Leak Detection Specialist Services For All Hidden Leaks

A plumber can fix most visible water leaks without delay. However, if the source of a leak is unknown, a leak detection specialist is a better option. They can accurately locate leaks without causing damage.

We offer an end-to-end service. Our leak detection specialist services include:

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

An Aspect leak detection specialist will help prevent further damage to your property. They’ll locate the source of a leak before accessing it for visual confirmation. A detailed report is provided along with a fixed estimate for repairs and reinstatement.

WATCH: How we detect leaks

Most leak detection companies use similar methods. There isn’t a single method used to locate a specific type of leak. Typically, several trace and access techniques are used. Results from each method allow attention to be focused on a particular area.

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

Leak detection customer reviews

From the moment he arrived, it was evident that the tradesman possessed extensive knowledge and experience in their field. He meticulously examined every possible area of concern, leaving no stone unturned. His determination and hard work in identifying the source of the leak were truly impressive. He also demonstrated exceptional skill in resolving it to the highest standard.

Adham, Kensington, W8
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 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
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!!

Nadia, Watlington, OX49
Prompt service, arrived when they said they would, kept us updated with progress detecting the leak and were incredibly clean and thorough. Lee and Darren were 100% on the job and were fantastic. Professional, helpful, and super clean tidying up after the work was done too. Also great at dealing with a difficult neighbour.

Frequently asked questions

How much does leak detection cost?

Our leak detection investigations are charged in half-hour increments, so the cost depends on the time it takes to trace the leak and identify the cause.

Specialist tracer gas is sometimes used to pinpoint leaks, which is charged for, along with any materials used in any repairs undertaken. Surveys are generated while at the site, so there is no additional charge for the report.

The only type of leak we can’t investigate at night is roofing leaks. This is due to health and safety regulations.

Check our half-hourly rates for your area.

How long does a leak detection investigation take?

The time required for an investigation depends on factors such as the type of leak, the size of the property, and the complexity of the building’s structure.

As a guide, a bathroom leak in a typical semi-detached house might take up to 4 hours to locate, whereas a leak in a commercial mains water supply pipe can take more than a day.

An estimated total investigation time can usually be provided after the first 2 hours.

Is leak detection covered by insurance?

Most property insurance policies contain a clause for “trace and access” or “escape of water”. Water damage caused by plumbing, drainage, and heating system leaks is usually covered. Roofing leaks caused by general age, weathering, or poor installation are not usually covered.

Insurance policies cover different parts of a leak’s investigation, access, repair, and reinstatement phases, so you should read your policy or contact your insurer.

Our comprehensive guide lets you learn more about making a successful “escape of water” claim.
