Birch Bay Board & Batten and Ferndale's Farmhouse Character
Board and batten shows up more in Ferndale than in almost any other part of Whatcom County, and there's a straightforward reason for it: the profile's vertical lines and clean, simple shadow lines fit the working-farmhouse look that defines a lot of this area. Whether it's a century-old farmhouse getting a full re-side, a barn-style shop building, or a newer home on a subdivided piece of what used to be open field, board and batten reads as authentic here in a way it doesn't everywhere. That's the appeal side of the equation.
The other side is that board and batten is a joint-heavy profile. 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 Ferndale's climate — driving rain off the Strait of Georgia, salt-tinged air, and a moss season that runs most of the year on shaded and north-facing walls — puts real, sustained pressure on those seams. 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 climate does to a wall over decades, not around what looks tidy on the day the crew packs up.
What Ferndale's Climate Asks of a Board & Batten Wall
Wind-Driven Rain Across Open Ground
A lot of Ferndale sits on flatter, more open land than the hillsides and wooded lots common closer to Bellingham — agricultural fields, wide subdivided lots, and properties with fewer mature trees breaking the wind. That openness means storms coming off the water hit walls with less to slow them down first, and wind-driven rain lands on vertical board and batten seams at more of an angle than it would on a sheltered lot. A batten that's caulked tight instead of properly lapped with room to breathe becomes a direct path for that rain to reach the fastener line.
Salt Air Reaches Farther Than People Expect
Ferndale sits a few miles inland from Birch Bay and the Strait of Georgia — close enough that salt-tinged marine air still reaches most of the town, but far enough that some homeowners assume they're out of range. They're usually not. Board and batten uses more fasteners per square foot than a standard lap profile, since both the boards and the battens over them need to be secured, which means getting fastener corrosion resistance right matters more on this profile than on most others, even a few miles back from the water.
Moss on Shaded, Slow-Drying Walls
Older farmhouses and properties with outbuildings often have walls that sit in shade for a good part of the day — from a barn, a windbreak of trees, or simply north-facing orientation on a rural lot. Those walls hold moisture longer, and that's exactly the condition moss and mildew need to take hold. A batten set tight against a board with no drainage gap behind it traps that dampness right where it can't dry out, which over a few wet seasons shows up as staining at the seams and paint failure along the battens.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, because it has more seams and more exposed edge per square foot than a lap profile. 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 climate this consistently wet, we standardized on one system we trust completely.
| Material | Behavior at Batten Seams | Maintenance in This Climate | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss 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 regular upkeep | 15-25 years, climate-dependent |
| Vinyl | Can gap or distort at battens with temperature swings; seams less rigid | Low, but hidden moisture behind panels is hard to catch | 20-30 years, variable |
| Cedar / primed wood | Absorbs moisture readily at every seam without consistent 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 a wood-based product does, which is exactly the property that matters most on a profile built entirely from vertical seams. James Hardie's factory-applied ColorPlus finish also means the cut edges we prime on site are the exception rather than the rule, unlike a field-painted material where the paint on every board face is doing all the work outdoors.
What a Correct Board & Batten Install Actually Involves
The finished look — vertical boards, battens over the seams — is simple, but getting a board and batten wall to actually perform in this climate involves more than most people expect:
- House wrap or weather-resistive barrier installed and correctly 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, not just enough to hold the piece up
- Battens set with the clearance James Hardie's install spec calls for, rather than caulked tight, so the wall can actually shed water
- Properly flashed and lapped transitions at windows, doors, corners, and the base of the wall, where a vertical run meets a horizontal surface
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before they go up
Skip any of these and the wall can still look fine for a season or two. The problems that show up when they're skipped — staining at seams, soft spots near the base, paint failure along the battens — take a few wet winters to appear, which is exactly why they're easy for a rushed install to get away with until it's the homeowner dealing with the fallout.
Our Process for a Ferndale Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved — which face the weather most directly, which sit in shade from outbuildings or trees and dry slower, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes up. On an older farmhouse especially, board and batten over hidden rot just buries the same problem under new material.
Planning the Details 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, settling those details on paper first avoids field improvisation — which is usually where corners get cut on a rushed job.
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 also what keeps the wall performing the way it's supposed to for decades rather than 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 a healthy wall looks like if you ever want to check it yourself.
Why Hire a Crew That Already Works Ferndale
Board and batten rewards experience with this specific area in a way a lot of siding decisions don't, because the failure points are subtle and slow to show up. A crew that's installed this profile across Ferndale's mix of older farmhouses, open agricultural lots, and newer subdivisions has already seen which orientations need extra attention because of shade and windbreaks, how much batten clearance actually holds up in a climate this damp versus what a generic install guide suggests, and where a rainscreen gap earns its keep on an exposed, open lot versus a sheltered one. That's 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 on top of boards — and the extra labor involved in fastening and detailing two layers instead of one. Beyond that baseline, a few things move the number on a given Ferndale property:
| Factor | Why It Matters |
|---|---|
| Wall height and roofline complexity | More gables, dormers, and transitions mean more cuts and flashing details |
| Existing wall condition | Older farmhouses often need sheathing or framing repair found once old siding comes off |
| 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 | Rural lots, outbuildings, and long driveways can add setup and staging time |
We'll walk your specific property and give you real numbers rather than a rough estimate off square footage alone — two homes of similar size can land at 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 is not a forgiving profile to fix after the fact. Because the battens cover the seams between boards, correcting a bad install usually means pulling battens, boards, or both, rather than a quick 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 put up wrong.
If you're weighing board and batten for a home in Ferndale — whether it's a farmhouse-style re-side or a new build — we're happy to walk the property, talk through what your specific walls need given their orientation and exposure, and give you a straightforward, no-pressure estimate.
