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.

There was water damage mark on bathroom ceiling in the apartment below. Strata organized plumber to investigate and advised it might be tiles, grout, and sealants failure and suggested the owner to carry out the installation of a new seal over the top of the existing wall and floor tiles located within the bathroom first. The owner wanted to find out what exactly the source of leak is, it is because of Structural waterproofing membranes failure or tiles, grout, and sealants failure. And the owner wanted to get the second quote of water proofing works.
