Ferndale Siding Board & Batten Siding Built for Where Lummi Nation Sits
Lummi Nation occupies some of the most exposed ground in Whatcom County. Much of the community sits close to open water, which means homes here take a steadier beating from salt-laden air, wind-driven rain, and the long gray stretch of moss season than houses set back in Ferndale's more sheltered inland neighborhoods. Board and batten siding — with its bold vertical lines and deep shadow reveals — is a popular look out here, but it's also a siding style that punishes sloppy installation faster than lap siding does. Get the layering wrong and water finds the seams between boards. Get the material wrong and salt air and moisture cycles work into the substrate within a few seasons.
This page is specifically about board and batten for Lummi Nation properties: what the local climate actually does to this style of siding, what a correct installation looks like, and why we install it in one material only — James Hardie fiber cement.
What This Climate Does to Vertical Siding
Salt Air and Marine Exposure
Homes near Lummi Bay, Hale Passage, and the surrounding shoreline deal with airborne salt that inland Ferndale properties rarely see. Salt is hygroscopic — it pulls moisture out of the air and holds it against a wall surface. On wood-based sidings, that means slower drying, more swelling and shrinking, and faster breakdown of paint film and caulk. On uncoated fasteners and trim, it accelerates corrosion. Any board and batten system installed this close to the water needs a siding material and a fastener package that were built to tolerate that exposure, not just tolerate rain.
Driving Rain and Wind Load
Storms coming off the Strait of Georgia and the Salish Sea arrive with real wind behind them, and board and batten's vertical joints are a natural place for wind-driven rain to get pushed sideways instead of running straight down. A batten that isn't fastened into solid framing, or a board gap that's too tight or too loose, becomes a place for water to be forced past the surface rather than shed off it.
Moss, Shade, and Slow-Drying Walls
Whatcom County's moss season runs long, and the tree cover and marine humidity around Lummi Nation keep north- and west-facing walls damp for extended stretches. Board and batten's deep vertical reveals create more shadow line and more surface area that stays out of direct sun, which is exactly the condition moss and mildew need. A siding material that doesn't absorb and hold moisture in that environment lasts dramatically longer than one that does.
What a Correct Board & Batten Installation Actually Involves
Spacing and Layout
Board and batten isn't just boards nailed to a wall with strips of trim over the seams. Proper layout accounts for consistent batten spacing, correct board width for the wall's proportions, and attention to how courses land around windows, doors, and corners so nothing gets cut down to an awkward sliver. Rushed layout is one of the most common reasons this style looks off on a finished home.
Drainage Plane and Rainscreen
Behind the boards, there has to be a functioning water-resistive barrier and, ideally, a rainscreen gap that lets any moisture that does get past the surface drain and dry out instead of sitting against the sheathing. In a marine climate like this one, skipping the rainscreen is one of the more expensive shortcuts a crew can take — the failure doesn't show up on day one, it shows up two or three winters later as rot behind the siding.
Fastening and Flashing
Every board and batten needs to be fastened into framing or solid blocking, not just into sheathing, and every penetration — vents, light fixtures, hose bibs — needs proper flashing integrated with the water-resistive barrier before the siding goes on. Near salt air, fastener corrosion resistance matters more than it does inland; we use fasteners rated for the exposure, not whatever is cheapest.
Why We Install Only James Hardie for This Style
Board and batten shows up in a few different materials, and we've made a deliberate call to install exactly one: James Hardie fiber cement, in either HardiePanel vertical siding or the Artisan batten profile. Fiber cement doesn't absorb water the way wood-based products do, it won't swell or cup with the seasonal humidity swings this area sees, and it's non-combustible — a real consideration with the dry-summer wildfire smoke seasons Washington has had in recent years. Hardie's ColorPlus factory finish is baked on and warranted against fading and peeling, which matters on a style where a huge share of the wall is exposed, painted surface. Hardie also engineers its product lines by climate zone (its HZ5 line is built for the wetter, harsher weather typical of the Pacific Northwest), and it backs the material with a strong, transferable limited warranty when it's installed to spec.
