If you’ve looked at upgrading your balcony or deck, you’ve probably come across vinyl decking and maybe noticed it isn’t the cheapest option out there. That’s usually the moment people ask: “So what should this actually cost?”
The honest answer? It depends, but not as much as you might think.
For most projects, vinyl decking installations tend to fall into a fairly consistent range. In our experience, about 80% of jobs land somewhere between $15 and $25 per square foot, fully installed. That typically includes the membrane itself, adhesives, and finishing details like drip edges. Repairs to the underlying structure, if needed, are separate.
To put that into perspective, a simple 100-square-foot balcony might come in around $1,500 to $2,500. Larger spaces like rooftop patios can run into the thousands, although the price per square foot often drops a bit as the size increases.
So why the range?
Unlike traditional decking boards, vinyl membranes are part of a waterproofing system, not just a surface. Leading products like Duradek (widely considered the market leader in vinyl decking) are designed to create a fully sealed, long-lasting barrier against moisture. Installation isn’t a simple roll-out job either. It must be done by trained applicators using heat-welded seams, a precise and labour-intensive process. That added craftsmanship is a big part of the cost, but it’s also what makes the system so reliable over time.
A few things can nudge the price up or down:
- What’s underneath matters. If the plywood or structure below has rot or water damage, that needs to be fixed first. Sometimes it’s minor; sometimes it’s more involved.
- Design complexity. Straightforward rectangles are simpler (and cheaper) than decks with lots of corners, stairs, or built-in features.
- Details and access. Railings, posts, drains, and second-storey access all require extra care and time.
- Removing the old surface. Expect roughly an extra $1–$3 per square foot if demolition and disposal are needed.
While vinyl decking does sit at the higher end of the price spectrum, it’s worth looking at the bigger picture. A properly installed system can last 20–30 years or more, with very little maintenance. For decks over living space, where leaks can turn into expensive problems, that peace of mind is often the real value.
So, what should you budget?
As mentioned earlier, most homeowners in 2026 will land somewhere in that $15–$25 per square foot range, plus any repairs or removal work. That said, we often meet homeowners specifically requesting vinyl decking, only for us to find after a closer look that a different solution may suit their space, budget, or needs better. We’re always happy to guide you toward the option that truly makes the most sense.
