Andrew Bulford’s 200th Dunston goal ensured the visitors would extend Billingham Synthonia’s winless run at home to five league games.
Bulford’s cross-shot gave Dunston the lead on 22 minutes.
Synners could have levelled just before halftime when they were awarded a penalty for a David Coulson. But Nathan Porritt could only blaze the penalty over the bar.
Synthonia pressed for an equaliser in the second half, however they were unable to conjure up enough chances.
Billingham Synthonia came into the game on the back of a 2-1 win at Durham City, while Dunston had beaten Guisborough 2-1 in the FA Vase.
Synners started the game brighter but after failing to create any serious threats on the Dunston goal it was the visitors who took the lead on 22 minutes Andrew Bulford’s cross-shot looped over goalkeeper Jonathan McDonald.
The home side had their chances to get back into the game, on 26 minutes Nathan Porritt attempted to find Michael Sweet with a through ball but the pass evaded the forward.
Sweet was again in the thick of the action on 33 minutes when his header from Kris Hughes’s cross forced a save from Liam Connell.
Synners big opportunity to get back into the game came on the stroke haltime when they were awarded a penalty for a David Coulson handball on the line. However Nathan Porritt sent his penalty over the bar and into the grass behind the goal. There were also arguments from the home crowd that Coulson should have received red for the hanball as the referee only showed the defender a yellow card.
Billingham Synthonia had the best of the second half chances with Michael Sweet missing perhaps the best of the half when he fired a near post shot straight at Connell following an exchange with Steven Huggins.
Nathan Porritt also had a decent chance near the end but he fired his strike over the bar when he had options around him.
Dunston could have doubled their lead in the second half. In the midst of Synthonia hammering their goal, Daniel Halliday sent a long-range effort wide. And at the death, Michael Dixon headed over from a corner.
Billingham Synthonia remain in the bottom three following defeat, they face a home game against Guisborough Town this coming Saturday.
