Board & Batten Siding for Columbia, Fairhaven
Board and batten is one of the most requested siding profiles in the Columbia area, and it's easy to see why. The vertical lines suit the mix of craftsman cottages, updated bungalows, and newer infill homes you'll find on the streets between downtown Fairhaven and the waterfront. It reads as clean and a little more architectural than standard lap siding, without looking out of place next to the neighborhood's older housing stock.
What doesn't get talked about enough is that board and batten is also one of the least forgiving profiles to install badly. The vertical battens create dozens of extra joints and fastening points compared to horizontal lap siding, and every one of those joints is a potential water path. In a climate like Whatcom County's — salt air off Bellingham Bay, driving rain that comes in sideways off the water, and a moss season that runs most of the year — a board and batten job that isn't detailed correctly will show problems faster than almost any other siding style.
This page is specifically about doing board and batten right for homes in Columbia and the immediate Fairhaven area. It's not a general overview of the style — it's what we've learned installing it on homes exposed to this particular stretch of coastline.

What Columbia's Climate Actually Does to This Siding Style
Salt Air and Corrosion
Homes within a mile or two of Bellingham Bay take on airborne salt, even without a direct water view. Salt accelerates corrosion on fasteners, flashing, and any exposed metal trim. On a board and batten wall, the batten strips themselves are typically face-nailed or blind-nailed at close intervals, which means there are simply more fasteners exposed to that salt-laden air than on a standard lap wall. Fastener choice and fastener coverage (caulked, capped, or concealed) matter more here than they would fifty miles inland.
Driving Rain and Water Management
Fairhaven sits in a pattern where wind-driven rain off the Strait and the bay hits west- and south-facing walls hard, often for days at a stretch during the fall and winter storm cycle. Vertical battens create a series of narrow channels running down the wall. If those channels aren't backed by a proper drainage plane, water can wick behind the battens and sit against the sheathing instead of running off. This is the single most common failure point we see on board and batten walls that weren't detailed for a wet coastal climate.
Moss, Algae, and Prolonged Shade
Whatcom County's long damp season and the tree cover common in Columbia's older lots mean moss and algae growth is a near-constant battle on north- and east-facing walls. Vertical siding sheds standing water better than most horizontal profiles when it's detailed correctly, but the battens themselves create small horizontal ledges at their base where debris and moisture can collect if the installer didn't account for it.
Why We Install This Look in James Hardie Only
We install James Hardie fiber cement exclusively — we don't offer board and batten in vinyl, LP SmartSide, primed spruce, cedar, or other fiber cement brands like Cemplank or Allura. For a profile with this many joints and this much fastener exposure, the product decision matters even more than it does for standard lap siding.
Fiber cement doesn't rot, swell, or delaminate the way engineered wood products can when moisture gets past a joint. It's non-combustible, which matters to insurers and to homeowners who've watched wildfire smoke drift into the region in recent summers. And James Hardie's ColorPlus finish is baked on at the factory under conditions a job-site paint or stain application can't match — which matters most on a style like board and batten, where the battens and gaps create dozens of exposed edges that would otherwise need to be field-painted and re-painted on a regular cycle.
We're not going to pretend other products are worthless — vinyl board and batten is inexpensive and LP SmartSide has real fans. But we've made a professional decision not to install them, because in a climate that stacks salt air, driving rain, and moss season on top of each other, we don't want our name on a wall that depends on a homeowner staying ahead of caulk and paint maintenance to keep water out. Hardie is engineered for exactly this kind of exposure, and it's what we put on Columbia homes.
What a Correct Board & Batten Installation Actually Involves
Rainscreen and Drainage Plane
Before the first panel goes up, the wall needs a water-resistive barrier and, ideally, a furring or rainscreen gap behind the siding. This gap lets any water that does get behind the cladding drain and dry instead of sitting against the sheathing. On a vertical batten wall in a wet coastal climate, we treat this as non-negotiable, not an upgrade.
Panel Layout, Spacing, and Fastening
Hardie board and batten can be done as individual vertical panels with battens over the seams, or as a panel-and-batten system depending on the look and budget. Either way, panel spacing, fastener placement, and batten width need to follow James Hardie's published fastening schedule for our wind and exposure zone — not a generic spacing pulled from a different climate's install guide.
