A Northcliff homeowner had their bathroom tiled by a general handyman three years earlier. The tiles looked great initially. But the waterproofing was skipped. The grout was mixed wrong — too much water, too little adhesive. Within two years, grout lines were crumbling, tiles were hollow-sounding, and moisture was seeping behind the wall tiles into the brickwork.
We stripped it back to bare wall, applied proper waterproofing membrane to all wet areas, and retiled with quality adhesive and epoxy grout. Three years later — still perfect. The lesson: good tiling starts behind the tile, not on the surface.
