Install type
Balloon columns and number balloons in London, Ontario
Freestanding, weighted, and built in your colours. The install that works in venues where nothing is allowed on the walls.
Columns solve a problem the other install types cannot. They stand on their own, weighted at the base, attached to nothing. That makes them the answer for venues with rules about walls and ceilings, for outdoor setups where there is nothing to build against, and for events where the room has to be cleared quickly afterward.
What balloon columns cost
A single freestanding column starts at $149. Columns topped with a large foil number or letter run $249 to $325. Oversized mosaic numbers, the four-foot floor-standing kind you fill with balloons, and matched pairs flanking an entrance sit at the upper end. Most milestone setups in London are a pair rather than a single, because two columns framing a doorway, a cake table, or a stage read as an intentional install where one alone reads like a leftover.
Sizes, and what actually reads across a room
Standard columns are six to seven feet tall, which puts the top just above head height so they stay visible once guests are standing. Large foil numbers are about three feet and work mounted on a column base or floating in a cluster. Mosaic numbers stand four feet and hold their own as a photo backdrop without anything else around them. For a Class of 2026 grad setup or a milestone birthday, a pair of numbers on column bases at the entrance is the build we do most.
Where they work best
Milestone birthdays, graduations, anniversaries, retirements, and grand openings. Anywhere a specific number is the point of the event, a column puts that number at eye level and in every photo taken at the door. They also travel well between rooms, which matters for events that move from a ceremony space to a reception space.
Outdoors they need extra weight or an anchor, because wind moves a freestanding column faster than people expect. Tell us if the setup is outdoors and we will build the base accordingly rather than leaving you to hope. Sizing details are in the FAQ. If you want something spanning a doorway instead of standing beside it, look at balloon arches, and for table-level pieces see balloon centerpieces.

Column and number balloon questions

Do you offer rentals or is everything custom-built?
Everything we make is custom-built for your event. Balloon installations are not rental items, they are assembled fresh for each booking using new materials matched to your colors, theme, and space. There is no standard inventory you are pulling from. Brenda designs and builds every arch, wall, column, and centerpiece specifically for the event it is going to. This means your balloon decor in London will not look like what showed up at someone else's event last weekend. It is built for your date, your venue, and your color palette. Because each build is custom, pricing is based on size, complexity, and material cost rather than a flat rental fee. For ongoing corporate accounts that want recurring setups, we can build a standing arrangement to keep costs predictable. Message us with your event details and we will quote it accurately the first time.

How tall are balloon columns and number balloons?
Standard freestanding balloon columns run six to seven feet tall, which puts the top just above head height so they read from across a room. Number and letter balloons come in a few sizes. The common large foil numbers are about three feet tall and work mounted on a column base or floating in a cluster. Oversized mosaic numbers, the kind you fill with balloons and stand on the floor, are four feet tall and hold their own as a photo backdrop on their own. For a milestone birthday or a Class of 2026 grad setup in London, a pair of numbers on column bases flanking an entrance or a cake table is the setup we build most. Columns are freestanding and weighted, so they do not need to attach to anything, which makes them the easiest option for venues with rules about walls and ceilings. Outdoors they need extra weight or an anchor because wind moves them. Tell us the ceiling height and where you want them standing and we will size accordingly.
