Bellingham Exterior Board & Batten Siding in Bellingham's Columbia Neighborhood
Board and batten siding has become one of the most requested exterior looks in Bellingham, and the Columbia neighborhood is no exception. The vertical lines read as clean and modern on newer builds, and they pair naturally with the craftsman and cottage-style homes that make up a lot of Columbia's older housing stock. But the look is only half the job. In a neighborhood this close to Bellingham Bay, board and batten siding has to hold up to salt-laden air, sideways rain off the water, and a moss season that can run eight months of the year. Get the material or the install wrong and you're looking at swollen battens, streaking, and rot behind the boards within a handful of years. Get it right, and it's one of the lowest-maintenance, longest-lasting siding profiles you can put on a house.
We install James Hardie fiber cement exclusively, and board and batten is one of the applications where that decision matters most. This page covers what Columbia homes specifically need from a board and batten system, what a correct installation actually involves, and how we run the job from estimate to final walk-through.
Why Columbia's Climate Is Hard on Vertical Siding
Board and batten siding is a vertical-panel system with narrow strips (battens) covering the seams between wider boards or panels. That seam geometry is exactly where water problems start if the material or the installation isn't right. A few things about Columbia's exposure make this a bigger deal than it would be in a drier inland climate:
- Salt air corrosion: Proximity to Bellingham Bay means airborne salt reaches fasteners, trim, and any exposed metal. Fastener choice and flashing details matter more here than they would 20 miles inland.
- Driving rain: Storms coming off the water don't fall straight down — wind pushes rain sideways into vertical seams and under battens. Every gap and joint needs to shed water outward, not trap it.
- Moss and algae season: Whatcom County's damp, mild winters and shoulder seasons are ideal moss and mildew conditions. Anything that stays wet for long stretches — wood battens especially — becomes a growth surface, which then holds even more moisture against the siding.
- Freeze-thaw cycling: Bellingham doesn't see deep freezes often, but it gets enough freeze-thaw swings each winter that any siding holding moisture will eventually crack, cup, or delaminate.
None of this is unique to Columbia specifically — it's a Whatcom County coastal reality — but Columbia's mix of older wood-sided homes and newer infill construction means we see the full range of what happens when board and batten is done with the wrong material or a rushed install.
What Correct Board & Batten Installation Involves
The visual appeal of board and batten is simple, but the assembly underneath is not. A correct install has several layers working together, and skipping any one of them is where failures start.
Weather-Resistive Barrier and Drainage Plane
Before any siding goes up, the wall needs a continuous weather-resistive barrier with properly lapped and taped seams. On a vertical siding system, we also install a drainage gap — typically a furring strip or purpose-built rainscreen product — behind the panels. This gives any moisture that gets past the siding a path to drain and dry out instead of sitting against the sheathing. This step matters more in Bellingham's climate than in drier regions, and it's one of the first things we check when we're asked to look at a failing board and batten job.
Panel and Batten Fastening
Fasteners need to be corrosion-resistant — stainless steel or hot-dipped galvanized, not standard coated fasteners that will corrode faster in salt-influenced air. Fastener spacing and placement follow the manufacturer's engineering specs, not a "close enough" pattern. Over-driven or under-driven fasteners are one of the most common causes of early siding failure we find on inspections.
Flashing at Every Penetration
Windows, doors, hose bibs, light fixtures, and vents all break the plane of the siding, and every one of those penetrations needs proper flashing integrated with the weather barrier. Vertical siding is less forgiving of flashing shortcuts than horizontal lap siding, because water runs down the face of the wall and hits every seam directly.
Caulking and Joint Treatment
Board and batten has more vertical seams than most siding profiles. Joints need the right sealant, applied correctly, at butt joints and terminations — not as a substitute for proper flashing, but as the final line of defense.
