Ferndale Exterior Board & Batten Siding for Lynden Homes
Lynden sits inland from the coast, but the exterior work here still has to answer to the same marine weather that shapes every job we run across Whatcom County. We're based in the Ferndale area, not commuting in from out of the region, so a Lynden board and batten job isn't a one-off bid for us — it's the same rain, the same salt-laden air, and the same moss pressure we build for on our own local streets. This page is specifically about board and batten siding: what it is, what it needs to hold up in this climate, and how we install it. If you're weighing board and batten against a standard horizontal lap profile for a Lynden home, this is the detail that matters before you sign anything.
Board and batten has become a popular choice on both older farmhouse-style homes and newer builds going up on former agricultural land around Lynden, because it reads as a clean, vertical, slightly more modern or barn-inspired look than traditional lap siding. That look is only worth having if the installation underneath it is done right. Vertical siding manages water differently than horizontal lap siding, and getting that wrong in a climate this wet causes problems faster than it would somewhere drier.
What Board & Batten Siding Actually Is
Board and batten is a vertical siding profile: wide flat panels or boards run vertically up the wall, with narrower strips — the battens — installed over the seams between them. The result is a rhythm of wide-flat, narrow-raised, wide-flat down the face of the house, instead of the stacked horizontal lines of lap siding. It can be built two ways: true board-on-board, where individual vertical boards are installed with a batten covering each seam, or as a panel system, where a wider sheet good is installed and vertical battens are added over the seams (and sometimes at a regular interval across the field for a consistent look even where there's no actual seam underneath).
Panel Systems vs. True Board-on-Board
The panel approach is what most fiber cement board and batten installations actually are, and it's what we install. A full-size vertical panel goes up first, battens go over the seams and at consistent intervals, and the wall ends up with far fewer total joints than a true board-on-board wall built from narrow individual boards. Fewer joints means fewer places for water to find a way in, which is exactly what you want in a climate where wind-driven rain is a routine, not an occasional, condition. True board-on-board can look slightly more traditional up close, but every added seam is another spot that depends on flashing and fastening detail staying correct for decades.
What Lynden's Climate Demands From a Vertical Siding System
Salt Air, Even This Far Inland
Lynden is set back from the immediate shoreline, and people sometimes assume that puts it out of reach of salt exposure. It doesn't. Marine air moves across this whole part of Whatcom County, and over years it works on fasteners, flashing, and any lower-grade trim hardware. On a vertical siding system with a lot of exposed fastener heads along the battens, using the right fastener material and spacing matters more than it would on a wall with fewer penetrations.
Driving Rain and Vertical Seams
Rain here doesn't fall straight down for most of the wet season — wind pushes it sideways into whatever gap or seam it can find. On a horizontal lap wall, gravity is doing some of the water-shedding work by default. On a vertical board and batten wall, that's not automatically true: water can run down a seam and get pushed sideways under wind pressure just as easily as it runs down the face. That's why the water-resistive barrier and flashing detail behind the panels matters even more on a vertical profile than it does on standard lap siding, not less.
A Moss Season That Runs Most of the Year
Mild temperatures, consistent moisture, and plenty of shaded and tree-lined lots around Lynden add up to a moss and mildew season that's active across most of the calendar. Board and batten's raised battens create more surface texture and more shadow lines than a flat lap wall, which can hold moisture a little longer in shaded spots if the finish and installation aren't done right. It's a manageable factor, not a reason to avoid the style — but it's one more reason the finish and the gap details behind each batten need to be correct from day one.
Why We Install This Only in James Hardie Fiber Cement
Board and batten is available in vinyl, engineered wood, and fiber cement, and it's a fair question why we only offer one of those for this profile. Vertical siding concentrates more seams, more fastener penetrations, and more exposed edges per square foot than lap siding does in some layouts, which makes the underlying material's tolerance for moisture and movement more important, not less.
| Material | Common trade-off in board and batten form |
|---|---|
| Vinyl board and batten | Panels expand and contract more visibly in a vertical run; can bow or loosen at fastener slots over time |
| Engineered wood (e.g. LP SmartSide) | Wood-strand core is more moisture-sensitive at cut edges and batten fastener points than fiber cement |
| Primed spruce or cedar board-on-board | Needs ongoing paint and seam maintenance; more total joints than a panel system means more upkeep |
| James Hardie fiber cement | Inorganic core resists swelling at cut edges and fastener points; ColorPlus factory finish holds up without field repainting |
James Hardie's fiber cement panels give us a non-combustible, dimensionally stable board underneath the battens, with the factory-applied ColorPlus finish carrying the color instead of a field-applied coat that has to be maintained on a schedule. The HZ5 formulation is built for regions with sustained moisture exposure and freeze-thaw cycling, which is a closer match to this part of Whatcom County than a general-purpose product line. We don't install vinyl, LP SmartSide, Cemplank, Allura, primed spruce, or cedar in any profile, board and batten included — it's a professional standard we've settled on, not a sales pitch.
