What exactly is board and batten siding?

It's a siding profile made of wide vertical panels or boards with narrower strips, called battens, covering the seams between them. It creates a clean, vertical shadow-line look that's common on farmhouse and modern exteriors alike, and it dates back to a practical way of covering joints on wood-clad buildings long before manufactured materials existed.

How do I know a contractor is actually qualified to install board and batten, not just siding in general?

Ask them to walk you through the rainscreen or drainage gap plan, the fastener spacing, and how they'll flash windows and trim before any siding goes up — if they can't explain those details without prompting, they likely haven't installed much of this specific profile. Manufacturer certification and a written workmanship warranty are also good signs they're set up to do it correctly.

Why doesn't your company install vinyl or wood board and batten?

We standardized on James Hardie fiber cement because it holds up to this region's rain and salt air without the repainting cycle wood requires or the seam and fade issues we see with vinyl over time. Both products have their place, but for the moisture load and longevity homeowners here want, fiber cement is what we're willing to put our name behind.

What's the difference between HardiePanel vertical siding and traditional board and batten boards?

HardiePanel is a large fiber cement sheet installed vertically with HardieTrim battens covering the seams, giving fewer joints to seal and a faster, tighter installation. True board and batten uses narrower individual boards with a batten over every joint, which gives a more traditional, closer-spaced look but has more seams to detail correctly. Both use the same climate-engineered fiber cement material.

Does Ferndale's location change anything about how the siding should be installed compared to homes right on the water?

The core assembly — water-resistive barrier, rainscreen gap, correct flashing, corrosion-resistant fasteners — doesn't change, because Whatcom County's rain and airborne salt affect the whole area, not just waterfront lots. What can shift is exposure severity on a given wall depending on prevailing wind and how sheltered the site is, which is something we assess on each property rather than assuming from the address alone.

Ferndale Board & Batten Siding for Whatcom County Homes

Board & Batten Siding, Built for Ferndale's Weather

Board and batten has been a familiar look on Whatcom County homes for a long time, and it's still one of the most requested siding profiles in Ferndale today. The vertical lines suit farmhouses, newer construction, and everything in between, and it gives a home a cleaner, more architectural look than a plain lap profile. But board and batten isn't just a style choice. It's a system with more seams and more fastening points than horizontal siding, and in a climate that mixes salt-tinged air, long stretches of driving rain, and a moss season that can run most of the year, those extra seams matter. Get the details right and board and batten will outlast the house. Get them wrong and you're looking at trapped moisture, streaking, and premature repairs within a few years.

This page is about that one job, done right, for homes in the Ferndale area specifically — not a generic overview of siding styles.

What Local Weather Actually Does to This Profile

Salt Air and Fasteners

Whatcom County's proximity to Puget Sound and the Strait of Georgia means airborne salt is a real factor for exterior materials, even for homes that aren't directly on the water. Salt-laden air accelerates corrosion in fasteners, flashing, and any exposed metal trim. Board and batten has more nail penetrations per square foot than lap siding because the battens themselves are fastened through to the framing or furring. If those fasteners aren't rated for the exposure, you get rust streaking down the face of the siding long before the siding itself has a problem.

Driving Rain and Seam Design

Wind-driven rain doesn't fall straight down — it gets pushed sideways and upward under laps, around corners, and into any gap that isn't properly lapped or sealed. Board and batten relies on the batten covering the joint between two panels or boards to shed water outward. If the batten spacing, panel gap, or fastener pattern is off from manufacturer spec, water can work its way behind the batten instead of running over it, and once it's behind the cladding it needs somewhere to go.

Moss and Shaded Elevations

Board and batten's vertical grooves and shadow lines actually shed surface water a bit better than flat lap siding, but the north and west-facing walls that stay shaded and damp for long stretches of the year will still grow moss and mildew if the surface finish can't stand up to it. This is less about the profile and more about the finish and the ventilation behind it, both of which are choices made at installation.

The Part Homeowners Rarely See: The Rainscreen Gap

The single biggest factor in how long board and batten siding lasts in this climate isn't the siding material at all — it's whether there's a drainage gap between the siding and the wall behind it. A rainscreen assembly uses vertical furring strips over the water-resistive barrier, creating a continuous air and drainage space behind the cladding. Any moisture that does get past the battens can drain and dry out instead of sitting against the sheathing.

Board and batten without a rainscreen gap can still perform acceptably in a dry climate. In a wet coastal county with long moss seasons, skipping it is one of the most common reasons board and batten siding fails early — not from a bad product, but from a shortcut on the assembly behind it.

