The visitors had the ball into the net with their first chance. The ball was crossed in from the left and both Nathan Elder and Jamie Dormer challenged for the ball with it being bundled in toMichael Parkin's right, but the linesman had flagged for offside and the effort was ruled out.
Slough's first chance of the game brought a good save from Ricky Millard. The ball was delivered from the right wing by Mason and found its way through to Glen Harris but the midfielder was off balance as he hit his shot back across goal. It bounced up and would have crept in by the post but Millard intervened and turned the ball around the post.
Prolific striker Danny Hockton went close with a spectacular effort. Receiving the ball from Pat Sappleton, the striker controlled the ball on his chest and turned before firing a volley narrowly wide of the top corner.
Billericay continued to have the better of the chances. A Danny Kerrigan corner was headed goalwards by Elder and Hockton diverted the flight of the ball with his chest but Leon Woodruffe was on hand to head off the line.
Elder again went close forcing Parkin into a save before putting Billericay into the lead with four minutes of the half left. Contesting a through ball with Steve Daly, the forward touched the ball past the defender and ran through to convert low past Parkin.
It didn't take long from the start of the second half for the away side to extend their lead. Jamie Dormer was played in by a simple through ball and sidefooted in off the base of the post with just two minutes gone since the restart.
Slough did get the ball into the net as Andy Ballard ran onto to an unorthodox Ian Hodges pass. Glen Harris fed the ball in from the right, just behind Hodges. The striker threw his leg out behind him and flicked it forwards into the path of Ballard who finished from close but had been offside and the goal was disallowed.
Billericay did have a glorious chance to extend their lead as a shot came in from Hockton which Parkin palmed back out. It fell nicely for Elder, but the striker took an air shot and the Rebels escaped. The same striker was again presented with another excellent opportunity as a low cross shot from the right found its way through a crowd in the middle but as the striker slid in, again he did not make contact with the ball and the chance passed.
Whilst Slough battled hard, it was a lesser performance than they'd managed in the previous home game and even though up against a good side, will have felt they could have done better today.
