Lynden Siding Board & Batten in Custer: A Look That Has to Earn Its Keep
Board and batten shows up on a lot of wish lists in Custer right now — the clean vertical lines read as modern farmhouse on a new build and as a tasteful accent on an older ranch or Craftsman. It works on a gable end, a full elevation, or a mix with lap siding elsewhere on the house. But board and batten isn't just lap siding turned sideways. It's a different assembly, with more seams, more fasteners, and a different water path, and in a stretch of Whatcom County that sits close to salt water and gets driving rain for a good chunk of the year, those differences matter more than they would somewhere drier and calmer. This page is specifically about doing board and batten right for a Custer property, not a general primer on the style.
We work out of Lynden and cover Custer regularly as part of our normal service area, which means we've seen how this particular profile behaves on homes with this particular exposure — not in a lab, but on real roofs and walls a few miles from where we're based.
What Custer's Exposure Does to a Vertical Siding Profile
Custer sits close enough to the water that salt-bearing air reaches most properties in the area, not just the ones with a water view. Combine that with wind-pushed rain and a moss season that runs most of the year in shaded spots, and you get three separate stresses that a vertical board and batten wall has to handle differently than a horizontal lap wall does.
Salt Air and Exposed Fasteners
Board and batten uses more fasteners per square foot than lap siding, because the battens themselves are face-nailed or blind-nailed on top of the base panel joints. Every one of those fastener heads is a potential weak point if it's the wrong material or isn't seated and sealed correctly, and salt-laden air accelerates corrosion on hardware faster here than it would inland. Fastener spec isn't a cosmetic detail on this profile — it's one of the first things that shows wear if it's wrong.
Wind-Driven Rain Along Vertical Seams
Lap siding sheds water downward across overlapping horizontal courses. Board and batten instead relies on the batten covering a vertical seam between two flat panels, so the water management logic is different: the batten has to actually shed water off the joint rather than let it track behind. When rain comes in sideways off the wind, which it regularly does in this part of Whatcom County, a batten that's under-lapped, under-fastened, or caulked instead of properly detailed becomes the point where water gets behind the cladding.
A Long Moss Season on Shaded Elevations
Mild temperatures and steady moisture keep moss and mildew active across most of the calendar here, and board and batten's flat panel faces and shadow lines at each batten give organic growth more edges and texture to hold onto than a smooth lap profile does, especially on north-facing or tree-shaded walls. That's not a reason to avoid the look — it's a reason to get the drainage plane and panel spacing right the first time.
Why We Only Build Board & Batten in James Hardie Fiber Cement
Board and batten is available in vinyl, engineered wood, and fiber cement, and we've made a deliberate call to install it only in James Hardie fiber cement. That's a narrower stance than a lot of siding contractors take, and it's worth explaining rather than just stating.
- Vinyl board and batten panels are lightweight and budget-friendly, but they're a plastic extrusion that expands and contracts with temperature swings more than fiber cement does, and the batten lines are formed into the panel rather than built up as a separate, sealed assembly — which limits how well they actually direct water off a seam under sustained wind-driven rain.
- Engineered wood board and batten (like LP SmartSide) uses a treated wood-fiber core, and because this profile has more fastener penetrations than lap siding, there are simply more places where the factory coating has to stay intact for the life of the product. In a climate where wet weather is the default rather than the exception, that's a lot of ongoing exposure riding on a wood-based core.
- Traditional cedar board and batten is where the look originated, and it has real appeal, but it's organic, combustible, and needs a repaint or restain schedule kept up on a strict timeline. Moss finds a cedar surface especially easy to colonize in a climate that stays damp most of the year, which is exactly the failure mode board and batten is most exposed to here.
James Hardie fiber cement is inorganic — a cured blend of Portland cement, sand, and cellulose fiber — so it doesn't have a wood-based or petroleum-based core that swells, rots, or feeds insects. Its ColorPlus factory finish is baked on in multiple coats under controlled conditions before the boards leave the plant, which holds up differently against salt air and UV than a field-applied paint job on a batten profile with dozens of exposed edges.
