Michael knows his stuff. Will recommend

Outdoor Wall Waterproofing+Fixing ground gutter

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.