Why We Use James Hardie for Board & Batten, Specifically
Board and batten can be built from several materials, and we've installed or inspected most of them. Here's the honest comparison, framed around why fiber cement is what we put on Columbia homes:
| Material | Behavior in Bellingham's Climate | Long-Term Maintenance |
|---|---|---|
| Solid wood (cedar/spruce) | Attractive, but absorbs moisture readily; prone to cupping, splitting, and moss growth in constant damp conditions | Repainting/staining every few years; caulk and board replacement over time |
| Vinyl | Sheds water on the surface but seams and battens are often just cosmetic overlays; can warp in temperature swings and doesn't hold paint if you want to change color later | Low, but limited lifespan and repair options; cracks in impacts |
| LP SmartSide (engineered wood) | Wood-based core is more moisture-sensitive than fiber cement; edge sealing and gap maintenance are critical in a wet climate like this one | Requires diligent caulk and touch-up maintenance to avoid swelling at cut edges |
| James Hardie fiber cement | Non-combustible, dimensionally stable, engineered for coastal Pacific Northwest exposure (HZ5/HZ10 product lines); resists moisture-driven swelling and doesn't feed moss the way wood does | Occasional wash-down; factory ColorPlus finish holds color far longer than field-applied paint |
We're not going to tell you wood board and batten can't look great — it can, for a while. But we've pulled enough failed wood and engineered-wood siding off Whatcom County homes to know what this climate does to organic and moisture-sensitive materials over a 10-15 year span. James Hardie's fiber cement doesn't absorb water into its core the way wood-based products do, it won't rot, and it carries a warranty structure built around long-term performance rather than best-case conditions. That's why it's the only board and batten material we install.
Color and Finish Options for Board & Batten
James Hardie's ColorPlus factory finish is baked on and backed by a dedicated finish warranty, which matters on a profile with this many seams and cut edges. For Columbia homes, we most often see two approaches:
- Full board and batten facade: A single accent wall, gable, or entire elevation done in vertical panel-and-batten for a modern or farmhouse look.
- Mixed profile: Board and batten on gables or upper stories paired with lap siding below — a common combination on both newer Columbia builds and updated older homes.
Color choice in a marine climate isn't purely aesthetic — darker colors absorb more heat and can accelerate wear on lesser products, though this is far less of a concern with Hardie's engineered finish than with field-painted wood. We'll walk through the ColorPlus palette during your estimate and talk through what tends to hold up best given your home's sun exposure and surrounding tree cover.
Our Process for Columbia Board & Batten Projects
We work Columbia and the surrounding Bellingham neighborhoods regularly, which means we already know the housing stock, the typical wall assemblies, and the drainage challenges specific to homes near the bay. Our process:
- On-site assessment: We inspect existing siding, sheathing condition, and any moisture damage before quoting anything. On older Columbia homes, this step often catches issues that need addressing before new siding goes up.
- Detailed estimate: A written scope covering material, drainage plane, flashing details, and fastening — not a vague square-footage number.
- Prep and weather barrier install: Removal of failing siding, sheathing repair if needed, and a properly lapped weather-resistive barrier with rainscreen gap.
- Panel and batten installation: Installed to James Hardie's fastening and clearance specifications, with corrosion-resistant fasteners throughout.
- Flashing and sealant detail work: Every window, door, and penetration flashed and sealed correctly before final trim.
- Final walk-through: We go over the finished work with you directly and address anything before we consider the job done.
What to Check Before You Hire Anyone for This Job
Board and batten failures are almost always installation failures, not material failures — which means the crew matters as much as the product. Before hiring for a board and batten project in Columbia or anywhere in Bellingham, ask:
- Do they install a drainage plane/rainscreen behind vertical siding, or panels direct-to-sheathing?
- What fastener type do they use, and is it rated for coastal/marine exposure?
- Are they James Hardie certified installers, and do they follow the manufacturer's published fastening and clearance specs?
- Will flashing details be shown to you, not just described?
- Does their warranty cover installation workmanship separately from the manufacturer's material warranty?
A crew that already works Columbia and the greater Bellingham area will know the difference between a wall assembly on a 1920s home near the older parts of the neighborhood and one on a recent infill build — and will adjust the moisture management approach accordingly instead of using one generic method everywhere.
