A scope that says very little
Terms such as clean offices or maintain floors are not specific enough. The agreement should identify rooms, tasks and frequency. Without that detail, expectations become a debate every time something is missed.
Unclear extras and price changes
Look for vague language around supply markups, emergency work, annual increases and periodic services. Ask for examples and require written approval before extra work is billed. A fair contract explains when pricing can change and how much notice you receive.
No clear exit or correction process
Long automatic renewals and narrow cancellation windows deserve attention. The contract should also explain how service issues are reported and how much time the cleaner has to correct them. Read these terms before the start date, not after the first problem.
Promises that are not written down
If the salesperson promises a dedicated supervisor, monthly floor work or free initial cleaning, make sure it appears in the final agreement. Friendly conversations are not a reliable service record. A clear contract protects both the customer and the cleaning company.
