Blaine Why Point Roberts Needs Board & Batten Done Right
Point Roberts sits on a peninsula bounded by water on three sides, which means homes here take on a level of salt air exposure that most of Whatcom County never sees. Add the wind-driven rain that comes off Boundary Bay and the Strait of Georgia, plus a moss season that can run from fall through spring in the Pacific Northwest, and you have an exterior envelope working overtime year-round. Board and batten siding is a popular choice for the area's cabins, cottages, and newer builds because of its clean, vertical look, but that same batten-and-seam design creates more joints and more opportunities for water to find a way in if the material or the installation isn't up to the job.
We install board and batten siding throughout the Blaine area, and Point Roberts is part of our regular service territory, not an occasional trip. That matters more than it sounds like it should, because this style of siding rewards precision and punishes shortcuts, and a crew that understands the local exposure builds differently than one that doesn't.
What Board and Batten Siding Actually Is
Board and batten is a vertical siding pattern: wide flat panels or boards installed side by side, with narrower strips (the battens) covering the seams between them. It's one of the oldest siding styles in North America, originally developed as a practical way to cover gaps between rough-sawn boards on barns and farmhouses. Today it's chosen mostly for its look — clean vertical lines, strong shadow lines from the battens, and a style that reads as both rustic and modern depending on the color and trim details around it.
The style works on a full elevation or as an accent — a gable end, a porch surround, a dormer — paired with horizontal lap siding elsewhere on the house. On Point Roberts we see it used both ways: full board and batten on smaller cottage-style homes, and as an accent feature on larger builds.
The Climate Problem With Board and Batten
The vertical seams and batten strips that give this style its look are also its weak point if the wrong material or installation method is used. Every seam is a place where water can get behind the cladding, and in a marine environment like Point Roberts, that water carries salt. Salt air accelerates corrosion of fasteners and metal flashing, and it keeps painted surfaces damp longer than drier inland climates do — which is exactly the condition moss and mildew need to take hold.
This is why board and batten siding has a mixed reputation among contractors. Done with the wrong product or without proper drainage behind it, it traps moisture at every batten and seam. Done correctly, with a material engineered for wet climates and a proper rainscreen gap behind the panels, it holds up as well as any siding style available.
What goes wrong with a poor installation
- Battens face-nailed directly through both boards without expansion room, causing splitting and cracked caulk joints within a few seasons
- No rainscreen gap, so any water that gets behind a seam has nowhere to drain or dry
- Butt joints and corners sealed with caulk instead of proper flashing, which fails long before the siding does
- Materials not rated for direct coastal exposure, leading to swelling, delamination, or paint failure
- Fasteners that aren't corrosion-resistant, which rust and stain the face of the siding within a few years in salt air
Why We Only Install James Hardie Board and Batten
We standardized on James Hardie fiber cement for every siding job we take on, and board and batten is no exception. Hardie's vertical siding panels are engineered fiber cement — not wood, not a wood composite — which means they don't absorb water the way primed spruce or cedar boards can, and they won't delaminate the way some engineered wood products can when a seam stays wet too long. Paired with Hardie trim battens and a factory ColorPlus finish, you get a board and batten look that's baked to hold color instead of relying on a field-applied paint job to do all the work in a wet, salty climate.
We don't install vinyl board and batten, engineered wood panels, or primed wood board and batten. Those products have their place and their own manufacturers stand behind them, but we've made a professional decision to put James Hardie on every home we side, because in a marine environment like Point Roberts the trade-offs of those other materials — moisture sensitivity, shorter paint cycles, more demanding maintenance — aren't ones we're willing to install and then hand the homeowner the bill for later. Hardie's HZ5 product line is engineered specifically for climates with prolonged moisture exposure, which describes this stretch of the Washington coast well.
What Correct Installation Involves
Board and batten looks simple from the outside — vertical boards, strips over the seams — but a correct installation has several layers most homeowners never see.
