We were looking at getting new hardwood floors and tried to use thumbtack to get quotes. The first contractor showed up, looked around and left stating he will send the quote. Never heard back from him.
The second one was more communicative, promised us the sun and moon and kept pushing us to sign the contract. We got suspicious and contacted the BBB. Turns out that he has had many businesses with different names before.He will get the advance from the customer and then vanish. His previous BBB rating was "F". I wonder how thumbtack that background checks all contractors missed on that.
Needless to say we went with a contractor who we knew even though he was a bit more expensive.
Consumers beware and do your homework before hiring someone off this site because thumbtack obviously doesn't.
