What actually makes board and batten siding different to install than standard lap siding?

Board and batten runs vertically instead of overlapping horizontally, so it relies on the panel joints, drainage plane, and flashing underneath the battens to keep water out rather than shedding it downward course by course. That means the prep work behind the panels matters even more than it does with lap siding, since the battens will hide a poor installation just as easily as a good one.

What should I ask a contractor before hiring them for board and batten siding in Bellingham?

Ask what drainage or rainscreen approach they use behind the panels, how they treat panel joints and fastener corrosion resistance, and whether they can explain their process for a specific wall's sun and moisture exposure rather than giving a generic answer. A contractor who's done this work locally should be able to talk through those details without hesitation.

Why does this company only install James Hardie instead of offering vinyl or wood board and batten?

We standardized on James Hardie fiber cement because it doesn't rot, resists the moisture and moss conditions common in this climate, and holds a factory-baked finish instead of needing field paint. Wood and vinyl can both be reasonable products elsewhere, but for board and batten in a wet, coastal-influenced climate we felt the long-term maintenance trade-offs weren't ones we wanted to put on our customers.

What specific James Hardie product do you use for board and batten siding?

We use James Hardie's board and batten fiber cement panels engineered for the HZ5 climate zone, which covers the wet, moisture-heavy conditions typical of the Pacific Northwest, finished with Hardie's factory-applied ColorPlus coating so the color is baked on rather than painted on site.

Does being close to Bellingham Bay actually change how siding should be installed in Fairhaven?

Yes — homes nearer the water deal with more salt-laden air and wind-driven rain, which affects fastener corrosion resistance and how much drainage detailing a wall needs, while shaded inland blocks deal more with prolonged moisture and moss. A crew familiar with the neighborhood accounts for that variation wall by wall instead of treating every house the same.

Board & Batten in a Neighborhood That Notices Detail

Fairhaven has a look to protect. Between the historic commercial core, the craftsman and farmhouse-style homes on the surrounding streets, and the newer infill built to match that character, board and batten siding shows up constantly here — as full facades, as gable accents over lap siding, and as a way to dress up dormers and porch fronts. It's a style that rewards good work and punishes shortcuts, because every batten line is a straight edge your eye follows across the whole wall. When it's installed right, board and batten looks crisp for decades. When it's not, the flaws are impossible to miss from the sidewalk.

We install board and batten siding on Fairhaven homes as part of our regular service area, and we do it exclusively in James Hardie fiber cement. This page covers what that actually means for a home in this part of Bellingham — what the climate does to vertical siding here, what a correct installation involves, and why we don't offer wood, vinyl, or LP SmartSide as alternatives.

What Fairhaven's Climate Does to Vertical Siding

Fairhaven sits close to Bellingham Bay, and that proximity matters more for board and batten than most homeowners expect. Three things work against exterior siding here, and vertical board and batten is more exposed to all three than horizontal lap siding is.

Salt Air

Homes closer to the water pick up salt-laden air, which accelerates corrosion on exposed metal — fasteners, flashing, and trim hardware in particular. On board and batten, the battens themselves create dozens of extra fastening points compared to a lap profile, and every one of those fasteners is a spot where corrosion can start if the wrong hardware was used or if a fastener head is left exposed instead of properly sealed or countersunk.

Driving Rain

Whatcom County gets a lot of rain, and a fair amount of it during winter storms doesn't fall straight down — it's pushed sideways by wind off the water. Vertical siding channels water differently than horizontal siding does. Instead of shedding down and off each overlapping course, water on a board and batten wall runs down the flat panel and can pool or wick at the base of each batten if the gaps, caulking, and drainage plane behind the panel aren't handled correctly.

A Long Moss Season

Bellingham's wet season stretches long, and shaded, tree-covered lots — common on quieter Fairhaven streets — stay damp for months at a time. North-facing walls and anything under tree cover are prone to moss and algae growth. On lap siding that's mostly a cosmetic issue you can wash off. On board and batten, sustained moss growth at the base of battens holds moisture directly against the siding surface, which is exactly the condition that causes long-term problems in any material that isn't built to handle it.

Why Board & Batten Is Less Forgiving Than Lap Siding

All siding profiles need a competent installer, but board and batten has less margin for error. A lap siding installation with a slightly inconsistent nail pattern or a minor caulk gap is often forgiving — water sheds down and off before it finds a way in. Board and batten doesn't have that same built-in redundancy. The battens are functioning as both a design element and a seam cover, and if the seam underneath isn't properly lapped, taped, or drained, the batten is hiding a problem instead of solving one.

This is also a style where the material itself matters more than usual. Board and batten put homeowners' expectations on straight lines and flat panels for years at a time, and any material that swells, warps, cups, or fades unevenly will show it on a vertical panel faster than it would on a narrow lap board.

