All three goals were scored late in the second half, with Houston's 76th minute own goal extending Wealdstone's advantage after the home side had taken the lead in the 65th minute.
Junior Haynes replied for Slough on 86 minutes, but Wealdstone hung on to notch their fourth league win in five games — as Slough remained stuck at the wrong end of the table with just four points from a possible eighteen. Ex-Slough favourite Bryan Hammatt and former Wycombe and Windsor striker Dennis Greene helped the home side to three points after an even first half in which chances were few and far between.
Waeldstone's Vinny Somers and Slough's Paul Coombs went close in the first period, but one of the main talking points of the opening 45 minutes was the fussy referee, who booked six players before the break.
Just before the interval, Greene almost gave the home side the lead, but it was the visitors who went closest to breaking the deadlock early in the second half, when Coombs turned his marker only to see his effort cannon back off the post. Soon after Coombs went close again but, just as Slough were getting on top, disaster struck. Keeper Steve Mautone collected the ball out wide, but dallied on the ball and his rushed clearance was charged down by Danny Tilbury. The ball fell kindly to Lee Walker with Mautone stranded. Under pressure, he mishit his shot but it was good enough to beat Houston on the line.
The home side secured victory with a second goal 10 minutes later. Walker's effort was going wide when Houston stuck out a foot, under pressure from Somers, and the ball found corner of the net.
Slough's late consolation saw Haynes volley in Darron Wilkinson's cross. The result gave Slough manager Steve Browne his 40th defeat in 78 matches charge of the Rebels.
This, on top of a dismal FA Cup and Trophy record, compares none too well against the statistics of Slough's three previous managers.
Brian McDermott lost 35 of his 99 league matches in charge and reached the semifinal of the Trophy in 1998.
Paul Hardyman lost four of his 12 matches while Graham Roberts suffered defeats in 14 of his 42 league games as boss.
