Board & Batten Siding for Custer Homes
Custer sits out in the flat agricultural land north of Ferndale, a few miles inland from the Salish Sea and the Strait of Georgia. Homes here don't take the direct salt spray a waterfront lot on Birch Bay or Drayton Harbor does, but they still sit in the path of marine air pushed inland on winter storms, driving rain with nothing on the open, flat terrain to slow it down, and a moss season that stretches across most of the year on shaded and north-facing walls. That's a demanding combination for any siding profile, but it's a particularly demanding one for board and batten, because board and batten is built almost entirely out of vertical seams. Every place a batten runs down a wall is a joint, and every joint is a place water can try to find its way behind the siding instead of running off it.
We install James Hardie fiber cement board and batten exclusively for homes in Custer. We narrowed to one system after watching, over years of work in this part of Whatcom County, which materials actually held up to sustained inland moisture and salt-tinged air on a profile with this many joints — and which ones quietly became a maintenance problem for the homeowner a few years down the road.

What Custer's Climate Asks of a Board & Batten Wall
Open, Flat Land and Wind-Driven Rain
Custer doesn't have much natural windbreak. The agricultural flatland that surrounds it means storms moving in off the water carry rain sideways into a wall rather than letting it fall straight down and run off. On a horizontal lap profile, that wind-driven rain still has to work against overlapping courses. On board and batten, it's working against a series of vertical seams running the full height of the wall — more total joint length for the water to test, and less margin for a batten that's caulked tight instead of properly lapped and set with the clearance the material needs to shed water on its own.
Marine Air Reaching an Inland Property
Being set back from the water doesn't take Custer out of reach of marine air. Salt-tinged moisture in the air still travels inland on storm systems, and it's hard on exposed metal over time — fasteners, flashing, hardware. Board and batten uses more fasteners per square foot than a standard lap profile, since both the boards and the battens covering their seams need to be secured, which means getting the fastener spec right carries more weight on this profile than on most others in this area.
Moss and Moisture Trapped at the Seams
Mild temperatures and near-constant dampness through fall, winter, and spring give moss and mildew a long growth season across Whatcom County, and shaded or tree-covered walls in Custer hold that dampness longer than sun-exposed ones. On board and batten, the risk isn't just surface growth — it's a batten installed tight against a board with no room to breathe, trapping moisture right at the seam where it can't dry out between storms. That's a slow path toward staining, softened substrate, and paint failure that starts at the joint and works outward.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, simply because it has more seams and more exposed edge than most other profiles. That's a real factor in why we don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar as board and batten in Custer. Those are legitimate products, and plenty of contractors install them competently. We made a professional decision that on a profile this dependent on how well its joints hold up over time, in a climate that doesn't let a wall dry out for long stretches of the year, one material system we trust completely serves a homeowner better than a lower-cost option that shifts maintenance risk onto them later.
| 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; cut-edge sealing needs upkeep | 15-25 years, climate-dependent |
| Vinyl | Can gap or warp at battens with temperature swings; seams less rigid | Low, but trapped moisture behind panels is hard to catch | 20-30 years, variable |
| Cedar | Absorbs moisture at every seam without regular sealing | High; recurring sealing or repainting 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 matters most on a profile built entirely around vertical joints. Hardie's factory-applied ColorPlus finish also means the only field-painted edges on the wall are the ones we cut and prime ourselves — not every board face, the way a site-finished material depends on paint holding up outdoors for decades.
What a Correct Board & Batten Install Actually Involves
The finished look is simple: vertical boards, battens covering the seams between them. What holds that look together for decades, in a climate like Custer's, is everything underneath it:
- A 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 can dry out instead of sitting against the wall
- Corrosion-resistant fasteners at the manufacturer's specified spacing — not just enough fasteners to hold the boards up
- Battens set with the clearance Hardie's installation spec calls for, rather than caulked tight, so the wall can shed water instead of holding it against the seam
- Properly flashed, lapped transitions at windows, doors, corners, and the base of the wall, where a vertical profile meets a horizontal surface
- ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before they go up
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 along the battens, soft spots near the base, paint failure at the seams — take a few wet seasons of Custer weather to surface, which is exactly why they're easy for a rushed install to get away with until the homeowner is the one living with it.
Our Process for a Custer Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved: which face the weather most directly, which are shaded and slow to dry, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes up. New board and batten over a wall with hidden rot just buries the same problem under a nicer surface.
Planning Before Install Day
Batten spacing, corner detailing, and how the siding will meet windows, trim, and rooflines all get worked out before crews start cutting material. On a profile with this many seams, deciding these 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. That's what keeps the manufacturer's warranty intact, and it's also just what makes the wall perform 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 a healthy wall looks like if you ever want to check it yourself down the road.
Repair, Partial Replacement, or Full Re-Side?
Not every board and batten problem on a Custer home calls for tearing the whole wall off. A section damaged by an impact, an isolated batten that's come loose, or trim that's failed around one window can often be repaired and matched into the existing siding. But if moisture has been tracking behind the wall for a while — which shows up as soft spots, persistent staining at multiple seams, or a wall assembly that's been holding onto dampness for more than a season — patching the visible symptom usually just delays a bigger job while the underlying damage keeps spreading. We'll tell you plainly which situation you're actually looking at before recommending either one.
Why Hire a Crew That Already Works Custer
Board and batten rewards experience with this specific area in a way a lot of siding profiles don't, because its failure points are subtle and slow to show themselves. A crew that's installed this profile on Custer properties through multiple wet seasons already knows which wall orientations hold moisture longest given the flat, open terrain, how much batten clearance actually earns its keep in air this consistently damp versus what a generic installation guide assumes, and where the fastener spec needs to be tighter because of marine air reaching this far inland. That kind of judgment doesn't show up on a spec sheet, and it's the real 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 Custer
Board and batten generally costs more per square foot than standard lap siding, mainly 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 price on a specific Custer 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 on |
| 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 and exposure | Open, rural properties can have different staging needs than an in-town lot |
Exact numbers depend on the specific property and how exposed it is, which is why we walk the home in person before giving a real figure instead of quoting off square footage alone.
Getting It Right the First Time
Board and batten isn't 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 job. That's why we treat the planning and detailing phase of a Custer board and batten project as seriously as the installation itself — getting it right the first time costs a lot less than tearing out a wall that was installed wrong and doing it again.
