At first Home Advisor would not give me the names of the professionals they wanted to just send someone out. I need to talk to the professional and ask questions. I always get three estimates and that has saved me a lot over the years. The Home Advisors guaranteed price was way to low. Even I saw that and after 3 estimates it was apparent. If I can't get access to the list of professionals then I will simply go to the phone book/on line. We have used Home Advisors for years with good results but we went off their list of pros and chose the best fit.
