A Carl Pentney own goal broke the deadlock before a terrific solo strike from Jack Bridge gave the Clarets a healthy lead going into half-time.
The hosts sat off a little and were almost punished when Dave Tarpey hit the underside of the bar, but the Clarets were able to hook clear with their two goal cushion in-tact.
They failed to prevent Dean Inman from setting up a nervy half hour when he nodded home from inside the six-yard box, but Luke Daley rose off the bench to quell any worries when his shot hit the foot of the post before going in fifteen minutes from time, and Bridge added his second of the match four minutes later with a powerful finish from inside the box to make it 4-1.
The Mapgies ended the match with ten men after right-back Josh Huggins was shown a second yellow card in a game disrupted by bookings; no fewer than eight separate players were booked in a game that was played in the highest spirit.
The win leaves the Clarets five points above the drop-zone ahead of Tuesday night’s testing clash away at Hemel Hempstead.
The Clarets made one change to the side that came away emptyhanded from Truro last week with midfielder Harry Morgan, celebrating his 19th birthday, coming in for Lee Sawyer who dropped to the bench.
It was the hosts who were put under immediate pressure when top-scorer Jake Reid forced an early corner, but Bagasan Graham had the Clarets’ first chance and was unfortunate not to break the deadlock. Reece Prestedge’s punt up-field eventually found the feet of the winger who showed an excellent burst of pace from the half-way line before shooting into the side-netting from 14 yards.
It was an early warning sign for the Magpies as they began to let the hosts assert some authority on the match and put them on the back foot frequently.
Bricknell went closer still for the Clarets when a long Graham throw fell to him in the centre of the box, but his half-volley was equalled by Alan Massey with the Maidenhead skipper heading impressively off the line.
The Clarets were eventually rewarded on 23 minutes after Carl Pentney could do little when Josh Huggins hit the ball against the former City shot stopper. Sandro Semedo initiated the move before Graham drove at the Maidenhead defence, sliding it to Jack Bridge on the right. The Southend loanee jinked his way into the box before sending a cross-cum-shot that Pentney could only spill as it bounced into the net.
Bridge then produced a carbon-copy of that move five minutes later and the end product was telling; the ball nestling into the far bottom corner to double the Clarets’ lead and continue his impressive form.
The Clarets were guilty of sitting back a little after going two in front and had Dibble to thank when the ‘keeper rushed out to collect Dave Tarpey’s deft flick-on after Rory McAuley let him run through into the box.
Tarpey then went closer three minutes after the break when he hit the underside of the crossbar in what was an almost nightmare start for the Clarets who were beginning to lose their dominance in the match.
Their passing wasn’t as assured and clearances weren’t met with as much conviction, and they had looked to ride the storm until Dean Inman to head in a minute shy of the hour mark. A set-piece from the right was poorly dealt with by the Clarets, leaving the midfielder to nod home from close-range to halve the deficit.
The ever-present Bridge looked to restore their comfortable lead with some drilled crosses into the area that needed only the slightest of touches, but the resilient Maidenhead back-line made routine clearances.
They could, however, do nothing to stop Luke Daley from regaining City’s two-goal advantage. The substitute picked the ball up from range, striking a shot that hit the foot of the post before going in. It was only his third goal of the season, but a crucial goal nonetheless.
Bridge then sealed the win 11 minutes from time when he arrowed a shot home from inside the box, his sixth goal in seven matches.
It was a promising display from the Clarets, taking away the first stages of the second-half, and the win pleased caretaker boss Kevin Maher, who has been able to guide Chelmsford to three wins in their last four.
He said: "Apart from the spell just after half-time where we conceded and were under some pressure for fifteen-odd minutes, we've had to weather that, and hopefully that's the sign of a good team, we've come out the other side and scored another two goals.
"We've got quality going forward and I know we can score goals. We were the cause of our own downfall after half-time, some sloppiness all-round, and we let them into the game with a free header from a set-piece again which is disappointing.
"But listen, we've scored four goals at home again [after the 4-1 win over Bishop's Stortford] and I'm delighted for the players. The attitude and commitment they've shown has been brilliant."
