Lynden Siding Board & Batten Siding for Blaine Homes
Board and batten keeps showing up on request lists for Blaine homes, and it's easy to see why — the vertical lines suit both the older cottages scattered near the harbor and the newer builds going up further from the water, giving a home a clean, tailored look that lap siding doesn't quite match. What often gets glossed over in the excitement of picking a profile is that board and batten is fundamentally a seam pattern. Every vertical joint where a batten covers the gap between two boards is a place water can try to work its way behind the wall. In a town sitting right on Drayton Harbor and Semiahmoo Bay, with salt-laden marine air rolling in off the water, driving rain most of the fall and winter, and a moss season that runs long on shaded northern walls, how those seams are built matters as much as which siding brand ends up on the invoice.
Lynden Siding Company is based inland, in the Nooksack Valley farm country around Lynden, but a good share of our board and batten work happens out toward the coast in Blaine and the surrounding shoreline communities. We install James Hardie fiber cement exclusively, and every fastening pattern, batten gap, and flashing detail on a Blaine job gets built around what this specific stretch of Whatcom County coastline does to a wall over ten, twenty, and thirty years — not around what looks acceptable on the day the crew packs up.
What Blaine's Coastal Exposure Asks of a Board & Batten Wall
Wind-Driven Rain Off the Water
Blaine sits close enough to open water that rain rarely just falls straight down — wind off Semiahmoo Bay and the Strait of Georgia pushes it sideways into walls, and a vertical siding profile with battens running the full height of the wall gives that wind-driven rain a lot of joint length to test. A batten fastened tight with no room to shed water, or sealed with caulk instead of properly lapped and back-primed, turns into a wick that draws moisture toward the fastener line instead of directing it away from the wall.
Salt Air and Fastener Corrosion
The steady salt exposure this close to the water is hard on any exposed metal, and board and batten uses more fasteners per square foot than standard lap siding because both the boards and the battens need to be secured independently. That makes fastener spec — corrosion resistance, correct length, correct spacing — carry more weight on a Blaine job than it would on a similar house set back from the coast.
A Long Moss Season on Shaded Walls
North-facing and tree-shaded walls anywhere in Whatcom County hold moisture longer than sun-exposed ones, and Blaine's marine layer stretches that damp window even further than it runs a few miles inland in Lynden. That extended dampness is exactly what moss and mildew need to take hold, and a batten set tight against a board with no room to breathe traps that moisture right where it can't dry — a slow path toward seam staining, softened substrate, and paint failure that shows up years after the crew that installed it is long gone.
Why Material Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, because it carries more seams and more exposed edge per square foot than almost any other profile. That's a big part of why we don't offer LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. Those are legitimate products, and plenty of contractors install them well — but on a profile this seam-heavy, in a location this consistently wet and salt-exposed, we standardized on one system we're willing to stand behind completely.
| Material | Behavior at Batten Seams | Maintenance on the Coast | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; won't swell or cup at the joint | Low; factory finish resists salt staining and moss | 30+ years installed to spec |
| LP SmartSide (engineered wood) | More sensitive to moisture at cut edges and fastener holes | Moderate; edge sealing needs regular upkeep | 15-25 years, worse near salt air |
| Vinyl | Can warp or gap at battens under sun and cold cycling | Low visible upkeep, but trapped moisture is hard to spot | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High; recurring painting or resealing needed | 15-25 years with consistent upkeep |
Fiber cement's core doesn't expand and contract with moisture the way wood-based products do, which matters most on a profile built entirely from vertical seams. Hardie's factory-applied ColorPlus finish also means the cut edges we prime in the field are the exception rather than the rule — unlike a field-painted material, where the whole wall's protection depends on how well that paint holds up against salt air year after year.
What a Correct Board & Batten Install Actually Involves
The finished look of board and batten is simple — vertical boards, battens covering the seams — but a correct install has more happening behind that surface than most other siding profiles, especially this close to the water:
- House wrap or weather-resistive barrier installed and properly lapped 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 sheathing
- Corrosion-resistant fasteners set at the manufacturer's specified spacing, not just enough to hold the board in place
- Battens set with the clearance Hardie's installation instructions call 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 they go up
Skip any one of these steps and the wall can still look right for a season or two. The problems that follow — staining at the seams, soft spots near the base, paint failure along the battens — take a few wet winters to surface, which is exactly why a corner-cutting install can get away with it right up until the homeowner is the one dealing with the repair bill.
Our Process for a Blaine Board & Batten Project
Walkthrough and Assessment
We start by looking at the walls actually involved — which ones take the weather head-on off the water, which are shaded and slow to dry, and whether the existing wall assembly already has moisture trapped behind it. Putting new board and batten over a wall with hidden rot or inadequate drainage just buries the same problem under new material and a fresh coat of paint.
Planning the Details Before Install Day
We work out batten spacing, corner details, and how the siding will meet windows, trim, and rooflines before any crew starts cutting material. On a profile with this many seams, settling the details on paper first keeps the crew from improvising in the field, which is usually where corners end up getting 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 what keeps the manufacturer's warranty intact, and it's why the wall performs the way it's supposed to for decades rather than years.
Final Walkthrough
We walk the finished job with you, cover what little maintenance board and batten actually needs in this climate, and make sure you know what a healthy seam looks like if you ever want to check the wall yourself down the road.
Why Hire a Crew Based in Lynden That Already Works Blaine
Lynden sits inland, and the climate there — while still plenty wet by most standards — doesn't carry the same direct salt exposure as a shoreline town like Blaine. A crew that only ever installs siding a few miles from the Nooksack Valley and treats a Blaine job the same way is missing something. We've installed board and batten on enough homes along this stretch of the Whatcom County coast to know which orientations need extra attention because of direct water exposure, how much batten clearance actually holds up against Blaine's marine air versus what a generic install guide assumes, and where a rainscreen gap earns its keep versus where it's a nice-to-have. That judgment doesn't show up on a spec sheet or a brochure — it's the difference between a 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 the Blaine Area
Board and batten typically runs more per square foot than standard lap siding, mostly because of the added material — battens on top of 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 Blaine home:
| Factor | Why It Matters |
|---|---|
| Distance and direct exposure to the water | Homes closer to the harbor or bay may need tighter fastener spacing and more careful flashing |
| 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 |
| Access and site conditions | Narrow lots or limited equipment access can add labor time |
We'll walk your specific home and give you real numbers rather than a rough estimate based on square footage alone — two houses of the same size can land at very different board and batten costs depending on how many of these factors are actually in play.
Getting It Right the First Time
Board and batten isn't 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 why we treat the planning and detailing phase of a Blaine 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 put up wrong.
