sitting against the wall
- Boards fastened with corrosion-resistant fasteners at the manufacturer's specified spacing, sized for this level of wind and salt exposure
- 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 and the wall can still look right for a season or two. The problems that show up when they're skipped — staining at the seams, soft spots at the base, paint failure along the 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 it.
Our Process for a Cap Sante Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved — which ones take the wind and rain head-on, 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. 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 meets windows, trim, and rooflines before crews start cutting material. On a profile with this many seams, and a site this exposed, settling the details on paper first avoids the kind of field improvisation that's 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 standard. That's part of what keeps the manufacturer's warranty intact, and it's why the wall performs the way it's supposed to for decades rather than years.
Final Walkthrough
We walk the finished job with you, cover what little maintenance board and batten actually needs, and make sure you know what to look for on your own walls going forward.
Why Hire a Crew That Already Works Cap Sante
Board and batten rewards familiarity 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 installed this profile on Cap Sante's hillside through more than one wet season already knows which orientations need extra fastener and flashing attention because of direct water exposure, how much clearance a batten actually needs on a lot this windy 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.
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 the base material, a few things move the price on a given Cap Sante home:
| Factor | Why It Matters |
|---|---|
| Wind and water exposure | Homes with direct exposure often need heavier fastening and flashing detail than sheltered lots |
| 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 | Hillside lots and limited staging space 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 on the same street can have very different board and batten costs depending on how many of these factors are in play.
Getting It Right the First Time
Board and batten is not 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 a Cap Sante project 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 site this exposed.
