Board & Batten Siding in Kendall: A Style That Has to Earn Its Keep
Board and batten has become one of the most requested looks for homes around Kendall, and it's easy to see why. The vertical lines read as clean and modern on newer builds, and they suit the barn-and-farmhouse character that shows up on a lot of Whatcom County properties too. But board and batten is not just a look you can bolt onto any wall and expect it to hold up. It's a system — a base panel, a set of battens, a fastening pattern, and a set of gaps and flashings that all have to work together. Get that system right and it will look sharp and shed water for decades. Get it wrong, and the same vertical joints that make the style attractive become the exact places water finds its way in.
That distinction matters more in Kendall than it does in a lot of places, because the climate here doesn't give sloppy siding work much room for error.

What Kendall's Climate Actually Does to Vertical Siding
Kendall sits inland from the coast but still gets a steady dose of salt-laden air moving in off the Strait of Georgia and Bellingham Bay, especially on windier days. That salt air accelerates corrosion on any exposed metal fastener or flashing that isn't rated for it, and it slowly breaks down finishes that weren't built to handle it. Combine that with the driving rain that comes through Whatcom County for a good chunk of the year — often pushed sideways by wind rather than falling straight down — and you get moisture pressure hitting wall assemblies from angles that a lot of siding details were never designed for.
Then there's moss season, which around here isn't really a season so much as most of the year. Anywhere shade, moisture, and still air combine — north-facing walls, areas under eaves, spots behind landscaping — organic growth wants to take hold. On a board and batten wall, the batten strips create dozens of narrow ledges and vertical channels where moisture can sit longer than it should. If the material underneath can't tolerate that sustained dampness, or if the installation didn't leave any way for that moisture to drain and dry out, you end up with soft spots, staining, and eventually rot behind the battens — usually discovered only once it's already spread.
None of this means board and batten is a bad choice for Kendall. It means the material and the installation both have to be matched to what this climate actually does to a wall, year after year.
What a Correct Board & Batten Installation Involves
Board and batten siding lives or dies on details most homeowners never see once the wall is closed up. A correct installation includes:
- Proper weather-resistive barrier and rainscreen gap — the underlying house wrap has to be installed shingle-style so water sheds down and out, and a drainage gap behind the siding lets any moisture that does get in dry out instead of sitting against the sheathing.
- Correct panel and batten fastening — base panels and battens need to be fastened into framing at the intervals and offsets the manufacturer specifies, not just wherever is convenient, and battens should not be over-driven or nailed through both layers in a way that traps water.
- Flashing at every horizontal transition — window heads, door heads, roof-to-wall intersections, and any horizontal trim need step or Z-flashing that directs water out and away, not into the wall cavity.
- Gaps sized for the region — vertical and horizontal joints need expansion clearance and sealed or capped terminations appropriate for a climate with real seasonal moisture swings, not the tighter tolerances that work in drier regions.
- Corrosion-resistant fasteners — given the salt air that reaches Kendall, fastener and flashing metal needs to be rated for a coastal-influenced environment, not standard interior-grade hardware.
Skip any one of these and the wall might look fine for a year or two. The problems that show up from a shortcut installation tend to surface three, five, or ten years in — right about the time they're expensive to fix.
Why the Batten Layout Isn't Just Cosmetic
Batten spacing gets treated as a design decision — wider or narrower for a particular look — but spacing also affects how the wall handles water and wind load. Battens spaced and fastened to manufacturer spec help the whole assembly move together during temperature swings and wind events instead of individual boards working loose. On a site with regular driving rain, that consistency is part of what keeps water managed at the surface instead of finding a gap to exploit.
Why We Install Board & Batten Only in James Hardie Fiber Cement
We install James Hardie exclusively, and board and batten is one of the clearest examples of why that standard matters. Board and batten is traditionally done in solid wood or engineered wood panels, both of which look great on day one. The problem is what happens at year five or ten in a climate like Kendall's: wood-based battens sitting in a damp, shaded microclimate are exactly the conditions that invite swelling, splitting, and rot, and once moisture gets behind a batten it's hard to catch early because the damage is hidden.
