Glenn Poole was Brentford's match winner as they recorded their fourth straight victory with a 2-1 success over Chesterfield.
The Bees dominated the first half and were unfortunate to only go in level at the break but Poole scored the crucial goal just past the hour mark to give the hosts the win they deserved.
Chesterfield offered little in the first period but could have been ahead inside the first 20 seconds had Ben Hamer not dashed from his goal to smother at the feet of Jamie Ward as he raced clear.
And after that Brentford grabbed control of the game with Gary Smith bossing the midfield and leaving the visitors chasing shadows at times.
Alan Connell curled a free kick narrowly wide and Poole had a low shot saved by Barry Roche in the Chesterfield goal.
Connell had a header blocked and Smith forced a save from Roche when he raced onto a nice lay off from the Brentford striker.
And from the resulting corner Ryan Dickson and Poole almost recreated the goal the latter scored against Wycombe Wanderers on Boxing Day but Roche was in the right place to save the 25 yard volley this time.
It seemed only a matter of time before The Bees edged ahead, Karleigh Osborne miss-hit a volley when well placed and minutes later the hosts got their goal.
Smith and Connell linked superbly in midfield before the latter sent the former free with a nice through ball; Smith picked his spot and lashed the ball under Roche and into the net.
Smith almost added a second when he shot over soon after and a first time effort from Connell sailed wide as Brentford dominated.
The Spireites had been limited to a Jack Lester effort blocked by Matthew Heywood and a Ward header which flew wide before they equalised against the run of play just before the break.
Derek Niven, who had been nullified by Smith and Kevin O'Connor to that point, found space to pick a pass which cut Brentford open and Lester bobbled the ball past Hamer and into the corner.
Brentford were rocked for a few minutes and Peter Leven fired wide soon after but Connell came close to restoring his side's lead before the break with a chip which landed just the wrong side of the post.
The visitors improved after the break, buoyed by being fortunately level at half time, and it led to a fine advert for League Two football in the second period.
Roche saved well from Connell, Ricky Shakes headed wide and Poole miss-hit a volley at one end and Leven forced a save from Hamer at the other before Osborne rolled a back pass inches wide of his goal with Hamer racing back towards his net.
The crucial moment came just past the hour, Brentford almost scored from a Dickson corner when O'Connor had a shot blocked and Shakes had an effort deflected wide and from the resulting set piece The Bees did score.
Roche dropped Dickson's corner and Niven reacted brilliantly to deflect Ross Montague's effort onto the crossbar, Shakes had two efforts blocked before Poole picked out the bottom corner with his effort from 18 yards.
Chesterfield responded well and pushed The Bees back, James Lowry curled an effort against a post and Ward shot over from 18 yards after a nice one-two with Lester.
Ward was proving to be the main threat for the visitors, he pulled an effort wide and Heywood blocked another effort superbly moments later.
The home side were being forced to hit The Spireites on the break but they were creating openings, Connell had a header saved and then forced Roche to tip over moments later.
Osborne fired over from a corner, Connell shot narrowly wide and Brentford thought they had a third when a short corner between Smith and Poole led to the central midfield man firing a shot in, it flicked Lee Thorpe and nestled in the net only to be ruled out as the striker was offside.
If the powerful striker had missed the ball it would probably have counted but it proved not to matter as The Bees continued their climb up the table under new boss Andy Scott.
