League One play-off places as new boss Roberto Martinez secured his first home win.
The hosts had struggled to find a way past the relegation-threatened visitors before midfielder Andy Robinson converted a 75th-minute penalty.
Robinson turned provider when his corner set up defender Izzy Iriekpen to head in the second two minutes later.
Defender Dennis Lawrence hit the bar in the first-half while Paul Shaw fired over from close range for Chesterfield.
