Lynden Siding Board & Batten Siding for Custer Homes
Board and batten has a strong presence in Custer for a simple reason: it's a natural fit for the farmhouse and barn-style architecture that's common on this part of the county's rural landscape, and it reads just as well on a newer build going up on a cleared lot. But board and batten isn't just a look you pick off a brochure. It's a joint system — vertical boards with a narrow strip covering every seam — and each of those seams is a place water can try to work its way behind the wall. In a climate that hands Custer salt-tinged air off the nearby coastline, wind-driven rain most of the year, and a moss season that can stretch from fall through spring on shaded walls, how those seams are built matters as much as which siding goes up.
We install James Hardie fiber cement board and batten exclusively, and every fastening pattern, gap, and flashing detail on a Custer job is built around what this specific stretch of Whatcom County does to a wall over ten, twenty, and thirty years — not around what looks acceptable on the day the crew packs up.
What Custer's Climate Demands From This Profile
Salt Air and Fastener Corrosion
Custer sits close enough to saltwater that airborne salt is a real factor on exposed metal, and board and batten uses more fasteners per square foot than standard lap siding because both the boards and the battens each need their own fastening. Getting the fastener spec right — corrosion-resistant, correctly sized, correctly spaced — matters more on this profile than on almost any other siding style.
Wind-Driven Rain Against Vertical Seams
Rain in this part of Whatcom County rarely falls straight down for long. Storms moving through push it sideways, and a vertical profile with battens running full-height gives that wind-driven rain a lot of seam length to test. A batten that's caulked tight instead of properly lapped and gapped becomes a place for water to collect rather than shed.
A Long Moss Season on Shaded Walls
Rural Custer properties often carry mature trees, outbuildings, and open exposure that combine to keep certain walls damp far longer than others. North-facing and tree-shaded elevations hold moisture well into the year, and that's exactly the environment moss and mildew need. A batten set tight against its board with no room to breathe traps that dampness right where it can't dry, which over a few wet seasons shows up as staining, softened substrate, or paint failure right at the seam.
Why the Material Choice Matters More on This Profile
Board and batten magnifies whatever weaknesses a siding material already has, because it has more seams and more exposed material edge than a standard lap 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 other contractors install them competently — we simply made a professional call that on a profile with this many joints, in a climate this consistently wet and salt-exposed, one material system we trust completely serves Custer homeowners better than a lower-cost option that shifts the maintenance burden onto them a few years down the line.
| 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; exposed edges need ongoing sealing | 15-25 years, climate-dependent |
| Vinyl | Can warp or gap at battens under sun and cold; seams less rigid | Low, but hidden moisture problems 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 upkeep |
Fiber cement's core doesn't expand and contract with moisture the way wood-based products do, which is exactly the property that carries the most weight on a profile built almost entirely out of vertical seams. Hardie's factory-applied ColorPlus finish also means the cut edges we prime in the field are the exception rather than the rule, unlike a field-painted product where the entire wall's finish depends on paint holding up outdoors year after year.
What a Correct Board & Batten Install Actually Involves
The finished look is simple — vertical boards, battens over the seams — but there's a lot happening behind that surface on a job done right:
- House wrap or a weather-resistive barrier installed and lapped correctly 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 sheathing
- Boards fastened with corrosion-resistant fasteners at the spacing James Hardie specifies, not just enough to hold the piece in place
- Battens set with the clearance the install spec calls for, not caulked tight, so the wall sheds water instead of trapping it
- Properly flashed, 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 one of these steps and the wall can still look right for a season or two. The problems that follow — staining at the seams, soft spots near the base, paint failure along the battens — take a few wet winters to surface, which is exactly why a shortcut install can look fine on handoff day and still leave the homeowner with the bill years later.
Our Process for a Custer Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved on your property — which face the weather directly, which are shaded by trees or outbuildings and slower to dry, 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 just buries that problem under new material; it doesn't fix it.
Detailing the Plan Before Install Day
We work out batten spacing, corner details, and how the siding will meet windows, trim, and rooflines before crews start cutting material. On a profile with this many seams, settling those details on paper first keeps the crew from improvising in the field, which is where corners tend to get 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 what keeps the manufacturer's warranty intact, and it's why the wall is built to perform for decades instead of just looking good on move-out day.
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.
Keeping Board & Batten Looking Right Through Moss Season
James Hardie's factory finish and Custer's climate can coexist just fine, but a little seasonal attention keeps a wall looking its best for the long haul:
- A gentle rinse once a year on shaded or north-facing walls where moss and algae tend to establish first
- Keep gutters and downspouts clear so overflow doesn't run down the wall face and stay put at batten seams
- Trim back branches and vegetation near the house to let shaded walls get more sun and airflow
- Check caulking at window and door trim yearly — it's the one component that wears faster than the siding itself
- Skip the pressure washer on close settings; a soft wash protects the factory finish better than a blast that can drive water behind the boards
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 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 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 at tear-off needs repair before new siding goes up |
| Batten spacing and reveal | Tighter spacing uses more material and more fastening labor |
| Outbuildings and matching structures | Barns, shops, and detached garages common on rural lots add scope if included |
| Access and site conditions | Long driveways, rural setbacks, or uneven grade can add labor time |
We'll walk your specific property and give you real numbers rather than a rough estimate based on square footage alone — two homes with similar footprints can land at very different board and batten costs depending on how many of these factors are actually in play.
Why a Crew That Already Works Custer Matters
Board and batten rewards experience with this specific area in a way a lot of siding profiles don't, because the failure points are subtle and slow to show up. A crew that's installed this profile across Custer and the surrounding Whatcom County communities through multiple wet seasons already knows which orientations need extra attention because of shade and tree cover, 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 a rural property versus a tighter in-town lot. That kind of judgment doesn't show up on a spec sheet — 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. Being based nearby also means a shorter drive for a warranty check or a quick follow-up question, not a service call that has to be scheduled around a long trip out to the property.
