Their name is ironic. You dont get to call your company "reliable on site services" and then proceed to be the least reliable service i have ever dealt with. We supplied a schedule of Monday - Friday, 6am - 2pm. These are the available hours for an employee to let you in the gate for service. Most weeks they either do not send someone for service, or if they do, they show up after business hours. Last week a driver called me after 3:30pm. I asked them to reschedule for someone to come out the next day. No one showed up. And its now 4 days later. The units are beyond disgusting. Do no reccomend

The sales person was extremely helpful and when there was a question about where the unit would be placed, a manager came out to look at the site and approve it.

Extremely disappointed in this company as their unit, located at a *heavily*-used athletic field complex, has not been serviced in *at least* two months and is a severe health hazard. I called the number posted on the door a few weeks ago and never got a call back. Today I tried calling their 24/7 line three separate times and, with a sum total of 45 minutes on hold, have still not reached anyone. Given the potential environmental impacts, they really should be more rapidly responsive. (Also, the individuals who contributed to creating this cesspool are animals and bear solidly 85% of the blame for the biohazard.)
Frequently Asked Questions About United Rentals - Reliable Onsite Services
How much does it cost to rent a porta potty?
Porta potty rental prices vary by size, type and quantity. For a price quote, please reach out to a member of our Reliable Onsite Services team.
How can I rent a portable restroom?
You can rent a portable restroom by submitting a request to our Reliable Onsite Services team. Once the form is received, a team member will contact you to confirm your requirements and quote you a price.
Should I rent a restroom trailer instead of a porta potty?
If you are looking for a more luxurious option, restroom trailers are a good fit, but if you're looking for a quick, budget-friendly option, porta potties will work best for you. Restroom trailers are larger and have running water, mirrors, laminate flooring and lighting. They do require water and electricity hookups, so if you do not have access to those, porta potties would be a better fit for you.
How many porta potties do I need for my jobsite?
A good rule of thumb for your jobsite is to have one portable restroom for every 10 workers in a 40-hour workweek, then increase the number of porta potties as your workforce and work hours increase.
How many handwashing stations do I need for an event?
You should have one handwashing station for every four porta potties. Portable sinks or hand sanitizer stations are required if your event includes food service.
What are your branch hours?
