10 Essential Questions to Ask Before Hiring a Plumber in 2026

Protect Yourself Before Signing or Authorizing Work

Hiring a contractor can feel overwhelming, especially during a stressful plumbing emergency. However, taking three minutes to ask the right qualifying questions will protect your pocketbook and guarantee quality workmanship. Keep this 10-question checklist handy before authorizing any plumbing job.

The 10 Crucial Questions:

1. "Are you licensed in this state and can you provide your license number?"
   Verify the number immediately online with your state's contractor licensing portal to confirm it is active and in good standing.
2. "Do you carry full general liability and workers' compensation insurance?"
   Never allow a contractor on your roof or under your crawlspace without confirming workers' comp coverage.
3. "Do you bill by the hour or flat-rate upfront pricing?"
   Flat-rate pricing is vastly superior for homeowners because you know the exact total cost upfront, regardless of how long the repair takes.
4. "Is an inspection or diagnostic fee charged, and is it waived if you perform the repair?"
   Most reputable plumbers waive their standard diagnostic fee if you hire them to complete the recommended service.
5. "Who will physically be performing the work on-site?"
   Confirm whether the person quoting the job is doing the work or if an apprentice will be dispatched.
6. "Does this job require a municipal permit, and will you pull it?"
   Legitimate contractors always pull required permits for water heaters, repipes, and sewer lines.
7. "What warranty do you provide on parts and labor?"
   Look for at least a 1-year workmanship warranty on new installations, plus manufacturer parts coverage.
8. "Do you offer 24/7 emergency dispatch if this issue recurs tonight?"
   Ensure you have a direct emergency callback number like (833) 997-7008.
9. "Will clean-up and disposal of old fixtures/pipes be included?"
   Confirm that old water heaters or broken cast iron pipes won't be left on your curb.
10. "Can you provide recent references or online reviews from my immediate area?"
    Check local customer feedback across independent review platforms.
