Flounder Bay Board & Batten Siding — Anacortes Install Guide

Board and Batten Near the Water

Flounder Bay sits close to open water on the west side of Anacortes, and that proximity changes what a siding job needs to hold up to. Board and batten is one of the most requested looks in this part of Skagit County — the vertical lines and deep shadow reveals read well against water views and suit the modern farmhouse, coastal, and craftsman styles common on homes in and around the bay. Done correctly, it can look sharp for decades. Done with the wrong material or the wrong install details, it turns into a repaint-and-recaulk chore every few years, right at the point in a house's life where a homeowner least wants to be back on a ladder.

This page covers that one product, in that one setting: what board and batten siding needs to survive near Flounder Bay's salt air and driving rain, what a correct installation actually involves, and why we install this look exclusively in James Hardie fiber cement rather than in wood, engineered wood, or vinyl.

What the Local Climate Does to Vertical Siding

Salt Air

Homes close to Flounder Bay and the surrounding shoreline take on airborne salt that inland Anacortes and Mount Vernon properties mostly avoid. Salt is corrosive to fasteners and can accelerate the breakdown of paint films and caulking. On board and batten specifically, the battens themselves create dozens of extra vertical seams and fastener lines compared to a plain lap siding job — every one of those seams is a place where a poor material or a rushed install shows stress first.

Driving Rain

Storms coming off the Salish Sea don't just fall straight down — wind pushes rain sideways into whatever it hits first, and waterfront and near-waterfront homes get more of that wind-driven rain than sites tucked further inland. Vertical board and batten channels water down the face of the wall differently than horizontal lap siding does, so the flashing details at the top of each panel run and at every window and door opening matter more here, not less.

Moss and Sustained Dampness

Western Washington's long wet season keeps exterior surfaces damp for extended stretches, and shaded north and west walls near tree cover can grow moss and algae if the siding surface and finish don't resist it. Moss holds moisture against the wall longer than it takes to just look bad — it's a maintenance issue with a real path to a moisture problem behind it if it's ignored.

What a Correct Board & Batten Job Actually Involves

The vertical-panel-plus-batten look is simple to picture but easy to get wrong in the field. A correct installation includes:

• A drainage plane and weather-resistive barrier behind the panels, with a rainscreen gap where the assembly calls for one, so any water that gets past the surface has somewhere to go
• Properly lapped and sealed flashing at every window head, sill, and jamb, and at the wall-to-roof intersections common on multi-story bay-facing homes
• Fastener spacing and type matched to the manufacturer's specification, not just "close enough" — corrosion-resistant fasteners matter more this close to salt water
• Battens set to a consistent, engineered-to-spec on-center spacing rather than eyeballed for visual symmetry alone
• Correct clearance at the bottom of the wall above grade, decks, and roof lines so water and moss don't get a foothold at the most vulnerable edge of the siding
• A factory-applied finish system, not a field-applied paint job, wherever the product allows it — field paint is the first thing to fail in a marine climate

Skip any one of these and the wall may still look right for a year or two. The failures that follow — moisture intrusion, fastener staining, panel cupping, caulk lines opening up — usually show up behind the siding before they show up in front of it.

Why We Only Install This Look in James Hardie Fiber Cement

Board and batten can be built in several materials, and we get asked about most of them. Here's our honest read on each, and why we've standardized on one.

Real Wood

Traditional cedar or primed spruce board and batten is the historical original of this look, and it can be beautiful. But solid wood is the material most affected by the exact conditions Flounder Bay has in abundance: sustained moisture, salt air, and long damp seasons. It needs regular repainting, is the most prone to moss and rot at the vulnerable joints between boards and battens, and its lifespan in a marine-adjacent climate is shorter than most homeowners expect going in.

LP SmartSide (Engineered Wood)

Engineered wood siding uses a wood-strand substrate with a resin-treated surface. It performs better than raw lumber but the substrate is still wood-based, meaning any breach in the surface treatment — a fastener hole that wasn't sealed correctly, a cut edge left exposed — gives moisture a path into a material that can swell and deteriorate at that point. In a location with this much sustained dampness, we don't think that's the right trade-off for the life of the siding.

