Steve Burr made it five wins from ten since taking charge with a scrappy, marginal victory over fellow relegation strugglers Dartford at Princes Park as Gareth Seddon's stunning strike just after the break proved to be the difference in a game that conjured up few chances.
Joe Heath replaced Ricky Bridge in the starting 11 and Nathan Turner took the place of the suspended Jason Jarrett following the dramatic 3-3 home draw with Nuneaton.
Alex Wall was the first player to try his luck early on for the hosts, but he dragged his effort across the face of goal. In front of the BT Sport cameras, neither team could muster up a shot on target in the first half.
It was the visitors who had the first golden opportunity in a tight game. The Dartford defence misjudged a floated cross, but Gareth Seddon could only manage to head over the bar from a few yards out with the net gaping.
Nevertheless, Seddon made amends a matter of minutes later.
A long ball forward from Andy Bond bounced awkwardly on a poor surface, allowing the Blues forward Seddon to swivel and fire an emphatic volley into the far corner.
This goal gave Steve Burr's men a new-found sense of belief, and the energy levels rose to take control of the match. Matty Taylor shot wide after creating room for himself, John Rooney weaved his way into a shooting area on the edge of the box – only to shoot beyond the far post, and the goalscorer Seddon nodded wide inside the final quarter of an hour.
Dartford did muster up a chance late on, but Aaron Chapman made a strong save from a Lee Noble shot through a crowd of players.
Chester hung on for a critical three points at Princes Park, moving six points clear of the relegation zone.
