How is board and batten different from other Hardie siding styles like lap siding?

Board and batten uses vertical panels with battens covering the seams, giving a more linear, farmhouse-style look, while lap siding uses horizontal overlapping boards. Both are available in James Hardie fiber cement, and the choice usually comes down to the architectural style of the home rather than performance, since both hold up well when installed correctly. Board and batten does have more vertical seams to detail, so installation precision matters slightly more with this style.

What questions should I ask a contractor before hiring them for siding work in Whatcom County?

Ask what siding material they install and why, whether they're a certified or preferred installer for that manufacturer, and how they handle flashing and drainage detailing specifically — not just panel installation. Ask for a written scope of work rather than a one-line estimate, and ask how they'd approach your specific wall assembly given its exposure. A contractor who can answer these in detail without hedging is usually one who's done the work repeatedly in this climate.

Does James Hardie board and batten siding come pre-finished, or does it need to be painted on-site?

James Hardie's ColorPlus panels come with a factory-applied finish baked on before installation, so there's no on-site painting required and the color is backed by its own finish warranty. This is different from primed wood or spruce board and batten, which needs field painting after installation and again on a regular repainting cycle afterward. Factory finishing is one of the main reasons Hardie holds up better than field-painted materials in a wet climate.

Is board and batten siding a good fit for older homes in Marietta, or mainly new construction?

Board and batten works well on both — it's a common re-siding choice for older homes in this area because it can update the exterior significantly while still suiting the region's traditional farmhouse and craftsman styles. The main consideration on an older home is the condition of the existing sheathing underneath, which needs to be checked and repaired if necessary before new siding goes on. That inspection step matters more on an older home than a new build.

Why does exposure to Bellingham Bay matter more for siding choice than being a few miles inland in Ferndale?

Proximity to open water means more direct wind-driven rain, more airborne salt affecting fasteners and finishes, and often more shade and dampness that encourages moss growth. Homes a few miles inland in Ferndale still deal with the region's wet climate but usually see less of the combined salt-and-wind exposure that coastal properties near Marietta face. That's why we evaluate each property's specific exposure rather than treating every Ferndale-area home the same.

Board & Batten Siding for Marietta Homes

Marietta sits low and close to the water on the edge of Bellingham Bay, just outside Ferndale proper, and that location shapes everything about how siding performs there. Board and batten is one of the most requested looks in this part of Whatcom County — the vertical lines read as classic Pacific Northwest farmhouse or craftsman, and they suit the mix of older cottages and newer builds you find around Marietta. But the look is only half the job. The material underneath the battens has to survive a marine environment that punishes anything less than a properly engineered product, and that's where a lot of board and batten installs in this area go wrong long before the paint fades.

This page covers what board and batten siding needs to hold up specifically in Marietta, what a correct installation actually involves, and why we install it in James Hardie fiber cement only — no vinyl board and batten panels, no LP SmartSide, no primed spruce or cedar boards, ever.

Why Marietta's Climate Is Hard on Siding

Whatcom County's coastal exposure isn't subtle. Homes near Bellingham Bay deal with a combination of stressors that inland Ferndale properties see less of:

Salt air: airborne salt off the bay accelerates corrosion on fasteners, hardware, and any metal trim, and it degrades cheap coatings faster than a dry-climate paint job ever would.
Driving rain: wind off the water pushes rain sideways into vertical seams and batten joints — exactly the joints that board and batten siding depends on to stay sealed.
A long moss and algae season: the Pacific Northwest's wet, mild winters and shaded lots let moss and algae take hold on siding that stays damp for weeks at a stretch, especially on north- and west-facing walls closest to the water.
Persistent humidity: even without rain falling, the ambient moisture in this area keeps siding damp longer than it would be almost anywhere inland, which matters enormously for how wood-based products behave over time.

None of this is unique to Marietta — it's the reality for most of coastal Whatcom County — but Marietta's proximity to open water puts it toward the harder end of that spectrum for local homes, which is exactly why the choice of siding material matters more here than it would a few miles inland.

What Correct Board & Batten Installation Involves

Board and batten is a vertical siding system: wide base panels installed first, then narrower battens fastened over the seams between them. It looks simple, but the seams are also the system's biggest vulnerability, and how they're built determines whether the wall stays dry for decades or starts trapping moisture within a few winters.

The details that actually matter

Drainage plane behind the panels: a proper weather-resistive barrier and rain screen gap let any moisture that does get past the battens drain and dry out instead of sitting against the wall sheathing.
Fastener placement and spacing: panels and battens need to be fastened per the manufacturer's engineering — not "close enough" — so seams stay tight under wind load and don't work loose over time.
Batten overlap and caulking strategy: battens need to cover the panel seam fully with the right reveal, and any sealant used has to be compatible with the siding material and rated for exterior UV and moisture exposure.
Flashing at every penetration: windows, doors, hose bibs, light fixtures, and roof-to-wall transitions all need flashing detailed correctly before a single panel goes up — this is where most water intrusion problems actually originate, not the field of the siding itself.
Clearance at grade and hard surfaces: siding installed too close to soil, decks, or patios wicks moisture up from below regardless of how good the material is.

Get these details right and board and batten siding is genuinely one of the most durable, low-maintenance exterior looks available. Get them wrong, and the seams that make the style distinctive become the exact places water finds its way in.

