Skagit County Board & Batten Siding on March Point: What the Location Actually Demands
March Point sits close to the water on the Fidalgo Bay side of Skagit County, which means homes here deal with a specific combination of exposures that inland Skagit County properties don't face in the same way: salt-laden air rolling off the bay, driving rain that comes in sideways during fall and winter storms, and a moss season that can stretch for months given the amount of shade and moisture the area holds onto. Board and batten siding — with its vertical wide-panel-and-narrow-strip profile — is a strong architectural fit for the refinery-adjacent industrial and rural residential character around March Point, but only if it's built from a material and installed with a system that can actually stand up to what the site throws at it.
This page is specifically about board and batten siding for March Point homes. Not board and batten in general, and not siding in general — this specific profile, in this specific pocket of Skagit County, and what it takes to get it right.
Why Board & Batten Fits This Area
Board and batten reads as a clean, vertical, farmhouse-to-modern profile that works well against the semi-rural, water-adjacent backdrop of March Point. It also has a practical advantage in a salt-air, high-moisture environment: the vertical orientation of the wide boards sheds water down and off the wall plane rather than pooling on horizontal ledges the way some lap profiles can at butt joints. That's a small detail, but on a property that's getting driving rain off the bay several months a year, small drainage details compound over a decade.
The trade-off is that board and batten has more linear seams — the battens themselves — than a standard lap profile. Every batten is a joint, and every joint is a place water can find its way behind the cladding if it isn't fastened, flashed, and gapped correctly. That's the part that separates a board and batten job that looks good for two years from one that performs for twenty.
What Salt Air and Moss Season Do to the Wrong Material
- Untreated or improperly sealed wood substrates absorb moisture at the batten laps and swell, crack, or rot from the inside out.
- Vinyl board and batten can warp or fade faster under UV plus the reflective glare off open water, and it doesn't stop moss and algae from colonizing north-facing and shaded wall sections.
- Moss and lichen growth on any porous or wood-based siding holds moisture against the wall long after the rain has stopped, accelerating rot in a way drier inland Skagit County properties don't experience as fast.
- Salt-laden air corrodes exposed or under-spec fasteners over time, which on a batten profile means the fastening pattern holding the battens themselves is under more long-term stress than people realize.
Why We Only Install James Hardie for This Application
We install James Hardie fiber cement exclusively — we don't do LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar, and on a March Point board and batten job that's not a marketing preference, it's a material decision driven by the site conditions above.
Fiber cement is non-combustible, dimensionally stable in wet-dry cycling, and doesn't feed moss and algae growth the way wood-based products can. James Hardie's ColorPlus factory finish is baked on and warranted against peeling and cracking, which matters a lot in a spot where the finish is going to take a beating from salt air and UV reflection off the water for years without a break. Hardie also engineers specific product lines (their HZ5 line, for example) for harsher climate zones, which is directly relevant to a bay-adjacent property versus a sheltered inland lot.
We're not going to tell you every other product is junk — plenty of homes around the country wear vinyl or wood siding just fine. What we will say is that after years of installing and repairing siding in Skagit County's specific mix of salt air, moss, and driving rain, we made the call to standardize on one material system we can install to spec and warranty with confidence, rather than offer five products and hope each one holds up.
What Correct Board & Batten Installation Actually Involves
Board and batten looks simple from the curb — wide panel, narrow strip, repeat — but the installation sequence is where a job either earns its lifespan or starts failing early.
The Sequence That Matters
- Water-resistive barrier and flashing first. Every penetration, window, and door opening gets flashed and integrated with the weather barrier before a single board goes up. On a salt-air site, this layer is doing more work than usual.
- Rainscreen gap where called for. A furring strip or drainable house wrap behind the siding lets any moisture that does get past the cladding drain and dry instead of sitting against the substrate — important given how long the moss season keeps things damp here.
- Correct board spacing and fastening. James Hardie specifies exact fastener placement, edge distances, and gapping for their board and batten panels. Fastening through both the board and the batten at the right pattern is what keeps the seams tight over decades of wind and moisture cycling.
- Batten placement over — not just beside — the panel joints. The batten's whole job is to cap and protect the seam beneath it. Misaligned battens defeat the purpose of the profile.
- Factory-finished cut edges sealed. Any field-cut edge on a ColorPlus board gets treated with the manufacturer-specified edge sealer so the cut end doesn't become the one spot on the house that absorbs water first.
Common Mistakes We See on Older or Improperly Installed Board & Batten
- Battens face-nailed with no attention to the panel seam alignment underneath.
- No rainscreen or drainage gap on a wall that gets sustained wind-driven rain.
- Caulk used as the primary water-management strategy instead of proper flashing and lap sequencing.
- Cut edges left unsealed, leading to early edge swelling or paint failure right where it's most visible.
Board & Batten Options for March Point Homes
| Consideration | What It Means for This Property |
|---|---|
| Panel width | Wider board spacing reads as more modern/farmhouse; narrower spacing reads more traditional — driven by the home's existing lines and roof pitch |
| Color/finish | ColorPlus factory finish holds up better against salt-air fading and reflective UV off the water than field-applied paint |
| Climate-engineered line | Hardie's harsher-climate product lines are worth discussing directly given the bay exposure, versus their standard line used on more sheltered inland lots |
| Trim integration | Corner boards, window trim, and fascia should be planned as one system with the board and batten field, not added as an afterthought |
Our Process for a March Point Board & Batten Job
We start with a walk of the exterior specifically looking at exposure — which walls take the worst of the bay wind and rain, where moss has already established, and where the existing substrate (if there is one) shows signs of moisture damage. That exposure map drives decisions on rainscreen use, fastening detail, and which Hardie product line makes sense wall by wall, not just for the house as a whole.
From there we handle removal of the old cladding (if applicable), inspection and repair of the sheathing and framing underneath — this step catches problems that are much cheaper to fix before the new siding goes up than after — then weather barrier and flashing, then the board and batten installation itself following Hardie's fastening and gapping specs exactly. We don't shortcut the flashing detail work to save time, because on a site with this much rain and salt exposure, that's the part that determines whether the job is still looking good in fifteen years.
Why a Crew That Already Works March Point Matters
Skagit County isn't uniform. A crew that mostly installs siding on drier, more sheltered inland lots and then takes on a March Point job without adjusting their approach is going to under-detail the flashing and skip the rainscreen decision that a bay-adjacent property actually needs. Working this specific area regularly means we already know which wall orientations take the worst weather, how aggressive the moss growth gets on shaded elevations, and what the salt exposure does to fasteners and finishes over time — so those factors get built into the plan from day one instead of getting discovered as a callback five years later.
It also means we're not guessing at permitting or inspection expectations for the area, and we're realistic with clients about timeline around the wetter months rather than promising a schedule that weather is going to blow up.
What This Costs to Think About
We're not going to publish a fake price list — every home's substrate condition, square footage, trim complexity, and story height change the number. What we can tell you honestly is that board and batten with proper flashing, rainscreen detailing where warranted, and full trim integration costs more upfront than a bare minimum lap-siding reside, and that the difference shows up as the years pass rather than on day one. On a property taking direct salt air and driving rain, spending correctly on the water-management details the first time is cheaper than a partial reside and a moisture repair five years in.
