Bellingham Why Board & Batten Is Making a Comeback in Bellingham
Board and batten has been showing up on more remodels and new builds around Whatcom County over the past several years — on farmhouses in the Guide Meridian corridor, on craftsman-style infill near Fairhaven, and on modern builds with clean vertical lines overlooking Bellingham Bay. It's a good-looking style. It's also one of the easiest siding styles to get wrong, because the visual simplicity hides a fair amount of technical detail underneath.
This page is about what actually separates a board and batten job that lasts twenty-plus years from one that starts showing rot, streaking, or panel movement within five. We install James Hardie fiber cement exclusively, and board and batten is one of the styles where the difference between a properly engineered system and a improvised one shows up fastest.
What Board & Batten Actually Is
Traditionally, board and batten is wide vertical boards installed with narrower strips (battens) covering the seams between them. It started as a practical barn-building technique — wide boards for coverage, battens to close the gaps as wood shrank and swelled with moisture. That moisture-driven movement is exactly what modern fiber cement systems are designed to control, since fiber cement doesn't shrink and swell the way solid wood does.
There are two common ways to build the look today:
- True board and batten — vertical panel siding with separate batten strips fastened over the seams
- V-groove or reveal panel siding — a single engineered panel milled to look like individual boards, with no true seam underneath
Both can look correct from the curb. They perform very differently over time, which is the part most homeowners never get shown before signing a contract.
Where Board & Batten Installations Go Wrong
Vertical siding has to manage water differently than horizontal lap siding. On a lap system, gravity does most of the work — each course sheds water onto the one below it. On a vertical system, water runs straight down the face of the board and battens, and every seam, fastener, and horizontal transition is a place water can find its way behind the cladding if it's not detailed correctly.
The most common failure points we see on board and batten jobs that weren't built to spec:
- Battens face-nailed directly through both boards and the seam below, pinning the assembly and giving water a direct path along the fastener shank
- No weather-resistant barrier (WRB) or an improperly lapped one behind the panels, so any water that does get past the surface has nowhere to go but into the sheathing
- Missing rainscreen gap, which traps moisture against the back of the panel instead of letting it drain and dry
- Battens and boards run tight to grade, deck ledgers, or roof lines with no clearance or flashing
- Butt joints in long runs that aren't flashed or back-primed, especially in gable ends that take direct weather
None of these mistakes are visible on installation day. They show up two, five, or eight winters later as staining, soft spots at the base of boards, or battens that have started to cup and pull away from their fasteners. By then it's a tear-off, not a touch-up.
The James Hardie Board & Batten System
Hardie builds board and batten as an engineered system rather than a stack of individual boards. Depending on the look a homeowner wants, we typically install one of two approaches:
HardiePanel Vertical Siding with HardieTrim Battens
HardiePanel is a solid fiber cement sheet installed vertically, then true HardieTrim boards are fastened over the seams as battens — real board-and-batten construction, not a printed imitation. Because both the panel and the batten are non-combustible fiber cement engineered to the same moisture and dimensional standards, they move together instead of against each other.
Artisan V-Groove and Board & Batten Panels
For homeowners who want a more refined, tighter-reveal look, Hardie's Artisan line offers pre-finished vertical panels with a factory V-groove or batten profile milled in. These carry a heavier panel and a more precise factory finish, which shows in the shadow lines up close.
In both cases, correct installation means a drainable WRB behind the panel, a rainscreen gap (furring strips or a manufactured drainage mat) so any incidental moisture can drain and the wall can dry, stainless or coated fasteners at the manufacturer's specified pattern, and proper clearance and flashing at every horizontal transition — roof lines, decks, grade, and window and door heads.
Why This Matters More in Whatcom County
Bellingham's climate is genuinely harder on exterior walls than it looks on a sunny July afternoon. Homes near the bay and the county's coastal edges take salt-laden air that accelerates corrosion on the wrong fastener and finish combinations. Driving rain off the Strait pushes water sideways into wall assemblies, not just straight down, which is exactly the condition a rainscreen gap is designed for. And the long gray, wet stretch from fall through spring means anything without a real drying path stays damp for months at a time — which is also why moss and algae get a foothold on siding here faster than in drier climates.
None of that is a reason to avoid board and batten. It's a reason to insist on the moisture-management details — the WRB, the rainscreen gap, the flashing — that a lot of quick installs skip because they're invisible once the siding goes up. Fiber cement itself doesn't rot or feed mold the way wood battens can, but a poorly detailed wall behind any siding material will still hold moisture and eventually cause problems in the sheathing and framing.
Installation Comparison: What Correct Looks Like
| Detail | Common Shortcut | Correct Hardie Installation |
|---|---|---|
| Weather barrier | Housewrap stapled loosely, laps not sealed | Continuous WRB, properly lapped and taped at seams and penetrations |
| Airflow behind siding | Panels fastened tight to sheathing | Rainscreen gap for drainage and drying |
| Fasteners | Standard nails, inconsistent spacing | Corrosion-resistant fasteners at Hardie's specified pattern and embedment |
| Ground clearance | Boards run to grade or pavement | Minimum clearance maintained per manufacturer spec, with flashing |
| Butt joints | Left unflashed, caulk-dependent | Flashed and staggered per manufacturer instructions |
Color and Finish Options
Board and batten's clean vertical lines show color and shadow differently than horizontal lap siding, so finish choice matters more here. Hardie's ColorPlus factory finish is baked on and backed by a longer performance warranty than field-applied paint, and it holds a more consistent tone across large flat panel areas than most contractors can achieve with a paint sprayer on site. For homeowners who want a specific custom color that isn't in the ColorPlus palette, Hardie primed panels can be field-painted, though that shifts some of the long-term color warranty responsibility onto the paint job rather than the factory finish.
What Board & Batten Costs to Do Right
| Cost Factor | Why It Moves the Price |
|---|---|
| Panel system choice | Standard HardiePanel + HardieTrim vs. pre-finished Artisan panels |
| Rainscreen and WRB detailing | Furring strips or drainage mat, taped WRB add labor but are non-negotiable for performance |
| Wall height and complexity | Gables, dormers, and multiple roof intersections increase flashing and cut work |
| Existing wall condition | Sheathing repair or replacement found during tear-off |
| Finish selection | ColorPlus factory finish vs. field-primed and painted |
Because so much of what determines long-term performance is hidden behind the panel, two board and batten quotes that look similar on paper can represent very different installations. It's worth asking what's actually happening behind the siding, not just what brand of board is being used.
Checklist: Vetting a Board & Batten Installer
- Ask specifically whether a rainscreen gap or drainage mat is included, not just a WRB
- Confirm fastener type and spacing match Hardie's published installation instructions
- Ask how butt joints and horizontal transitions (roof lines, decks, window heads) will be flashed
- Confirm ground clearance will meet manufacturer minimums, not just "close enough"
- Ask if the installer is a certified James Hardie contractor and has documentation to show it
- Get the warranty terms in writing — both the manufacturer's product warranty and the installer's workmanship warranty
Maintenance Once It's Installed Correctly
A correctly built Hardie board and batten wall is genuinely low-maintenance for our area — no re-caulking seams every couple of years, no repainting battens that have started to cup. The main maintenance item in Whatcom County is the same one that affects every siding material here: keeping gutters clear so runoff doesn't sheet down the wall face, and an occasional gentle rinse to keep moss and algae from establishing on north-facing or shaded walls where the long wet season gives them the most time to take hold.
