Four weeks is not a calendar month
A 28-day rental renews every four weeks. Ask for the next charge date and ongoing rate in writing. A first-period amount may include delivery, while later periods may not; a removal fee can still remain due at the end.
An estimated finish date is not a pickup request
For an open-ended rental, contact the rental team when the unit is no longer needed. Confirm the required notice, whether billing stops on request or collection, and how a partial final cycle is treated.
Review the service plan when use changes
More workers, extra shifts, or new site access restrictions can change what the restroom needs. Check the weekly schedule, supply replenishment, and additional-visit charges with the rental team.
Longer-term pricing needs a written answer
Request an itemized quote for the expected project duration. Confirm the renewal rate, service schedule and any longer-term pricing offered, including whether the price changes if the project ends sooner.
