How is board & batten siding actually installed, step by step?

The wall gets a drainable water-resistive barrier and flashing at every window, door, and penetration first, then vertical panels go up with a rainscreen or drainage gap where conditions call for it, and battens are fastened over the joints to a consistent reveal. The finish work — caulking, trim, and touch-up — comes last. Skipping the drainage layer is the most common shortcut that causes problems down the road.

What should I ask a contractor before hiring them for board & batten siding?

Ask whether they include a rainscreen or drainage gap, what fastener type they use given our salt air exposure, and whether they're installing to the manufacturer's published fastening and gapping specs rather than eyeballing it. Also ask what happens if they find rot or sheathing damage once the old siding is off — a clear answer there tells you a lot about how they handle surprises.

Why does your company only install James Hardie and not cedar or LP SmartSide for board & batten?

We standardized on Hardie's fiber cement because it holds its factory-applied finish, doesn't swell or rot from trapped moisture, and comes with a real transferable warranty — all things that matter more on a joint-heavy profile like board & batten. Cedar and wood-based panel products can look great initially but need a maintenance schedule that's tougher to keep up with in a long moss season.

What's the difference between Hardie's standard siding and their HZ product line?

Hardie's HZ formulations are engineered specifically for wetter, colder climates rather than a single national product, which is why we spec HZ5 for board & batten work in this region. It's the same fiber cement technology, tuned for the moisture exposure our walls actually see.

Does Birchwood's location affect how board & batten siding should be installed compared to other parts of Bellingham?

The core installation standards don't change, but exposure does — walls that take direct wind-driven rain need more careful drainage detailing, and shaded, tree-covered walls common on wooded lots in this area stay damp longer, which affects how much attention moss and mildew resistance gets in the finish choice. A crew familiar with this neighborhood accounts for those differences instead of treating every wall the same.

Board & Batten Siding Services in Birchwood

Board & Batten Siding Built for Birchwood

Birchwood homeowners tend to like board & batten for the same reason we do: it's a clean, confident look that suits everything from a modest rambler to a farmhouse-style remodel. The vertical lines read as more custom than flat lap siding, and the pattern hides minor wall irregularities better than most other siding profiles. But in this part of Whatcom County, the look is only half the job. The other half is making sure that siding actually survives the weather it's up against year after year.

We install board & batten siding for Birchwood homes as one piece of a broader Bellingham-area siding practice, which means we're not guessing at what this neighborhood's houses go through. We're accounting for it in the product, the details, and the install.

What Bellingham's Climate Actually Does to Vertical Siding

Board & batten has more seams than a plain lap profile — every batten strip creates a joint where water can find its way behind the cladding if the install isn't right. That matters more here than in a dry climate, for a few specific reasons tied to this region:

Salt air: Being close to the Puget Sound / Bellingham Bay air corridor means airborne salt accelerates corrosion on fasteners, flashing, and any metal trim that isn't rated for it.
Driving rain: Storms here don't just fall straight down — wind-driven rain pushes water sideways into vertical joints and batten edges, which is exactly where a weak installation fails first.
A long moss season: Whatcom County's damp stretch runs long, and shaded, north-facing walls (common on wooded Birchwood lots) stay wet longer between dry spells, giving moss, algae, and mildew more time to take hold on porous or poorly finished materials.

None of this makes board & batten a bad choice. It makes the choice of material and the quality of the install the whole ballgame.

Why This Hits Vertical Siding Harder Than Horizontal

With horizontal lap siding, each course naturally sheds water downward and off the face below it. Board & batten runs the other direction — water traveling down a vertical joint has more distance to travel before it clears the wall, and more opportunity to get pushed sideways by wind before it does. That's why the flashing and gapping details matter more on this profile than almost any other siding style.

Why We Install James Hardie for Board & Batten — and Nothing Else

We standardized on James Hardie fiber cement for every siding job we do, board & batten included, and we don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar. For a vertical siding profile in a marine climate, the reasoning holds even more than usual:

Non-combustible core: Fiber cement doesn't feed a fire the way wood-based panel products can, which matters for insurance and long-term risk regardless of region.
Moisture-stable: Hardie's fiber cement doesn't swell, cup, or rot the way wood-based panels can when a joint takes on water during a wet stretch.
Factory-cured ColorPlus finish: The color and sealant are baked on at the factory under controlled conditions, which holds up far better against driving rain and UV than field-applied paint or a mill-primed surface waiting on a paint job.
Climate-engineered HZ product line: Hardie's HZ5 formulation is engineered for wetter, colder climates like ours, rather than a one-size-fits-all product.
Transferable warranty: A real, honored warranty matters more on a profile with more seams — it's the manufacturer standing behind the material's performance in exactly these conditions.

