Out on the Lummi Peninsula, weather arrives sideways. Southerlies push up Hale Passage, salt spray carries off Bellingham Bay, and a west-facing window near Gooseberry Point or along Lummi Shore Road takes more abuse in one winter than an inland window sees in five. Alpine Exteriors has spent 25 years replacing windows in exactly these conditions across Whatcom County, and we build every Lummi project around one question: which direction does this wall face, and what does the water throw at it?
What Salt Wind and Nine Wet Months Do to Lummi Windows
A lot of the housing out here dates to the 1960s through the 1980s — beach cabins that grew into year-round homes, ramblers on acreage off Haxton Way, and waterfront places at Sandy Point and Neptune Beach. Many still carry their original single-pane aluminum sliders. Aluminum conducts cold straight through the frame, so on a damp January morning the interior glass sweats, the sill stays wet, and over the years that moisture rots the framing below. Salt accelerates everything: it pits hardware, corrodes balances, and chews through cheap exterior cladding.
We see the same failure pattern again and again on the peninsula — fogged double-pane units that lost their seal to constant pressure swings, crank operators seized by corrosion, and sashes that no longer latch tight against a southeast blow. If you can hear the wind whistle at the meeting rail, the window is done working for you.
