Shaw Island Siding Contractor | San Juan Islands

Siding Work on Shaw, Planned Around the Ferry

Any contractor can promise good siding. On Shaw Island, the promise that matters is logistical: every board, roll of weather barrier, box of fasteners and crew member arrives by ferry through Shaw Landing, and a forgotten item is not a quick supply run, it is a lost day. Alpine Exteriors has worked across the San Juans long enough to plan island projects the way they have to be planned: complete material takeoffs, staged deliveries, and crews scheduled around the sailing timetable so your project moves forward instead of waiting on a boat.

The island itself is hard on cladding in a way that has nothing to do with rainfall totals. Shaw sits in the rainshadow, so it gets less rain than the mainland, but it trades that for relentless salt exposure off Harney Channel and Upright Channel, wind funneling between the islands, and intense southwest sun in summer. Siding here fails by corrosion, UV and wind-driven salt mist more often than by simple soaking.

Materials That Earn Their Ferry Ticket

Because everything shipped to Shaw costs more to bring back, we specify materials that will not need a second trip for decades.

• Stainless steel fasteners exclusively, since galvanized coatings surrender early within reach of salt air
• Factory-finished fiber cement or knot-free cedar, both proven on exposed island shorelines
• A vented rainscreen assembly that lets salt-damp walls dry from behind, doubling the life of any finish
• Marine-grade flashings at every window, door and deck ledger, bent on site to fit each opening

Many Shaw homes are cabins and family places passed down through generations, and their owners usually want the island vernacular kept intact: cedar shingle sidewalls weathering to silver, simple board trim, nothing flashy. We are glad to build exactly that, just with a modern water management system hidden underneath so the next generation inherits walls, not rot.

One Mobilization, Done Right

Island work rewards doing everything while the crew is there, so we commonly fold in the adjacent repairs that make sense at the same time: rebuilding a rotten window sill, replacing failed trim, re-flashing a deck connection. It all gets captured during a free on-site estimate, where we walk the property, measure every elevation and leave you a complete written scope, ferry logistics included, before you commit to anything.

Alpine Exteriors has spent 25 years building in northwest Washington, with more than 2,000 projects completed from the mainland to the islands, and we back Shaw work with the same 25-year workmanship warranty we offer everywhere else. Distance does not dilute the guarantee: if something we installed fails, we get on the ferry and fix it. That is the arrangement island homeowners deserve, and the one we have always honored.
