Ferndale Board & Batten in Custer: A Style That Has to Earn Its Keep
Board and batten has a look Custer homeowners keep asking for — clean vertical lines, deep shadow reveals, a farmhouse-meets-Pacific-Northwest character that works on everything from a modest rambler to a new build on acreage. But out here, style is only half the job. Custer sits in a stretch of Whatcom County that catches salt-laden air off the water, long stretches of driving rain, and a moss season that can run most of the year in shaded spots. A vertical siding profile that isn't detailed correctly will show every one of those problems within a few winters — cupped boards, streaked battens, soft trim, moss creeping up from the base. Done right, board and batten is one of the most durable-looking sidings you can put on a house. Done wrong, it's one of the least forgiving.
What Custer's Climate Actually Does to Vertical Siding
Salt Air and Coastal Exposure
Properties in this part of Whatcom County are close enough to the water that airborne salt is a real factor in material selection, not a theoretical one. Salt accelerates corrosion on exposed fasteners and metal flashing, and it breaks down cheap coatings and finishes faster than inland exposure would. Any board and batten system here needs fasteners and trim details rated for that exposure — this isn't optional trim-level detail, it's the difference between siding that looks fine at year 15 and siding that's chalking and rusting at year 6.
Driving Rain and Wind-Driven Moisture
Board and batten is a vertical system, which means every seam, joint, and batten strip is a potential path for wind-driven rain to get pushed sideways and upward behind the cladding. In a climate that sees sustained rain events rather than quick passing showers, that matters. The water-resistive barrier behind the siding, the flashing at every horizontal transition, and the gap and fastening pattern at each batten all have to be built assuming rain will hit this wall at an angle, repeatedly, for months at a time.
Moss and Shade Season
Whatcom County's tree cover and long overcast stretches mean north-facing and shaded walls stay damp far longer after a storm than they would in a drier climate. Moss and algae don't just look bad — sustained organic growth holds moisture against the siding surface, which is exactly the condition that degrades untreated wood substrates and lifts poor-quality paint films. A siding material's finish and moisture tolerance matter more here than in almost any other region we could name.
What a Correct Board & Batten Installation Actually Involves
Board and batten looks simple — vertical panels with strips covering the seams — but the parts you don't see are what determine whether it lasts. A correct installation includes:
- A continuous water-resistive barrier installed shingle-fashion behind the panels, with every penetration and seam properly lapped and sealed
- Rainscreen or furring strips where called for, so water that does get behind the cladding has somewhere to drain and dry instead of sitting against the sheathing
- Correct batten spacing and fastening — battens fastened into structural framing, not just through the panel into open air
- Proper flashing at every horizontal break: window and door heads, the water table at the foundation line, and any roof-to-wall intersection
- Factory-finished panels and trim wherever possible, so field-cut edges are the only places relying on site-applied sealant or paint
- Fastener patterns and clearances that match the manufacturer's engineering, not a generic "close enough" spacing
Skip any one of these and the siding may look right on installation day and still fail early. This is where a lot of board and batten problems actually start — not with the material, but with a crew treating a vertical rain-shedding system like it's just a flat panel with sticks nailed over the seams.
Why We Only Install James Hardie for Board & Batten
We install James Hardie fiber cement exclusively — we don't offer vinyl board and batten, LP SmartSide, Cemplank, Allura, primed spruce, or cedar board and batten, and we're upfront about why. Fiber cement is non-combustible, dimensionally stable, and holds a factory-applied ColorPlus finish that's baked on and warranted against fading and peeling — none of which is true of raw wood siding, and none of which vinyl or engineered wood products match in the same way. Hardie's HZ5 product line is specifically formulated for wetter, harsher climates like ours, which is a meaningful distinction in a region dealing with the rain and salt exposure Custer sees. We'd rather stand behind one system we know performs than offer a menu of products with different long-term outcomes and try to sell homeowners on whichever is cheapest that month.
For board and batten specifically, Hardie offers two approaches: HardiePanel vertical siding paired with HardieTrim battens for the classic look, or individual HardiePlank boards installed vertically with battens over the seams for a slightly more traditional profile. Both are engineered fiber cement, both take the ColorPlus finish, and both are built to be installed with the rainscreen and flashing details this climate demands.
Board & Batten Material Comparison
| Material | Moisture Behavior in This Climate | Maintenance | Typical Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Engineered HZ5 formulation; dimensionally stable in sustained wet conditions | Occasional wash; factory finish resists moss staining better than raw wood | 30+ years with correct install |
| Cedar / primed wood | Absorbs moisture, prone to cupping and rot in shaded, damp areas | Regular repainting/staining and moss treatment | 10-20 years, highly dependent on upkeep |
| Vinyl board and batten | Doesn't rot, but seams and battens can allow water intrusion behind panels; can warp under heat/cold cycling | Low, but limited repair options if damaged | 15-25 years |
| LP SmartSide (engineered wood) | Treated to resist moisture, but any breach in the factory seal exposes wood substrate to rot | Moderate; edge sealing critical at cuts and seams | 20-30 years, install-sensitive |
This isn't a claim that every other product is unusable — it's why, as a standardization decision, we put fiber cement on the homes we work on and don't offer the alternatives.
Our Process for a Custer Board & Batten Project
- On-site assessment — we look at wall orientation, existing moisture damage, shade exposure, and how the current siding and trim have held up, which tells us a lot about what this specific wall needs
- Substrate check and repair — any soft sheathing or existing rot gets addressed before new siding goes on; covering a problem never fixes it
- Water-resistive barrier and drainage plane installation — done to spec for the panel and batten system, not shortcut
- Flashing at every transition — windows, doors, the water table, and roof lines
- Panel and batten installation — fastened to manufacturer spec, into framing, with correct reveal and spacing
- Final trim, caulking, and touch-up — using Hardie-compatible products so the finish performs as warranted
Maintenance and What to Expect Over Time
Fiber cement board and batten is low-maintenance, not no-maintenance. In Custer's climate, that means an occasional gentle wash to keep moss and mildew from taking hold on shaded elevations, a periodic look at caulking around windows and trim, and keeping gutters and downspouts directing water away from the wall rather than sheeting down it. Because the ColorPlus finish is factory-applied and warranted, you're not looking at a repaint cycle the way you would with wood — but a five-minute seasonal walk-around still catches small issues before they become expensive ones.
Why Hiring a Crew That Already Works in Custer Matters
Board and batten installed to a generic national spec can still fail in a specific microclimate. A crew that already works in this part of Whatcom County knows which walls take the worst of the wind-driven rain, which sites need extra attention to shade and moss exposure, and how the salt air here changes fastener and flashing choices. That's not something you get from a crew rotating through unfamiliar territory — it's built from doing this work, on homes like yours, in this exact climate, over and over.
Questions Worth Asking Before You Sign a Contract
- Will the crew install a rainscreen or drainage gap behind the panels, or fasten directly to the sheathing?
- What fastener material and coating are they using, given the salt air exposure?
- Who handles flashing at windows, doors, and the water table — is it included, or treated as an add-on?
- Is the product factory-finished, or will the crew be field-painting or staining after install?
- What does the warranty actually cover — material, labor, or both — and who backs it?
