Happy customer feedback
Rated 5.0 from 25 Yelp reviews across the Bay Area.
“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!”

Frequently asked questions
Quick answers on pricing, booking, and delivery. See our full FAQ for more.
How much do balloon decorations cost in the Bay Area?
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.
How far in advance should I book balloon decorations?
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.
Do you deliver and set up, or is it pickup only?
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. Delivery and setup are included across our core Bay Area service area; a small travel fee may apply for locations farther out, which we confirm in your quote.
What areas does Balloon Bay serve?
Balloon Bay is based in Saratoga and serves the entire South Bay, Silicon Valley, and Peninsula — including San Jose, Cupertino, Sunnyvale, Santa Clara, Campbell, Los Gatos, Los Altos, Mountain View, Palo Alto (94301–94306), Milpitas, Morgan Hill, Gilroy, Menlo Park, Redwood City, and Fremont. Each city page lists the ZIP codes we deliver to. If your city isn't listed, contact us — we regularly travel across the greater San Francisco Bay Area.
Can you match my exact theme and colors?
Yes — every installation is custom-designed and color-matched to your theme, invitations, venue, or Pinterest inspiration. Share your colors and style when you request a quote and we'll build the design around them, from soft boho neutrals to bold brand colors or a specific character theme.
How long do balloon decorations last?
A professionally built air-filled arch or garland lasts one to four weeks indoors in a climate-controlled space. Outdoors, lifespan is shorter — direct sun and heat can fade or pop balloons within a day — so we recommend shaded placement for all-day outdoor events. We build every installation to look its best through your event.
