I started this discussion here because, i think everyone looking for this In London many agency providing a cleaning services at doorstep, they all say they are professional, reliable and above all cheap. Before hiring a cleaning services we must check all the details about the company, this can be done through website, from friends those who are having prior experience. Things keep in mind while choosing a company: Where do they live? If they live too far away they would probably be late most of the time, while selecting a candidate give importance to the nearest location, so whenever you require you can call and ask for services. Security and belief are also important. Is it secure to hand her your house keys? And are you sure she will not send her friend to clean on her behalf when she needs to be elsewhere? While contracting with the company makes sure about security. Do they have insurance? What if they break something valuable or set up the house on fire? Take an alternative option for some time you have dinner party or sometime they have some personal problem ask for alternative.
