Most tile failures start under the tile. In the prep, the substrate, or the waterproofing. Here are the common problems, their causes, and the early sign to call a tiler. Catch it early and you skip a tear-out.
01.
A flexing subfloor, missing expansion joints, or tile set over an unstable base.
A hairline or split crack running through a tile, often in a line across a floor.
02.
Movement, the wrong grout, or joints that were not packed and tooled right.
Grout crumbling, powdering, or falling out along the joints.
03.
Poor thin-set coverage or a bond failure leaves tiles unsupported underneath.
A hollow tap-tone, or a tile that shifts or lifts underfoot.
04.
Rushed setting, an unflat base, or skipping leveling clips on big tile.
Tile edges sitting higher than their neighbors, catching a toe or the light.
05.
Failed or missing waterproofing lets shower water soak the wall or subfloor.
Loose tiles in a shower, a musty smell, or staining on the ceiling below.
06.
Unsealed grout absorbs water, soap, and mildew in wet areas.
Dark, blotchy, or moldy grout lines that will not scrub clean.
