The party takes weeks to plan. This part takes about four minutes.
We're a family business a few miles east in Crown Point, and St. John is one of the towns we deliver to most. We drop the bounce house off clean, set it up, stake it down, and come back for it. Your only job is the cake.

Your date comes first
Summer Saturdays go first, and if your party is in one of St. John's parks you need longer than you think — the town wants our insurance paperwork at least seven working days before we set anything up. Set your date and the grid below only shows what's actually free.
A deposit holds your date. Balance is due at setup.

Step 1 — Who's doing the jumping?
Step 2 — Where are we setting up?
For the under-sixes
Under about 6, a slide mostly creates a queue and a climb. An open jump area keeps everyone bouncing at once. Most standard bounce houses are built for around 5 to 6 kids of similar size at a time.
Grassy backyard: we anchor with stakes, so mark any sprinkler heads or underground lines before we arrive. Mow no later than the day before, and clear pet waste and toys from the setup area.
Driveway or concrete: doable in a lot of cases, but it changes how we anchor. Tell us at booking that there's no grass so we bring the right setup.
Park, school, or church lot: tell us which one when you book. St. John allows inflatables in its parks, but only with prior approval from the Parks Department, and it has to be listed on your permit application. You'll also need a plan for power — we need one standard outlet within 50 feet, which often means a generator.
For seven and up
Seven-and-up burns out on a plain bounce in about twenty minutes. A slide or a themed unit holds them for the whole party. Both of these work for this age.

When the ages are all over the place
With a wide age range, one inflatable turns into a bottleneck and the little ones get bounced around by the big ones. A large combo plus a game splits the crowd and keeps the teenagers and adults busy too.

Driveway or concrete: doable in a lot of cases, but it changes how we anchor. Tell us at booking that there's no grass, and keep in mind two units need two clear areas.
Park, school, or church lot: tell us which one when you book. Two inflatables usually means two outlets or a generator, and in a St. John park both have to be declared on the permit application in advance.

Clear any pet messWe ask for this every time, and every time somebody is glad we did.
Find the nearest outletOne standard household outlet runs most bounce houses, and the blower stays running the whole time it's in use.
Mark buried linesInflatables get staked into the ground. If we don't know where the lines are, we can't avoid them.

The events we turn up for in St. John
Backyards in the Gates, school field days, church festivals, and the odd graduation party that ran long. If it's happening in St. John, we've probably delivered to it.
Birthday parties
The bread and butter. Backyard, driveway, or grandma's place over in Homestead Acres.

Block parties and subdivision events right across the west side of town.

Fundraisers and youth clubs

Subdivision by subdivision
St. John is a town of neighbourhoods, and most of them are newer builds with flat, fenced back yards — close to ideal for an inflatable.
Where our trailer ends up
One thing worth checking here: newer estates often have narrow side gates. Measure the gap before you pick the biggest combo.
The Gates of St. JohnHomestead AcresHomestead VillageFairway EstatesSchillton HillsLake HillsHeron LakePrairie West
Newer street that isn't listed yet? No problem — put your address in at checkout and the delivery fee comes back straight away.
St. John is one of the few towns around here that spells out exactly how this works. Inflatables are allowed in the parks, but they have to be approved in advance and listed on your permit application, and we have to file a certificate of insurance with the Parks Department at least seven working days before we set up. Give us that much notice and it's straightforward.
Tap a park for what it offers and what to watch for.
Veterans Civic Park9401 Civic Dr
The biggest of the rentable options — two pavilions, picnic tables and grills, plus basketball, volleyball, tennis, three baseball fields and a concession stand. If your guest list is heading past 100 people you'll also need the Parks Department's Special Event Form on top of the standard booking.
Prairie West Park9359 W. Oakridge Dr
A pavilion beside a pond with a playground next to it, which keeps younger guests busy while the adults set up. Reports are that there's power at this pavilion — worth confirming with the Parks Department that it's usable for a blower before you rely on it rather than a generator.
Schillton Hills Park8951 Franklin Dr
Pavilion, picnic tables, a barbeque grill and a playground. Note the town's rule that no additional grills are allowed in the park, and no driving or unloading on the grass — so we'll need a reasonable path from the parking area to wherever the unit is going.
Homestead Acres Park and Larimer Park9921 Olcott Ave and 9375 Woodland Dr
Two neighbourhood options. Homestead Acres has a pavilion, picnic tables and a walking and bike trail; Larimer has a pavilion, a pond, a basketball court and a baseball field. Both are good for a straightforward party — and remember festivities run from 10am until dusk, with setup allowed from 9am.
Booking runs through the St. John Parks Department at 9350 Hack St, Building 2 — (219) 365-6236 — with payment at the Clerk-Treasurer's office. Tell us the park as soon as you've booked it so we can get the insurance paperwork in on time.
Who you're actually renting from
How Bouncy B's began
Nine years ago we rented a bounce house for a Fourth of July party. The communication was poor and the service was worse. So we bought our own inflatable, then bought a small local rental company that was closing — a trailer, a phone number, and a handful of units.
That's Bouncy B's. The name comes from our three kids: Brayden, Bryce and Briella — they're the ones in the logo. Ray, Meghan and the kids are still the people answering the phone and pulling into your driveway.
How much does it cost to rent a bounce house in St. John?
Standard bounce houses start at $160. Combo units with a slide run from $247.20 up to $360.50 depending on size. Delivery is quoted separately against your St. John address at checkout, so you see it before you pay anything.
When should I reserve my date?
As early as you can. Popular weekends, the summer holidays and graduation season fill up quickly here, and the earlier you reserve the more of the catalog you get to choose from.
How many kids fit in a bounce house at once?
Most standard bounce houses are designed for roughly 5 to 6 children of similar size at a time. Exact occupancy is listed on each rental page, and kids of similar age and size should bounce together.
Can we set up in one of St. John's parks?
Yes, and St. John is unusually clear about how. The town's pavilion rules allow temporary structures including inflatables, but only with prior Parks Department approval, and you have to list them on your permit application. The town also requires the company supplying the inflatable to file a certificate of insurance naming the Town of St. John Parks and Recreation Department as an additional insured at least seven working days before setup — so tell us early. Pavilion bookings are $100, or $50 for non-profits, plus a $100 security deposit, paid at the Clerk-Treasurer's office.
What happens in bad weather?
Safety comes first. If severe weather is expected we may recommend postponing, and rescheduling options may be available. For inflatables we ask for at least 24 hours' notice on a weather-related reschedule, so call or text us as soon as the forecast turns.
Can you set up on a driveway instead of grass?
Concrete and pavement work in many cases, but it changes how we anchor, so tell us during booking if there's no grass at your setup spot.
Does a bounce house need electricity?
Yes. Most bounce houses run on one standard household outlet within 50 feet of the setup area, and the blower needs to stay running the whole time the unit is in use. At Prairie West or Larimer Park that normally means bringing a generator.
How are the bounce houses cleaned?
Yes — every inflatable is cleaned and sanitized before each rental, not just at the end of a busy weekend.
When do I pay, and what's the cancellation policy?
A deposit reserves your rentals for your date and is non-refundable, since it takes those units off the calendar. If you only paid a deposit, the remaining balance is due at setup by cash or check. Weather-related rescheduling options may be available with proper notice.
Other towns we cover
We're based in Crown Point, a straight run east from St. John along 93rd. If your town isn't listed, call or text and ask, because the answer is usually yes.
If you are taking measurements for a structure such as a building or fence, please provide the height of the structure here. If height does not apply to the wash, for instance for a gutter wash, leave this field empty. Please note if you enter a value here after taking measurements, you will need to take measurements again.