Vinyl Board & Batten

Vinyl versions of this profile exist and cost less upfront. The trade-off is that vinyl is a thin, flexible material — it expands and contracts more with temperature swings, can look visibly less substantial up close than a true panel-and-batten build, and doesn't take paint if a homeowner ever wants to change the color. It also isn't fire-rated the way fiber cement is.

James Hardie Fiber Cement

James Hardie builds this look from HardiePanel vertical siding, engineered specifically for board and batten applications, paired with battens. It's non-combustible, engineered for wet climates through Hardie's HZ5 product line (built for the Pacific Northwest specifically), and finished with the factory-baked ColorPlus finish system rather than field-applied paint — which matters directly for the salt-air and moisture conditions around the bay. It carries a strong transferable manufacturer warranty when installed to Hardie's specification. It's the one system, of the options above, that we're willing to put our name behind for a bay-adjacent home.

Material	Moisture resistance	Salt air durability	Finish	Long-term maintenance
James Hardie fiber cement	Excellent — cement-based, won't rot	Strong when installed to spec	Factory ColorPlus finish	Low — occasional wash
Real wood (cedar/spruce)	Poor to fair — absorbs moisture	Weak — accelerated wear	Field-applied paint/stain	High — repaint every few years
LP SmartSide	Fair — vulnerable at breaches	Moderate	Factory or field finish	Moderate
Vinyl board & batten	Good on the surface, poor at seams	Moderate — can fade/chalk	Color molded in, cannot repaint easily	Low, but limited lifespan

Our Process for a Flounder Bay Board & Batten Job

The process doesn't change dramatically by neighborhood, but the emphasis does. For homes in and around Flounder Bay, we pay particular attention to a few steps:

1. On-site assessment — we look at wall orientation relative to prevailing wind and water, existing moisture damage, current flashing conditions, and how close the home sits to salt spray exposure.
2. Tear-off and sheathing inspection — removing the old siding lets us check the sheathing and framing underneath for hidden rot before anything new goes up. This step is non-negotiable; installing new siding over a compromised wall just hides the problem.
3. Weather barrier and drainage plane — a correctly lapped weather-resistive barrier, with rainscreen furring where called for, goes on before a single panel.
4. Flashing at every penetration — windows, doors, vents, and roof-to-wall intersections all get flashed and sealed before panels close them in.
5. Panel and batten installation to Hardie spec — correct fastener type, spacing, and batten layout, with attention to consistent reveals for the finished look.
6. Final detailing — caulking at trim transitions, touch-up on any field-cut edges, and a clean site when we're done.

Keeping It Looking Right After Installation

A correctly installed Hardie board and batten wall is low-maintenance, not no-maintenance. A short annual routine keeps it performing the way it's designed to:

• Rinse the exterior once or twice a year, more often on shaded walls prone to moss, using a garden hose — avoid high-pressure washing directly into seams
• Check caulking at window and door trim yearly and have any cracked or separated beads redone before the wet season sets in
• Trim back vegetation and tree cover that keeps a wall shaded and damp longer than the rest of the house
• Watch for any staining below fastener heads or at panel joints, which can be an early sign of a flashing or sealant issue worth catching early
• Keep gutters clear so overflow isn't running down the face of the siding during heavy storms

Why a Crew That Already Works This Area Matters

Board and batten done well is a details job, and the details that matter most near Flounder Bay are specific to this stretch of coastline — wind direction, typical storm exposure, how shaded certain lots get, how close a given property sits to salt spray. A crew that has already worked Anacortes and the surrounding Skagit County waterfront isn't guessing at those conditions; they've seen how flashing details, fastener choices, and panel layouts hold up here over time, not just in a manufacturer's general installation guide. That local track record is part of what a homeowner is actually paying for when they hire a siding crew — not just the labor to hang panels, but judgment about how this specific climate treats this specific product.
