Boiler Leaks

Central heating heating leaks are usually buried beneath floors, behind walls or cavities. A boiler dropping water pressure is the most likely sign of a leaking central heating system, further symptoms include water damage or having to frequently bleed radiators. Our experts pinpoint the source of heating leaks, whatever the cause or location of the leak using non invasive leak detection equipment. Our plumbing engineers provide a same day central heating leak repair service.

Pool Leaks

Swimming pool leaks originate from the pool structure, liner or be anywhere on the filtration system. The single most likely cause of a swimming pool leak is damaged pipes on the filtration system caused by ground movement, more causes include loose filtration system fittings or damage to the pool structure. Our PADI Trained divers provide a SPATA certified swimming pool leak detection service to discover the cause of swimming pool leaks

Mains Water Leaks

Water main leaks can manifest as an internal or external water leak. A unusually high water bill is a sign of a leaking water main. The single most likely location of a water main leak is outside where the water supply line is damaged by ground movement which causes pipes to fracture or fittings to become faulty. Our engineers complete a water meter leak test to determine if the leak is internal or external, then perform a leak detection investigation to identify the leak.

Below Ground Water Leaks

Underground water leaks develop from water supply lines, irrigation systems or drainage pipes. Causes of underground water leaks include ground movement, worn pipes, tree root damage or inadequate installations. We identify underground water leaks by initially establishing which pipes are beneath the ground. Our non invasive leak detection approach is used to locate the cause of the leak without causing damage to the ground surface.

Underfloor Pipe Heating Leaks

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

Building Leaks

Building leaks appear in the roof, wall or foundations of a building due to settlement of building materials, subsidence, faulty construction or deferred maintenance. Our structural leak investigation team identify leaks in building materials including concrete, brick and wood using a selection of leak detection methods including Tracer gas leak testing, thermal imaging and acoustic listening devices.

Flat Roof Leaks

Roof leaks vary from slight water intrusion causing damp to a heavy flow of water in heavy rainfall. Roof water intrusion appears where there are missing tiles, damaged flashing, worn mortar or damage around a chimney. Causes of leaks on roofs include storm damage, poor construction, inadequate maintenance and wear and tear as the roof gets older. Discover the source of your roof leak by choosing our extremely skilled roof leak investigation team.

Bathroom Leaks

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

Drainage Leaks

Drainage leaks happen on internal and external drain pipework. Causes of leaks on drain pipes include damaged pipes, worn seals, blockages, loose connections along with tree roots and ground movement. A drainage system is not under pressure so leak detection approaches are limited to CCTV surveys inside the pipe. Our drainage engineer provides a detailed inspection to detect the cause of the leak and are typically able to carry out a repair on the same day.

FAQ - Leak Detection in London

Do you guarantee to find my leak?

No leak detection company can guarantee detecting all leak. However, we deliver a No leak-No charge service for water main leaks on individual properties where the supply lines are shorter than 30 metres long and losing more than 30 L per hour.

Will locating the leak damage my property?

No.. Our non-invasive leak detection methods will not damage your property. In some cases, we may need to drill a tiny 5mm hole into a cavity for camera access. No matter where the leak's location, minimal damage could be essential to access and repair it.

Will you isolate the water while leak detection?

We generally won't need to turn off your water supply during leak investigations. Nevertheless, we may need to shut off the stopcock temporarily when conducting repairs.

How long does it take ?

Leak detection generally takes between a couple of hours and a full day or longer. The time necessary to identify the leak source depends on the leak type, its location, and the complexity of the investigation.

Will you repair my leak?

Yes. We will repair plumbing leaks on the same day as detection, provided our engineer has available time after detecting the leak. Repair charges apply additionally.

Can you support me with my insurance claim?

Yes. We deliver insurance-approved reports for claims purposes. If your home insurance features "Trace and Access" cover, you can get back the leak detection costs.
