Professional Leak Detection Services in Clapham

Hidden leaks are one of the most common causes of water damage in properties across Clapham and South London. A concealed leak behind a wall, beneath flooring, or within a ceiling cavity can cause extensive structural damage and dangerous mould growth long before any visible signs appear. Our non-invasive leak detection service uses advanced thermal imaging and acoustic technology to pinpoint hidden leaks with precision — without destructive investigation.

Our IICRC-certified leak detection technicians locate the exact source of water ingress quickly and accurately, saving you the time, cost, and disruption of exploratory demolition. Whether you suspect a slow leak or need to find the source of unexplained water damage, our advanced detection equipment identifies the problem so repairs can be targeted precisely.

Our Leak Detection Methods

  • Thermal imaging — Infrared cameras detect temperature variations caused by moisture behind walls, beneath floors, and within ceilings. This non-invasive technique reveals hidden moisture patterns invisible to the naked eye.
  • Acoustic detection — Highly sensitive microphones and ground sensors detect the sound of water escaping from pressurised pipes, even through concrete, brick, and tile.
  • Tracer gas testing — A safe, inert gas is introduced into the pipe system and specialist detectors locate the exact escape point, even in complex or inaccessible pipework.
  • Moisture mapping — Calibrated moisture meters and hygrometers create detailed moisture maps showing the extent and distribution of water penetration throughout the affected area.
  • Endoscopic inspection — Miniature cameras inspect inside cavities, pipe runs, and concealed spaces without the need for large access openings.

Common Signs of a Hidden Leak

Contact us for professional leak detection if you notice any of the following in your Clapham property:

  • Unexplained damp patches on walls, ceilings, or floors
  • Musty or damp smell that persists despite ventilation
  • Unusually high water bills without increased usage
  • Sounds of running water when all taps are turned off
  • Mould growth in unexpected locations
  • Bubbling or peeling paint and wallpaper
  • Warm patches on floors (indicating a hot water leak)
  • Reduced water pressure throughout the property

Why Non-Invasive Leak Detection Saves You Money

Traditional leak finding methods often involve removing tiles, cutting into walls, and lifting flooring to locate the source — creating additional damage and repair costs. Our non-invasive technology pinpoints leaks from the surface, so repairs can be made through a single, precise access point. This typically saves property owners thousands of pounds in unnecessary demolition and reinstatement costs.

Frequently Asked Questions

Our thermal imaging cameras detect temperature variations as small as 0.05°C, making them extremely accurate at identifying hidden moisture and leaks behind walls, beneath floors, and within ceilings. Combined with acoustic detection, we achieve a pinpoint accuracy rate exceeding 95%.
Yes, our acoustic detection equipment and tracer gas testing can locate leaks beneath concrete slabs, screeds, and tiled floors without any need to break through the surface. Once the leak is pinpointed, only a small, targeted access point is needed for repair.
A standard residential leak detection survey in Clapham typically takes 1 to 3 hours, depending on the size of the property and complexity of the pipework. We provide a detailed report with findings and recommended repair actions on the same day.
