What plumbers charge for this job
Most of the price of a plumbing job is labor. Licensed plumbers in the U.S. typically charge $45 to $150 per hour, and many add a $50 to $200 service call fee that often covers the first hour. Expect evening, weekend and holiday visits to cost noticeably more; emergency hourly rates commonly run $150 to $350. Master plumbers and plumbers in high-cost metro areas sit at the top of these ranges.
Before work starts, ask whether the quote is a flat price for the whole job or an hourly estimate, and whether parts, permits and haul-away are included. See Plumber rates per hour and Emergency plumber cost for the full breakdown.
