Cracked, Missing and Discolored Grout Are Different Problems
A small missing section can often be repaired locally. Widespread cracking can indicate movement, while discoloration may be staining rather than material failure. The correct response depends on what the joint is actually doing.
Loose Tile Changes the Scope
Grout should not be used to lock down tile that has lost its bond. Hollow, loose or cracked tile should be evaluated under Shower Tile Installation & Repair or the general tile page.
Spot Repair and Full Regrout Have Different Visual Results
A local repair can look different from older surrounding grout because of age and staining. Larger regrouting can create more consistent color when many joints are deteriorated.
Caulk Belongs at Movement Transitions
Corners and changes of plane can require flexible sealant rather than hard grout. Caulking & Sealing covers that separate joint behavior.
Moisture Problems Must Be Separated From Grout Appearance
Recurring water damage behind tile or a failed shower assembly cannot be solved by regrouting the surface. The waterproofing condition should be addressed when symptoms point deeper than the joint.
For the broader service family around this task, Plumbing & Bathroom shows the parent scope and neighboring options without expanding this page beyond its purpose. A related project may belong under Tile Installation & Repair when that work becomes the primary need; keeping the scopes separate creates a clearer handoff from GROUT REPAIR.
FAQ

Only when the joint and tile are stable enough for a local repair.
