Anacortes Siding Similk Beach sits close enough to the water that its siding lives a different life than siding a mile or two inland in Anacortes. This page walks through what that means for a board and batten installation specifically: what the climate does to the seams and finish, what a correct install looks like underneath the boards, and why the crew you hire for it matters as much as the material.
Similk Beach Sits Right in the Weather
Similk Beach's homes face Similk Bay and the open water beyond it, which means siding here takes a harder hit than siding a few miles inland in Anacortes. Salt-laden air corrodes fasteners and hardware faster than it does on a sheltered lot, wind-driven rain gets pushed sideways into every seam and joint, and Skagit County's long wet season keeps north-facing and water-facing walls damp enough, long enough, for moss and algae to take hold. None of this is unique to Similk Beach, but it's more pronounced there than almost anywhere else we work.
Board and batten siding, with its vertical boards and raised seams, has more joints and more surface texture than a flat lap profile, which means more places for water to find a way in if the installation isn't done right, and more places for moss to grip if the material and finish aren't up to it. Getting board and batten right in a place like Similk Beach isn't about the aesthetic choice; it's about the build details underneath it.
What Board & Batten Siding Is, and Why Homeowners Choose It
Board and batten is a vertical siding style built from wide flat panels or boards with narrower strips, the battens, covering the seams between them. It reads as a clean, linear, farmhouse-to-modern look that a lot of Pacific Northwest waterfront and shoreline homes use for at least an accent wall, a gable, or a full elevation. It also pairs well with horizontal lap siding on the same house, which is a common combination on Fidalgo Island homes that want visual contrast between stories or wings.
Why It Behaves Differently Than Lap Siding
Lap siding sheds water down and off in overlapping courses. Board and batten relies on the batten itself, and the flashing and drainage plane behind it, to keep water from tracking sideways into the seam and behind the panel. That difference matters more in a driving-rain, salt-air environment than it does in a dry, sheltered one; the margin for error is smaller, and it shows up sooner when the installation isn't right.
Why the Material Underneath the Look Matters More Here
Board and batten can be built out of several materials, and in a marine climate the material choice affects how long the seams, the fasteners, and the finish actually hold up, not just how the house looks the day it's installed.
| Material | How It Handles Salt Air & Driving Rain | How It Handles a Long Moss Season |
|---|---|---|
| Vinyl board & batten | Battens are often hollow trim pieces; seams can flex and open over time in wind | Surface texture and expansion joints give moss and algae places to establish |
| Cedar board & batten | Absorbs moisture at end grain and seams; needs consistent refinishing to stay sealed | Organic material feeds moss and mildew faster once the finish wears |
| Primed spruce / engineered wood | Vulnerable at cut edges and fastener points if the factory seal is breached | Similar moisture-driven risk to cedar if maintenance lapses |
| James Hardie fiber cement | Non-combustible, dimensionally stable board that doesn't expand and contract with moisture the way wood does | Factory ColorPlus finish resists the buildup that gives moss a foothold |
We install James Hardie exclusively, and this is a direct reason why. A board and batten wall is mostly seams and edges, the parts of any siding system most exposed to weather, and we'd rather build that wall out of a material engineered to hold its shape and finish in wet, salty conditions than one that needs the homeowner to stay ahead of maintenance to avoid problems. Vinyl and engineered wood board and batten both have their place; we simply don't think either one is the right call for a wall that faces the kind of exposure Similk Beach gets.
What a Correct Board & Batten Installation Involves
The Drainage Plane and Rainscreen Gap
Behind every board and batten wall we install, there's a weather-resistive barrier and a rainscreen gap that lets any moisture that does get past the siding drain and dry out instead of sitting against the sheathing. On a Similk Beach lot exposed to wind off the water, this detail is not optional; it's the difference between a wall that dries out after a storm and one that stays damp long enough to start causing problems behind the siding.
Fasteners and Flashing
Salt air is hard on fasteners. We use fasteners and flashing rated for the exposure, placed and spaced to Hardie's installation specifications rather than shortcuts that save an hour on a long wall. Flashing at every horizontal transition, window, and roofline is what actually keeps wind-driven rain from getting behind the panel in the first place.
