Anacortes Exterior A Style That Fits Fidalgo Island
Board and batten has become one of the most requested siding profiles on Fidalgo Island — wide vertical boards with narrow strips covering the seams, used on full exteriors, gable ends, and accent walls on everything from farmhouse remodels to newer coastal-modern builds around Anacortes. It reads clean and vertical, it photographs well against the water and evergreens this area is known for, and it holds up to scrutiny on a home that's visible from the road or the shoreline.
But board and batten is also one of the least forgiving siding profiles to get wrong. Every seam is a potential water path, every batten is a fastening decision, and on Fidalgo Island those decisions get tested by weather that's harder on siding than most of the country ever sees.
What Salt Air, Driving Rain, and Moss Season Actually Do
Anacortes sits surrounded by saltwater — Guemes Channel, Fidalgo Bay, the Rosario Strait — and homes here take on a steady dose of airborne salt that most inland Skagit County properties don't deal with. Salt air is corrosive to exposed metal fasteners, trim flashing, and cheap hardware, and it accelerates fading and chalking on lower-grade siding finishes.
Then there's the rain. Fidalgo Island gets driving, wind-pushed rain off the water, not just straight-down drizzle. On a vertical board and batten wall, wind-driven rain finds its way sideways into laps and seams that a flatter, more forgiving siding style might shed without issue. If the water-resistive barrier, flashing, and drainage plane behind the boards aren't installed correctly, that moisture doesn't just sit on the surface — it gets behind it.
And then there's moss season, which on Fidalgo Island isn't really a season so much as most of the year. Shaded, north-facing walls under the tree canopy common to this area stay damp long after a storm has passed, and any siding material that can absorb or hold moisture becomes a place for moss, algae, and mildew to take hold.
None of this makes board and batten a bad choice for Fidalgo Island — it just means the material and the installation both have to be right for the exposure.
Why We Build It in James Hardie Fiber Cement — Not Wood, Vinyl, or LP
We install James Hardie fiber cement exclusively, and board and batten is one of the clearest examples of why. This profile depends on tight, straight seams and boards that stay flat over time — and that's exactly where wood, vinyl, and engineered wood siding tend to struggle in a marine climate.
| Material | How It Handles This Climate | Long-Term Concern on Fidalgo Island |
|---|---|---|
| Cedar or primed wood board & batten | Absorbs moisture at end grain and seams; needs a sound paint film to stay protected | Repainting cycles, cupping/warping boards, rot at the base and around battens |
| Vinyl vertical/board & batten panels | Won't rot, but expands and contracts with temperature and can warp or pull loose at fasteners | Fading, brittleness in cold snaps, visibly \"plastic\" look up close |
| LP SmartSide (engineered wood) | Wood-based core is more moisture-resistant than raw lumber but still wood at heart | Edge swelling and delamination risk if caulking or flashing fails |
| James Hardie fiber cement | Cement-based core doesn't feed rot, doesn't swell with moisture, factory-cured ColorPlus finish | Requires correct installation (fastening, flashing, gapping) to perform to spec |
Fiber cement isn't magic — it still has to be installed correctly to perform. But it removes the two biggest failure points we see on wood and engineered-wood board and batten in this climate: a core material that can absorb and hold water, and a paint film that has to be maintained on a strict cycle or it starts failing at the seams first.
What We Don't Install, and Why
We get asked regularly about cedar board and batten, vinyl vertical siding, and LP SmartSide. All three have a place in the market and can look good the day they go up. Our reasoning for standardizing on James Hardie isn't that those products are junk — it's that we don't want to be back on a Fidalgo Island roof or ladder in five years dealing with cupped cedar boards, brittle vinyl, or swollen LP edges that this specific climate is particularly good at finding.
