Blaine Siding Board & Batten Siding for Point Roberts Homes
Point Roberts occupies a strange spot on the map — a small American peninsula hanging off the bottom of the Tsawwassen peninsula in British Columbia, connected to the rest of Whatcom County only by water or by a drive that has to pass through Canada in both directions. That geography isn't just a curiosity for a homeowner here. It means every house on this point sits fully exposed to marine weather with almost no inland buffer, and it means the contractor working on that house needs to understand the logistics of this place, not just the carpentry.
Board and batten has become a popular choice on this stretch of coastline, and it's easy to see why — the vertical lines suit both the older cabin-style homes that make up a lot of the peninsula's housing stock and the newer builds going up along the water. What matters more than the look, though, is that board and batten is a joint-heavy profile. Every seam where a batten covers the gap between two boards is a potential path for water, and on a peninsula that catches wind and rain off two different bodies of water, those seams get tested more often than they would almost anywhere else in the county.
We install James Hardie fiber cement board and batten exclusively, and every fastening pattern, joint detail, and flashing line we build accounts for what this specific point of land does to a wall over time — not just what it looks like walking away from the job.
What Point Roberts' Exposure Does to a Board & Batten Wall
Weather From Two Directions
Most Whatcom County towns face weather from one general direction — off the bay, off the strait, whichever way the water sits. Point Roberts is a peninsula with water on multiple sides, Boundary Bay to the east and the Strait of Georgia to the west, which means a home here can take wind-driven rain from more than one exposure depending on the storm track. A board and batten wall built with only one prevailing wind direction in mind is the kind of assumption that doesn't hold up on this point.
Wind-Driven Rain Against Vertical Seams
Board and batten's vertical joints give wind-driven rain a straight run of seam to work against, from the top of the wall to the bottom. When that rain is coming in sideways off open water rather than falling straight down, a batten that's caulked tight instead of properly lapped with clearance becomes a place for moisture to collect against the fastener line instead of shedding off the wall.
Salt Air and Fastener Corrosion
Being surrounded by saltwater rather than sitting near one edge of it means a steadier, more constant salt exposure than most inland or even single-shoreline properties in the county see. Board and batten uses more fasteners per square foot than standard lap siding because both the boards and the battens need to be pinned down, so getting fastener corrosion resistance right carries more weight here than on almost any other siding profile in almost any other part of Whatcom County.
A Long Moss Season on Shaded Walls
Mild temperatures and near-constant marine moisture give moss and mildew a growing season that runs most of the year on north-facing and tree-shaded walls. Point Roberts has plenty of both — wooded lots and homes tucked under tree cover away from the waterfront — and a batten seam that traps moisture against the substrate instead of letting it dry is exactly the kind of spot moss and softening substrate take hold first.
Why Product Choice Matters More on This Profile
A joint-heavy profile amplifies whatever weaknesses a siding material already has, because more of the material's edge is exposed to weather and there are more places for water to test the installation. 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. On a peninsula this exposed, with this many seams per wall, we made a professional decision to stand behind one system rather than offer something that shifts long-term maintenance risk onto the homeowner.
| Material | Behavior at Batten Seams | Maintenance in This Exposure | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss, salt, and fading | 30+ years with proper install |
| LP SmartSide (engineered wood) | Moisture-sensitive at cut edges and fastener holes | Moderate to high; edge sealing needs regular upkeep | 15-25 years, exposure-dependent |
| Vinyl | Can warp, gap, or rattle at battens under sustained wind | Low, but hides moisture problems until they're advanced | 20-30 years, variable in high-wind exposure |
| Cedar | Absorbs moisture at every seam without regular sealing | High; refinishing on a recurring cycle in salt air | 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 that's built entirely out of vertical seams. The factory-applied ColorPlus finish also means the cut edges we prime on site are the exception rather than the rule, unlike a field-painted material where the whole wall's finish depends on paint holding up against salt air year after year.
