Why Board & Batten Keeps Showing Up on Whatcom County Homes
Board and batten has been a Pacific Northwest farmhouse and coastal staple for a long time, and it's having a real moment again in Ferndale and up and down the Whatcom County waterfront. The look is simple: wide vertical panels with narrow strips (battens) covering the seams. It reads clean on a modern build and just as comfortable on a century farmhouse. But the reason we bring it up on an educational page instead of just a gallery page is that board and batten lives or dies on the material underneath the look, and the material choice matters more here than in a drier climate.
Ferndale sits close enough to Bellingham Bay and the Strait of Georgia that homes take on real salt air exposure, on top of the driving rain that comes sideways off Pacific storms most of the winter, on top of a moss season that can run eight or nine months on north-facing walls under tree cover. Vertical board and batten has more seams and more edge exposure per square foot than lap siding, which means the product behind that look needs to actually handle water, not just look good in a photo.

What Board and Batten Actually Is, Installed Correctly
Board and batten is a rainscreen-style vertical siding pattern: broad panels (commonly 12", 16", or 18" wide with James Hardie's panel products, or built up from individual boards) set with a gap between them, then a narrower batten strip fastened over each seam. Done right, it's not just a design choice — it's a drainage system. The seams need a plane behind them for water to run down and out, fasteners need to land in framing at the correct spacing, and the bottom of every panel needs a way to shed water instead of wicking it up.
Where Installations Go Wrong
Most board and batten failures we get called out to inspect aren't material failures — they're installation shortcuts. Common issues:
- Battens face-nailed directly through both boards without proper fastener spacing, creating stress points that split panels during freeze-thaw or moisture cycling
- No rainscreen gap or drainage plane behind the panels, so any water that gets past the seams has nowhere to go but into the sheathing
- Panels butted tight to grade or a hard surface with no clearance, wicking ground moisture straight up into the bottom courses
- Caulk used as the primary water seal instead of proper flashing and lap details — caulk is maintenance, not waterproofing
- Butt joints between panel lengths left unflashed or improperly sealed, which is exactly where we see rot start on older installs
None of that is unique to one brand of siding. It's a statement about installation discipline. But it's also why the material underneath the pattern matters — some products are far less forgiving of these mistakes than others, and some hold up to correction and re-caulking over the decades better than others.
Why We Install James Hardie for This Application
We install James Hardie fiber cement exclusively, and board and batten is actually one of the clearest cases for why. Fiber cement is dimensionally stable — it doesn't expand and contract with moisture the way wood-based products do, which matters enormously on a pattern with this many seams and fastener points. A vertical batten strip that's fighting swelling and shrinking twice a season is a batten strip that eventually splits, cups, or pulls fasteners loose. James Hardie panels stay flat and hold a fastener the way they did on day one.
The other piece is the factory finish. James Hardie's ColorPlus finish is baked on in a controlled factory environment with a bond that's tested well beyond what field-applied paint achieves, and it comes with its own finish warranty separate from the product warranty. On a board and batten wall with dozens of exposed batten edges, that finish integrity at every cut and edge is what keeps the wall looking uniform ten and twenty years out, instead of showing a patchwork of touch-up paint at different ages.
HZ5 and the Ferndale Climate
James Hardie engineers its siding by climate zone, and the Pacific Northwest — including Whatcom County — falls under their HZ5 line, formulated for high-moisture, freeze-thaw regions. That's a meaningfully different product than what gets shipped to the desert Southwest. For a coastal town like Ferndale, where salt air accelerates corrosion on fasteners and trim and moss thrives on any wall that stays damp, a product engineered for exactly that moisture load is the right starting point, not an upsell.
Board and Batten Pattern Options with James Hardie
James Hardie offers a few paths to the board and batten look, and the right one depends on the home and the budget:
| Approach | How It Works | Best For |
|---|---|---|
| Vertical Siding panels with applied battens | Wide fiber cement panels installed vertically with separate batten strips fastened over the seams | Classic farmhouse look, full design control on batten spacing and width |
| Board and Batten panel product | Pre-formed panels that replicate the board-and-batten profile in a single engineered piece | Faster installs, consistent reveal lines, fewer field seams to manage |
| Mixed elevation approach | Board and batten on gables or accent walls, HardiePlank lap siding on the main field | Homes wanting the accent look without full vertical coverage costs |
All three use the same HZ5 substrate and ColorPlus finish system — the difference is purely aesthetic and labor, not durability.
The Trade-Offs of Board and Batten Worth Knowing Upfront
We'd rather tell you this before the estimate than after the invoice. Board and batten, even done well, costs more than horizontal lap siding on the same wall — more seams, more trim pieces, more cut edges to seal, and generally more labor hours per square foot. It's also less forgiving of a rough wall plane, since vertical lines show waviness that horizontal lines tend to hide. And any vertical pattern needs a properly designed rainscreen assembly behind it, which is a real cost line, not an optional add.
None of that means skip it. It means go in knowing the pattern is a premium look with a premium installation requirement, and the material you put behind it should match that investment rather than undercut it.
What a Correct Installation Should Include
Whether you hire us or someone else, this is the checklist we'd want a homeowner to hold any contractor to on a board and batten job:
- A drainage plane or rainscreen gap behind the panels, not panels fastened flat to the weather barrier
- Fasteners at manufacturer-specified spacing, landing in framing, not just sheathing
- Proper starter strips and clearance at the base course — minimum clearance from grade, decks, and roofing per James Hardie's published instructions
- Flashed and lapped horizontal joints where panel lengths meet, not caulk-only seams
- Batten strips fastened to allow for expansion, not pinned rigid at every point
- Factory-cut or properly sealed field cuts, since an unsealed cut edge is the single most common entry point for moisture on fiber cement
Maintenance Once It's Up
James Hardie board and batten is low-maintenance, not no-maintenance. In this climate we tell homeowners to plan on an annual walk-around: check caulking at trim and window returns, look at north-facing walls for moss or algae buildup and treat it before it holds moisture against the wall, and keep gutters clear so runoff isn't sheeting down the face of the siding. That's a fraction of the upkeep a wood-based board and batten system demands, but it's not zero.
What This Costs and What Drives the Price
Board and batten pricing varies with wall complexity, story height, trim detail, and which of the three approaches above you choose, so we won't quote a number here we can't stand behind sight unseen. What we can tell you is the main cost drivers, so an estimate makes sense when you get one: total seam and cut count, the amount of trim and corner detail, scaffolding or lift needs on multi-story walls, and whether existing siding needs to be stripped versus sided over on compliant sheathing.
