"It's been a long time since we've won at home and that's been a big part of our problem because the away form has been so good," said Richardson. "The response from the players was excellent, there was a lot of honesty and courage and now we have to build on this.
"Of all the travesties we have seen here at Saltergate that would have been the biggest if we had not won the game. I am very pleased because it was an excellent team performance. I can't think of anyone who didn't play really well."
There was also time late on for Derek Niven to make his first appearance since recovering from testicular cancer. He was given a great reception by the home supporters after coming on as an 87th-minute substitute.
Richardson added: "It was great to get him on and it was great to see him back."
