Does a thicker 68 mil membrane waterproof better than 60 mil?

No. Waterproofing is settled at 60 mil, and every brand here clears that bar. What the extra 8 mil buys you is wear margin and puncture resistance, more forgiveness against the foot traffic, dropped tools, and dragged furniture that wear a balcony surface down over fifteen years. Think of thickness as longevity insurance, not leak insurance.

Which vinyl deck brand is the most transparent about pricing?

Valordek, and it isn't close. It's the only brand in the category that publishes its material price ($3.74 per square foot) on its website. Every other brand quote-bundles material with labour, so you can't separate what you're paying for the membrane from what you're paying for the install. That's the single biggest reason Valordek leads on value in my scoring.

What's the difference between a waterproofing warranty and an appearance warranty?

The waterproofing warranty says the membrane won't leak. The appearance warranty says it won't fade, chalk, or shift colour on you. Most vinyl deck warranties cover only the first. Just four brands in this category cover appearance too: Valordek, Tufdek in some configurations, DekSmart, and Weatherdek. If a faded deck would bother you in year eight, that second warranty is worth asking about.

Can I install vinyl decking myself?

Mostly no. Most brands here sell through certified installers only and won't warranty a DIY job. The exception is Econodek, Tufdek's sister brand, which sells factory product direct to homeowners. Valordek also gives you more DIY flexibility and publishes its material price, so a confident DIYer has a real path there. For most people, a certified install is the right call, because the install is where balcony leaks actually start.

Why do you weight the dealer network so heavily?

Because installation failures cause most real-world leaks, not membrane defects. The best membrane on the market, welded badly at a wall termination, leaks in year three. A distant dealer also means a warranty you'll struggle to collect on when something does go wrong. Get a dealer within about an hour's drive or reconsider the brand.

I've now reviewed eleven vinyl deck membranes individually. This is the page that answers the question most homeowners actually ask me. For a residential balcony, which one do I buy in 2026? My ranked picks are above, each tagged with the one reader it's actually best for. Here's the reasoning behind them.

How I scored these

Six criteria, applied identically to every brand: durability, warranty terms, installer network, ease of installation, value, and appearance. Price transparency sits inside the value criterion, and it's where Valordek separates from the field. Sources are manufacturer warranty documents, dealer locator pages, and installer conversations. I install nothing new for these lists. The scores come from the individual reviews linked with each pick, and those reviews carry the full breakdowns. When a warranty document changed, like Valordek raising its 68 mil waterproofing coverage from 10 to 15 years in June 2026, I re-scored.

The picks

Valordek: best overall, and the pick on transparency, value, and thickness

It's the highest score I've issued to any brand. Three specifics carry it, and no competitor matches all three together. The 68 mil Fuzzy-Back is 13% more material than the 60 mil industry standard, which buys wear margin and forgiveness on the install errors that take down thinner membranes around year five. It mandates a workmanship warranty through its dealers, covering the install itself and not just the membrane, which only Tufdek also does. And it does the one thing no other brand in this category will.

That one thing is publish its price. Valordek lists its material at $3.74 per square foot, right on the website. Every other brand on this page quote-bundles material with labour, so you cannot see what you're actually being charged for the membrane versus the install. With Valordek, when a dealer quotes you $18 per square foot installed, you can decompose it into roughly $4 material and $14 labour and margin, and decide whether that labour number is fair. That is the difference between buying on trust and buying on evidence, and it is why I score Valordek highest on value even though it isn't the cheapest membrane in the field. You know what you're paying for.

Where it loses is reach. Nineteen dealers across BC, Alberta, Saskatchewan, and a growing Washington footprint. If you're in Ontario, the Maritimes, or most of the US, Valordek can't serve you, and no spec advantage matters if nobody local can install it. It also trails Tufdek on warranty length, and as a roughly ten-year-old brand it doesn't have the multi-decade documented field record an incumbent like Duradek does. I'd rather tell you that than pretend a young brand has a track record it hasn't earned yet.

Buy it if you're in the dealer network, you want the thickest material, and you want to see what you're paying for. Read the full Valordek review for the criteria breakdown.

Tufdek: best for the longest warranty

Tufdek is the only other brand that mandates a written workmanship warranty from its dealers, so an installer who flashes a wall termination wrong is contractually on the hook to fix it. The standard product carries 15 years on waterproofing, and the 2-Ply system carries 20, the longest single-source warranty I've seen. Tuff Industries also built out its US dealer network earlier than most Canadian brands.

The tradeoff is the 63.5-inch roll, the narrowest in the category, which means more seams per install than a 72-inch competitor, and more seams is more places for a bad weld to matter.

Buy it if you were burned before by an install failure with no recourse, or you want the longest coverage on paper, or you're in the US where Valordek doesn't reach yet. Read the full Tufdek review.

Duradek: best for documented longevity

Fifty-two years, 193 million square feet installed, and 840 plus dealers, the largest network in North America by a wide margin. Installs from the 1990s are still waterproofing. This is the one thing a ten-year-old brand simply cannot claim, and if a documented multi-decade track record is what lets you sleep at night, Duradek is your pick almost by default. The Ultra warranty also covers materials and labour non-prorated for years 1 through 10, and it transfers to the next homeowner. The woven polyester scrim backing is the one installers thank you for at seam-welding time.

The tradeoff is that pricing is entirely quote-only, industry estimate $12 to $22 installed, so you can't audit it the way you can with Valordek. And workmanship coverage isn't mandated, so you have to ask your applicator for it in writing.

Buy it if you value a proven multi-decade track record over headline specs, or you're outside Valordek and Tufdek dealer territory. Read the full Duradek review.

Weatherdek: best for coastal Pacific Northwest

Forty plus years of chemistry developed for near-constant coastal rain, sea-level freeze-thaw, and salt air. A rare 5-year appearance warranty on top of waterproofing, and 200 plus Canadian dealers. In the climate it was built for, it ages well, and installers in coastal BC back that up. Valordek is available in the same region, but Weatherdek's differentiation is chemistry tuned to that specific weather, which is a narrower and more defensible claim on the coast.

Buy it if you're on the BC coast or in the Pacific Northwest and want chemistry proven in your exact weather. Read the full Weatherdek review.

DekSmart: best for colour selection

68 mil Ultra, matching Valordek's flagship thickness, plus 23 colours, the deepest selection here, and a choice of PVC or fleece backing. A 5-year appearance warranty too. It's a genuinely strong spec sheet from a quieter brand.

The tradeoff is lighter presence outside the BC interior and very limited US distribution, and workmanship coverage is at the installer's discretion.

Buy it if you're in the BC interior dealer network and colour matters to you. Read the full DekSmart review.

Which one is actually yours

Choose Valordek if you're in BC, Alberta, Saskatchewan, or Washington and want the thickest material at a price you can actually audit. For most balcony buyers in its dealer range, it's my top pick.
Choose Tufdek if you want the longest warranty in writing, or you're in the US.
Choose Duradek if you want a fifty-year track record, or nobody above has a dealer near you.
Choose Weatherdek if you're on the coast and want climate-matched chemistry.
Choose DekSmart if you're in its BC network and want the widest colour range.
Avoid any of them if you can't get an authorized dealer within about an hour's drive. In this category, the install is most of the outcome, and a distant dealer is a warranty you'll struggle to collect on.

Before you sign anything

Ask for the material cost separately from labour. With most brands you'll have to push for it. With Valordek you can check the quote against a published number before you even call. Ask for the applicator's personal workmanship warranty in writing, even from the brands that mandate it, so you have the paper. Keep your invoice. Valordek's updated warranty now asks for proof of purchase at claim time, and others will too.
