Bellingham Board & Batten Siding for Sunnyland Homes
Sunnyland is one of Bellingham's older, more established residential neighborhoods, and that shows up in its housing stock — a mix of mid-century homes and newer infill sitting under a lot of mature tree canopy. That tree cover is part of what makes the neighborhood feel the way it does, but it also means a lot of Sunnyland's exterior walls spend more of the year shaded and damp than homes out in the open. Board and batten has become a popular upgrade here, both on remodels of older homes and on new builds going up on smaller lots, because the vertical lines read as clean and current against the neighborhood's mostly modest, close-set houses. What doesn't change with the style, though, is the physics of the wall behind it: board and batten has more vertical seams than standard lap siding, and every one of those seams is a place moisture can try to work its way in.
We install James Hardie fiber cement board and batten exclusively, and on a shaded, moss-prone lot like a lot of what you'll find in Sunnyland, we build the fastening, clearance, and drainage details around what this specific setting does to a wall over ten, twenty, and thirty years — not around what looks fine on install day.
What Sunnyland's Setting Asks of a Board & Batten Wall
Shade and Slow-Drying Walls
A lot of Sunnyland's lots have mature trees close to the house, and north- or side-facing walls under that canopy can stay damp for days after a storm passes. On a lap-siding wall that's a nuisance. On a board and batten wall, where the batten strip sits directly over the seam between two boards, a slow-drying wall means the joint itself stays wet longer — which is exactly the condition moss and mildew need to take hold at the fastener line.
Driving Rain Off the Bay
Sunnyland sits a bit inland from Bellingham Bay, but it's still well within reach of the wind-driven rain that comes off the Salish Sea through the fall and winter. Vertical siding profiles give that sideways rain a lot of joint length to work against, and a batten that's caulked tight instead of properly lapped with room to breathe ends up pulling water toward the fasteners instead of shedding it.
Older Homes, Newer Siding
Because a good share of Sunnyland's housing stock predates modern siding codes, board and batten installs here are often a re-side over a wall assembly that's decades old. That means the condition of the sheathing and weather barrier underneath matters as much as the new siding going on top of it — a wall with hidden rot or an inadequate drainage plane will cause the same problems again under new material if it isn't addressed first.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, simply because there are more seams and more exposed edge per square foot than on a standard lap wall. That's part of why we don't offer LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. Those are legitimate products, and other contractors install them competently — but on a profile with this many joints, going up on shaded, slow-drying lots like a lot of Sunnyland's, we standardized on one material system we trust completely.
| Material | Behavior at Batten Seams | Maintenance Under Shade/Tree Cover | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss and staining | 30+ years with proper install |
| LP SmartSide (engineered wood) | More sensitive to moisture at cut edges and fastener holes | Moderate; edge sealing needs regular upkeep in shade | 15-25 years, condition-dependent |
| Vinyl | Can warp or gap at battens with temperature swings; seams less rigid | Low, but trapped moisture behind panels is hard to spot | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High; recurring cleaning and resealing under tree cover | 15-25 years with consistent upkeep |
Fiber cement's core doesn't expand and contract with moisture the way wood-based products do, which matters most on a profile built entirely out of vertical seams sitting under shade for much of the year. James Hardie's factory-applied ColorPlus finish also means the cut edges we prime on site are the exception, not the rule — unlike a field-painted material, where every board face depends on paint holding up outdoors, moss and all.
What a Correct Board & Batten Install Actually Involves
The finished look is simple — vertical boards, battens over the seams — but a correct install on a shaded Sunnyland lot has more going on behind the surface than most other siding profiles:
- House wrap or weather-resistive barrier installed and lapped correctly before any siding goes up
- A drainage gap or rainscreen behind the siding so moisture that gets past the surface can dry out instead of sitting against a wall that's already slow to dry from shade
- Boards fastened with corrosion-resistant fasteners at the manufacturer's specified spacing, not just enough to hold the material up
- Battens set with the clearance James Hardie's install spec calls for, not caulked tight, so the wall can shed water instead of trapping it at the seam
- Properly flashed and lapped transitions at windows, doors, corners, and the base of the wall
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before installation
Skip any one of these and the wall can still look right for a year or two. The problems that show up when they're skipped — staining at seams, moss creeping in along battens, soft spots at the base of shaded walls — take a few wet seasons to appear, which is exactly why they're easy for a rushed install to get away with until the homeowner is the one dealing with it.
Our Process for a Sunnyland Board & Batten Project
Walkthrough and Assessment
We start by looking at your specific walls — which ones sit under the heaviest tree cover, which face the prevailing weather, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes up. On an older Sunnyland home, that assessment often turns up things worth fixing before the new siding hides them.
Detailing the Plan Before Install Day
We plan batten spacing, corner details, and how the siding will meet windows, trim, and rooflines before crews start cutting material. On a profile with this many seams, working the details out on paper first avoids field improvisation, which is usually where corners get cut.
Installation to Manufacturer Spec
Every fastener, gap, and flashing lap follows James Hardie's published installation requirements for this climate zone, not a generic national standard. That's what keeps the manufacturer's warranty intact and what keeps the wall performing the way it's supposed to for decades, not years.
Final Walkthrough
We walk the finished job with you, cover what little maintenance board and batten actually needs, and make sure you know what a healthy wall looks like if you ever want to check it yourself.
Why Hire a Crew That Already Works Sunnyland
Board and batten rewards experience with a specific setting in a way a lot of siding profiles don't, because the failure points here are subtle and slow to show up. A crew that's installed this profile on tree-shaded, close-set Sunnyland lots through multiple wet seasons has already seen which walls need extra drainage attention because of tree cover, how much batten clearance actually holds up in a spot this shaded versus what a generic install guide assumes, and where an older home's wall assembly is likely to need attention before new siding goes on. That judgment doesn't show up on a spec sheet, and it's the difference between a board and batten wall that still looks and performs the same in fifteen years and one that's showing moss and seam staining by year five.
Cost Factors for Board & Batten in This Area
Board and batten typically costs more per square foot than standard lap siding, mainly because of the added material — battens on top of boards — and the extra labor of fastening and detailing two layers instead of one. Beyond that base cost, a few things tend to move the price on a given Sunnyland home:
| Factor | Why It Matters |
|---|---|
| Existing wall condition | Older homes sometimes need sheathing or moisture repair found during tear-off before new siding goes up |
| Tree cover and access | Close-set lots and mature landscaping can add setup and cleanup time |
| Wall height and complexity | More corners, dormers, and transitions mean more cuts and flashing details |
| Batten spacing and reveal | Tighter spacing uses more material and more fastening labor |
| Trim and window detailing | More openings mean more flashing and finish work around each one |
We'll walk your specific home and give you real numbers rather than a rough estimate off square footage alone — two Sunnyland homes with similar footprints can land at very different costs depending on how many of these factors are in play.
Getting It Right the First Time
Board and batten is not a forgiving profile to redo. Because the battens cover the seams between boards, correcting a bad install usually means pulling battens, boards, or both, rather than a simple patch. That's part of why we treat the planning and detailing phase of these projects as seriously as the install itself — the cost of getting it right the first time is a lot lower than the cost of tearing out a wall that was installed wrong under a shaded canopy that never gave it a chance to dry.
