Bellingham Siding Board & Batten Siding for Columbia Homes
Columbia is one of Bellingham's older in-town neighborhoods, and that shows up in the housing stock: a mix of early-to-mid-20th-century cottages and bungalows, additions and remodels layered on over the decades, and newer infill sitting right next to homes that have been through generations of Bellingham weather. Board and batten fits naturally into that mix — it reads as period-appropriate on an older cottage and clean and current on newer construction, which is part of why we get asked about it so often in this part of town. What doesn't change from house to house is what the profile demands structurally. Board and batten is a vertical siding pattern with a narrow strip covering every seam between boards, and each of those seams is a place water can try to work its way behind the wall. In a neighborhood this close to the water, with the shade and moisture that come with mature trees and narrow, tree-lined streets, how those seams are built matters as much as which siding brand goes on the invoice.
We install James Hardie fiber cement board and batten exclusively, and every seam, fastening pattern, and flashing detail on a Columbia project gets built around what this specific corner of Bellingham does to a wall over ten, twenty, and thirty years.
What This Neighborhood Asks of a Board & Batten Wall
Wind-Driven Rain Close to the Water
Columbia sits close enough to the bay and Whatcom Creek that wind-driven rain is a regular fact of life, not an occasional storm event. Rain that comes in sideways puts real pressure on vertical seams, and a batten that's caulked tight instead of properly lapped and back-clearanced turns into a wick that draws water toward the fastener line instead of shedding it away from the wall.
Moss and Shade From Mature Trees
Many of Columbia's older lots carry mature trees and tight setbacks between homes, which means plenty of walls here spend most of the year in partial shade. Shaded, slow-to-dry siding is exactly where moss and mildew take hold, and on a board and batten wall that moisture gets trapped right at the seam if the batten is nailed down flush with no room for the wall to breathe and dry.
Older Wall Assemblies Underneath
Because so many Columbia homes have been re-sided or added onto over the years, what's actually behind the existing siding varies a lot more here than on a newer subdivision built to one spec. Some walls have modern house wrap and adequate drainage; others were sided decades ago under a different standard entirely. A board and batten install that doesn't account for what's already there is just covering up whatever problems, or lack of problems, already exist in the wall.
Why Product Choice Matters More on This Profile
Board and batten multiplies whatever weaknesses a siding material already has, simply because there's more seam length and more exposed edge per square foot than on a standard lap profile. That's a big 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, in a climate this consistently wet, we standardized on one material system we're willing to stand behind completely.
| Material | Behavior at Batten Seams | Maintenance in This Climate | 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 upkeep | 15-25 years, climate-dependent |
| Vinyl | Can warp or gap at battens in temperature swings; seams less rigid | Low, but hidden moisture problems are hard to spot | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | High; repainting or resealing on a recurring cycle | 15-25 years with consistent upkeep |
Fiber cement's core doesn't expand and contract with moisture the way wood-based products do, and that's exactly the property that matters most on a profile built entirely from vertical seams. 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 quality holding up outdoors year after year.
What a Correct Board & Batten Install Actually Involves
The finished look is simple — vertical boards, battens over the seams — but there's more going on behind that surface than most other siding profiles require:
- 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 the wall
- Boards fastened with corrosion-resistant fasteners at the manufacturer's specified spacing, not just enough to hold the board in place
- Battens set with the clearance Hardie's install spec calls for, not caulked tight, so the wall can shed water instead of trapping it
- Properly flashed 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 one of these and the wall can still look right for a season or two. The problems that follow — staining at the seams, soft spots near the base, paint failure along battens — take a few wet winters to surface, which is exactly why a corner-cutting install can get away with it right up until the homeowner is the one dealing with the repair.
Our Process for a Columbia Board & Batten Project
Walkthrough and Assessment
We start by looking at the specific walls involved: which ones take weather directly, which sit in shade from trees or a neighboring structure, and what condition the existing wall assembly is in on a home that may have been re-sided before. Board and batten over a wall with hidden rot or inadequate drainage just buries the same problem under new material.
Detailing the Plan Before Install Day
Batten spacing, corner details, and how the siding meets windows, trim, and rooflines get worked out before crews start cutting material. On a profile with this many seams, and on lots where houses sit close together, planning the details on paper first avoids field improvisation — which is usually where corners end up getting 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 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 down the road.
Why Hire a Crew That Already Works This Neighborhood
Board and batten rewards familiarity with a specific area in a way a lot of siding profiles don't, because the failure points are subtle and slow to show up. A crew that's already worked on Columbia's older housing stock has a feel for which walls need extra attention because of shade and tree cover, how much batten clearance actually holds up in a climate this damp versus what a generic install guide assumes, and what to expect when opening up a wall on a home that's been added onto or re-sided over the years. That judgment doesn't show up on a spec sheet — it's the difference between a wall that still looks and performs the same in fifteen years and one that's showing seam staining by year five.
Cost Factors for Board & Batten in Columbia
Board and batten typically runs more per square foot than standard lap siding, mainly because of the added material (battens over boards) and the extra labor of fastening and detailing two layers instead of one. Beyond the base material, a few things move the price on a given home in this neighborhood:
| Factor | Why It Matters |
|---|---|
| Age and condition of existing siding | Older walls found to have rot or moisture damage during tear-off need repair before new siding goes up |
| 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 |
| Site access | Narrow lots and tight spacing between neighboring homes can add staging and labor time |
We'll walk your specific home and give you real numbers rather than a rough estimate off square footage alone — two similarly sized houses in this neighborhood can have very different board and batten costs depending on how many of these factors are in play.
Getting It Right the First Time
Board and batten isn't 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 why we treat the planning and detailing phase 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, especially on an older home where the underlying wall condition is already an unknown until it's opened up.
