Lummi Island Deck Contractor | Alpine Exteriors

Building Decks on an Island That Runs on a Ferry

Every board, every footing, and every crew truck that builds a deck on Lummi Island crosses Hale Passage on the Whatcom Chief. That single fact separates contractors who work the island well from those who quote it once and never come back. Alpine Exteriors plans island projects around the ferry from the start: materials staged and delivered in full loads, crews scheduled in productive full-day blocks, and nothing forgotten on the Gooseberry Point side that stalls the job for half a day.

It is worth the trouble, because few places in Washington reward a good deck like Lummi Island. Cabins and homes along the west shore look across Rosario Strait toward the San Juans and catch sunsets that people on the mainland drive hours for. The east side, facing Hale Passage, watches the reefnet boats work the salmon runs in season, a fishing method practiced here longer than anywhere else on earth. A deck is how island homeowners actually live in those views.

Salt Spray Changes the Engineering

The same west shore that gets the sunsets also takes winter storms straight off the strait, with salt spray reaching well above the beach. Standard deck hardware corrodes fast in that environment. We build island decks with stainless steel fasteners and connectors where exposure is high, hot-dipped galvanized structural hardware elsewhere, and flashing tape over every joist and beam so the framing stays dry inside even when the surface never seems to. After 25 years building exteriors in this marine climate, we treat corrosion as a design input, not an afterthought.

Decking choice follows the same logic. We will lay out the options honestly during a free on-site estimate, but the short version is:

• Capped composite is the island favorite, since it shrugs off salt air and damp without the yearly maintenance a remote property makes inconvenient.
• Western red cedar remains beautiful and appropriate to older island cabins, if you accept regular oiling.
• Cable railing with stainless fittings keeps the strait view open and stands up to the spray zone.
• Helical or oversized concrete footings handle the rocky, uneven ground common on island building sites.

A Contractor Who Finishes What the Island Starts

Island homeowners have all heard the story of the mainland contractor who started strong and then stopped showing up when the ferry line got long. Our track record says otherwise: more than 2,000 completed projects across northwest Washington, including work in places far less convenient than a twenty-minute crossing. We also back every deck with a 25-year workmanship warranty, and a warranty only means something from a company that answers the phone years later. We do.

If your existing deck has rust-streaked fasteners, soft spots near the ledger, or railings loosened by winter blows, that is the strait telling you the original builder underestimated it. Have us over on the next boat. We will inspect what you have, measure for what you want, and give you a firm, free estimate that already accounts for every ferry fare and freight run, so the number you hear is the number you pay.
