Lynden Siding Board & Batten Siding Built for Custer's Open Ground
Board and batten shows up a lot on the farmhouses, newer builds, and outbuildings scattered across Custer, and it's easy to see why. The vertical lines fit the area's mix of working agricultural land and newer residential construction, and it reads as clean and substantial rather than trendy. What most homeowners don't think about until they're comparing bids is that board and batten is a joint pattern before it's a look. Every seam where a batten covers the gap between two boards is a place water can try to work its way behind the wall, and on the flat, wind-exposed ground around Custer, those seams get tested harder than they would in a more sheltered setting.
We install James Hardie fiber cement board and batten exclusively. This page is about what that profile specifically needs to hold up on a Custer property, not a general overview you'd get from a page written for anywhere in the Pacific Northwest.
What Custer's Climate Asks of a Board & Batten Wall
Wind-Driven Rain Across Open Fields
Custer sits on flat, largely open agricultural land with fewer hills and tree lines to slow incoming weather than a more built-up or forested part of Whatcom County. That means storms coming off the water arrive with less to break their momentum, and rain regularly hits walls at an angle instead of falling straight down. A vertical profile like board and batten has more running seam length exposed to that wind-driven rain than a horizontal lap profile does, so how each batten is set and gapped matters more here than it would on a sheltered lot.
Salt Air Reaching Inland Properties
Custer isn't a waterfront town, but it's close enough to the Salish Sea that salt-tinged air still reaches properties well back from the coast, especially during winter storms pushed in off the water. Salt exposure works on exposed fasteners and factory finishes gradually, over years rather than weeks, which is exactly the kind of slow damage that's easy to ignore until a wall needs attention sooner than it should.
A Moss Season That Runs Most of the Year
Mild temperatures and consistent moisture keep moss and mildew active across most of the calendar on shaded, north-facing, and tree-lined sections of a property. Custer has plenty of properties with exactly that mix of open field and windbreak tree lines, and any spot where the wall stays damp longer than the rest is a spot where organic growth gets a foothold. On a board and batten wall, a batten set tight against its board with no room to dry out is one of the more common places that happens.
Why Product Choice Matters More on This Profile
Board and batten has more seams and roughly twice the fasteners per square foot of a standard lap profile, since both the boards and the battens covering them have to be secured. That means whatever weaknesses a siding material has get more chances to show up. It'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 — we made a professional decision that on a profile this seam-heavy, in a climate this consistently wet and wind-exposed, we'd rather stand fully behind one material system than offer a cheaper option that shifts long-term maintenance risk onto the homeowner.
| Material | Behavior at Batten Seams | Maintenance Around Custer | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss and salt-air fading | 30+ years with correct install |
| LP SmartSide (engineered wood) | Cut edges and fastener holes are moisture entry points | Moderate to high; cut edges and caulk need regular checks | 15-25 years, climate-dependent |
| Vinyl | Seams can gap or bow under wind load and temperature swings | Low visible upkeep, but hidden moisture is hard to catch | 20-30 years, variable |
| Cedar | Absorbs moisture at every seam without a consistent finish schedule | High; recurring painting or staining | 15-25 years with consistent upkeep |
Fiber cement's inorganic core doesn't expand and contract with moisture the way wood-based products do, which matters most on a profile built almost entirely out of vertical seams. Hardie's factory-applied ColorPlus finish also means field priming is limited to cut edges, not something every board face depends on the way a site-painted material does.
What a Correct Board & Batten Install Actually Involves
The finished look is simple: vertical boards, battens over the seams. What's happening behind that surface, on a job done right, is a lot more involved:
- A properly lapped house wrap or weather-resistive barrier installed before any siding goes up
- A drainage gap or rainscreen behind the siding so moisture that gets past the surface can dry instead of sitting against the wall
- Corrosion-resistant fasteners placed at the manufacturer's specified spacing, not a rough approximation
- Battens set with the clearance Hardie's install spec calls for, not caulked tight against the board
- Correctly flashed and lapped transitions at windows, doors, corners, and the base of the wall
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming every field-cut edge before installation
Skip any one of these and the wall can still look fine on install day. The problems that come from skipping them — seam staining, soft spots low on the wall, paint failure along battens — take a wet season or two to show up, which is exactly why a rushed install can get away with it until the homeowner is the one dealing with the repair bill.
Our Process for a Custer Board & Batten Project
Walkthrough and Assessment
We start by walking the property and looking at which walls take the brunt of the weather, which are shaded by tree lines or outbuildings and slower to dry, and whether the existing wall assembly has any moisture issues that need addressing before new siding goes up. Installing over a wall with hidden rot just buries the same problem under new material.
Planning the Details Before Install Day
Batten spacing, corner treatment, and how the siding will meet windows, trim, and rooflines get worked out before crews start cutting material. On a profile with this many seams, planning ahead avoids the kind of on-the-fly decisions in the field that tend to be where corners get cut.
Installation to Manufacturer Spec
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 the reason the wall is built to perform for decades in this weather rather than just look right at handoff.
Final Walkthrough
We walk the completed job with you, explain what little maintenance board and batten actually requires with this material, 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 Custer
Board and batten rewards familiarity with a specific area's conditions more than most siding profiles, because the failure points are subtle and slow to appear. A crew that's already installed this profile on Custer's flat, open, agricultural land has seen which orientations need extra batten clearance because of unbroken wind exposure, which properties near tree lines or drainage ditches hold moisture longer than the rest of the lot, and where a rainscreen gap actually earns its keep in this specific setting versus a more sheltered neighborhood closer to town. That judgment 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 runs more 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. A few factors move the price on a given Custer property beyond that baseline:
| Factor | Why It Matters |
|---|---|
| Wall exposure and wind loading | Open, unsheltered walls may need tighter fastening and clearance detailing |
| 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 |
| Access and site layout | Outbuildings, fencing, or long driveways can add setup and material staging time |
We'll walk your specific property and give you real numbers based on what's actually there, since two homes with similar square footage can carry very different board and batten costs depending on exposure and existing wall condition alone.
Getting It Right the First Time
Board and batten isn't a forgiving profile to correct after the fact. Because the battens cover the seams, fixing a bad install usually means pulling battens, boards, or both, rather than a quick patch. That's why we treat planning and detailing with the same seriousness as the install itself — it costs a lot less to get it right the first time than to tear out and redo a wall that was rushed.
