Lynden Siding Board & Batten Siding for Ferndale Homes
Board and batten has become one of the most requested looks in Whatcom County, and Ferndale homes wear it especially well — the vertical lines work on everything from a farmhouse-style rebuild near the water to a modern infill closer to town. But the look is only half the job. Ferndale sits close enough to Bellingham Bay and the Salish Sea that homes here deal with salt-laden air, long stretches of driving rain off the water, and a moss season that can run most of the year in shaded, north-facing spots. A board and batten system that isn't built and installed for that combination will show problems in a few years, not a few decades.
This page covers what board and batten siding actually is, what Ferndale's climate specifically demands from it, how we install it, and why we only do this work in James Hardie fiber cement — never wood, vinyl, or engineered wood board and batten.
What Board & Batten Siding Actually Is
Board and batten is a vertical siding pattern: wide flat panels (the "boards") installed with narrower strips (the "battens") covering the seams between them. It's one of the oldest siding patterns in American building — originally a practical way to cover gaps in vertical wood plank walls — and it's had a strong resurgence because the clean vertical lines read as both traditional and modern, depending on the trim and color choices around it.
The pattern is used two ways on Ferndale homes we work on: as the siding for an entire elevation, or as an accent — a gable end, a porch surround, a dormer — paired with horizontal lap siding on the rest of the house. Both approaches are common, and both need to be built correctly, because an accent panel that fails lets water into the wall assembly just as easily as a full elevation would.
Why It's More Than a Style Choice
Vertical siding patterns handle water differently than horizontal lap siding. Lap siding is designed so each course sheds water onto the course below it, working with gravity. Board and batten relies on the seams between boards — covered by the battens — staying tight and properly flashed, because water runs straight down the face of the panel and along every seam it meets. Get the batten spacing, fastening, or flashing wrong, and you've built a direct path for water into the wall, not a shingled system that sheds it away.
What Ferndale's Climate Demands From This System
Salt Air and Marine Exposure
Ferndale's proximity to the bay means homes — especially those on higher ground or with west and southwest exposures — take on airborne salt that other Whatcom County towns further inland don't deal with as much. Salt accelerates corrosion on any exposed metal fastener, flashing, or trim piece, and it draws moisture, keeping wall surfaces damp longer than they'd otherwise be. Any board and batten system near the water needs corrosion-resistant fasteners and flashing details, full stop.
Driving Rain and Wind-Driven Moisture
Storms coming off the water don't just fall straight down — wind pushes rain sideways into wall assemblies, and vertical board and batten seams are directly in the path of that wind-driven moisture. This is where installation quality matters more than material choice: a batten that's face-nailed without proper blocking, or a seam without a drainage gap behind it, will let wind-driven rain track behind the siding during a hard blow.
Moss and Prolonged Dampness
Shaded elevations, tree-lined lots, and north-facing walls around Ferndale hold moisture long after a storm passes, and moss takes hold anywhere organic buildup sits against a damp surface. Moss isn't just cosmetic — it holds water against the siding face and, over time, against fastener heads and seams, extending how long every surface stays wet after each rain event.
Why We Install James Hardie — Not Wood, Vinyl, or Engineered Wood Board & Batten
Board and batten is available in several materials, and each one gets used successfully somewhere. But for Ferndale's specific combination of salt air, wind-driven rain, and long damp shoulder seasons, we've standardized on James Hardie fiber cement panels and battens because of how the material itself behaves — not because of marketing.
Wood board and batten is genuinely handsome and it's the historical original for this pattern, but it's also organic material sitting in a climate that keeps it wet for long stretches. That means real, recurring maintenance — repainting, caulk renewal, and watching for rot at the base and around penetrations — or the wood pattern starts showing damage sooner than most homeowners expect. Vinyl board and batten is low-maintenance and inexpensive, but it's a thin plastic product that expands and contracts significantly with temperature swings, which stresses seams over time, and it doesn't hold up structurally the way a rigid panel does in wind events. Engineered wood (treated wood-strand) products have improved a great deal, but they're still wood-based, meaning they're dependent on an intact factory coating and correct field sealing at every cut edge to resist moisture — a single missed cut edge is a failure point.
