Plumbing problems can be disruptive, whether it is a dripping tap, a blocked drain, or a leak you cannot locate. Choosing a plumber is easier when you know what to ask and what to agree before work starts.

Describe the problem clearly

Note what you have noticed, when it began, and whether it happens all the time or only in certain conditions. If it is safe, take a photo or short video. Share what you have already tried, and avoid guessing at the cause.

If water is actively leaking, protect people and belongings first. If you know where the relevant shut-off valve is and can reach it safely, turn it off. For a serious leak or any immediate danger, contact the appropriate local emergency or utility service.

Check relevant experience and requirements

Ask whether the plumber has handled a similar issue and what the proposed inspection will involve. Where your area requires a licence, registration, insurance, or permit for the work, ask how those requirements will be met and check with the relevant local authority if you are unsure.

Ask for a clear estimate

Before agreeing, ask for the expected work and cost in writing where practical. Clarify:

  • What is included in the visit or call-out.
  • Whether labour, parts, and any additional charges are separate.
  • What could change the estimate once the problem is inspected.
  • How you will approve extra work before it goes ahead.
  • Whether any guarantee applies, and what its terms cover.

Compare estimates on scope as well as price. A lower figure may not include the same checks, materials, or follow-up.

Agree on access, timing, and cleanup

Confirm when the plumber expects to arrive, which areas need access, and whether water needs to be turned off. Move fragile items away from the work area. Before the worker leaves, ask what was repaired, whether anything needs attention later, and how to contact them about the completed work.

Watch for warning signs

Be cautious if someone will not explain the proposed work, pressures you to approve an unclear price immediately, or starts extra work without your agreement. Ask for clarification and take time to decide. You can pause the job if the scope or cost is different from what you approved.

Licensing, insurance, permits, and consumer protections vary by location. Check the rules that apply where you live, and use a qualified professional for work that you are not trained or equipped to do safely.
