Why Board & Batten Keeps Showing Up on Ferndale Homes
Board and batten is one of the oldest siding patterns in the Pacific Northwest, and it's having a real moment again — clean vertical lines, deep shadow reveals, and a look that works equally well on a farmhouse-style rebuild or a modern infill build near downtown Ferndale. It's a great fit for gable ends, dormers, and accent walls, and plenty of homeowners in Whatcom County are choosing it for full elevations too. The look is simple. Getting it to actually perform for 30+ years in this climate is not, and that's where a lot of board and batten jobs go sideways.

What "Board & Batten" Actually Means With Fiber Cement
Traditional board and batten was wide boards with narrow strips (battens) nailed over the seams to cover gaps and shed water. That worked reasonably well with solid wood, but wood moves — it swells, shrinks, and cups with the seasons, and every one of those seams is a place water can work its way behind the cladding. James Hardie's engineered board and batten panels solve the same visual problem with a material that doesn't move with humidity the way wood does, holds a straight line over time, and is backed by a manufactured, factory-controlled installation system rather than a field guess.
The Two Ways We Install It
- Hardie Board & Batten panels — pre-finished vertical panels with the batten lines built in, installed as a single system with proper flashing and fastening per Hardie's published instructions.
- HardiePanel with applied battens — smooth or textured vertical panels with separate batten strips fastened over the seams, giving more flexibility on reveal width and spacing for custom architectural looks.
Both use James Hardie's fiber cement substrate, which is non-combustible, doesn't rot, and won't absorb moisture the way wood or wood-composite battens do. That last point matters more here than in drier climates — Whatcom County gets a long stretch of wet months, and anything organic sitting against a wall in that kind of moisture is on borrowed time.
Why the Climate Here Is Unforgiving on Vertical Siding
Ferndale sits close enough to Bellingham Bay and the Salish Sea that salt-laden air is a real factor on fasteners, flashing, and any exposed metal — not just on waterfront lots. Add in driving rain that comes sideways off the water during winter storms, and a moss season that can run most of the year on north-facing and shaded walls, and you've got three separate stresses working on the same wall assembly at once. Vertical board and batten is more exposed to wind-driven rain than horizontal lap siding because the reveals and seams run with gravity instead of shedding water the way overlapping laps do naturally. That's not a reason to avoid the look — it's a reason the installation details matter more here than almost anywhere else in the state.
Where Board & Batten Installations Actually Fail
- Missing or undersized flashing at horizontal transitions, window heads, and butt joints — the single biggest cause of hidden water intrusion behind vertical siding.
- Battens fastened directly through both layers into sheathing without proper spacing, which traps moisture between the board and batten instead of letting the wall breathe.
- No rainscreen gap on walls that see sustained wet exposure, which is common on the north and west faces of Whatcom County homes.
- Fasteners that aren't corrosion-resistant for a coastal-influenced air environment, leading to streaking and eventual fastener failure.
- Caulk used as the primary water barrier instead of flashing — caulk fails; flashing doesn't, if it's installed correctly.
None of these are defects in the material. They're installation shortcuts, and they're the reason two board and batten jobs using the identical Hardie product can perform completely differently ten years down the road.
What Correct Installation Looks Like
| Step | Why It Matters Here |
|---|---|
| Weather-resistive barrier + rainscreen where the wall orientation calls for it | Gives driving rain somewhere to go instead of sitting against the panel |
| Manufacturer-specified flashing at every horizontal joint and penetration | The actual water management layer — not decorative |
| Batten fastening per Hardie's fastening schedule, not "close enough" | Keeps the assembly moving and draining the way it's engineered to |
| Stainless or coated corrosion-resistant fasteners | Salt air degrades standard fasteners faster than inland installations |
| Factory ColorPlus finish, field-touched only where cut | Keeps the finish uniform and warrantied, resists the moss-friendly moisture cycle |
Why We Only Install James Hardie for This Look
We get asked about board and batten in engineered wood, primed spruce, and vinyl vertical panel systems fairly often, because they're usually cheaper up front. We don't install them. Wood and wood-composite battens are exactly the kind of organic, moisture-absorbing material that struggles in a climate with this much sustained dampness and moss pressure — they're more prone to swelling, checking, and rot at the exact seams that vertical siding depends on to shed water. Vinyl vertical panels can work loose or warp under sun exposure and don't hold a crisp architectural line the way a rigid fiber cement panel does. James Hardie's fiber cement is non-combustible, dimensionally stable, holds its factory finish for decades under a transferable warranty, and is the one system where we can stand behind both the material and the installation without qualifying it.
