Siding Installation in Lummi, WA — Alpine Exteriors

Out on the Lummi Peninsula, siding does not get the sheltered life it lives in town. Homes near Gooseberry Point and along Hale Passage face open salt water, and the southwesterly storms that funnel up the strait each winter drive rain sideways into wall assemblies. When Alpine Exteriors sides a home in Lummi, we treat it as marine-exposure work, because that is exactly what it is.

Salt, Wind, and Sideways Rain

Three things break siding down faster here than a few miles inland. First, wind-driven rain finds every unsealed penetration and unflashed window head. Second, salt-laden air corrodes cheap fasteners, leaving rust tracks bleeding through paint within a handful of seasons. Third, the hard freeze that can follow a wet southerly — cold outflow air spilling out of the Fraser Valley — turns trapped moisture into split boards and popped caulk joints.

The housing along the peninsula ranges from older beach cottages and manufactured homes to substantial newer waterfront construction, and each type fails differently. Cottages typically hide decades of patched cedar under layered paint; newer houses often wear builder-grade vinyl that the wind has been working loose one course at a time.

How We Build Walls for the Water's Edge

Our standard on exposed sites starts under the siding: a drainable weather-resistive barrier, properly lapped flashing at every opening, and stainless-steel or hot-dipped fasteners throughout. For the cladding itself, most Lummi homeowners land on one of these:

• Fiber cement lap siding — dimensionally stable in salt air, fire-resistant, and available in factory finishes that outlast site-applied paint.
• Premium vinyl rated for high wind, locked and fastened to resist the gusts that come off Hale Passage.
• Cedar, done correctly — back-primed, stainless-nailed, and detailed for owners who want the traditional look and accept the upkeep.
• Trim and soffit rebuilds, where rot almost always starts before the field of the wall shows a thing.

We photograph the sheathing before we cover it, so you know what condition your walls were actually in — and exactly what we fixed while they were open.

We also side homes across on Lummi Island, timing material runs around the Whatcom Chief ferry from Gooseberry Point. Island or peninsula, the plan is the same: schedule the wall tear-off inside a dry stretch, keep the house wrapped and weathertight every night, and never leave open sheathing exposed to a forecast that can turn in six hours out here.

Experience You Can Verify

Alpine Exteriors has worked northwest Washington's shoreline and farmland for 25 years, with more than 2,000 projects behind us from Ferndale to the county's outer peninsulas. We back our installations with a 25-year workmanship warranty, and we offer free on-site estimates — which matters on exposure-driven jobs like these, because no honest siding quote for a waterfront home can be written from a satellite photo. If your walls are chalking, cracking, or showing rust stains at the nail lines, have us walk the property before another storm season gets its turn at the problem.
