Graduation Balloon Decor in London Ontario

Graduation FAQs

• How far in advance should I book?

  For weekend events like weddings, baby showers, and milestone birthdays in London Ontario, we recommend booking 4 to 6 weeks out. Wedding season (May through September) and graduation season (May through June) fill fastest, and our custom build slots go early in those months. That said, we do take shorter-notice bookings if the calendar has space. Two weeks out is usually fine for smaller setups like birthday arches or table centerpieces. One week out is possible for a rush fee. If your event is tomorrow and you are reading this, message us anyway. We have pulled off same-day setups before for the right install size. The earlier you book, the more time Brenda has to design something that fits your specific colors, theme, and space rather than working from a standard template.

• Do you do graduation parties?

  Graduation season is one of our busiest stretches, typically running from May through June in London Ontario. We do balloon arches for backyard grad parties, number columns (Class of 2026 style), large balloon displays for school events and ceremonies, and full outdoor setups for family celebrations. Graduation balloon setups in London usually book up fast in April and early May, so the earlier you reach out, the more options you have for dates and custom designs. We can do school colors, graduation cap themes, photo backdrop walls, and name or number displays for milestone years. If you are planning a grad party for a family member, send us your date, the grad's school colors, and a rough idea of the space, and we will put together a quote. Most grad setups start around $160 for a simple arch and scale up from there for larger installs.

• Do you provide setup and installation at the venue?

  Yes, delivery and on-site setup are included in every quote. Brenda arrives before the event and installs everything directly in the venue so you do not have to manage logistics on your event day. For weddings and larger installations in London, we schedule arrival 2 to 3 hours before the event start. For smaller setups like birthday balloon arches or shower centerpieces, setup is typically 30 to 60 minutes. We coordinate with venues on access timing and work around any restrictions they have. If your venue has specific load-in rules, just let us know when you book and we will plan accordingly. Cleanup and removal after the event can be arranged at booking. You do not need to worry about breakdown or disposal. Everything from setup to cleanup is handled, so you can focus on your guests rather than the decor.

• How long do helium balloons last?

  Latex helium balloons float for roughly eight to twelve hours untreated, which covers a single event day but not much past it. Treated with a sealant on the inside, the same balloon holds for two to three days. Foil and mylar balloons, including number and letter balloons, hold helium far longer and typically float for three to five days, often up to two weeks indoors. Temperature is the variable people underestimate. A balloon that moves from a warm car into an air conditioned hall will visibly shrink, then recover once it warms back up. Cold shortens float time noticeably. This is also why most of our large installations in London are air-filled rather than helium. Air-filled arches, garlands, and walls hold their shape for days or weeks instead of hours, which is why they suit weddings, corporate events, and anything set up the night before. If your event runs across multiple days, tell us at booking and we will build it in the medium that lasts.

• 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.
