This review is LONG overdue. We’ve been using German for Jumpers for our son since he was 2 years old! We just used him again for our son’s 12th Birthday this past Sunday. German, as usual, was prompt, and made the set up as easy as can be. Tear down was also a breeze for him and his crew. We appreciate you so much German! I’ve also called him for my friend’s kid’s parties in the past, and we’ve never had an issue. He is AMAZING!!

We’ve always had excellent service with making a reservation, delivery & pick up. The cost is worth it to keep the kids entertained for hours. I’ve used CalJumps several times and I highly recommend them!

Getting a mini combo jumper from Cal Jumps made my little girl’s day! They arrived early to set up so we had less stress close to party time and accommodated my last minute reservation change (a day or two before the party) with no problem. I’ll keep them in mind for future parties.

We rented a jump house, tables and chairs from these guys again this last weekend for our daughter’s first birthday party. As usual, the service we received was perfect.
Their way of communicating beforehand (the submission of a request for what you want and when you want it followed by several emails to ensure you know what you’re getting and when) helps to alleviate any anxiety you might have about your event and their part in it. They can’t help you if your struggling over your menu…. But they can ensure you have what you need to make your party a success.
They arrived promptly and had everything set up very quickly and safely about an hour before our planned time taking even more stress off because I wasn’t worried when they would show up.
All of their supplies are well maintained and in great condition. Lastly, when they arrived to pick the supplies up at the end of the day, they had everything packed up before I even knew they were there. Again…zero stress.
On top of their great service, is the value. The cost of renting their supplies is truly competitive and I never think I am being overcharged.
So, if you need party rentals, these are the only people I recommend and we will continue to use them every time we need something.
