09 / From the owner

Family-operated, not a chain

We began with a single truck and a few units, and that hands-on approach hasn't changed. When you call, you reach me or someone I'd let park on my own property. We're family-operated, so when something isn't right, we own it and sort it out that same day.

I track every job on one board in the office, and each driver reviews it before heading out. When we tell you Tuesday morning, that means Tuesday morning. If anything changes, I pick up the phone before you need to.

Frequently asked

How frequently do units get serviced?

All rentals come with one service visit per week. High-traffic sites and larger crews can schedule a second weekly visit.

How do extended rentals work?

We assign a regular weekly service day and leave the unit in place until you let us know it's time for pickup.

Are ADA-accessible units available?

They are. Our ADA-accessible units feature step-free entry, an extra-wide door, grab bars, and space to maneuver a wheelchair.

How much lead time do I need for an event weekend?

Two to three weeks works well for spring and summer weekends. Reach out earlier for holiday weekends.

What happens during the weekly service visit?

We empty the tank, scrub and disinfect the interior, restock paper and sanitizer, and inspect the door and latch.
