How is installing board and batten siding different from a standard lap siding job?

Board and batten uses vertical panels covered by narrow battens at each seam, which means more vertical joints, more fasteners, and more flashing details than a horizontal lap profile. It also requires precise batten spacing and a drainage gap behind the panel so any moisture that gets past the surface can escape instead of sitting against the wall. Getting this wrong shows up later as staining or soft spots at the seams, not immediately.

What should I ask a contractor before hiring them for board and batten work in Skagit County?

Ask what fastener type they use given the salt air near Skagit Bay, whether they install a drainage gap or rainscreen behind the panels, and how they handle flashing at windows and rooflines. Also ask whether they've worked in this specific area before, since low-lying, moisture-heavy sites need different handling than drier inland lots. A contractor who can't answer specifically hasn't thought through the climate.

Why don't you install vinyl or LP SmartSide board and batten instead of offering more options?

We standardized on one fiber cement manufacturer so every crew installs to one proven spec, fastening schedule, and warranty rather than switching methods between product lines. Vinyl board and batten flexes and can look uneven on a style that depends on crisp, flat lines, and wood-based products are more vulnerable to moisture at the many seams this style creates. It's a professional standard we hold to, not a claim that other products can't be installed properly by someone else.

What is the HZ5 product line and why does it matter for a Conway home?

James Hardie engineers its siding by climate zone, and HZ5 is the line formulated for wetter, moisture-heavy regions like Western Washington rather than the hot, humid engineering used in other parts of the country. For a home exposed to salt air and driving rain near Skagit Bay, that climate-specific engineering affects how the product holds up at the seams and fastener points over time. It's one of the reasons we don't treat all fiber cement products as interchangeable.

Does Conway's location near Skagit Bay change how you approach a siding project there?

Yes — the salt air pushes us toward corrosion-resistant fasteners and trim hardware we might not prioritize as heavily further inland, and the open, low-lying terrain around Conway means wind-driven rain hits walls harder than in more sheltered parts of the county. We also expect more shaded, moss-prone sections near farmland and tree lines, which factors into finish choice and maintenance guidance we give homeowners. Local site conditions like these are part of every assessment we do here.

Conway Board & Batten Siding: Built for Skagit County's Climate

Board & Batten in Conway: A Style That Has to Earn Its Keep

Board and batten has a long history in the Skagit Valley for a simple reason: it looks right on the kind of homes people build here. Conway sits in the low, flat farmland near the Skagit River delta, close enough to Skagit Bay and Puget Sound that salt-laden air is a fact of life, not an occasional visitor. The wide vertical boards and narrow battens of this siding style read as farmhouse, craftsman, or barn-inspired architecture — a look that fits the agricultural setting around Conway far better than a flat, uniform lap pattern would.

But board and batten is also a style that punishes cheap materials and sloppy installation faster than most. Every batten strip is a seam. Every seam is a place water can find its way in if the product or the workmanship isn't right. On a home near the delta, with wind off the bay and a rainy season that runs most of the year, those seams get tested constantly. This page is about what it actually takes to do board and batten correctly on a Conway home, and why we only do it in one material.

What Skagit County's Climate Does to Vertical Siding

Conway's location puts it at the intersection of a few climate stresses that matter specifically for board and batten construction.

Salt Air and Fasteners

Proximity to Skagit Bay means airborne salt is a slow, steady corrosive force on anything metal. Board and batten siding uses more exposed fasteners and more trim pieces than plain lap siding — every batten strip needs to be fastened, and those fastener heads are often more visible than on a horizontal lap job. Standard fasteners left exposed to salt air will streak, rust, and eventually fail years before the siding itself would need replacing.

Wind-Driven Rain

Western Washington's rain doesn't just fall — a good part of the year it comes sideways, especially in open, low-lying areas like the land around Conway with little to break the wind. Vertical board and batten has more vertical joints for wind-driven rain to test than a lapped horizontal profile does. If those joints aren't flashed and gapped correctly, water gets pushed up and behind the boards instead of running down and off them.

A Long Moss Season

Shaded sections of a home, north-facing walls, and anything near tree cover or irrigation ditches in this farming area will grow moss and algae for a good chunk of the year. Moss holds moisture against the siding surface long after a storm has passed. On an untreated or poorly finished product, that constant damp contact is exactly the condition that starts rot, delamination, or paint failure.

Why We Only Install Board & Batten in James Hardie Fiber Cement

Board and batten is available in wood, engineered wood (LP SmartSide), vinyl, and fiber cement. We've made a standing decision to install it only in James Hardie fiber cement, and on a climate like Conway's, the reasoning holds up.

Primed spruce and cedar board and batten are real wood, and real wood swells and shrinks with moisture. Every one of those battens is a joint where two pieces of wood meet, and wood movement at a joint is where caulk failure and rot get started — especially with the volume of rain this area sees. Cedar looks good freshly installed, but it needs ongoing refinishing to keep performing, and once moisture gets behind a batten in a wet climate, wood doesn't forgive that the way fiber cement does.

LP SmartSide is an engineered wood product — strand board with a resin-saturated overlay. It holds up better than raw wood, but it's still wood-based at its core, which means cut edges and any breach in the factory coating are vulnerable to moisture intake. Cemplank and Allura are fiber cement competitors to Hardie, and while the category is sound, we standardized on one manufacturer so our crews install to one spec, one fastening schedule, and one finish warranty every time — no guessing between product lines.

