By London’s Leading Leak Detection Specialists
Hidden leaks are one of the most damaging and expensive problems property owners face. A small, unseen leak behind a wall, under the floor, or inside a heating system can cause damp, mould, structural damage, and soaring water bills long before you notice anything is wrong.
At our company, we specialise in non-invasive leak detection London, using advanced technology to locate leaks accurately without drilling holes, ripping up floors, or damaging your property unnecessarily. Once the leak is found, our engineers also carry out the repair, providing complete trace and access specialists service from start to finish.
Here’s everything you need to know about how non-destructive leak detection works and why it’s the safest, fastest, and most cost-effective solution for hidden leaks.
⭐ What Is Non-Invasive Leak Detection?
Non-invasive leak detection London means finding hidden water leaks without damaging your property.
Instead of smashing tiles or guessing, we use technology that allows us to detect leaks through floors, walls, ceilings, concrete, underground pipework, central heating systems, and underfloor heating.
This method saves time, money, and prevents unnecessary destruction.
⭐ Signs You May Have a Hidden Leak
If you notice any of the following, you likely have a concealed leak:
- Boiler losing pressure
- Damp patches or mould
- Hot or cold spots on the floor
- Musty smells
- High water bills
- Stains on ceilings or walls
- Sound of running water
- Underfloor heating not working properly
Early detection is essential to avoid long-term damage.
⭐ How We Locate Leaks Without Damaging Your Property
Our specialist engineers use a combination of advanced equipment to pinpoint the exact leak location.
1. Tracer Gas Leak Detection
Tracer gas leak detection London is inserted into the pipework to find even the tiniest leaks. It rises through floors and walls, and sensitive detectors identify the exact escape point.
Ideal for central heating leak detection, underfloor heating leaks, and buried pipes.
2. Thermal Imaging Cameras
These detect temperature changes caused by escaping water. Perfect for locating leaks behind walls, under floors, in heating systems, or bathrooms.
3. Acoustic Leak Detection (Listening Equipment)
Leaks create unique sound frequencies. We use specialised microphones to pinpoint the exact area of the leak.
4. Moisture Mapping
Moisture meters track moisture patterns in floors, walls, and ceilings, revealing the path of escaping water and helping confirm the leak area.
5. Borescope Camera Inspection
A tiny camera is inserted through a small pinhole, allowing us to see inside cavities without damage. Ideal for behind tiles, inside walls, or ceiling voids.
⭐ Once We Find the Leak — We Repair It Too
Many leak detection companies only locate the leak and leave you to hire a plumber. We provide complete trace and access leak repair service.
After locating the leak, we:
✔ Make minimal access (only where needed)
✔ Repair the leak professionally (pipework, fittings, etc.)
✔ Test the system again to ensure the leak is fixed
✔ Provide a full report with photos/videos for insurance
✔ Recommend preventative measures
This saves you the stress of hiring multiple companies and speeds up insurance claims.
