What You Need to Know About Renting Inflatables in O'Fallon, MO
O'Fallon yards and neighborhoods: As the largest city in St. Charles County (95,000+ residents), O'Fallon has an incredible range of neighborhoods — from established communities near Fort Zumwalt Park to newer developments in the Winghaven area. Most yards easily accommodate our bounce houses and combos. Grass is our first choice for setup — we anchor with ground stakes for a secure hold. Each inflatable needs one standard 110v outdoor outlet within about 50 feet. No nearby outlet? We rent generators that keep everything running all day. We also set up on driveways, concrete, and indoor gym floors using sandbags.
Fort Zumwalt School District: The Fort Zumwalt School District is the largest in St. Charles County and is headquartered right here in O'Fallon at 555 E. Terra Lane. The district operates three high schools (Fort Zumwalt West, Fort Zumwalt North, and Fort Zumwalt East), plus multiple middle and elementary schools throughout O'Fallon including Mt. Hope Elementary, Westhoff Elementary, Forest Park Elementary, J.L. Mudd Elementary, and North Middle School. O'Fallon is also served in parts by the Wentzville R-IV and Francis Howell R-III districts. We serve schools across all three districts for field days, PTO carnivals, and celebrations.
