Before You Call: What to Have Ready

A little preparation helps every plumber give you a better, more accurate number.

Questions to Ask Every Plumber

Ask each plumber the same questions so their answers are easy to compare.

  1. Are you licensed in this state, and what is your license number?
  2. Do you carry liability insurance and workers’ compensation?
  3. Is this a quote or an estimate, and can the final price change?
  4. What is included, and what could cost extra?
  5. Will you pull the permit, and is it in the price?
  6. What warranty do you offer on parts and on labor?
  7. How long will the job take, and what is the payment schedule?
  8. Is there a service call fee, and is it credited if I hire you?

Red Flags to Watch For

Any one of these is a reason to slow down and ask more questions.

After You Choose a Plumber

  1. Verify the license with your state board: CSLB in California, ROC in Arizona or NSCB in Nevada.
  2. Confirm the scope, price and schedule in writing before work starts.
  3. Keep copies of the signed quote, permit paperwork and warranty.
  4. Do a walkthrough when the job is done and ask about anything unclear.
  5. Hold the final payment until you are satisfied the work matches the quote.

Plumbing Quote Checklist, Questions Answered.

What should I ask a plumber before hiring?

Ask about their license and insurance, whether the price is a quote or an estimate, what is included, who pulls permits, warranty terms, timeline and any service call fee. Asking everyone the same questions makes the answers easy to compare. Use the checklist above as a script.

Have a short description of the problem, photos or video, the age and model of any equipment, and your timing. Details like access to a crawlspace or attic help too. The more you share, the more accurate the written quote tends to be.

You can verify a license with the state board: the CSLB in California, the Registrar of Contractors in Arizona, or the State Contractors Board in Nevada. Ask for the license number on the quote and look it up before work begins.

Yes. A written quote protects both sides by spelling out scope, materials, price, warranty and timeline. If a plumber only gives a phone price, ask for it in writing. Our guide to what a plumbing quote should include explains each item.

Often, yes. Many plumbers charge a trip or service call fee, and some credit it toward the repair if you hire them. Ask upfront so it does not surprise you. You can read more in our plumber hourly rate guide.

Three is a solid baseline for most jobs. It shows you a range without overwhelming you. For major work, compare the repair method and scope as well as price. See how to compare plumbing quotes for details. You can then decide whether the extra detail is worth a higher total.
