How is board and batten siding actually installed, and what makes it different from standard lap siding?

Board and batten uses vertical panels or boards with narrower strips (battens) covering the seams, rather than horizontal overlapping courses. It requires a drainage gap behind the siding, careful flashing at every seam, and a specific fastening pattern, because it has more vertical joints per square foot where water can intrude if the details aren't right.

What questions should I ask a contractor before hiring them for a board and batten project?

Ask what siding material and brand they install and why, whether they include a rainscreen/drainage gap in their installation, how they handle flashing at windows and doors, and whether their workmanship is backed by a written warranty in addition to the manufacturer's product warranty. A contractor who can answer these clearly and specifically is worth more than one offering the lowest bid.

Why does this company only install James Hardie instead of offering multiple siding brands?

We standardized on James Hardie because it's dimensionally stable, non-combustible, and factory-finished with a warrantied ColorPlus coating, which holds up better to our region's moisture and salt air than wood, vinyl, or engineered wood alternatives. Offering one product we trust fully seemed more honest than offering several we'd have reservations about.

Does James Hardie make a specific product for board and batten, or is it a custom detail?

James Hardie produces vertical panel siding that's installed with battens to create the classic board and batten look, along with factory-primed trim boards for the battens themselves. The reveal width and batten spacing are chosen during design and installed according to Hardie's published fastening and flashing specifications.

Does Bellingham's climate call for anything different than a typical Pacific Northwest install?

Whatcom County combines wind-driven rain, airborne salt from the Sound, and a long moss season, which together put more stress on vertical siding joints than a drier or more inland climate would. That combination is why drainage details, corrosion-resistant fasteners, and sealed cut edges matter more here than in many other parts of the country.

Expert Board & Batten Siding for Cordata Homes

Board & Batten in Cordata: A Style That Has to Earn Its Keep

Board and batten has become one of the most requested looks for homes in and around Bellingham, and it's easy to see why — the strong vertical lines read as modern on a new build and as classic farmhouse on an older one. But in Whatcom County, board and batten isn't just a design choice. Every vertical joint, every batten seam, and every reveal is a place where our climate gets a chance to do damage if the material and the installation aren't right for it. Cordata homes sit under the same weather pattern as the rest of Bellingham: salt-laden air moving in off the water, long stretches of driving, wind-pushed rain, and a moss season that can run from early fall through late spring. A board and batten system that looks great going up has to be able to shed that weather for decades, not just survive the first few winters.

What Bellingham's Weather Actually Does to Vertical Siding

Driving Rain and Wind-Driven Moisture

Board and batten relies on overlapping vertical members to shed water down the face of the wall. That works well in calm rain. It works much less well when wind is pushing rain sideways into every seam, which is a regular occurrence in this part of Washington. Without the right water-resistive barrier, flashing details, and drainage plane behind the siding, wind-driven rain finds its way behind the battens and into the sheathing — and it can sit there for months before anyone notices a problem.

Salt Air and Corrosion

Bellingham's proximity to Puget Sound means homes here deal with airborne salt that inland Washington properties never see. Salt air accelerates corrosion on exposed fasteners, staples, and lower-grade metal flashing. Over years, corroding fasteners loosen, siding boards shift, and small gaps open at exactly the joints that are supposed to be sealed.

Moss, Mildew, and Shaded Lots

Whatcom County's moss season is long, and many residential lots in this part of Bellingham carry enough tree cover to keep north- and west-facing walls damp for days after a storm passes. Moss and mildew don't just look bad on siding — they hold moisture against the surface, and on the wrong material that moisture eventually works its way into the substrate through hairline cracks, cupped boards, or failed caulk joints.

Why We Only Install Board & Batten in James Hardie Fiber Cement

We get asked regularly why we don't offer board and batten in cedar, vinyl, or engineered wood like LP SmartSide. The honest answer is that we've seen how each of those materials performs over a decade or two in this exact climate, and none of them hold up to Bellingham's combination of moisture, salt air, and moss the way fiber cement does.

Solid wood board and batten looks beautiful new, but it moves with humidity — swelling, shrinking, and eventually cupping or splitting at the battens. That movement opens gaps at the exact joints that need to stay tight, and it commits an owner to repainting on a recurring cycle.
Vinyl board and batten is low-maintenance in the sense that it doesn't rot, but it's a thin, flexible material trying to hold a crisp architectural line. Panels can bow, fade unevenly in UV exposure, and the vertical battens are often hollow trim pieces rather than structural boards, which limits how convincing the look is up close.
Engineered wood products like LP SmartSide perform reasonably when every cut edge is factory-sealed or field-treated exactly to spec, but that's a big "if" on a job with dozens of vertical joints. Any cut edge that isn't properly sealed becomes a wicking point, and in a wet climate like ours, that's where failure starts.

