Frequently Asked Questions...


  • How safe is it to rent a moonwalk?
    Please refer to all of the instructions and guidelines listed on your rental contract and on the unit itself. It is important that all users follow the rules listed on the contract and the unit. Our inflatables are all safety-rated and exceed industry safety standards. This means that they are built with safety in mind, using the latest in high-security designs and fire retardant materials.

  • Do you charge for set-up and/or delivery?
    There is never a charge for delivery and set-up within our normal service area of 15 miles or less, unless you have specific delivery time restrictions. Outside this area, there is a minimum surcharge. There are minimal fees if you have specific delivery time restrictions; i.e. we must deliver at a specic time, or if you have a one or two hour delivery window. We will be contacting you the day before your event with a delivery window. You must be home during your delivery window. If you are not home we will go on to the next delivery due to the fact we have a tight schedule. We will be able to deliver your unit at the end of our daily route. There will be a redelivery fee of $150 to cover fuel, labor and other expenses.

  • Do you require a deposit?
    Yes, we do require a deposit, depending on the amount of equipment rented. Deposits are typically 25% of your total rental cost, with a minimum charge of $50, but can vary based on amount of equipment rented. A credit card is required for the deposit.

  • What if I need to cancel my reservation?
    You may cancel your reservation, however, the deposit/amount paid is non-refundable.
       * If you cancel within 0-5 days of your reservation, your deposit/amount paid is non-refundable/forfeited.
       * If you cancel 6 or more days prior to your reservation, we will apply the deposit/amount paid to a new date within 1 year of your original party date.
       * Once the delivery truck leaves the warehouse, you are responsible for payment in full, NO EXCEPTIONS.
       * Cancellations due to weather are determined by Just 4 Jumps the morning of your event before we deliver. 

  • What is your policy if there is inclement weather?
    Inflatables cannot be used if there are winds of 20 mph (15 mph for some items) or more. The morning of your event, we monitor the weather using www.weather.com. If there is a 50% chance or more for rain or a prediction of winds 20mph or above, during the time of your event, you may decide to cancel the day of your event. If you decide to cancel your event, it must be prior to delivery. You will be able to get a raincheck of your deposit/amount paid, or it may be applied to your future rental. You MUST call us before 7am, the morning of your event, to cancel and to receive your raincheck. Please note, we MUST keep safety in mind at all times, so Just 4 Jumps reserves the right to cancel your rental due to inclement weather at any time.

  • -Rain-
    If there is a 50% or greater chance for rain during the scheduled time of your event, you may cancel or reschedule your event before 7am the morning of the scheduled delivery. However, if the forecast is calling for scattered showers, we recommend you continue with your scheduled delivery. If the forecast is for continuous rain throughout the day, we recommend you cancel or reschedule your event.

  • -Wind-
    Inflatables cannot be used in winds exceeding 20mph (15 mph for some items). If the forecast is for high winds, we will call to cancel/reschedule your rental. You will receive a raincheck if your event is cancelled and use it towards a future date in the same calendar year.

  • -Temperature-
    All inflatables can be used in a wide range of temperatures. If the temperature is expected to fall below 32 degrees, at any time during your event, we will call the morning of your event to cancel/reschedule your delivery. You will be able to receive a raincheck to use towards a future date in the same calendar year. Keep in mind, any temperature above this, the children’s activity will keep them very warm, and we recommend you continue as scheduled. Deposits will not be refunded for temperature cancellations above 32 degrees.

  • Are your units clean?
    All of our inflatables and equipment are meticulously cleaned and serviced after each rental. We want you to be comfortable in knowing that you are providing your family and guests with fresh and hygienic rental products.

  • Do I need to clean the moonwalk when the party is over?
    You, the customer, will need to inspect the moonwalk to make sure that there will only be a reasonable amount of cleaning done by our staff.

  • How much space do I need?
    We need a minimum of 2′ of clearance on all sides of the inflatable. A 17′x17′ area is required for 13′x13′ moonwalks, 19′x19′ area is required for 15′x15′ moonwalks, and 18′x22′ for most combo units. Slides, obstacle courses, and interactive games require a minimum of 5′ of clearance on all sides of the inflatbale. The area should be flat, free of debris, rocks, and trees. If you have an in-ground sprinkler system, please make sure the timer is not set to go on. We are NOT responsible for damage to any underground lines when setting up. If you are unsure as to the nature of your underground lines we recommend you call Julie at 811 before we setup. We can set up on grass, pavement, or indoors.

