Lee, my sales man, was very patient and thorough with me. He took the time to answer my questions so I was fully aware of the service and why the cost of this process. The 2 men that cleaned under my house, sprayed it, layed the plastic down and set up my dehumidifier were very kind, respectful and knowledgeable too! Now I just need the electrician to get the process finished. And I am sure he will do a great job too!
