Adam is a fantastic communicator and incredible efficient. He is punctual, true to his word and an expert at what he does. He’s also very trustworthy and honest. I had major leaking issues in my shower which affected the adjoining wall and he pulled back the tiles, removed all cement and waterproofed the area, added original tiles and grouted the area as well as waterproofing the walls of the shower with spray.

Bathroom Waterproofing Repair

$500

Lindfield NSW, Australia

1st Jul 2025

I’m looking to get a quote for a waterproofing repair in the bathroom of my apartment in Lidfield. The building is about 8 years old. Recently, I’ve noticed that water is leaking through the floor after showers — it appears that the waterproofing around the floor waste (drain) has started to deteriorate. Water is seeping underneath the tiles and pooling near the bathroom door, eventually reaching the carpet in the adjacent bedroom. Could you please let me know if you’re available to inspect and provide a quote? Feel free to let me know what information you may need in advance.

Waterproof en-suite shower drain on second level of semi

$139

North Bondi NSW, Australia

18th May 2025

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.
