Board & Batten Siding, Built for Where Marietta Actually Sits
Marietta sits close enough to Bellingham Bay and the water that its homes take a different kind of weathering than houses ten miles inland. Salt-laden air moves through the neighborhood on a regular basis, driving rain comes in sideways off the water during winter storms, and the tree cover that makes the area attractive also means long stretches of shade where moss and algae get a foothold on siding and never really let go. Board and batten siding — with its bold vertical lines and deep shadow lines — is one of the most requested looks for homes in this part of Fairhaven, and when it's built with the right material and the right detailing, it holds up to all three of those conditions. When it's built wrong, it's one of the first styles to show problems, because the vertical battens and the seams behind them are exactly where water finds its way in.
This page is about doing board and batten right for a Marietta home specifically — not board and batten in general. The климate here isn't hypothetical; it's the reason certain shortcuts that work fine in a drier part of the state don't work fine fifteen minutes from the bay.

Why Board & Batten Is a Different Installation Than Lap Siding
Board and batten isn't just a style choice — it changes how the whole wall assembly has to be built. Instead of overlapping horizontal boards that naturally shed water downward, board and batten relies on vertical boards (or a base panel) with narrower battens covering the seams between them. That means:
- Every vertical seam is a potential water path if it's not flashed and fastened correctly.
- The battens themselves need consistent spacing and fastening or they telegraph unevenness that's very visible in raking light.
- There's more end-grain and more cut edges exposed per square foot than with a standard lap pattern, and cut edges are where fiber cement is most vulnerable if they're not sealed.
- Drainage behind the siding matters more, because vertical panels don't have the built-in overlap that sheds water the way horizontal lap does.
None of that is a reason to avoid the style — board and batten is a proven, durable look when it's installed correctly. It's a reason to be picky about who installs it, especially this close to the water.
What "Correct" Actually Means Behind the Battens
A correct board and batten install starts with a drainage plane — a weather-resistant barrier installed behind the siding with a gap that lets any moisture that gets past the cladding drain and dry out instead of sitting against the sheathing. On top of that, every seam, window, and door opening gets flashed so water is directed out and down, never trapped. The battens go on with fasteners sized and spaced to manufacturer spec, not just "close enough," and every field-cut edge — at corners, around trim, at penetrations — gets factory or field-applied sealant so raw material is never left exposed to the weather. Skip any one of these steps and the siding might look fine for a year or two before the moisture behind it starts telling a different story.
Why We Only Install James Hardie for This Style
Board and batten gets specified in a lot of materials — vinyl, engineered wood, primed cedar, various fiber cement brands — and we've made a deliberate call to install James Hardie fiber cement and nothing else, on this style in particular as much as any other.
| Material | Why it's a harder sell for Marietta's climate |
|---|---|
| Vinyl board & batten | Thin profile flexes and shows waviness in the vertical battens; seams and corner posts are more exposed to wind-driven rain; doesn't hold paint if the color needs to change later. |
| Primed or unprimed cedar | Real wood grain is attractive but demands ongoing refinishing to resist moss, and cut battens are prone to cupping and checking in a wet, shaded climate. |
| Engineered wood (OSB-based) | Performs well when detailed and maintained precisely, but the wood-strand core is unforgiving of long-term moisture exposure if a seam or fastener point ever fails. |
| James Hardie fiber cement | Non-combustible, dimensionally stable in wet-dry cycling, factory-applied ColorPlus finish resists the fading and moisture uptake that raw or field-painted material doesn't. |
Fiber cement doesn't warp, cup, or swell the way wood-based products can when they take on repeated moisture, and it doesn't flex and telegraph waviness the way thin vinyl profiles do in a vertical pattern. Hardie's HZ5 product line is engineered for climates that see extended wet weather, which describes Whatcom County's fall through spring stretch about as well as any region in the state. We're not installing it because it's the only material capable of board and batten — we're installing it because, on the balance of moisture behavior, appearance retention, and long-term maintenance, it's the one we're willing to put our name behind here.
What Salt Air and Moss Season Actually Do to Board & Batten
Salt Air
Airborne salt from the bay settles on exterior surfaces and accelerates corrosion on anything metal — fasteners, flashing, trim accessories. It can also degrade certain paint and coating systems faster than they'd wear inland. This is why fastener choice and flashing material matter as much as the siding itself; a beautiful board and batten job undermined by the wrong fastener spec will show rust streaking down the battens within a few years.
Driving Rain
Storms coming off the water don't fall straight down — they hit walls at an angle, which pushes water into seams and laps that would stay dry in a calmer climate. Board and batten's vertical seams are more exposed to this than horizontal lap, which is exactly why the drainage plane and flashing details behind the boards aren't optional extras — they're the difference between a wall that sheds wind-driven rain and one that slowly absorbs it.
Moss and Algae
Shaded, moisture-retaining spots on a Marietta property are where moss gets its start, and once established it holds water against the siding surface far longer than open sun-exposed walls do. A factory-applied finish that resists moisture uptake — rather than a porous or absorbent surface — makes a real difference in how long it takes moss and algae to gain a foothold, and how easy the siding is to clean when they do.
Our Process for a Marietta Board & Batten Job
- On-site assessment. We look at existing siding, sheathing condition, moisture history, sun/shade exposure, and how exposed the home is to prevailing wind and rain direction.
- Tear-off and sheathing check. Old siding comes off and we inspect the sheathing underneath for rot or existing moisture damage before anything new goes up — this step gets skipped by crews trying to move fast, and it's the single biggest predictor of a callback down the road.
- Weather-resistant barrier and drainage plane. Installed correctly with proper overlap and integrated flashing at every penetration, window, and door.
- Board and batten installation. Hardie panel or plank base installed to spec, battens fastened at correct spacing, all field cuts sealed.
- Trim, flashing, and caulking detail work. This is where a lot of the long-term performance actually lives — corners, transitions, and penetrations done right.
- Final walkthrough. We go over the finished job with the homeowner before calling it done.
Why a Crew That Already Works Marietta Matters
A lot of siding problems in this part of Fairhaven aren't material failures — they're installation choices that didn't account for what the site actually experiences. A crew that's worked other homes in Marietta already knows which walls take the brunt of the wind-driven rain, how shaded lots need extra attention on drainage and finish choice to fight moss, and how salt exposure affects fastener and flashing decisions. That's not something you get from a general contractor doing their first job in the neighborhood — it's pattern recognition built from repeat work in this specific microclimate.
What to Ask Before Hiring for Board & Batten
- Will you install a drainage plane behind the siding, and how is it detailed at seams and openings?
- What fastener and flashing materials do you use, given the salt air here?
- How are field-cut edges sealed before installation?
- What's the batten spacing and fastening spec, and does it match manufacturer requirements?
- Do you check and document sheathing condition before installing new siding?
- What warranty applies to labor, separate from the manufacturer's material warranty?
Cost Factors for a Marietta Board & Batten Project
| Factor | Why it moves the number |
|---|---|
| Tear-off complexity | Multiple layers of old siding or hidden rot add labor and disposal time. |
| Sheathing repair | Rot found during tear-off has to be replaced before new siding goes on. |
| Wall height and access | Multi-story sections and tight side yards slow install pace and staging. |
| Trim and detail work | Corners, window surrounds, and transitions take more time on board and batten than plain lap. |
| Color and finish selection | ColorPlus factory finishes vary in cost by line and color; site-painted trim adds separate cost. |
We don't quote a number without seeing the home — every one of these factors changes with the actual property, and a broad "average" figure pulled off the internet won't reflect what your walls and sheathing actually need.
