Photograph stains and note when the symptoms appear.

Questions to ask a Sydney plumber
- Which detection method suits this property?
- Is the quoted fee for detection only or also repair?
- How accurately can the source usually be located?
- Will findings and recommended repairs be documented?
Understanding the price
Plumbing costs can vary with travel, timing, access, fault-finding, materials and the extent of the repair. Ask whether the price is a fixed quote or an estimate, whether GST and call-out fees are included, and what circumstances could add to the final amount.
The cheapest initial figure is not always the lowest total cost. Compare the proposed method, inclusions, exclusions, licences, documentation and warranty as well as price.
Frequently asked questions
How are hidden leaks found?
Depending on the situation, plumbers may use pressure testing, acoustic equipment, thermal imaging, moisture meters or targeted camera inspection.
Does leak detection include the repair?
Not necessarily. Confirm whether detection, access, repair and restoration are separate parts of the quote.
Can I check for a leak myself?
A meter test may reveal ongoing water use, but professional diagnosis is often needed to identify the source and repair it safely.
