Board & Batten in a Place Where Weather Doesn't Let Up
Conway sits down in the Skagit River lowlands, a short drive south of Anacortes, where farmland, tidal influence, and marine weather all meet in one small stretch of Skagit County. Homes here take a different kind of beating than houses up on drier ground. The air carries salt off Puget Sound and the Skagit delta, rain comes in sideways more often than straight down, and shaded, low-lying lots hold onto damp air long after a storm has passed. Board and batten siding — with its clean vertical lines, deep shadow lines, and farmhouse-friendly look — is one of the most requested styles we install in this corridor. Done right, it holds up to everything Conway throws at it. Done wrong, it's one of the fastest ways to trap moisture behind a wall.
This page is about that one service, in this one place: what board and batten siding needs to survive in Conway, what a correct installation actually involves, and why we only do it in James Hardie fiber cement.

What Conway's Climate Actually Does to Siding
Three things define the exterior environment around Conway, and each one attacks siding differently.
Salt Air
Proximity to Puget Sound and the Skagit River estuary means airborne salt is a constant, low-level presence. Salt accelerates corrosion on exposed fasteners and metal flashing, and it can slowly break down finishes that aren't engineered to resist it. Any siding product with a factory finish needs to be rated for coastal or marine exposure, not just general weather resistance.
Driving Rain
Skagit County storms frequently arrive with wind, which pushes rain sideways into wall assemblies instead of letting it run straight down and off. Board and batten is especially exposed to this because the vertical boards and battens create seams that run the full height of the wall — every one of those seams needs to be built to shed wind-driven water, not just resist a light drizzle.
Moss and Prolonged Dampness
Low-lying, tree-shaded lots around Conway hold humidity longer than open, higher ground. That extended damp season is exactly what moss, algae, and mildew need to establish themselves on a wall. Once organic growth gets a foothold on a porous or absorbent siding material, it holds moisture against the substrate even longer, which compounds the problem year over year.
Put together, these three conditions mean Conway homes need siding that resists water intrusion at the seams, doesn't feed moss growth, and keeps its finish and fasteners intact under salt exposure — for decades, not just a few seasons.
Why Board & Batten Is a Good Fit for This Area — When It's Built Right
Board and batten has real practical advantages in a wet climate, beyond its farmhouse and modern-craftsman curb appeal. The vertical board orientation sheds water more directly than some horizontal profiles when the underlying assembly is built correctly, and the batten strips add a second layer of coverage over the panel seams — if they're installed with the right gap, fastening pattern, and drainage path behind them. The style also tends to show moss and streaking differently than lap siding; on a properly finished fiber cement board, growth has a much harder time attaching in the first place, which matters given how long Conway's damp season runs.
None of that is automatic, though. Board and batten is more installation-sensitive than standard horizontal lap siding, because every vertical seam is a potential water path if it's not detailed correctly. This is a style where the contractor's technique matters as much as the product.
What a Correct Board & Batten Installation Involves
A board and batten job that will actually hold up in Conway's climate isn't just panels and strips nailed to the wall. It's a full assembly:
- Weather-resistive barrier: A continuous, correctly lapped water barrier goes on before any siding, managing bulk water that gets past the cladding.
- Drainage gap: A rainscreen gap behind the panel lets any incidental moisture drain and dry instead of sitting against the wall sheathing — critical in a climate where things rarely fully dry out between storms.
- Flashing at every penetration: Windows, doors, hose bibs, light fixtures, and vents all need proper flashing integrated with the water barrier, not just caulked over.
- Correct panel and batten fastening: Fasteners driven to the manufacturer's spec, into framing, at the right spacing — not overdriven, not into the field of the panel where it can crack the material.
- Batten placement and spacing: Battens sized and spaced to cover the panel seams fully with room for material movement, not just tacked on for looks.
- Bottom edge and trim detailing: A clean gap and drip edge at the foundation line, and factory or field-finished trim that won't wick water at cut ends.
Skip any one of these steps and you can end up with a wall that looks right for a year or two and then starts showing streaking, soft trim, or paint failure at the seams — problems that are expensive to trace once they're hidden behind finished siding.
Why We Install Board & Batten Only in James Hardie Fiber Cement
We don't offer board and batten in vinyl, LP SmartSide, primed spruce, cedar, or other fiber cement brands. That's a standard we hold across every job, and it applies just as much here in Conway as anywhere else we work.
