Leak Repair by Hills Emergency Plumber


Moisture entering through the wall and floor separations caused this shower leak. It had a movement crack along a grout line leading through the shower and across the bathroom floor towards the door.

The shower unit was successfully resealed using our superior standard seal solution, and the floor re-grouted and sealed for a perfect watertight finish.
