"I requested a quote from five companies, two of which responded. Drain Pro Services was the second to respond and the representative offered a flat fee for the service for Angie's List members. The representative indicated that he could be to my house in thirty minutes. I accepted and, indeed, the representative (Rep) arrived within thirty minutes. He was there for over two hours clearing my drain. He completed the job and we are very happy with his work."
