Bait and switch carpet cleaners will claim that the cost didn’t include high traffic areas. Or they may say it didn’t include certain needed chemicals. They may offer one room free and pick the smallest room in the house like a foyer or hallway to cover that free room.
When you go to hire a carpet cleaner you want to ask them plenty of questions. Pay close attention to their answers. Ask them about their specific certifications and licenses. Find out how long they have been in business. Ask for a list of references. Find out if the company screens their employees and what kind of training their employees undergo.
One way to avoid bait and switch is to hire a company that charges by the square foot. This way your quote is cut and dry. You won’t have any hidden fees pop up at the last minute. IT may seem more expensive to do it this way, but when this is the only charge you get you don’t have to worry about a bunch of add on charges.
