What Board and Batten Actually Is
Board and batten is one of the oldest siding profiles in the Pacific Northwest, and it never really went out of style — you'll see it on farmhouses along the Nooksack floodplain and on brand-new builds in Ferndale subdivisions alike. The look is simple: wide vertical boards (or panels) installed with narrower strips, called battens, covering the seams between them. That vertical rhythm reads as clean and modern on a new build, or rustic and traditional on an older farmhouse-style home, which is part of why it keeps getting specified by architects and homeowners in Whatcom County.
What most homeowners don't think about until later is that "board and batten" describes a look, not a material. You can build that same profile out of cedar, engineered wood, vinyl, or fiber cement — and the material you pick determines whether that clean vertical look survives a Ferndale winter for five years or thirty.

Why the Material Behind the Look Matters So Much
A board and batten wall has more seams and more exposed edges per square foot than lap siding does. Every batten strip creates two vertical joints, and every joint is a place where water can get behind the cladding if the material swells, shrinks, or the caulk fails. In a climate like ours — salt-laden marine air off the Strait of Georgia, long stretches of driving rain, and a moss season that can run from October clear into May — those joints get tested constantly.
This is exactly why we install board and batten exclusively in James Hardie fiber cement. It's not brand loyalty for its own sake — it's that the material's dimensional stability and moisture resistance matter more on this profile than on almost any other siding style we install.
The Core Problem With Other Materials in This Profile
- Cedar boards and battens move with humidity — swelling wet, shrinking dry — which opens hairline gaps at the battens over time and invites moisture and, eventually, rot at the base and around penetrations.
- LP SmartSide is an engineered wood product with a resin-treated strand core; it holds paint well when new, but it's still wood-based, meaning edge and cut-end sealing has to be perfect and stays that way for the life of the siding, or moisture finds a way in at the seams a board and batten profile is full of.
- Vinyl vertical panel systems that mimic board and batten look the part from the street but are thin, flexible, and expand and contract a lot with temperature — on a profile with this many joints, that movement shows.
James Hardie's Board and Batten Systems
Hardie builds board and batten a couple of different ways, and which one fits a given home comes down to budget, look, and the home's architecture:
HardiePanel Vertical Siding with Batten Strips
This is the classic approach: full fiber cement panels installed vertically, with separate Hardie trim battens fastened over the seams. It gives the most authentic deep-shadow board and batten look and is the most common system we install in Ferndale.
Hardie Artisan Vertical Siding
Hardie's higher-end Artisan line has a more refined, tighter-grain finish for homeowners who want a premium look, often paired with Hardie Trim battens for a crisper shadow line. It costs more per square foot but reads as a step up in finish quality, particularly on entries and street-facing elevations.
HZ5 vs HZ10 Engineering
Hardie engineers its products by climate zone — HZ5 for most of the continental U.S., HZ10 for the harshest coastal and freeze-thaw exposures. Whatcom County sits in a zone where the standard HZ5 formulation is what Hardie specifies and what we install; it's engineered for wet, temperate climates like ours rather than desert heat or deep-freeze regions.
Installation Is Where Board and Batten Succeeds or Fails
More than any other siding style, board and batten lives or dies on installation detail. A crew that treats it like lap siding with vertical boards will get callbacks. The details that actually matter:
Drainage Plane and Rain Screen
Behind every board and batten wall we install, there's a weather-resistive barrier and, on most projects, a furring or rain-screen gap that lets any incidental moisture drain and the wall assembly dry out. This matters more on vertical siding than horizontal lap because water runs straight down the face and along every batten joint rather than shedding off overlapping courses.
Fastening Pattern
Battens need to be fastened into structural framing or properly blocked sheathing, not just into the panel below — a batten that's only holding onto the panel face will work loose over a few Whatcom County winters of wind-driven rain and freeze-thaw cycling.
Joint and Butt Seams
Where panels meet end to end, Hardie's installation instructions call for specific gapping and flashing details. Skipping these is the single most common cause of vertical siding failure we see when we're called out to diagnose problems on homes built by other crews.
Caulk Is a Backup, Not a Strategy
A board and batten wall that depends on caulk to stay watertight will fail the day that caulk does. Correct flashing and drainage detailing should keep the wall dry even if the sealant eventually cracks — which it will, on any home, eventually.
Comparing Board and Batten Materials
| Material | Moisture Behavior | Maintenance | Typical Lifespan | Factory Finish Option |
|---|---|---|---|---|
| James Hardie Fiber Cement | Dimensionally stable, doesn't swell or rot | Occasional wash; no repainting with ColorPlus | 30+ years to warranty term | ColorPlus baked-on finish |
| Cedar | Absorbs moisture, swells/shrinks seasonally | Re-stain or repaint every 3-7 years | 15-25 years with upkeep | Site-applied stain only |
| LP SmartSide | Engineered wood core; edge sealing critical | Repaint every 7-10 years, inspect seams | 20-30 years if maintained | Factory primed, field painted |
| Vinyl Vertical Panel | Doesn't rot, but expands/contracts with heat | Low; occasional wash | 20-25 years | Color molded through, fades over time |
Color, Finish, and the ColorPlus Difference
Every board and batten job we install uses Hardie's ColorPlus finish where the color option allows it — the color is baked on at the factory under controlled conditions, rather than sprayed or rolled on-site. On a profile with this many edges and joints, a factory finish gives more even coverage and a stronger bond than field-applied paint, which is one more reason board and batten specifically benefits from Hardie over a paint-it-yourself product. Hardie backs ColorPlus with its own finish warranty, separate from and in addition to the substrate warranty on the fiber cement itself.
What Board and Batten Actually Costs
Board and batten runs somewhat higher per square foot than standard lap siding, mainly because of the extra material (the battens themselves) and the additional labor to fasten and align them correctly. Exact numbers depend heavily on the home's elevation complexity, trim detail, and whether it's a full re-side or a feature-wall accent, so we'd rather walk a specific home than quote a number that doesn't apply to it. Broadly, expect it to run above a straight lap siding install and below full stone or true wood-shingle work.
| Cost Factor | Why It Matters |
|---|---|
| Panel vs. batten labor | Two-step install (panel, then batten) takes more crew time than single-pass lap siding |
| Trim and corner detail | Board and batten shows trim quality more than most profiles — corners and window returns take extra care |
| Full re-side vs. accent wall | Many homeowners use board and batten as a gable or entry accent rather than whole-house, which changes total cost significantly |
| ColorPlus vs. field paint | Factory finish costs more upfront but removes a repaint cycle |
Ferndale and Whatcom County Climate Considerations
Ferndale sits close enough to the Strait of Georgia that salt-laden air is a real factor on siding, especially on homes with western or northern exposure that catch the weather coming off the water. Combine that with Whatcom County's long stretch of driving rain each fall and winter, and a moss season that can linger from early fall into late spring on shaded north-facing walls, and you've got a climate that's genuinely tough on cladding — not extreme heat or extreme cold, but relentless dampness. Board and batten's extra joints make it less forgiving than lap siding in exactly this kind of climate if the material or installation isn't right, which is a big part of why we don't cut corners on either.
Maintenance Checklist for Board and Batten Homes
- Rinse the siding annually, focusing on north-facing walls where moss and algae take hold first
- Walk the batten lines each fall and look for caulk that's cracked, shrunk, or pulled away from the joint
- Check the base of the wall near grade for splash-back staining or standing debris that holds moisture against the siding
- Inspect flashing above windows and doors where board and batten meets trim
- Keep gutters clear so overflow doesn't run down the face of the wall between battens
- Trim back vegetation and tree cover that keeps shaded walls damp longer after rain
