Blaine Siding Board & Batten Siding for Custer Homes
Custer sits in the open agricultural flatland north of Ferndale, close enough to Blaine and the Canadian border that marine air off the Salish Sea and Semiahmoo Bay reaches it on most storms, even though the town itself is set back from the shoreline. It's also a place where board and batten has always made visual sense — the vertical profile echoes the barns, outbuildings, and farmhouses that define a lot of the area, in a way that a lap-sided ranch house doesn't quite match. That's part of why we get more board and batten requests out of Custer than from some of the more built-up parts of Whatcom County.
The look is only half the story, though. Board and batten is a joint-heavy profile — every seam between a board and the strip covering it is a place water can try to work its way behind the siding — and Custer's flat, open exposure gives wind-driven rain a clean run at those seams that a more sheltered, tree-lined lot wouldn't. We install James Hardie fiber cement board and batten exclusively, and every fastening pattern, clearance, and flashing detail on a Custer job is built around what this specific stretch of the county does to a wall over ten, twenty, and thirty years.
What Custer's Open Exposure Asks of a Board & Batten Wall
Wind-Driven Rain With Nothing to Break It
A lot of Custer properties sit on larger lots with open sightlines across fields, and that openness cuts both ways. It's part of the appeal of living out here, but it also means storms coming off the water don't lose much force before they hit a wall. Rain arrives sideways more often than straight down, and a vertical siding profile with battens running the full height of the wall gives that wind-driven rain a lot of joint to test. A batten installed without proper clearance, or sealed with caulk instead of built to shed water on its own, is exactly the kind of detail that fails first in this kind of exposure.
Salt Air Carried Inland
Custer isn't waterfront, but it's close enough to Semiahmoo Bay and the broader Salish Sea that salt-laden air rides inland on winter storms regularly. Board and batten uses more fasteners per square foot than standard lap siding, since both the boards and the battens have to be secured, so getting fastener spec right — corrosion-resistant, correctly sized, correctly spaced — matters more on this profile than on most others, especially in air that's carrying salt even a few miles from the coastline.
A Long Moss and Mildew Season
Mild temperatures and steady moisture add up to a moss and mildew season that runs most of the year on shaded and north-facing walls throughout Whatcom County, and Custer's mix of open farmland and tree-lined lots means some walls dry out fast in the wind while others stay damp far longer. A batten set tight against a board with no room for airflow behind it traps that dampness right where it can't dry, which is a slow path toward staining, softened substrate, and paint failure right at the seam.
Why the Farmhouse Look Doesn't Excuse a Weak Wall
Board and batten's popularity in and around Custer often comes from wanting that classic farmhouse or rural exterior — clean vertical lines, a look that fits a property with some acreage or an agricultural history. That's a completely reasonable reason to choose the profile. But the aesthetic doesn't change what the wall has to survive. A board and batten wall on a five-acre Custer lot faces the same wind-driven rain and salt-tinged air as one on a smaller in-town parcel, often with less windbreak from neighboring structures or mature trees. Choosing the look is the easy part; building it to actually hold up in this exposure is where the real work is.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, because the joint count is higher and more material edge is exposed to weather. That's part of why we don't offer LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. Those are legitimate products, and other contractors install them competently — but on a profile with this many seams, in an exposure this consistently wet and wind-driven, we standardized on one system we trust completely.
| Material | Behavior at Batten Seams | Maintenance in Custer's Exposure | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss and fading | 30+ years with proper install |
| LP SmartSide (engineered wood) | More sensitive to moisture at cut edges and fastener holes | Moderate; edge sealing needs upkeep | 15-25 years, climate-dependent |
| Vinyl | Can warp or gap at battens with wind and temperature swings | Low, but hidden moisture issues are hard to catch | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High; repainting or resealing on a recurring cycle | 15-25 years with consistent upkeep |
James Hardie's fiber cement core doesn't expand and contract with moisture the way wood-based products do, which is exactly the property that matters most on a profile built entirely out of vertical seams. The factory-applied ColorPlus finish, engineered for this climate zone, also means the cut edges we prime on site are the exception rather than the rule — unlike field-painted materials, where the whole wall's protection depends on paint quality holding up outdoors, year after year, on an exposed lot with no windbreak.
