Frequently Asked Questions

Q: Do plumbers work outside?

A: If the job requires outside access to plumbing fixtures, plumbers may work outside, as long as the work done is on the homeowner's property. For example, a clog in the sewer lines that connect to the city's sewer system may require the plumber to access the line through a riser pipe on the property away from the structure of the home. Some other jobs that involve outdoor plumbing work include:

  • Water line repair and replacement
  • Sewer line repair and replacement
  • Septic tank service, repair, or installation

Q: Do plumbers work on Sundays?

A: Plumbers do not typically work on Sundays, but some consider weekend hours to be part of their normal schedule. It's important to remember, if plumbing service is needed on a Sunday (or a Saturday in some cases), the bill may be higher because it's classified as emergency services. Unless the job is urgent, it may be best to wait until Monday.

Q: Do you pay plumbers upfront?

A: In order to factor in any unexpected costs or savings that weren't reflected in the initial estimate, most plumbers don't charge until the work is complete. A reputable plumber will provide an estimate in writing that serves as a good-faith summary of the costs involved with a job, but most won't actually require payment until the final calculations are complete.
