Blaine Siding Board & Batten Siding Built for Ferndale's Coastal Climate
Ferndale sits close enough to the water that homes here deal with a specific mix of weather stress: salt-laden air drifting in off the Salish Sea, long stretches of driving rain through fall and winter, and a moss season that can run most of the year on shaded north- and west-facing walls. Board and batten siding has a clean, vertical look that a lot of Whatcom County homeowners want, but that look only holds up if the material and the installation are matched to what this climate actually does to a house. We work in Ferndale regularly as part of our Blaine-based service area, and this page covers what board and batten siding needs to perform here, not just look good on installation day.
What Board & Batten Siding Actually Is
Board and batten is a vertical siding style: wide flat boards installed side by side with narrower strips (the "battens") covering the seams between them. It's one of the older siding profiles in American building history, originally developed as a practical way to cover gaps in barn and farmhouse construction, and it's had a long resurgence in modern residential design because of the strong vertical lines it gives a facade.
Why Homeowners Choose It
Most of the homeowners who ask us about board and batten want it for a specific architectural reason — a modern farmhouse look, a clean accent on gables and dormers, or a way to break up a home that's otherwise all horizontal lap siding. It reads as more custom than standard lap siding and pairs well with the kind of Pacific Northwest exterior palettes that are common in Whatcom County right now.
What Whatcom County Weather Demands From Vertical Siding
Vertical siding behaves differently than horizontal lap siding when it comes to water. Lap siding is designed so each course overlaps the one below it, shedding water downward by design. Board and batten relies more heavily on the seams, the battens, and the water-resistive barrier behind the panel doing their job correctly, because water can run straight down a flat board face instead of being broken up by overlapping courses.
Salt Air
Proximity to salt water accelerates corrosion on anything metal — fasteners, flashing, and trim. Siding that looks fine on the surface can fail early if the fasteners holding it in place are rusting from behind.
Driving Rain
Storms coming off the water don't just fall straight down — wind-driven rain pushes water sideways and upward under laps and seams. Vertical siding needs properly detailed joints and a real drainage plane behind it, not just caulk, to handle that kind of weather over years, not just one storm.
Moss and Sustained Moisture
Shaded, north-facing walls in this part of Washington can stay damp for weeks at a time in the fall and winter. Materials that absorb moisture swell, and swelling at board edges is exactly where paint fails first and moss gets a foothold.
Why We Install Only James Hardie Board & Batten
We don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. That's a deliberate standard, not a lack of options. James Hardie's fiber cement is a cement, sand, and cellulose fiber composite — it doesn't absorb water and swell the way wood-based or wood-fiber products can, and it's non-combustible, which matters given the wildfire smoke seasons Western Washington has seen in recent summers.
The Product Line We Use
For board and batten applications, Hardie's vertical panel siding is manufactured with their HZ5 engineered formulation, built specifically for climates like ours — wet winters, humidity, and freeze-thaw swings. It comes with a factory-applied ColorPlus finish, which is baked on under controlled conditions rather than field-painted, giving more consistent color and better fade and moisture resistance at the surface than a site-applied coat.
The Warranty Behind It
Hardie backs their siding with a strong, transferable limited warranty when it's installed to their specifications. That last part matters — the warranty is tied to correct installation, which is a big part of why we treat installation detail as non-negotiable rather than optional upgrades.
What a Correct Board & Batten Installation Involves
Board and batten siding is unforgiving of shortcuts in a way that's not always visible until years later. The difference between a job that lasts and one that fails early usually comes down to details behind the surface, not the boards themselves.
| Detail | Correct Approach | Common Shortcut |
|---|---|---|
| Drainage plane | Rainscreen furring strips create an air gap and drainage path behind the panel | Panel fastened directly to the water-resistive barrier with no gap |
| Fasteners | Corrosion-resistant fasteners at manufacturer-specified spacing and embedment | Standard fasteners, inconsistent spacing, over- or under-driven |
| Flashing | Continuous flashing at windows, doors, and horizontal transitions, integrated with the barrier | Caulk used in place of proper flashing |
| Board and batten joints | Correct gap and fastening pattern per Hardie's published spec, sealed as directed | Boards butted tight or over-caulked to hide gaps |
| Bottom clearance | Proper clearance from grade, decks, and roof lines to keep the bottom edge dry | Siding installed too close to grade or hardscape |
Every one of those "correct approach" items is required to keep a Hardie warranty valid — it's not extra care, it's the baseline.
Our Process for Ferndale Homeowners
- On-site assessment — we look at existing siding, wall condition, moisture history, and how the house is oriented to wind and rain before quoting anything.
- Tear-off and moisture check — old siding comes off and we check the sheathing underneath for hidden rot or water damage before anything new goes up.
- Barrier and drainage plane — water-resistive barrier and rainscreen furring installed correctly, since this is the layer that decides how the wall performs long after the siding itself.
- Flashing and trim — windows, doors, and transitions detailed first, before panels go on around them.
- Board and batten installation — Hardie vertical panels and battens installed to spec, with correct fastening and joint treatment.
- Final walkthrough — we go over the finished work with you directly and cover basic care before we consider the job done.
Why a Crew That Already Works in Ferndale Matters
Siding work isn't identical from one town to the next, even within the same county. A crew that's already worked homes in and around Ferndale and Blaine knows the kind of wall assemblies common to this area, has a realistic sense of what the weather does to a house here across a full year, and isn't guessing at how to sequence a job around this region's rainy stretches. It also means faster response if something needs a look after the fact — a local crew doesn't disappear once the invoice is paid, because Ferndale is part of our regular service area, not a one-off drive.
Maintaining Board & Batten Siding in a Marine Climate
Hardie fiber cement is low-maintenance compared to wood-based alternatives, but "low-maintenance" isn't "no-maintenance," especially this close to salt water.
- Rinse siding once or twice a year to clear salt residue and organic buildup, especially on walls facing prevailing weather.
- Keep gutters and downspouts clear so water isn't sheeting down or pooling against siding.
- Trim back vegetation and tree cover that keeps a wall shaded and damp, since that's where moss and mildew take hold first.
- Inspect caulking at joints, windows, and trim yearly and have gaps resealed before they let water behind the siding.
- Watch for any staining, streaking, or soft spots near the bottom edge, which usually signal a drainage or clearance issue worth checking early.
What Affects the Cost of Board & Batten Siding
Board and batten typically costs somewhat more than standard lap siding installation, mainly because of the batten material and labor and the added flashing detail at every vertical seam. Exact pricing depends on your specific home, but these are the main factors that move the number:
| Factor | Why It Matters |
|---|---|
| Wall complexity | Gables, dormers, and multiple wall planes add cutting, flashing, and labor time |
| Tear-off scope | Removing old siding and repairing any hidden sheathing damage adds time before install even starts |
| Panel and batten selection | Color, texture, and batten width/spacing choices affect material cost |
| Access and site conditions | Multi-story walls, tight lot lines, or difficult staging affect labor and equipment needs |
| Trim and flashing detail | Windows, doors, and transitions on a board and batten wall each need individual flashing work |
A Siding Choice That Should Fit Your House and Your Climate
Board and batten is a strong look for the right home, but in a place like Ferndale, with salt air, driving rain, and a real moss season working against a wall year-round, the material and the installation details matter more than they would somewhere drier and more sheltered. That's the whole reason we standardized on James Hardie rather than offering a menu of vinyl, LP SmartSide, or cedar options — we'd rather install one system correctly and stand behind it than offer several and hope one holds up.
