We have been using The Cleaning Authority for several months now. It's been long enough where I feel confident in recommending them and the consistent quality of work they perform. Miriam is always so friendly and professional. While she can have a different person assisting her they follow her lead and exhibit the same attitude. Elizabeth for one is always up beat and friendly. They come when they say they are coming and perform the work they are assigned to do. I recommend providing some of your own cleaning products if you feel their eco-friendly ones don't quite get the job done.
