A plumber can fix most visible plumbing leaks without delay. However, if the source of a water leak is hidden, a leak detection specialist is a better option. They can accurately locate leaks without exposing pipes.

Unlike some leak detection companies, we offer a complete end-to-end service. Our water leak detection services in London include:

Trace and access investigation
Support for home insurance claims
Water leak repairs
Full reinstatement of water damaged areas

An Aspect leak detection expert will help prevent further damage to your property. They’ll locate the source of a water leak or ingress. A detailed report is provided as part of every investigation. Finally, they’ll provide a fixed price quote for repairing the problem, including full refurbishment of any water damaged areas.

Recent customer reviews

Excellent service from Michael and team of Aspect. An underground leak was quickly identified, and its precise location pin-pointed swiftly with up-to-date equipment. It required digging which was kept to a minimum. Michael liaised with Thames Water and repaired the leak in record time. Overall very professional work.

Adam, Marlow, SL7
We had a hidden leak on our central heating system. Nabeel from Aspect was booked to carry out a detailed check of the entire system. He attended and did a gas trace test. An in-depth investigation was carried out and located an area of concern from the findings. Quick turn around, problem solved and highly recommend!

Ben, Kentish Town, NW5
Leak detection engineer explained how my house's plumbing works and some issues that I may want to fix in the future. He showed me how he searched for the leak and I got a better understanding of how the whole process works as he explained each step. In the end, he found and fixed the leak. Very happy with the service.

Claudimila, Southall, UB2
I was really impressed with the work done by Aspect and more specifically Dean who helped fix a leak for me. He did a thorough check and made sure there were no other issues and left me feeling confident our problems have been resolved.

Damian, South Ockendon, RM16
A leak detection specialist arrived on time and using various testing methods managed to identify the source of my leak. He was friendly and helpful and did just what I needed him to do.

Garth, Sudbury, CO10
Dean was fantastic. He quickly established the cause of the leak, dealt with the issue and explained it very well. He was courteous and pleasant to deal with. The speed of service, given the urgency, was brilliant too.

Harry, Dorking, RH5
The engineer who came to source the leak was highly experienced and in no time he found the leak which was beneath the shower tray in the bathroom. We'd had several plumbers who couldn't find the leak before. Therefore I can only highly recommended him for the leak detection work.

Javed, Basingstoke, RG23
The experience was made great because of the people you sent, especially Ali. He was thoughtful e.g. asking us if it was OK to turn off the water and treating us and our house with respect. He liaised with Thames Water and took that pressure from us and most of all he knows his trade so the technical aspects of the leak detection were not traumatic because we had confidence in him.

Leonie, Windsor, SL4
I've had a ceiling leak issue for several years, and have had many people round to advise and try and fix, but nothing had worked. Adam had worked out the issue within an hour, and already provided directions on a plan to fix it permanently. Nothing more needs to be said - if you've got a leak he's going to detect it.

Matt, Haverhill, CB9
Marcin arrived on time for leak detection work in our basement. The leak was detected and I feel he made a thorough investigation. He has to come back again to check if this was the only avenue for water to get in and check if it’s has all dried up after his remedial works, but we are very happy with what he has done so far and feel he was extremely kind and understanding throughout this job. Thank you so much!!

WATCH: How we detect leaks

Most specialist leak detection companies use similar methods. There isn’t one method that’s used to locate any type of leak. Normally, several techniques are used on how to find a water leak. Results from each technique allows attention to be focused in a specific area.

We’ve produced a series of videos to show examples of how the water leak detection techniques are used in different situations.

This video shows some of the techniques used when the source of damp could be either plumbing pipes or the roof.

Non invasive detection methods

The equipment used by our leak detection services for locating leaks are mainly non destructive. Leaks can be traced without having to expose pipes. The approach is cost effective compared to exposing parts of a property in the vain hope of finding a leak.

This approach is required by most insurance companies when an “escape of water” claim is being made.

Detection methods include:

Thermal imaging
Tracer gas
Acoustic surveys
Moisture meters
Borescope cameras
Salts analysis

Qualified tradespeople

Each of our leak detection tradespeople has a background in a specialist trade. This means we can schedule someone with the most relevant knowledge for every investigation. We can predict the type of leak based on information we ask at the point of booking. For example, if a boiler is losing pressure, and a central heating leak is suspected, we’ll send a leak detection expert who’s Gas Safe registered.

As well as finding leaks in plumbing and heating systems, we can find any other type of leak in a property. We have expert roofers to investigate leaking roofs and gutter problems. We have drainage engineers to investigate waste and soil water leaks. We even have builders to detect water ingress through brickwork and masonry.

All of our leak detection experts are fully equipped and can find a leak anywhere in a property. Their relevant trade knowledge means they can usually fix the problem quickly. It also means they can usually provide a fixed price quote for subsequent refurbishment work quickly.
