Board & Batten Siding Built for Kendall's Climate
Board and batten has a strong presence out in Kendall. The larger lots, the mix of farmhouse-style homes and newer custom builds, and the heavier tree cover away from downtown Lynden all suit the look — clean vertical lines that read as classic on an older property and modern on a new one. What doesn't get talked about enough is that board and batten is fundamentally a joint pattern before it's a style. Every seam where a batten covers the gap between two boards is a place water can try to work its way behind the siding, and out here that seam has to deal with salt-tinged marine air, wind-driven rain, and a moss season that can run most of the year on shaded, tree-lined walls.
This page covers what board and batten siding needs to do for a Kendall home specifically — the joint and drainage details that matter in this climate, what a correct installation actually involves, and why we build every one of these projects in James Hardie fiber cement rather than the other materials board and batten commonly gets installed in.

What Kendall's Weather Asks of a Vertical Siding Profile
Kendall sits further from the water than some of the other communities we work in, but the weather it sees is still shaped by the same Pacific systems that push moisture up the Nooksack valley, and the effect on a wall isn't much different. Add in the amount of tree cover on Kendall's larger, more rural lots, and you get a climate that's arguably harder on a vertical siding profile than a more open, in-town setting.
Salt Air and Driving Rain
Wind-driven rain doesn't fall straight down — it gets pushed sideways and up, which matters enormously on a vertical profile where every batten joint runs the full height of the wall. A joint that's fine in a light, straight-down rain can still take on water when wind pushes it up and under a batten edge. Salt-tinged marine air also accelerates corrosion on undersized or exposed fasteners over time, which is often where a failure starts years after installation, not on day one.
Shade, Tree Cover, and a Long Moss Season
Kendall's wooded lots and larger setbacks mean more walls sit in partial shade for much of the day, especially on north-facing elevations backed up against trees. That shade holds moisture against the siding surface far longer after a rain than an open, sun-exposed wall would, which is exactly the condition moss and algae need to take hold. A vertical batten profile with dozens of running seams gives that moisture more edges and joints to collect in than a flat lap profile does.
Why the Joint Pattern Is the Whole Story with Board & Batten
There are two common ways to build this look, and they perform differently. Knowing the difference matters before you compare bids.
| Style | How It's Built | Best Fit |
|---|---|---|
| Panel & Batten | Large vertical fiber cement panels installed first, with battens fastened over the panel seams | Larger wall sections, faster coverage, fewer total field joints to manage |
| True Board & Batten | Narrower individual vertical boards installed edge to edge, with battens covering every board-to-board joint | Traditional farmhouse look with a tighter, more textured board rhythm — common on Kendall's older-style homes |
Both styles are legitimate and both can perform well in this climate — but both depend entirely on what's happening behind the batten, not just how the front looks. That's where most of the real installation quality lives.
What a Correct Board & Batten Install Involves
A board and batten wall that's going to hold up in Kendall's conditions is built in layers, from the framing out. Skipping any one of these layers is usually invisible on installation day and shows up as a problem years later.
Drainage Plane and Rainscreen Gap
A weather-resistive barrier goes on the wall first, and on taller wall sections or heavily shaded elevations, a furring strip behind the siding creates a small air gap — a rainscreen — that lets any moisture that does get past the face of the siding drain and dry out instead of sitting against the sheathing. This detail matters more on a vertical profile than a horizontal one, since water tends to travel down the length of a batten joint rather than shedding off quickly.
Fastening and Reveal
Battens need to be fastened into framing or blocking with corrosion-resistant fasteners at the spacing the manufacturer specifies, not stretched further apart to save time. The reveal — the width of gap the batten covers — needs to stay consistent across the wall, both for the finished look and because an inconsistent reveal usually means inconsistent fastening underneath it.
Corners, Trim, and Transitions
Outside corners, window and door trim, and the transition where board and batten meets a different siding profile or material are where a lot of amateur installs fall apart first. Each of these needs proper flashing and sealant details behind the trim, not just a tight-looking caulk line on the surface that hides a gap underneath.
Horizontal Butt Joints
On taller walls, individual boards or panels eventually need a horizontal joint where one course ends and the next begins. These joints need to be flashed so water sheds over the top of the joint rather than running behind it — a detail that's easy to rush and hard to inspect once the wall is finished.