James Hardie's fiber cement board and batten system — factory-primed panels and battens, or the ColorPlus prefinished option — is built from cement, sand, and cellulose fibers. It doesn't absorb water the way wood does, it won't support rot, and it's non-combustible, which matters given Whatcom County's dry-season wildfire smoke and occasional red flag conditions. The ColorPlus finish is baked on at the factory under conditions a job-site paint crew can't replicate, and it carries a finish warranty separate from the substrate warranty — so the color holds up to UV and salt air exposure without homeowners needing to repaint every few years.
That's the whole reason we don't offer LP SmartSide, vinyl, Cemplank, Allura, or raw cedar and spruce as board and batten options. Each of those has a place in the market and each has real strengths. But for a wall system that has to stand up to Kendall's specific combination of salt air, sideways rain, and near-constant moss pressure, fiber cement from James Hardie is the product we're willing to put our name behind.
Comparing Board & Batten Material Options
| Material | Moisture Tolerance in Wet, Shaded Areas | Finish Longevity | Maintenance Burden |
|---|---|---|---|
| James Hardie Fiber Cement | Does not swell or rot; engineered for wet climates | ColorPlus factory finish, separately warrantied | Occasional wash; no repainting cycle with ColorPlus |
| Solid Wood / Cedar | Prone to splitting, swelling, and rot in persistent shade/moisture | Site-applied finish weathers faster | Regular refinishing and moisture monitoring |
| Engineered Wood (LP-style) | Better than raw wood but still wood-based; edge and moisture sensitivity remain | Factory finish varies by product | Moderate; watch for edge swelling |
| Vinyl-Style Panels | Doesn't rot, but can warp or crack in temperature swings; not typically installed with true battens | Color can fade with sustained UV/salt exposure | Low, but limited repair options if damaged |
Our Process for a Kendall Board & Batten Project
Every board and batten job we do in Kendall starts with an on-site look at the specific wall exposures — which sides face prevailing wind and rain, where shade and moisture linger longest, and what's currently happening at window and roof transitions. From there:
- We assess the existing wall assembly and address any moisture or rot issues before new siding goes on — covering over a problem is not an option.
- We install or verify a properly lapped weather-resistive barrier and rainscreen gap.
- We install James Hardie base panels and battens to manufacturer spec, with fastening and spacing set for this climate.
- We flash every window, door, and horizontal transition individually rather than relying on caulk as a substitute for flashing.
- We walk the finished job with the homeowner and point out how the system is designed to shed water, so there are no surprises later.
What to Expect Over the Life of the Siding
A correctly installed James Hardie board and batten wall in Kendall should need very little from a homeowner: an occasional rinse to keep pollen, dust, and moss spores from building up, and a visual check after major storms to confirm flashing and caulking at penetrations are intact. There's no repainting cycle to plan for with ColorPlus finishes, which is a meaningful difference from wood-based board and batten over a 15-to-20-year ownership window.
A Practical Checklist Before You Commit
- Ask what weather-resistive barrier and rainscreen approach will be used behind the siding.
- Confirm the fastener and flashing metal is rated for a salt-air environment.
- Ask how window heads, door heads, and roof-to-wall transitions will be flashed — get specifics, not "we'll seal it up."
- Confirm batten spacing and fastening will follow manufacturer installation instructions, not just an eyeballed layout.
- Ask whether the crew has installed board and batten specifically in this area before, not just siding in general.
- Get the warranty terms in writing — both the product warranty and, for James Hardie ColorPlus, the separate finish warranty.
Why Local Experience in Kendall Matters
Siding crews that haven't worked this specific area can miss things that aren't obvious from a spec sheet — which walls in Kendall tend to hold shade and moss longest, how far wind-driven rain actually reaches under an eave here versus a drier inland town, or which flashing details have proven themselves over multiple wet seasons in this part of Whatcom County. A crew that already works Kendall has seen how board and batten holds up here specifically, not just how it's supposed to perform on paper. That's the difference between a wall that looks good in photos and one that's still performing exactly as it should ten winters from now.
