Anacortes Exterior Board & Batten in a Salt-Air Neighborhood
Old Town Anacortes has a housing stock that leans toward simple, upright forms — narrow lots, older cottages, and infill homes where a clean vertical siding profile looks right against the neighborhood's character. Board and batten is a natural fit for that look: wide flat panels or boards with narrow battens covering the seams, giving a home strong vertical lines instead of the horizontal shadow lines of lap siding. It's a classic Pacific Northwest exterior, and it holds up well when it's built for the environment it's going into.
That environment matters more here than almost anywhere else in Skagit County. Old Town's proximity to the water means homes take on salt-laden air almost year-round, combined with driving rain off the Sound and a moss season that can run from fall through late spring. Board and batten has more vertical seams and more fastening points than a lot of other siding styles, which means more places for water to find a way in if the install isn't done correctly. Done right, though, it's one of the more durable and low-drama siding choices for this kind of neighborhood.
What Salt Air, Rain, and Moss Actually Do to Siding Here
Every coastal Skagit County neighborhood deals with weather, but board and batten responds to it in specific ways worth understanding before you commit to the style.
Salt Air
Airborne salt settles on exterior surfaces and accelerates corrosion of any exposed or under-protected metal — fasteners, flashing, trim nails. On board and batten, the battens themselves cover most face fasteners, but the flashing at window heads, corners, and the base of the wall is doing the real work of keeping salt-laden moisture from tracking behind the siding. Cheap or improperly lapped flashing is where salt-air damage shows up first, usually as staining or corrosion streaks long before any structural issue appears.
Driving Rain
Wind off the water doesn't just fall rain straight down — it drives it sideways into vertical seams and batten joints. Board and batten depends on those seams being built to shed water outward, not just caulked and hoped for. A rainscreen gap behind the siding (a small ventilated cavity) is what actually keeps driving rain from becoming trapped moisture, especially on walls that face open water or prevailing weather.
Moss and Persistent Dampness
Anacortes's long damp season, shaded lots, and tree cover common in Old Town all favor moss and algae growth on north-facing and shaded walls. Wood-based sidings absorb moisture that feeds that growth and can soften underneath it. Moss holding water against a wall for months at a time is a slow but real threat to anything that isn't inherently moisture-resistant.
What a Correctly Installed Board & Batten Job Requires
The style is simple to look at, but the installation details are where a good job and a problem job diverge. For this climate, the non-negotiables are:
- A drainage plane (weather-resistant barrier) installed and lapped correctly behind the siding, shingle-style, so water sheds down and out rather than in
- A rainscreen gap or vertical furring behind the boards to let bulk water drain and the wall assembly dry between rain events
- Corrosion-resistant fasteners rated for coastal exposure, set to the manufacturer's pattern and depth — not just "close enough"
- Properly flashed and kicked-out window and door openings so water is thrown clear of the wall, not funneled behind the trim
- Correct board spacing and fastening that accounts for the material's expansion and contraction, so seams don't open up or crack over time
- Sealed, back-primed, or factory-finished board ends and cuts — an exposed raw edge is where moisture gets its first foothold
Skip any one of these and the siding can look fine for a year or two while damage builds behind the surface where nobody's looking. On a home a few blocks from the water, that timeline compresses.
Why We Install This Style Only in James Hardie Fiber Cement
Board and batten is available in wood, engineered wood, vinyl, and fiber cement, and we get asked regularly why we only install it in James Hardie. The honest answer is that this specific siding style depends on tight vertical seams and exposed board faces holding their shape, and that's exactly where the other materials struggle in a salt-air, high-moisture climate like Old Town Anacortes.
