A plastic drain valve that clogs or won't reseal sometimes has to be replaced during the service.

It looks simple on paper, but shut-off valves that won't close, live circuits, and damage hidden behind the wall are what turn a 30-minute job into a much bigger repair bill. At this price point a pro visit is usually cheap enough that most homeowners just book it and move on.
Most homeowners in this range end up hiring out: the price is fixed before work starts, and the pro who does the job stands behind it.
