After three consecutive 1-1 draws, and five matches without a win in all competitions, manager Gary Hackett made one change to the team, with Luke Benbow returning in place of Josh Quaynor.
A goal-less first half saw Curzon have slightly more of the play but with Stourbridge creating some chances of their own. Benbow saw a shot saved, and Chris Knight fired over late in the half, although Coleman was the busier of the two keepers.
However, Curzon began the second half with a bang and were ahead within 60 seconds. Niall Cummins picked out Alex Brown and his low shot gave Coleman no chance.
The home side went on to dominate proceedings from that point, but it took until the 74th minute for them to consolidate their lead when Cummins himself nodded in Joe Guest's cross. And the match was put well and truly beyond Stourbridge's reach five minutes later when Matthew Warburton smashed home a third.
The defeat sees Stourbridge drop to 12th in the Premier Division table.
Stourbridge: Coleman, Richards, Brown, Williams (Smikle 54), Benbow (Morgan-Parker 64), Miles, Connolly, Broadhurst, Wint, Canavan (Fitzpatrick 60), Knight.
