SUBSTITUTE Michael Wilde crowned a commanding Chester performance with an injury time headed goal.
Blues boss, Neil Young, celebrating his 37th birthday, saw his side retain their unbeaten home record.
Chester broke the deadfock in the 24th minute when Liam Brownhill's well measured right byline cross found Matty McNeil whose header found the net off the underside of the bar.
Brownhill came close to doubling the Blues advantage in the 43rd minute after crafting a one-two with McNeil and seeing his 12 yard shot hit the base of the left post.
McNeil increased Chester's account in the 55th minute when he controlled a pass from Robbie Booth before creating space and stroking the ball home in to the bottom right corner of the net.
Luke Holden put Chester 3-0 up in the 89th minute when his angled lob beat the Matlock keeper and found the target off the underside of the bar.
And Wilde netted the Blues' fourth goal with a header from Iain Howard's cross three minutes into injury time..
