Michael knows his stuff. Will recommend

Outdoor Wall Waterproofing+Fixing ground gutter

$500

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.

Catherine Field NSW 2557, Australia

Edit: Pending - thanks everyone for their offers… currently engaging warranty team for builder before having outside trades attend. Leak suspected in upstairs ensuite shower causing staining on bottom floor roof. Main bathroom shower also might have a leak as well so we want to have a dye test / check waterproofing levels for both showers. We would also like the pipes inspected as sometimes water comes up from the floor drain when washing hands in basin. Ensuite shower head constantly has slow drip if that can be fixed as well. We would like this done ASAP if possible or within the next few days as we want to stop any leaks before we have mould issues.
