Lynden Siding Board & Batten Siding Built for Deming's Corner of Whatcom County
Board and batten is one of the most requested siding profiles for homes around Deming, and it's easy to see why. The vertical lines suit farmhouse, craftsman, and modern rural builds alike, and it reads as a step up from flat lap siding without looking flashy. But board and batten is also a profile that punishes a sloppy installation faster than most. The wide flat boards and narrow battens create more seams, more fastener penetrations, and more places for water to find a way in than a standard lap job. In a climate like ours, where driving rain, damp air, and long stretches of shade combine to keep exterior surfaces wet for days at a time, those details are not optional extras — they are the difference between siding that lasts decades and siding that starts failing at the seams within a few winters.
We're a Lynden-based crew, and Deming is part of the territory we work regularly. That matters more than it sounds like it should. A profile like board and batten has to be adapted to the specific way weather moves through this part of Whatcom County, and a crew that's already put this siding on homes nearby isn't guessing at how it will hold up — they've seen it.
What Whatcom County Weather Does to Vertical Siding
Driving Rain and Wind-Driven Moisture
Storms in this region rarely fall straight down. Wind pushes rain sideways against exterior walls, and vertical siding profiles like board and batten are more exposed to that horizontal push than horizontal lap siding, which is engineered to shed water downward by design. Every batten seam is a spot where wind-driven rain can be forced upward or sideways behind the board if the installation doesn't account for it. This is why the water-resistive barrier and flashing details behind board and batten siding matter as much as the visible boards themselves.
Salt Air's Slow Corrosion
Whatcom County's marine-influenced air carries fine salt and moisture that settles on exterior surfaces year-round, not just on waterfront properties. Over time, that air accelerates corrosion on unprotected fasteners, trim, and metal flashing. Siding systems that rely on exposed steel fasteners or lower-grade trim hardware show that wear first — streaking, rust bleed, and loosening fasteners are common early failure points on homes that weren't detailed for this kind of exposure.
A Long Moss Season
Between shaded lots, tree cover, and a wet season that stretches across most of the year, moss and algae growth on north-facing and shaded walls is a fact of life here, not an occasional nuisance. Siding materials that absorb moisture give moss something to root into. Materials that shed water cleanly and dry out between storms stay cleaner longer and hold paint and caulking better over the years.
Board & Batten vs. Other Siding Profiles for This Climate
Board and batten isn't wrong for this area — it's a strong choice when it's built correctly. But it behaves differently than other profiles, and homeowners weighing their options should understand the trade-offs before deciding.
| Factor | Board & Batten | Lap Siding | Panel Siding |
|---|---|---|---|
| Water shedding | Good, if flashed and battened correctly | Excellent by design | Depends heavily on seam sealing |
| Seams exposed to wind-driven rain | More seams, more detail work required | Fewer vertical seams | Large seams, fewer but higher-stakes |
| Visual style fit for rural/farmhouse homes | Very strong match | Traditional, versatile | Modern, minimal |
| Moss resistance in shaded lots | Good with a non-absorptive material | Good with a non-absorptive material | Good with a non-absorptive material |
| Installation sensitivity | High — batten spacing and fastening must be precise | Moderate | Moderate to high |
The common thread across every profile is that the siding material matters as much as the shape. A material that swells, absorbs water, or needs frequent recoating will struggle in any profile once it's exposed to this climate long enough. The profile decides the look; the material decides how long that look holds up.
What a Correct Board & Batten Installation Involves
Substrate and Weather-Resistive Barrier
Before a single board goes up, the wall needs a continuous weather-resistive barrier, properly lapped and sealed at every seam, window, and door opening. On board and batten jobs especially, this layer is the real first line of defense — the siding itself is the second. Any gaps, tears, or shortcuts here get covered up and become invisible problems for years.
Batten Spacing and Fastening
Batten spacing has to account for panel expansion and contraction, fastener placement has to hit framing consistently, and fasteners themselves need to be corrosion-resistant given the salt content in the air here. Battens fastened too tight to the panel below, or spaced without allowing for movement, tend to crack or pop loose over a few seasons.
