Before you book
What you need to know.
- Dampness shows where water reached, which can be some distance from its source.
- Compare water use, fixture behaviour and rainfall before assuming there's a buried supply leak.
- An investigation should narrow the fault before a repair opening or replacement route is agreed.
- The repair, access work and reinstatement need clear descriptions.

Water use and visible dampness tell different stories.
A high bill, damp skirting or a wet patch in the garden can all prompt a leak enquiry. They don't necessarily point to the same job. A running toilet uses metered water but may leave no wet floor. Rain entering around a roof junction can leave a ceiling stain without changing the meter. A shower waste fault may appear only when that shower is used.
Describe the timing before trying to identify the pipe. Note whether the area stays wet through dry weather, whether a particular fixture triggers it and whether the water has an odour. Scott & Sons can use that information to investigate the relevant plumbing rather than treating every damp patch as a failed supply line.

| What you notice | What needs separating |
|---|---|
| Higher water use without visible water | Fixture losses, changed usage and concealed supply leaks |
| Dampness after a shower | Supply, waste connection and waterproofing issues |
| A mark appears after rain | Roof drainage, stormwater and other building entry points |
| Water beside a toilet or vanity | The fixture, its connections and water travelling from elsewhere |
A meter check can add useful information.
If you have your own accessible meter, Sydney Water explains how to compare readings while no taps or water-using appliances operate for at least 1 hour. A change shows water passed through the meter during that period. Irrigation, appliances and a toilet refilling unnoticed can affect the result, so account for these before interpreting it.
A still meter doesn't rule out every intermittent leak, drainage fault or rainwater entry. In a shared building, other occupants may use the same supply. Give the plumber your readings and test conditions rather than treating a brief check as a diagnosis. Don't delay an urgent call to complete a test when water is already causing damage.
What the investigation needs to establish.
The useful outcome is an explanation of the source, the affected system and the evidence for the proposed repair. An investigation may start with accessible fixtures and connections, then progress to checks of the relevant water circuit or drainage. The sequence depends on what the observations reveal and which areas can be reached.
Ask what the first attendance covers and how additional investigation is approved. Specialist location equipment may suit concealed faults, but identifying the right system comes first. Scott & Sons' published services include leak detection and CCTV drainage investigation; the method and equipment for your property should be confirmed when the job is discussed.
Repair a section or change the route?
An accessible connection is a different decision from damaged pipework under a finished floor. Once the fault is located, compare the affected section's condition with the disruption needed to reach it. A targeted repair can suit serviceable surrounding pipework. A replacement run deserves consideration where deterioration extends beyond the visible break.
Ask how the options affect floors, cupboards, external surfaces and future access. Reinstating a tiled floor can be a substantial part of the project even when the pipe repair is limited. Rerouting isn't suitable everywhere, and a leak doesn't automatically justify replacing all the property's plumbing. The recommended extent should relate to what was found.
What affects the investigation and repair cost.
Access, the number of possible sources and earlier records influence investigation time. A visible fixture leak can be assessed differently from a fault spanning units, a concrete slab or several concealed routes. Previous repairs and a symptom history help prevent the investigation starting without context.
Have the quote identify investigation, plumbing repair, any opening of surfaces and the party responsible for reinstatement. Ask how unresolved findings or further access will be handled. A price for an unspecified hidden repair isn't directly comparable with a quote that defines what can currently be known. Keep these distinctions visible when deciding whether further investigation is worthwhile.
Prepare a record without disturbing the area.
Take photographs from a safe position and record when the problem appears. Keep water bills, repair invoices and building reports handy. For an apartment, provide the unit number, affected neighbouring areas and the building manager's contact so access can be coordinated.
Keep clear of wet electrical equipment, damaged ceilings and unstable ground. Don't open walls or dig to find a pipe before the assessment. If water is actively escaping, phone 02 9482 9199 and describe the immediate conditions; a form is better suited to a planned investigation.
Describe the pattern
Say where water appears, when it started and which use or weather seems connected.
Agree the investigation
Confirm access, initial checks and who can approve further work.
Choose the repair
Review the source, repair alternatives and any surface work before approving the scope.
Keep the findings
Retain the repair details and observe whether the original symptom returns.
