I have spent $70 for credits to quote customers on cleaning (lowest rates, only one customer hired me; most don't view or reply, which makes me think Thumbtack is creating bots to seem successful), and have had phishers (think: Nigerian check scam) on this site. There is no convenient way to contact customer service to block scammers, either.
It seems no one replies and credits to quote similar jobs range from $2-14 - JUST TO QUOTE! Take your chances with another site.
Review about: Thumbtack Website.
Reason of review: Bad quality.
