Wealdstone head to Farnborough for their next pre-season friendly on Saturday having won their first two outings.
They faced Bracknell Town at Rayners Lane last weekend and new signing Tahvon Campbell - having joined on a season-long loan from National League rivals Rochdale - had early sights of goal.
The Robins opened the scoring, but Stuart Maynard's men levelled just before half-time through Campbell.
Bracknell regained the lead after the restart, following a raft of changes, but Giovanni McGregor played in Tarryn Allarakhia to fire a superb shot into the top corner of the net from the edge of the box to make it 2-2.
Olufela Olomola played Allarakhia through moments later but he was denied by a great save by the visiting keeper, who produced another smart stop to thwart the winger.
Having used six trialists on the day, Wealdstone found an injury-time winner when a corner was played to Corie Andrews and he found Jaydn Mundle-Smith to slot home.
Stones welcomed League Two outfit MK Dons to Grosvenor Vale on Tuesday and saw Ashley Charles and Micah Obiero go close in a frantic opening, while Jonathan Leko and Mo Eisa - who hit a post - had chances for the visitors.Max Kretzschmar cleared a Jack Tucker header off the line midway through the first half, with Stones opening the scoring on 26 minutes when Obiero knocked a Charles Clayden cross into the path of Alex Dyer to smash home from 12 yards.
Eight changes were made at half-time, with five trialists brought on, and more substitutions were made - 10 by MK Dons and a further three by the hosts - midway through the second half.
The visitors levelled when Darragh Burns chipped the ball over Wealdstone's defence for Max Dean to net with a superb volley on the turn and they went close to a second goal on 84 minutes when Zak Jules fired into the side netting.
But Stones countered to secure a 2-1 victory as Olomola collected a deep cross and squared to McGregor who made no mistake.
*Harrow Borough slipped to a 1-0 defeat at Haringey Borough in their first pre-season friendly on Saturday.
But they bounced back to beat Ware 3-1 in midweek and visit AFC Dunstable for a behind-closed-doors fixture this weekend, before facing North Greenford United at Brunel University Sports Centre on Tuesday.
Southern League fixtures are to be released on Friday at midday.
