Blaine Board & Batten Siding for a Peninsula Community
Point Roberts sits on its own patch of ground — a small U.S. community attached to the mainland only through Canada, surrounded on three sides by the Strait of Georgia. That geography gives homes here a look that suits board and batten well: clean vertical lines, a farmhouse or modern-coastal feel, and a profile that reads well against open water and evergreen backdrops. It also means the homes take weather most inland Whatcom County houses never see in the same combination.
This page is about one product applied in one place: board and batten siding, installed correctly, on homes in and around Point Roberts. We're not going to give you a generic rundown of a popular siding style. We're going to walk through what the local climate actually does to vertical siding over time, what a correct installation has to account for, and why the crew you hire for this particular job matters more here than in a lot of other places.
What the Point Roberts Climate Does to Siding
Three things define exterior conditions on this peninsula, and all three show up in siding failures we see on older homes.
Salt Air
Being surrounded by saltwater means airborne salt is a constant, low-grade presence on every exterior surface — fasteners, trim, caulk joints, and the siding face itself. Salt accelerates corrosion in anything metal and speeds up the breakdown of coatings that aren't formulated to resist it. Over years, that shows up as rusting fastener heads bleeding through paint, degraded caulk at joints, and faded or chalking finishes on lower-grade materials.
Driving Rain
Storms off the strait don't just fall straight down — wind-driven rain hits the sides of a house directly, and vertical board and batten has more seams (the batten strips themselves) than a lot of other siding profiles. Every one of those seams is a place water can find a way behind the siding if it isn't detailed correctly.
A Long Moss Season
Cool, damp, and shaded conditions for much of the year mean moss and algae get a long runway to establish themselves, especially on north-facing walls, under eaves, and anywhere airflow is restricted. Moss holds moisture against the siding surface far longer than open air would, which is bad news for any material that isn't dimensionally stable when wet.
None of this is unique to Point Roberts in isolation — plenty of Pacific Northwest coastal towns deal with salt, rain, and moss. What's unique is having all three at once, on a peninsula with essentially no buffer from open water.
Why Board & Batten Fits This Environment — When It's Built Right
The vertical board and batten profile has a real functional advantage in wet climates: the battens cover the seams between panels, and water tends to run down the face of the boards rather than pooling in horizontal laps. That's part of why the style has deep roots in wet-climate agricultural buildings — it wasn't chosen just for looks.
But that advantage only holds if the assembly behind the boards is done correctly. Board and batten siding that's face-nailed directly to sheathing with no drainage plane, or that uses a batten material that swells and shrinks with moisture, can trap water behind it — which is worse than a siding style with fewer seams but proper drainage. The style isn't a shortcut around good building science. It still needs one.
What Correct Board & Batten Installation Involves
A board and batten job that will actually hold up on the Point Roberts side of Whatcom County needs to get several things right, in this order:
- A drainage plane behind the siding. A weather-resistive barrier and, ideally, a rainscreen gap that lets any moisture that does get behind the siding drain and dry out instead of sitting against the sheathing.
- Correct fastening. Battens and base boards fastened with corrosion-resistant fasteners rated for the material and driven into framing, not just sheathing — loose fastening is one of the most common causes of early failure in vertical siding near saltwater.
- Sealed, flashed penetrations. Every window, door, hose bib, and light fixture penetration needs to be flashed and sealed before the siding goes on, not caulked afterward as an afterthought.
- Dimensionally stable material. Boards and battens that won't cup, swell, or split as they cycle through Point Roberts' wet winters and drier summers.
- Factory-applied finish. A finish baked on in a controlled environment holds color and resists moisture intrusion far better than field-applied paint, especially in a salt-air environment that's hard on coatings.
Skip any one of these and you don't get a slightly worse siding job — you get a job that looks fine for a couple of years and then starts failing from the inside out, which is the expensive kind of problem because it isn't visible until it's advanced.
