Anacortes Siding Board & Batten Siding Built for Ship Harbor's Waterfront Exposure
Ship Harbor sits close enough to the water that homes there deal with a different siding environment than a house a few miles inland in Anacortes. Salt-laden air off the strait, wind-driven rain that hits walls sideways instead of falling straight down, and a wet season that can stretch on long enough to grow moss on anything that stays damp too long — all of it adds up to real wear on the wrong siding product. Board and batten is one of the best-looking siding styles for this part of Skagit County, with its clean vertical lines and strong shadow pattern, but it only holds up here if it's built from the right material and installed with this exposure in mind.
This page is about that one job, done right, for that one area: board and batten siding installed on Ship Harbor homes using James Hardie fiber cement — the only siding product we install, anywhere.
What Ship Harbor's Climate Actually Does to Siding
Homeowners closer to the water in Anacortes often assume their siding problems are just "normal Pacific Northwest weather." Some of it is. But proximity to the harbor adds a few specific stresses that inland Skagit County homes see less of:
- Salt air corrosion — airborne salt accelerates the breakdown of exposed fasteners, cheap trim, and any coating that isn't built to resist it.
- Driving rain — wind off the strait pushes rain horizontally into wall assemblies, not just down them, which punishes vertical siding styles with lots of seams and joints.
- Extended moss season — shaded, north-facing, or tree-adjacent walls stay damp for weeks at a stretch, and moss and algae take hold on any surface that can't dry out or resist organic growth.
- Wide temperature and humidity swings — siding that expands and contracts a lot with moisture (like some engineered wood products) works its fasteners loose over years of this cycle.
None of this means board and batten is a bad choice for Ship Harbor — it means the material and the installation details matter more here than they would somewhere drier and more sheltered.
Why We Install Only James Hardie Fiber Cement for This Style
Board and batten can be built from several materials — vinyl, engineered wood, primed spruce, cedar, or fiber cement. We don't install the first four, and it's worth explaining why in plain terms rather than just saying "we don't do that."
Vinyl board and batten
Vinyl board and batten panels are inexpensive and low-maintenance in the sense that they don't need paint, but they're thin, they flex, and in strong coastal wind they can rattle, bow, or pop out of their track. Salt air doesn't rot vinyl, but UV and temperature swings make it brittle over time, and once a panel cracks near the water it's usually a full-run replacement, not a patch.
Engineered wood and primed spruce
These products look close to real wood board and batten at a lower cost, but they're wood at their core — if moisture gets past a seam, a scratch, or a cut edge that wasn't sealed, the material swells and eventually softens from the inside. In a driving-rain environment like Ship Harbor, that's exactly the failure mode we see most.
Real cedar
Cedar has genuine appeal and natural rot resistance, but it still needs regular refinishing, and in a long moss season it needs active upkeep — cleaning, treating, sometimes re-staining — to keep organic growth from taking hold on shaded sides of the house. It's a real material with real maintenance, not a set-and-forget siding.
James Hardie fiber cement
Hardie board and batten is non-combustible, dimensionally stable (it doesn't swell and shrink with every rain the way wood-based products do), and finished with a factory-applied ColorPlus coating that's baked on rather than field-painted — which matters directly for salt air, since a factory finish resists fading and chalking better than most site-applied paint over the long run. Hardie's HZ5 product line is engineered specifically for wetter, harsher climates, which fits the Ship Harbor exposure better than a generic siding spec.
What a Correct Board & Batten Installation Actually Involves
Board and batten looks simple from the street — wide boards, narrow battens over the seams — but the style has more failure points than lap siding if it's installed carelessly, because every vertical seam is a potential path for water. On a driving-rain site like Ship Harbor, the installation details are what decide whether the siding lasts.
Rainscreen gap
We install with a drainage gap behind the siding rather than face-nailing directly to the wall. That gap lets any water that does get past the surface drain and evaporate instead of sitting against the sheathing — important on walls that take rain sideways.
Flashing at every horizontal break
Window heads, door heads, and any horizontal trim need proper flashing detail, not just caulk. Caulk fails; flashing sheds water by geometry and keeps working after the caulk eventually cracks.
Fastener pattern and spacing
Hardie's published fastening specs exist for a reason — correct nail placement and spacing is what keeps panels from working loose under wind load. This is one of the most common places we see prior board and batten jobs cut corners, on this house and others we've looked at around Anacortes.
Batten placement over structural framing
Battens should land over framing or blocking, not just decoratively over a seam. This is a detail that's easy to skip and hard to see once the job is finished — but it's the difference between battens that stay tight for decades and ones that work loose in a few years of coastal wind.
Board & Batten Product Options
| Approach | How it looks | Best fit |
|---|---|---|
| HardiePanel vertical siding + battens | Clean, consistent panel joints under uniform battens | Full board and batten look on new builds or full re-sides |
| Individual Hardie boards + battens | Slightly more traditional plank-and-batten shadow lines | Homes matching a farmhouse or craftsman look |
| Board and batten as an accent | Mixed with HardiePlank lap siding on gables or entry features | Homes wanting contrast without a full re-side |
ColorPlus finishes are available across these options in a range of colors suited to the muted, natural-toned palette common along this stretch of the Salish Sea coast.
Cost Factors for a Ship Harbor Board & Batten Job
| Factor | Why it moves the price |
|---|---|
| Full re-side vs. accent areas | Whole-house board and batten costs more than using it as a gable or entry accent over lap siding |
| Existing siding removal | Tear-off and disposal of old vinyl, wood, or damaged siding adds labor before install starts |
| Wall condition underneath | Rot repair or sheathing replacement found once old siding comes off is common on older coastal homes |
| Home height and access | Multi-story walls facing the water often need staging or lift access, which affects labor time |
| Trim and flashing detail | Homes with more window and door openings need more flashing work per square foot of wall |
We give firm numbers only after walking the actual house — anyone quoting a solid price over the phone for a coastal Anacortes home hasn't seen what's under the existing siding.
Our Process
- On-site assessment — we look at the current siding, wall condition, and exposure on each elevation before quoting anything.
- Detailed proposal — scope, product selection, color, and price, in writing, no pressure.
- Removal and prep — old siding comes off, sheathing and framing get inspected and repaired where needed before anything new goes up.
- Rainscreen and flashing install — drainage gap, window and door flashing, and weather barrier detail get done before the visible siding goes on.
- Hardie board and batten installation — installed to manufacturer fastening specs, with battens set over framing.
- Final walkthrough — we go over the finished job with the homeowner before calling it done.
Maintenance Homeowners Should Actually Expect
- Rinse down shaded or north-facing walls once or twice a year to discourage moss and algae buildup
- Check caulk lines at trim and corners annually — even good caulk is a maintenance item, not a permanent seal
- Keep gutters and downspouts clear so runoff isn't dumping extra water onto one section of wall
- Trim back vegetation that keeps a wall shaded and damp longer than the rest of the house
- Have any impact damage (branches, debris in storms) inspected rather than left — fiber cement resists most damage but a cracked panel should still be addressed
Why Hiring a Crew That Already Works Ship Harbor Matters
Siding contractors who mostly work drier, inland jobs sometimes install to a generic spec and call it done. A crew that regularly works this stretch of Anacortes and Skagit County waterfront knows which elevations take the worst of the wind-driven rain, which walls are prone to moss because of shade and airflow, and where salt air has historically been hardest on trim and fasteners on similar homes nearby. That local pattern recognition shows up in small decisions — where to add extra flashing attention, which side of the house needs the drainage gap done most carefully — that a generic install spec doesn't capture.
