Check the wall behind the wet wall
A shower surround can look perfect while the drywall behind it is soft. The reading, not the appearance, decides whether that section has to come out.
Bathrooms and kitchens produce more water than any other room, and they hide it best. Phoenix Mold Experts checks behind the surround, under the vanity base and inside the sink cabinet rather than treating the tile and calling it finished.
Surface growth on grout is a cleaning task. Growth on drywall, on a cabinet base or under a floor is a different job, because the material itself is wet and has been for a while.
In many Phoenix homes the bathroom fan either does not exist, is undersized or vents into the attic instead of outside. That single detail keeps a bathroom damp long after the shower is over.

How far it goes depends on what the moisture readings show behind the finishes. Phoenix Mold Experts explains that boundary before anything is removed.

Angle stops, supply connectors, reverse osmosis units and refrigerator lines fail slowly. The cabinet base is usually the first material to show it.
A fan that actually vents outside and runs long enough after a shower is the cheapest prevention in this climate. We will say if yours is the problem.
Some of these jobs end with a plumbing repair rather than a remediation. A dripping angle stop or a failed supply connector has to be corrected before a new cabinet goes in, or the same thing happens again.
If a drain line or a supply line under the slab is involved, the repair reaches further than the bathroom and the drying takes longer. That is worth knowing before the first quote is signed.

A caulk and grout cleanup is small. Removing a wet wall section, a vanity and part of a floor is not. Phoenix Mold Experts takes readings first so the quote reflects the actual wet area rather than a guess from the doorway.
If the growth is genuinely on the surface and the drywall behind it is dry, yes. Re-caulk once it is clean and dry. If the wall feels soft, the paint is bubbling or the smell persists, stop and get it looked at.
Because the material behind the finish is still wet, or the room never dries out between showers. A working vent fan that runs for a while afterwards solves a surprising number of these. See our prevention guide.
Removal and rebuilding are usually quoted separately. Phoenix Mold Experts will tell you what the remediation scope ends with so you know whether you still need a finish carpenter or a drywall crew afterwards.