Behind the siding
- A weather-resistant barrier installed shingle-style so every layer drains down and out, never trapping water behind it
- A rainscreen gap (typically furring strips) between the barrier and the siding, so any moisture that does get behind a seam has room to drain and air to dry it out
- Properly integrated flashing at every window, door, and roofline intersection — the majority of siding failures we're called to repair start at a poorly flashed penetration, not the field of the siding itself
The siding itself
- Hardie vertical panels installed with the manufacturer-specified fastener spacing and gapping, so the material can move slightly with temperature and moisture changes without cracking
- Battens installed with the correct nailing pattern — through one layer with float room on the other, not pinned tight on both sides
- Corrosion-resistant fasteners rated for coastal exposure, not standard interior-grade nails or screws
- Factory-finished ColorPlus panels wherever possible, which cuts down on field caulking and touch-up painting that has to be redone every few years
Our Process for Point Roberts Homes
Point Roberts is geographically part of Whatcom County but physically separated from the rest of Blaine and the mainland — reaching it means crossing an international border in each direction. We plan our Point Roberts projects around that reality rather than treating it as an afterthought: material deliveries, crew scheduling, and equipment logistics are all planned in advance so a job doesn't stall out waiting on a border crossing or a missed delivery window. A crew that only occasionally works out there is learning that logistics on your project's schedule. We've already worked it out.
On every board and batten project, our process looks like this:
- On-site evaluation of the existing wall assembly, drainage, and any moisture damage from the current siding
- A written estimate that spells out the Hardie products, colors, and trim details being used — no vague allowances
- Removal of old siding and inspection of the sheathing underneath, with any rot or damage addressed before new material goes up
- Installation of the weather barrier, rainscreen, and flashing package appropriate to a marine climate
- Hardie panel and batten installation to manufacturer specification
- Final walkthrough and warranty paperwork, including both the manufacturer warranty and our installation workmanship warranty
Cost Factors for Board and Batten in a Coastal Climate
Board and batten costs vary by home size, existing wall condition, and how much trim and detail work the job requires. The table below covers the main factors that move the price up or down, without pinning a number to your specific project — every home is different, and the only way to get an accurate figure is a walkthrough.
| Factor | Why It Matters |
|---|---|
| Wall condition underneath old siding | Rot or moisture damage found during tear-off adds repair scope before new siding can go on |
| Full elevation vs. accent use | Full-home board and batten costs more than using it as a gable or feature accent over lap siding |
| Rainscreen and flashing detail | A proper drainage assembly behind the siding adds labor but is the single biggest factor in long-term performance here |
| Trim and corner complexity | Multiple gables, dormers, and window trim add labor time versus a simple rectangular wall |
| ColorPlus vs. field-painted finish | Factory finish costs more up front but removes a recurring repaint cost down the road |
Maintaining Board and Batten in This Climate
Even the right material benefits from a little seasonal attention in a marine environment. A short annual routine goes a long way toward protecting the investment:
- Rinse salt residue off the siding once or twice a year, especially on elevations facing open water
- Check caulking at window and door trim annually for cracking or gaps, and have it renewed before it fails, not after
- Keep gutters and downspouts clear so runoff isn't sheeting down the face of the siding during heavy rain
- Trim back vegetation and tree cover that keeps siding shaded and damp longer than the rest of the house — a leading contributor to moss growth
- Have flashing at roof-to-wall intersections inspected every few years, since these are the most common points of hidden water intrusion
Why Hiring Local Experience Matters
Board and batten in a coastal Whatcom County climate is not the same project as board and batten in a dry inland town, even though the finished product looks identical from the street. The wall assembly behind it, the fasteners used, the flashing detail at every seam, and the maintenance schedule afterward all need to account for salt air and sustained wet weather. A crew that already works Point Roberts and the greater Blaine area on a regular basis has already made the mistakes and corrected for them — you shouldn't be the one paying for that education on your own home.
If you're considering board and batten siding for a home in Point Roberts, we're glad to come take a look, walk the exterior with you, and put together a straightforward, no-pressure estimate using James Hardie fiber cement siding — the only product we install and stand behind.