The Material We Use — And Why We Don't Offer Alternatives

We install James Hardie fiber cement exclusively, including for board and batten applications, and we don't offer wood, vinyl, or LP SmartSide as options. That's a standard we've set for our own work, not a claim that every other product on the market is unusable — plenty of homes in this region are sided in those materials. Here's our honest reasoning, specific to board and batten:

Wood board and batten is the traditional look, and it can be beautiful, but it needs repainting on a regular cycle and is genuinely vulnerable to rot at the batten bases and panel bottoms — exactly the areas where Fairhaven's rain and moss exposure concentrate moisture. Keeping it looking good means an ongoing maintenance commitment most homeowners don't want to sign up for.
Vinyl board and batten profiles exist, but vinyl expands and contracts noticeably with temperature swings, which can telegraph as visible waviness on a large flat panel over time. It's also a thinner, lighter material that doesn't hold up as well under UV exposure and impact as fiber cement does.
LP SmartSide is a wood-strand product with an engineered resin coating, and it performs reasonably well when installation and caulking are maintained perfectly — but it's a wood-based product at its core, meaning cut edges and seams that aren't sealed and re-sealed on schedule are a moisture entry point. In a climate with this much sustained wet weather, that's a maintenance burden we'd rather not put on a homeowner.

James Hardie's fiber cement is cement, sand, and cellulose fiber — it doesn't rot, it isn't attractive to insects, it doesn't warp with moisture the way wood-based products can, and it holds a factory-applied ColorPlus finish that's baked on rather than field-painted, which matters a lot on a profile where color consistency across large flat panels is part of the appeal. Hardie also engineers its products by climate zone (HZ5 for the Pacific Northwest), which accounts for exactly the wet, moss-prone, salt-exposed conditions Fairhaven homes deal with.

Comparing the Options

Material	Moisture & Rot Resistance	Maintenance	Behavior on Large Flat Panels	Typical Lifespan
James Hardie fiber cement	Non-combustible, doesn't rot; engineered for wet climates (HZ5)	Occasional wash; no repainting with ColorPlus finish	Stays flat and straight; factory finish resists fading	Multiple decades with correct install
Wood	Vulnerable to rot, especially at batten bases	Regular repainting/staining and caulk upkeep	Can cup, warp, or check over time	Shorter without diligent upkeep
Vinyl	Doesn't rot, but seams and fasteners are moisture-sensitive	Low, but limited repair options if damaged	Can show waviness with temperature swings	Moderate; UV and impact wear over time
LP SmartSide	Resin-coated wood strand; edges vulnerable if seals fail	Ongoing caulk and touch-up maintenance	Generally stable if maintained on schedule	Moderate, maintenance-dependent

What Correct Board & Batten Installation Actually Involves

The batten is the visible part, but the work that keeps a board and batten wall dry happens underneath it. A correct installation in a climate like this includes:

A properly lapped and sealed weather-resistive barrier behind the panels, with attention paid to every seam and penetration
A drainage gap (rainscreen) where wall conditions call for it, so any moisture that does get behind the panel has somewhere to go instead of sitting against the wall sheathing
Correct panel-to-panel joint treatment — taped, flashed, or lapped per manufacturer spec, not just covered by a batten and hoped for the best
Fasteners placed and set to manufacturer specification, with corrosion-resistant hardware appropriate for a coastal-influenced climate
Proper clearance at the base of the wall and at grade, so battens aren't wicking moisture up from soil, mulch, or standing water
Flashing at windows, doors, and any horizontal trim that interrupts the vertical run, since these are the highest-risk points on any board and batten wall

Skipping any one of these doesn't necessarily cause a visible problem in year one. It shows up in year five or ten, as staining, soft spots, or moss buildup at specific seams — usually in a pattern that traces straight back to where the shortcut was taken.

Our Process for Fairhaven Homes

When we quote a board and batten project in Fairhaven, we walk the exterior first and pay specific attention to sun and wind exposure by wall — a north-facing wall shaded by mature trees and a south wall exposed to bay wind on the same house can need different detailing, even though they'll look identical once the siding's up. We check existing moisture damage before covering anything, confirm the drainage and barrier approach for each wall, and lay out batten spacing to work cleanly around windows, corners, and trim rather than forcing an awkward final piece at the end of a run.

If a home is inside or near Fairhaven's historic district, we're also mindful that some exterior changes in that area can involve design review — we'll flag that early so it's factored into the timeline rather than discovered partway through.

Why Local Experience in Fairhaven Matters

A crew that only installs siding occasionally in this neighborhood is learning its microclimates on your house. Fairhaven isn't uniform — a block near the waterfront deals with more direct wind and salt exposure, while a shaded, tree-lined block a few streets up deals more with sustained moisture and moss. A crew that regularly works this area already knows which walls need extra drainage detailing and which fastener choices hold up, instead of applying a one-size-fits-all approach and hoping the climate cooperates.

Signs Your Current Siding Is Ready for a Look

Visible moss or algae buildup that returns quickly after cleaning, especially at batten bases
Soft, spongy, or discolored spots on wood or wood-based panels
Persistent staining below seams or trim, suggesting water is tracking down from a failed joint
Visible waviness or panel movement on vinyl in direct sun
Peeling, chalking, or fading paint that's outpacing your repainting schedule
Gaps opening up at battens or corner trim over time
