Repair complexity
Fixture-level work is generally narrower than opening walls, replacing a branch, correcting venting, or tracing an intermittent leak.
Access and restoration
Plaster, tile, masonry, cabinetry, finished ceilings, and tight chases add protection and restoration steps.
System choices
Water-heater capacity, material compatibility, valve quality, drain condition, permit needs, and after-hours timing can all change cost.
Planning note
Ask for a written scope and site-specific quote. Any range discussed before diagnosis is educational, not an offer.
