Board & Batten Siding in Columbia, Bellingham, WA

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

Columbia is one of Bellingham's older, close-in neighborhoods, and it shows in the housing stock — a mix of craftsman bungalows, mid-century cottages, and newer infill homes sitting close to Bellingham Bay and the waterfront district. Board and batten siding shows up a lot here, and for good reason: the vertical lines suit both the older cottage-style homes and the newer builds going up on smaller lots. It reads as clean and a little more custom than lap siding, without looking out of place next to a 1920s bungalow.

But board and batten is also one of the less forgiving siding profiles if it's installed wrong. The battens create dozens of extra seams and fastener points compared to a lap pattern, and every one of those is a place water can get behind the cladding if the install isn't done correctly. In a neighborhood this close to the water, that detail matters more than the style choice itself.

What Bellingham Bay Air Does to Vertical Siding

Columbia's location near the waterway means homes here deal with salt-laden air on top of everything else Whatcom County throws at siding: driving rain that comes in sideways off the Sound, long gray stretches where surfaces stay damp for days, and a moss season that runs longer than most homeowners expect. Salt air accelerates corrosion on fasteners and metal flashing, and it's harder on paint finishes and caulk joints than inland exposure. Combine that with sustained damp and you get a setup where any weak point in the siding system — a poorly lapped seam, a batten nailed too tight, a missing flashing detail — turns into a moisture problem faster than it would in a drier climate.

Board and batten's vertical grain also means water runs down the face of the boards and battens continuously during Bellingham's wet months. That's fine when the material and the fastening are matched to the exposure. It's a slow-motion problem when they're not.

Where Board & Batten Fails If It's Cut Corners

• Battens face-nailed directly through both battens and boards into wet, expanding wood — this is a common shortcut that eventually splits boards and opens gaps
• No rainscreen gap behind the panel, trapping moisture against the wall assembly instead of letting it drain and dry
• Butt joints and corners without proper flashing or sealant designed for repeated wet-dry cycling
• Battens spaced or fastened without room for the panel to expand and contract seasonally
• Bottom edge too close to grade, hardscape, or a roofline where splashback keeps it wet

What a Correctly Installed Board & Batten Job Involves

Done right, board and batten is a layered system, not just boards nailed to a wall. On a Columbia home, that system starts with a proper weather-resistive barrier, moves through a drainage gap so water that gets behind the cladding can escape, and finishes with the panels and battens fastened to manufacturer spec — correct nail size, correct spacing, correct penetration into framing or furring, not just into sheathing.

Flashing at every horizontal transition — window heads, roof-to-wall intersections, the bottom termination near grade — has to be integrated with the water-resistive barrier in the right shingle-lap order, not just caulked over afterward. Caulk is a maintenance item, not a waterproofing strategy; a home that depends on caulk staying perfect to stay dry is a home that's one missed re-caulk cycle away from a moisture problem.

The Install Sequence We Follow

1. Tear off old siding and inspect the sheathing and framing underneath for existing rot or moisture damage
2. Repair or replace any compromised sheathing before anything new goes on the wall
3. Install a code-compliant weather-resistive barrier, lapped correctly at every seam
4. Add a rainscreen furring strip system to create a drainage and drying gap behind the siding
5. Flash all penetrations, window and door openings, and horizontal transitions before panels go up
6. Install boards and battens per the manufacturer's fastening schedule, with proper expansion gaps
7. Caulk and finish per spec, then a final walk-through inspection before we call it done

Why We Only Install James Hardie for This Profile

We don't offer board and batten in vinyl, LP SmartSide, primed spruce, or cedar. That's a deliberate standard, not a limitation of what we're capable of installing. Board and batten in particular exposes the weaknesses of those materials because the vertical orientation and extra seam count magnify whatever moisture sensitivity a product already has.

Cedar board and batten looks great new but demands a maintenance schedule most homeowners don't keep up with — regular refinishing, vigilance against moss and mildew, and vulnerability to the same driving rain and damp stretches that define a Bellingham winter. Primed wood products need field-applied topcoats and are exposed at every cut edge unless that edge is sealed perfectly, every time. Vinyl board and batten is low-maintenance but it's a thin, flexible material that shows waviness over time and doesn't hold paint if a homeowner ever wants to change the color. LP SmartSide is an engineered wood product — better than raw wood in some ways, but it's still wood-based, meaning the cut edges and any moisture intrusion point are managed, not eliminated.

James Hardie fiber cement board and batten (HardiePanel or the Artisan lines, with matching batten strips) is dimensionally stable, doesn't swell or rot from moisture the way wood-based products can, and carries a factory-applied ColorPlus finish that's baked on rather than field-applied — meaning the color and the moisture barrier at the panel face are consistent from the first course to the last, and there's no repaint cycle driving the maintenance schedule. It's also non-combustible, which matters more every fire season here.

Comparing Board & Batten Material Options

Material	Moisture Behavior in Wet Climates	Maintenance	Typical Lifespan
James Hardie Fiber Cement	Dimensionally stable; engineered for wet/dry cycling	Occasional wash; no refinishing needed	30+ years, warranty-backed
Cedar	Absorbs moisture; prone to cupping and rot without upkeep	Refinish every 3-5 years	15-25 years with diligent care
Primed Spruce/Wood Composite	Vulnerable at cut edges and joints	Field-applied topcoat, ongoing caulk checks	15-20 years
LP SmartSide	Engineered wood core; edges need sealing diligence	Periodic inspection of seams and cut edges	20-30 years per manufacturer spec
Vinyl	Doesn't rot but can warp/wave; seams flex	Low; occasional wash	20-30 years, fades over time

Our Process on a Columbia Project

Every job starts with an on-site walk of the home, not a phone estimate. We look at how the house sits relative to prevailing wind and rain direction, where grade and hardscape put siding at risk of splashback, and what the current siding and sheathing are telling us about moisture history. In an older Columbia neighborhood, that history matters — a lot of the housing stock here has been re-sided at least once, and what's underneath the current siding is often more telling than what's visible on the surface.

From there we scope the tear-off, any sheathing repair, the rainscreen and flashing package, and the Hardie board and batten install itself, and put it in writing before any work starts. No surprise change orders for things we could have caught during the walk-through.

Keeping Board & Batten Siding in Good Shape

• Rinse siding annually to clear salt residue, pollen, and the start of moss or algae growth
• Keep gutters clear so overflow doesn't run down the wall face and saturate battens
• Trim back vegetation and keep sprinkler heads from spraying directly on the siding
• Walk the exterior once a year and look for cracked caulk joints, especially around windows and at the base
• Address any impact damage or loose battens promptly — small gaps get worse fast in a wet climate

Why Local Experience on This Profile Matters

A crew that's worked board and batten jobs elsewhere in Whatcom County knows what generic installation instructions don't tell you: how tight to run the rainscreen gap given how wet this region actually gets, where flashing tends to get skipped on production jobs, and how a home's specific exposure to wind and rain off the bay should change the detailing. That's the difference between a board and batten job that looks right for five years and one that performs right for thirty.
