Alex Reid hit his third goal in four appearances for Wrexham and it was enough to decide the outcome in a typically close affair with the north London side.
A first start of the season for Leo Smith, while Chris Dunn was able to take his place on the bench.
The first chance of the afternoon fell to the home side, as a half cleared free kick was
From a Wrexham corner on three minutes, Boreham Wood broke quickly up field and Akil Wright found himself marking three forwards.
He raced across to cover Kane Smith and delayed the pass just long enough, to slow down the other two attackers in their stride, so when the pass did come, the final effort by Angelo Balanta was hurried and turned away by Chrstian Dibble to safety.
Wedgbury was booked for something that happened as the players raced back, although it was not immediately obvious what his offence was.
There was also a booking for Leo Smith on six minutes, as he brought down Kane Smith in the home half of the pitch with a high challenge.
With 10 minutes on the clock, a Paul Rutherford cross was met by the head of Alex Reid, who directed his header towards the corner of the home goal, but keeper Grant Smith was able to get across and palm the ball away for a corner.
Just after quarter of an hour and Bruno Anrade raced through a gap in the Wrexham back line, he was bearing down on the Christian Dibble from the left channel, but his final shot was high and wide of the mark.
Shortly afterwards former Wrexham trialist Ricky Shakes also found space in the same area and his driven cross was not far from the advancing Anrade, who threw himself at the ball as it flashed across the face of the goal.
The Reds opened up the home defence on 27 minutes, when Ntumba Massanka and Alex Reid combined to pass the ball through the Wood rear guard. Reid might have been better passing straight back to Tums, but he drove to the line, although his cross was deflected away from the two yellow shirts in front of goal.
His next cross, three minutes later, was met by Tums, who stretched well to get his head to the ball and force another flying save out of the home keeper.
Just as the board went up for two added minutes, the home side were through again, but Angelo Balanta, screwed his effort well off target.
The home side started the half in lively mood and Shakes forced a good block out of Dibble in the opening minutes.
A clearing header by Leo Smith down the left wing, saw Reid spin away from his marker Mark Ricketts, but the home captain tripped the Wrexham striker and was booked.
On 59 minutes, the limping Leo Smith was replaced by Marcus Kelly.
Kelly's first touch was to win a corner and when it was delivered into the six-yard box by Rutherford, Alex Reid rose highest to head home and give the diving keeper no chance. All in front of the happy travelling fans!
On 65 minutes, Scott Boden was on for Tums and shortly afterwards Shaun Jeffers replaced Benson for Boreham Wood.
Following a Wrexham free kick, Manny Smith beat the offside trap, but his header, on the end of dropping ball Wedgbury passm was only into the hands of Grant Smith.
A Kelly flick header after 72 minutes was aimed towards Reid, but it took a nasty bounce and allowed defender Ricketts to clear for a throw in, close to his own goal line.
The home side had yet another free kick close to the half way line, which they sent long into the Wrexham box. It was headed clear, but the follow up effort was fired wide by Balanta from 20-yards out.
On their next attack, another Shakes cross from the left wing, was met by Anrade who had the time and space, but from 15-yards failed to test the Wrexham keeper.
Jeffers might consider himself lucky to only see yellow on 78 minutes, when he jumped into Pearson with his arm high.
Boreham Wood sent on another substitute with 83 minutes played, as Bradley Sach replaced Keiran Murtagh.
More good play by Kelly on 88 minutes, as his 50 yard cross field ball found Rutherford on the right and his early cross into the home box was met by the head of Reid, but guided his effort the wrong side of the back post on this occasion.
Dibbs was back on his feet after a knock, to take a low header on his line from Sach, as the Wood pushed forward.
As we entered five added minutes, another home free kick from the half way line was despatched by keeper Smith into the Wrexham box, but after the initial clearance, Anrade fired well off target.
The same player was much closer a minute later, as his looping header had to be caught by Dibble, with the Boreham Wood man landing heavily on the grass and taking time to get to his feet.
Another let off for the visitors, as Balanta’s effort hit Dibble on the line and then the follow up was fired high over the terraces by Sach.
This proved to be the final effort of an exciting game, one which was won by the Reds and lifted us into the top four of the league.
