Lynden Siding Board & Batten Siding in Bellingham — A Job Our Lynden Crew Knows Well
Bellingham sits about fifteen minutes south of our home base in Lynden, and board and batten is one of the profiles we get asked about most often once we're on that stretch of road. The vertical lines suit a lot of what's being built and renovated around Bellingham right now — modern infill near the bay, farmhouse-style remodels further out, older homes getting a facelift that keeps the lines simple. What board and batten actually is, underneath the look, is a joint system: narrow battens covering the seams between wider boards. Every one of those seams is a place water can try to work its way behind the wall, and in a climate that mixes salt-tinged marine air with wind-driven rain and a moss season that barely takes a break, how those seams are built matters as much as which siding shows up on the invoice.
We install James Hardie fiber cement board and batten exclusively, and we've built our process around what Bellingham's specific weather does to a vertical-seam wall over ten, twenty, and thirty years — not around what looks tidy on the day the scaffolding comes down.
What Bellingham's Climate Asks of This Profile
Wind Off the Bay Pushes Rain Sideways
Bellingham's proximity to the water means rain rarely falls straight down here — wind off Bellingham Bay and the Salish Sea drives it in at an angle, and a vertical siding profile hands that wind-driven rain a lot of joint length to test. A batten that's caulked tight instead of properly lapped with the clearance the manufacturer calls for doesn't shed that water; it holds it against the wall.
Salt Air Shortens the Life of the Wrong Fasteners
Board and batten uses noticeably more fasteners per square foot than standard lap siding, since both the boards and the battens over them need to be secured. In a climate with steady salt exposure off the water, that means fastener spec — corrosion resistance, size, spacing — carries more weight on this profile than it would on a plainer one, and it's an easy detail for a rushed crew to under-spec.
Moss Behind the Battens, Not Just on the Roof
Homes on shaded lots or under tree cover around Bellingham hold moisture longer than sun-exposed ones, and that dampness is exactly what moss and mildew need to take hold. A batten set tight against its board with no room to breathe traps that moisture right at the seam, which shows up over time as staining, softening substrate, and paint failure that starts at the joint line and spreads.
Why We Only Install James Hardie on This Profile
Board and batten is less forgiving of a weak material than most siding profiles, simply because it has more seams and more exposed edge per square foot of 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 plenty of contractors install them well. We made a professional decision that on a profile built entirely around vertical joints, in a climate this consistently wet and salt-influenced, we'd rather stand fully behind one system than offer a lower-cost option that quietly shifts maintenance risk onto the homeowner a few winters down the road.
| Material | Behavior at the Batten Seam | Upkeep in Bellingham's Climate | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; resists swelling or cupping at the joint | Low — factory finish resists moss and fading | 30+ years with correct install |
| LP SmartSide (engineered wood) | More vulnerable at cut edges and fastener penetrations | Moderate — edge sealing needs periodic attention | 15-25 years, climate-dependent |
| Vinyl | Can gap or distort at battens with temperature swings | Low visible upkeep, but hidden moisture issues are hard to spot | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High — recurring painting or resealing cycle | 15-25 years with consistent maintenance |
Fiber cement's core doesn't expand and contract with moisture the way wood-based products do, which is precisely the property that matters most on a profile made up almost entirely of vertical joints. The factory-applied ColorPlus finish also means we're only priming field-cut edges on site, not relying on paint quality across the whole wall face the way a field-finished material requires.
What a Correct Board & Batten Install Actually Involves
The finished look is simple: vertical boards, battens over the seams. What holds that look together for decades is less visible.
- 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 sheathing
- Corrosion-resistant fasteners at the spacing James Hardie's install spec calls for, not a generalized "enough to hold it" pattern
- Battens set with proper clearance rather than caulked flush, so the wall can shed water instead of trapping it at the seam
- Correctly flashed and lapped transitions at windows, doors, corners, and the base of the wall, where the vertical run meets a horizontal surface
- ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before they go up
Miss any one of those steps and the wall can still look right for a season or two. The problems that follow — seam staining, soft spots near the base, paint failure tracking along the battens — take a few wet winters to surface, which is exactly why a corner-cutting install can pass a first inspection and still fail the homeowner later.
Our Process on a Bellingham Job
Walking the Property First
We start by looking at the specific walls in play — which face the weather most directly, which sit shaded and slow to dry, and whether the existing wall assembly already has moisture problems that need addressing before new siding goes up. Board and batten over a wall with hidden rot doesn't fix that wall, it just buries the problem under new material.
Planning Batten Layout and Detailing Before Cutting Begins
Batten spacing, corner treatment, and how the siding meets windows, trim, and rooflines get worked out before crews start cutting. On a profile with this many seams, sorting that out on paper first avoids the kind of field improvisation that's where corners tend to get cut on a job.
Installing to Manufacturer Spec, Not a Generic Standard
Every fastener, gap, and flashing lap follows James Hardie's published requirements for this climate zone. That's what keeps the manufacturer's warranty intact, and it's also just what makes the wall perform the way it's designed to for decades instead of years.
Final Walkthrough Before We Leave
We walk the finished job with the homeowner, explain what little maintenance board and batten actually needs, and make sure you know what a healthy seam looks like if you ever want to check the wall yourself down the road.
Cost Factors for a Board & Batten Project in Bellingham
Board and batten generally runs higher per square foot than standard lap siding, mostly because of the added batten material and the extra labor of fastening and detailing two layers instead of one. Beyond that baseline, a few things move the number on a given Bellingham home:
| Factor | Why It Moves the Price |
|---|---|
| Wall height and complexity | More corners, dormers, and transitions mean more cuts and flashing details |
| Condition of the existing wall | Rot or moisture damage found during tear-off needs repair before new siding goes on |
| Batten spacing and reveal | Tighter spacing means more material and more fastening labor |
| Window and trim detailing | More openings mean more flashing and finish work around each one |
| Site access | Steep lots, tight setbacks, or limited staging space can add labor time |
We give real numbers off a walkthrough of your specific home rather than a square-footage rule of thumb — two Bellingham houses with identical square footage can land on very different board and batten quotes depending on how many of these factors are in play.
Why a Crew That Splits Time Between Lynden and Bellingham Matters
We're based in Lynden, and Bellingham is a regular part of our route, not an occasional trip. That matters on a profile like board and batten because the failure points are subtle and slow to show — the kind of thing you only really learn by installing the same profile across enough Bellingham homes, through enough wet seasons, to see which orientations need extra attention because of shade and tree cover, how much clearance a batten needs in air this consistently damp, and where a rainscreen gap earns its keep versus where it's optional. Lynden sits far enough inland that its exposure isn't identical to a lot on Bellingham Bay, and a crew that works both areas regularly carries that comparison with them onto every job — they know Bellingham's marine exposure isn't the same as their home turf, and they build accordingly instead of applying one generic approach everywhere.
Getting It Right the First Time
Board and batten doesn't forgive a bad install easily. Because the battens cover the seams between boards, correcting a mistake usually means pulling battens, boards, or both, rather than patching a visible problem. That's why we treat the planning and detailing phase with the same seriousness as the install itself — the cost of doing it right the first time is a lot smaller than the cost of tearing a wall back apart two or three years in.
