Our commercial-grade slides are anchored properly during setup and meet all safety standards. We also provide safety guidelines and supervise the initial setup to ensure everything operates correctly before your guests arrive.

For summer parties in East Setauket, book at least one to two weeks ahead, especially for weekend events. Our most popular slides—the dual-lane racers and giant 22-footers—tend to book up fastest during peak season from June through August.
If you’re planning around popular local events or holiday weekends, even earlier booking helps ensure availability. That said, we do accommodate last-minute requests when possible, so it’s always worth calling even if your event is just a few days away.
Early booking also gives you more flexibility in slide selection and delivery timing. Plus, it’s one less thing on your party planning checklist, which busy East Setauket parents definitely appreciate.
Your rental includes the water slide, professional delivery and setup, all necessary safety equipment, and breakdown service after your event. We also provide clear operating instructions and safety guidelines for adult supervision during the party.
Our delivery team handles the heavy work—proper anchoring, water connection setup, and testing everything before guests arrive. After your party, we return to disassemble and remove everything, leaving your property exactly as we found it.
We service all of East Setauket and can accommodate most residential properties as well as local venues like community centers and parks. Setup typically takes 30-45 minutes, and we work around your schedule to minimize disruption to party preparation.
Absolutely. We carry slides designed for different age ranges, from gentle slopes perfect for toddlers and younger children to towering slides that thrill teenagers and adults. Most East Setauket parties include mixed age groups, so we help you choose equipment that works for everyone.
Our smaller slides work great for ages 3-10, while our larger slides can safely accommodate kids up to adult size. Many of our slides offer dual lanes, so siblings and friends can race safely side by side.
During booking, we discuss your guest list and recommend the right slide based on ages, space, and activity level you’re looking for. The goal is making sure every guest—from the youngest cousin to the competitive teenagers—has a blast.
Light rain doesn’t stop the fun—water slides work perfectly well in drizzle, and many kids actually prefer the extra excitement. For safety reasons, we do suspend use during thunderstorms or severe weather conditions.
If severe weather makes setup impossible or unsafe, we work with you to reschedule without penalty. East Setauket weather can be unpredictable, especially during summer storm season, so we build flexibility into our scheduling.
For covered venues or events with backup plans, water slides can often still work even during questionable weather. We’ll discuss options based on your specific situation and help you make the best decision for your party’s success.
Most residential properties in East Setauket have adequate space for our water slides. Generally, you need a flat area roughly 40 feet long by 20 feet wide for our standard slides, with additional clearance for safety zones around the equipment.
Our team conducts a brief space assessment during booking to confirm fit and identify the best placement. We consider factors like overhead clearance from trees or power lines, ground conditions, and access for our delivery crew.
Many East Setauket properties have beautiful, spacious yards that easily accommodate even our largest slides. If space is tight, we offer compact options that still deliver big fun. The key is matching the right equipment to your specific property and party size.
