Ferndale Board & Batten Siding in Kendall: A Look That Needs the Right Material Behind It
Board and batten is one of the most requested siding looks in Whatcom County, and it's easy to see why. The vertical lines read as clean, modern farmhouse, or classic Pacific Northwest depending on the trim details and color, and it works on everything from a small Kendall cabin-style home to a larger custom build. But board and batten is also one of the least forgiving siding profiles when the wrong material or the wrong crew is behind it. The vertical boards and the narrow battens that cover the seams create a lot of joints, a lot of edge grain exposed to weather, and a lot of opportunity for water to find a way in if the installation isn't done with real attention to detail.
For homeowners in Kendall specifically, that matters more than it might in a drier inland climate. This is an area that sees long stretches of wet weather, wind-driven rain off the surrounding valleys and coastal air, and a moss and algae season that can run most of the year on north- and shade-facing walls. A siding style like board and batten, which is chosen for its look, has to also perform, or the look doesn't last.
Kendall's Climate and What It Does to Vertical Siding
Whatcom County sits close enough to the coast that salt-laden air is a real factor, and it combines with the rain patterns typical of this part of Washington to create conditions that are hard on exterior building materials. Board and batten siding, because it's installed vertically with narrow battens covering each seam, has more linear feet of joint per square foot of wall than a standard horizontal lap profile. Every one of those joints is a place where moisture can sit if the material underneath swells, cups, or doesn't shed water the way it's supposed to.
Add in the moss and algae growth that's common on shaded and north-facing elevations in this part of the state, and you have a siding style that needs a material able to hold its shape, hold its paint or factory finish, and resist moisture absorption over years of exposure — not just look good on installation day.
What This Means in Practice
- Battens and board edges are the first place moisture damage shows up on a board and batten wall — they need a material that doesn't swell or split at the edge
- North- and shade-facing walls in Kendall will see moss and algae growth regardless of siding material — the finish needs to hold up to occasional cleaning
- Driving rain means vertical joints need real flashing and drainage planning, not just caulk
- Long wet seasons mean any wood-based product behind the boards needs to dry out between rain events, or trouble starts
Why Board & Batten Needs Fiber Cement, Not Wood or Vinyl
Traditional board and batten was built with solid wood boards and wood battens, and it can still look that way — but wood siding in a climate like Kendall's asks for a level of maintenance most homeowners don't want to sign up for. Wood boards move with moisture, and on a vertical profile with this many seams, that movement shows up as cracking, cupping, and open joints faster than it would on a simpler wall design. Repainting a board and batten wall in solid wood is also more labor-intensive than a flat wall, because of all the battens and edges involved.
Vinyl board and batten avoids the rot problem but brings its own trade-offs. It's a thinner, lighter material that can look noticeably less substantial up close, especially on a style like board and batten where shadow lines and board thickness are part of what makes the look work. Vinyl also expands and contracts significantly with temperature, which on a fastened, gapped profile like this can lead to visible movement over time.
This is why we install James Hardie fiber cement for board and batten projects, full stop. Hardie's vertical siding panels and boards are engineered specifically for this profile — non-combustible, dimensionally stable, and built to hold a factory-applied ColorPlus finish that doesn't rely on the homeowner repainting every few years. It's also thick enough to give board and batten the real shadow-line depth that makes the style look intentional rather than applied.
What Correct Board & Batten Installation Involves
The quality of a board and batten job is almost entirely determined by what happens behind the boards, not the boards themselves. This is a profile where a rushed or corner-cutting install can look fine for a year or two and then start showing problems — usually right at the seams.
Weather Barrier and Drainage Plane
Every board and batten wall needs a continuous weather-resistant barrier behind the siding, installed so water that does get past the boards has somewhere to go rather than sitting against the sheathing. On a vertical profile, this drainage plane is doing more work than it would on horizontal lap siding, because the seams run the same direction as water flow rather than shedding it naturally the way overlapping horizontal boards do.
