Recent Waterproofing reviews in NSW

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.

Shower walls waterproofing

$1,000

Budgewoi NSW 2262, Australia

18th Oct 2026

I've removed the shower walls in the bathroom in my home due to a leak, the floor is intact. It's 2 walls, approx 770 w on one side, 840 w on the other, 1800 h (I need to check this when I get back). My partner replaced the fibro and put silicone/ waterproofing on the top of it, but it's not sticking to the silicone properly. So I'd like someone to look at it, replace/ fix if necessary, and I understand it needs to have a compliance cert. Here's the photo to get an idea of the space and the floor/ hob that's left as is. Will get a photo of the fibro/ waterproofing in a the next day or two. If it's going to cost more to fix it than re-do the fibro then we are happy to do that. I have no idea what this should cost so just let me know- and if you do tiling as well please quote that too!
