Glad you got some justice @Jacob Szeto ! I know it can be very difficult to recoup your funds even when you win the judgement, unless they have a current bond. Were you able to actually collect the $9200 the judge awarded?
Make sure your contractor's bond and insurance are active throughout your relationship. I've had situations where they were current at the start of a project, and it lapsed part way through, causing issues even after the project was over.
If you work in Oregon, check out the CCB's naughty list of contractors with a history of complaints. http://www.oregon.gov/CCB/Pages/buyer-beware.aspx
You can also search specific contractors and see their history, insurance status and complaints: https://www.ccb.state.or.us/search/
If you have a residential developer's license, (which highly recommend if you are flipping homes in Oregon), you can set up a watch list of all your contractors and get alerts if their insurance or license lapses. https://portal.ccb.state.or.us/Modules/eWatch/
@Mathew Wray, I'll second your echo for Ambience Remodeling, Daniel is a worked for a number of our RareBird Investor Network members and they all have great things to say about him!
