Lowerhouse closed to within 10 points of the top of the Lancashire League table after two weekend derby wins - including a tight tussle at neighbours Burnley on Sunday.
The West Enders thumped Colne by 155 runs at the Horsfield on Saturday, after amassing the highest innings total of the season to date, clocking up 269-7.
And on Sunday, they edged the main event by four wickets at Turf Moor to leave Burnley rooted to the bottom of the table, winless in the league after eight games.
At Colne, Charlie Cottam won the toss and elected to bat. After losing Jack Edgar for 20, Ben Heap (49) and Jonny Whitehead (21) shared 71 - with Heap passing a landmark of 3,000 Lancashire League runs along the way.
Further solid contributions from Matt Walker (37), Cottam (34 not out), Chris Bleazard (30) and professional Cobus Pienaar (26) were added to by 32 extras to put Lowerhouse well in control.
And in reply, Colne were soon in trouble at 65-4, before being dismissed for 114, as Pienaar claimed 5-38.
Pienaar was again among the wickets on Sunday as he recorded his league best of 6-22 from just 14 overs as Burnley were bowled out for 107 after winning the toss.
Daniel Pickup (16) and David Brown (19) put on 31 for the first wicket, but it was all downhill from there for the home side as Pienaar claimed his first victim, bowling Brown.
Burnley captain Bharat Tripathi followed at 43 in strange circumstances, run out by Joe Hawke after losing concentration, caught out of his ground after playing the ball back to the bowler.
Pickup was then trapped in front by Jon Finch on the same score, and when Steve Brunt followed suit to Hawke, Burnley were 46-4.
Professional Chris Holt shared 28 with Matt Tomlinson, but Pienaar bowled the youngster for five, and Holt fell to his opposite number for 29, to a diving catch at point by Paddy Martin.
Michael Kelly (12) played on off Pienaar at 94, and Jhangir Liaqat went lbw for the South African’s fifth wicket without scoring.
Pienaar bowled Paul Mortimer (2) at 97 before Matt Walker took a return catch to see off Cole Hayman (5).
Lowerhouse replied through Finch (14) and Heap (17), who put on 37 for the first wicket - and another five wickets fell for just 22 runs to put Burnley back in it.
Holt removed Finch and Whitehead (1), before Graham Lalor bowled Heap (17) and Walker, caught and bowled for no score.
And when Holt sent Joe Martin and Chris Bleazard back, both for one, Burnley sensed blood.
But Pienaar (42 not out) rounded off a superb weekend as he partnered Hawke (15 not out) to victory with a match-winning stand worth 53 to see Lowerhouse home in the 41st over.
The previous day, Burnley lost out by 48 runs at home to Nelson.
The visitors won the toss and batted, totalling 188-7, with number three batsman Toqir Hussain the mainstay of the innings with an unbeaten 84.
Captain Neil Thompson (26) and Lewis Bradley (25) also contributed, while Holt took 3-67.
Tripathi, also batting at three, led from the front in reply with a knock of 47, but found little in the way of support.
Opener Pickup made 19, Brunt 15 and Holt 13, as Harrison Phelan took 4-44.
• Lowerhouse CC have had to concede their LCB second round cup to Westhoughton due to a lack of dates on which to play the game.
