Hessey joined Chester after the club were promoted back to the Football League in 2004 and was a first-choice player for much of his first three years at the club, although he quite often missed games because of injury and suspension problems. The most notable was a five-match ban at the start of the 2006–07 season after an incident in the home game against the previous season.

He scored twice at Chester; once in a Football League Trophy tie against Rochdale and once in a league match against Rushden & Diamonds.
