Board and batten siding — wide vertical panels with narrow battens covering each seam — has become one of the most requested looks in Bellingham, Ferndale, Lynden, Blaine, Birch Bay, Sudden Valley and out on the islands. Homeowners like the clean modern-farmhouse lines and the way it reads as a distinct accent against lap siding or stone. What it costs to install correctly in this part of Washington depends less on the style itself and more on the material you choose, the condition of the wall behind it, and how the assembly is built to shed the rain this county gets for most of the year. Below is a realistic breakdown so you can budget with your eyes open before you start collecting quotes.
Board and batten in Whatcom County typically lands in a wide range because the category spans everything from engineered wood panel systems to real cedar boards installed one at a time with a rainscreen gap behind them. Fiber cement board and batten (LP-style or Hardie-style vertical panel systems) generally installs at the lower-to-middle end of that range once you include trim and flashing. True cedar board and batten, hand-fitted with solid battens and back-primed on every cut, sits at the top of the range because of both material cost and the labor hours involved. A full tear-off of failed old siding, extensive rotten sheathing, or a house with a lot of dormers, bump-outs and window trim will push any material choice toward the higher end.
| Cost Factor | Low End | High End |
|---|---|---|
| Fiber cement board and batten, straightforward one-story wall | Lower | Mid |
| Engineered wood (treated composite) board and batten | Lower-mid | Mid |
| Real cedar board and batten, hand-installed | Mid-high | Highest |
| Tear-off and disposal of existing siding | Adds a modest amount | Adds significantly if rot repair follows |
| Sheathing/framing repair behind old siding | Minor if isolated | Substantial if widespread rot |
| Rainscreen/drainage gap assembly | Small add over face-nailed install | Larger add on complex elevations |
| House complexity (dormers, gables, trim detail) | Minimal add on simple walls | Meaningful add on cut-up facades |
| Access (steep Sudden Valley lots, island ferry logistics) | Little to no effect | Noticeable add for staging and freight |
Because this is a wide range across a whole county, the only way to get a number you can actually plan around is a walk-through quote against your specific house, elevations and existing wall condition. Alpine Exteriors prices board and batten jobs after that walk-through rather than off a phone estimate, precisely because two houses of the same square footage can land at very different numbers depending on what's under the old siding.
A handful of site-specific conditions consistently move board and batten pricing up or down in this part of Washington:
A board and batten quote worth comparing to others should spell out, in writing, at minimum:
Alpine Exteriors writes each of these into the proposal before work starts, because a bid that only lists a total dollar figure gives you no way to know what happens if the crew finds rotten sheathing on day two.
When you're holding two or three bids side by side, resist the urge to rank them by bottom-line number alone. Start by confirming each bid describes the same material and the same assembly — a face-nailed budget install and a rainscreen assembly with back-primed cedar are not the same job, even if both get called "board and batten." Ask each contractor how they'll handle sheathing repair if it's discovered mid-project, and get that answer in writing rather than as a verbal assurance. Confirm each contractor's Washington contractor license is active and ask what their labor warranty actually covers versus what's simply the manufacturer's material warranty passed along. A noticeably low bid is worth a direct question about what's been left out — often it's the drainage gap, the trim package, or the disposal cost that shows up later as a change order. Alpine Exteriors holds Washington contractor license ALPINI751OW and is glad to have that verified independently before any contract is signed.
Many siding contractors, Alpine Exteriors included, can point homeowners toward third-party financing options that break a full re-siding project into monthly payments rather than requiring the full amount up front — ask about this during your consultation if it matters to your budget. On the insurance side, siding replacement is sometimes triggered or partly covered by a homeowner's policy when the failure is tied to a covered event such as a wind or water intrusion claim rather than routine wear, so it's worth a call to your insurer before assuming a project is entirely out of pocket. Keep in mind that ordinary moss growth, sun fading, or age-related wood rot from years of Whatcom County rain is typically treated as maintenance rather than a covered loss, so don't count on insurance to offset a simple upgrade or cosmetic refresh.
It can be, but only when it's detailed correctly. Because board and batten relies on vertical seams and butt joints at trim, the installation needs careful flashing and, ideally, a drainage gap behind the boards so that any water that gets past the face has somewhere to go rather than sitting against the sheathing. On elevations that take wind-driven rain off Bellingham Bay or the Strait, that detailing matters more than the material choice itself.
Timelines vary with house size, weather windows, and how much repair work turns up once the old siding is off. A single-story home with sound sheathing moves faster than a two-story house needing rot repair and new trim throughout. Because Whatcom County has a genuine wet season, scheduling around dry stretches also affects how quickly a project can move from tear-off to finished paint.
In some cases, yes, but it's rarely the right call here. Covering old siding traps whatever moisture or rot is already present, and in a climate with this much sustained rain, that's a real long-term risk rather than a minor shortcut. A tear-off lets the crew inspect and repair the sheathing and water-resistive barrier before anything new goes up, which is the more defensible approach for a project meant to last.
It can, in a good way. Re-siding is often the most practical time to add exterior rigid insulation and improve air-sealing at the wall assembly, both of which are addressed under the Washington State Energy Code. If energy performance matters to you, ask your contractor whether the proposed assembly meets or exceeds current code requirements for continuous insulation, rather than assuming any new siding automatically improves efficiency.
Board and batten siding can be a durable, good-looking choice anywhere from Bellingham to Blaine to the islands, but only when the assembly underneath is built for this region's rain, moss and freeze-thaw conditions rather than for a drier climate. If you're weighing board and batten against other siding options, or you already know it's the look you want and need a real number for your house, Alpine Exteriors can walk your property, check the condition of the existing wall, and put together a written quote that spells out material, assembly and warranty terms in plain language.
