Lynden Siding Why Board & Batten Fits Homes in Blaine
Board and batten has become one of the most requested siding profiles in Whatcom County, and Blaine's mix of older farmhouses, newer builds near the water, and everything in between is a good match for it. The vertical lines read as clean and modern on a contemporary build, but the same profile also feels right at home on a traditional gable-front house. It's a look that works on a full exterior or as an accent on a gable end, a porch wall, or a dormer next to lap siding.
But the reason we bring it up as a dedicated service — rather than lumping it in with general siding replacement — is that board and batten is installed differently than lap siding, and it has to be installed correctly to hold up where Blaine sits: close to the water, exposed to wind-driven rain, and shaded enough in places to grow moss most of the year.
What Blaine's Climate Does to a Vertical Siding Profile
Blaine's proximity to the water means homes here deal with salt-laden air on top of everything else Whatcom County throws at an exterior. Salt air accelerates corrosion on exposed metal — fasteners, flashing, hose bibs, light fixtures — faster than it does even a few miles inland. On a board and batten wall, every batten strip is attached with its own line of fasteners, which means there's simply more hardware exposed to that air than on a standard lap job.
Driving rain is the second factor. Board and batten creates vertical seams every 12 to 16 inches, and each one of those seams is a place water can be pushed by wind if it isn't detailed correctly. On a lap profile, gravity does most of the work moving water down and off the wall. On a vertical profile, the water-resistive barrier and flashing behind the boards are doing more of that work, so the assembly behind the siding matters more than it does with lap.
Then there's moss. Whatcom County's damp, mild winters and long shoulder seasons keep shaded wall sections wet for extended stretches, and moss and algae will colonize any siding material that stays damp long enough — cement, wood, or vinyl. It's mostly a cosmetic issue, but on a batten strip with tight reveals, it also traps additional moisture against the wall if it's left to build up.
What a Correct Board & Batten Installation Actually Involves
The Assembly Behind the Boards
A board and batten wall that holds up in this climate isn't just panels and battens face-nailed to the studs. It starts with a properly lapped water-resistive barrier, flashing at every window, door, and penetration, and — on most jobs we do here — a rainscreen gap behind the siding so any moisture that does get past the outer layer has somewhere to drain and dry out instead of sitting against the sheathing.
Panel and Batten Layout
We lay out batten spacing before the first panel goes up, not as an afterthought once panels are hung. Batten spacing has to line up with the panel seams underneath, land on framing for a solid fastening pattern, and stay consistent around corners, windows, and under eaves. Uneven spacing is one of the fastest ways to make an otherwise good installation look sloppy.
Fastening and Flashing Details
Every seam gets caulked or covered per the manufacturer's spec, not just where it's visible. Fasteners get set to the correct depth — overdriven nails crack fiber cement and create a point where water works its way in. Given the salt air here, we also pay attention to fastener material; corrosion-resistant fasteners cost a little more up front and save a callback in five years.
Why We Install James Hardie Fiber Cement — Not Vinyl, LP, or Cedar
Board and batten is available in several materials, and each one has a real argument for it. Vinyl board and batten is inexpensive and low-maintenance in the sense that it never needs painting, but it's also thin, it expands and contracts more with temperature swings, and it doesn't hold up as well to wind-driven rain finding its way behind loose panels. LP SmartSide is a strand-based engineered wood product that's easier and lighter to install than fiber cement, but it's still wood at its core, and wood-based siding depends heavily on caulking and flashing staying perfect over time — something that's harder to guarantee in a climate that stays damp as long as this one does. Cedar board and batten looks excellent when it's new, but it needs regular refinishing to keep that look and to keep moisture out, which is a real ongoing cost most homeowners underestimate when they price the project.
We standardized on James Hardie fiber cement for a reason: it's non-combustible, it's engineered for the Pacific Northwest's wet climate under Hardie's HZ5 product line, it holds its factory-applied ColorPlus finish for years without repainting, and it comes with a strong, transferable warranty. It doesn't rot, it doesn't attract insects, and it handles the freeze-thaw and moisture cycles Whatcom County sees every winter better than the alternatives we've worked with. That's not a knock on every other product — it's why we've chosen to install this one exclusively.
Our Process, Start to Finish
- Walk the exterior with you — we look at existing siding condition, trim, water damage history, and any areas that show moss or staining, since those often point to a drainage or moisture issue worth addressing during the tear-off.
- Measure and quote — we give you a written estimate that breaks out material, labor, and any trim or flashing work separately, so you know what you're paying for.
- Remove old siding and inspect sheathing — this is where hidden rot or water damage shows up, and we flag it before covering it back up rather than after.
- Install the water-resistive barrier, flashing, and rainscreen — the part of the job nobody sees but that determines how the wall performs for the next 20-plus years.
- Hang panels and battens — set to spec fastening pattern, spacing, and reveal.
- Caulk, touch up, and final walkthrough — we go over the finished wall with you before we call the job done.
What Board & Batten Costs to Install in Blaine
Board and batten typically costs somewhat more per square foot than standard lap siding, mostly because of the extra material (battens on top of panels) and the additional labor to lay out and fasten two layers instead of one. The table below covers the factors that move the price on a real project — we'll walk through all of these on the estimate.
| Cost Factor | Why It Matters |
|---|---|
| Home size and wall complexity | More corners, gables, and dormers mean more cuts, more batten layout, and more labor hours |
| Existing siding removal | Tear-off and disposal of old siding adds cost versus installing over new construction |
| Sheathing repair | Rot or water damage found during tear-off has to be repaired before new siding goes on |
| Trim and window detail | More window and door openings mean more flashing and trim work per square foot of wall |
| Story height and access | Second-story and steep-site work requires more scaffolding and takes longer |
| Color and finish | Factory-finished ColorPlus panels cost more up front than field-painted but skip a repaint cycle |
Maintenance Board & Batten Needs in This Climate
Fiber cement is genuinely low-maintenance, but "low" isn't "none," especially in a climate that stays damp as much of the year as Whatcom County's does. A short annual routine keeps a board and batten wall looking good and catches small problems before they become expensive ones.
- Rinse the exterior once or twice a year to knock down early moss and algae growth before it takes hold, especially on shaded and north-facing walls
- Check caulking at seams, windows, and corners for cracking or gaps, particularly after the first winter
- Look at exposed fasteners and metal flashing for early rust or staining, given the salt air in this area
- Keep gutters clear and downspouts directed away from the wall so runoff isn't constantly hitting one section of siding
- Trim back landscaping and tree cover that keeps a wall section shaded and damp longer than the rest of the house
- Address any soft spots, staining, or visible gaps promptly rather than waiting for the next scheduled maintenance
Why a Crew That Already Works Blaine Matters
Board and batten is less forgiving of shortcuts than lap siding, and a crew's experience with this specific profile in this specific climate shows up in the details — batten spacing that's consistent across a whole elevation, flashing that's actually detailed for driving rain rather than just caulked over, and fastener choices that account for salt air instead of using whatever's on the truck. Our crew is based out of Lynden and works throughout Whatcom County, including Blaine, so we're familiar with the moisture and salt-air conditions here and we don't have to relearn them on your house.
We also know the practical side of working in this area — permitting expectations, typical weather windows for exterior work, and what tends to go wrong on homes exposed to wind off the water. That's the kind of thing that only comes from doing the work locally and repeatedly, not from a crew passing through the area for one job.
