Board & Batten in Ferndale: A Style With a Job To Do
Board and batten shows up a lot on new builds and remodels around Ferndale, and it's easy to see why. The vertical lines read as clean, modern-farmhouse, or classic Pacific Northwest depending on the trim details and color, and it pairs well with the mix of ranch, craftsman, and newer construction you see through this part of Whatcom County. But board and batten isn't just a look. It's a siding profile with its own set of seams, fastening points, and drainage requirements, and in this climate those details decide whether the siding lasts twenty-plus years or starts failing at the joints in five.
This page is specifically about board and batten for homes in and around Ferndale, near Blaine — not a general overview of the style. The material choice, the install details, and the maintenance rhythm we recommend here are shaped by what this stretch of Whatcom County actually deals with every year: salt air, driving rain, and a long moss season that doesn't let up until well into spring.

What Ferndale's Climate Asks of Vertical Siding
Three things drive most of the siding problems we see on board and batten jobs in this area:
- Salt air. Homes closer to the water deal with airborne salt that accelerates corrosion on fasteners, flashing, and any metal trim. Board and batten has more exposed vertical seams than lap siding, so corrosion-resistant hardware isn't optional here — it's the difference between battens that stay tight and battens that start working loose.
- Driving rain. Wind-driven rain off the Strait pushes water sideways, not just down. Vertical board and batten channels water differently than horizontal lap siding, and if the drainage plane behind it isn't built correctly, that rain finds its way behind the boards instead of running off them.
- A long moss season. Whatcom County stays damp for a big part of the year, and moss and algae will colonize any siding surface that holds moisture or sits in constant shade. Board and batten's vertical grooves and batten shadow lines give moss more edges to grab onto than a flat panel does, which makes surface prep and finish quality matter more, not less.
None of this means board and batten is a bad choice for Ferndale. It means the material and the installation have to be matched to the conditions, and that's where a lot of siding jobs — done with the wrong product or rushed details — start showing problems early.
Why Material Choice Matters More on Vertical Siding
Board and batten depends on straight, stable boards and battens that stay flat and tight to the wall for decades. Wood species like primed spruce look right on day one, but they move with moisture, and that movement shows up fast on a vertical profile — cupping boards, gapping battens, paint that fails along the grain lines. Vinyl board and batten stays dimensionally stable but it's a thin, flexible material; in driving rain and salt air it can rattle, fade unevenly, and its butt joints are a constant maintenance point. LP SmartSide and other engineered wood products perform reasonably well when kept sealed and dry, but their long-term durability depends heavily on caulking and paint maintenance staying current — a schedule that's easy to fall behind on with Ferndale's wet winters.
We install James Hardie fiber cement exclusively, and board and batten is one of the styles where that decision pays off the most. Fiber cement doesn't expand and contract with humidity the way wood does, it doesn't flex or oil-can the way vinyl can, and it takes a factory-cured ColorPlus finish that isn't relying on field paint to hold up against salt air and UV. On a profile with this many vertical seams and shadow lines, starting with a dimensionally stable board is what keeps the whole system looking straight and tight over time.
How We Detail Board & Batten for This Climate
The board and batten look is simple. The assembly behind it isn't, and this is where most of the long-term performance is decided.
Drainage plane and rainscreen gap
Vertical siding needs a clear path for any water that gets behind it to drain out and dry. We install a weather-resistant barrier and furring strips to create a rainscreen gap behind the boards, so moisture that reaches the wall assembly can escape instead of sitting against the sheathing — a detail that matters even more here given how much rain this area sees over the course of a winter.
Flashing at every horizontal break
Window heads, door heads, and any horizontal trim need proper flashing that sheds water out and away from the wall, not just caulk. Caulk fails; flashing doesn't, as long as it's installed correctly the first time.
Fastening for coastal conditions
We use corrosion-resistant fasteners set to Hardie's spec, at the correct spacing and depth, so boards and battens stay fixed tight to the wall without split boards or fastener heads that eventually rust and streak the finish — a real risk with salt-laden air.
