Custer Board & Batten in Laurel: A Look That Has to Earn Its Keep
Board and batten has become one of the most requested siding styles in Whatcom County, and it's easy to see why. The strong vertical lines read as modern on a new build and as classic farmhouse on an older one, and it holds up visually in a way flat lap siding sometimes doesn't on a home with a lot of gables and mixed rooflines. But in Laurel, that style choice runs straight into a climate that doesn't forgive shortcuts. Salt-tinged air off the Sound, driving rain that comes in sideways during winter storms, and a moss season that seems to start earlier every year all put real stress on any siding system — and board and batten has more seams, more fastening points, and more places for water to find a way in than a standard lap profile. Done right, it's a durable, good-looking system. Done wrong, it's a maintenance headache within a few years.
What Laurel's Climate Actually Demands From Siding
Custer and the surrounding Laurel area sit close enough to the water that salt-laden air is a real factor, not a theoretical one. That air accelerates corrosion on exposed metal fasteners and flashing, which matters a lot on a siding style that relies on battens fastened down the length of every seam. Add in Whatcom County's long, wet winters — where rain doesn't just fall straight down but gets pushed sideways into wall assemblies during storms off the Strait — and you have conditions that punish any siding with a weak water-management plan. Then there's moss. Shaded, moist wall sections in this part of the county stay damp for weeks at a stretch, and moss and algae will colonize any surface that holds moisture or lacks a factory-cured finish. None of these are exotic problems for a Pacific Northwest coastal community, but they're exactly the conditions that separate a board and batten job that lasts twenty-plus years from one that needs recaulking and repainting in five.
The Three Things Working Against Your Siding Here
- Salt air: corrodes unprotected steel fasteners and lower-grade flashing over time, which is why fastener and flashing material choice isn't a minor detail on this coastline.
- Driving, wind-driven rain: pushes water into vertical seams and behind panels if there isn't a real drainage plane behind the siding.
- Extended moss and algae season: favors surfaces without a factory-applied, mold-resistant finish, especially on north-facing or tree-shaded walls that are common on wooded Laurel lots.
Why Board & Batten Specifically Is More Demanding to Get Right
A standard horizontal lap profile has one thing going for it structurally: gravity. Each course overlaps the one below it, so water is naturally shed downward and outward. Board and batten works differently. Vertical panels are joined with battens running top to bottom, which means every seam is a potential water path rather than a shingled overlap. That's not a flaw in the product — it's just the nature of the style — but it means the installation details matter more here than on almost any other siding profile. The panel-to-panel spacing, the fastening pattern into the battens, the flashing at every horizontal transition (window heads, belly bands, roof-to-wall intersections), and the ventilation behind the panels all have to be handled correctly, every time, or the style's clean vertical lines become a network of entry points for moisture.
What a Correct Board & Batten Installation Involves
The Drainage Plane Behind the Panels
The single most important part of any board and batten install in a climate like this one is what you don't see once the job is finished: the water-resistive barrier and drainage gap behind the siding. A proper rainscreen gap allows any moisture that does get past the panels to drain and dry out instead of sitting against the sheathing. Skipping this step, or using a cheaper flat-applied house wrap without a drainage layer, is one of the most common reasons board and batten siding fails early in wet coastal climates.
Fastening and Flashing
Every seam needs to be fastened into solid backing, not just into the panel face, and fastener heads need to be corrosion-resistant given the salt exposure in this area. Flashing at window heads, roof lines, and any horizontal trim break has to be integrated with the drainage plane, not just caulked over the top of it — caulk is a backup, not a waterproofing strategy on its own.
Panel Layout and Reveal
Batten spacing and reveal should be planned out before the first panel goes up, factoring in window and door locations so the pattern lands cleanly around openings instead of getting pieced together as the crew goes. This is a layout problem as much as an installation one, and it's where rushed jobs tend to show it.
What a Correct Job Should Include — Checklist
- A continuous water-resistive barrier with a true drainage gap behind the panels, not just house wrap
- Corrosion-resistant fasteners appropriate for a coastal, salt-air environment
- Integrated flashing at every window, door, roofline, and horizontal trim transition
- A planned batten layout that accounts for window and door openings before installation starts
- Factory-finished panels rather than field-primed material that will need repainting sooner
- Proper clearance between siding and grade, decks, and roof lines to avoid trapped moisture
Why We Install James Hardie for Board & Batten Here — and Nothing Else
We only install James Hardie fiber cement siding, and on a style as detail-sensitive as board and batten, that standard matters even more. Hardie's board and batten systems are non-combustible fiber cement, engineered specifically for wet, moderate coastal climates through their HZ5 product line — which is the right specification for Whatcom County. The ColorPlus finish is baked on at the factory rather than field-applied, which gives it better, more consistent resistance to the mold, mildew, and algae growth that Laurel's long moss season promotes, and it holds color longer than a job-site paint job exposed to salt air and UV. Hardie also backs its fiber cement with a strong, transferable limited warranty, which matters on a siding style where the difference between a correct and incorrect install shows up years down the road, not on day one. We've chosen not to install vinyl, LP SmartSide, primed wood, or other fiber cement alternatives for board and batten work in this climate — not because those products have no place anywhere, but because we don't think they hold up to Laurel's combination of salt air, driving rain, and moss exposure as well as Hardie does, and we'd rather stand behind one system we trust completely than offer several we have reservations about.
Our Process on Laurel Board & Batten Projects
We start with a walk-around assessment of the home, paying close attention to the sides most exposed to weather and any areas already showing moisture staining, moss buildup, or soft trim — those tell us a lot about how water has been moving around the house. From there we plan panel layout and batten spacing around your windows, doors, and rooflines before any material is ordered, so the finished look is intentional rather than improvised mid-install. Removal of old siding is done carefully, with the sheathing inspected and any water damage addressed before the new drainage plane goes on — covering up existing rot is not something we'll do. Flashing details get built out at every transition, panels go up on a planned layout with corrosion-resistant fastening, and the site is cleaned up as we go, not just at the end.
Cost Factors on a Board & Batten Project
Every home is different, but the price of a board and batten job in this area is driven by a handful of consistent factors. This table covers what typically moves the number up or down, without pretending to give you a specific quote sight unseen.
| Factor | Why It Affects Cost |
|---|---|
| Existing siding removal and disposal | Tear-off, hauling, and disposal add labor beyond the new install itself |
| Sheathing or moisture damage found underneath | Rot repair and sheathing replacement are addressed before new siding goes on, not skipped |
| Panel width and batten spacing chosen | Narrower reveals and more battens mean more fastening points and labor per square foot |
| Trim and corner detail complexity | Homes with more gables, dormers, or window trim require more custom flashing and cuts |
| Wall height and access | Two-story sections and steep or wooded lots common in Laurel can require more scaffolding or staging |
| Color selection | Factory ColorPlus finishes vary slightly in cost by color line compared to standard primed panels |
Living With Board & Batten Siding in a Salt-Air, Moss-Prone Climate
Even a correctly installed system benefits from a little routine attention here. An annual rinse-down removes early moss and algae growth before it takes hold, especially on shaded or north-facing walls. It's worth walking the exterior once a year to check caulking at trim joints and flashing for any early signs of wear, particularly after a hard winter storm season. Because Hardie's ColorPlus finish is factory-cured, it holds up to this routine far better than field-applied paint, which tends to chalk and fade faster under UV and salt exposure — meaning less repainting over the life of the siding, not none at all.
