Six diagnostic tools. One definitive answer.
We bring everything on every job — so the leak is found the first time, whatever its hiding place.
Thermal Imaging
ITC-certified infrared cameras reveal temperature differences caused by escaping water, even through tile, screed and plasterboard.
Tracer Gas
A safe hydrogen/nitrogen mix is introduced at low pressure; sensors detect it escaping at the exact point of leak.
Acoustic
High-sensitivity ground microphones and pipe-mounted sensors hear leaks under concrete, tarmac and timber floors.
Moisture Mapping
Protimeter moisture meters and pinless scanners chart the spread of damp across walls, ceilings and floors.
CCTV Drain Survey
HD drain cameras inspect soil, waste and surface-water drains with on-screen distance and defect logging.
Pressure Testing
Full system pressure tests confirm whether supply, heating or drainage pipework is losing water and how quickly.
The specialist choice when a plumber isn't enough.
Fixed pricing, confirmed in writing
No hourly creep. You know the price before anyone arrives.
Insurance-approved reports
Every survey ships with a Trace & Access report your insurer will accept.
Same-day London availability

Non-invasive first
We find the leak before a single tile is lifted — saving you thousands in reinstatement.

“Boiler kept losing pressure for months. The engineer found a pinhole leak under the kitchen floor in under two hours — no mess, no demolition. Report was with Aviva the same afternoon and the claim was approved.”

“Leak was showing on the ceiling in our downstairs bathroom. Thermal imaging picked it up straight away — turned out to be the shower waste two metres away, not where I expected. Honest, tidy, and well-priced.”
Trustpilot · February 2026
“Managing agent had tried three plumbers before us. Their tracer gas kit found the leak in the riser within 40 minutes. Report went to the freeholder's insurer and sorted everything.”