The Hardie Board & Batten System, Explained
James Hardie's board and batten look is built from HardiePanel vertical siding with HardieTrim battens fastened over the panel seams — not a single flimsy panel stamped to look like boards. The panel material itself is engineered to Hardie's HZ5 climate specification, which is the version built for the Pacific Northwest's wet, marine-influenced weather rather than a generic national spec.
The finish matters as much as the material. We use Hardie's ColorPlus factory-applied finish, which is baked on under controlled conditions rather than field-painted, giving more even coverage and better fade and chip resistance than a job-site paint job — which matters on a wall that's going to take direct salt air and sun off the water.
Getting the Installation Details Right
Most board and batten problems we get called to fix trace back to installation shortcuts, not the material. On Fidalgo Island specifically, we pay close attention to:
- Drainage plane and rainscreen gap: a gap behind the siding lets any moisture that does get past the boards drain and dry out instead of sitting against the wall assembly.
- Flashing at every horizontal transition: window heads, roof-to-wall intersections, and any horizontal trim need proper flashing so wind-driven rain can't work its way upward or sideways.
- Corrosion-resistant fasteners: given the salt air off the surrounding water, we use fasteners rated for coastal/marine exposure rather than standard hardware that can streak or corrode over time.
- Correct fastening pattern for wide boards: board and batten panels need to be fastened per Hardie's spec to avoid buckling, oil-canning, or loosening as the material and framing move seasonally.
- Sealed, not just caulked, seams: using the right sealant at the right joints — not caulking every seam as a catch-all — so the assembly can still drain and dry as designed.
Our Process, Start to Finish
- On-site assessment of the home's exposure — which walls face prevailing wind and rain, which stay shaded and damp longest, and what the existing siding and sheathing condition looks like.
- Removal of old siding and inspection of the sheathing and existing moisture barrier for hidden rot or damage before anything new goes up.
- Installation of a new water-resistive barrier and rainscreen gap system.
- Installation of flashing, trim, and corner details before the field panels go on.
- Installation of HardiePanel vertical siding and HardieTrim battens per James Hardie's fastening and gapping specifications.
- Sealing at the joints and penetrations that require it, and factory-matched touch-up where needed.
- Final walk-through and cleanup.
Living With Board & Batten on Fidalgo Island
Correctly installed Hardie board and batten is low-maintenance, not zero-maintenance. Shaded or north-facing walls on Fidalgo Island can still collect surface moss and algae over time, the same as any exterior surface in this climate — it's a cosmetic, surface-level issue on fiber cement rather than a structural one, and it typically comes off with a gentle soft-wash rather than harsh scrubbing or high-pressure blasting, which can damage the finish. It's also worth a yearly look at caulked joints and trim intersections, since sealant is the one component in the whole system that has a service life shorter than the siding itself.
What This Job Typically Costs
Board and batten pricing on Fidalgo Island varies more than a lot of homeowners expect, mostly because of scope and access rather than the siding material itself.
| Cost Factor | Why It Moves the Price |
|---|---|
| Full exterior vs. accent walls/gables only | Total square footage of panel, batten, and trim material |
| Tear-off of existing siding | Removal and disposal, plus any sheathing repair found underneath |
| Number of corners, dormers, and trim details | Board and batten is labor-intensive at every seam and corner compared to lap siding |
| Home height and site access | Multi-story walls, steep lots, and tight waterfront access all add setup time |
| Condition of the underlying wall assembly | Rotted sheathing or an outdated moisture barrier adds repair scope before siding goes on |
We won't quote a number without seeing the home, but any honest estimate should walk through these factors specifically rather than giving a flat per-square-foot price with no context.
Questions to Ask Before You Hire
- Are they licensed and insured to do exterior work in Washington State?
- Are they James Hardie certified, and can they explain the HZ5 specification for this region?
- Do they have recent experience with coastal or waterfront exposure in Skagit County, not just inland siding jobs?
- Does their written scope specifically mention rainscreen gap, flashing details, and fastener type?
- Do they explain the difference between the manufacturer's product warranty and their own workmanship warranty?
