Board & Batten Siding Built for Edgemoor's Wooded Bluffs
Edgemoor sits in a setting that's a little different from most of Bellingham — mature evergreen canopy, larger wooded lots, and homes perched on bluffs above Bellingham Bay and Chuckanut Bay. Board and batten fits that setting well. The vertical lines read as clean and contemporary against a craftsman or modern custom home, and the profile has become a common choice for homeowners here who want a siding style that matches the neighborhood's architecture rather than a look borrowed from a subdivision. What board and batten is not, though, is a low-detail siding job. Every seam between a board and its batten is a place water can try to work its way behind the wall, and in a neighborhood with this much tree cover, bay exposure, and bluff-top wind, how those seams are built matters as much as which brand ends up on the invoice.
We install James Hardie fiber cement board and batten exclusively, and we detail every seam, fastening pattern, and flashing point around what Edgemoor's specific combination of shade, salt air, and driving rain does to a wall over decades, not around what looks good on the day the crew packs up.

What Edgemoor's Setting Asks of a Board & Batten Wall
Canopy Shade and an Extended Moss Season
The mature tree cover that makes Edgemoor's lots so desirable also means a lot of walls here spend much of the year in partial or full shade. Shaded siding dries slower after rain, and slower drying means a longer active season for moss and mildew on any wall that faces away from direct sun. Board and batten has more seam length per square foot than a standard lap profile, and each of those seams is a place where a batten installed tight against its board — instead of with the clearance the material needs — traps moisture right where it can't evaporate.
Salt Air Off the Bay
Homes closer to the water on Edgemoor's bluffs get steady exposure to salt-tinged air coming off Bellingham Bay. That's hard on any exposed metal, and board and batten uses more fasteners per square foot than most other siding profiles because both the boards and the battens each need to be secured. Getting the fastener spec right — corrosion-resistant, correctly sized, correctly spaced — carries more weight on this profile than on a simpler one.
Wind and Rain Funneled by the Bluff
Even with tree cover breaking up direct wind, homes on Edgemoor's bluffs still take wind-driven rain differently than a sheltered inland lot — elevation and proximity to open water tend to push moisture sideways against upper walls and gable ends. A vertical profile like board and batten gives that wind-driven rain a lot of joint length to test, which is exactly why the lap and clearance details at every batten need to be right, not approximate.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, simply because it has more seams and more exposed edge than most profiles. That's a big part of why we don't offer LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. These are legitimate products, and other contractors install them competently — but on a profile with this many joints, on lots this shaded and this close to the water, we standardized on one system we trust completely rather than offering several with different long-term risk profiles.
| Material | Behavior at Batten Seams | Maintenance Under Canopy Shade | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Low; factory finish resists moss and fading | 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, climate-dependent |
| Vinyl | Can warp or gap at battens with temperature swings; seams less rigid | Low, but hidden moisture behind panels is hard to catch | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without consistent sealing | High; shaded walls need more frequent resealing or repainting | 15-25 years with consistent upkeep |
James Hardie's fiber cement core doesn't expand and contract with moisture the way wood-based products do, which matters most on a profile built entirely from vertical joints. The factory-applied ColorPlus finish also means the cut edges we prime on site are the exception rather than the rule — unlike field-painted materials, where every board face on a shaded, slow-drying wall depends on paint holding up against conditions it wasn't built to handle indefinitely.
What a Correct Board & Batten Install Actually Involves
The finished look of board and batten is simple — vertical boards, battens over the seams — but a correct install involves more behind that surface than most siding profiles:
- House wrap or weather-resistive barrier installed and properly lapped 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 shaded wall
- Boards fastened with corrosion-resistant fasteners at the manufacturer's specified spacing, not just enough to hold the piece up
- Battens set with the clearance Hardie's install spec requires, not caulked tight, so the wall can shed water rather than trap it
- Properly flashed and lapped transitions at windows, doors, corners, and the base of the wall, where the vertical run meets a horizontal surface
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before installation
Skip any of these and the wall can still look right for a season or two. The problems that follow — seam staining, soft spots near the base, paint failure along battens on the shadiest elevations — take a few wet winters to show up, which is exactly why a corner-cutting install can look fine at handoff and still fail the homeowner years later.
Our Process for an Edgemoor Board & Batten Project
Walkthrough and Assessment
We start by looking at each wall on its own terms — which face the bay directly, which sit under heavy canopy and stay damp longest, and whether the existing wall assembly already has moisture issues that need addressing before new siding goes on. Installing board and batten over a wall with hidden rot or poor drainage just buries the same problem under new material.
Detailing the Plan Before Install Day
On larger, more architecturally detailed Edgemoor homes, we work out batten spacing, corner details, and how the siding meets windows, trim, and rooflines before crews start cutting material. With this many seams, planning the details on paper first avoids field improvisation — which is usually where corners get cut on a job like this.
Installation to Manufacturer Spec
Every fastener, gap, and flashing lap follows James Hardie's published installation requirements for this climate zone. That's part of what keeps the manufacturer's warranty intact, and part of why the wall performs the way it's supposed to for decades rather than 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 to look for if you ever want to check the wall yourself — especially on the shadiest elevations of the property.
Why Hire a Crew That Already Works Edgemoor
Board and batten rewards experience with this specific setting in a way many siding profiles don't, because the failure points are subtle and slow to surface. A crew that's installed this profile across Edgemoor's wooded, bluff-top lots has already seen which elevations need extra drainage attention because of canopy shade, how much batten clearance actually holds up against bay-driven wind and salt air, and where a rainscreen gap is worth the added cost versus where it's optional. That judgment doesn't show up on a spec sheet, and it's the difference between a wall that still looks and performs the same in fifteen years and one that's showing seam staining under the trees within five.
Cost Factors for Board & Batten in Edgemoor
Board and batten typically costs more per square foot than standard lap siding, mainly due to the added material — battens on top of boards — and the extra labor of fastening and detailing two layers instead of one. On Edgemoor properties specifically, a few things tend to move the price:
| Factor | Why It Matters |
|---|---|
| Wall height and architectural detail | Custom homes with more corners, dormers, and window trim mean more cuts and flashing details |
| Existing wall condition | Shaded walls found to have hidden moisture damage during tear-off need repair before new siding goes up |
| Lot access and tree cover | Wooded, bluff-top lots can limit staging space and add labor time for material handling |
| Batten spacing and reveal | Tighter spacing uses more material and more fastening labor |
| Site slope and drainage work | Bluff and slope lots sometimes need added drainage detailing at the base of the wall |
We'll walk your specific property and give you real numbers rather than a rough per-square-foot estimate — two Edgemoor homes with similar square footage can land at very different costs depending on how many of these factors are actually 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. On a shaded, bay-exposed lot where a poor install can take a couple of wet winters to reveal itself, that's exactly why we treat the planning and detailing phase as seriously as the install itself — getting it right the first time costs a lot less than tearing out a wall that was done wrong.
