What's the actual difference between board and batten and regular lap siding installation?

Lap siding overlaps horizontal boards downward to shed water, while board and batten uses vertical boards or panels with a second layer of narrow strips, called battens, covering the seams. Board and batten has more vertical seams and fastener penetrations than lap siding, so the water-resistive barrier, flashing, and fastening details underneath matter even more to get right.

What should I ask a contractor before they install board and batten on my Custer property?

Ask them to describe the drainage plane or rain screen gap they'll build behind the siding, what fastener type they'll use given the coastal exposure, and how they'll handle flashing at windows and trim. A contractor who can answer specifically, rather than in general terms, is more likely to build the wall correctly the first time.

Why doesn't your company install board and batten in vinyl or wood?

We install exclusively in James Hardie fiber cement because of how it holds up against the moisture, salt air, and moss growth common in this climate compared to wood, which needs ongoing repainting and rot monitoring, or vinyl, which can trap moisture and expand and contract more with temperature swings. It's a standard we apply to every style we install, not just board and batten.

Which James Hardie product do you use for board and batten siding here?

We use James Hardie's vertical panel siding paired with matching trim boards as battens, built from their HZ10 product line, which is engineered specifically for wetter, moderate coastal climates like Whatcom County rather than hotter, drier regions. The boards arrive with a factory-applied ColorPlus finish rather than needing paint on site.

Does Custer's location near the water actually change how board and batten should be built or maintained?

Yes — homes with more direct salt air exposure need corrosion-resistant fastener specs and benefit from periodic rinsing to clear salt residue, and shaded or damp walls need batten spacing and drainage detailing that accounts for heavier moss growth. A wall built the same way regardless of its exposure on the property is more likely to show problems unevenly over time.

Board & Batten Siding in Custer: A Style That Has to Earn Its Keep

Board and batten has a strong, clean vertical line that works well on the mix of farmhouse-style homes, rural properties, and newer builds you find around Custer. It's a look a lot of homeowners in this part of Whatcom County ask for by name. But board and batten isn't just an aesthetic choice — the way it's built directly affects how well a house holds up against the weather this stretch of coastline throws at it. A batten pattern that looks identical from the street can perform completely differently depending on what's underneath it, what it's fastened with, and what material the boards themselves are made of.

This page is specifically about installing board and batten siding on homes in and around Custer, where salt-laden air off the water, long stretches of driving rain, and a moss season that can run most of the year all put real demands on an exterior. We'll walk through what that climate does to vertical siding, what a correct board and batten installation actually involves, and why we install this style only in James Hardie fiber cement.

What Custer's Climate Does to Vertical Board Siding

Custer sits close enough to the water that homes here deal with airborne salt on a regular basis, on top of the rain and moisture load that's just part of living in Whatcom County. Board and batten siding is more exposed to some of these effects than standard horizontal lap siding, for a few reasons specific to its design.

Salt Air and Fasteners

Board and batten relies on a second layer of fasteners running through the battens themselves, on top of whatever holds the base boards or panels in place. Every one of those fastener penetrations is a place where corrosion can start if the wrong hardware is used. In a coastal-influenced area like Custer, standard fasteners can corrode faster than they would further inland, leading to rust streaking, loosened battens, and eventually water intrusion at the fastener holes.

Driving Rain and Vertical Seams

Wind-driven rain off the water doesn't just fall straight down — it gets pushed sideways into vertical seams and batten joints. Board and batten has more vertical seam length than lap siding of the same square footage, which means more opportunities for wind-driven moisture to find a way behind the cladding if the water-resistive barrier, flashing, and gaps aren't detailed correctly.

Moss and Algae Growth

Custer's long damp season, shaded lots, and moisture-holding tree cover create ideal conditions for moss and algae to take hold on exterior surfaces. Vertical siding with battens creates horizontal ledges and shadow lines at the top of each batten where organic growth and debris like to collect if the material and finish aren't resistant to it.

None of this means board and batten is a bad choice for Custer — it means the material and the installation details matter more here than they would in a milder, drier climate.

Board and Batten Is a System, Not Just a Pattern

A correct board and batten installation is really several layers working together, not just boards nailed to the wall with strips over the seams. On every project we build in Custer, the assembly includes:

A water-resistive barrier installed and lapped correctly behind the siding
A rain screen gap that lets any moisture that does get behind the cladding drain and dry out instead of sitting against the wall sheathing
Corrosion-resistant fasteners rated for coastal exposure, sized and spaced to the manufacturer's engineering specifications
Flashing at every horizontal transition — window and door heads, trim boards, and the base of the wall
A batten layout and reveal spacing planned before the first board goes up, not adjusted on the fly

Skip any one of these and the siding may look right for a few years while quietly trapping moisture behind it. That's a slower, harder-to-spot failure than a leak, and it's exactly the kind of shortcut that shows up as soft sheathing or hidden rot when a homeowner finally has a wall opened up for an unrelated reason.

Why We Only Install Board and Batten in James Hardie Fiber Cement

Board and batten can be built in several different materials, and each one behaves differently once it's exposed to a climate like Custer's. We standardized on James Hardie fiber cement for this style — and every other style we install — because of how it holds up specifically against salt air, sustained rain, and moss.

