Seven days a week, 7am to 9pm
If none of these matches, describe the problem on the phone and we will tell you which applies.
Damp on a corridor floor with nothing visible above it. Pressure testing each circuit separately put the fault on the cold feed, and acoustic listening put it under the bathroom tiles.
Cold feed pipe leak found and repaired beneath bathroom floor.
A leak notice from the supplier, wet walls in the garage, and an internal stopcock that would not shut the water off. Tracer gas and acoustic listening agreed on the same corner.
Underground mains leak found in garage, pipe repaired.
Heating pressure falling by about a bar every twelve hours, and damp in the bathroom where somebody had already had the floor up once.
Failed copper fitting found and replaced beneath the bathroom floor.
There is no second appointment to move on to, so an investigation that needs six hours is given six hours.
It is not an offer to attend on the day you call. Engineer days are booked in advance. Where one is unbooked, or an earlier job finishes early, same-day attendance is possible.
Thermal imaging, acoustic microphones and tracer gas read through tile, screed and concrete. Any opening is small and in a single location.
Our engineers are plumbing and heating engineers as well as leak specialists. Supply and heating repairs are normally completed and pressure tested during the visit.
Describe what you have seen: a damp patch, a pressure drop, a higher bill. We establish which equipment the job needs, find the nearest available engineer, and confirm a date and a price.
Each engineer is assigned one property per day. There is no second appointment to move on to, so the investigation runs for as long as the job requires.
Thermal imaging, acoustic microphones, tracer gas, correlation and moisture mapping. No single method is relied on alone. The search continues until two or three agree on the same point.
You receive the exact location, photographs and a report written for an insurer. Where the repair is straightforward, our plumbing and heating engineers complete it on the visit and pressure test it.
Figures published by ADI Leak Detection. Trustpilot score read on 22 September 2026.
We had a major water leak of approximately 220 litres per hour and, with a holiday booked only a few days later, we urgently needed someone to find and repair it. […] Frank arrived at our house. He was extremely polite, professional and clearly very experienced. He quickly set up the equipment, carried out a tracer gas test and pinpointed the leak to an area just outside our garage underneath the driveway. […] The whole job, from arriving at our house to finding and repairing a 220 litre-per-hour leak, was completed in around three hours.
Shortened. The marks show where text was left out.
Fundamentally, the engineer (Mark Pavitt) identified the source of the leak, repaired it and had our house back up and running within the same day. As part of achieving this, he kept the damage to a minimum (only having to cut out sections of the kitchen plasterboard ceiling). He cleaned up the debris, was polite, cheerful and informative of root cause and actions throughout the day. I think the key to success is having an engineer that has expertise in both leak detection and plumbing.
Very professional and swift service. Frank arrived and had detected and repaired the leak within 3 hours. Would highly recommend
Occasionally. Engineers are assigned one property per day and those days are booked in advance. Where one is unbooked, or an earlier job finishes early, same-day attendance is possible. You will be given the earliest date genuinely available.
It refers to the visit. One engineer spends the full day on your property, and across every job ADI has attended the leak is located on that day in about ninety-nine of a hundred. Where the repair is straightforward it is completed before the engineer leaves.
Say so at the start of the call. Water that cannot be isolated is prioritised as far as availability allows, and you will be told what can be arranged and when.
A full day is allowed for every pipework investigation. Some leaks are located within the hour. The remainder are the ones that need the time, and that time is already reserved.
In most cases, no. Thermal imaging, acoustic listening and tracer gas locate the leak through tile, screed and concrete. Where the pipe has to be reached, the opening is small and in a single location.
One call confirms the earliest available date and the price, before you commit to anything.
Seven days a week, 7am to 9pm. Most home insurance covers the cost of finding a hidden leak.
