Waterproof Vinyl Decking, Built for Bellingham
Bellingham gets the wettest of the Pacific Northwest and sits closer to our factory than most BC cities do. Valordek is a continuous, fully sealed waterproof vinyl membrane, made just over the border in Surrey — barely 30 minutes north. From $2.75/sq ft.
Bay-town damp, all year
Tucked between the Salish Sea and the Cascades, Bellingham is one of the wetter spots in the Pacific Northwest. The cool, constant damp is what quietly works a deck apart here.
Heavy coastal rain
Bellingham catches consistent, year-round rain off the Salish Sea. Months of wet find every seam, board gap, and fastener hole in a deck. A continuous membrane leaves nowhere for water to enter.
Marine salt air
On the bay, salt-laden air corrodes fasteners and accelerates the breakdown of coatings and untreated wood. A continuous membrane with no exposed fasteners removes the parts salt air attacks first.
Moss and rot
Cool, damp, and shaded much of the year, Bellingham is prime moss country. Wood rots and composite greens over; vinyl doesn't absorb water, so it stays clean and the structure beneath stays sound.
Standing water
Flat decks and balconies pool water through the long wet season. Heat-welded seams and proper flashing keep that water sitting on a sealed surface instead of soaking in.
Two membranes. Built for two jobs.
Valordek bonds directly to your substrate and heat-welds into one continuous waterproof surface. No board gaps, no fasteners through the surface, nothing for water to find.
68mil Fuzzy-Back
The standard for residential balconies and decks over living space. Contact-adhered with heat-welded seams for a fully sealed, walkable waterproof surface.
60mil Smooth-Back
Built for rooftop and amenity decks. PVC flashing on open decks plus heat-welded seams. Class A & C fire rated and Intertek tested.
Practically local — just over the border
Here's Bellingham's advantage: Valordek is made and warehoused in Surrey, BC, barely 30 minutes north of the border. Bellingham is closer to our factory than most of the cities we serve in BC and Alberta. That means fast turnaround on material and samples, and the same membrane used on code-mandated balconies across the Lower Mainland, on Bellingham decks — from Fairhaven's historic homes to the hillside view properties of South Hill and Edgemoor and the student rentals around Western.
A deck or balcony over an occupied room is a roof — it has to be waterproofed, not just surfaced. Valordek is a continuous heat-welded membrane, Intertek tested and code-compliant, so the space below stays dry.
Why wood and coatings fail here first
Bellingham's cool, wet, shaded climate is hard on a deck: damp soaks into wood and feeds rot and moss, salt air off the bay corrodes fasteners, and paint-on coatings lift once water gets underneath. A continuous vinyl membrane doesn't absorb water, has no exposed fasteners to corrode, and no seams to fail — one sealed sheet built for exactly this climate.
Installing around the rain
Contact adhesive needs a dry substrate above 50°F, so installs are timed to dry windows rather than a fixed season. Bellingham's drier mid-summer is prime, and shoulder-season work is scheduled around clear spells.
Maintenance
Vinyl rinses clean with a hose and an occasional soft-brush wash — no sanding, no annual re-stain, and nothing for moss to grip, which is a real advantage through a long, damp Bellingham winter.

Where is Valordek made, and how fast can you supply Bellingham?
Valordek is made and warehoused in Surrey, BC — only about 30 minutes north of the border, closer than most cities we serve. That means quick turnaround on material and samples for Bellingham projects. Contact us to get started.
Is vinyl decking good for Bellingham's wet, coastal climate?
It's built for it. Valordek is a continuous, fully waterproof PVC membrane that doesn't absorb water, rot, or grow moss — and on the bay, it has no exposed fasteners for salt air to corrode, unlike a wood or coated deck.
What does vinyl decking cost in Bellingham?
The membrane starts at $2.75 per square foot for material. Total installed cost depends on deck size, substrate condition, and complexity. Size your project with the cost calculator, or reach out for a quote.
Will moss grow on it like my old deck?
No. Vinyl has no grain or open surface for moss to take hold and doesn't hold moisture — a real advantage in moss-prone Bellingham. A periodic rinse and soft-brush wash keeps it clean, with no sanding or re-staining.
Does it work for a balcony over a room?
Yes — a continuous heat-welded membrane fully seals a deck or balcony over living space so water can't reach the room below. The 60mil membrane is Intertek tested and fire rated for that use.
