Hiring a plumber is a decision most people make under pressure — a leak, a blocked drain, or a hot water failure. But whether it's an emergency or a planned job, asking the right questions before you book helps you avoid surprises on price, scope and quality. Here's a practical checklist.
1. Are you licensed?
In Queensland, plumbing work must be carried out by a licensed plumber. Ask for their licence number and the licence class — a plumber may be licensed for plumbing, drainage, and/or gas fitting. For gas work, confirm they hold a gas fitting licence specifically. See our guide on the difference between a gas plumber and gas fitter
2. What experience do you have with this type of work?
Plumbing covers a wide range of work, from residential tap repairs to commercial installations. Ask whether the plumber has experience with your specific job — hot water systems, blocked drains, gas fitting, commercial work. Experience with the specific problem usually means a faster, more accurate diagnosis.
3. Can you provide a clear quote or estimate?
Ask whether the plumber provides a fixed quote or an hourly rate, and what the quote includes — labour, materials, callout fee, and any potential additional costs. For larger jobs, a written quote protects both parties. For emergency work, ask how the callout fee and after-hours rates are structured.
4. Do you guarantee your workmanship?
Ask whether the plumber guarantees their workmanship, and for how long. A workmanship guarantee means the plumber will return to fix any issues arising from the installation or repair. It's a sign of confidence in the quality of the work.
5. Are you insured?
A plumber should carry public liability insurance to cover any damage to your property during the work. Ask to confirm — it's a reasonable question and a professional plumber will have a ready answer.
6. Do you provide emergency services?
If you're hiring for a potential future emergency, ask whether the plumber offers emergency callouts and what their response time and after-hours rates are. Knowing who to call before an emergency occurs saves time and stress.
7. What materials will be used?
Ask what brand and quality of fixtures or materials will be used. Cheap components may fail early and cost more in the long run. A good plumber will explain the options and recommend quality products suited to your budget.
8. Will the work be compliant and certified?
For regulated work — gas fitting, drainage, hot water installation — the plumber should issue a compliance certificate confirming the work meets Australian standards. Ask whether this will be provided.
9. Do you have local references or reviews?
Ask whether the plumber has references or reviews from other Gold Coast customers. Local experience means they understand the area's housing stock, common plumbing issues, and council requirements. See our testimonials page for genuine customer feedback.
10. When can you attend?
For both planned and emergency work, ask when the plumber can attend and how long the job is likely to take. Clear scheduling helps you plan, and for emergencies, a prompt response is often the priority.
Why these questions matter
These questions aren't about being difficult — they're about making sure the plumber you hire is qualified, transparent, and able to do the job properly. A professional plumber will welcome these questions and answer them clearly. If a plumber is evasive about licensing, pricing, or guarantees, that's a warning sign.