Why We Install James Hardie — Not Vinyl, LP, or Cedar Board and Batten

Board and batten is sold in several materials, and we get asked regularly why we won't install some of them. Here's the honest breakdown.

Vinyl board and batten

Vinyl is affordable and low-maintenance in the sense that it doesn't need painting, but it's a thin plastic product that expands and contracts significantly with temperature swings, which stresses the very seams that hold this style together. In driving rain off the bay, vinyl's overlapping panel design relies on gravity and fit rather than a sealed system, and impact damage from storm debris cracks it rather than dents it. It also doesn't hold up structurally the way a fiber cement panel does — it's a cladding, not a wall component.

LP SmartSide and other engineered wood

Engineered wood products use treated wood strand technology that resists moisture reasonably well when the factory coating stays intact, but the entire system depends on that coating and on caulked seams never failing. In a climate with weeks of sustained dampness and moss growth, any breach in the coating — a scratch, a missed caulk line, a fastener that backs out — lets moisture into a wood-based core, and wood-based cores swell and delaminate once water gets in. We'd rather not install a product whose long-term performance hinges on a factory finish never being compromised in a marine environment.

Primed spruce and cedar boards

Real wood board and batten has genuine appeal, and cedar in particular has a long history in this region. But solid wood is organic material in a climate that stays wet for a large part of the year — it needs regular repainting or restaining, it's a direct food source for the moss and algae that thrive here, and it moves seasonally in ways that stress fasteners and seams. It can look excellent for years with diligent upkeep, but it asks a lot of a homeowner who wants exterior siding to be something they don't think about.

Why James Hardie fiber cement

James Hardie board and batten panels are fiber cement — sand, cement, and cellulose fiber — which means they don't absorb water the way wood-based products do, don't expand and contract with humidity the way vinyl does, and are non-combustible. Hardie's ColorPlus factory finish is baked on and warranted separately from the substrate, so the color and the water resistance aren't riding on field-applied paint holding up through a Whatcom County winter. Hardie also engineers its siding by climate zone rather than shipping one product everywhere — the formulation sold in wet, humid regions like ours is built for exactly the moisture exposure Marietta homes deal with. That combination is why it's the only board and batten material we put on a house.

Comparing the Options

Material	Moisture behavior in a marine climate	Maintenance	Longevity
James Hardie fiber cement	Doesn't absorb or swell; factory finish resists moisture at the surface	Occasional wash; repaint on a much longer cycle if ever needed	Decades, backed by a strong transferable warranty
Vinyl	Doesn't absorb, but seams and panel fit rely on gravity, not sealing	Low, but cracks under impact and can't be spot-repaired invisibly	Variable; degrades faster in constant salt and UV exposure
LP SmartSide / engineered wood	Vulnerable once factory coating is breached; wood-strand core swells	Coating and caulk lines need regular inspection	Depends heavily on installation quality and coating integrity over time
Cedar / primed spruce	Absorbs moisture readily; prone to moss growth and rot without upkeep	Regular repainting/staining; sealant renewal	Shorter without diligent, ongoing maintenance

Our Process for a Marietta Board & Batten Job

On-site assessment: we walk the exterior, check the existing wall assembly and sheathing condition, and note anything specific to the lot — tree cover, wind exposure, proximity to water — that affects the install.
Detailed estimate: a written scope covering panel and batten quantities, trim, flashing work, and the drainage plane approach, with no vague allowances.
Prep and moisture check: old siding removal, sheathing repair if needed, and a check for any hidden water damage before new material goes up — this step is non-negotiable in a climate this wet.
Weather-resistive barrier and rain screen installation: the drainage system goes in before any panel touches the wall.
Panel and batten installation: fastened to Hardie's specifications, with flashing detailed at every window, door, and penetration as we go — not patched in afterward.
Final walkthrough: we review the finished work with the homeowner and cover basic care going forward.

What Affects the Cost

Total wall area and the amount of trim, corners, and penetrations to detail
Condition of the existing sheathing and whether repair is needed before siding goes on
Wall height and accessibility, including any second-story or hard-to-reach sections
Color and finish selection within the Hardie ColorPlus lineup
Scope of flashing and drainage work required by the specific wall assembly

Living With Board and Batten Near the Water

Even the right material benefits from basic upkeep, and homeowners near Marietta's shoreline should expect a slightly different maintenance rhythm than someone siding a house further inland.

Rinse siding periodically, especially shaded north- and west-facing walls, to keep moss and algae from establishing before it becomes a scrubbing job
Keep gutters clear so overflow doesn't run down the wall and concentrate moisture at specific panel seams
Trim back vegetation and tree cover that keeps a wall section shaded and damp longer than the rest of the house
Have caulking at trim and penetrations checked every few years, since sealant is the one component in the whole system that does eventually need renewal
Watch for any fastener corrosion or staining near the coast, where salt air is hardest on exposed metal

Why Hire a Crew That Already Works Marietta

Installation quality is what separates a board and batten job that lasts decades from one that needs attention in five years, and that quality shows up in details a homeowner often can't evaluate from a written bid — flashing sequencing, fastener schedules, rain screen execution. A crew that already works houses in Marietta and along the rest of the Ferndale coastline has already worked out how to detail a wall assembly for this specific exposure, not a generic climate zone. That local repetition is what keeps callbacks low and keeps siding performing the way it's supposed to through another wet Whatcom County winter.