Why We Install This Only in James Hardie Fiber Cement
Board and batten shows up in vinyl, engineered wood, and traditional cedar as well as fiber cement, and each of those has real trade-offs worth understanding before you choose. Vinyl battens can warp and separate from the panel behind them with temperature swings. Engineered wood and cedar boards are more vulnerable at cut ends and exposed grain, which are unavoidable at every single batten joint on this profile — and that's precisely where Kendall's damp, shaded conditions do the most damage over time.
We install James Hardie fiber cement exclusively for board and batten because it's non-combustible, dimensionally stable across wet and dry cycles, and comes factory-finished with ColorPlus coating — including on the cut edges when properly sealed at installation — so the battens and boards aren't relying on a field-applied paint job to hold up at every joint. Hardie's HZ product lines are engineered for Pacific Northwest moisture exposure specifically, and the warranty is backed by a manufacturer with decades of performance data in exactly this climate, not a newer product still building its track record.
Cost Factors Worth Understanding
Board and batten bids for what looks like the same job can vary substantially, and the difference is almost always in scope, not markup.
| Factor | What It Affects |
|---|---|
| Panel & batten vs. true board & batten | Material quantity, labor time, and the finished texture of the wall |
| Rainscreen / furring strips | Long-term drainage performance on shaded or taller wall sections |
| Batten spacing and reveal width | Total board and fastener count, and the finished look |
| Trim and corner detailing | How thoroughly the highest-risk joints on the wall are protected |
| Existing siding removal and sheathing repair | Whether hidden moisture damage gets found and fixed before new siding goes on |
| Wall height and access | Staging, scaffolding, and labor time on taller or multi-story elevations |
An itemized written estimate that breaks out these components is worth far more than a single bottom-line number, and any contractor should be able to walk you through what's driving each part of the price.
How Our Process Works
- In-person walkthrough: We look at the actual walls, existing siding condition, and shade exposure in person, not from a photo.
- Written estimate: You get an itemized bid covering removal, sheathing repair if needed, rainscreen detail, board or panel selection, batten spacing, and trim — not a single vague number.
- Material selection: We help you choose between panel and batten or true board and batten, along with reveal width and ColorPlus finish, based on the style of the home.
- Removal and sheathing check: Old siding comes off and the sheathing underneath gets inspected and repaired before anything new goes on.
- Drainage plane, fastening, and trim installation: Every layer goes on to manufacturer specification, with extra attention at corners, horizontal joints, and window and door transitions.
- Final walkthrough: We review the finished wall with you and confirm everything before calling the job complete.
Why Hiring a Crew That Already Works in Kendall Matters
A crew that regularly installs siding out in Kendall already knows how much shade the tree-covered lots throw on north walls, how far wind-driven rain can push water up a vertical seam, and which elevations need a rainscreen gap versus which can get by without one. Board and batten in particular punishes generic installation habits, since every batten joint is a decision point, and a crew unfamiliar with this specific climate is more likely to treat all of them the same way instead of adjusting for shade, exposure, and wall height.
It also matters after the job is finished. A workmanship warranty only means something if the company behind it is still reachable in a few years, and a contractor with an ongoing, established presence in the area is the one you can actually call back.
A Practical Checklist Before You Choose a Board & Batten Contractor
- Do they specify panel & batten vs. true board & batten, and explain the difference?
- Is a rainscreen or furring detail included on shaded or taller wall sections?
- Does the estimate call out corner, trim, and horizontal joint flashing specifically?
- Do they install fiber cement, or a material more vulnerable at exposed batten edges?
- Do they carry current WA contractor licensing, liability insurance, and workers' compensation?
- Can they point to real, recent work in or near Kendall?
Signs Existing Board & Batten Siding Needs Attention
Board and batten siding tends to show problems at the joints long before the field of the boards looks bad, which is exactly why those joints deserve extra scrutiny during any inspection.
- Dark streaking or moss buildup concentrated along batten edges on shaded walls
- Soft spots or discoloration at the base of boards near grade
- Gaps opening up behind battens where fasteners have loosened or corroded
- Peeling or bubbling finish concentrated at cut ends and horizontal joints
- Staining on interior walls near window and door trim transitions
Catching these early is usually the difference between a targeted repair and a full re-side, so it's worth a look before the next stretch of wet weather rather than after.
