Lynden Siding Board & Batten Siding for Ferndale Homes
Ferndale sits close enough to Bellingham Bay and the Strait that its homes take on more marine exposure than towns further inland, and that shows up clearly on any wall covered in board and batten. The vertical profile has become a favorite around Whatcom County for the way it reads — modern on newer construction, farmhouse-classic on older homes — but it's also a profile with more seams per square foot than standard lap siding, and every one of those seams is a place water can try to work its way behind the wall. In a place where salt-tinged air, wind-driven rain, and a moss season that runs most of the year are just normal weather, how those seams are built matters as much as which siding goes up.
We install James Hardie fiber cement board and batten exclusively, and we build every joint, fastening pattern, and flashing detail around what Ferndale's climate does to a wall over ten, twenty, and thirty years — not around what looks good on the day the scaffolding comes down.
What Ferndale's Climate Asks of a Board & Batten Wall
Wind-Driven Rain Off the Bay
Rain in Ferndale rarely falls straight down. Open water to the west means fewer windbreaks, and wind routinely pushes rain sideways into whatever siding is in its path. A vertical profile with battens running the full height of a wall gives that driving rain a lot of joint length to test. A batten that's caulked tight instead of properly lapped, or fastened without the clearance it needs, turns from a decorative strip into a place water collects instead of sheds.
Salt Air and Fastener Corrosion
The steady salt exposure this close to the water is hard on anything metal. Board and batten already uses more fasteners per square foot than lap siding, since both the boards and the battens have to be secured, so a corrosion-resistant fastener spec carries more weight on this profile than on most others. Get it wrong and rust streaks and loosening fasteners show up years before they should.
A Moss Season That Doesn't Really End
Shaded and north-facing walls around Ferndale hold moisture longer than sun-exposed ones, and that's exactly the condition moss and mildew need to establish. A batten set flush against a board with no way for trapped moisture to dry out becomes a long-term host for both — and once moss gets a foothold at a seam, it holds water against the wall behind it, which is a slow but steady path toward soft substrate and finish failure.
Why Product Choice Matters More on This Profile
Board and batten magnifies whatever weaknesses a siding material already has, simply because there's more seam length and more exposed edge per square foot than on a standard lap wall. That's a real 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 well — we made a professional decision that on a profile with this many joints, in a climate this consistently wet and salt-exposed, standing behind one system we trust completely serves our customers better than adding options that shift maintenance risk onto them down the road.
| 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 upkeep | 15-25 years, climate-dependent |
| Vinyl | Can warp or gap at battens with temperature swings; 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; repainting or resealing on a recurring cycle | 15-25 years with consistent upkeep |
Fiber cement's dimensional stability is the property that matters most on a profile built entirely out of vertical seams — it doesn't expand and contract with moisture the way wood-based products do, so the joint that was tight on install day stays tight. James Hardie's factory-applied ColorPlus finish adds to that: the cut edges we prime on site are the exception, not the rule, unlike field-painted siding where the whole wall's finish depends on paint quality holding up against Ferndale's weather year after year.
What a Correct Board & Batten Install Actually Involves
The finished look of board and batten is simple — vertical boards, a batten covering each seam — but getting a wall like that to actually perform in this climate takes more than most people assume:
- 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 does get past the surface has somewhere to go instead of sitting against the sheathing
- 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 a vertical profile meets a horizontal surface
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before they go on the wall
Skip any one of these and the wall can still look right for a year or two. The problems that show up when corners get cut — staining at seams, soft spots near the base, finish failure along the battens — usually take a couple of wet seasons to surface, which is exactly why a rushed install can pass a first look and still fail the wall over time.
Our Process for a Ferndale Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved — which face the weather directly, which sit in shade and stay damp longer, 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 poor drainage just buries the same problem under new material instead of solving it.
Detailing the Plan Before Install Day
Batten spacing, corner details, and how the siding meets windows, trim, and rooflines all get worked out before crews start cutting material. On a profile with this many seams, planning those details on paper first avoids the kind of field improvisation that's 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 part of what keeps the manufacturer's warranty intact, and it's the main reason the wall performs the way it's supposed to for decades instead of 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 a healthy wall looks like if you ever want to check it yourself down the road.
Why Hire a Crew That Already Works Ferndale
Board and batten rewards experience with a specific climate more than most siding profiles do, because the failure points are subtle and slow to show up. A crew that's installed this profile around Ferndale through multiple wet seasons has already seen which wall orientations need extra attention because of shade and proximity to the water, how much batten clearance actually holds up in this level of dampness versus what a generic install guide assumes, and where a rainscreen gap earns its keep instead of being optional. That kind of judgment 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 of fastening and detailing two layers instead of one. Beyond the base material, a few things move the price on a given Ferndale 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 |
| Exposure and orientation | Walls facing the water or prevailing wind often warrant extra flashing attention |
We'll walk your specific home and give you real numbers rather than a rough estimate based on square footage alone — two Ferndale houses with the same footprint can land at 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 isn't a forgiving profile to redo. Because the battens cover the seams between boards, fixing a bad install usually means pulling battens, boards, or both, rather than a simple patch job. That's why we treat the planning and detailing phase of these projects as seriously as the install itself — getting it right the first time costs a lot less than tearing out a wall that was put up wrong.
