Common signs of a hidden water leak include:

• Increased water bills

• Water stains on walls, floors and ceilings

• Mould and mildew growth

• Unpleasant ‘musky’ smell

• Damp patches

• Drops in boiler water pressure

• Pipe corrosion

• Puddles on the ground around toilet, taps, baths and sinks

• Wet patches in the garden and on the drive (during dry weather)

Finding and fixing a leak will prevent further water damage to your property. Fixing a leak as soon as possible will also save you money on water bills in the future.

If you have spotted the signs but don’t know where the water is coming from, it is time to hire a water leak detection company in London.

Leaks can occur anywhere where water is present both inside and from outside the home. Some of the most common places for a water leak are:

• Taps

• Shower hoses

• Bath, shower, and sink drainage

• Washing machines and dishwashers

• Flat roofs

• Boilers

• Radiators

• Toilets

This depends on the size and location of the leak. If you have a small leak that you can’t fix yourself, but you can collect the water in a container to prevent damage, then the leak is not an emergency.

If water is leaking at force and you need to turn off the water supply at the mains, you’ll need to call an emergency plumber.

Water detection equipment often works by monitoring the flow of water through a pipe.

Acoustic sensors can recognise any unusual noises which may indicate a leak and help to identify its location.

Water leak detection tests are often made up of two stages: trace and access.

During the trace stage, a leak detector will aim to use non-intrusive methods whenever possible to test your property’s pipework for leaks. For example, an infrared camera or fluorescent dye may be inserted into the pipes.

Occasionally intrusive methods such as drilling and digging will be needed for the test equipment to be used correctly.

Once the leak has been detected your tradesperson will move onto the access stage. This part of the test involves repairing the leak.

Depending on the extent of the damage, you may choose to hire a plumber to do this work for you instead.
