Waterproof Vinyl Decking, Built for Vancouver
Vancouver decks live under eight months of rain. The enemy here isn't cold — it's relentless moisture finding every seam and rotting the structure below. Valordek is a continuous, fully sealed waterproof vinyl membrane. Made just up the road in Surrey by 25-year waterproofing pros.
On the coast, water is the whole problem
Vancouver doesn't punish a deck with cold — it punishes it with water, constantly, for most of the year. That's a different fight, and it's the one vinyl membrane was built for.
Eight months of rain
Vancouver sees roughly 1,200 mm of rain across more than 160 wet days a year. Any deck system with seams, board gaps, or fastener holes will eventually let that water through. A continuous membrane gives it nowhere to go.
Rot, moss and mould
Constant damp is what rots wood joists and grows moss on composite and timber decks. Vinyl doesn't absorb water, so the surface — and the structure under it — stays dry and clean.
The leaky-condo legacy
Vancouver learned the cost of bad balcony waterproofing the hard way. Decks over living space must be sealed to code, not just surfaced — a continuous heat-welded membrane is exactly that.
Standing water
Flat balconies and low-slope decks pool water through the wet season. Heat-welded seams and proper flashing mean pooled water sits on top of a sealed surface instead of seeping into it.
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 meltwater 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.
Serving Vancouver and the Lower Mainland
Valordek is made in Surrey, so Vancouver is home turf — product is stocked locally and ships across the Lower Mainland same-week. From heritage homes in Kitsilano and Mount Pleasant to East Van infills and the wall of glass towers in Yaletown, Coal Harbour, and along the waterfront, the city is full of decks and balconies built over living space. Every one needs to keep eight months of rain out of the rooms below.
Vancouver takes that seriously for good reason. The National Building Code treats any deck or balcony over occupied space as a roof — it has to be waterproofed to CGSB 37.54 standards, not just surfaced. Valordek's membranes carry CCMC and Intertek certification confirming they meet code 37.54.95, so a balcony over a suite, garage, or unit is sealed properly.
Rooftop patios and condo balconies
Vancouver's density means a huge share of outdoor space is elevated — rooftop terraces downtown, shared amenity decks on mid-rises, and private balconies on thousands of condos and townhomes. The 60mil Smooth-Back membrane is built for these: Class A & C fire rated, with PVC flashing and heat-welded seams that stay watertight through the wettest winter.
Why wood and coatings fail here first
A timber or composite deck in Vancouver is in a constant fight with moisture. Water sits in board gaps and fastener holes, soaks into the wood, and feeds rot and moss; paint-on coatings blister and peel once water gets underneath. A continuous heat-welded vinyl membrane doesn't absorb water and has no gaps, fasteners, or seams to fail — it's one sealed sheet that sheds the rain.
Installing around the rain
Contact adhesive needs a dry substrate above 10°C, so the trick in Vancouver isn't temperature, it's timing the dry windows. The long, dry mid-summer stretch is prime, and shoulder-season installs are scheduled around clear spells. Your local installer can read the forecast and book accordingly.
Maintenance
Vinyl rinses clean with a hose and the occasional soft-brush wash — no sanding, no annual re-stain, and nothing for moss to grip. That's a real difference over a Vancouver winter, when wood and composite need constant attention to stay ahead of the damp.

Is vinyl decking good for Vancouver's wet climate?
It's built for it. Valordek is a continuous, fully waterproof PVC membrane — no board gaps, fastener holes, or open seams for rain to get through. Unlike wood or composite it doesn't absorb water, rot, or grow moss, which is exactly the problem Vancouver decks face.
Does it meet building code for balconies over living space?
Yes. Decks and balconies over occupied space must be waterproofed to CGSB 37.54. Valordek's membranes carry CCMC and Intertek certification confirming they meet code 37.54.95 — the standard that matters after Vancouver's leaky-condo history.
What does vinyl decking cost in Vancouver?
The membrane starts at $3.74 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.
Can it be installed during the rainy season?
Installation needs a dry substrate above 10°C, so the job is scheduled around dry windows rather than a fixed season. Mid-summer is prime; shoulder-season installs are booked around clear spells. Being Surrey-based, we can move quickly when the forecast opens up.
Will moss grow on it like my old deck?
No. Vinyl has no grain or open surface for moss to take hold, and it doesn't absorb moisture. A periodic rinse and soft-brush wash keeps it clean — no sanding or re-staining through the wet season.
