Second half goals from Ephron Mason-Clark and Shaq Coulthirst saw off a Shots side battling for their lives at the wrong end of the National League table.
Darren Currie’s men now haven’t conceded a goal for 379 minutes after another assured Bees defensive display saw off any Aldershot chances.
It was the visitors who had the first opportunity, Berkeley-Agyepong dragging an effort wide of the post.
Booty saw a shot go wide of the left post as Aldershot started the better of the two sides, but it wasn’t without Barnet pressure when Coulthirst had an effort saved by Mannion on the half hour.
Goddard saw his shot palmed around the post by Cousins shortly before the break.
The Bees took the lead almost instantly after the restart, Johnson crossing in and Mason-Clark heading home off the underside of the bar.
Aldershot did have the ball in the net soon after, but it was prodded home by Rendell who was adjudged to have been in an offside position at the far post.
Mason-Clark attempted to double his and Barnet’s lead but his flick was blocked on the line before former bee Mensah shot high and wide at the other end.
The Bees put the game beyond doubt with 5 to go, Coulthirst delightfully curling an effort high into the top right past Mannion.
