Anacortes Siding Board and batten is one of the oldest siding patterns in the Pacific Northwest, and it's having a real moment again — you'll see it on new builds around Anacortes and on older homes getting a full exterior refresh. The vertical lines read as clean and modern on a contemporary build, or classic and farmhouse-simple on a craftsman. But "board and batten" is a look, not a single product, and the material behind that look matters a lot more here than in a dry climate. Skagit County gets salt air off the water, driving rain that hits siding sideways, and a long stretch of the year where north-facing walls barely dry out between storms. That combination is hard on anything that isn't dimensionally stable and properly sealed.
What "Board and Batten" Actually Means
The traditional version is wide vertical boards with a narrower strip — the batten — covering each seam. It was originally a barn-building technique: cheap, fast, and it shed water reasonably well as long as the boards stayed put. The problem with the original method in wood is that boards move with moisture, seams open up, and water gets behind the wall assembly. In a marine climate, that's not a someday problem, it's a five-to-ten-year problem.
Modern fiber cement solves the movement issue by using a material that's dimensionally stable across wet and dry cycles, so the reveal lines stay straight and the seams stay tight for decades instead of a few seasons.
The Two Ways to Build It in Fiber Cement
- Panel and batten: Large vertical fiber cement panels installed first, then battens fastened over the seams. This is the more common and generally more weathertight approach — fewer horizontal joints, fewer places for water to find a way in.
- Individual board and batten: Narrower vertical boards with battens over each seam, giving a tighter, more traditional rhythm. It takes more layout precision and more fasteners, but on the right home it's a distinctive look.
Both rely on the same fundamentals underneath: proper flashing at every horizontal transition, a drainage plane behind the siding, and fasteners driven to the manufacturer's exact spec — not just "close enough."
Why We Only Build This in James Hardie Fiber Cement
Board and batten in real wood or engineered wood products looks fine on day one. The issue shows up at the cut ends and the seams, where these products are most vulnerable to moisture intake — and vertical siding has a lot of seams by design. Once water gets into an end grain or an unsealed edge, swelling and softening follow, and on a home exposed to Rosario Strait weather, that clock runs faster than it does inland.
James Hardie's fiber cement is cement, sand, and cellulose fiber — it doesn't absorb and swell the way wood-based products do, and it isn't a food source for the moss and mildew that thrive in our wet season. That's the whole reason we standardized on it: we're not interested in installing a siding system that looks great at handoff and needs real attention again inside a decade. It's also why we won't put up vinyl board and batten profiles — vinyl can look convincing from the street, but it's a thin material that shows its limitations up close and doesn't hold paint if you ever want to change the color.
Product Lines and Where They Fit
| Line | Best for |
|---|---|
| HardiePanel vertical siding | Full walls, gable ends, modern and farmhouse builds |
| Artisan Collection | Higher-end, tighter reveals, historic or craftsman detailing |
| HZ5 formulation | Homes in our marine, high-moisture climate zone — engineered for wetter, harsher weather cycles |
Hardie engineers its HZ product lines by climate zone rather than shipping one formulation nationwide. For Anacortes and the rest of Skagit County, that means a product actually engineered for salt-air exposure and sustained damp weather, not a generic version that happens to be sold here too.
Color: Factory-Baked vs. Field-Painted
Board and batten lives or dies on straight lines and consistent color, which is exactly where ColorPlus factory finish earns its keep. It's baked on and cured before the boards ever leave the plant, so you get uniform color and sheen across every board — no lap marks, no touch-up mismatch, and a finish that's substantially more resistant to fading than field-applied paint. It also carries its own dedicated finish warranty, separate from the product warranty on the fiber cement itself. Field-painted Hardie is available too, useful for custom colors, but ColorPlus is the lower-maintenance path for most homeowners.
Installation Details That Actually Matter
- Battens fastened with the correct spacing and gap over each seam — not just nailed tight, which can trap moisture and telegraph stress cracks.
- Rainscreen or drainage gap behind the panels so incidental moisture has somewhere to go.
- Flashing at every window head, deck ledger, and roof-to-wall transition — the majority of siding failures we see start at these transitions, not in the field of the wall.
- Fasteners matched to Hardie's published schedule for exposure and substrate.
A board and batten wall installed to spec should look as straight in year fifteen as it did on install day. That's the standard we hold every job to, and it's backed by James Hardie's transferable warranty, which follows the house if you sell.
