Vinyl Membranes for Decks in Burien, WA
Burien's view decks sit high on the Puget Sound bluff, exposed to salt air and wind-driven rain off the water. A vinyl deck membrane is one continuous waterproof sheet with nothing for that weather to work into. North American made, from $2.75 USD/sq ft.
Exposed decks, salt air, driving rain
A west-facing deck on the Burien bluff takes weather most decks never see — wind off the Sound driving rain sideways into every joint.
Salt air off the Sound
Air coming off Puget Sound carries salt that corrodes fasteners and hardware over time. A membrane has no exposed fasteners in the walking surface at all.
Wind-driven rain
On an exposed bluff, rain doesn't just fall — it's driven sideways into seams, flashing, and wall junctions. Continuous heat-welded sheet and proper flashing detail is what actually stops it.
Mid-century housing stock
Burien's older neighborhoods are full of mid-century homes with original view decks and balconies, many now well past the life of their surfacing.
Decks over living space
Bluff-side homes often step down the slope, putting decks directly over rooms below. That makes the deck a roof, and it has to be waterproofed like one.
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.
Vinyl deck membranes across Burien and the Sound bluff
Burien's appeal is the view — homes stepping down the bluff toward Puget Sound with decks and balconies angled at the water and Vashon Island beyond. That position is also the problem. Those decks take salt air, sustained wind, and rain driven horizontally into every seam and wall junction, and many of them sit directly above living space on homes built into the slope.
A deck over an occupied room is a roof. It has to be waterproofed rather than surfaced. A vinyl deck membrane is a continuous heat-welded sheet, Intertek tested and code-compliant, so the rooms below stay dry.
What a vinyl deck membrane actually is
It's a single PVC sheet bonded to your prepared substrate, with every seam heat-welded so the deck becomes one continuous waterproof surface. Nothing penetrates it, and there are no joints for wind-driven water to work into.
Why exposure is the real test
Most deck surfaces cope with rain falling straight down. Far fewer cope with it being driven sideways for hours. With no gaps, no fastener holes, and heat-welded seams carried up the wall junctions, a membrane doesn't give that water a route in.

What is a vinyl membrane for a deck?
It's a single continuous PVC sheet bonded to your deck substrate, with all seams heat-welded so the surface becomes fully waterproof. Unlike boards or coatings, there are no gaps, joints, or fastener holes for water to get through.
Does salt air affect a vinyl deck membrane?
The membrane itself is PVC, so it doesn't corrode. It also has no exposed fasteners in the walking surface, which removes the parts most likely to fail near salt air.
Will it hold up to wind-driven rain on the bluff?
That's where a continuous membrane separates from board and coating systems. There are no seams or fastener holes for sideways rain to enter, and the membrane is carried up wall junctions with proper flashing so water can't get behind it.
Can it go over my existing Burien view deck?
Often, yes. If the structure is sound and the substrate can be prepared properly, the membrane bonds over it for a permanent waterproof finish. Contact us and we'll assess yours.
What do vinyl membranes for decks cost in Burien?
The membrane starts at $2.75 USD per square foot for material. Installed cost depends on deck size, substrate condition, and complexity. Size it with the cost calculator, or reach out for a quote.
