London 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
Certainly a fast response, even though this wasn't an emergency. The engineer (Kenneth Croxon) traced the source of an intermittent leak, which previously had been hard to track down, and fixed it. So, good result.

Anthony, Belsize Park, NW3
As always excellent service from Aspect! Darren was incredibly patient, efficient and did an excellent job! I can highly recommend both him and Aspect!

Dionne, Battersea, SW11
After consulting surveyors who diagnosed rising damp and then shelling out for an expensive damp course, problems with a damp floor in my kitchen persisted. I called in Aspect and their operative quickly showed the water was pipe water not ground water and therefore the problem was not and had never been rising damp. He performed several other thorough tests, found the exact point of the leak before fixing it and reinstating the floor.

Helen, Chigwell, IG7
Luke couldn’t have been any better. He was very friendly and clearly knowledgable. He arrived on time, diagnosed the problem and the cause. I’d been particularly concerned about this so it was reassuring to have him carry out the leak investigation. I’ll definitely be using you again for anything like this in the future.

Levi, Wapping, E1
The leak detection engineer Csaba that visited my property was fabulous. He was so warm and professional. He knew exactly what he was doing. Overall, from start of booking the appointment to finish, am very impressed with the service. Highly recommend Aspect. Thank you.

William, Clerkenwell, EC1

Leak Detection experts

Trace and Access Leak detection techniques

The equipment used by our leak detection experts is mainly non-destructive. This approach is required by most insurance companies when processing an “escape of water” claim. Detection methods include:

Thermal imaging
Tracer gas
Acoustic surveys
Moisture meters
Borescope cameras
Salts analysis
Pressure tests
Tracer dyes
Electric voltage tests

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.

Can leaks be detected out of hours?

Aspect is one of the largest leak detection companies in the UK. We provide emergency leak detection services 24 hours a day, 365 days a year.

In an emergency, we aim to have a leak detection specialist at your property within 1 hour of receiving a booking. There is no extra charge for emergency attendance. Our half-hourly attendance rates start from £49.50 + VAT.

Trade accredited experts

With years of experience in their respective trade, our trace and access leak detection experts can carry out the necessary leak repairs and accurately estimate the cost of reinstatement work.

Our team includes Gas Safe registered heating engineers, plumbers and experts in flat and pitched roof coverings.

Experience shows this approach is more efficient and less problematic than passing responsibility from one person to another to resolve a water leak fully.

Leak detection investigation costs

Our competitive prices are charged in half-hour increments (1-hour min.). If tracer gas is needed as part of an investigation, it will be charged in addition to the half-hourly rate.

From £49.50 + VAT on weekdays
From £65.25 + VAT on evenings and weekends
From £85.50 + VAT for late nights (9pm to 7am)

Duration Discounts

A discount to the half-hourly rate will be applied to your invoice if our tradesperson is on-site for extended hours:

Half day (4 hours & more) = 5% off
Full day (8 hours & more) = 10% off

Emergency Attendance

Making an insurance claim

An insurance company processing an “escape of water” claim usually stipulates that a leak detection company, like Aspect, is engaged and can find leaks using trace and access methods.

This non-invasive approach requires a range of tests to be carried out methodically. Our leak detection engineers frequently find leaks away from visible water damage. Invasive investigations based purely on assumptions often mean damage to a property without finding a leak.

A report detailing the methods, findings, photos, and recommendations supports our investigations.

For information about how leak detection works, we’ve answered the most common customer questions on our FAQs page.

Full-service detection & repairs

There are usually three stages insurers will consider. Yours will be clear on which of these they cover.

Trace and access detection of the leak and visual confirmation
Repairs to stop the leak and prevent further water damage
Reinstatement of the water-damaged parts of the property and damage from exposing and repairing the leak

We provide a complete and comprehensive leak detection service, including accessing and repairing leaks and reinstating the affected areas to their former condition.