James Hardie fiber cement doesn't rot, doesn't support moss growth the way organic siding can, and isn't affected by moisture swelling or insect damage. It's non-combustible, which matters given Whatcom County's dry-season wildfire risk in surrounding areas. And it carries a factory-applied ColorPlus finish engineered to hold color and resist the fading that comes with year-round UV and salt exposure — something field-applied paint on wood or engineered wood can't match over the same span of years.
Material Comparison for Ferndale's Climate
| Material | Moisture / Moss Resistance | Maintenance Burden | Fire Resistance |
|---|---|---|---|
| James Hardie fiber cement | High — doesn't rot or swell; factory finish resists moss staining | Low — periodic rinsing and caulk checks | Non-combustible |
| Wood (cedar) | Moderate — needs sealed finish and airflow to avoid rot | High — repainting/staining on a recurring cycle | Combustible |
| Vinyl | Moderate — doesn't rot but seams can loosen with thermal movement | Low — but limited repair options once damaged | Combustible, softens under heat |
| Engineered wood (treated strand) | Moderate — dependent on intact factory coating and sealed cut edges | Moderate — cut-edge sealing and coating checks | Combustible |
What a Correct Board & Batten Installation Involves
The material is only as good as the installation behind it. On every board and batten project, correct installation means:
- A drainage gap (rainscreen) behind the panels so any moisture that does get past the face can drain and dry instead of sitting against the wall sheathing
- Corrosion-resistant fasteners rated for the exposure — especially important given Ferndale's salt air
- Battens and panel edges fastened per James Hardie's engineering specs for reveal, fastener spacing, and edge distance, not "close enough" spacing
- Properly lapped and sealed flashing at every window, door, and roof intersection, since these are the highest-risk points for wind-driven rain intrusion
- Factory-cut or properly primed field cuts, so no raw edge is left exposed to moisture
- A clearance gap at the base of the wall and above roof lines, keeping the siding off grade and away from standing water or built-up debris where moss takes hold first
Skipping any one of these doesn't necessarily show up in the first year. It shows up in year three or five, as a stained seam, a soft spot at a corner, or moss creeping up from the base — problems that are far more expensive to fix once they're behind the wall than they would have been to prevent at install.
Our Process for Ferndale Board & Batten Projects
- On-site assessment — we look at wall condition, existing moisture damage, exposure direction, and whether the project is a full elevation or an accent application
- Wall preparation — repair or replace any compromised sheathing, install or verify the water-resistive barrier, and set up the drainage gap before any siding goes up
- Installation to spec — panels and battens fastened per James Hardie's published requirements, with flashing detailed at every penetration
- Finish and seal — factory ColorPlus finish means no field painting is required, but all field cuts and seams are sealed correctly
- Final walkthrough — we check reveal consistency, fastener placement, and flashing details before calling the job done
Cost Factors for Board & Batten Projects
| Factor | Why It Affects Cost |
|---|---|
| Condition of existing wall sheathing | Hidden rot or moisture damage found during tear-off adds repair scope before new siding goes up |
| Full elevation vs. accent application | Accent gables and dormers involve more cutting and detail work per square foot than open wall areas |
| Trim and corner detailing | Board and batten's clean lines depend on precise trim work at corners, windows, and rooflines |
| Access and site conditions | Steep lots, tree cover, or tight setbacks common around Ferndale can add scaffolding or staging time |
| Tear-off vs. new construction | Removing and disposing of old siding adds labor compared to installing on new framing |
Why a Crew That Already Works Ferndale Matters
Whatcom County's building departments and inspectors expect exterior work to meet code for the actual exposure conditions of the site, not a generic standard. A crew that regularly works Ferndale and the surrounding coastal areas already knows which elevations need extra flashing attention, where moss tends to establish first, and how local permitting works — that familiarity shows up in fewer surprises and fewer callbacks. It also means we're not learning the region's rain patterns and salt exposure on your project; we've already accounted for them in how we detail every seam and fastener.
Keeping Board & Batten Siding in Good Shape
- Rinse siding once or twice a year, especially on elevations facing the water, to clear accumulated salt residue
- Inspect caulking around windows, doors, and trim annually and have any cracked or missing sealant redone
- Keep gutters and downspouts clear so water isn't overflowing onto siding below
- Trim back vegetation and tree cover that keeps shaded elevations damp longer than necessary
- Watch the base of the wall for moss or algae buildup and clean it before it spreads upward
- Have any impact damage or loose battens repaired promptly rather than waiting for a bigger project
