Bellingham Why Board & Batten Is Everywhere in Bellingham Right Now
Board and batten has become one of the most requested siding profiles in Bellingham and across Whatcom County. It reads as modern farmhouse on a new build, craftsman on a bungalow, and clean and understated on just about anything in between. The look comes from wide vertical boards or panels with a narrow strip — the batten — covering each seam. It's a striking style. It's also one of the profiles where material choice and installation quality matter more than almost any other, because of how the design itself is built.
The Physics of a Vertical Seam
Horizontal lap siding sheds water by design — each course overlaps the one below it, so gravity does most of the work. Board and batten runs vertically, and every batten covers a joint between two panels. That joint is a place where wind-driven rain can be pushed sideways and upward, especially in a location like Bellingham where storms regularly come in off the Strait of Georgia with real horizontal force behind the rain. Add in salt air near the water, a wet season that runs long, and the shade and dampness that keep moss established on north-facing walls for much of the year, and you've got a profile that will find any weakness in the material or the installation eventually.
That's not a reason to avoid board and batten. It's a reason to be picky about what it's built out of and how it's put on the wall.
Why We Don't Build This Profile in Wood-Based Products
Board and batten is offered in primed spruce, engineered wood products like LP SmartSide, and traditional cedar. Each has real strengths — cedar's grain and warmth, engineered wood's workability, primed spruce's low upfront cost. But every one of them shares a common vulnerability: the core material is wood-based, and wood-based cores swell, wick moisture, and eventually break down faster at cut edges, fastener penetrations, and butt joints when they stay damp. Battens create dozens of extra seams and fastener lines compared to a plain lap job, which means dozens of extra places where that vulnerability gets tested — right in a climate that doesn't dry out quickly between storms.
We made the call years ago to install James Hardie fiber cement exclusively, and board and batten is one of the clearest examples of why. Hardie panels and trim are engineered from cement, sand, and cellulose fiber — non-combustible, dimensionally stable, and largely indifferent to the moisture cycling that gives wood-based siding trouble over time.
How We Build It: HardiePanel and HardieTrim
Our board and batten installations use HardiePanel vertical siding as the field material with HardieTrim boards installed over the seams as the battens. A few details separate a board and batten job that lasts decades from one that causes problems in five years:
- Rainscreen gap: We install over a drainage gap rather than directly against the weather barrier, so any moisture that does get behind the cladding has somewhere to go and can dry out.
- Panel and batten spacing: Hardie specifies exact gaps at panel edges and batten overlap to allow for material movement without stressing the joint.
- Fastening pattern: Battens and panels are fastened per Hardie's engineering specs — not just "close enough" — because fastener placement is one of the most common points of failure in board and batten work done off-spec.
- Flashing at every horizontal transition: window heads, belly bands, and the base of the wall get properly lapped flashing, since a vertical profile relies on flashing to do the job gravity handles automatically on lap siding.
- Grade and deck clearance: panels stay clear of soil, decking, and roof lines by the margin Hardie requires, which matters even more with moss and standing moisture common on ground-level surfaces here.
ColorPlus vs. Field-Painted Battens
One quiet failure point on wood-based board and batten is the batten itself — it's often field-painted, and paint film on a narrow vertical strip exposed on both edges is one of the first things to crack and let moisture in. We spec HardieTrim battens in ColorPlus factory finish wherever possible: a baked-on finish applied under controlled conditions, backed by its own finish warranty, so you're not depending on a field paint job holding up on the most exposed component of the whole wall.
What You Get With Hardie Board & Batten
| Factor | What It Means |
|---|---|
| Material | Fiber cement — non-combustible, moisture- and moss-resistant compared to wood-based cores |
| Finish | ColorPlus factory finish available on trim and field panels, reducing field-paint dependency |
| Warranty | Manufacturer warranty transferable to a future homeowner, backing both material and finish |
| Installation | Installed to Hardie's published specs for rainscreen, fastening, and flashing — not shortcuts |
