The very first time we clean your house it will be what we consider a deep, thorough cleaning. Why? Well, we believe that the initial cleaning needs to be a more thorough cleaning so that we can get the level of cleanliness of your home to a level where we can, afterwards, systematically maintain it.
We also assume that the first time we go into a customer's home, we will face "surprises" - for example, more dust and more areas in need of "elbow grease" attention. This is also part of the reason why the initial cleaning rate is more than the subsequent visit rates.
