Blaine Siding Why Board & Batten Needs Extra Thought in Cherry Point
Cherry Point sits right up against the water on Blaine's western edge, and that location changes what siding has to survive. Homes here take wind and moisture straight off the Strait of Georgia, with less tree buffer than properties further inland in Whatcom County. Board & batten siding — with its vertical boards and raised battens covering the seams — has become popular for the clean, farmhouse-adjacent look it gives rural and waterfront properties. It's a good match for the character of this area. But vertical siding also behaves differently than horizontal lap siding when water is involved, and in a spot like Cherry Point, that difference matters more than it would in a sheltered subdivision a few miles inland.
This page is specifically about board & batten siding for Cherry Point homes — not a general overview of the style. If you're weighing this look for a property out here, the climate exposure and installation details below are what actually determine whether it holds up or becomes a maintenance headache.
What Board & Batten Siding Is
Board & batten is a vertical siding pattern: wide flat panels or boards installed vertically, with narrow strips (battens) covering the seams between them. It reads as more modern-farmhouse or agricultural than traditional horizontal lap siding, and it's often used as a full exterior treatment or mixed with lap siding as an accent on gables, dormers, or entry features. On rural and semi-rural Cherry Point lots, it tends to suit the property better than a purely suburban lap-siding look — a lot of homes out here have some acreage, outbuildings, or a farmhouse-style build to begin with.
The style itself isn't the hard part. The hard part is what's underneath it, because vertical siding creates different water paths than horizontal siding does, and Cherry Point's exposure doesn't forgive shortcuts.
How Salt Air, Driving Rain, and Moss Season Attack Vertical Siding
Salt Air and Fastener Corrosion
Airborne salt off the water accelerates corrosion on anything metal — fasteners, flashing, trim screws. On board & batten, the batten strips are fastened directly through the joints between boards, which means there are more exposed fastener heads per square foot than on lap siding. If those fasteners aren't rated for coastal exposure, they'll rust years before the siding itself shows any wear, and rust streaks bleeding down painted fiber cement are one of the most common early failures we see on properties this close to the water.
Wind-Driven Rain
Cherry Point catches wind straight off open water with little to break it up, which pushes rain sideways and upward into seams that would stay dry on a more sheltered inland lot. Board & batten has vertical seams running the full height of the wall — if those seams aren't backed by a proper drainage plane, wind-driven rain will find its way behind the siding. Once moisture gets behind vertical siding, it has a straight vertical path down the wall, which is a different failure pattern than horizontal siding traps.
Moss Season
Whatcom County's long wet season keeps north-facing and shaded walls damp for months at a time, and vertical battens create horizontal ledges — however narrow — where moisture, needles, and organic debris can sit. On a rural Cherry Point lot with mature trees or hedgerows shading part of the house, that adds up to more moss and mildew pressure on those surfaces than a homeowner would see on an open, sunnier elevation.
What a Correct Board & Batten Installation Involves
None of the issues above are reasons to avoid board & batten on a Cherry Point home. They're reasons the installation has to be built for this exposure, not just for the look. A correct job includes:
- A continuous weather-resistive barrier behind the siding, lapped and taped correctly at every seam and penetration
- A rainscreen gap (vertical furring strips) that lets any water that does get past the siding drain and dry out instead of sitting against the wall sheathing
- Corrosion-resistant fasteners rated for coastal/marine exposure — not standard interior-grade fasteners
- Flashing at every horizontal transition: window and door heads, trim boards, roof-to-wall intersections, and the base of the wall
- Correct board and batten spacing and fastening pattern per manufacturer specification, not "close enough"
- Factory-finished fiber cement (James Hardie ColorPlus) rather than field-painted boards, so the finish itself resists moss growth and UV fading consistently across every board
James Hardie makes board & batten achievable a couple of ways — HardiePanel vertical siding with HardieTrim battens over the seams, or individual HardiePlank-style boards installed vertically with battens between them. Either approach uses Hardie's HZ5 product line, engineered for wetter, harsher climates like the Pacific Northwest, which is the right baseline for anything installed this close to open water.
Material Comparison for Coastal Whatcom County Properties
Board & batten is available in more than one material, and the differences matter more on an exposed Cherry Point lot than they would somewhere sheltered. This is why we install James Hardie fiber cement exclusively and don't offer vinyl, LP SmartSide, or unfinished cedar board & batten.
| Material | Salt Air / Corrosion Behavior | Moisture Resistance | Maintenance in This Climate |
|---|---|---|---|
| James Hardie fiber cement | Non-combustible, doesn't corrode; factory finish resists coastal wear | Engineered HZ5 formulation for wet Pacific Northwest exposure | Periodic wash; ColorPlus finish holds color without repainting on Hardie's schedule |
| Cedar (unfinished or primed) | No corrosion, but absorbs moisture and salt-laden air readily | Prone to swelling, cupping, and rot without diligent upkeep | Regular refinishing/staining; higher upkeep near water |
| Vinyl board & batten | Won't rust, but can become brittle and crack in wind-driven debris | Seams and J-channels can trap moisture behind panels | Low upkeep but limited repairability and shorter realistic lifespan |
| LP SmartSide | Engineered wood substrate; edges and cut ends need diligent sealing near salt air | Vulnerable at unsealed cuts and fastener penetrations | Requires careful field maintenance to protect exposed wood fiber |
Cost Factors for Cherry Point Board & Batten Projects
Every property is different, so we don't quote off a page — but these are the factors that actually move the price on a board & batten job out here:
| Factor | Why It Matters |
|---|---|
| Wall height and gable complexity | More cuts, more flashing detail, more labor per square foot |
| Full-house vs. accent application | Board & batten as a gable or entry accent costs less than a full exterior |
| Existing wall condition | Sheathing repair or added rainscreen framing adds time before siding goes up |
| Trim and window detail count | Each opening needs correct flashing, which adds labor beyond flat wall area |
| Access and site conditions | Rural Cherry Point lots sometimes need more setup for equipment and material staging |
Our Process, Start to Finish
We walk the property first and look at exposure specifically — which walls take the brunt of wind off the water, where moss and shading are already a problem, and where the current siding (if any) shows early failure. From there we plan the weather-resistive barrier and rainscreen approach for that specific wall, not a generic spec. Installation follows James Hardie's fastening and clearance requirements to the letter, including ground clearance and roof-line clearance, both of which keep moisture away from the bottom and top edges of the siding long-term. We finish with a walk-through so you know exactly what was installed and what, if anything, needs periodic attention.
Why Hiring a Crew That Already Works Cherry Point Matters
A contractor who mostly works sheltered, inland neighborhoods can install board & batten correctly by the book and still miss the details that matter specifically out here — coastal-rated fasteners, rainscreen detailing sized for wind-driven rain, and awareness of which elevations on a given lot take the worst of the exposure. We work Blaine and the surrounding Whatcom County coastline regularly, which means we're not guessing at how Cherry Point's exposure should change the installation — we're building for it from the first nail.
Maintenance Checklist for Board & Batten Homes Near the Water
Correct installation does most of the work, but a little seasonal attention keeps board & batten siding performing for decades in this climate:
- Rinse salt residue and debris off the siding a couple of times a year, especially on water-facing walls
- Check caulking at window and door trim annually and re-seal any cracked joints promptly
- Watch shaded or north-facing walls for early moss growth and clean it off before it spreads
- Keep gutters and downspouts clear so roof runoff isn't sheeting down the siding
- Trim back vegetation that keeps any wall section damp or shaded longer than necessary
- Have fastener heads and flashing points inspected every few years for early corrosion signs
