  • It's always best to shop for a new plumber before your kitchen sink turns into Niagara Falls. Waiting never makes a plumbing problem better.

  • Get a firm estimate in writing. Make sure you're apprised of any problems that arise.

  • Multiple factors affect cost: fixture quality, quantity, job time, location and when you need the job done. Holidays, weekends and after-hours emergencies cost more.

  • Be aware of first-hour and trip fees. Most plumbers and rooting companies charge upfront fees or higher rates for the first hour just for showing up, though those fees usually can roll into the cost of repairs and renovations.

  • Going for the lowest bids can be problematic. Some companies offer lower hourly rates, but then tack on equipment fees and other extras you might not have anticipated.

  • Not all companies employ licensed plumbers. If the job is a simple root-out-the-clog, that might be okay, but licensed plumbers are almost always better at diagnosing tricky problems. Expect them to bring micro-cameras and other fun gadgets, and to warranty their work.
