Direct answer
A basic patch may require several visits or drying stages even when the hands-on work is short. Backing and board are installed first, followed by tape and successive compound coats, sanding, texture, primer, and paint as applicable. Setting-type compounds can shorten some stages, but temperature, humidity, patch size, finish level, texture, and paint requirements still affect the schedule. A seamless result should not be rushed by trapping moisture under finish coats.
Ask for elapsed time as well as labor time, and confirm when the room can be used, cleaned, primed, and painted. If the opening was caused by a leak or electrical problem, repair the source and verify the assembly is dry and safe before closing it.
