What You Get Beyond the Bounce House

Every rental includes professional delivery, complete setup, safety orientation, and full breakdown service. We’re not dropping equipment in your driveway and wishing you luck—we’re making sure everything’s properly secured and ready for safe fun.

Our bounce houses feature commercial-grade construction with safety nets, entrance ramps, and proper ventilation. Each unit gets thoroughly cleaned and sanitized between rentals because cleanliness isn’t optional. We inspect every piece of equipment before it leaves our facility.

For Flanders families, we know summer parties often mean combining inflatables with other activities. That’s why we stock water slides, interactive games, carnival booths, and even arcade machines. Need tables, chairs, or a tent? We’ve got those too. One call handles your entire party rental needs, from the entertainment to the essentials.

How far in advance should I book my bounce house rental in Flanders?

Book at least 2-3 weeks ahead for the best selection, especially during peak party season from May through September. Weekend dates fill up fastest since that’s when most birthday parties happen. We do accept last-minute bookings when inventory allows, but your options might be limited. If you’re planning a party during graduation season, school breaks, or around major holidays, give yourself even more lead time. Popular themed units like superhero or princess bounce houses get reserved quickly. The earlier you book, the more flexibility you have with delivery times and equipment choices. Plus, you can cross “entertainment” off your party planning checklist and focus on the cake and decorations.
Every bounce house gets inspected before delivery and meets commercial safety standards. We’re talking reinforced seams, proper anchoring systems, and safety nets that actually work. Our crew handles all setup and secures everything according to manufacturer specifications. Each rental includes a safety orientation where we explain capacity limits, age guidelines, and basic supervision tips. We provide written safety rules you can post for parents and kids to see. No shoes, no food, and adult supervision—the basics that prevent 99% of accidents. We’re fully insured and licensed because this isn’t a hobby for us. Our equipment undergoes regular maintenance and replacement when needed. We won’t deliver anything we wouldn’t let our own kids use.
Absolutely. Every single rental gets a full cleaning and sanitization process before it goes to the next customer. We vacuum out debris, wipe down all surfaces, and use commercial-grade disinfectants that are safe for kids but effective against germs. This process became even more thorough after COVID, but honestly, we were already pretty obsessive about cleanliness. Parents in Flanders expect equipment that looks and smells fresh, and that’s exactly what we deliver. Our cleaning routine includes checking for wear and tear, so you’re getting equipment that’s not just clean but also in excellent condition. If something doesn’t meet our standards, it doesn’t go out to your party.
Most of our bounce houses work great in light rain, but safety comes first. If we’re dealing with heavy rain, strong winds, or storms, we’ll work with you to reschedule at no extra charge. We monitor weather forecasts and will contact you if conditions look questionable. For Flanders families dealing with typical Long Island summer weather, a little drizzle usually isn’t a problem. The kids often love bouncing in light rain—it’s like a bonus water feature. But if lightning’s in the forecast, we’re not taking chances. We offer flexible rescheduling because we know you’ve already planned food, invited guests, and probably bought decorations. Our goal is helping you have a great party, even if Mother Nature doesn’t cooperate with your original timeline.
We absolutely work with schools, churches, corporate events, and community organizations throughout Flanders and Suffolk County. Our inventory includes larger units perfect for bigger crowds, and we can coordinate multiple rentals for major events. Corporate clients love our custom branding options—we can add your company logo or event messaging to create a professional look. For school events, we offer special packages that maximize fun while staying within typical PTA budgets. We handle all the logistics for larger events, including site surveys, permit assistance, and coordinating with other vendors. Whether it’s a company picnic, school carnival, or community festival, we scale our service to match your event size and requirements.
Your rental price covers everything: delivery, professional setup, safety orientation, and complete breakdown service. No hidden fees, no surprise charges, no “oh by the way” add-ons when we arrive. The price we quote is what you pay. For Flanders locations, delivery is included within our standard service area. Setup takes about 30 minutes, and we handle all the technical stuff—anchoring, electrical connections, and safety checks. When the party’s over, we return to break everything down and haul it away. The only extras you might want are additional services like tables, chairs, or concession machines. But the bounce house rental itself is all-inclusive. We believe in transparent pricing because surprise costs are the last thing you need when planning a party.
