The single most typical cause of a swimming pool leak is damaged pipes on the filtration system caused by ground movement, other causes include defective filtration system fittings or damage to the pool structure. Our PADI Trained divers offer a SPATA certified swimming pool leak detection service to find the source of swimming pool leaks

Water Mains Leaks

Water supply leaks can show as an internal or external water leak. A high water bill is a sign of a leaking water supply line. The single most common location of a water main leak is outside where the water supply line is affected by ground movement which causes pipes to rupture or fittings to become defective. Our technicians carry out a water meter leak test to determine if the leak is internal or external, then undertake a leak detection investigation to locate the leak.

Underground Water Leaks

Underground water leaks come from water supply lines, irrigation systems or drainage pipes. Causes of underground water leaks include ground movement, deteriorated pipes, tree root damage or faulty installations. We identify underground water leaks by firstly evaluating which pipes are below the ground. Our non-invasive leak detection process is used to locate the location of the leak without causing damage to the ground surface.

Underfloor Pipe Heating Leaks

Under floor heating leaks typically arise on the manifold valves, circuit pipes and from loose fittings. Causes of leaks on under floor heating circuits include damaged pipework, faulty installation, damage to the pipes, age or a inadequate maintenance routine. Our specialists identify leaks on under floor heating circuits using thermal imaging, tracer gas and acoustic listening devices.

Building Leaks

Building leaks occur in the roof, walls or foundations of a building due to settling of building materials, subsidence, inadequate construction or neglected maintenance. Our structural leak investigation team detect leaks in building materials including concrete, brick and wood using a selection of leak detection techniques including Tracer gas leak testing, thermal imaging and acoustic listening devices.

Flat Roof Leaks

Roof leaks range from slow water intrusion causing damp to a severe flow of water in heavy rainfall. Roof water penetration develops where there are missing tiles, damaged flashing, crumbling mortar or damage around a chimney. Causes of leaks on roofs include storm damage, substandard construction, neglected maintenance and wear and tear as the roof gets older. Pinpoint the source of your roof leak by choosing our highly professional roof leak investigation professionals.

Shower and Bathroom Leaks

Shower and bathroom leaks originate from hidden pipework behind walls, beneath the bathtub, shower tray or sink. Causes of shower and bathroom leaks include deteriorated fixtures, fittings, washers and seals along with corrosion of pipes and loose plumbing fixtures. Our plumbing leak detection engineers locate leaks on bathroom pipework including hot and cold feeds to showers, baths, sinks and toilets using non destructive leak detection equipment. Eliminate further water damage to your property!

Drainage Leaks

Drainage leaks occur on internal and external drain pipework. Causes of leaks on drain pipes include split pipes, broken seals, blockages, loose connections along with tree roots and ground movement. A drainage system is not pressurised so leak detection methods are limited to CCTV surveys inside the drainage pipe. Our drainage engineer delivers a thorough inspection to pinpoint the cause of the leak and are usually able to complete a repair on the same day.

FAQs - Leak Detection in London

Do you guarantee to find my leak?

Not a single leak detection company can guarantee locating any leaks. However, we deliver a No leak-No charge service for water mains leaks on individual properties where the mains are less than 30 m long and losing in excess of 30 litres per hour.

Will leak detection damage my property?

No. Our non invasive leak detection methods do not damage your property. Occasionally, we may need to drill a small 5mm hole into a cavity for camera access. No matter where the leak's location, minor damage could be necessary to access and repair it.

Will you disconnect the water while leak detection?

We usually won't need to switch off your water supply during leak investigations. However, we may need to close the stopcock briefly when performing repairs.

How long does it take ?

Leak detection usually takes from a couple of hours to a full day or beyond. The time needed to discover the leak source depends on the nature of the leak, its location, and the complexity of the investigation.

Will you mend my leak?

Yes. We will repair plumbing system leaks on the same day as detection, provided our engineer has adequate time after locating the leak. Repair charges apply separately.

Can you aid me with my insurance claim?

Yes. We offer insurance-approved reports for claim purposes. If your home insurance contains "Trace and Access" protection, you can recoup the leak detection costs.
