I used thumbtack, given the guarantee (they don't honor it) and belief that the contractor I hired to replace my roof, who is still listed was licensed, insured and bonded. After all, thumbtack clearly stated that - and if there was a problem they would cover "damage to property" caused by one of their listed service providers. The "contractor was not licensed, stated he was insured by Thumbtack (they both misrepresented the coverage and never paid one cent); the contractor is convicted in 3 states on multiple fraud (felony and misdemeanor) in NC (as recently as 2020), NJ, FL, VA. Thumbtack lied about having an attorney (the last one left); lied to State of California Consumer Affairs (in writing) and Attorney General's Office. Beware. This listing service is in it to get money from contractors - to hell with consumers they burn or houses they ruin (due to negligent failure to tarp and pulled roof, use competent staff causing additional damage to walls, collapsed ceilings, ruined floors, electrical damage, and more)
