Zak and Alex from Mad Hatter cleaned my dryer vent this morning and I am very pleased with the service I received. They arrived on time, despite traffic issues that they encountered. When they thought they were going to be late, they had the office manager call me, which was quite courteous. They worked quickly and were finished within an hour. They were friendly and mannerly. Such a nice change to experience good service in Atlanta! I highly recommend these guys.
