The Amount Of Work
The amount of work required to keep a house clean is very different if you have a modest, well kept home versus a group of college students trying to get their security deposit back at the end of the year. There are many different things that will be considered when the cleaning lady sets the cost of cleaning your home. Some of them may seem a little strange, but in the end, they all add up to either more or less work for the person doing the cleaning.
The square footage of the house and the numbers of rooms will also be essential because larger houses are harder to clean fast and takes more work and time. If not all the rooms are to be cleaned, that will also be taken into consideration for your estimate. If you know this before contacting them be sure to mention and it will be simpler to give you an exact estimate.