We don't install LP SmartSide, vinyl board and batten, Cemplank, Allura, or primed wood battens. That's not because those products have no merit — it's because we've standardized our crews, our fastening details, and our warranty conversations around one system we trust completely in this exposure, and mixing materials makes quality control harder to guarantee.
Comparing Board & Batten Materials in a Marine Climate
| Material | Moisture Behavior | Salt Air Durability | Maintenance | Typical Warranty |
|---|---|---|---|---|
| James Hardie fiber cement | Doesn't swell, cup, or rot; engineered moisture resistance | Strong — cement-based, not organic | Repaint on a long cycle; occasional wash | Long transferable limited warranty (30-yr class on siding) |
| Engineered wood (e.g. LP SmartSide) | Treated but wood-based; vulnerable if coating fails | Moderate — edge and cut-end exposure is a risk | Caulk and coating upkeep, watch cut edges | Shorter, often prorated |
| Vinyl board and batten | Won't rot but can warp/distort with heat and cold cycling | Fair — fasteners and trim more exposed | Low, but limited repaint options | Varies widely by manufacturer |
| Solid wood / primed spruce | Absorbs and releases moisture readily; prone to cupping | Weaker without diligent upkeep | High — frequent recoating and caulk checks | Typically none from the material itself |
Our Process for a Lummi Nation Board & Batten Project
Assessment and Exposure Read
Every estimate starts with a look at how exposed the specific walls are — proximity to open water, shade and tree cover, prevailing wind direction, and the condition of whatever siding is there now. A wall facing the water gets treated differently in the detailing than a sheltered side wall, even on the same house.
Tear-Off and Substrate Check
We remove the old siding and inspect the sheathing underneath for soft spots or hidden rot before anything new goes up. Covering a compromised wall with new siding just hides the problem; we address what we find before moving forward.
Water-Resistive Barrier and Flashing
A new WRB goes on correctly lapped, with flashing integrated at every window, door, and penetration, and a rainscreen gap where the wall assembly calls for one.
Hardie Installation
Boards and battens go up per James Hardie's installation instructions — correct fastener spacing and embedment, correct clearance at grade and roof lines, and factory-finished ColorPlus material handled to keep that finish intact.
Final Detailing and Walkthrough
Caulking, touch-up, and a walkthrough with the homeowner close out the job, along with the warranty paperwork registered in your name.
Ongoing Care Board & Batten Needs Out Here
- Rinse pollen, salt residue, and general grime off the siding once or twice a year with a garden hose or soft wash.
- Check caulking at butt joints, window trim, and corners annually — it's the first thing to fail and the cheapest thing to fix.
- Keep gutters clear so overflow doesn't run down the wall face and feed moss growth on shaded sides.
- Trim back vegetation and tree limbs that keep a wall in shade and slow to dry.
- Watch north- and west-facing walls for early moss or algae growth and address it before it spreads.
- Have any impact damage or loose battens repaired promptly rather than left through a wet season.
Why Local Experience on Lummi Nation Specifically Matters
Lummi Nation is sovereign tribal land, and depending on where a property sits, permitting and inspection can run through Lummi Nation's own planning and building process rather than through Whatcom County — that's a detail a contractor who's never worked out here can easily miss or get wrong, which costs time on the front end of a project. Beyond paperwork, a crew that's actually done siding jobs in this community already understands how close-in the water exposure runs, which walls take the worst of the weather, and how the moss and shade patterns play out across the seasons. That's the difference between a board and batten installation that's built to spec on paper and one that's actually built for this specific ground.
What This Typically Costs
Board and batten pricing depends on wall square footage, how much tear-off and sheathing repair is needed, trim complexity around windows and corners, and the color and profile chosen from Hardie's lineup. We won't quote a number without seeing the walls, but we're always upfront about what's driving the price on your specific home, and we'll tell you plainly if a full re-side isn't necessary yet.
