Quality Equipment & Quality Service

Customer satisfaction and exceeding your expectation is our most important priority.  We are always available to assist you and provide 24 hour service.  Our office staff and uniformed drivers  and service workers treat everyone with respect.

STWS is the only portable toilet rental company in Laredo to be Health and Safety Certified by the Portable Sanitation Association International.  We have an ongoing Employee Safety Training program and our drivers and service workers will always get to your job site, special event site or your home wearing STWS uniforms, safety gear and company identification for your peace of mind.

STWS performs quality assurance on a daily basis. If we are unable to service a unit because of a locked gate, mechanical difficulty, a muddy jobsite or blocked access, we will contact your office the same day to reschedule or make other arrangements.

We have the best available equipment, clean, highly maintained and serviced with the right units to meet your requirements including special rental units used only for special events.  We always use environmentally safe chemicals.

Another quality service is our Damage Waiver program. Available for just pennies a day, you have the choice to pay a bit more and be relieved of the risk of back charges for accidental damage, vandalism, destruction by fire, theft, etc. for the equipment you have rented.
