Ferndale Siding Board & Batten in Cordata: A Style That Works With the Climate
Board and batten has become one of the most requested siding styles for homes in and around Cordata, and it's not just about the look. The vertical boards and raised battens read as clean, modern, or classic farmhouse depending on trim and color choices, which is why we see it on everything from newer builds to remodels of older ranch-style homes. But in Whatcom County, a siding style has to earn its place on the wall by handling weather, not just photographing well.
This page is specifically about board and batten siding for homes in the Cordata area. If you're comparing it to lap siding generally, or you're not sure board and batten is the right fit for your house, that's a broader conversation — this one assumes you already like the look and want to know what it takes to do it right here.
What Driving Rain, Salt Air, and Moss Do to Vertical Siding
Vertical siding behaves differently than horizontal lap siding in wet weather, and that matters a lot in this part of Washington. Board and batten relies on seams running up and down the wall rather than overlapping courses shedding water downward the way lap siding does. Done correctly, with the right drainage plane and flashing behind those seams, that's not a problem. Done poorly, it's exactly where water finds its way in.
A few things about our local climate make this worth taking seriously:
- Driving rain: Wind-driven rain doesn't just run down a wall — it pushes sideways and can work into vertical seams and batten joints if they aren't properly lapped, caulked, or backed with a drainage gap.
- Salt air: Proximity to Puget Sound and Bellingham Bay means airborne salt accelerates corrosion on exposed fasteners and lower-grade trim, and it degrades some paint and coating systems faster than inland environments do.
- Long moss season: Cool, damp, shaded conditions for much of the year give moss and algae plenty of time to establish on siding that stays wet, especially on north-facing walls or under tree cover.
None of that means board and batten is a bad choice here — it means the material and the installation details have to be matched to the conditions, not just picked for appearance.
What a Correct Board & Batten Installation Actually Involves
Drainage Behind the Battens
The single biggest difference between board and batten siding that lasts and board and batten siding that fails is what's happening behind it. A proper installation includes a weather-resistant barrier and, in most cases, a furring or drainage gap so that any moisture that does get past the surface can drain and dry out instead of sitting against sheathing.
Fasteners, Flashing, and Joints
Every seam, corner, window, and door opening needs correct flashing so water is directed out and down, never trapped behind the cladding. Fasteners need to be corrosion-resistant and set at the manufacturer's specified pattern — this is one of the areas where salt-air exposure punishes shortcuts, since the wrong fastener can start staining or failing years before the siding itself would.
Batten Spacing and Panel Layout
Batten spacing isn't just aesthetic. Panels and battens need consistent, code-compliant fastening and spacing that accounts for expansion and contraction, especially through our seasonal swings between soggy winters and drier summer stretches.
When any one of these details is skipped, the siding can look fine for a year or two and then start showing problems — staining at seams, soft spots at the bottom courses, or paint failure around fasteners — that are expensive to trace back and fix once they're hidden behind finished walls.
James Hardie Board & Batten: The System We Install
We install James Hardie fiber cement exclusively — not vinyl board and batten, not LP SmartSide, not primed spruce or cedar board and batten. That's a deliberate standard, not a sales preference, and it applies to every job we take on, including board and batten for Cordata homes.
Why Fiber Cement for This Style
Board and batten puts more vertical seam length on a wall than most lap siding profiles, which means moisture management and material stability matter more, not less. James Hardie's fiber cement panels are non-combustible, dimensionally stable across our wet winters and drier summers, and engineered specifically for Pacific Northwest moisture exposure through Hardie's HZ5 product line.
ColorPlus Factory Finish
James Hardie's ColorPlus finish is baked on at the factory under controlled conditions, which gives it better fade and moisture resistance than field-applied paint, along with a stronger warranty on the finish itself. In a climate where UV exposure and salt air both work against paint over time, that factory-cured finish is a real, practical advantage — not a marketing detail.
We've made the call not to install vinyl or engineered-wood board and batten because we've seen how the maintenance burden and moisture sensitivity of those materials play out over years in this climate, not over a single install season. Vinyl can warp or fade and doesn't hold paint well if you ever want to change the color. Engineered wood products depend heavily on maintaining an intact factory coating and diligent caulking to keep moisture out at the edges. James Hardie's fiber cement gives us a product we're confident standing behind long after the crew leaves.
Our Process on a Cordata Board & Batten Project
- Assessment: We walk the exterior, check existing sheathing and framing condition, and note drainage, sun exposure, and any moss or moisture history on the walls.
- Tear-off or overlay decision: Depending on what's currently on the house and its condition, we determine whether a full tear-off to bare sheathing is needed or whether the existing wall system supports a direct re-side.
- Weather barrier and drainage plane: We install or verify the water-resistive barrier and drainage gap before a single board goes up.
- Flashing at every penetration: Windows, doors, and any wall penetrations get flashed before the siding closes over them.
- Panel and batten installation: James Hardie panels and battens go up per manufacturer spec, with correct fastener type, spacing, and joint treatment.
- Trim, caulking, and final inspection: Trim details are finished, joints are sealed where specified, and we walk the completed job before calling it done.
Every step matters, but the steps you can't see once the siding is up — the barrier, the flashing, the drainage gap — are the ones that determine whether the finished product holds up through Whatcom County winters.
Cost Factors for Board & Batten Siding
Board and batten costs vary by project, and we won't quote a number without seeing the house. What we can do is explain what actually drives the price up or down, so you know what you're evaluating when you get quotes.
| Factor | Why It Affects Cost |
|---|---|
| Tear-off vs. overlay | Removing old siding down to sheathing costs more upfront but is often necessary to install drainage and barrier systems correctly |
| Wall height and access | Two-story walls, steep grades, or limited access add labor time and equipment needs |
| Trim and detail complexity | Homes with more corners, window trim, and architectural detail take more time to flash and finish correctly |
| Sheathing or framing repair | Any rot or damage found once old siding comes off needs to be repaired before new siding goes on |
| Batten spacing and reveal | Tighter batten spacing uses more material and labor than wider spacing |
The honest answer on price is that a correct board and batten job costs more than a corner-cut one, mostly because of labor — the material difference between doing the drainage and flashing details right versus skipping them is small compared to the labor time involved.
Keeping Board & Batten Siding Healthy Year-Round
Fiber cement siding is low-maintenance compared to wood, but "low-maintenance" doesn't mean "no maintenance," especially with our moss season and the amount of rain Whatcom County sees. A short annual check catches small issues before they become expensive ones.
- Rinse siding periodically with a garden hose, especially north-facing or shaded walls where moss and algae take hold fastest
- Check caulking at trim, corners, and penetrations once a year and re-caulk any cracked or separated joints
- Trim back vegetation and tree limbs that keep siding shaded and damp longer than the rest of the house
- Look at fasteners and trim near ground level and at roof lines for early rust staining
- Clear debris from the base of walls and any drainage gaps so water isn't trapped against the siding
- Avoid pressure washing directly at seams and battens — a garden hose and soft brush are enough for fiber cement
None of this requires a contractor visit in most years — it's the kind of walk-around maintenance that keeps a correctly installed system performing the way it's supposed to for decades.
Why Hiring a Crew That Already Works in Cordata Matters
A siding crew that regularly works in the Cordata area already knows how local exposure, drainage patterns, and moss growth typically show up on homes here, and that experience shows up in the details — where extra flashing attention gets paid, which walls tend to hold moisture longest, and what batten spacing and trim choices actually weather well through repeated wet seasons. It also means a crew that's used to Whatcom County permitting and inspection expectations, so the project moves without surprises.