| Material | How It Behaves in This Climate |
|---|---|
| Cedar / primed wood | Traditional look, but absorbs moisture at seams and cut ends; needs regular repainting and is more vulnerable to moss and rot in shaded, damp spots |
| Vinyl board and batten panels | Low upfront cost, but can warp or become brittle with age; doesn't hold paint if you ever want a color change, and seams can loosen with expansion/contraction |
| Engineered wood (LP-type products) | Better moisture resistance than raw wood, but still wood-based at the core, meaning cut edges and any breach in the factory coating need diligent maintenance to prevent swelling |
| James Hardie fiber cement | Non-combustible, dimensionally stable in wet-dry cycles, factory-baked ColorPlus finish resists fading and doesn't rely on field-applied paint holding up against salt air |
Fiber cement doesn't swell, rot, or feed moss the way wood-based products can, and it holds its shape at the seams — which is the single biggest factor in whether board and batten still looks sharp after a decade near the water. James Hardie's HZ5 formulation is specifically engineered for climates with heavy moisture exposure, which describes Old Town Anacortes about as well as anywhere in Skagit County.
Color and Finish for Old Town's Older Homes
Board and batten reads differently depending on finish choice. A factory-applied ColorPlus finish means the color is baked on before installation and warrantied against peeling and cracking separately from the product warranty — which matters on a style with this many exposed vertical faces catching direct weather. For Old Town's older homes, we typically see owners lean toward classic, muted tones that complement the neighborhood's existing character rather than high-contrast modern palettes, though that's entirely an aesthetic choice and either direction works structurally.
Our Process on an Old Town Anacortes Home
Every board and batten job we run in this neighborhood follows the same sequence, adjusted for the specific house:
- On-site assessment — we look at the existing wall assembly, sun and wind exposure on each elevation, and any current moisture or moss damage before quoting anything
- Tear-off and substrate check — old siding comes off and we inspect sheathing for hidden rot or damage before it's covered up again
- Weather barrier and rainscreen installation — this is the step that determines whether the siding performs for 30 years or 10
- Flashing at every penetration — windows, doors, hose bibs, vents, and corners, each detailed for this climate's driving rain pattern
- Board and batten installation to manufacturer fastening specs, maintaining correct gaps for material movement
- Trim, caulking, and final inspection — checking every seam and penetration before we call the job done
Because we work Old Town Anacortes regularly, we already have a working sense of which elevations on which streets take the worst of the wind and salt exposure, and we plan flashing and rainscreen detailing accordingly rather than treating every wall the same.
Maintenance Once It's Installed
Correctly installed James Hardie board and batten is low-maintenance, not no-maintenance. A short seasonal routine keeps it that way:
- Rinse salt residue and grime off exterior walls once or twice a year, especially elevations facing open water
- Keep gutters clear so overflow doesn't run down the wall face and feed moss growth at the base
- Trim back vegetation and tree cover that keeps shaded walls damp longer than necessary
- Check caulking at trim and penetrations annually and touch up before gaps open
- Address any impact damage or chipped finish promptly rather than letting it sit through a wet season
What Board & Batten Siding Typically Costs
Board and batten generally runs a bit higher than standard lap siding installation, mainly due to more cut pieces, more seams to flash, and typically more labor per square foot. Real numbers depend heavily on wall condition, home size, and how much repair the substrate needs, but the main cost drivers are:
| Factor | Why It Moves the Price |
|---|---|
| Substrate condition | Rot or moisture damage found during tear-off adds repair costs before new siding goes on |
| Wall complexity | More corners, windows, and dormers mean more flashing and cut work |
| Rainscreen detailing | A properly vented assembly costs more upfront but is what prevents moisture problems later |
| Finish choice | Factory ColorPlus finishes cost more than field-primed but reduce long-term maintenance |
| Site access | Narrow Old Town lots and older foundations can affect staging and scaffolding needs |
We give every homeowner a written estimate that breaks these factors out rather than a single lump number, so you can see exactly what's driving the cost.
Why Local Experience Matters for This Job
Board and batten's performance in this climate comes down entirely to installation quality — the material itself is proven, but the flashing, rainscreen, and fastening details are where a crew's experience with this specific coastal environment shows up. A contractor who's worked Old Town Anacortes homes has already seen which elevations catch the worst driving rain, how moss behaves on the neighborhood's shaded lots, and what older wall assemblies typically need before new siding goes over them. That's the difference between a board and batten install that still looks sharp in fifteen years and one that needs early intervention.
