Birch Bay Board & Batten Siding for Cherry Point Homes
Cherry Point sits on one of the more exposed stretches of the Whatcom County coastline, and homes out here take a different kind of beating than houses ten miles inland. Salt-laden air off the water, wind-driven rain that comes in sideways during winter storms, and a moss season that can run eight months out of the year all put real stress on exterior siding. Board and batten is a popular choice for the look homeowners want in this area — clean vertical lines, a farmhouse or modern-coastal feel — but the product underneath that look matters more here than almost anywhere else in the county.
We install board and batten siding for Cherry Point properties using James Hardie fiber cement exclusively. This page walks through what the climate actually does to siding out here, what a correctly built board and batten system looks like, and how we approach jobs in this specific area.
What Cherry Point's Climate Does to Siding
Salt Air and Corrosion
Proximity to the water means airborne salt settles on every exterior surface, including siding, fasteners, and trim. Salt is corrosive to exposed metal and accelerates the breakdown of some coatings and adhesives over time. It's a slow, cumulative process — you don't see damage in year one, you see it in year eight or ten if the wrong materials were used.
Wind-Driven Rain
Open exposure to wind off the water means rain doesn't just fall on Cherry Point homes, it gets driven horizontally into wall assemblies, especially around board and batten seams and vertical joints if they weren't detailed correctly. Any siding product that swells, wicks moisture, or relies heavily on paint film integrity to stay sealed is going to struggle with this pattern of exposure.
Moss and Sustained Moisture
Whatcom County's long, wet shoulder seasons keep exterior surfaces damp for extended stretches, and shaded or north-facing walls in particular grow moss and algae if the siding surface holds moisture. Moss isn't just cosmetic — where it takes hold, it keeps the substrate underneath wetter for longer, which matters a lot if that substrate is wood-based.
Why Board & Batten Specifically Needs the Right Material Here
Board and batten relies on vertical boards and narrow battens covering the seams between them. That means more linear feet of seams and joints per square foot of wall than a typical horizontal lap job — more edges, more fastener points, more places where water can find a way in if the material or the installation isn't right. In a climate like Cherry Point's, that raises the stakes on two things:
- Dimensional stability — the boards and battens need to hold their size and shape wet or dry, summer or winter, or the reveals and joints start to gap or bind
- Moisture tolerance at the substrate level — the board material itself has to resist rot and moisture damage, not just the paint on top of it
This is exactly where board and batten made from wood-based products — primed spruce, cedar, or engineered wood siding — runs into trouble on an exposed coastal site. Wood-based substrates can swell, cup, or start to break down at cut edges and joints when they take on repeated moisture, even with a good factory coating. On a home with a lot of seams, that's a lot of vulnerable edges. We don't install those products for board and batten applications, full stop — not because they're bad products in every setting, but because Cherry Point's exposure is exactly the kind of environment where their weaknesses show up fastest.
Why We Install James Hardie for This Application
James Hardie fiber cement is what we use for every board and batten project we build in Cherry Point, and it's not a marketing preference — it's a materials decision based on what actually holds up here.
Non-Combustible and Dimensionally Stable
Fiber cement doesn't expand and contract with moisture the way wood-based products do, which keeps board and batten reveals tight and consistent year-round instead of gapping in dry summers and swelling in wet winters.
ColorPlus Factory Finish
Hardie's ColorPlus finish is baked on at the factory under controlled conditions, which gives it better adhesion and UV resistance than field-applied paint — and it means the color holds up under salt air exposure without the chalking and fading that field-painted surfaces can show sooner in this environment.
HZ5 Engineering for This Climate
James Hardie makes climate-specific product lines, and the HZ5 formulation is engineered for the freeze-thaw cycles, moisture, and marine exposure typical of Pacific Northwest coastal zones — which describes Cherry Point about as precisely as it describes anywhere in the county.
Moss and Algae Resistance
Because fiber cement doesn't provide the same organic material for moss and algae to root into that wood-based sidings can, and because the ColorPlus coating sheds water rather than absorbing it, Hardie board and batten holds up better through Whatcom County's long moss season with less staining and less surface breakdown.
Warranty Backing
James Hardie backs its siding with a strong, transferable limited warranty, which matters on a coastal property where buyers and future owners will want documentation that the exterior was built to last in this specific climate.
What a Correct Board & Batten Installation Involves
The material is half the equation. The other half is installation detail, and on an exposed site like Cherry Point, the details matter more than usual.
- Proper weather-resistive barrier and rainscreen or drainage plane behind the siding, so any water that does get past the surface has somewhere to go
- Correct fastener type and spacing — stainless or coated fasteners rated for coastal/marine exposure, not standard fasteners that corrode faster in salt air
- Batten spacing and fastening per Hardie's engineering specs, not "close enough" spacing that looks fine but doesn't perform
- Proper flashing at every horizontal transition — window heads, trim boards, roof-to-wall intersections — since these are the spots wind-driven rain finds first
- Field-cut edges primed or sealed per manufacturer instructions before installation, so exposed cut ends aren't left vulnerable
- Correct clearance from grade, decks, and roof lines to keep the bottom of the siding out of standing moisture
Skipping any one of these on a coastal job tends to show up as a callback a few years later, not immediately — which is part of why the installer's experience with this specific type of exposure matters as much as the product choice.
Board & Batten vs. Other Siding Profiles for Cherry Point Homes
| Factor | Board & Batten (Hardie) | Horizontal Lap (Hardie) |
|---|---|---|
| Visual style | Vertical, farmhouse/modern-coastal look | Traditional horizontal reveal |
| Seam count | Higher — more vertical joints to detail correctly | Lower — fewer joints per wall |
| Best fit | Accent walls, gables, full-home vertical statement | Whole-home standard application |
| Install sensitivity to coastal exposure | Higher — batten fastening and flashing detail is critical | Moderate — standard lap detailing applies |
| Maintenance in moss season | Low, with ColorPlus finish | Low, with ColorPlus finish |
Both profiles perform well in fiber cement — the choice usually comes down to the look a homeowner wants, or whether board and batten is being used as a full-home siding or as an accent on gables and entry features alongside lap siding elsewhere on the house.
Our Process for Cherry Point Board & Batten Projects
- On-site assessment of wall exposure, moisture history, and existing siding condition, with particular attention to which elevations take the most wind-driven rain
- Product and reveal recommendation — board width, batten spacing, and HZ5 or standard HZ product selection based on the site
- Removal of failing siding and inspection of sheathing for any moisture damage that needs addressing before new siding goes on
- Installation of weather-resistive barrier, drainage plane, and flashing details built for coastal exposure
- Board and batten installation to Hardie's fastening and spacing specifications
- Final walkthrough covering care and what to watch for through the first few wet seasons
Why Local Experience with This Coastline Matters
A crew that mostly builds inland doesn't always plan for wind-driven rain the way a Cherry Point job requires. Fastener corrosion resistance, drainage plane detailing, and flashing at horizontal transitions are the parts of a board and batten install that separate a job that looks good for two years from one that performs for twenty. We work this stretch of Whatcom County regularly, which means we're not guessing at how exposed a given wall is or what kind of moisture load it's going to see — we're building to what we've already seen hold up, and what hasn't, on homes with the same salt air and rain exposure as yours.
