Private Events

For a family celebration, the goal is simple — the decor should feel like it was made for your specific event, not pulled off a shelf.

Birthday and Milestone Celebrations

A one-year-old’s first birthday and a parent’s sixtieth call for two completely different builds. We adjust color palette, scale, and design complexity based on who’s being celebrated and what kind of party it is. Some clients want a single statement arch near the cake table. Others want the whole room transformed.

Weddings and Showers

Wedding decor has to share space with florals, table linens, and lighting the couple already spent months choosing. We keep balloon garlands and arches proportional to the room and the rest of the design, rather than letting them dominate. A lot of Mequon couples pair a garland with real or faux greenery for a look that reads more organic in photos.

Graduations and Family Events

The age range of the guests at these parties can be from toddlers to grandparents. Venues can vary from backyards to halls rented out. We build around the guest of honor’s school colors, class year, or a family theme, and scale the design up or down depending on the space.

Corporate Events

A corporate installation has one extra requirement a private party doesn’t: it has to look like your brand, not just look nice.

Employee and Corporate Celebrations

Work anniversaries, holiday parties, and staff milestones need decor that fits an office environment. We aim for something that reads as thoughtful and put-together, not like a birthday party set up in a conference room.

Brand Promotions and Retail Events

For store activations and product launches, we match balloon colors to your actual brand guidelines, down to the Pantone number if that matters to you. The goal is decor that looks intentional in photos and doesn’t clash with your signage or packaging.

Grand Openings and Major Announcements

New locations and major announcements get one shot at a first impression. We typically build a large entrance piece, an arch or a full display, sized to be visible from the street and hold attention long enough to bring people through the door.

Balloon Designs We Build

We work with five main design types. Which ones make sense for your event depends mostly on the venue and the occasion.

Arches

Most people photograph the arch before anything else, so we treat it as the anchor piece. It can be a single solid color, a gradient blend, or a mixed-texture design, and we build it to the exact width and height of whatever doorway or stage it's framing.

Garland

Garlands don't sit still the way an arch does. They wrap around a staircase, run the length of a head table, or drape across a backdrop wall. We mix balloon sizes within the same garland to give it more depth than a uniform row of same-size balloons would have.

Columns

Columns go up in pairs, usually flanking an entrance or a stage. Because they're tall and narrow rather than wide, they hold their shape better outdoors than a garland does, which makes them a common choice for tented or lawn events in the area.

Centerpieces

These stay low enough that guests can still see each other across the table. We'll build a smaller version for a formal seated dinner, and a bigger one for a buffet or welcome table where you want more visual presence.

LED Letters

A name, age, or single word spelled out in light, with balloons clustered around the base. This works especially well for evening events, since the letters keep the display visible in photos even after the natural light is gone.

Frequently Asked Questions

How far in advance should I book balloon decor in Mequon?
Four to six weeks is a safe window, especially if you’re planning a wedding or booking during spring or the holidays. If it’s a smaller birthday or shower, we can sometimes work with less lead time depending on our schedule.
It depends on scale. A single arch runs less than a full room build with garlands, columns, and centerpieces combined. The easiest way to get an accurate number is to fill out our estimate form with your event details.
Yes. Outdoor jobs use different materials and rigging than an indoor install, since heat and wind put more stress on balloons than a climate-controlled room does. We account for that when planning an outdoor setup.
Yes. If you have a Pantone code, a brand style guide, or wedding swatches, we’ll build the color blend to match rather than guessing at “close enough.”

Yes, for most venues. Setup and teardown are both part of the job, so you’re not stuck disposing of balloons after your guests leave.