Factor	Wood Board & Batten	Vinyl Vertical Panel	James Hardie Fiber Cement
Moisture behavior	Absorbs water; swells, cups, and rots at seams and fastener points	Doesn't absorb, but can trap moisture behind it and warp with heat/cold cycling	Engineered to resist moisture absorption without warping
Salt air / corrosion exposure	Fasteners and any metal trim corrode faster; wood itself has no corrosion resistance issue but rots	Panel is inert, but fastening and expansion issues remain in coastal wind	Non-combustible, dimensionally stable material paired with corrosion-resistant fastener specs
Moss / algae resistance	Bare or painted wood is a food source for organic growth once damp	Smooth surface resists growth better but seams and J-channels still collect debris	ColorPlus factory finish resists moss and mildew better than field-applied paint
Maintenance burden	Repainting and caulking every few years; ongoing rot inspection	Low maintenance but can crack or fade; hard to patch invisibly	Occasional washing; finish is baked on at the factory, not brushed on-site
Long-term warranty	No manufacturer warranty on the material itself	Limited warranty, often prorated	Long, transferable manufacturer warranty on both substrate and finish

We're not suggesting wood or vinyl board and batten can't be installed competently — plenty of it is. Our position is narrower: given what we see this climate do to siding over time, and given that James Hardie's HZ10 product line is engineered specifically for wet, moderate coastal climates like this one, it's the material we're willing to put our name behind for board and batten work in Custer.

Our Process for a Custer Board & Batten Project

1. On-Site Assessment

We look at the home's exposure — how close it sits to open water or wind corridors, how much shade and moisture the walls hold onto, and the condition of the existing sheathing and water-resistive barrier where it's accessible.

2. Material and Layout Planning

We plan board width, batten spacing, and reveal before ordering material, so the pattern lines up cleanly around windows, corners, and gable ends instead of getting fudged at the end of a run.

3. Tear-Off and Wall Prep

Old siding comes off, the sheathing is inspected for hidden moisture damage, and any repairs are made before a new water-resistive barrier goes on.

4. Rain Screen and Flashing Installation

We install the drainage gap and all flashing details — window heads, trim intersections, and the base of the wall — before a single course of siding goes up.

5. Board and Batten Installation

Vertical boards or panels go up first, fastened per James Hardie's engineering specifications, followed by the battens over each seam using corrosion-resistant fasteners suited to coastal exposure.

6. Final Inspection

We walk the finished wall checking fastener lines, caulk joints, flashing laps, and reveal consistency before calling the job complete.

Choosing Reveal, Batten Spacing, and Color for a Custer Home

Board and batten gives you more design decisions than standard lap siding, and getting them right matters both for looks and performance:

Board and Batten Spacing

Wider spacing reads as more modern and farmhouse; tighter spacing reads more traditional. Spacing also affects how much of the base board is visible and how much shadow line the battens cast — which matters for how moss and grime show up on the wall over time.

Color and ColorPlus Finish

James Hardie's factory-applied ColorPlus finish is baked on before the boards ever reach the job site, which gives more consistent, longer-lasting color than field-painted wood board and batten — a real advantage given how much moisture and UV exposure this area's siding takes on over a year.

Trim and Corner Details

Outside corners, window casing, and fascia trim all need to be planned as part of the same system, not treated as an afterthought once the field siding is up.

Living With Board and Batten in a Salt Air, High-Moss Climate

Even a correctly installed board and batten wall needs some basic upkeep in Custer's climate:

Rinse the exterior periodically to clear salt residue and organic buildup before it sets in, especially on north- and shade-facing walls
Keep gutters and downspouts clear so runoff doesn't sheet down the siding face
Trim back vegetation and tree cover that keeps walls damp and shaded for extended periods
Have caulking and fastener heads checked periodically, since these are the first points where wear shows up
Address any soft spots, discoloration, or lifted battens promptly rather than waiting

This is meaningfully less upkeep than repainting a wood board and batten exterior every few years, but it isn't zero-maintenance — no exterior siding in this climate is.

What a Correct Board & Batten Installation Should Include

If you're comparing quotes for board and batten siding in Custer, here's what should be part of any proposal, regardless of who does the work:

A specified water-resistive barrier and how it will be lapped and sealed
A rain screen or drainage gap behind the siding, not direct-to-sheathing installation
Fastener type and spacing called out, matched to coastal exposure conditions
Flashing details at every window, door, and horizontal trim transition
A planned batten layout, not "we'll figure out spacing as we go"
Manufacturer installation instructions being followed, not just general carpentry judgment

If a quote doesn't address these points, it's worth asking directly — a straight answer about drainage planes and fastening specs tells you a lot about how a crew will actually build the wall.

Why a Crew That Already Works in Custer Is Worth Something

Board and batten installed to a generic spec sheet doesn't automatically account for the specific mix of salt exposure, rainfall pattern, and moss pressure a given property in Custer deals with. A crew that regularly works homes in this part of Whatcom County has already seen how these conditions play out over years, not just at the one-year mark — which shows up in decisions like fastener choice, rain screen detailing, and how tight to run batten spacing on a shaded, damp wall versus a more exposed one.
