Bellingham Siding Board and batten has become one of the most requested looks in Whatcom County — vertical lines, deep shadow reveals, a clean modern-farmhouse or craftsman profile that works on everything from a Fairhaven bungalow to a new build out toward Ferndale. It's a great look. It's also one of the easier siding styles to get wrong, and in a climate like ours, getting it wrong shows up fast.
Why Board & Batten Is Different From Lap Siding
Traditional horizontal lap siding is designed to shed water the way shingles do — each course overlaps the one below it. Board and batten flips that logic. You've got vertical boards (or panels) with battens covering the seams, and every one of those vertical seams is a place water can find its way behind the cladding if it isn't detailed correctly. There's less built-in overlap doing the work for you, so the installation itself has to carry more of the load.
That matters everywhere, but it matters more here. Bellingham sits close enough to the water that salt-laden air is a real factor on fasteners and finishes, and our fall-through-spring stretch brings weeks of driving, wind-blown rain rather than gentle vertical showers. Add a long moss season where north-facing walls and shaded elevations stay damp for months, and you've got a climate that will find every shortcut in a board and batten installation within a few years, not a few decades.
Where Board & Batten Installations Go Wrong
Most board and batten failures we get called out to inspect trace back to a handful of predictable issues:
- No drainage plane behind the boards. Vertical siding needs a rainscreen gap or properly furred-out installation so any water that gets behind the cladding can drain and dry, rather than sitting against the sheathing.
- Battens face-nailed through both boards and substrate without room to move. Wood-based products expand and contract with moisture; pin them down tight in both directions and they cup, split, or pop fasteners.
- Butt joints and bottom edges left unsealed or unflashed. Every horizontal joint and every point where a board meets a window, door, or foundation is a potential water entry point if it isn't flashed and back-primed correctly.
- Cheap or under-engineered material carrying the whole look. Thin, unstable substrates flex and telegraph every seasonal moisture swing straight into the finish — cracking paint lines, cupped boards, and visible seams within a few years.
None of these are exotic problems. They're basic building-science details that get skipped when a crew is moving fast or when the material underneath the finish isn't dimensionally stable enough to forgive minor installation variance.
Why We Install Board & Batten in James Hardie Only
We install James Hardie fiber cement exclusively, and board and batten is one of the clearest examples of why. Hardie's vertical siding options — whether run as individual HardiePanel with battens, or as a true board-and-batten profile — are engineered fiber cement, not wood or wood-composite. That means the boards themselves don't swell, rot, or delaminate the way wood-based battens can when they take on moisture season after season, which is exactly the stress a coastal Whatcom County wall sees.
A few specifics that matter for this particular style:
- Dimensional stability. Fiber cement moves far less with humidity swings than wood or wood-composite panels, so butt joints and batten lines stay tight and straight instead of gapping open over a few winters.
- ColorPlus factory finish. Board and batten lives or dies visually on crisp, consistent color along every reveal line. A factory-baked finish holds its color and resists the fading and touch-up patchwork that field-painted wood battens eventually need.
- Climate-engineered HZ formulation. Hardie's HZ10 product line is formulated for the wetter, milder Pacific Northwest climate zone specifically — not a generic national spec — which lines up with what a Bellingham exterior actually needs to handle.
- Non-combustible material. It's not the headline reason homeowners choose board and batten, but it's a real, permanent advantage over wood-based siding systems.
We don't install LP SmartSide, vinyl, cedar, or primed spruce board and batten, and the reasoning isn't that those materials can't look good going up — it's that a vertical siding style with fewer built-in water-management redundancies needs a substrate that won't move, swell, or need repainting every few years to keep its lines straight. James Hardie is the product we're willing to warranty and stand behind for this style in our climate.
Getting the Installation Right
Even with the right material, board and batten is a detail-driven install. A correct job includes a rainscreen or drainage gap behind the cladding, proper flashing at every horizontal transition and penetration, batten fastening that allows for material movement, and manufacturer-spec fastener patterns and edge clearances throughout. This isn't a style to have installed by whoever's cheapest or fastest — the visual appeal of board and batten depends entirely on straight lines and tight joints holding up over time, and that only happens when the building science underneath is done correctly the first time.