What a Correct Board & Batten Install Actually Involves
The finished look is simple — boards up, battens over the seams — but there's more happening behind that surface than most siding profiles require, and skipping any of it tends to show up as a problem two or three wet seasons later rather than on install day:
- Weather-resistive barrier installed and correctly lapped before any siding goes up, sized for a wall that may take rain from more than one direction
- A drainage gap or rainscreen behind the siding so moisture that gets past the surface can dry out rather than sit against the sheathing
- Corrosion-resistant fasteners at the manufacturer's specified spacing, sized and rated for sustained marine salt exposure
- Battens set with proper clearance rather than caulked flush, so the wall can shed water instead of trapping it at the seam
- Flashing and lapping detailed correctly at windows, doors, corners, and the base of the wall — the points where a vertical profile meets a horizontal transition
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before they go up
The Logistics Most Contractors Never Plan For
Point Roberts is part of Whatcom County, but it isn't connected to the rest of it by road. Getting a crew, tools, and siding materials onto the peninsula means crossing the Canada-US border, and getting a dumpster of tear-off debris back off it means crossing again. That's routine for a crew that works this area regularly and a genuine headache for one that doesn't — material deliveries have to be scheduled around border wait times, crews need to carry the right documentation for hauling tools and equipment across, and a job that runs into an unexpected material shortage can lose a lot more time here than it would on a job a few miles inland where a supply house is a short drive away.
None of that shows up in a siding spec sheet, but it shows up in how smoothly a project actually runs. A crew that's already built this logistics planning into how they schedule and stage a Point Roberts job avoids the delays that catch contractors off guard the first time they try to work out here.
Our Process for a Point Roberts Board & Batten Project
Walkthrough and Assessment
We start by looking at which walls face which body of water, how much tree cover keeps certain sides of the house shaded and slow to dry, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes on. Board and batten over a wall with hidden rot just buries the same problem under new material.
Planning Materials and Logistics Before Install Day
Because everything — crew, tools, siding, trim, disposal — has to cross the border to get to or from this job site, we plan material orders and delivery timing with that in mind well before the first board goes up. Working out batten spacing, corner details, and window and trim transitions on paper first also means less field improvisation once crews are on-site, which matters more here since a forgotten detail can't be solved with a quick run to the nearest supply house.
Installation to Manufacturer Spec
Every fastener, gap, and flashing lap follows James Hardie's published installation requirements for this climate zone. That's what keeps the manufacturer's warranty intact, and it's what determines whether the wall performs the way it's supposed to for decades rather than years on a peninsula that doesn't give a wall many places to hide from the weather.
Final Walkthrough
We walk the finished job with you, cover what the minimal maintenance board and batten actually needs looks like, and make sure you know what a healthy seam and a problem seam look like if you ever want to check the wall yourself.
Why Hire a Crew That Already Works Point Roberts
A siding job on this peninsula is a different undertaking than the same job a few miles away on the mainland part of the county, and not just because of the weather. A crew that already has the border logistics figured out, that already knows which walls on this point take the worst of the wind and which stay shaded and damp longest, and that's installed board and batten through multiple wet seasons out here has already made the mistakes that cost other contractors time and money on their first Point Roberts job. That experience is the difference between a project that runs on schedule and one that stalls out waiting on a material order that didn't account for the drive.
Cost Factors for Board & Batten in Point Roberts
Board and batten generally costs more per square foot than standard lap siding, mainly from the added material — battens on top of boards — and the extra labor of fastening and detailing two layers instead of one. On this peninsula specifically, a few additional factors move the number:
| Factor | Why It Matters |
|---|---|
| Wall exposure and orientation | Walls facing open water need more attention to fastening and flashing than sheltered, wooded sides |
| Existing wall condition | Salt-air corrosion or trapped moisture found during tear-off needs repair before new siding goes up |
| Material and crew logistics | Deliveries and disposal both cross the border, which factors into scheduling and staging |
| 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 |
We'll walk your specific property and give you real numbers rather than a rough estimate off square footage — two homes on this peninsula with similar footprints can have very different scopes depending on exposure, existing wall condition, and access.
Getting It Right the First Time
Because the battens cover the seams between boards, correcting a bad board and batten install usually means pulling battens, boards, or both, rather than a simple patch. On a peninsula where every material order and every load of debris has to cross a border, a redo costs more in time than it would almost anywhere else in the county. That's exactly why we treat the planning phase of a Point Roberts project as carefully as the install itself.
