Choose helium when you need balloons to float — ceiling clusters, single releases, bunches tied to a chair. Choose air-filled for anything with a shape: arches, garlands, backdrops, columns and letters. Air-filled lasts days; helium lasts hours.
Why most professional setups are air-filled
An arch is not a row of floating balloons. It is balloons packed onto a frame, and the frame is what gives it the curve. The same is true of a garland, a column or a wall of balloons. None of it needs helium and none of it would hold its shape with helium, because a floating balloon pulls upward against the structure rather than sitting in it.
This surprises people who assume helium is the premium option. It is not — it is a different tool, and for most of what makes a room look decorated it is the wrong one.
Where helium genuinely earns its cost
- Ceiling balloons with ribbons hanging down. There is no other way to do it.
- A single large foil number floating beside the cake.
- Bunches tied to chairs or a gate that need to stand upright without a frame.
- A release moment — though these are increasingly avoided for environmental reasons, and we would rather talk you into something else.
Cost
Helium is a bought gas and the price moves; air is free. The difference is mostly the gas, not the labour, so a helium element added to an air-filled setup is a small addition rather than a different price bracket. If a quote for a mostly air-filled setup jumps sharply when you add “some floating ones”, ask what specifically is being added.
What to say when you book
You do not need to specify. Describe what you want the room to look like and whether it needs to survive past the day, and a decorator who knows what they are doing will pick. If it must still be up the next morning, say that sentence — it is the one that changes the build.
See what a full setup involves on the pricing page, or how long a finished one holds in how long balloon decoration lasts.
