Anacortes Window Similk Beach's Climate Is Harder on Siding Than It Looks
Similk Beach sits close enough to the water that homes there deal with a different set of stresses than a house a few miles inland in Anacortes proper. Salt-laden air moves through constantly, driving rain comes in sideways off the water during winter storms, and the shaded, damp stretches of the property stay wet long after a storm has passed. Add in Skagit County's long moss season — often eight or nine months out of the year — and you have a climate that quietly tests every seam, joint, and fastener on a home's exterior.
Board and batten siding is a popular style out here because it reads as clean, vertical, and a little more coastal-cottage than standard lap siding. But the same features that make it attractive — narrow reveals, vertical seams, a batten strip covering every joint — also make it less forgiving of a sloppy install. Get the moisture management wrong on a board and batten job, and problems show up faster here than almost anywhere else in the county.
Why Board & Batten Fits Similk Beach Homes
The look homeowners want
Board and batten gives a home strong vertical lines, deep shadow lines at every batten, and a texture that pairs well with the mix of traditional and modern coastal homes around Similk Beach. It works well as a full exterior treatment or mixed with a horizontal lap on gables, entries, or accent walls.
Why it behaves differently than lap siding
Lap siding sheds water by design — each course overlaps the one below it. Board and batten relies on the seams between panels being sealed and covered correctly, and on the battens themselves being fastened in a way that doesn't trap water behind them. In a climate with this much driving rain, that difference matters. A board and batten wall with even one poorly flashed seam can pull moisture behind the panel for months without an obvious sign from the outside — until paint starts failing, or the substrate behind it starts to swell.
The James Hardie Board & Batten System We Install
We install James Hardie fiber cement exclusively — we don't run vinyl, LP SmartSide, Cemplank, Allura, primed spruce, or cedar board and batten crews. For a style this dependent on getting joints and moisture detailing right, we want a product with a fiber cement's dimensional stability and a factory finish that isn't relying on field-applied paint to hold up its end of the job.
Panel and batten system
Hardie's vertical siding panels are installed with true wood-look battens over the joints, giving the same shadow-line look as traditional board and batten but with a non-combustible, fiber cement substrate underneath. The panels are engineered to resist swelling, cracking, and moss growth better than wood-based alternatives — a meaningful advantage given how long moss season runs here.
ColorPlus factory finish
Where budget allows, we recommend Hardie's ColorPlus finish — a factory-applied, baked-on finish that's more consistent and more weather-resistant than a field-painted finish, and comes with its own finish warranty. In a salt-air environment, reducing the number of field-painted surfaces reduces the number of things that can fail early.
What a Correct Board & Batten Installation Involves
Most board and batten problems we get called to look at aren't product failures — they're installation shortcuts. On a home this close to the water, none of the following steps are optional:
- A proper weather-resistive barrier behind every panel, lapped correctly at every seam and penetration
- A rainscreen or drainage gap so any moisture that does get behind the siding can actually drain and dry instead of sitting against the wall sheathing
- Correct fastener type and spacing — in a salt-air zone, corrosion-resistant fasteners aren't a nice-to-have, they're the difference between staining and streaking within a few years or not
- Sealed and flashed panel joints, not just caulked and hoped-for
- Kickout flashing at every roof-to-wall intersection so roof runoff is diverted away from the siding instead of running down behind it
- Correct clearance between the bottom of the siding and grade, decks, or patios, so splash-back and standing water don't sit against the panel edge
- Battens fastened through to framing where required, not just face-nailed into the panel
Every one of these is invisible once the job is finished and painted. That's exactly why it matters who does the work, not just what product goes on the wall.
Board & Batten Options: How They Hold Up in This Climate
| Material | Moisture behavior | Salt-air / corrosion resistance | Moss & mildew resistance | Finish |
|---|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable, does not swell or rot | Non-combustible substrate; corrosion risk limited to fasteners/trim if wrong type used | Resists moisture absorption that feeds moss and mildew growth | Factory ColorPlus or field paint |
| Vinyl board & batten | Can warp or buckle with heat/cold cycling; joints rely on interlocking, not sealing | Not affected by salt corrosion itself, but fades and becomes brittle over time | Moss/mildew grow on the surface film if not cleaned | Color molded in, cannot be repainted easily |
| LP SmartSide (wood-strand) | Engineered wood — vulnerable if moisture gets behind panels or seams fail | Fasteners and cut edges need diligent sealing near salt air | Wood-based substrate is more susceptible if finish is compromised | Factory primed or prefinished, needs maintenance |
| Cedar board & batten | Natural wood movement; seams and battens need regular re-caulking | Handles salt air reasonably but needs consistent maintenance | Prone to moss and mildew without regular cleaning/treatment | Stain or paint, ongoing upkeep |
This isn't a knock on any of these products used correctly in the right setting — it's why we standardized on Hardie for the conditions we actually work in around Similk Beach and the rest of Anacortes.
What Drives the Cost of a Board & Batten Job
| Factor | Why it matters |
|---|---|
| Wall complexity | Gables, dormers, and multiple roof-to-wall intersections mean more flashing and cutting |
| Existing siding removal | Tear-off and sheathing inspection/repair adds time versus a clean substrate |
| Water damage found underneath | Common on waterfront-adjacent homes — rot repair is priced once the old siding is off and the sheathing is visible |
| Finish choice | Factory ColorPlus vs field-applied paint changes both material cost and long-term maintenance |
| Batten spacing/pattern | Tighter reveals and custom spacing take more layout and labor time |
| Trim and accent detailing | Window and door trim, corner treatments, and mixed siding styles add labor |
Our Process for Similk Beach Jobs
We start with a walk-around of the home, looking specifically at water exposure — which walls take the worst of the driving rain, where roof runoff lands, and where moss and moisture already show on the current siding or trim. From there we put together a scope that covers tear-off, any sheathing repair, the weather-resistive barrier and drainage plane, and the Hardie panel and batten install itself. We give a written estimate before any work starts, and we don't treat flashing and drainage detailing as an upsell — it's part of doing the job correctly the first time, especially this close to the water.
Questions to Ask Before Hiring a Board & Batten Crew
- Do they install a rainscreen or drainage gap, or just nail panels straight to the weather barrier?
- What fastener type do they use, and is it rated for a salt-air environment?
- Will they show you the flashing details at roof-to-wall intersections before they're covered up?
- Do they inspect and repair sheathing before re-siding, or just cover what's there?
- Is the warranty from the manufacturer, the installer, or both — and what does it actually cover?
- Have they worked in your specific neighborhood before, and do they understand its exposure?
Why a Crew That Already Works Similk Beach Matters
A siding crew that mainly works inland neighborhoods doesn't always think about kickout flashing, drainage planes, or fastener corrosion the same way a crew that works Similk Beach and the rest of the water-facing side of Anacortes does. We've seen what happens when board and batten goes up without a drainage gap in a home that takes direct rain off the water, and we've seen how long a correctly detailed Hardie installation holds up under the same conditions. That local track record shapes how we scope and install every job out here, not just the ones on the water.
