Wrexham manager Kevin Wilkin told BBC Radio Wales:
"I'm delighted for the boys and delighted for everybody.
"It was a strong 1-0 victory if there can be such a thing. I'm pleased with the way the boys applied themselves to the game.
"Chester started the second half stronger than us and had a bit of a go but we finished strongly."
Chester manager Steve Burr told BBC Radio Merseyside:
"It was a poor game of football, but Wrexham adjusted to the conditions better than we did. I don't want it to sound like sour grapes, but we had to fight the pitch before you could get the ball under control.
"Sometimes it happens. There will be a few more of these surfaces before the end of the season - where it's dry and hard. "It was the same for them as well though.
"They got that break, but Andy Coughlin made the best save of the game when Ollie McBurnie got on the end of a cross. The save was more instinct than anything else. A terrific stop."
