Expert Gas Leak Detection Services Across Perth's Southern Suburbs

Suspect a gas leak at your home? Never treat a gas leak as a wait-and-see problem. An unusual gas odour or unexplained change in gas use can indicate a problem with your gas supply, appliances or pipework.


Tactical Detection provides professional gas leak detection services in Perth's southern suburbs, with a local base in Baldivis and coverage extending through the Rockingham, Mandurah and Peel Region corridor.


Our focus is simple: accurately identify the source of the suspected leak, determine what needs attention, and, where the scope allows, complete targeted repairs without unnecessary disruption to your property.

Leak Detection

Suspect a Gas Leak? Act Safely First

If you can smell gas, hear a suspected gas leak or believe gas may be escaping, prioritise safety before arranging a standard service visit.


Do not use flames, matches, lighters or anything that could create a spark. Avoid operating electrical switches or appliances in the affected area. Move away from the source and evacuate the property if necessary.


If you know where the gas isolation valve is and can safely access it without entering an unsafe area, you may turn off the gas supply. Do not put yourself at risk to reach the meter, valve or suspected leak.


For a suspected natural gas leak in WA, current government guidance recommends reporting the incident to the relevant gas supplier. You can contact ATCO Gas Faults and Emergencies on 13 13 52. If there is a fire, immediate danger or a life-threatening emergency, leave the area and call 000.



Once the immediate risk has been addressed, a licensed gasfitter can investigate the installation and determine whether repair work is required.

Professional Gas Leak Detection Service in Southern Perth

A suspected gas leak needs more than a quick visual check. The source may be associated with gas appliances, connections, valves, or concealed pipework, so accurate diagnosis is important before repair work begins.


At Tactical Detection, we investigate suspected gas leakage systematically to help establish where the pressure loss or escape is occurring. The aim is to identify the affected section so that any required repair can be targeted rather than relying on guesswork.



Gas leak detection is also different from water-leak diagnostics. Techniques and safety requirements depend on the system being investigated, which is why suspected gas issues should be assessed by an appropriately licensed gasfitter rather than tested with DIY methods.

Signs That May Indicate a Gas Leak

Gas leaks do not always present in exactly the same way. Depending on the source and circumstances, you may notice:


  • An unusual or rotten-egg-like gas odour
  • Gas appliances behaving differently from normal
  • An unexplained increase in gas usage
  • A suspected issue around a gas appliance, connection or pipe
  • Physical symptoms such as dizziness, nausea or headaches when around a suspected gas source


An odour is particularly important because fuel gases are given an added smell to help make leaks detectable.



Do not attempt to locate a suspected gas leak yourself using flames, electrical equipment or improvised testing methods. If you suspect a leak, follow the appropriate safety response first and have the installation assessed professionally.

Is There Water in Your Gas Lines?

Water entering a gas line is rare but can cause serious problems. It can occur when a failed water line forces water into the gas main, potentially pushing water back through the gas meter and into connected appliances.



If you suspect water has entered your gas lines, do not attempt to fix it yourself. Contact a licensed gasfitter to safely assess the system and determine the required repairs.

What Happens During a Gas Leak Detection Visit?

When you contact Tactical Detection, we will first ask about what you have noticed and whether there are any immediate safety concerns.


A gas leak assessment may involve:


  1. Understanding the symptoms – We discuss where the odour, sound or appliance issue has been noticed and when it began.
  2. Assessing the gas system – The relevant gas supply, appliances, connections and accessible pipework are considered as part of the investigation.
  3. Carrying out professional detection – Appropriate diagnostic methods are used to investigate the suspected source and identify pressure loss or leakage.
  4. Locating the affected area – The objective is to establish where the issue is occurring so unnecessary disturbance can be avoided.
  5. Explaining the findings – We outline what has been identified and what action may be required.
  6. Discussing repairs – Where the work is within scope, we can discuss targeted repair options and the next steps.


The exact detection procedure and equipment used will depend on the installation, access and nature of the suspected leak.


Tracer Gas


Where appropriate, tracer gas can be used as part of professional leak detection. It is a safe, calibrated gas used to help confirm pressure loss associated with very small pinhole leaks and difficult-to-locate failures.


The appropriate detection method will depend on the gas system and the circumstances of the suspected leak.

Why Use a Licensed Gasfitter?

Gas installations require specialist knowledge and must be worked on by appropriately licensed professionals. Choosing a licensed gasfitter helps ensure the issue is assessed and repaired with the necessary safety and compliance considerations in mind.


Tactical Detection brings 22+ years of experience as qualified contractor plumbers and gasfitters, combining plumbing and gas expertise with specialist diagnostic equipment.


Gas Licence: GF23632


Our approach is focused on accurate diagnosis, safe work practices and targeted repairs. Where documentation or further work is required, we can explain the findings and the recommended next steps.

Detection and Repair in One Service

Finding the leak is only part of the solution. Where the source is accessible and the required work falls within the scope of the service, Tactical Detection can provide a mobile repair-on-site solution.


This can help avoid the need to coordinate multiple trades and allows the issue to move from detection towards resolution more efficiently.


However, not every repair can be completed during the initial visit. Access, the location of the pipework, the complexity of the fault and the nature of the required works will determine what can safely be completed on-site.



Our priority is to identify the problem accurately first, then recommend the appropriate repair.
