Lynden Siding Why Board & Batten Suits Deming Homes
Board and batten siding has a clean, vertical look that fits the farmhouse, craftsman, and rural properties common around Deming and the surrounding Nooksack River valley. The wide flat boards and narrow battens covering each seam give a home a distinct, textured profile that's different from standard horizontal lap siding — and it holds up well on the barns, shops, and larger accent walls that are common on the acreage properties out this way. It's a popular choice for homeowners who want their siding to look intentional, not just functional.
But board and batten is also a style that punishes a poor installation faster than lap siding does. The vertical orientation, the number of seams, and the reliance on battens to shed water all mean the details matter more here than on almost any other siding profile. In a climate like ours, getting those details right is the difference between siding that looks good for decades and siding that starts showing problems in five or six years.
What Deming's Climate Does to Siding Over Time
Whatcom County sits in a marine-influenced climate, and even inland communities like Deming feel it — long stretches of driving rain, heavy overcast skies, and the kind of persistent dampness that keeps shaded exterior walls wet far longer than homeowners expect. Add in the salt-laden air that moves through the broader Puget Sound region and settles on exterior materials over time, and you've got conditions that are genuinely hard on siding.
The moss season here is long, too. Homes tucked near trees, in the shade of the foothills, or on north-facing walls can stay damp enough to grow moss and algae for much of the year. Moss doesn't just look bad — it holds moisture against the siding surface and, on materials that aren't built for it, that trapped moisture is what starts rot, delamination, or paint failure.
Why This Matters More for Board & Batten Specifically
Vertical siding has more places for water to find a way in. Every batten strip covers a seam, and every seam is a potential path for moisture if it isn't flashed and fastened correctly. Horizontal lap siding sheds water downward by design; board and batten relies on the installer getting the layering, gaps, and fastening pattern right so water runs down and off rather than working its way behind the boards.
Why Material Choice Matters More With Vertical Siding
We get asked fairly often why we don't install board and batten in vinyl, LP SmartSide, primed spruce, or cedar. The honest answer is that vertical profiles expose the weaknesses of those materials faster than horizontal siding does.
- Wood-based panels (LP SmartSide, primed spruce): engineered or solid wood products can perform well for years, but they depend heavily on caulking, paint maintenance, and cut-edge sealing. On a vertical profile with more seams and battens, any missed maintenance point becomes a moisture entry point sooner.
- Vinyl board and batten: vinyl expands and contracts with temperature swings, and in a wet climate that movement can open small gaps at the battens over time. It's also more prone to visible fading and cracking in cold snaps than a lot of homeowners expect.
- Cedar: beautiful when new, but it requires ongoing staining or sealing to hold up against constant moisture and moss growth — a maintenance commitment that's genuinely demanding in a climate this wet.
None of these are "bad" products in every situation. They're just products whose trade-offs get amplified by a vertical siding profile in a high-moisture climate, which is why we standardized on James Hardie fiber cement for board and batten work.
James Hardie Board & Batten: How It's Built
James Hardie's vertical siding system uses fiber cement panels — a mix of cement, sand, and cellulose fiber — engineered to resist moisture absorption, swelling, and the kind of rot that eventually catches up with wood-based products. It's non-combustible, which is a real advantage for the properties around Deming that back up to wooded lots.
The panels come with a factory-applied ColorPlus finish, which is baked on under controlled conditions rather than brushed on at the jobsite. That matters in a climate like ours because a factory finish resists peeling and fading from constant moisture exposure far better than a field-applied paint job, and it comes backed by its own finish warranty separate from the product warranty.
HZ5 Engineering for Our Climate
Hardie engineers its products in different formulations for different climate zones. The HZ5 product line is built for regions with more moisture and freeze-thaw cycling — which fits Whatcom County's wet winters and damp shoulder seasons well. It's one of the reasons we don't treat "siding" as a one-size-fits-all product; the version installed should match what the local climate actually does to a house.
What a Correct Board & Batten Installation Involves
Drainage Plane and Rain Screen Gap
Board and batten should never be installed directly against the weather-resistive barrier with no gap. A proper installation includes a drainage plane — furring strips or a rain screen product — that creates space behind the panel for any moisture that does get in to drain and dry out instead of sitting against the sheathing.
Fastening and Batten Placement
Fasteners need to land in the panel field correctly and be spaced to manufacturer spec, and battens need to be positioned to actually cover the seam beneath them with enough overlap to shed water in driving rain — the kind of weather Deming sees plenty of in the fall and winter.
Flashing at Every Transition
Windows, doors, roof lines, and the bottom termination of the siding are where most real-world failures start. Each of these transitions needs proper flashing and clearance — siding that starts too close to grade, a deck, or a roofline holds moisture and invites the rot and moss growth that's so common in this area.
Comparing Board & Batten Material Options
| Material | Moisture Resistance in Wet Climates | Maintenance | Typical Lifespan |
|---|---|---|---|
| James Hardie Fiber Cement | High — engineered for moisture, non-combustible | Occasional wash; factory finish reduces repainting | Multiple decades when installed to spec |
| Vinyl | Moderate — can gap or warp with temperature swings | Low, but limited repair options if damaged | Variable, shorter in harsh weather |
| LP SmartSide / Engineered Wood | Moderate — depends heavily on sealed edges and maintenance | Regular caulk and paint upkeep required | Shorter without diligent maintenance |
| Cedar / Primed Spruce | Lower without active upkeep — natural wood absorbs moisture | High — regular staining or sealing needed | Shorter in constant moisture exposure |
This table reflects general product behavior, not a claim that every installation of every product fails — installation quality and homeowner maintenance affect all of these materials. It's simply why, given the choice, we install fiber cement on the vertical profiles going up on homes near Deming.
Our Process for Deming Board & Batten Projects
- On-site assessment: we look at drainage, shade patterns, existing moss or moisture issues, and how the home is currently venting and shedding water.
- Removal and inspection: once old siding comes off, we check the sheathing underneath for hidden rot or moisture damage before anything new goes up.
- Drainage plane installation: furring or rain screen material goes on first, giving the new siding a gap to breathe and drain.
- Panel and batten installation: Hardie panels and battens go up to manufacturer spec, with attention to fastening pattern and batten overlap.
- Flashing and trim detail: windows, doors, and roof transitions get sealed and flashed correctly before final trim goes on.
- Final walkthrough: we go over the finished work with the homeowner and flag anything worth watching for in the first year.
Maintaining Board & Batten Siding in a Wet Climate
- Rinse siding annually to remove pollen, dirt, and early moss growth before it takes hold
- Trim back tree branches and shrubs that keep siding shaded and damp longer than necessary
- Check caulking around windows and trim each year, especially heading into the wet season
- Watch for moss buildup at the base of battens and in shaded corners — address it early rather than letting it sit
- Keep gutters clear so overflow doesn't run down the siding face repeatedly
Why Hiring a Crew That Already Works Deming Matters
Board and batten installation isn't complicated in theory, but getting the drainage plane, flashing, and batten spacing right in a climate that stays wet for months at a time takes attention that generic installation experience doesn't always cover. A crew that regularly works in Whatcom County has already seen how moss, shade, and driving rain behave on homes out toward Deming and the foothills, and builds the installation around that reality instead of a generic spec sheet.
That local familiarity also shows up in smaller decisions — where to add extra flashing, which walls need a wider rain screen gap because of shade exposure, and how to sequence a project around our wetter months so the substrate isn't exposed longer than it needs to be.
