Professional water leak detection involves the use of specialist equipment to locate hidden leaks.

A leak detection company will be needed if a plumber has been unable to find the source of a leak.

Common types of leak detection equipment include:

• Infrared cameras

• Acoustic listening and correlation

• Tracer reels and utility trackers

• Moisture metres

• Pressure testing kits

• Fluorescent dyes

Not all water leak detection companies in W4 use the same equipment and methods. We recommend asking for details of the tools and testing methods used to find the right company for your needs.

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 W4.

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.

Often a water leak detector won’t know exactly how long the test will take until they arrive at your home.

That being said, a water leak detection test usually takes approximately half a day to complete.

The duration of the work will be longer if the pipes can’t be easily accessed.
