Ferndale Board & Batten in Custer: A Look That Fits the Landscape
Custer sits in the rural, coastal stretch of Whatcom County northwest of Ferndale, and a lot of the homes and outbuildings out here already lean toward a simple, vertical-lined look — barns, sheds, and farmhouses that board and batten siding was originally designed to protect. That history is part of why the style still reads so naturally on properties in this area. It's not a trend look bolted onto a house that doesn't suit it; it's a pattern that grew up in places a lot like this one.
But the same openness and tree cover that make Custer feel rural also expose homes to weather most subdivisions never deal with. Wide-open fields mean wind gets a running start before it hits a wall. Mature trees mean shade, damp bark, and moss spores drifting onto siding for months at a time. And the proximity to the water means salt is in the air more days than people realize. Board and batten looks great here — but only if it's built to handle what "here" actually throws at it.
What Custer's Climate Puts Vertical Siding Through
Salt Air and Corrosion
Homes in Custer sit close enough to the marine waters of Whatcom County that airborne salt is a real, if easy-to-miss, factor. It doesn't show up as an obvious event — there's no single storm to point to. It's a slow chemical drip: salt-laden air settles on siding and fasteners day after day, and over years it accelerates corrosion in anything that isn't rated for coastal exposure. Steel fasteners, unprotected trim nails, and cheap flashing all degrade faster here than they would forty miles inland.
Driving Rain and Wind-Driven Moisture
Vertical board and batten has more seams and more edges than a flat lap profile — every board-to-batten joint is a potential path for water if it isn't detailed correctly. Combine that with wind-driven rain coming off open fields, and any gap, under-caulked joint, or missing flashing becomes an invitation for moisture to get behind the cladding rather than run off the face of it.
Moss Season and Shaded Lots
Whatcom County's long wet season means moss isn't a once-a-year nuisance — it's closer to a standing condition on shaded, north-facing walls and anywhere tree canopy blocks direct sun. Moss holds moisture against the siding surface far longer than open air would, which matters most on a material that can't tolerate sustained dampness at its edges and fastener points.
How Board & Batten Siding Actually Works
Board and batten isn't a single product — it's an assembly. Wide vertical panels (or boards) are installed first, then narrower strips, called battens, are fastened over the seams between them. Done right, the battens do two jobs: they hide the panel joints, and they create the rhythm of vertical lines the style is known for. Underneath all of it should be a water-resistive barrier and, ideally, a rainscreen gap — a small air space that lets any moisture that does get past the cladding drain and dry out instead of sitting against the wall sheathing.
The details that separate a good board and batten job from a problem one are almost all invisible once the house is finished: how the WRB is lapped, where flashing is installed above openings and at horizontal transitions, how far battens are spaced from panel edges, and what fastener schedule was actually followed. None of that shows up in a driveway photo. All of it shows up in year eight or ten.
The Materials Homeowners Consider — and Why We Only Install One
When people start pricing board and batten, they usually run into three material options: wood, vinyl, and fiber cement. Each behaves differently once it's exposed to years of Whatcom County weather.
| Factor | Wood | Vinyl | Fiber Cement (James Hardie) |
|---|---|---|---|
| Moisture resistance | Absorbs water; swells, cups, and rots at edges without diligent upkeep | Doesn't rot, but seams and channels can trap moisture behind panels | Engineered to resist moisture damage; won't swell or rot |
| Salt air / coastal exposure | Finish breaks down faster near salt air, exposing bare wood | Can become brittle and discolor with UV and salt exposure over time | Formulated for coastal and marine climates; ColorPlus finish resists fading |
| Moss and mildew | Porous surface holds moisture, feeding moss and mildew growth | Moss grows on the surface but doesn't damage the material itself | Dense, engineered surface resists moisture retention that feeds growth |
| Maintenance | Repainting and caulk touch-ups every few years; ongoing rot checks | Low maintenance but panels can warp, crack, or fade unevenly | Factory-cured finish; periodic caulk and paint touch-up only where needed |
| Fire resistance | Combustible | Combustible; can melt or deform near heat | Non-combustible fiber cement |
| Typical lifespan (installed correctly) | 15-25 years before major refinishing or replacement | 20-30 years, but appearance often degrades before failure | 30-50 years with proper installation and basic upkeep |
This company installs James Hardie fiber cement exclusively — we don't offer wood, vinyl, LP SmartSide, or other fiber cement brands. That's a standard we hold across every job, not just because of how the material performs on paper, but because we've seen how it holds up in exactly the kind of coastal, moss-prone conditions Custer sees year after year.
