Our most popular installation, the balloon arch works for birthdays, baby showers, weddings, graduations, grand openings, and corporate events. We design organic (asymmetric, garland-style) arches as well as classic spiral arches, and can frame a doorway, stage, photo backdrop, or dessert table. A corporate balloon arch is normally sized to a ballroom entrance or a stage frame rather than a doorway, and color-matched to the company’s brand palette. Not sure whether you need an arch or a garland? An arch stands on its own frame and marks an entrance or a focal point, while a garland drapes over something that is already there. Our guide to balloon garland vs. balloon arch explains which one suits which event, and how to combine them.
Every arch is built with premium matte, chrome, and confetti balloons in your exact colors, with optional giant numbers, custom lettering, neon signs, and fresh florals. We deliver across San Francisco, Silicon Valley, and the South Bay, install securely on-site, and return for full teardown so you never touch a balloon.
Most of our arches go up in the South Bay and the city. For local details, venues, and ZIP codes, see balloon arches in San Jose and balloon decorations in San Francisco; every arch price, by size, is on our balloon arch cost guide.
Outdoor arches need more planning than indoor ones. Direct sun fades latex within hours, balloons pop more easily above 90°F, and wind is the main safety risk for a freestanding frame, so we weight every base and favor air-filled builds outside. See indoor vs. outdoor balloon decorations for what holds up in Bay Area weather.
We design and install balloon arches across the San Francisco Bay Area — including San Jose, Saratoga, Cupertino, Sunnyvale, Santa Clara, Mountain View, and Palo Alto — each one custom color-matched to your theme with professional delivery, setup, and full teardown included. Pair your balloon arches with a matching garland, backdrop, or helium bouquet for a complete, photo-ready look.

Balloon Arches FAQs
How much does a balloon arch cost?
For private events, balloon arches typically start around $200 for a compact organic half-arch and range to $400–$800+ for a large full-frame or themed arch with giant numbers and a backdrop. Corporate arches are quoted from an $800 minimum engagement per event. The price depends on size, balloon types, and add-ons. Call (650) 502-5077 or request a free quote with your colors and venue for exact pricing.
How long does a balloon arch last?
Our air-filled arches last one to four weeks indoors in a climate-controlled space, and a full day or longer outdoors in mild shade. Direct sun and heat shorten that, so outdoor arches get extra reinforcement and weights.
Indoor vs. outdoor lifespans, and how to make an arch last longer →
What's the difference between an organic and a classic arch?
An organic arch is an asymmetric, garland-style cluster mixing balloon sizes and finishes for a modern, textured look — ideal over tables and backdrops. A classic arch is an even, symmetrical spiral that frames a doorway or entrance. We build both; share your inspiration and we'll recommend the right style.
Do you set up and take down the arch?
Yes — delivery, professional on-site installation, and full teardown are all included. We secure the arch so it stays put for your event and return afterward for complete cleanup, whether you're at home, a venue, or an outdoor space.
Can you build an outdoor balloon arch?
Yes — outdoor arches are popular for graduations, grand openings, and garden parties. We reinforce and weight them for wind, and recommend a shaded spot to protect the balloons from direct sun. Let us know the location when you book so we plan the right build.