Batten Layout and Spacing
Batten spacing is partly aesthetic and partly structural; inconsistent spacing or under-fastened battens are one of the more common board and batten failures we see when we tear off older siding. We lay out and fasten battens to hold their line over the life of the house, not just to look right on install day.
Corners and Trim
Outside corners on a board and batten wall take a lot of visual attention and a lot of weather at the same time, since they sit at the edge of the wall plane and catch wind-driven rain from more than one direction. We detail corners and trim transitions to shed water the same way the field of the wall does, so the corner isn't the first place the siding starts to fail.
The James Hardie System We Use for This Look
For board and batten, that typically means Hardie panel siding with Hardie trim battens over it, finished in ColorPlus, Hardie's factory-applied finish, backed by its own finish warranty, rather than a field-applied paint job that starts weathering the moment it's exposed. Hardie's HZ10 product line is engineered for the wetter, more humid climate zone that includes the Pacific Northwest coast, which is the version we use on Skagit County homes rather than a formulation built for a drier region.
This isn't a marketing detail; it's the reason the boards, the battens, and the finish are all still doing their job ten and twenty years out, on a wall that spends its life a short walk from saltwater. Hardie's warranty coverage is also transferable if the home sells, which matters more on a shoreline property that tends to turn over as a vacation or retirement home.
Our Process on a Similk Beach Job
- Walk the exterior and assess current siding, moisture history, and any soft sheathing or trim before quoting anything.
- Confirm the board and batten layout and reveal with the homeowner: where it runs, where it meets lap siding or trim, and how it wraps corners.
- Remove old siding and inspect and repair sheathing, then install or verify the weather-resistive barrier and rainscreen.
- Install Hardie panels and battens to manufacturer fastening and flashing specifications, with extra attention at window heads, roof-wall intersections, and any wall facing the water directly.
- Caulk and finish per Hardie and ColorPlus specifications, then walk the finished job with the homeowner before we consider it done.
What It Costs and What Drives the Price
Board and batten generally costs more per square foot than plain lap siding, mainly because of the batten material and the added trim labor, not the panel itself. On a Similk Beach project specifically, a few local factors move the number more than they would on an average inland Anacortes job.
| Cost Factor | Why It Matters on a Similk Beach Home |
|---|---|
| Tear-off vs. install over existing siding | Waterfront homes more often need a full tear-off to check for hidden moisture damage first |
| Wall exposure and elevation | Water-facing walls typically get upgraded flashing and fastening details, which adds labor |
| Batten spacing and trim complexity | Tighter batten spacing and more corners and trim transitions add material and install time |
| Site access | Steep or narrow waterfront lots can slow staging and material handling |
| Sheathing repair | Any rot or soft sheathing found at tear-off needs to be replaced before siding goes back on |
We give a firm number after that first walk-through, not a phone estimate. On a board and batten job especially, the sheathing condition and wall exposure matter too much to guess at from a photo, and a fair price depends on what we actually find once the old siding comes off.
Living With Board & Batten in a Salt-Air, Moss-Prone Climate
A correctly installed Hardie board and batten wall doesn't need much from a homeowner, but a little seasonal attention keeps it looking and performing the way it should.
- Rinse salt spray and grime off exterior walls a couple of times a year, especially on water-facing elevations.
- Keep gutters and downspouts clear so roof runoff isn't dumping extra water down a batten wall.
- Trim back vegetation and branches that shade a wall and keep it damp longer after rain.
- Check caulking at trim and window transitions annually and have any gaps resealed before winter.
- Address any moss or algae on adjacent surfaces, roof, walkways, decking, promptly so it doesn't spread onto the siding.
Why a Crew That Already Works Similk Beach Matters
Anacortes and the surrounding Skagit County shoreline communities don't all get weather the same way. A crew that's worked Similk Beach knows which walls take the worst of the wind and rain, how the moss season here compares to a more sheltered Anacortes lot a mile inland, and what it actually takes, in flashing, fastening, and sequencing, to build a board and batten wall that holds up to it. That's a different starting point than a crew pricing the job from a set of general specs with no sense of how this particular stretch of coastline behaves, and it shows in how the wall performs five and ten winters later.