Why We Install James Hardie Board & Batten — and Not the Alternatives
We only install James Hardie fiber cement siding. For board and batten specifically, that means James Hardie's vertical panel systems paired with HardieTrim battens, finished in a factory-applied ColorPlus finish. We don't install vinyl board and batten, engineered wood (LP SmartSide) board and batten, or primed wood boards and battens — and on a peninsula dealing with salt air, driving rain, and a long moss season, the reasons matter more than they would somewhere drier and more sheltered.
| Material | How it handles this climate | Long-term trade-off |
|---|---|---|
| Vinyl board & batten | Won't rot, but expands and contracts significantly with temperature swings, which stresses seams and fasteners over time | Can warp or crack in impact; color is molded-in and fades over years of UV and salt exposure with no way to refinish |
| Engineered wood (LP SmartSide) | Wood-based core is vulnerable if moisture gets behind it or sits at cut edges and seams | Requires diligent caulk maintenance at every joint to keep water out — a real burden with this many battens |
| Primed wood boards | Traditional look, but wood moves with moisture and needs a maintained paint film to stay protected | Highest ongoing maintenance — repainting cycles are more frequent in a salt-air, high-moisture environment |
| James Hardie fiber cement | Non-combustible, dimensionally stable, engineered to resist moisture-related damage | Requires professional installation to the manufacturer's spec to get full performance and warranty coverage |
We're not going to tell you the other options are junk — vinyl and engineered wood siding both have a place, and plenty of homes wear them fine in milder conditions. What we won't do is put a maintenance-hungry or moisture-sensitive product on a home that's already dealing with salt air, wind-driven rain, and a moss season that runs half the year. James Hardie's fiber cement composition doesn't absorb water the way wood-based products can, doesn't expand and contract the way vinyl does, and holds its ColorPlus finish through UV and salt exposure that fades painted or molded-in color faster. That's the whole reason we standardized on it.
Working in Point Roberts: Why Local Experience Actually Matters Here
Point Roberts is geographically separate from the rest of Whatcom County — the only land route in and out crosses an international border. That's not a small detail for a construction project. Material deliveries, crew scheduling, and even simple things like running back for a forgotten part all take longer and require more planning than they would on a job ten minutes down the road on the mainland side of the county.
A contractor who doesn't regularly work in Point Roberts will often quote it like any other job, then run into the border-crossing logistics mid-project — which turns into delays, rescheduled crew days, and a project that drags. A crew that already works this area builds the border crossing, ferry-adjacent scheduling quirks, and material staging into the plan from day one, so your project timeline reflects reality instead of an optimistic guess made from an office in Bellingham or Blaine.
Our Process for a Board & Batten Project
- On-site assessment. We look at your home's current siding, sheathing condition, exposure to wind and salt spray, and any moisture or moss issues already visible.
- Detailed estimate. A written scope covering tear-off (if needed), drainage plane and rainscreen approach, flashing details, James Hardie product selection, and ColorPlus color.
- Material staging. Because of the logistics of getting materials onto the peninsula, we plan delivery and staging in advance so your project isn't waiting on a truck.
- Installation to manufacturer spec. Correct fastening, flashing, and batten spacing following James Hardie's published installation requirements — the same requirements that keep the warranty intact.
- Final walkthrough. We go over the finished job with you before we consider it done, not before we leave.
Living With Board & Batten in a Moss-Prone Coastal Climate
Even correctly installed James Hardie siding benefits from a little seasonal attention in an environment like this one. A short annual routine keeps it looking right and catches small issues before they become big ones:
- Rinse the siding with a garden hose once or twice a year, focusing on north-facing walls and areas under eaves where moss tends to establish
- Trim back vegetation and tree branches that shade siding and restrict airflow, since shade and stagnant air are what let moss take hold
- Check caulk joints around windows, doors, and penetrations annually — even good caulk has a service life, and salt air shortens it
- Look at fastener heads and trim edges for early signs of rust bleed or coating wear, especially after winter storms
- Keep gutters clear so overflow doesn't run down the siding face repeatedly in the same spot
None of this is heavy maintenance — it's the kind of once- or twice-a-year check that takes an afternoon and keeps a well-installed job performing the way it's supposed to for decades.
What Affects the Cost of a Board & Batten Project Here
| Factor | Why it matters in Point Roberts |
|---|---|
| Existing siding removal | Tear-off of old material adds labor and disposal logistics that take longer to schedule given limited local access |
| Sheathing and framing condition | Salt air and past moisture intrusion sometimes mean repairs are needed before new siding goes on |
| Home size and wall complexity | More corners, penetrations, and roof lines mean more flashing and batten detail work |
| Material and delivery staging | Getting James Hardie product onto the peninsula efficiently affects scheduling, not just cost |
| Color and trim selection | ColorPlus color options and trim profiles vary in cost and lead time |
We'll walk through all of this with you specifically during an estimate rather than throwing out a number that doesn't reflect your home.