James Hardie's fiber cement is non-combustible, dimensionally stable, and engineered specifically for wet marine climates through its HZ5 product line, which is built for the Pacific Northwest's moisture and temperature swings. For board and batten specifically, we use Hardie's vertical panel systems paired with Hardie trim battens, finished in the factory-applied ColorPlus coating. That factory finish is baked on and cured under controlled conditions, which gives it far more consistent resistance to fading, moisture, and salt exposure than a field-applied paint job on wood or engineered wood trim ever will.
Fiber cement also doesn't feed moss and mildew the way wood-based products can. It won't absorb water and swell at cut edges, won't delaminate at the panel face, and holds paint and factory finish far longer under sustained damp conditions — which is exactly the failure mode we see most often on older board and batten jobs around Skagit County that used wood or engineered wood.
James Hardie also backs its ColorPlus finished products with a substantial, transferable limited warranty, which matters to homeowners who may sell within the life of the siding. We stand behind our installation on top of that manufacturer coverage.
How Board & Batten Material Options Compare
| Material | Moisture & Moss Resistance | Salt Air Durability | Finish Longevity | Typical Lifespan |
|---|---|---|---|---|
| James Hardie fiber cement | High — non-absorbent, engineered for wet climates | Strong, factory-tested finish | ColorPlus baked-on finish, resists fade | 30+ years with proper install |
| Cedar / primed spruce | Moderate — absorbs moisture, needs regular sealing | Finish degrades faster near salt air | Field-applied paint fails sooner, especially at seams | 10-20 years before major refinishing |
| Vinyl board and batten | Sheds water but traps moisture behind panel if not vented well | Can become brittle; salt haze on surface | Color is through-body but fades and chalks over time | 15-25 years, warps under heat/impact |
| LP SmartSide / engineered wood | Better than raw wood, still moisture-sensitive at cut edges | Edge sealing is critical near salt exposure | Field or factory finish, edge maintenance required | 20-25 years with diligent maintenance |
Our Process for a Conway Board & Batten Project
Every job starts with an honest look at what's actually on the wall now, not an assumption.
- On-site assessment: We check the existing siding, sheathing, and trim for hidden moisture damage — common on older Conway homes where prior siding wasn't detailed for driving rain.
- Tear-off and sheathing check: We remove the old cladding and inspect the sheathing underneath, repairing or replacing any wood that's soft or compromised before anything new goes up.
- Water barrier and drainage plane: A continuous weather-resistive barrier and rainscreen gap go in, giving the wall a real drying path.
- Flashing integration: Windows, doors, and penetrations get flashed and tied into the water barrier correctly, before panels go on.
- Panel and batten installation: James Hardie vertical panels and battens are installed to manufacturer fastening and spacing specs.
- Trim, caulking, and final detail: Corners, bottom edges, and transitions get finished with the right materials and gaps for long-term drainage.
- Final walkthrough: We walk the job with the homeowner before calling it done.
Keeping Board & Batten Looking Right in a Damp Climate
James Hardie fiber cement is low-maintenance, not zero-maintenance. A little seasonal attention goes a long way in a climate like Conway's:
- Rinse the siding once or twice a year to clear salt residue and organic buildup before it takes hold, especially on north-facing or shaded walls.
- Keep gutters clear so water doesn't sheet down the wall face during heavy rain events.
- Trim back landscaping and tree cover that keeps a wall section shaded and damp longer than the rest of the house.
- Check caulking at trim joints and penetrations annually — caulk is a maintenance item even on a fiber cement wall.
- Watch for any soft spots, staining, or paint changes near the base of the wall, where splashback and standing water are most likely.
Why It Matters That We Already Work in Conway and Skagit County
A crew that only occasionally works this far south of Anacortes can miss things that a crew familiar with the area catches automatically — how much wind-driven rain a given exposure actually sees, how long a shaded lot stays damp after a storm, or how salt exposure plays out on a specific orientation. We work throughout Skagit County, including Conway, and that means we're not guessing at local conditions or treating this stretch of the county as an afterthought between bigger jobs elsewhere. We show up knowing what this climate does to a wall over ten and twenty years, not just what it looks like on install day.
If you're weighing board and batten siding for a home in or around Conway, we'll come take a real look at your walls, talk through what your specific exposure needs, and give you a straightforward, no-pressure estimate — no invented urgency, just an honest read on what your house needs.