Vinyl board and batten is the cheapest option and the easiest to spot from the street. It's a thin, flexible panel that's screwed or nailed loosely to allow for expansion, and on a style that depends on crisp, flat vertical lines, that flex reads as exactly what it is. Vinyl also becomes brittle in cold snaps and can warp against a dark, sun-exposed wall — not a common problem in Conway's cooler climate, but the flex and the plastic look remain.

James Hardie fiber cement is cement, sand, and cellulose fiber. It doesn't swell, it doesn't rot, and it's non-combustible. Hardie's ColorPlus factory finish is baked on under controlled conditions with a UV-cured, mold- and mildew-resistant topcoat — a real advantage in a place with a moss season this long. Hardie also engineers its products by climate zone; homes in Western Washington fall under Hardie's HZ5 line, formulated for wetter, more moisture-exposed regions rather than the hot, humid product engineering used elsewhere in the country.

Material Comparison for Board & Batten in Conway's Climate

Material	Moisture Behavior	Fastener/Corrosion Concern	Maintenance
James Hardie fiber cement	Does not swell or rot; engineered for wet climates (HZ5)	Low, if corrosion-resistant fasteners are used	Occasional wash; factory finish holds color
Cedar / primed spruce	Swells, shrinks, and can rot at battens over time	Moderate — wood movement stresses fastener holes	Regular refinishing/repainting needed
LP SmartSide	Better than raw wood but vulnerable at cut edges	Moderate	Periodic inspection of edges and seams
Vinyl board & batten	Doesn't rot, but flexes and can look uneven	Low	Low, but style/appearance limitations

What a Correct Board & Batten Installation Actually Involves

Board and batten is less forgiving of shortcuts than lap siding, and in a climate like this one, the details matter more than the material choice alone.

Ground clearance of at least six inches between the bottom of the siding and grade, more where soil sits wet or splashback from rain is likely
A drainage gap or rainscreen behind the panel so any moisture that does get past the surface can drain and dry instead of sitting against the wall sheathing
Correct batten spacing and fastening pattern per manufacturer specification — not eyeballed, since spacing affects both looks and water management
Stainless steel or otherwise corrosion-resistant fasteners, especially important this close to Skagit Bay's salt air
Proper flashing and sealant at every window, door, and roof intersection, plus kick-out flashing wherever a roofline meets a wall
Caulking only at manufacturer-specified joints — over-caulking a fiber cement joint can trap moisture instead of shedding it

Any one of these done wrong won't necessarily show up in year one. It shows up in year five or six, as staining, soft spots, or paint failure at the seams — right when a homeowner assumes the siding should still look new.

Our Process on a Conway Board & Batten Project

On-site assessment. We look at sun and shade exposure, wind direction relative to the bay, drainage around the foundation, and the condition of the existing siding and sheathing.
Removal and inspection. Old siding comes off and we check the sheathing and framing underneath for any moisture damage before anything new goes up — this step matters more in a wet climate than almost anywhere else.
Weather barrier and drainage plane. A correctly lapped weather-resistive barrier and drainage gap go in before any siding, giving water a way out if it ever gets behind the panels.
Installation to Hardie's HZ5 specification. Panels and battens go up with the correct fastening pattern, spacing, and clearances, with flashing integrated at every penetration as we go — not added afterward.
Trim, caulking, and touch-up. Factory-finished ColorPlus panels need touch-up paint matched to the finish, applied only where the manufacturer allows it, to preserve the warranty.
Final walkthrough and cleanup. We walk the job with the homeowner before we call it done.

Cost Factors for Board & Batten Siding in This Area

Factor	Why It Matters in Conway
Home size and wall complexity	More corners, gables, and dormers mean more batten cuts and flashing details
Existing siding removal	Older wood siding on delta-area homes sometimes hides moisture damage that adds sheathing repair
Trim and window count	Each opening needs correct flashing integration, which adds labor time
Site access	Rural and low-lying lots can have soft ground or limited equipment access, affecting scheduling
Finish and color	ColorPlus factory colors avoid on-site painting costs but come at a different price point than field-painted trim

We don't quote a job without seeing it. Anyone offering a firm number over the phone for board and batten work is skipping steps that matter on a house in this climate.

Living With Board & Batten Through a Long Moss Season

Even a correctly installed fiber cement job benefits from a little seasonal attention, especially on shaded walls or anything near tree cover or ditches common around Conway's farmland.

Rinse moss and algae off with a garden hose and soft brush — never a pressure washer aimed directly at the siding or battens
Keep gutters clear so overflow doesn't run down the wall and feed moss growth at the top courses
Trim back vegetation and clear debris that keeps a wall shaded and damp longer than it needs to be
Check caulking at trim and penetrations once a year and have any cracked or missing sealant redone promptly

Why a Crew That Already Works Conway Makes a Difference

Board and batten on a home this close to the water isn't the same job as the same siding style twenty miles inland. A crew that already works Conway and the surrounding Skagit County lowlands knows to plan for salt air corrosion on fasteners without being told, knows how wind off the bay behaves against an open wall, and has already seen what a long moss season does to a wall that wasn't detailed correctly the first time. That local pattern recognition is what keeps a board and batten installation from becoming a callback in a few years.