What a Correct Board & Batten Install Actually Involves
The finished look of board and batten is simple — vertical boards, battens over the seams — but a correct install has considerably more happening behind that surface:
- House wrap or weather-resistive barrier installed and lapped correctly before any siding goes up
- A drainage gap or rainscreen behind the siding so moisture that gets past the surface can dry out instead of sitting against the wall
- Boards fastened with corrosion-resistant fasteners at the manufacturer's specified spacing, not just enough to hold the material up
- Battens set with the clearance Hardie's install spec calls for, not caulked tight, so the wall can shed water instead of trapping it
- Properly flashed and lapped transitions at windows, doors, corners, and the base of the wall, where the vertical run meets a horizontal surface
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before installation
Skip any one of these and the wall can still look right for a season or two. The problems that show up when they're skipped — staining at seams, soft spots near the base, paint failure along battens — take a few wet winters to surface, which is exactly why they're easy for a rushed install to get away with until the homeowner is the one dealing with it.
Our Process for a Custer Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved — which face the open exposure directly, which sit in the lee of a tree line or outbuilding, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes up. Board and batten over a wall with hidden rot or inadequate drainage just buries the same problem under new material.
Detailing the Plan Before Install Day
We work out batten spacing, corner details, and how the siding will meet windows, trim, and rooflines before crews start cutting material. On a profile with this many seams, settling the details on paper first avoids the kind of field improvisation that's where corners tend to get cut.
Installation to Manufacturer Spec
Every fastener, gap, and flashing lap follows James Hardie's published installation requirements for this climate zone, not a generic national standard. That's part of what keeps the manufacturer's warranty intact, and part of why the wall performs the way it's supposed to for decades, not just for the first few dry summers.
Final Walkthrough
We walk the finished job with you, cover what maintenance actually looks like for board and batten — there's very little with this material, but it's worth knowing what to watch for — and make sure you know what a healthy wall looks like if you ever want to check it yourself.
Why Hire a Crew That Already Works Custer
Board and batten rewards experience with this specific exposure in a way a lot of siding profiles don't, because the failure points are subtle and slow to appear. A crew that's installed this profile on open, wind-exposed Custer lots through multiple wet seasons has already seen which orientations need extra fastener attention because there's no windbreak, how much batten clearance actually holds up in this level of exposure versus what a generic install guide assumes, and where a rainscreen gap earns its keep on a shaded wall versus an open one. That judgment doesn't show up on a spec sheet, and it's the difference between a board and batten wall that still looks and performs the same in fifteen years and one that's showing seam staining by year five.
Cost Factors for Board & Batten in Custer
Board and batten typically costs more per square foot than standard lap siding, mainly because of the added material (battens over boards) and the extra labor of fastening and detailing two layers instead of one. Beyond the base material, a few things move the price on a given Custer property:
| Factor | Why It Matters |
|---|---|
| Wall height and complexity | More corners, dormers, and transitions mean more cuts and flashing details |
| Existing wall condition | Rot or moisture damage found during tear-off needs repair before new siding goes up |
| Batten spacing and reveal | Tighter spacing uses more material and more fastening labor |
| Trim and window detailing | More openings mean more flashing and finish work around each one |
| Lot exposure and access | Open, wind-exposed sites and larger rural lots can affect staging and labor time |
We'll walk your specific property and give you real numbers rather than a rough estimate off square footage alone — two homes with similar square footage can land very differently on cost depending on how many of these factors come into play, and how exposed the lot actually is.
Getting It Right the First Time
Board and batten is not a forgiving profile to redo. Because the battens cover the seams between boards, correcting a bad install usually means pulling battens, boards, or both, rather than a simple patch job. That's part of why we treat the planning and detailing phase of a Custer project as seriously as the install itself — the cost of getting it right the first time is a lot lower than the cost of tearing out a wall that was installed wrong for an exposure this demanding.