James Hardie's Board & Batten System
James Hardie builds board and batten in two main ways: true panel-and-batten assemblies using HardiePanel vertical siding with separate battens, and pre-styled board and batten profiles from their Artisan and HardieTrim lines. Both use the same fiber cement core — engineered from cement, sand, and cellulose fiber — and both are available with the ColorPlus factory finish, which bakes color onto the material before it ever reaches the jobsite. That matters in Custer specifically: a factory-cured finish holds up against salt air and UV exposure far better than field-applied paint, and it means fewer repaint cycles over the life of the siding.
James Hardie also engineers its HZ5 and HZ10 product lines for different climate zones, accounting for moisture exposure and temperature swings common to the Pacific Northwest. For a property in Custer, that climate engineering isn't a marketing detail — it's the difference between siding that's designed for this weather and siding that merely tolerates it.
What Correct Installation Involves in Custer
Moisture Management First
Before a single panel goes up, the wall needs a continuous water-resistive barrier, properly lapped shingle-style so water sheds down and out rather than behind it. On exposed or rain-heavy elevations, a rainscreen gap between the barrier and the siding gives any moisture that does get through a way to drain and dry, instead of sitting against the sheathing where rot starts.
Fastening and Batten Spacing
Fasteners need to land in solid framing or proper backing at the spacing James Hardie specifies — not wherever is convenient. Battens need consistent spacing and depth so they actually cover the panel seams rather than leaving hairline gaps that widen over time as the house settles and moves with temperature changes.
Trim, Flashing, and Sealant Details
Every window, door, and horizontal transition needs flashing that directs water outward, not siding butted straight against the opening and caulked as an afterthought. Caulk is a backup, not a strategy — it fails years before flashing does.
A correct board and batten job on a Custer home should include:
- A fully lapped water-resistive barrier installed before any siding goes up
- A rainscreen air gap on rain-exposed and shaded elevations
- Fasteners driven to manufacturer spacing into solid backing, not just sheathing
- Consistent batten spacing that fully covers panel seams
- Proper flashing at every window, door, and horizontal siding transition
- Factory-finished (ColorPlus) panels and trim to reduce field paint touch-up
- Clearance between the siding's bottom edge and grade, decks, or hardscaping
Our Process for a Custer Project
We start with a walk-around of the specific property — checking existing sheathing condition, sun exposure and shade patterns, tree cover, and how exposed each elevation is to prevailing wind and rain. That assessment shapes decisions like where a rainscreen gap matters most and where extra flashing attention is needed.
From there, we remove the old siding down to the sheathing, inspect and repair any water damage we find before it gets covered up again, and install the water-resistive barrier and rainscreen components first. Only then do the Hardie panels and battens go up, fastened to spec, followed by trim, flashing, and caulking at every joint and opening. We finish with a walkthrough so the homeowner can see the work before we consider the job done.
Why Hiring a Crew That Already Works in Custer Matters
A lot of siding problems in this area trace back to installation crews applying a generic approach to a property that needed a coastal one. A crew that already works around Custer knows which elevations tend to hold moss, how much salt exposure a given lot actually sees based on its position and tree cover, and where driving rain tends to concentrate on a typical Whatcom County wall. That local familiarity shows up in small decisions — where to add extra flashing, where a rainscreen gap earns its keep, where fastener corrosion resistance actually matters — that a crew unfamiliar with the area might skip entirely.
It also matters after the job is done. A local crew can get back out to a Custer property quickly for a warranty check or a punch-list item, instead of a homeowner waiting on a company based well outside the area.
