Yes we can! However, we may need to carry out minor excavation works to expose it before we repair it.
To avoid further problems arising, the area must be dried once the leak has been repaired. Moisture generally traps itself within surface’s even if you can't physically see it. If the property has not been dried after a leak, mould and further damage will appear in the décor of your building. This will also cause health implications when mould is taken in via the lungs, which can seriously cause issues to your health.
There are several ways of testing this one of which is to turn off the stop cock for the water feed running into your property. Check to see if the meter gauge is still running then this is a clear indication here is a suspected leak on your side of the property. The stop cock is either located underneath your kitchen ink or alternatively under your stair cupboard. Another form is to look out for sudden damp patches appearing in certain sections of your property.
There are two types of stopcocks that control the water supply to your property. The first is the external mains stopcock, which connects your property to the main water supply from the street - this is usually managed by your water provider. The second is the internal stopcock, which shuts off the water coming into your home from the mains. It’s typically located under the kitchen sink or beneath the stairs.
There are a few reliable ways to check for a potential water leak. One common method is to turn off the stopcock that controls your property's main water supply, then observe the water meter. If the meter continues to move, it’s a strong indication that there may be a leak within the system.
The internal stopcock is usually located beneath the kitchen sink or inside a cupboard under the stairs. Additionally, unexpected damp patches on walls, ceilings, or along skirting boards can also be a clear sign of a hidden leak.

Unfortunately, some leaks will inevitably cause damage - but there are steps you can take to help minimise it.
The first and most important action is to turn off the water supply to your property. If you can, also switch off your boiler to prevent potential damage if the pipework runs dry.
If there’s standing water, begin drying it out as soon as possible. For smaller amounts, using a mop or towels can help prevent further spread and reduce the impact on floors and furnishings.

Studies show that the average household can lose between 2,000 and 20,000 gallons of water each year due to leaks. That’s why no leak—no matter how small—should be ignored. Even a minor drip can waste around 20 litres of water every hour, leading to significant water loss over time.
This could be a sign of a leak - potentially one that has been present for some time. For a quick way to check, refer to our answer above: “How do I know if I’ve got a leak?”
In many cases, professional drying may be required to prevent further mould growth and structural damage. Our team can carry out a comprehensive moisture survey to assess your property’s condition and recommend the most effective solution.

“My ground heating system is losing pressure”
Unfortunately, underfloor heating systems are a common source of leaks due to the large number of pipes buried beneath concrete. The layout can make detection tricky, but with our advanced equipment and experienced engineers, we’re confident in locating the source of the issue.

Check the floor above for any signs of damp. If there’s a property directly above yours, we recommend speaking with the occupant to find out if they’re also experiencing any signs of a leak.
If your property is directly beneath a roof, please refer to our advice under “Water stains have appeared in my property after heavy rainfall. What do I do?”
If the area above contains a bathroom or shower, that could also be the source of the leak. You can try a simple water test by gently running the showerhead around the bath and shower seals to see if any water escapes into the floor below.

This could be a sign of a leak on the central heating system or a problem with the boiler.
Ground source heating systems are an efficient and eco-friendly way to heat a property - but when issues arise, they can be particularly challenging. Due to the extensive network of pipes buried beneath the floor, these systems are especially vulnerable to leaks, which can be difficult to pinpoint without the right tools.
At Southern Leak Detection, we’ve successfully located leaks in many ground source systems using specialist equipment and expertise. We’re committed to finding the source - no matter how hidden it may be - because we don’t stop until the job is done.

Modern homes are typically fitted with both internal and external mains water stopcocks - so don’t worry if yours isn’t under the kitchen sink! In many properties, the internal stopcock can be found in an airing cupboard, under a bathroom sink, inside a utility cupboard, by the front door under the floorboards, in a garage, cellar, or even behind a panel near the boiler.
If you live in an apartment block, the mains water stopcock may be shared. If you're unsure where yours is located, it’s worth checking with your neighbours or building management for guidance.

If one of your radiators isn’t heating up or feels cold to the touch, it may simply need bleeding to release trapped air. However, if bleeding doesn’t resolve the issue - or if you notice other symptoms mentioned in this FAQ - it could point to an underlying leak in your heating system.
This may indicate a leak in a regular or gravity-fed heating system, or possibly from a water storage tank. If you’re able to access your storage tanks, check to see which one is actively refilling - this can help identify which part of the system is affected.
Clear away any furniture that may be positioned directly in front or underneath the water stains. Perform a visual check of
your guttering to ensure there are no blockages. This can easily be caused by leaves and other organic material. Check to make
sure that there are no drains outside the property that are overflowing. If the leak stops when it stops raining the issue is likely
to reappear during the next heavy rainfall so leak detection may still be required. The property may also require drying as the
majority of moisture is not visible and is retained within the structure of the building.

The ground source heating systems are a very efficient and environmentally friendly way of collecting heat but when they go wrong, they go terribly wrong. Unfortunately, because of the amount of piping buried under the floor they can become very susceptible to leaks, which can be extremely difficult to locate within the floor surface. We have helped various customers locate leaks in these systems with enormous success. We like a completed leak so I guess well keep looking until we find it.
