Getting a bounce house or waterslide delivered to your backyard is one of the easiest ways to make a birthday party feel like a real event. The Jump High Rentals crew handles setup and pickup, so your main job is making sure the yard is ready when they arrive. A little prep work the day before goes a long way toward a smooth delivery and a safer play area for your guests.
This guide walks you through exactly what to do, from measuring your space to greeting the team at the door.
Measure Your Space Before Booking and Before Delivery Day
The single most useful thing you can do before your rental date is measure your backyard. Not once, but twice: once when you book, and again a day or two before delivery.
Why twice? Yards look different when you mentally picture them versus when you stand there with a tape measure. Patio furniture, a trampoline you forgot about, or a garden bed that juts out further than you remembered can all shrink the usable area quickly.
When you measure, account for the inflatable itself plus clearance on all sides. Most units need a few feet of buffer around the perimeter so the blower can run freely and kids have a safe landing zone near the entrance. If you are unsure how much clearance a specific unit needs, ask when you book. The Jump High Rentals team is happy to walk through dimensions with you so there are no surprises on delivery day.
A few things to note while you measure:
- The height of any overhead obstacles, including tree branches, patio covers, and string lights
- Whether the flattest part of your yard lines up with the access path from the gate
- Any corners or narrow passages the crew will need to navigate with the inflatable
Sharing this information upfront helps the team plan the best placement for your yard and keeps setup moving quickly.
Clear the Setup Zone and Open the Access Path
Once you know where the inflatable is going, the next step is clearing that entire area completely. This is the part of backyard prep that makes the biggest difference on delivery day, and it is mostly just a matter of moving things out of the way.
Walk the setup zone and remove everything: patio chairs and tables, kids' bikes, garden hoses, sprinkler heads that stick up above the grass, pet toys, potted plants along the edges, and any yard tools leaning against the fence. Even small items left on the ground can become tripping hazards once a large inflatable is being positioned.
Then walk the access path from your gate or side yard entrance all the way to the setup zone. The crew will be carrying or rolling a large, packaged inflatable through that route, so the path needs to be clear and wide enough to move through comfortably. If your gate has a latch that sticks or a lock that requires a code, leave a note for the team or plan to be outside when they arrive.
A few common access issues worth checking in advance:
- Gates that are narrower than the inflatable's rolled width (confirm gate width with the rental company if you are unsure)
- Low-hanging branches or overhead wires along the side yard
- Steps, raised thresholds, or uneven pavers that could make rolling equipment difficult
- Pets that need to be secured before the crew arrives
Keeping pets inside or in a separate area of the yard during setup is a good habit. It protects your pets, keeps the crew focused, and prevents any unexpected delays.
Check Power, Water, and Surface Before the Crew Arrives
Most inflatables use a continuous-run blower to stay inflated throughout the rental period. That means you need a working outdoor outlet within a reasonable distance of the setup area. Before delivery day, locate your nearest outdoor outlet and test it to make sure it is functioning.
If the outlet is far from the setup zone, you may need an extension cord. Check with Jump High Rentals about cord length and gauge recommendations so the blower gets consistent power. Using an undersized cord can affect performance, so it is worth confirming the details ahead of time.
For waterslides and other water-based inflatables, find your outdoor hose bib and make sure the hose reaches the connection point on the unit. If your hose is short or stored in a different part of the yard, move it to the setup area the night before. Also think about drainage: water will run off the slide and pool somewhere, so position the unit where runoff flows away from the house foundation and does not create a slipping hazard on hard surfaces nearby.
Surface matters too. A flat, level grass area is the easiest and safest setup surface for most inflatables. If your yard has a noticeable slope, uneven ground, or a mix of grass and concrete, mention that when you book. The team can advise on whether a specific unit will work safely in your layout or whether a different placement makes more sense.
Handle Gates, Pets, Slopes, and Other Backyard Quirks
Every backyard in Orange County is a little different, and most quirks are easy to work around as long as the rental company knows about them in advance. The key is to mention anything unusual during booking rather than discovering it together on delivery day.
Slopes are one of the most common questions. A gentle slope is often manageable depending on the unit and placement, but a steep grade can affect anchoring and safe operation. If your yard is not perfectly flat, describe it when you call or book online so the team can set expectations and bring the right anchoring approach.
Narrow side yards, low fences, shared driveways, or HOA access rules are also worth flagging early. If your community has specific delivery windows or requires advance notice for vendor access, handle that coordination before the rental date so the crew is not waiting at a gate.
A few other backyard details that are helpful to communicate:
- Exposed sprinkler heads or irrigation lines that could be damaged during staking
- Low utility covers or drainage grates in the setup area
- Overhead utility lines near the inflatable's intended location
- Landscaping edges with sharp borders or decorative rock that borders the grass
None of these things are deal-breakers in most cases, but knowing about them ahead of time helps the crew work efficiently and keeps the setup process smooth for everyone.
Confirm the Schedule and Be Ready to Greet the Team
The day before your party, take a few minutes to confirm your delivery window with Jump High Rentals. Most rental guides for Orange County parties recommend a quick reconfirmation call or message so both sides are aligned on timing. This is especially useful if your party starts early or if you have other vendors arriving the same morning.
On delivery day, plan to be home and available when the crew arrives. You do not need to supervise the setup, but being present means you can answer any last-minute questions about placement, point out the outlet location, and confirm the setup zone is exactly where you want it. It also gives you a chance to do a quick walkthrough with the team before they leave so you feel comfortable with the unit before guests arrive.
A few things to have ready when the crew shows up:
- The gate unlocked and the access path clear
- Pets secured inside or in a separate yard area
- The outdoor outlet accessible and tested
- The hose positioned near the setup zone if you booked a waterslide
Once the inflatable is up and the blower is running, the crew will walk you through basic operation and safety guidelines. That conversation usually only takes a few minutes, and it is a good time to ask any questions you have about the unit before the party starts.
When your backyard is prepped and the logistics are handled, the rest of the day is yours to enjoy. Jump High Rentals takes care of setup and pickup, so you can focus on the cake, the guests, and making sure the birthday kid gets the first bounce.
