The Tudors have earned just two points from their past four matches but those include draws against promotion rivals Chelmsford City and Havant & Waterlooville.
Hemel travel to in-form Welling United on Saturday, ten points behind leaders Dartford.
Whilst securing a play-off spot may be seen as the goal for some, Walker reckons his team can go on a run and gatecrash the title race.
The keeper told Hemel Today: “I think as a back unit this season we have it bang on but I think it would be unfair to blame the forwards for us not being top, I just put that down to us failing to win games that on paper we should have won.
“But I’m confident we are still in with a chance of nicking the title, I honestly believe that.
“Dean (Brennan, manager) and Stuart (Maynard, assistant) are a very solid management team and we know what they expect from us, and the one thing I can say is they are honest and will say what needs to be said in a professional manner.
“All dressing rooms can get very heated, it’s just the nature of football and it’s never personal.”
