It’s Your Event, We Make it Pop!

Welcome to Wilhelmina Balloon Installations. Located in Port Washington, Wisconsin just north of Milwaukee. Our specialty is working with clients to design unique balloon displays for all of your important events, from weddings and corporate gatherings to your best friend’s birthday.

We use biodegradable latex balloon, made in the USA, which decompose as quickly as an oak leaf. The majority of our designs are air-filled however helium is available. We also offer latex free options.

Wilhelmina provides professional balloon décor to Ozaukee County, Milwaukee, Sheboygan, Washington, and surrounding areas. 

It’s your event, we make it POP!

Whether we are designing for your front yard or an event space we can work together to make sure the special birthday is perfect.

Cake Toppers

All good parties have cake! Cake Toppers are a great way to add that extra little pop to your sweet treat. Also highly preferred over candles because no one needs to know how old we are, germs are spread when blowing out candles, and wow so much unnecessary fire! : )

Special Events

Lauri was super kind and easy to work with! Great communication and she made sure my order was exactly what I was looking for. I ordered a little last minute so I was very appreciative that she was willing to fit me in to make my sisters 18th birthday even more special! The design was beautiful and very well put together. Thank you for the amazing service and balloons!
