Chapter 1 — What You’re
Solving
- Cracked grout: structural failure. Replace.
- Stained grout: surface only. Clean + reseal, not
replace.
- Missing grout chunks: leak risk. Replace.
- Discolored grout that won’t clean: replace for
cosmetic reasons.
- Grout separating from tile edges: tile or subfloor
movement. Replace and investigate.

stains, and separation from tile edges — the failure pattern that needs