  • How strictly do you keep your schedule?
    We pride ourselves on our punctuality. We will always deliver our units on time or early.

  • How do I go about reserving an inflatable?
    You can call us at 219-779-0411 or reservations can also be made online on this website

  • Do I have to rent for the entire day or can I rent for shorter/longer periods of time?
    Our standard rates are for 7 hour rentals. Please pick no more than a 7 hour window for party times. We guarantee to deliver before your party start time and will not pick up until after your party end time. Please contact us for additional information.

  • When/How do I pay?
    All payments are due and expected at time of delivery. We will deduct your initial deposit from the total. We take cash, business checks (no personal checks) Visa, MasterCard, Amex or Discover. There will be a $25 returned check fee on all returned checks, NO EXCEPTIONS! 

  • Do you offer a discount for renting multiple units?
    Yes, please give us a call to determine discounts based on units rented. 

  • Will the Moonwalks harm my lawn?
    We cannot guarantee that the Moonwalks will not affect your lawn. In most cases, it will only temporarily flatten the grass, which should recover in a few days.

  • Does Just 4 Jumps have insurance?
    Yes. We carry a liability insurance policy. Please note that all individuals and/or companies that rent from Just 4 Jumps are required to sign a rental agreement prior to setting up the equipment. We cannot set up the inflatables until the rental agreement has been signed. You can be added as an additional insured to our policy for corporate/school events.

  • What type of power is required for an inflatable?
    The inflatable should be within 100ft. of a 110v outlet. We will supply the power cord, but we do ask that nothing else be plugged into the outlet/circuit being used. Some of our larger inflatables might need multiple outlets on separate circuits. Please contact us if you have any concerns about the power requirements for your inflatable.

  • Can I have an inflatable at a park or forest preserve?
    You must contact the park/forest preserve, in advance, to let them know that you would like to have an inflatable present. Many parks/forest preserves require a permit to have an inflatable set up and can take as many as 10 days to process. If a 110v outlet is not available, such as at a park, we can provide a power generator for an additional charge.

  • Who is responsible for underground utilities?
    Our units are staked into the ground for stability and safety. Therefore, the renter is responsible for having all utilities located prior to their party. We recommend you call Julie @ 811 3-4 days in advance. This service is free.

  • What should we do to get ready for our moonwalk rental?
    The first thing we like to tell people is…..”measure.” Make sure you know where you want your moonwalk rental, and make sure there is enough room. Also, make sure your outside plug is working. That means….plug something in and test it! We need electricity within 100 feet minimum. The second thing is, mow your lawn the day before, not the same day or the morning of set up. It will help keep the moonwalk clean for your kids’ enjoyment. Also, if you have a dog, please clean the yard of any waste before we come. It will help to keep odors away while your kids are jumping, and will prevent any soiling of our unit(s). If you have a waterslide rental, don’t water your lawn for a few days before your party. Waterslides use a lot of water, and if your grass needs it, it will absorb it a lot better if it is dry.

  • What are your safety rules/regulations?
    1. Always have adult supervision at ALL times, when children are in or around the unit.
    2. Children must remove their shoes prior to entering the unit.
    3. Keep the number of children in the unit at or below the number indicated in the rental agreement.
    4. No horseplay or flips.
    5. Absolutely NO gum, food, drinks, candy or silly string in the unit. These items, especially silly string, are very harmful to the vinyl. Violation of this rule can result in additional charges for cleaning.
    6. Keep smaller children out of the unit when older children are jumping. Allow a separate time for just the small children to participate and enjoy the fun.
    7. Do not move the unit from the set up location for any reason.
    8. Do not use near water or when fireworks are being used or will be used.
    9. Have FUN!

  • Can the company or organization sponsoring the event also be insured on the Just 4 Jumps policy?
    Yes. We are able to add the company/organization to our policy as being additionally insured. Please contact us for details.

  • Is it alright to tip the delivery person?
    Absolutely! These guys work hard spending their weekends setting up and taking down the equipment. If the delivery person does a good job, let him know. Tips range from $5.00 on, depending on equipment and difficulty of setup.
