For example, think of two different carpet cleaning companies. The first cleaner is in and out in less than an hour and doesn't even vacuum. Then the second company carries out a thorough 9 step cleaning process, paying detail to each step. What's more, the second company guarantees their work.
So would you expect both companies to charge the same? Hardly!
Thats why you should ask questions and choose wisely before you decide which carpet cleaning company you are going to use.
