When choosing a cleaner, there a number of important factors that are needed to be considered
. Having sourced cleaners for many years we would say that the main factors to consider are as follows.
Having a cleaner who is established at cleaning in your area is one thing that you need to ensure. Some cleaners may not do a good job for you, especially when they are a new company because there is a tendency that they will turn out to be an unknown identity. You can ask questions about the work they have done in the area if they are an established domestic cleaning firm.
Linked to the above point we would always recommend you look for any customer feedback that is included on the cleaning firm's website. Also search for reviews of the cleaning firm on local business listing sites, where people can leave their reviews. This way you will be able to get a sense in advance as to which are the best companies and which aren't so good.
Make sure that the cleaners from the firm are fully vetted. References from their previous employers that they are good in their work is one thing that you should also check You would not want criminals coming into your house, that is why the firm should also have done a Criminal Bureau Record search of the cleaners to check that they do not have criminal history.
You may also want to ask to meet the actual cleaner who will be cleaning your house, particularly if you are going to be in the house when they are cleaning. So that you know you will feel comfortable with them around.
To see if you are happy to take them on longer term, you can always ask for at trial period or trial cleaning to assess the standards of the cleaners. You could ask them to do one cleaning job like kitchen cleaning and then see if you are happy with the outcome.
Lastly, you should always be able to make reasonable requests of your cleaner and you should remember that you are the customer at the end of the day.