What a Correct Board & Batten Installation Involves
Fiber cement's reputation rides on installation quality, and that's even more true on board and batten than on lap siding, simply because there are more seams and more fasteners doing the work of keeping water out.
| Installation Detail | Why It Matters on Board & Batten in Custer |
|---|---|
| Rain screen or drainage gap behind the panels | Gives any moisture that gets past a batten joint somewhere to drain and dry instead of sitting against the sheathing |
| Correct batten width, spacing, and fastener pattern | Keeps each seam properly covered and prevents the panel from working loose under wind load off the water |
| Fasteners rated for the coastal exposure, seated to manufacturer depth | Slows corrosion at the highest-fastener-density profile we install |
| Flashing at every horizontal butt joint and window/door head | Directs driving rain out and down instead of letting it track behind the panel run |
| Manufacturer clearance at grade, roofline, and deck ledger | Keeps splash-back and standing moisture off the bottom edge of the lowest course |
We send the same certified crew to every board and batten job rather than treating it as an interchangeable swap for whatever a crew is used to hanging. The material resists moisture and combustion on its own, but a rushed or generic install can still let water find its way behind it.
Design Choices That Actually Matter Here
Board and batten gives you real decisions to make beyond color, and a few of them affect long-term performance as much as looks:
- Reveal width — narrower battens and reveals read more traditional; wider spacing reads more modern farmhouse. Wider reveals also mean more exposed panel face per seam, which puts more emphasis on getting the drainage plane right behind it.
- Accent versus full elevation — a gable end, dormer, or single accent wall in board and batten paired with Hardie lap siding elsewhere is a common, cost-conscious approach that still gets the look without committing every wall to the higher fastener count of a full board and batten install.
- ColorPlus color selection — because the finish is factory-applied, the batten and base panel color match consistently across the whole run in a way that's harder to guarantee with field-painted trim.
Our Process for a Custer Board & Batten Project
We start with a walk-around that looks at each elevation separately rather than treating the house as one uniform surface — which walls take the brunt of the prevailing wind and rain, which stay shaded and damp longer after a storm, and what the existing sheathing looks like once we can get behind the old siding. That assessment shapes where we add extra flashing attention or adjust the drainage detailing, even within the same house. From there it's tear-off, a check of the sheathing and water-resistive barrier before anything new goes up, the board and batten install to spec, and a final walkthrough where we point out what we did and why, not just hand over a finished wall.
What Board & Batten Costs to Get Right
Board and batten in fiber cement generally costs more per square foot than lap siding in the same material, mostly because of the extra labor: individually fitting and fastening battens takes longer than running continuous lap courses.
| Factor | How It Affects the Price |
|---|---|
| Accent wall vs. full-house coverage | Smaller accent applications cost less in total but a similar or higher rate per square foot due to setup and trim work |
| Number of corners, dormers, and penetrations | Each one adds flashing and cut-and-fit labor specific to a vertical profile |
| Condition of existing sheathing once old siding comes off | Hidden rot or damage found mid-project is the most common source of change orders on any re-side |
| Maintenance over the life of the siding | Lower than wood-based board and batten since there's no repainting or recaulking schedule to keep up on a wood core |
We give a straight number after that initial walk-around rather than a rough phone estimate, because the corner count, penetration count, and sheathing condition genuinely change the labor on this profile more than they do on plain lap siding.
Keeping Board & Batten Looking Right Over Time
Fiber cement board and batten is low-maintenance compared to wood, but "low" isn't "none," especially with this climate's moss season working against shaded walls year-round.
- Rinse pollen, salt film, and general grime off the walls a couple of times a year with a garden hose and soft brush — skip the pressure washer, which can force water past joints it wasn't meant to handle.
- Walk the north-facing and tree-shaded elevations a couple of times during the wet season and look for early moss or mildew growth before it spreads.
- Check that gutters and downspouts are actually routing water away from the base of the walls, not dumping it against the lowest course.
- Look at caulking and sealant around windows, doors, and penetrations once a year, since these are the points most likely to need attention before the siding itself does.
- Note any battens that look loose or any hairline cracking after a hard freeze-thaw stretch and get them looked at rather than waiting for the next scheduled inspection.
Why a Local Crew — and a Free Estimate
A crew that already works Custer regularly knows which elevations in this specific area tend to take the worst of the wind and salt exposure, which lots stay shaded long enough to grow moss fast, and what the existing housing stock in this corner of Whatcom County tends to be sided with underneath. That's the kind of judgment that only comes from doing the work here repeatedly, not from a general siding background applied to an unfamiliar area.
