The hosts looked in real danger of collapsing as early as the opening four minutes, when first Warren Harris and then brother Scott gave Slough a two-goal lead – but recovered well and pulled one back soon after.
Warren Harris opened the scoring with just 72 seconds played, firing in on his left foot after Eddie Smith had nodded down a free kick into the six yard box.
Two minutes later, Scott doubled the lead, capitalising on a deflected pass from his brother as he drilled low past Paul Agu and into the bottom corner.
North Greenford rallied and had their best spell of the game, during which they pulled a goal back – Anthony O'Connor firing across Jake Somerville and in, with a quarter of an hour played. Moments before, the Slough goalkeeper was required to rush out and tackle one of the home side's strikers.
O'Connor saw another shot blocked soon after, but Slough soon got back into their stride and went close to extending their lead on numerous occasions. Scott Harris laid the ball off for Jamie McClurg to fire wide from the edge of the box, whilst Warren had an effort chalked off for offside.
Slough continued to pepper the hosts' goal, Agu denying Smith one-on-one, and Dan Sintim, playing a holding midfield role, heading a corner from debutant James Dobson straight at Agu. Dave Woozley also got his head to another of Dobson's corner kicks, but sent his effort just over, and Scott Harris lobbed just wide.
In truth, it was a mystery how Slough had only taken a 2-1 lead into the half time interval, and the Rebels had a nervy moment as Somerville fumbled a long shot from Danny Johnson early in the second half, and O'Conner had a strike deflected behind for a corner.
Whilst the hosts looked a threat in attack, they were increasingly susceptible at the back, and soon after Warren Harris had volleyed a chance just wide, he headed a cross from Dobson back into the six yard box for his brother Scott to nod it past Agu with 55 minutes played.
Four minutes later, Michael Dart hacked down Smith in the penalty area and Smith handed Scott Harris the ball for him to claim his third goal of the evening from twelve yards.
From then on, it became a case of damage limitation for the hosts, but Slough were awarded another penalty as Adam Cornell, who replaced Scott Harris immediately after the fourth goal, was adjudged to have been tripped by Agu. However the goalkeeper made amends as he dived to his right to keep out Sean Fraser's spot kick attempt, also blocking the follow-up from Dobson bravely.
Cornell got his name on the scoresheet to make it 5-1 with twelve minutes remaining, turning the ball in after Smith's deflected shot had rebounded back off the crossbar.
Then Smith, who had done everything but score, plundered two goals in the final eight minutes as Slough got in behind the North Greenford defence at will. First, he ran on to a through pass from substitute Gareth Risbridger and slotted the ball between Agu's legs – and two minutes from time, he chested down a cross from Jake Parsons and finished with ease to round off the scoring for a ruthless Slough side.
