First Class Green Cleaning has been doing work for us for a very long time. We are very pleased with the work that they do and will continue using them for a long time to come. We have known the technician for a very long time as well and he does a really great job! He is a very nice man. I guess the cost of the service is normal. It certainly seems fair for the good work that we have always received. We have always recommended First Class Green Cleaning to people.
