Can you regrout over old grout?
Not reliably; new grout needs depth to hold, so the old grout should be removed to a consistent depth before regrouting. A thin skim over existing grout tends to crack and flake off within months.

Grout usually cracks from movement or moisture: a flexing floor or wall, a missing caulk joint at corners and the tub edge, or water getting behind the tile. If the tiles also move when pressed, the backing may be failing and needs checking before regrouting.
Usually yes for small areas. EPA says that if the moldy area is less than about 10 square feet, most homeowners can handle the cleanup themselves. Larger growth or mold that returns after cleaning points to a moisture problem.

If several tiles are loose, the wall flexes, or there is mold spreading well beyond the grout lines, stop scrubbing. 24/7 Express Handyman Service can assess whether regrouting will hold or the wall needs more.
