Bellingham Board & Batten in Columbia: Style Meets Substance
Board and batten has deep roots in Pacific Northwest home design, and it shows up all over Columbia — on craftsman bungalows, older cottages, and the newer infill homes that have filled in the neighborhood over the years. Wide vertical boards with narrow battens covering each seam give a home a clean, tailored look that reads as both classic and current. It's a style choice, but on a lot near Bellingham Bay, it's also a functional one: vertical siding sheds water differently than horizontal lap siding, and getting the seam and gap details right matters more here than it would in a dry inland climate.
We install board and batten siding for homeowners throughout Columbia and the surrounding Bellingham neighborhoods, and we do it with one material: James Hardie fiber cement. This page covers what the style needs to hold up against local weather, what a correct installation actually involves, and why hiring a crew that already knows this neighborhood matters as much as the product going on the wall.
The Local Climate Challenge: Salt Air, Driving Rain, and Moss
Columbia's proximity to Bellingham Bay means homes here deal with a steady dose of salt-laden air layered on top of everything else Whatcom County weather brings. That combination is harder on exterior materials than most homeowners expect.
Salt Air
Airborne salt accelerates corrosion on fasteners and metal flashing, and it speeds up the breakdown of paint and factory finishes over time. A board and batten system with dozens of exposed fastener rows — one down each batten — has more places for that process to start than a flat lap siding wall.
Driving Rain
Wind-driven rain off the Sound tests every seam and gap in a wall system, and vertical siding concentrates water flow along the battens and down through the joints behind them. If the drainage path behind those boards isn't built correctly, water finds its way in rather than running off.
A Long Moss Season
Many Columbia lots have mature trees and partial shade, which is great for curb appeal and terrible for siding that can't dry out quickly. Moss and mildew take hold anywhere moisture sits on a surface for extended periods, and a long, damp stretch of the year in Bellingham means siding here needs to shed water and dry fast, not just resist it.
What a Correct Board & Batten Job Actually Involves
Board and batten looks simple from the street, but it's one of the less forgiving siding profiles to install correctly. Most of the problems we get called out to fix on other people's board and batten jobs come down to a handful of details that got skipped.
Rain-Screen Gap and Drainage
A correct installation includes a drainage gap between the siding and the water-resistive barrier underneath — furring strips or a purpose-built rain-screen product — so any moisture that gets past the boards has somewhere to go besides trapped against the sheathing. This detail matters more on a vertical profile than a horizontal one, because water traveling down a batten line has a long, direct path to follow.
Fastening and Batten Spacing
James Hardie specifies fastener type, spacing, and placement for board and batten assemblies, and battens need to land over solid backing, not just decoratively over a seam. Panel and board layout also has to account for expansion and contraction — gaps that are too tight will telegraph stress cracks, and gaps that are too loose let water and wind-driven rain track in.
Flashing, Trim, and Penetrations
Every window, door, hose bib, and vent penetration through a board and batten wall is a potential entry point if it's not flashed correctly. Head flashing above openings, proper kick-out flashing at roof-wall intersections, and correctly lapped house wrap underneath all matter more in a climate with sustained wind-driven rain than they would somewhere drier.
Why We Install Only James Hardie for Board & Batten
We get asked, fairly often, why we don't offer cedar board and batten, vinyl board and batten, or engineered wood products like LP SmartSide. Each of those has a place in the market, and each has real trade-offs that led us to standardize on James Hardie fiber cement instead.
Cedar board and batten looks great new, but it's a wood product in a climate that stays damp for long stretches of the year. It needs regular refinishing to keep water out, it's combustible, and in a shaded, moisture-heavy yard it's exactly the kind of surface that grows moss and holds mildew. Vinyl board and batten is low-maintenance and inexpensive, but the panels are thin, the vertical profile can look visibly flat and plasticky up close, and it doesn't hold paint if a homeowner ever wants to change the color. Primed spruce and engineered wood products can perform well when kept perfectly sealed, but they're more sensitive to moisture intrusion at cut edges and fastener points than fiber cement, and any lapse in maintenance shows up faster.
