at (one's) doorstep(redirected from at his door step)
at (one's) doorstep
1. Literally, outside one's door. I'm at your doorstep right now—where are you?
2. By extension, one's responsibility. That issue is at the police commissioner's doorstep now. I always hire reputable contractors for my company because I don't want complaints of shoddy construction at my doorstep.
