Bellingham Board & Batten Siding, Done Right for Ferndale
Board and batten has become one of the most requested siding styles in Whatcom County, and Ferndale homeowners have good reason to like it. The vertical lines read as clean and modern on new builds, but the same profile also works beautifully on farmhouses, barns-turned-homes, and the mix of older and newer construction scattered around Ferndale's agricultural and residential streets. It's a strong look. But board and batten is also a style that punishes a sloppy install faster than standard lap siding does, and Ferndale's weather is not gentle on vertical siding joints, seams, or battens that were nailed on without a plan for water.
This page covers what board and batten siding actually needs to survive here, what a correct installation involves, and why we only install it in James Hardie fiber cement rather than the vinyl, engineered wood, or primed spruce versions you'll see marketed for the same look.
What Ferndale's Climate Actually Does to Vertical Siding
Ferndale sits close enough to Bellingham Bay and the Strait of Georgia that salt-laden air is a real factor on exterior materials, not a theoretical one. Add Whatcom County's long stretch of driving rain each fall and winter, and you've got two forces working against any siding system: corrosion of exposed metal fasteners and trim, and water finding its way behind the cladding through wind-driven rain that doesn't just fall straight down.
Board and batten makes this more demanding because it relies on vertical seams and narrow battens instead of overlapping horizontal boards shedding water downward by design. Every batten joint, every panel seam, and every point where the siding meets a window, door, or roofline is a place water can get pushed inward if the assembly wasn't built with drainage in mind.
Then there's moss. Whatcom County's combination of shade, moisture, and mild temperatures gives moss and algae a long growing season on north-facing and tree-shaded walls. On some siding materials that's cosmetic. On others, sustained moss growth holds moisture against the surface and accelerates rot or delamination underneath. What board and batten is made of, and how it's installed, determines whether moss season is a minor cleaning chore or a real threat to the wall assembly.
What We Install: James Hardie, Not the Alternatives
We install James Hardie fiber cement board and batten siding exclusively. We do not install LP SmartSide, vinyl board and batten panels, Cemplank, Allura, primed spruce, or cedar board and batten. That's a deliberate standard, not an oversight, and it's worth explaining honestly.
Vinyl Board and Batten
Vinyl board and batten panels are inexpensive and go up fast, and for a mild, dry climate they can be a reasonable budget option. In a wet, salt-influenced climate like Ferndale's, vinyl's weaknesses show up faster: it expands and contracts significantly with temperature swings, which stresses the fastening system over time, and it can warp or fade under prolonged UV and moisture exposure. It also doesn't hold paint well if a homeowner ever wants to change the color down the road.
LP SmartSide and Engineered Wood
Engineered wood products like LP SmartSide use a wood strand core with a resin-treated coating. It looks good fresh off the truck and installs easily, but any engineered wood product depends entirely on that outer coating staying intact. Once a fastener hole, cut edge, or impact point is exposed and not properly sealed, the wood-based core can absorb moisture and swell or deteriorate. In a climate with this much sustained rain and humidity, we've seen that failure mode too often to recommend it.
Primed Spruce and Cedar
Real wood board and batten has genuine appeal — it's a traditional look for a reason. But solid wood needs a maintenance commitment most homeowners underestimate: repainting or resealing on a real schedule, careful caulking, and vigilance about moss and mildew, since wood is an organic material that mold and rot organisms can actually feed on. Cedar's natural rot resistance helps, but it's not immunity, especially with the moisture load Whatcom County delivers.
Why James Hardie
James Hardie fiber cement is cement, sand, and cellulose fiber — it does not have an organic core for moisture to break down, and it's non-combustible. The ColorPlus factory finish is baked on under controlled conditions rather than field-applied, which gives it better fade and chip resistance than a job-site paint job. Hardie's HZ5 product line is engineered for climates that see sustained moisture and freeze-thaw cycling, which is a reasonable description of a Whatcom County winter. It also carries a strong transferable warranty backed by a manufacturer with decades of track record in coastal Pacific Northwest markets — not a new entrant chasing the board and batten trend.
What Correct Board & Batten Installation Actually Involves
The style is simple. The installation is not, if it's done to hold up. Here's what we build into every board and batten project regardless of the home's age or style.
Drainage Plane and Rainscreen Gap
Vertical siding needs a continuous water-resistive barrier behind it and, in most cases, a furring strip or rainscreen gap that lets any water that does get behind the panels drain and dry out instead of sitting against the sheathing. This is the single biggest difference between a board and batten wall that lasts decades and one that starts showing rot at the bottom courses within a few years.
Fastening and Batten Spacing
Battens need consistent spacing and fastening that accounts for the underlying panel's expansion and contraction — over-driven or under-driven fasteners are one of the most common board and batten failure points we get called to fix on other contractors' work. We follow James Hardie's published fastening schedules rather than a generic "close enough" approach.
Trim, Flashing, and Joints
Every horizontal transition — window heads, door tops, roof-to-wall junctions — needs proper flashing, not just caulk. Caulk is a maintenance item and a first line of defense; flashing is what actually keeps water out long-term. On a style with this many vertical seams, getting the top and bottom terminations right matters more than it does on lap siding.
Board & Batten Material Comparison
| Material | Moisture Resistance | Maintenance | Typical Lifespan | Our Position |
|---|---|---|---|---|
| James Hardie Fiber Cement | Excellent — non-organic core | Low — factory finish, periodic wash | 30+ years to spec | What we install |
| Vinyl Board & Batten | Fair — seams and fasteners are weak points | Low, but limited repair options | 15-25 years | Not installed |
| LP SmartSide / Engineered Wood | Good if coating stays intact | Moderate — inspect cut edges and fasteners | 20-30 years | Not installed |
| Cedar / Primed Spruce | Fair — organic material | High — repaint/reseal on schedule | 15-30 years with upkeep | Not installed |
Our Process for a Ferndale Board & Batten Project
We start with a walk-around assessment of the existing wall assembly, not just the surface siding — sheathing condition, existing moisture damage, and how the home's roofline and grading direct water toward the walls all factor into the plan. From there:
- Full tear-off of failing siding and inspection of sheathing, with any rot or water damage repaired before anything new goes on.
- Installation of a continuous water-resistive barrier and rainscreen furring for drainage behind the panels.
- James Hardie panel and batten installation to manufacturer fastening specifications, including correct batten spacing and fastener depth.
- Flashing at every window, door, and roof transition, with caulking used as a supplement, not a substitute.
- Final walk-through so you understand what was done and what, if anything, needs periodic attention.
Maintenance in a Moss-Prone Climate
James Hardie siding installed correctly is low-maintenance, not no-maintenance. A short seasonal checklist keeps it performing the way it's designed to:
- Rinse siding gently once or twice a year, focusing on north-facing and shaded walls where moss and algae take hold first.
- Keep gutters clear so overflow isn't running down the wall face during heavy fall rain.
- Trim back vegetation and tree limbs that keep a wall section shaded and damp longer than the rest of the house.
- Inspect caulking at trim and window joints yearly and have gaps re-sealed before they become entry points.
- Watch for any soft spots or discoloration near the bottom courses, which is where drainage problems show up first.
Why Hiring a Crew That Already Works in Ferndale Matters
Board and batten's vulnerability to poor installation means the contractor matters more here than it does for simpler siding styles. A crew that already works Whatcom County jobs understands the difference between siding a home a mile off Bellingham Bay and one further inland, knows what local wind-driven rain patterns actually do to vertical joints, and isn't learning Ferndale's climate on your project. We also know local permitting expectations and the kind of inspection questions that come up on siding replacement in this county, so there are no surprises mid-project.
