Ferndale Board & Batten in Lynden: A Style That Has to Earn Its Keep
Board and batten shows up on a lot of homes around Lynden — on farmhouses, on newer builds going for that clean vertical-line look, and on additions where a homeowner wants a barn-style accent wall or a full facade with strong shadow lines. It's a good-looking profile, and in a rural, agricultural community like Lynden it fits the surroundings in a way that a lot of siding styles don't.
But board and batten isn't just a look. It's a drainage system. The vertical boards and the battens covering the seams between them have to move water down and off the wall, not hold it against the sheathing. In Whatcom County, where the siding on any given wall might see driving rain sideways for days at a stretch and salt-laden air rolling in off the coast, that detail is the difference between siding that lasts and siding that fails quietly behind its own good looks.
What This Climate Actually Does to Vertical Siding
Salt air
Ferndale and the surrounding Whatcom County towns, Lynden included, sit close enough to salt water that airborne salt is a real factor on fasteners, trim, and any metal flashing components. Salt accelerates corrosion on the wrong hardware, and corroded fasteners in a board and batten system are a slow leak waiting to happen — you don't see it until the board starts to separate or a rust streak shows up.
Driving rain
Wind-driven rain doesn't just fall on a wall, it gets pushed into it. Vertical board and batten has more seams per square foot than lap siding, and every one of those seams — at the top of each board, behind each batten, at every window and corner — is a place water will test if it isn't detailed correctly.
Long moss season
Whatcom County's wet season runs long, and shaded north and west walls stay damp for extended stretches. Moss and algae need that sustained moisture to take hold, and once established they hold even more water against the siding surface. A material and finish that resists that buildup, and a design that lets the wall dry out between rain events, both matter more here than in a drier climate.
What a Correct Board & Batten Job Actually Involves
The visible boards and battens are the easy part to judge. The parts that determine whether the job lasts are underneath:
- A drainage plane (weather-resistive barrier) installed and lapped correctly, with all penetrations sealed
- A rainscreen gap or furring behind the panel so water that gets past the surface can drain and the wall can dry
- Corrosion-resistant fasteners sized and spaced to the manufacturer's specification, not just "close enough"
- Proper flashing at every window, door, and roofline intersection — these are the highest-failure points on any vertical siding job
- Correct starter strip and base detail so the bottom of the wall isn't wicking moisture up from grade or a deck ledger
- Batten fastening that doesn't just clamp the seam shut but allows the assembly to handle normal expansion and contraction
Skip any one of these and the siding can still look right for a year or two. The problems show up later, as soft spots, staining, or bowing boards — and by then the fix usually means opening up the wall.
Why We Install It in James Hardie Fiber Cement, Not Wood or Vinyl
Board and batten can be built out of a few different materials, and we get asked about most of them. We install James Hardie fiber cement exclusively, and for this specific style in this specific climate, the reasoning is pretty direct.
Fiber cement holds its shape
Wood board and batten looks great new, but real wood moves with moisture — it swells, shrinks, and eventually cups or splits, especially on the wetter faces of a house. That movement stresses the batten fasteners and opens gaps. Hardie's fiber cement panels are dimensionally stable across wet and dry cycles, which matters more on a vertical profile than almost any other siding style, because vertical seams are where movement shows up first.
The finish resists what this climate throws at it
Hardie's ColorPlus factory finish is baked on and warrantied against fading and cracking, and it holds up to sustained damp weather better than field-applied paint, which is what most wood board and batten depends on. Less repainting means less scaffolding, less cost, and less chance of a maintenance gap turning into a moisture problem.
It's engineered for the Pacific Northwest specifically
James Hardie makes climate-specific HZ product lines, and the HZ5 formulation is built for the wetter, milder conditions common to Western Washington. That's a material decision made for exactly the weather Lynden and Ferndale get, not a one-size-fits-all national spec.
Non-combustible
Fiber cement doesn't burn. That's a real, practical benefit independent of the local climate conversation, and it's part of why we standardized on Hardie across every siding style we install, board and batten included.
Where Board & Batten Installations Go Wrong
Most of the board and batten failures we get called out to inspect trace back to a handful of repeat mistakes:
- No rainscreen gap — panels fastened directly to the weather barrier with no way for incidental moisture to drain or the wall to dry
- Battens face-nailed through both boards and the substrate without accounting for movement, causing splitting or fastener popping
- Missing or undersized flashing at window heads, letting water track behind the panel at the most common trouble spot on the wall
- Boards run too close to grade or a hardscape surface, so the bottom edge sits in a permanent damp zone
- Butt joints and corners caulked instead of flashed, relying on sealant that will eventually fail as the sole line of defense
None of these show up on install day. They show up two, five, or ten years later, which is exactly why the installer's judgment on the parts you can't see matters more than the parts you can.
Our Process for Board & Batten Work in Lynden
We walk every job the same way, whether it's a full re-side or an accent section:
- Assessment — check the existing wall assembly, sheathing condition, and any signs of past moisture intrusion before quoting anything
- Moisture and drainage plan — confirm the weather barrier and rainscreen approach for the specific wall orientation, since a north-facing wall in Lynden's wet season needs the same rigor as a south-facing one exposed to driving rain
- Flashing detail first — windows, doors, and rooflines get flashed and inspected before a single board goes up
- Panel and batten installation — to James Hardie's fastening and spacing specification, not a generalized approach borrowed from lap siding
- Final walkthrough — we go over the finished wall with the homeowner and point out what to expect long-term, including how the ColorPlus finish will hold up and what routine maintenance actually looks like (usually very little)
Comparing Board & Batten Material Options
| Factor | James Hardie Fiber Cement | Wood | Vinyl Vertical Panel |
|---|---|---|---|
| Moisture stability | High — engineered for wet climates | Low — swells, shrinks, can cup | Moderate — doesn't rot but seams flex |
| Finish maintenance | Factory ColorPlus finish, long repaint interval | Repainting every few years is typical | Color molded in, but fades and chalks over time |
| Fire resistance | Non-combustible | Combustible | Melts/deforms under heat |
| Appearance over time | Holds crisp lines and shadow reveal | Can warp, showing wavy battens | Can oil-can or show seams in direct sun |
| Typical warranty structure | Long-term, transferable manufacturer warranty | Installer workmanship only, in most cases | Manufacturer warranty, often prorated |
This isn't a knock on wood or vinyl as products — each has a place. It's why, for the specific demands of a vertical, seam-heavy profile in a wet coastal climate, we've made fiber cement the only material we put on a wall.
Why It Matters That We Already Work This Area
A crew that installs siding across a lot of different climates tends to default to generic details. A crew that works Ferndale, Lynden, and the rest of Whatcom County regularly knows which walls take the worst of the driving rain, which orientations grow moss fastest, and where salt air does the most damage to hardware — and builds the flashing and fastening plan around that instead of a national average. That local pattern recognition is most valuable on a style like board and batten, where the seams and details carry more of the waterproofing burden than they do on standard lap siding.
