A single cracked floor tile or a loose tile in the shower does not always mean the whole room needs to be redone. Many tile problems can be repaired by replacing just the damaged tiles, as long as the cause is understood and spare tile is available. But some tile damage is a symptom of something bigger underneath, such as a flexing floor, a cracked slab, or water getting behind a shower wall. This guide explains common tile problems, what causes them, how repairs are done, and when replacement makes more sense.
Common Tile Problems
Cracked tiles
A crack across one tile is often caused by a dropped object or a point impact. Cracks that run through several tiles in a line usually point to movement underneath, such as a crack in a concrete slab, a seam in the subfloor, or a floor that flexes between joists.
Chipped tiles
Chips along edges often come from lippage, where one tile edge sits higher than the next, or from impacts. Glazed ceramic shows the clay body under the chip; through-body porcelain hides chips better.
Hollow-sounding tiles
If tapping a tile with a coin or a screwdriver handle sounds hollow, the tile may not have had full mortar coverage, or the bond may have failed. Hollow tiles are more likely to crack under load. One hollow tile is not always a problem, but large areas of hollow tile may lead to cracking or loosening.
Loose or popped tiles
Tiles that rock or pop up may have lost their bond. In floors, this can come from poor installation, moisture, or expansion when there are no movement joints. A row of tiles tenting upward in the middle of a room is a classic sign of missing perimeter or field movement joints.
Loose wall tiles in showers
A loose tile in a shower is a warning sign. It often means water has gotten behind the tile, softening the backer or adhesive. Older showers with tile set directly on drywall or with failed waterproofing are especially prone to this.
Cracked or missing grout
Grout problems often appear before tile problems. See our grout repair and regrouting guide.
Finding the Cause First
A good repair starts by finding why the tile failed. An installer may:
- Tap the surrounding area to map hollow spots.
- Look for a pattern in the cracks, such as along a joist line or matching a slab crack.
- Check the floor for bounce.
- Look for moisture behind shower walls, sometimes with a moisture meter.
- Check whether perimeter movement joints exist.
- Look at the ceiling below a bathroom for water stains.
If the cause is ongoing, such as a flexing floor or a leaking shower, replacing tiles without fixing the cause usually means the new tiles fail too.
How a Tile Is Replaced
- Remove the grout around the damaged tile with a grout saw or oscillating tool to free it from neighboring tiles.
- Break out the tile carefully, working from the center so neighboring tiles are not damaged.
- Clean out old mortar down to the substrate so the new tile sits flush.
- Check the substrate and repair if damaged.
- Set the new tile in fresh mortar with full coverage, flush with neighboring tiles.
- Grout after the mortar cures, matching the existing grout as closely as possible.
- Seal if the grout or tile requires it.
Matching Replacement Tile
The biggest challenge in tile repair is finding a match. Tile colors vary between production lots, and many tiles are discontinued after a few years. Options include:
- Spare tiles left over from the original installation. Check the garage, basement and attic.
- The original manufacturer or supplier, if you know the brand and line.
- Tile salvage, using tiles removed from a hidden area, such as under a refrigerator or inside a closet, and replacing those with a close match.
- Accent or decorative inserts, turning a repair into an intentional design element.
- Replacing a defined area, such as a whole section bounded by thresholds or walls, so the change is less noticeable.
Grout color matching can also be tricky because old grout darkens and changes over time. A grout colorant or full regrout of the area can help even out the look.
When Replacement Makes More Sense Than Repair
- Cracks are widespread or keep spreading.
- Large areas of tile sound hollow.
- The shower has signs of leaking behind the tile, such as loose tiles, soft walls or stains below.
- The floor flexes and needs structural reinforcement.
- Replacement tile cannot be matched and the damaged area is in a highly visible place.
- The tile is old and you have been planning to update anyway.
In showers, replacing tiles over a failed waterproofing layer only delays the problem. If water is getting behind the tile, the shower usually needs to be rebuilt from the studs out. See shower tile installation.
Repair Considerations in Michigan Homes
Older homes around Clinton Township, Mount Clemens and Roseville often have tile installed directly over wood plank subfloors, or in mortar beds that have held up well for decades. Repairs in those floors need different methods than modern installations over cement board or membranes. In basements, cracks in tile often follow cracks in the slab caused by settling or frost movement near foundation walls. Crack-isolation membranes during repairs can help prevent recurrences when the slab crack is stable.
What Tile Repair Costs
Tile repair is usually priced by the job rather than per square foot, because a few tiles take nearly as much setup time as a small area. Angi lists tile labor at roughly $60 to $120 per hour when billed hourly, per its 2026 tile installation cost guide. Costs depend on:
- How many tiles need replacing.
- Whether you have spare matching tile.
- Accessibility, such as tiles under toilets or vanities.
- Whether the substrate needs repair.
- Grout matching or regrouting the surrounding area.
- Minimum trip charges many contractors have for small jobs.
These are general estimates, not quotes. A local installer will give you a written estimate after seeing the damage.