James Hardie fiber cement doesn't have those failure modes. It's dimensionally stable, so the battens stay flat and the reveals stay consistent instead of opening up as the material ages. It's non-combustible. And it comes from the factory with a ColorPlus finish baked on and warrantied against fading and peeling, rather than relying on job-site paint that has to be redone every several years. James Hardie also engineers its formulations by climate zone, which matters in a region like ours where humidity and moisture exposure are the dominant stress, not freeze-thaw cycling. That's the whole reason we standardized on one manufacturer instead of offering a menu of materials — we'd rather install one system correctly than install several systems knowing some of them won't hold up here.

What a Correct Board & Batten Installation Involves

Board and batten is less forgiving of shortcuts than lap siding, simply because it has more vertical seams per square foot of wall. A correct installation in this climate includes:

A drainage gap (rainscreen or vertical furring) between the siding and the weather-resistive barrier, so any moisture that does get past the surface can drain and dry instead of sitting against the sheathing
Properly lapped and sealed weather-resistive barrier and flashing at every window head, door head, and penetration before the first panel goes up
Panel and batten fastening that follows James Hardie's published fastening schedule for spacing, edge distance, and fastener type — not a generic siding pattern
Corrosion-resistant fasteners appropriate for a coastal-influenced climate, given what salt air does to lower-grade hardware over time
Correct batten spacing and reveal so the wall reads evenly and water is shed to the next course down, not trapped at a joint
Factory-primed or ColorPlus-finished cut edges sealed in the field wherever a cut exposes raw material
A starter strip and base flashing detail that keeps the bottom course off grade and away from splash-back moisture

Skipping any one of these doesn't usually cause a visible problem in year one. It shows up in year five or eight, as staining, soft spots, or boards that have started to separate at the seams — which is a far more expensive fix than doing it right the first time.

Comparing Board & Batten Materials for a Bellingham Home

Material	Moisture Behavior in This Climate	Maintenance Over 15+ Years	Typical Warranty Support
James Hardie fiber cement	Dimensionally stable; resists moisture-driven warping and cupping	Occasional rinse; ColorPlus finish resists fading/peeling	Strong transferable product and finish warranty
Solid wood (cedar)	Absorbs and releases moisture with weather swings; prone to cupping	Recurring repainting or restaining; caulk joint upkeep	Limited, largely dependent on finish applied
Vinyl board and batten	Doesn't rot, but can bow or gap; not a rigid architectural material	Low, but limited repair options if damaged or faded	Prorated, often weaker over time
Engineered wood (LP SmartSide-type)	Performs only if every cut edge stays fully sealed	Field sealing and inspection of joints required	Can be voided by improper field sealing

Our Process for Cordata Homeowners

On-site assessment. We look at the existing wall assembly, check for signs of moisture already behind the current siding, and evaluate exposure — how much wind-driven rain and shade a particular elevation actually gets.
Design and reveal selection. Board and batten reveal width and color changes the whole feel of a home. We walk through James Hardie's board and batten and vertical panel options and ColorPlus palette so the final look matches the house, not just a catalog photo.
Tear-off and substrate check. Once old siding comes off, we inspect and repair sheathing before anything new goes up — installing over a compromised substrate just locks the problem in.
Installation to manufacturer spec. Rainscreen, flashing, fastening schedule, and sealed cut edges, done in the order that actually keeps water out rather than the order that's fastest.
Trim, finish, and cleanup. Corner and trim details finished, site cleaned of debris and fasteners, and a full walkthrough before we call the job done.
Warranty paperwork. We register the installation so the homeowner has both the manufacturer's product warranty and our own workmanship coverage on file.

Why a Crew That Already Works in Cordata Matters

Cordata is a growing residential part of north Bellingham, with a mix of home ages and construction styles rather than one uniform building era. That matters on a siding job, because the right approach for a newer home with modern house wrap is not automatically the right approach for an older wall assembly. A crew that already works jobs throughout Bellingham and Whatcom County has a working sense of how local permitting is handled, what inspectors want to see on a re-side, and how exposure varies from a more open, wind-exposed lot to a sheltered, tree-covered one just a few streets over. That local familiarity doesn't replace doing the assessment on your specific house — but it does mean fewer surprises and fewer change orders once the old siding comes off.

Keeping Board & Batten Looking Right After Installation

Rinse the siding once or twice a year to clear pollen, salt residue, and organic buildup before it can support moss growth
Keep gutters and downspouts clear so overflow doesn't sheet down the wall and concentrate moisture at specific batten runs
Trim back vegetation and tree limbs that keep a wall shaded and damp longer than the rest of the house
Do a yearly visual check of caulking at trim, window, and door junctions, and have any cracked sealant redone before winter
Touch up any nicks or scrapes with a matching ColorPlus touch-up product rather than a generic exterior paint
