Find trusted waterproofing contractors in North Bondi

I need my en-suite shower drain waterproofed. The en-suite is on the second level of a semi and there is a small drip going to the ground level roof. I’ve run some tests and know the waterproofing issue is occurring in the shower strip drain of the en-suite above (by using a bucket and pouring water only into the drain strip insert). I don’t think it’s the pipe in the drain. The metal drain insert also seems loose when pressing on it. Attached are photos incl. the space between the downstairs ceiling and the above en-suite floor where the drip can be seen (taken by putting phone through recessed lighting on ground floor). It looks like the prior owners have previously done a dodgy job of trying to waterproof from ground floor using silicon so I am looking to get this fixed properly. Would like this fixed on a Wednesday, Thursday, Saturday or Sunday. Flexible with time of day. Thanks Rory Update: Unfortunately I don’t have any spare tiles, if tiles need be taken up and replaced.
