Blaine Exterior Board & Batten Siding for Cherry Point Homes
Cherry Point sits on open water along the Strait of Georgia, between Ferndale and Blaine, and it's a different kind of exposure than a lot of in-town Whatcom County properties see. Lots out here tend to be larger and more spread out, with fewer neighboring structures and less tree cover to break up wind coming straight off the water. That open exposure is part of why board and batten has caught on with homeowners in the area — the strong vertical lines suit both the working rural character of the area and the newer homes going up on waterfront and near-waterfront lots. But board and batten isn't just a look. It's a joint pattern, with a vertical seam running the full height of the wall behind every batten, and each one of those seams is a place water can try to get behind the siding. On a property this exposed to wind-driven rain and salt air, how those seams are built matters as much as which siding brand ends up on the invoice.
We install James Hardie fiber cement board and batten exclusively, and on a property in Cherry Point we build the fastening pattern, batten clearance, and flashing detail around what this specific stretch of Whatcom County coastline does to a wall over ten, twenty, and thirty years — not around what looks fine on installation day.
What Cherry Point's Climate Asks of a Board & Batten Wall
Wide-Open Exposure to Wind and Driving Rain
Without the windbreaks that denser, in-town neighborhoods get from surrounding houses and mature street trees, Cherry Point properties take wind-driven rain more directly and more often. A vertical siding profile gives that wind a lot of joint length to push against. A batten that's caulked tight instead of properly lapped and back-clearanced becomes a wick that pulls moisture toward the fastener line instead of shedding it back off the wall.
Salt Air Off the Strait
Homes this close to the Strait of Georgia deal with a steadier dose of salt-laden air than properties set further inland in the county. Salt speeds up corrosion on 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 their own fastening line. Getting the fastener spec right — corrosion-resistant, correctly sized, correctly spaced — carries more weight on this profile than on most others, and more weight in Cherry Point than it would a few miles inland.
A Long Moss Season on Shaded and North-Facing Walls
Mild temperatures and near-constant moisture give moss and mildew a growing season that runs most of the year on walls that don't get much direct sun. Rural lots with more tree cover and outbuildings casting shade see this show up earlier than open, sun-exposed walls. A batten installed tight against a board with no room to breathe traps that moisture right where it can't dry out, which is a slow path toward staining and paint failure right at the seam.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, because the joint count is higher and more material edge is exposed to weather. 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 seams, in a spot this exposed to salt air and driving rain, we made a professional call to build every job around one system we trust 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 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 | 15-25 years, exposure-dependent |
| Vinyl | Can warp or gap at battens under sun and wind load; seams less rigid | Low, but hidden moisture damage is hard to catch | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High; recurring repainting or resealing | 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 out of vertical seams. The 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 every board face out here depends on paint holding up against direct salt exposure.
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 on an exposed Cherry Point property has more going on behind that surface 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 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, not just "enough to hold it 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 and the wall can still look fine 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 appear on an exposed property like this, which is exactly why they're easy for a corner-cutting install to get away with until the homeowner is the one dealing with it.
Our Process for a Cherry Point Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved — which ones take wind and rain straight off the water, 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 property with this much open exposure, planning the details on paper first avoids the kind of field improvisation where corners tend to 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 part of why the wall performs the way it's supposed to for decades on an exposed site, not just 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 you're looking at if you ever want to check the wall yourself.
Why Hire a Crew That Already Works Cherry Point
Board and batten rewards experience with a specific piece of coastline 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 other Cherry Point and near-shoreline properties has already seen which orientations need extra fastening attention because of direct wind exposure, how much batten clearance actually holds up in a spot this open versus what a generic install guide suggests, and where a rainscreen gap earns its keep versus where it's optional. That's judgment that 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 Cherry Point property:
| 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 |
| Site exposure | Fully open, water-facing walls warrant closer fastener spacing and more careful flashing than sheltered elevations |
| Access and site conditions | Larger rural lots, longer driveways, or limited staging area can add labor time |
We'll walk your specific property and give you real numbers rather than a rough estimate off square footage alone — two homes with similar footprints can have very different board and batten costs depending on how many of these factors are in play, especially exposure.
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 these projects as seriously as the install itself — the cost of getting it right the first time on an exposed Cherry Point wall is a lot lower than the cost of tearing out one that was installed wrong.