James Hardie's fiber cement is cement, sand, and cellulose fiber — it doesn't burn, it doesn't rot, and it holds its factory-applied ColorPlus finish far longer than field-applied paint on wood or engineered wood. It's also engineered in HZ5 and HZ10 formulations specifically for wetter, harsher climates, which is the entire reason it's a sensible fit for a bay-adjacent neighborhood like Columbia.
| Material | Moisture Behavior | Maintenance | Fire Rating | Typical Lifespan |
|---|---|---|---|---|
| James Hardie Fiber Cement | Won't rot or swell; engineered for wet climates | Occasional wash; no repainting for years | Non-combustible | 30+ years |
| Cedar Board & Batten | Absorbs moisture; prone to cupping and rot without upkeep | Refinish every 2–5 years | Combustible | 15–25 years with upkeep |
| Vinyl Board & Batten | Sheds water but can trap moisture behind panels | Low; can't be repainted | Combustible, can melt/warp | 15–25 years |
| Engineered Wood (e.g. LP SmartSide) | Sensitive at cut edges and fasteners if seals fail | Repaint and seal-check periodically | Combustible | 20–30 years with upkeep |
Our Installation Process, Step by Step
For a Columbia project, our process is the same whether we're re-siding an older home or finishing new construction:
- Site and moisture assessment — we check existing sheathing, look for signs of past water intrusion, and evaluate shade and drainage patterns specific to the lot.
- Water-resistive barrier and rain-screen setup — correctly lapped house wrap or building paper, plus furring or a rain-screen product to create the drainage gap behind the boards.
- Flashing at every opening — windows, doors, and any penetrations get flashed before a single board goes up.
- Board and batten installation — Hardie boards and battens installed to manufacturer fastening specifications, with layout planned around window and door openings for a clean, consistent look.
- Trim, caulking, and finish check — caulking only where Hardie's specifications call for it (not everywhere, since over-caulking a vertical system can trap water instead of releasing it).
- Final walkthrough — we go over the finished wall with the homeowner before calling the job done.
What a Correctly Installed Job Should Include
- A visible or verifiable drainage gap behind the boards, not boards nailed flat against the barrier
- Fasteners placed and spaced to Hardie's published specifications, not "close enough"
- Head flashing above every window and door, and kick-out flashing where a roofline meets a wall
- Batten layout planned around openings so cuts land in consistent, intentional places
- Caulking limited to the joints Hardie specifies, not applied everywhere as a catch-all
- A factory ColorPlus finish, not field-primed boards waiting on a paint crew
Caring for Board & Batten Siding After Installation
Correctly installed Hardie board and batten doesn't ask for much. An occasional rinse with a garden hose to knock off pollen, road film, or the start of moss growth is usually enough, especially on shaded sections of a home. Homeowners should keep an eye on gutters and downspouts so water isn't sheeting down a wall section repeatedly, and keep vegetation trimmed back a few inches from the siding so airflow can do its job of drying the wall between rain events. Because the ColorPlus finish is factory-applied and baked on, there's no repainting cycle to plan around the way there is with cedar or field-finished wood products.
Why a Bellingham Crew That Knows Columbia Matters
Every neighborhood in Bellingham has its own combination of exposure, tree cover, and drainage quirks, and Columbia's closeness to the bay puts salt exposure and driving rain higher on the list of things to plan around than they'd be further inland. A crew that regularly works this part of town already knows which details — rain-screen gaps, flashing at roof-wall intersections, fastener choices — deserve the most attention on a given lot, and isn't learning those lessons on your project. Permitting and inspection expectations with the City of Bellingham are also more predictable when a contractor already has a track record in the area.
That local familiarity, combined with sticking to one product system we know inside and out, is how we keep board and batten installations consistent from one Columbia home to the next.
