Grout cleaning and regrouting involves removing stained, crumbling, or failing grout from between tiles and applying fresh grout to restore appearance and waterproof function.
In practice
You'd see this when a property manager is turning over a rental and the bathroom grout is black with mold.
Why it matters
Grout regrouting is significantly less expensive than full retiling.
Common questions
How do I know if grout needs cleaning or full replacement?+
If grout is discolored but intact, cleaning and sealing may suffice. If it's crumbling, full regrouting is needed.
Is it possible to regrout without retiling?+
Yes — the old grout is removed carefully and new grout is applied over the existing tile.