Joints, Flashing, and Trim
Every horizontal joint (where panels stop and start vertically), every window and door head, and every outside corner needs proper flashing and either a shadow-gap detail or sealant joint that's actually rated for the movement and exposure. This is where rushed jobs fail first — a missed head flashing above a window on a west-facing wall will show a stain within a season or two in this climate.
Fastener and Trim Details Checklist
- Corrosion-resistant fasteners rated for coastal/marine exposure, not standard interior-grade nails or screws
- Continuous water-resistive barrier with all seams and penetrations properly lapped and taped
- Furring strips or a rainscreen product creating a drainage gap behind the battens
- Z-flashing or head flashing over every window, door, and horizontal panel joint
- Batten spacing and fastener schedule matching the manufacturer's spec for our wind exposure
- Factory-finished ColorPlus edges sealed per Hardie's install guide at cut ends
Our Process for Columbia-Area Projects
We keep the process straightforward because most of what determines a good outcome happens before the first panel is cut.
- On-site walkthrough — we look at wall exposure, existing sheathing and moisture barrier condition, tree cover, and any current signs of moss, staining, or trapped moisture.
- Scope and product selection — we confirm the board and batten layout (panel width, batten spacing, reveal) against the home's style and your preferences, and spec the James Hardie products and ColorPlus color for the job.
- Prep and tear-off — removal of old siding where needed, sheathing repair, and installation of the water-resistive barrier and drainage gap.
- Installation — panels and battens installed to spec, with flashing and trim detailed at every joint, window, and corner.
- Final walkthrough — we go over the finished wall with you, joint by joint, before we consider the job done.
Board & Batten in James Hardie vs. Other Approaches
| Approach | How It Handles Salt Air & Driving Rain | Maintenance Burden Locally |
|---|---|---|
| James Hardie fiber cement (our install) | Non-combustible, factory-finished, engineered for coastal exposure with proper drainage detailing | Occasional wash-down; repaint cycle is decades out, not years |
| Vinyl board and batten | Won't rot, but can warp or crack in temperature swings and doesn't manage a rainscreen the same way | Low, but color fades and panels can loosen over time |
| LP SmartSide / engineered wood | Vulnerable at cut edges and joints if moisture gets in; more joints on board and batten means more exposure points | Requires diligent caulk and finish maintenance to stay ahead of moisture |
| Cedar or primed spruce | Handles moisture better than engineered wood when maintained, but the marine layer and moss season accelerate weathering | Highest — regular refinishing, staining, and moss/algae treatment |
This isn't a claim that the other products fail outright — plenty of homes carry them without issue. It's why, given this climate and given how many joints a board and batten wall has, we standardized on the one system we're confident holds up here with the least ongoing maintenance asked of the homeowner.
Why a Crew That Already Works Columbia Matters
Board and batten installation isn't something you learn once and apply the same way everywhere. A crew that regularly works Columbia and the surrounding Fairhaven neighborhoods already knows which walls take the worst of the wind-driven rain, how much moss pressure to expect on shaded north sides, and how the area's older homes are typically framed and sheathed, which affects how we approach tear-off and prep. That local repetition shows up in the details — the flashing choices, the fastener spacing, the drainage gap — that separate a board and batten wall that looks good for two years from one that looks good for twenty.
It also matters for permitting and for working around the kind of older construction common in this part of Fairhaven, where sheathing condition and wall assemblies can vary quite a bit from house to house. A crew unfamiliar with the area is guessing at these things. A local crew has already seen them.
Keeping a Board & Batten Wall Looking Right in This Climate
- Rinse pollen, salt residue, and road grime off the wall once or twice a year with a garden hose — avoid high-pressure washing directly into joints
- Trim back vegetation and tree limbs that keep a wall in constant shade, since that's where moss takes hold fastest
- Walk the exterior after major fall or winter storms and note any new staining below joints or window heads
- Keep gutters and downspouts clear so roof runoff isn't dumping extra water onto siding below
- Have caulked joints and trim checked periodically — even with Hardie's low-maintenance profile, sealant at trim joints has a service life
