Containment and filtered air
Sheeting, sealed doorways and air scrubbers keep the work area separate from the rooms you are still using. Supply and return vents in the area are covered so the system does not move spores.
Removal is a controlled job, not a cleaning job. An independent provider should seal the work area, filter the air, take out the affected material, dry what stays and give you a record of what was done - after the water source has been dealt with.
Once material is disturbed, spores travel. That is the reason work areas are sealed off with plastic, put under negative pressure and filtered, and why the debris leaves the house bagged rather than swept.
In a single-story slab home with an open plan, containment matters even more, because one air handler serves the whole house and will happily spread whatever is released.

The exact list depends on the inspection. A provider should separate what has to happen from what is optional, and the quote should do the same.

Affected drywall, insulation, carpet pad and trim come out and are bagged. Framing and other materials that stay are cleaned rather than painted over.
Air movers and dehumidifiers run until the remaining materials read dry on a meter, not until a fixed number of days has passed.
Remediation and rebuilding are separate pieces of work. Taking out wet drywall and cleaning the cavity is one scope; hanging, taping, texturing and painting the new wall is another. Ask which one your quote covers so there is no gap at the end.
Ask for the finished record too: what was removed, what was cleaned, the drying readings and photographs. It is the only proof the job was done properly, and it matters if the property is sold or rented later.
If you are unsure what you are being quoted, compare removal and remediation. Start with a mold inspection if nothing has been measured yet, or see commercial work for a rental or business. The questions page covers the rest. Once the removal is finished and before a builder closes the walls, clearance testing confirms the area is dry and clean.
How much material has to come out, how hard the area is to reach and whether drying equipment has to run for several days. A bathroom wall and a whole wet hallway are different jobs. Ask the provider for a written quote after the inspection.
Usually yes for a contained area in one part of the home, as long as you keep out of the sealed zone. Larger jobs, or work in the only bathroom or kitchen, are easier if you can stay elsewhere. Ask the provider which one yours is.
Small contained areas are often a day of removal plus drying time. Larger jobs run longer, and drying is measured with a meter rather than promised to a schedule. Ask the provider for a realistic timeline once the wet area is mapped.
No. Surface products do not reach the material inside a wall, and spraying does nothing about the water that keeps it wet. Growth that returns after cleaning is a sign the source was never found. See signs of hidden mold.
Call and describe what you can see; ask the provider to put the removal scope in writing.
