“It was absolutely wonderful working with them! The decor looked amazing! They put a lot of effort and care into it! We had our event in a park and they went to the park in person a few days before the event.”
“This is a delayed review and it truly deserves more than 5 stars. Aleks was so helpful for my event in Los Gatos. He did a wonderful job decorating the venue, which was at an outdoor winery.”
“We hired Balloon Bay for our baby shower. They were easy to communicate with and very thorough with details. Set up and take down were efficient. Great job!”

Quick answers on pricing, booking, and delivery. See our full FAQ for more.
Most balloon decorations range from about $200 for a simple arch or garland to $400–$800+ for a full event setup. The final price depends on the size of the installation, the balloon types used, and add-ons like backdrops, neon signs, or giant number balloons. Balloon Bay provides a free, custom quote for every event — call (650) 502-5077 or use our quote form with your date, venue, and theme.
Book 2–4 weeks ahead for weekend events, which fill up quickly, and as early as possible for large or holiday-season installations. That said, we can often accommodate same-week weekday requests. If your event is soon, call us at (650) 502-5077 and we'll check availability right away. Quote requests are answered within 24 hours.
Often, yes — for helium balloons and custom bouquets ordered early in the day, same-day balloon delivery across the Bay Area is frequently available.

We deliver, install, and tear down every order — there is no pickup or DIY assembly. A professional installs your arch, garland, or backdrop on-site, then returns after the event for full cleanup.
