In order to ensure that they do a brilliant job all the time, reputable cleaning companies always provide on-going trainings for their staff. This is one thing you should always ask about, since you’ll want to make sure that you’re giving your hard-earned money to real professionals. Ask the cleaning company representative about how they screen and hire their employees, as well as the trainings and education they provide pre- and post-hiring. Ask them if their staff are knowledgeable about the best and most effective cleaning practices and methods (like in the case of carpet shampoo cleaning for example) and how well they handle the latest cleaning equipment. More importantly, ask how well do their employees deal with customers – you’ll want to work with courteous, polite, and responsible cleaners, always.