Cedar board & batten can look beautiful the day it's installed, but it demands a maintenance schedule (staining, sealing, moss treatment) that most homeowners underestimate — and in a long moss season, that schedule gets tighter, not looser. Primed spruce carries similar risk with less rot resistance. Vinyl board & batten is low-maintenance but it's a thin, flexible material that can warp in temperature swings and simply doesn't project the same weight and shadow line that makes this profile look right in the first place. We'd rather tell a Birchwood homeowner that upfront than sell something we don't think holds up.

What a Correct Board & Batten Install Involves

The visible result of good board & batten is simple — straight lines, consistent reveals, tight corners. What makes it actually perform is mostly invisible once the job is done:

Behind the Cladding

A drainable water-resistive barrier (WRB), properly lapped shingle-style, so any water that does get behind the panel has somewhere to go besides your sheathing.
A rainscreen gap or furring where conditions call for it, giving trapped moisture a path to drain and dry instead of sitting against the wall.
Correctly flashed windows, doors, and any wall penetrations — this is where most water intrusion problems actually start, not at the field of the siding.

The Panel and Batten Work

Manufacturer-specified fastener spacing and type — corrosion-resistant fasteners matter more here given the salt air exposure.
Proper gaps at panel butt joints and around trim, caulked and sealed per Hardie's published details, not just butted tight.
Battens installed to cover joints fully with consistent spacing, keeping the reveal even across the whole wall plane.
Correct clearance at the base of the wall and at grade so the bottom edge isn't sitting in standing water or splash-back.

Skip any one of these and the siding can still look right for a season or two. The problems show up later — at the joints, behind trim, and at the base of the wall — which is exactly where they're hardest and most expensive to fix after the fact.

What We See Go Wrong on Older or Rushed Installs

When we're called out to look at board & batten that's failing early, it's rarely the material's fault. The pattern we see most often in this area:

Battens face-nailed directly over unsealed joints, trapping moisture instead of shedding it.
No rainscreen or drainage gap on a wall that gets heavy wind-driven rain, so water has nowhere to go once it's behind the panel.
Standard fasteners used in a salt-air zone, corroding and streaking the finish years before the siding itself is due for attention.
Siding run too close to grade or a deck surface, keeping the bottom courses damp long after a storm passes — a direct invitation for moss and rot.

Our Process for a Birchwood Board & Batten Project

On-site assessment: We look at your home's specific exposure — how much wind-driven rain it takes, how much shade and moisture the walls hold onto, and the condition of the sheathing underneath the existing siding.
Product and detail plan: We spec the Hardie board & batten system, panel width and reveal, color, and the flashing/drainage details specific to your walls.
Prep and tear-off: Removing old siding gives us a chance to inspect and repair any sheathing or framing damage before it gets covered up again — a step that matters a lot more than it sounds like.
WRB, flashing, and drainage installed first: Before a single panel goes up, the water management layer is in and correct.
Panel and batten installation: Installed to Hardie's fastening and gapping specifications, not shortcuts.
Final detailing and walkthrough: Trim, caulking, touch-up, and a walk-through so you know what to expect from the finish over time.

Cost Factors for Board & Batten in Birchwood

Every home is different, but these are the main variables that move the price on a board & batten project in this area:

Factor	Why It Matters
Wall condition underneath	Rot or moisture damage found during tear-off adds repair scope before new siding can go on.
Wall exposure and height	Walls facing prevailing wind-driven rain need more careful drainage detailing; taller walls and multi-story sections add labor and access cost.
Trim and corner complexity	More windows, dormers, and corners mean more flashing and trim work, which adds time regardless of the siding itself.
Panel width and reveal choice	Wider reveals can mean fewer battens and joints; narrower reveals give a different look but more seams to detail correctly.
Color and finish	Factory ColorPlus finishes vary by color line, and some premium finishes cost more than standard options.

Why a Crew That Already Works Birchwood Matters

Whatcom County isn't uniform — a wall that catches heavy wind-driven rain off open exposure behaves differently than a shaded, tree-covered lot that stays damp longer between dry spells. A crew that's already worked in and around Birchwood has a feel for which walls need extra attention to drainage detailing and which don't, without having to relearn that from scratch on your project. That familiarity shows up in fewer surprises during tear-off, a flashing plan that matches how your specific walls actually get hit by weather, and a finished job that's built for the moss season and driving rain this area gets every year — not a generic install dropped into a different climate.

A Quick Homeowner Checklist

Ask whether a rainscreen or drainage gap is included, not assumed.
Confirm the fastener type is rated for coastal/salt-air exposure.
Get the panel reveal and batten spacing specified in writing, not just "standard."
Check that window and door flashing details are part of the scope, not an afterthought.
Ask what happens if rot or damage is found once the old siding comes off.
