I used Thumbtack to search for a contractor. They were all clearly cheaper than Home Advisor contractors so I hired one. I saw the guy throwing up one morning and asked if he was okay. He said he wasn't feeling good, i insisted the poor guy leave and come back tomorrow. GUESS WHAT... he never came back, left his tool bag here and my husband for a package of drugs in it. I was furious... I called Thumbtack to complain and ask how this guy was able to be referred by them and they told me anyone can sign up. YOU JUST SENT A JUNKIE TO MY HOUSE I SAID. They said they would look into it. End of story, the guy never came back took $1000 of my money probably spent $100 of it here and it's all my fault looking for these cheap quotes. HOME ADVISOR has real pro's thats for sure.
