Waterproof Vinyl Decking, Built for Tacoma
Tacoma's older homes and South Sound weather are a tough combination — century-old porches and decks soaking through long Pacific Northwest winters. Valordek is a continuous, fully sealed waterproof vinyl membrane, North American made. From $2.75/sq ft.
Old decks, relentless damp
Tacoma pairs one of the region's older housing stocks with the full South Sound soak. A lot of these decks have been fighting moisture for decades — and losing.
South Sound rain
Tacoma takes the same long Pacific Northwest wet season as the rest of Puget Sound — months of steady rain that find every seam and fastener hole. A continuous membrane simply doesn't have any.
Aging housing stock
Tacoma is full of early-1900s homes with original porches, balconies, and stair landings. A continuous membrane is a clean, permanent waterproof reset over a tired old deck — provided the structure is sound underneath.
Moss and rot
Constant damp grows moss on timber and composite and rots the framing beneath. Vinyl doesn't absorb water, so the surface and the structure under it stay dry and clean.
Standing water
Flat porches and low-slope decks pool water through the wet season. Heat-welded seams and proper flashing keep that water on a sealed surface instead of soaking into old wood.
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.
Serving Tacoma and the South Sound
Tacoma is a city of front porches and view decks — the historic homes of the North End and Stadium District, the bungalows of Hilltop and the East Side, and waterfront properties looking out over Commencement Bay toward Mount Rainier. Newer townhomes and condos are filling in around downtown and along the waterfront too. Across all of it, the job is the same: keep the South Sound rain out of decks and the rooms beneath them.
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. That matters on Tacoma's many older homes, where decades of patch-and-coat have usually run their course.
A practical reset for an old deck
Many Tacoma decks sit on aging substrates that have been re-coated and re-flashed for years. Provided the structure is sound, Valordek bonds over the prepared surface and gives a century-old porch or balcony a single, permanent waterproof finish — no more chasing leaks every winter.
Why wood and coatings fail here first
Constant Puget Sound damp soaks into wood and feeds rot and moss, while paint-on coatings blister once water gets underneath. A continuous vinyl membrane doesn't absorb water and has no gaps, fasteners, or seams to fail — one sealed sheet that sheds the rain off old and new decks alike.
North American made, shipped from nearby
Valordek is manufactured in Surrey, BC, north of the border, and ships into Washington regularly — so Tacoma projects stay close to the source for material, samples, and support.

Can it go over my older Tacoma deck or porch?
Often, yes. Provided the structure is sound and the substrate can be properly prepared, Valordek bonds over it for a clean, permanent waterproof finish — a practical fix for the many century-old porches and decks around Tacoma. Contact us and we'll assess yours.
Is vinyl decking good for the wet South Sound climate?
It's built for it. Valordek is a continuous, fully waterproof PVC membrane — no board gaps, fastener holes, or open seams for the rain to get through, and it doesn't absorb water, rot, or grow moss the way wood and composite do.
What does vinyl decking cost in Tacoma?
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.
Does it work for a balcony over a room?
Yes — that's a core use. 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.
