Stuart Swift fired an early chance wide for the hosts, after Danny Murphy had done superbly to touch a deep cross from Steve Sinclair back to Dan Burnell, who in turn played it into the midfielder's path.
Chalfont St Peter, looking to do the double over Slough after beating the Rebels back in December, played some neat passing football early on, on an increasingly bumpy Holloways Park pitch, but Daniel Hughes fired well over after the visitors found him in space.
Whilst Slough had looked like they would carry the greater threat, the Rebels failed to get close enough to the Chalfont goal to get an effort on goal, and were punished with 19 minutes played as a low ball across the face of goal from the left was converted past James Warrington in the middle by Terrell Lewis.
The visitors went close again almost immediately after, with Slough skipper Dave Woozley down with a head injury, but fortunately the chance was spurned.
A Stuart Swift free kick, blasted into the Chalfont defensive wall, was the best Slough could offer as a frustrating first half drew to a close, and Steve Bateman’s side should have fallen further behind at the start of the second, but Hughes planted a free header straight into the arms of Warrington.
But better was to come from Slough, and, after Nathan Bowden-Haase failed squeeze a shot at goal from a corner kick, Burnell worked space for a shot which Mark Oliver pushed up and away to safety.
On 65 minutes, Slough’s greater urgency was rewarded. Steve Sinclair, who had a frustrating afternoon to this point, swung over a superb cross which Sean Sonner attacked with purpose and headed past Oliver to bring his side level.
Chalfont came agonisingly close to regaining the lead soon after – Hughes again a major threat, this time finding some space and blasting an effort towards the top corner. The ball appeared to be heading in, with Warrington beaten, but flew just past the post.
Slough started to turn up the heat as Jerome Anderson replaced Danny Murphy, but not before the latter had got himself into a good position, only to play a low ball across goal which Oliver was able to gather.
Anderson looked a real threat in the closing stages as Slough remained firmly on top, and the hosts put together a fine move which ended in Ollie Burgess volleying well wide. Chalfont then withstood a major goalmouth scramble as Slough pressed for a winner, but it was not to be and Slough will see this as a missed opportunity with top dogs St Neots also dropping home points.