Flashing at Windows, Doors, and Penetrations
Every window, door, hose bib, and vent penetration is a place where water wants to get behind the siding. Correct flashing — installed in the right order, lapped so water always moves outward and downward — is what actually keeps a wall dry, not the caulking on top of it. Caulk is maintenance; flashing is the structure.
Why We Install Only James Hardie Board & Batten Systems
We install James Hardie exclusively — HardiePanel vertical siding with HardieTrim battens — and we don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. That's a deliberate standard, not a marketing line, and it's worth explaining honestly.
Wood and engineered-wood board and batten products can look excellent when new, and some homeowners genuinely prefer the texture. But they depend on an intact factory coating or field-applied paint to keep moisture out, and in a climate with this much sustained dampness, any breach in that coating — a nail pop, a hairline crack at a batten seam, a scuff during a ladder job — becomes an entry point for moisture that wood-based cores don't handle well over time. Vinyl board and batten sidesteps the rot question but introduces its own trade-off: it flexes with temperature swings, its color is molded in rather than factory-baked, and it's more vulnerable to impact cracking, none of which suits a climate with this much wind exposure.
James Hardie fiber cement is non-combustible, doesn't swell or rot from moisture absorption the way wood-based products can, and comes with a factory-applied ColorPlus finish that's baked on rather than field-painted, which means better color retention and fewer repaint cycles over the life of the siding. Hardie's HZ5 product line is engineered specifically for climates with sustained damp and freeze-thaw exposure, which describes this part of Washington well. It also carries a strong transferable warranty, which matters if the home changes hands. None of that means Hardie is maintenance-free — it still needs to be caulked, inspected, and occasionally repainted at trim and cut edges — but it starts from a materially stronger position for a wall that's going to spend a lot of its life wet.
Our Process for Deming Board & Batten Projects
The steps don't change much from house to house, but the details we check are specific to this area's exposure:
- On-site assessment of existing siding, sheathing condition, and any moisture damage already present, with particular attention to shaded and north-facing walls.
- Removal of old siding and inspection of the sheathing underneath — any soft or water-damaged sheathing gets addressed before anything new goes up.
- Installation of a continuous weather-resistive barrier with properly lapped seams and sealed penetrations.
- Installation of HardiePanel and HardieTrim battens per manufacturer fastening and spacing specifications, using corrosion-resistant fasteners.
- Flashing of all windows, doors, and penetrations before trim and battens close them in.
- Caulking, touch-up, and a final walk-through with the homeowner before cleanup.
Maintenance Checklist for Board & Batten Homes in This Climate
A correctly installed board and batten system is low-maintenance, not no-maintenance. In this climate, a short annual check goes a long way:
- Inspect caulking at batten seams, window and door trim, and corner boards once a year for cracking or separation.
- Check shaded and north-facing walls for early moss or algae growth and clean gently before it spreads.
- Look at gutters and downspouts near siding for overflow that could be soaking a wall repeatedly.
- Watch for streaking near fasteners or trim, which can signal a corroding fastener underneath.
- Keep vegetation and mulch beds pulled back from direct contact with the bottom of the siding.
Cost Factors for Board & Batten Siding in Deming
Every property is different, and we won't quote a number without seeing the house, but these are the factors that most often move the price up or down on a board and batten project in this area:
| Factor | Why It Matters |
|---|---|
| Existing siding removal | Multiple layers or damaged material underneath add labor and disposal time |
| Sheathing repair | Water-damaged sheathing found during tear-off has to be replaced before new siding goes on |
| Trim and batten complexity | More windows, corners, and architectural detail mean more precision cuts and flashing |
| Wall height and access | Two-story walls, steep grades, and limited access affect staging and labor time |
| Color and finish selection | Factory ColorPlus finishes vary slightly by line and color depth |
Why Hiring a Crew That Already Works Deming Matters
Board and batten siding is unforgiving of guesswork, and a crew that's already worked properties in and around Deming isn't learning the local weather patterns on your home. We know how wind-driven rain behaves against exterior walls out here, how long shaded sides of a house stay damp after a storm, and what it takes to keep fasteners and flashing ahead of the salt content in the air. That local track record shows up in the details — batten spacing, flashing sequence, fastener choice — that you can't see once the job is finished but that determine whether it holds up for the next twenty years.
