Had a new customer call today.....6 weeks after we did the job for the first time.
Hello is that PurercleanYes it is, hello.
You flooded my hallI am sorry to hear that, How?
My front door leaks.Ok I will make a note to clean the door by hand next time.
Thats not good enough you should not have done it.I agree it should not have happened, but as its an external door we assume its weather tight.
Well you never cleaned the sills.I can assure you we always clean the sills, however if we missed some dirt I am sure we will get it on our second visit.
Well my car is old and the paint is not good. You got your water on it and I had to pay a man to polish it out, he said the chemicals in your water did it.We don't add chemicals, in fact our water is pretty much the same as rain water. Do you have problems when it rains?
Well my door leaked all down my hall.Would you like to cancel our services.
I don't know, when are you due.Why not call us when you need us next?
Ok Bye 
I have a feeling we wont be going back
