Our Leak Detection Process

Here’s how we ensure your plumbing system stays efficient and leak-free:

01

Leak Inspection & Diagnosis

Our experts conduct a full inspection using thermal imaging, pressure testing, and acoustic sensors to identify leaks, no matter how hidden they are.

02

Leak Location & Assessment

Once we locate the source, we assess the severity and provide a detailed action plan, ensuring minimal disruption and the most effective repair solution.

03

Professional Repairs

Our licensed plumbers use high-quality materials and proven repair methods to fix leaks properly, preventing future issues and maintaining your plumbing’s integrity.

How Hidden Leaks Can Damage Your Property

A small, unnoticed leak might not seem urgent, but over time, it can cause serious structural damage. From rotting timber to weakened foundations, hidden leaks can lead to expensive repairs if left unchecked. Here’s what they can do:

Mould & Mildew Growth – Damp conditions encourage mould, which can cause respiratory issues and damage walls.
Foundation Cracks & Soil Erosion – Leaking pipes underground wash away soil, leading to shifting foundations and structural instability.
Peeling Paint & Water Stains – Leaks inside walls cause bubbling paint, discoloured ceilings, and visible water damage.
Increased Water Bills – Even a slow, steady leak wastes thousands of litres of water, driving up costs.
Electrical Hazards – Water near electrical wiring creates a serious fire and safety risk.

Advanced Leak Detection Technology

Finding leaks used to mean guesswork and property damage, but modern technology allows us to detect leaks with pinpoint accuracy—without tearing up walls or digging unnecessary holes. Here’s how we do it:

Thermal Imaging Cameras – Identify moisture patterns inside walls, under floors, and in ceilings.
Acoustic Leak Detection – Uses sensitive microphones to detect leaks through sound variations in pipes.
Pressure Testing – Confirms hidden leaks by measuring pressure fluctuations in your plumbing system.
Moisture Meters – Detects excessive dampness before visible signs appear.
Gas Tracer Leak Detection – Ideal for pinpointing underground leaks without digging up your yard.

Hi there. Work required to be was to install tapware and a laundry tub as well replace a burst inlet pipe in the bathroom. This was done well. However one of the new taps was not installed straight and it as an angle to the wall. Also the board under the waste-paper below the tub was cut roughly. Photos attached.
We have dealt with Steve Bennett Plumbing several times over the years and have been happy with their service.

My partner found this highly rated business online and we believed it was a great as we relied on Google reviews. We were thoroughly disappointed with the communication and the service provided in two occasions.

1. Day 1: Our apartment (where we have tenants now) drain was clogged and contacted Steve Bennett plumbing to access and fix on 7/3/24. They had managed use a drain solvent to unclog. We were charged $236 for call out fee and product used. At this point we were pleased that it was just clear and were happy to pay for their service.

2. Less than a week later 13/3/24 the drain was clogged again so we wanted to check in with the plumbing service and asked for their recommendation on what to do. They offered a pressure wash and to lodge a camera to see what they could do to help fix. They also offered no call out fee and mentioned they'd have a member check it out on the Friday 15/3/24 on the same week. We agreed to the service and wanted to go ahead with their recommendation.

3. The service was completed and we received a quote of the same exact service - liquid drain solvent poured down and call out fee. We were confused and frustrated that what was promised was not delivered but in fact the same solvent was poured down the drain with $236 invoice sent to us to be paid again. Frustratingly we called the team and asked why they offered to service of pressure wash and camera to access issue and why it was not actioned. We were fine to pay but would have appreciated some communication to what we agreed on.

4. We called today and they apologised and mentioned it could be a bigger issue. (This was why we agreed to the camera assessment). We are not happy customers and will no longer be using their services again.
