Former Maidstone manager Harry Wheeler won on his return to the Gallagher with St Albans. Wheeler - head coach under Jon Meakes at the Hertfordshire club - saw his side run out 2-1 winners.
Victory moved them above the Stones into the National League South play-off places while the hosts, who had George Fowler sent off at a goal down, slip to eighth.
Shaun Jeffers and Gio Rasulo put the visitors in charge, with Matt Rush pulling a goal back. Paul Appiah - he made his debut in the reverse fixture - and Lamar Reynolds came into starting XI as George Elokobi made two changes from the midweek draw against Bath.
Raphe Brown and Bivesh Gurung dropped to the bench. Maidstone had a decent chance in just the second minute when Reiss Greenidge lost his man from a Sam Corne free-kick but Michael Johnson made the save.
