A plumber cut my wall open. Who closes it back up?
Usually not the plumber. Most trades cut the access they need, make the repair and leave the opening, because closing and finishing drywall is a different trade. That is the job we get called for most often, and it is worth doing once the pipe has been tested rather than immediately.
Check two things before it closes
That the repair has been run and tested under pressure, and that the cavity is dry. Closing over a joint that has not been proven means opening the same hole again.
While it is open, look at what else is in there. Wet or compressed insulation should be replaced rather than covered, and this is the cheapest moment to add a shutoff, run a wire or fit an access panel if one would help later.
Closing it properly
Backing gets added behind the opening so the patch has something to fasten to. New board is cut to fit tight, screwed off, taped and finished in coats rather than filled in one pass.
Then it is texture matched to the surrounding surface and primed, so the paint that goes over it does not flash a different sheen where the compound is.
The part people underestimate
Texture is what decides whether the repair disappears. On a ceiling especially, a patch that is flat and correctly sized can still show if the texture is close but not right.
Where a match will not hold up in that light, carrying the finish to the corner or across the whole ceiling reads better than a visible rectangle.
