I attend a large festival each March that the porta potties are rented from this company. Over ten days and one hundred and ten units on-site, both regular and ADA. These potties are well maintained, pumped and cleaned for 3000 campers. This company is wonderful. They go over and above to service the needs of the group and are a gem to work with. I highly recommend the company, not just for price, but for expertise and being a caring company.


Toilet went out at our house so we got a porto potty from SOS. Very timely in delivery, payment is reasonable, service was excellent.


SOS is a nice company that cares about the community and does its best to provide a clean portable toilet service that is also reliable.