What a Correct Board & Batten Installation Involves
Water-Resistive Barrier and Drainage Plane
Everything starts underneath the panels: a continuous water-resistive barrier, correctly lapped and taped, with flashing integrated at every window, door, and roof-to-wall transition before a single panel goes up. On a lot of Lynden re-sides, we prefer to add a rainscreen gap behind the panels — a thin vertical furring space that lets any water that does get past the cladding drain and dry out instead of sitting against the sheathing. That gap matters more on a vertical profile than a horizontal one, because it gives water a clear downward path instead of letting it pool at a seam.
Panel Spacing, Fastening, and Batten Placement
Panels need to be hung plumb with consistent gaps sized to Hardie's published specification, not tight to each other, so the material has room to move seasonally without binding. Fasteners go in at the manufacturer's specified pattern and depth — over- or under-driven fasteners are one of the more common places we find problems on board and batten walls that were installed by a crew unfamiliar with the profile. Battens go on last, sized and spaced to actually land over the panel seams and on a consistent layout across the wall, not just wherever they happen to fit.
Corners, Trim, and Transitions
Outside corners, window and door trim, and the transition where board and batten meets a soffit or a different siding profile are where a lot of vertical siding installs go wrong. Every one of those needs its own flashing and clearance detail, and on a mixed-material Lynden home — say, board and batten as an accent alongside a lap-sided main wall — the transition between the two profiles needs the same careful flashing as any other wall penetration.
- Continuous water-resistive barrier installed and taped before any panel goes up
- Flashing integrated at every window, door, and roof-to-wall intersection
- Rainscreen or furring gap considered behind the panels, especially on shaded or moisture-prone walls
- Panel gaps and fastener pattern matched to the manufacturer's published spec, not eyeballed
- Battens plumb, consistently spaced, and actually landing over seams
- Outside corners and trim transitions flashed individually, not caulked over as an afterthought
Our Process for a Lynden Board & Batten Project
Inspection and Estimate
We start by actually looking at the house: current siding condition, any sign of trapped moisture or sheathing damage under the existing cladding, and how sun, shade, and wind exposure differ across each wall. That's what shapes the estimate and the plan, not a flat per-square-foot number applied without seeing the house.
Prep and Tear-Off
On a re-side, old siding comes off and the sheathing gets inspected before anything new goes up. Any rot or moisture damage found at this stage gets addressed before we cover it back up — covering a known problem with new siding just delays it and makes it more expensive to fix later.
Installation and Finish
Barrier, flashing, panels, and battens go up in that order, following the spacing and fastening detail above. We do a full walkthrough at the end so you can see the finished work and ask questions before we consider the job done, not just a drive-by handoff.
Cost Factors for a Lynden Board & Batten Job
Board and batten pricing depends on more than square footage. The factors below are the ones that actually move a bid up or down on a real Lynden home.
| Factor | Why it affects cost |
|---|---|
| Full board and batten vs. accent use | Covering an entire home costs more than using it as a gable or entry accent alongside lap siding |
| Tear-off vs. new construction | Removing and disposing of old siding, plus any sheathing repair, adds labor beyond a bare-wall install |
| Rainscreen / furring detail | Adding a drainage gap behind the panels is extra labor and material, and one we lean toward on this climate |
| Wall complexity | Corners, window and door count, and transitions to other siding profiles all add flashing and cutting time |
| Color and finish selection | Factory ColorPlus finishes vary by line; some premium colors carry a modest upcharge over standard options |
Why a Crew That Already Works Lynden Matters
Board and batten forgives fewer mistakes than lap siding in a climate this wet, because it concentrates seams and fasteners differently and depends more heavily on what's happening behind the panel than what's visible on the wall. A crew that installs it occasionally, in a drier region, doesn't build the same instinct for where wind-driven rain actually tests a vertical wall in Whatcom County. Working this area regularly means we've seen where these details fail when they're rushed, and we build every job assuming the same weather is coming back next winter, because it is.
If you're considering board and batten for a Lynden home, we're happy to walk the property, talk through where it makes sense as a full treatment versus an accent, and give you a straightforward, no-pressure estimate. There's a form below to get that conversation started.
