Anacortes Board & Batten Siding in Conway, Washington
Conway sits low in the Skagit River delta, close enough to Skagit Bay that salt-laden air is a daily fact of life, and shaded enough by big conifers and river-bottom fog that moss and mildew get a real head start every year. Board and batten siding has always suited this kind of farm and river-valley setting — it's the look on a lot of the older barns, sheds, and farmhouses scattered through this part of Skagit County. But the vertical board-and-batten profile is not automatically the right fit for every material. Get the material or the install wrong here and you'll be fighting moss, panel cupping, and rot at the battens within a few winters. Get it right, and it's one of the most durable, lowest-maintenance vertical siding profiles you can put on a house in this climate.
This page is about board and batten siding specifically for Conway properties — what the local conditions demand from it, what a correct installation looks like, and why we only install it in James Hardie fiber cement rather than wood, vinyl, or other fiber cement brands.
Why Conway's Climate Is Hard on Vertical Siding
Salt air off the bay
Airborne salt from Skagit Bay and the broader Puget Sound corridor accelerates corrosion on exposed fasteners and speeds up the breakdown of lower-grade paint films. On board and batten profiles, the battens themselves — the narrow strips covering each seam — carry a disproportionate share of face-nailing, so fastener quality and finish integrity matter more here than on a flat lap siding job.
Driving rain and wind-driven moisture
Storms moving up the valley off the water don't just fall straight down — wind pushes rain sideways into wall assemblies. Board and batten relies on the seams between boards being genuinely weather-tight, not just visually clean. A batten that looks fine from the ground can still be letting water track behind it if the underlying panel joint and flashing weren't detailed correctly.
A long moss season
Between river valley humidity, tree cover, and short winter daylight, Conway gets an extended window every year where siding surfaces stay damp far longer than they would in a drier part of the state. Wood-based products absorb that moisture and feed moss and mildew growth at the surface. Fiber cement doesn't give organic growth the same foothold, but even fiber cement needs the right factory finish and installation clearances to actually resist it long-term.
What a Correct Board & Batten Installation Requires
Board and batten is a simple-looking profile, but it hides a lot of the details that decide whether it lasts 10 years or 40. On a Conway home, we pay particular attention to:
- Proper rainscreen or drainage gap behind the panels, so any moisture that does get past the battens has somewhere to go besides your sheathing
- Correct batten spacing and fastening pattern — over-driven or under-driven nails both create failure points
- Flashing and kickout details at every roof-to-wall intersection, window head, and horizontal trim break
- Factory-finished panel edges rather than field-cut edges left exposed to weather
- Consistent, code-minimum clearance from grade, decks, and patios so splash-back moisture isn't hitting the bottom course year-round
- Sealant only where the manufacturer's install guide actually calls for it — over-caulking traps moisture as often as it keeps it out
Skip any one of these and the siding can look correct for a year or two while moisture works behind it unseen.
Why We Only Install James Hardie for This Profile
Board and batten is available in wood, vinyl, engineered wood, and several fiber cement brands. We install James Hardie exclusively, and for this particular profile the reasons are pretty concrete:
Non-combustible core
Hardie's fiber cement composition doesn't support flame spread the way wood-based battens and boards can. That matters throughout Skagit County, where dry-season wildfire risk is a real consideration even this close to the water.
Factory-applied ColorPlus finish
Rather than field-painting boards and battens after install — which is where a lot of vertical siding jobs cut corners — Hardie's ColorPlus finish is baked on at the factory under controlled conditions, with a finish warranty that follows it. In a climate that keeps siding damp for extended stretches, a factory finish resists fading and moss staining meaningfully longer than field-applied paint on wood or engineered wood substrates.
HZ5 engineering for the Pacific Northwest
Hardie manufactures climate-specific product lines, and the HZ5 formulation is engineered for the freeze-thaw and moisture cycling typical of our region. That's a meaningful difference from a one-size-fits-all siding product.
Dimensional stability
Wood and engineered-wood battens expand, contract, and can cup or bow as they take on and release moisture through a wet Conway winter. Fiber cement holds its shape far better over time, which keeps seams tight and battens flat instead of curling at the edges.
Board & Batten Material Comparison
| Material | Moisture Behavior | Finish | Typical Long-Term Concern in Conway |
|---|---|---|---|
| James Hardie fiber cement | Stable, doesn't swell or rot | Factory ColorPlus, warrantied | Correct install and flashing detail still required |
| Cedar or primed wood | Absorbs moisture, feeds moss | Field-applied, needs recoating | Rot at battens and panel seams over time |
| Vinyl board & batten | Doesn't rot but can warp/crack in temperature swings | Color molded-in, fades over time | Loses fit and rigidity, seams can gap |
| Engineered wood (LP-type) | Better than raw wood but still moisture-sensitive at cut edges | Factory-treated, edge-sensitive | Edge swelling if cuts aren't sealed correctly |
Our Process for Conway Board & Batten Projects
1. On-site assessment
We look at the specific exposure of each wall — which faces take the most wind-driven rain off the valley, which stay shaded and damp longest, where the existing siding is already showing moss or fastener staining — before recommending anything.
2. Moisture and sheathing check
Before any new siding goes on, we check what's happening underneath the old material. Board and batten in particular can hide long-term moisture damage behind intact-looking battens, so this step isn't optional.
3. Drainage plane and flashing installation
We install a proper water-resistive barrier and drainage gap, then detail flashing at every penetration and transition before the first panel goes up.
4. Hardie panel and batten installation to spec
Fastening pattern, batten spacing, and clearances are installed to Hardie's published specifications for our climate zone — not shortcut for speed.
5. Final walk-through
We go over the finished work with the homeowner, including what routine maintenance (if any) to expect and how the warranty coverage works.
Why Local Experience in Conway Matters
Conway isn't a large town, and it doesn't get the volume of siding work that a bigger Skagit County city sees. That's exactly why local, hands-on experience with this specific stretch of the delta matters: knowing which walls on a river-valley property take the worst of the weather, understanding how close-set tree cover changes drying time after a storm, and having already worked through the flashing and clearance details that this environment demands. A crew that treats every job like a generic install, regardless of where the house sits, is more likely to miss the details that matter here.
Maintenance Expectations After Installation
One of the practical advantages of correctly installed Hardie board and batten in this climate is how little ongoing maintenance it asks for compared to wood alternatives:
- No repainting cycle — the factory finish is designed to hold color for years, not seasons
- Occasional gentle rinsing to clear moss spores or road/salt film before they set in
- Periodic visual check of caulking at trim joints, since sealant is the one component that does age faster than the siding itself
- Prompt attention to any impact damage so the drainage plane behind it stays intact
Cost Factors to Expect
Every property is different, but the main variables that affect board and batten project cost in Conway are generally the same: the condition of the existing wall assembly and whether repairs are needed before new siding goes on, the total wall area and number of corners/penetrations to flash, the trim and batten detailing chosen, and site access for a rural or river-valley lot. We'll walk through all of this with you directly rather than quoting a number that doesn't reflect your actual home.