Batten Spacing and Fastening
Battens need consistent spacing and correct fastener placement to allow the boards underneath room to handle normal seasonal movement without binding or cracking the material at the fastener points. Fastening board and batten too tight, or in the wrong pattern, is one of the most common mistakes made by crews that don't specialize in this profile.
Flashing at Transitions
Windows, doors, corners, and the base of the wall are where board and batten installations most often fail. Correct flashing at every transition — not just caulk — is what keeps driving rain from working its way behind the siding during Kendall's wetter months.
Finish and Caulk Joints
Factory-finished ColorPlus boards reduce the number of field-cut, exposed edges that need sealing, but any cut ends still need to be treated correctly at install, and caulk joints need to be done with a product and technique built to last, not just pass a walk-through inspection.
James Hardie Board & Batten Options
Hardie offers a few different ways to achieve the board and batten look, and the right choice depends on the home's design and the effect you're after.
| Option | Description | Best Fit |
|---|---|---|
| HardiePanel vertical siding with battens | Large-format panels installed vertically with separate battens covering the seams | Modern farmhouse and contemporary designs; fewer seams overall |
| Individual board and batten (engineered boards) | Narrower boards installed with battens over each seam, closer to the traditional look | Homes wanting a more traditional, textured board and batten appearance |
| ColorPlus factory finish | Baked-on finish applied before installation, available across Hardie's color palette | Any homeowner who wants to avoid a repaint cycle |
Our Process for Kendall Homes
We work throughout Whatcom County, and Kendall projects follow the same process we use everywhere, adjusted for the site conditions we find on each specific home.
- On-site assessment of the existing wall assembly, moisture conditions, and any problem areas — particularly on north-facing and tree-shaded walls where moss and trapped moisture are common locally
- Review of board and batten layout options, panel vs. individual board approach, and ColorPlus color selection
- A written estimate with clear scope, no vague allowances
- Removal of old siding and inspection of sheathing for any hidden damage before new material goes on
- Installation of weather barrier, flashing, boards, and battens to manufacturer spec
- Final walkthrough so you understand what was done and what maintenance, if any, the finish will need
Cost Factors for Board & Batten Projects
| Factor | Why It Matters |
|---|---|
| Panel vs. individual board approach | Individual boards mean more material and more labor hours per square foot |
| Wall complexity | Gables, dormers, and multiple transitions all add flashing and cutting time |
| Condition of existing sheathing | Hidden moisture damage found during tear-off can add scope |
| Color and finish selection | Standard ColorPlus colors vs. premium selections can affect material cost |
| Site access | Rural Kendall properties with longer driveways or difficult staging can affect labor time |
Keeping Board & Batten Siding Looking Right in This Climate
- Rinse siding periodically, especially shaded and north-facing walls prone to moss and algae in this climate
- Keep gutters clear so runoff isn't sheeting down wall sections during heavy rain
- Trim back vegetation and tree cover that keeps walls damp and shaded longer than necessary
- Inspect caulk joints at windows, doors, and trim every year or two and have any gaps addressed promptly
- Watch for any battens that seem loose or boards that show movement, and have them checked before the next wet season
Why Hiring a Crew That Already Works Kendall Matters
Board and batten rewards experience. A crew that installs it regularly in Whatcom County knows how the local wind and rain patterns tend to hit vertical siding, where moss problems typically start, and how to detail flashing so it holds up through this area's wet season rather than just passing a first-year inspection. That local, repeat experience is worth more on this profile than on almost any other siding style, because so much of the long-term performance comes down to details that aren't visible once the job is finished.
We install James Hardie fiber cement exclusively because we've seen what holds up in this climate and what doesn't, and board and batten is a style where that decision matters even more than usual. If you're considering board and batten for a home in Kendall, we're happy to come take a look and put together a straightforward, no-pressure estimate — no obligation, just an honest read on your project.
