First question, have you turned the errant breaker switch all the way off before trying to reset? Assuming that you have done that, my next suspect would be a bad breaker switch.
If a new breaker trips immediately, I would next suspect that a wire in that circuit has become frayed and has made contact with another piece of metal during your renovation.