Water-resistive barrier installed and lapped correctly, shingle-style, over all sheathing seams
Vertical furring strips (or a manufactured drainage mat) creating a continuous drainage gap
Flashing at every window, door, and horizontal trim transition, integrated with the barrier — not just caulked over the top
Fasteners long enough to reach solid framing through the furring space, not just tacked to the furring strip itself
Corrosion-resistant fastener coating appropriate for coastal exposure

Why We Only Install James Hardie for This Profile

Board and batten has traditionally been done in solid wood, and it can look great new. The problem in this climate is what happens over time: wood boards absorb moisture at the end grain and at every batten fastener point, and in a county that sees rain across most months of the year, that means swelling, cupping, and eventually rot — usually starting at the bottom courses and around any penetration. Repainting raw wood board and batten on a normal cycle is part of owning it, and skipping a cycle in this climate catches up fast.

James Hardie's fiber cement board and batten system is built from cement, sand, and cellulose fiber, so it doesn't absorb water the way wood does, doesn't support moss and mildew growth on the surface itself, and won't warp or cup at the fasteners. It's also non-combustible, which matters given the dry-season wildfire smoke and ember exposure that has become a bigger part of Pacific Northwest summers even in wetter counties. Hardie's factory-applied ColorPlus finish is baked on under controlled conditions, so the color holds up to UV and salt air exposure far better than a field-applied paint job on raw wood, and touch-up matching is simpler because it's a manufactured, consistent finish rather than a hand-mixed batch.

Hardie also engineers its siding formulations by climate zone rather than using one blend everywhere. Homes in wetter coastal counties like Whatcom generally call for the moisture-focused formulation rather than the version engineered primarily around freeze-thaw cycling. Specifying the right version for the exposure is part of doing the job correctly, not an upsell.

HardiePanel Vertical Siding vs. True Board and Batten Boards

There are two ways to get the board and batten look in fiber cement: large HardiePanel vertical sheets with HardieTrim battens fastened over the seams (the most common approach, fewer seams, faster to seal correctly), or individual narrower boards installed with battens over each joint for a more traditional, tighter-spaced look. Both use the same fiber cement material and the same climate-engineered finish — the choice is mostly aesthetic and budget-driven, and we'll walk through which fits a given home during the estimate.

Comparing Your Board & Batten Options

Factor	James Hardie Fiber Cement	Solid Wood	Vinyl Vertical Panel
Moisture & rot resistance	Does not absorb water; won't rot or cup	Absorbs moisture at joints and end grain; prone to rot without upkeep	Won't rot, but seams and edges can trap moisture behind panels
Maintenance	Occasional wash; no repainting on factory finish	Repainting/staining on a regular cycle, more often near salt air	Low maintenance but can crack or fade, especially in UV and cold
Fire resistance	Non-combustible	Combustible	Combustible, can warp near heat sources
Appearance over time	Holds factory color and crisp lines for years	Authentic look new, but shows weathering and touch-up patches	Can look plasticky up close; fades unevenly
Typical lifespan when installed to spec	Multiple decades	Highly dependent on maintenance discipline	Decades, but seams and fasteners are the weak point

Our Installation Process for This Job

Assessment: We inspect the existing wall assembly, check for any hidden moisture damage behind current siding, and confirm the substrate is sound before anything new goes on.
Water management first: Water-resistive barrier goes on and is lapped correctly at every seam, with flashing integrated at windows, doors, and any wall penetration before a single piece of siding is measured.
Furring and drainage gap: Vertical furring strips are installed to create the rainscreen gap, sized to manufacturer spec so the battens have solid backing wherever they're fastened.
Panel or board installation: HardiePanel or individual boards are set with the correct gap and fastener pattern specified for the climate zone and exposure.
Battens: Battens are fastened directly into framing through the furring space, covering each seam fully, with corrosion-resistant fasteners throughout.
Trim, corners, and sealant: Corner boards and trim are finished, and sealant is applied only where the manufacturer calls for it — over-caulking board and batten can trap moisture instead of shedding it.
Final inspection and cleanup: We walk the job with the homeowner before calling it done.

What to Check Before You Hire Anyone for This Job

Do they mention a rainscreen or drainage gap as part of the plan, without you having to ask?
Are they specifying corrosion-resistant fasteners appropriate for coastal air, not just whatever's in the truck?
Do they carry manufacturer certification for the fiber cement system they're installing?
Is the warranty in writing, and does it cover workmanship separately from the manufacturer's material warranty?
Can they explain why they're recommending board and batten specifically for your home's exposure, not just because you asked for it?
Do they have a plan for existing moisture damage if it turns up once old siding comes off?

Why a Crew That Already Works Ferndale Matters

Board and batten done wrong doesn't usually fail in year one — it fails in year five or six, quietly, behind the wall, which is exactly why the installation details matter more than the material choice. A crew that regularly works Whatcom County homes has already seen what this climate does to a wall assembly that skipped the rainscreen gap, or used the wrong fastener, or under-flashed a window. That's knowledge you can't get from a spec sheet, and it's the difference between board and batten siding that looks right for a season and siding that's still doing its job in twenty years. It also means a straightforward path back to us if a warranty question ever comes up, instead of chasing down a contractor who only worked in the area for one job.