Gaps and sealant, used correctly
Board and batten needs small expansion gaps at trim and inside corners, sealed with a high-quality, paintable sealant rated for the exposure. We don't caulk every seam solid — a common shortcut that traps moisture instead of letting the assembly breathe and drain as designed.
Board & Batten Options in the Hardie Lineup
James Hardie offers a couple of ways to get the board and batten look, and the right one depends on the home and the desired reveal:
- HardiePanel with battens — vertical fiber cement panels installed with wood or fiber cement battens over the seams, giving a traditional board and batten shadow line.
- Artisan Vertical Siding — a premium, thicker panel product with deeper, more dimensional reveals for a higher-end board and batten appearance.
Both come pre-finished in Hardie's ColorPlus baked-on finish, which matters specifically for moss and mildew resistance — a factory finish resists staining and holds color more consistently than field-applied paint, which is one less maintenance headache during a wet Whatcom County winter.
Our Process for a Ferndale Board & Batten Project
| Step | What Happens |
|---|---|
| Site assessment | We check existing siding, sheathing, and any moisture damage before quoting — board and batten installed over a compromised wall just hides a bigger problem. |
| Tear-off and prep | Old siding comes off, sheathing is inspected and repaired as needed, and the weather-resistant barrier is installed or verified. |
| Rainscreen and flashing | Furring strips, window/door flashing, and drainage details go in before a single board is hung. |
| Board and batten install | Panels and battens are installed to Hardie spec — correct fastener type, spacing, and expansion gaps. |
| Trim, sealant, and final inspection | Trim details are finished, sealant is applied only where it belongs, and we walk the job before calling it done. |
Maintenance and Moss Prevention Through a Long Wet Season
No siding is completely maintenance-free, but board and batten done right in this climate should need very little:
- An annual rinse-down removes early moss and algae growth before it takes hold in shaded or north-facing sections.
- Keep gutters and downspouts clear so water isn't sheeting down the wall in heavy rain.
- Trim back landscaping that keeps siding shaded and damp — a common driver of moss in yards around Ferndale.
- Check caulked joints every year or two and have any cracked sealant replaced before water gets behind it.
Homes with a properly built rainscreen and ColorPlus-finished Hardie board and batten generally need far less scrubbing and recaulking than wood or vinyl versions of the same style, simply because the material and the finish aren't degrading the way those alternatives do.
What a Correct Board & Batten Job Should Include
- A weather-resistant barrier and rainscreen gap behind the boards, not boards fastened straight to sheathing
- Corrosion-resistant fasteners rated for coastal exposure
- Proper flashing at every window, door, and horizontal trim break
- Manufacturer-spec fastener spacing and board/batten expansion gaps
- Factory-finished panels (ColorPlus) rather than field-painted boards
- A final walkthrough where seams, corners, and flashing are checked before the crew leaves
Cost Factors for Board & Batten in This Area
| Factor | Why It Affects Price |
|---|---|
| Existing wall condition | Rotten sheathing or hidden moisture damage adds repair work before siding can go on. |
| Panel vs. Artisan reveal | Deeper, more dimensional Artisan profiles cost more than standard panel-and-batten. |
| Home height and access | Multi-story sections and tight side yards add labor and staging time. |
| Trim complexity | Corners, window returns, and gable detailing take more time on a vertical profile than a flat wall run. |
| Tear-off scope | Removing and disposing of existing siding versus building over a bare wall changes the labor total. |
Why a Crew That Already Works Ferndale Matters
Board and batten forgives fewer mistakes than lap siding — the seams are more visible, the drainage details are less intuitive, and a crew unfamiliar with wind-driven rain and salt exposure will often skip steps that don't show up as a problem until a few winters in. A crew that regularly works Whatcom County homes already knows to size the rainscreen gap for this rainfall, spec fasteners for the salt exposure, and detail flashing for driving rain instead of copying a install method built for a drier region. That local repetition is what keeps board and batten looking straight and performing well long after the crew has moved on to the next job.
