How we identify and repair leaks

Leaking pipes repaired
Why do we believe our engineers are the best?
When called out to a leak or suspected leak our engineer will assess the problem and decide upon the safest and most effective method of repair.
We may use CCTV drain surveys to address the root of the problem, providing real-time footage of the drainage interior. This will allow us to pinpoint any cracks, blockages, or leaks.
Pressure testing can also detect leaks. By pressurising the drainage system, drops in pressure can be located and often will point to leaks or weak points.
We employ various methods of leak repair, though the exact method will depend on how severe the leak is.
Patching drains with minor leaks will often be enough to get them in proper working order. However, for tougher leaks, it may be appropriate to reline a drain with a flexible lining inserted into the existing pipe.
Failing this, we may undertake a drain excavation to replace the affected area with a new drain pipe entirely.

For your peace of mind we aim to attend all leaks within a 2 / 3 hour window to get you back in your flow.

Residential - How to spot a leak

We support domestic households in providing drainage solutions, and often it can be tricky to know if a leak has occurred. Here are some ways to tell:

 Water stains or puddles 

Check the area around your drains, especially under sinks, toilets, and shower/bathtub areas, for any water stains or puddles that appear even when the fixtures are not in use.

 Musty odours 

Persistent musty or unpleasant odors near drains can indicate standing water or leaks within the drain system.

 Slow drainage 

If water takes longer than usual to drain from sinks, bathtubs, or showers, it could be a sign of partial blockages caused by leaks or damaged pipes.

 Mould or mildew growth 

Excessive moisture from drain leaks can promote mould and mildew growth on walls, floors, or ceilings adjacent to the drains.

 Unexplained increase in water bills 

A sudden spike in your water bill without an obvious reason may indicate a hidden leak within your drain system.

 Discolouration on walls or ceilings 

Yellow or brown stains on walls or ceilings, especially around drain pipes, may be indicative of water leaks.

 Unusual sounds 

Gurgling or bubbling noises coming from drains when using water fixtures may suggest a leak or air escaping from damaged pipes.

Frequently Asked Questions
When should I have my drains assessed for leaks?

If you are concerned that your drains are leaking, you should call Grey-Water immediately. The integrity of your drainage system should be maintained at all times so if you suspect a leak, action must be taken. Aside from any immediate concern, it is wise to have your drains inspected regularly to prevent leaks in the future.

How long does it take to repair a leak?

Depending on the size and location of the leak, the repair time can take as little as a few minutes, or as much as a few hours. It may be as simple as patching a leak or employing a flexible liner, but if a leak is rather large or points to further corrosion of a drain, it may need to be excavated and a section could be replaced altogether.

How much does drain relining cost?

The sum total of our relining operations is dependent on a number of factors, such as the extent of the damage that is causing the leak, where it is located, what method is needed to fix the problem, and how long it takes to fix. Our rates generally start at £60.

Do I have to pay in advance for leak repair?

Due to previous experiences, we ask for payment in advance of leak repair once the problem has been identified.

Will any damage be done to my drains whilst a leak is being repaired?

We will never damage your drains when carrying out repairs of any kind. We use state-of-the-art equipment handled by fully-trained professionals to see to the repair or sealing of any leaks in your drains.

Is there a local leak repair service near me?

If you live in the Kent or London area, we have local operatives in your area. We are available to carry out commercial and residential leak repair, depending on what you require. Give us a call and we will provide you with our next available visit date.

Can I repair a leaking drain myself?

Due to the specialist training and equipment needed in order to repair a leak present in a drain, only experts are qualified to undertake this task. With the complexity of some drain systems, and without a proper survey being carried out beforehand, there is no way to know how the drain looks, or how to navigate it in order to locate the leak.
