Bellingham Why Board & Batten Is Making a Comeback in Whatcom County
Board and batten has old New England barn roots, but it's become one of the most requested looks on new builds and remodels around Bellingham. The vertical lines read as modern-farmhouse or craftsman depending on the trim details, and it pairs well with the mix of architecture you see from the Lettered Streets to Fairhaven to the newer developments out toward Ferndale and Lynden. The look is simple. Getting it to actually perform for 30-plus years in this climate is the harder part, and that's where a lot of board and batten siding goes wrong.
What Board & Batten Actually Is
It's not a special material — it's a pattern. Wide vertical panels (or individual boards) are installed first, then narrower strips called battens are fastened over the seams between them. Traditionally this was done with solid wood, and later with panels of engineered wood or vinyl. We install it exclusively in James Hardie fiber cement, using Hardie's vertical panel and batten trim products designed specifically for this application.
The distinction matters because board and batten has more seams and more fastener penetrations per square foot than lap siding. Every one of those seams and fastener points is a place water can get behind the cladding if the assembly isn't detailed correctly. In a climate like ours — salt air off Bellingham Bay, driving rain that comes in sideways off the Sound, and a moss season that stretches from fall through spring — an assembly that's marginal on the East Coast or in a dry climate can fail here in a fraction of the time.
Where Board & Batten Installations Go Wrong
Most of the board and batten problems we get called out to inspect trace back to a handful of the same mistakes:
- No rainscreen gap. Battens and panels fastened flat against the weather-resistive barrier trap moisture against the wall assembly instead of letting it drain and dry. James Hardie's own installation instructions call for a drainable gap in most assemblies, and it's not optional in a climate this wet.
- Battens over-fastened or fastened in the wrong location. Battens need to be nailed to hit framing or blocking, not just through the panel into open air, and fastener spacing that's too tight or placed at panel edges can crack the batten or the panel underneath it over time as the material moves with temperature and moisture.
- No flashing at seams and penetrations. Every panel joint, window, and light fixture penetration needs proper flashing and sealant detailing. Skipping this because "the batten covers it" is a common shortcut that shows up as staining and rot behind the wall five to ten years later.
- Wrong caulk or no expansion gap. Fiber cement needs to be installed with the gaps and sealants specified by the manufacturer. Butting boards tight or using the wrong sealant leads to cracking and bulging.
None of this is unique to board and batten — it's the same physics that governs any siding install — but the pattern has less forgiveness for shortcuts because there are simply more seams and fasteners in play.
Why We Use James Hardie for This Application
We install James Hardie exclusively, and board and batten is one of the clearest cases for why. Hardie's fiber cement is dimensionally stable — it doesn't swell, shrink, or cup the way wood-based panel products can when they take on moisture, which matters a great deal when you're fastening a batten directly over a seam and expecting that joint to stay tight for decades. It's also non-combustible, which matters more each year as wildfire smoke seasons creep further into Western Washington summers.
For board and batten specifically, we work with Hardie's HZ10 product line, engineered for the wetter, milder climate zones that include the Pacific Northwest. The factory-applied ColorPlus finish is baked on under controlled conditions rather than field-painted, which matters on a pattern with this many exposed edges and joints — factory finish holds color and resists moisture intrusion at cut edges better than a job-site paint job, especially with the salt air Bellingham gets off the water.
What Correct Installation Looks Like
| Step | What It Involves |
|---|---|
| Water-resistive barrier | Continuous, correctly lapped, integrated with window and door flashing before any siding goes up |
| Rainscreen gap | Furring or a drainable house wrap system to create a drainage and drying plane behind the cladding |
| Panel fastening | Correct fastener type, spacing, and embedment into structural framing per Hardie's published specs |
| Batten installation | Fastened through to framing, centered over seams, with the correct reveal and expansion gap |
| Flashing and sealant | Manufacturer-approved sealant at joints and penetrations, factory-finish touch-up paint at cut ends |
Skip any one of these steps and the siding may look fine for a year or two. In Whatcom County's wet season, the underlying problems tend to show up as staining, soft spots, or moss and algae holding moisture against the wall well before the siding itself is anywhere near the end of its service life.
What This Means for Your Project
If you're planning a board and batten look for a remodel or new build in Bellingham, Whatcom County, or the surrounding area, the design decision is the easy part. The installation detailing — rainscreen, fastening, flashing, and using a product engineered for this climate — is what determines whether it still looks and performs the way you want it to in year twenty. We'd rather walk you through those details up front than have you find out the hard way.
