Balloon decoration questions, answered

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. Full installations like arches, garlands, and backdrops are best booked ahead, but we keep some flexibility for short-notice weekday events. Call (650) 502-5077 with your date and location and we'll confirm the fastest delivery we can offer.

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.

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.

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.

Most of our installations are air-filled on frames rather than helium, because air-filled designs last far longer (weeks vs. hours), hold their shape, and create the lush 'organic' look you see in arches and garlands. We can include helium foil or number balloons on request for specific floating accents.

Yes — a deposit reserves your event date, with the balance due before or on the day of installation. We accept standard payment methods and provide itemized quotes and invoices, including for corporate clients who need to process payment through procurement. Details are confirmed when you book.

We decorate baby showers, gender reveals, kids' and milestone birthdays, weddings, graduations, grand openings, and corporate events of every size. Popular setups include balloon arches, organic garlands, columns, giant number and letter displays, and themed photo backdrops — all customizable to your occasion.

Often, yes — especially for weekday events. Weekend dates fill quickly, but we keep some flexibility for short-notice requests. Call (650) 502-5077 with your date and we'll confirm availability and the fastest setup we can offer.

Just four things to start: your event type, date, venue or address, and your theme or color palette. From there we'll recommend a design and provide a free quote. Photos or a Pinterest board help us match your vision precisely, but they're optional.
