How we unblock your drains

Drain unblocking company
When called out to a blocked drain our engineer will assess the problem and decide upon the safest and most effective method of clearance.


Grey-Water Drainage have various methods of clearance at our disposal:


For small chain cleaning machines and small internal pipe work - sinks, toilet pans, kitchen waste - we use a number of different tools including plungers, mechanical augers, chain cleaners and mini high-pressure jetting.


For external blockages such as manholes, we employ a variety of equipment including drain rods, high pressure water jetting, chain cleaners and gully grabs.


Our engineers are fully certified in high pressure jetting techniques, which is especially important in older drainage systems where clay pipe can easily be damaged by improper application of this method.


We clear 95% of blockages on our first visit, without the need for any further work or costs. 

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

It is rare we attend a blocked drain we have inadequate tooling for; it's so rare it accounts only for roughly 5% of our calls. In the majority of instances you get a first time fix, with remedial works to prevent further recurrence. Saving you money.

How to spot a blocked drain

Persistent bad smells
You may be able to smell strange or unpleasant odours from your sink, bath, shower or taps. This might indicate something trapped in your drain, perhaps decomposing.


Slow drain time

If water is draining slower than usual, this can point to a blockage. In some cases, this can cause overflow.


Noises coming from your drains

Air can get trapped in your drains and cause rumbling or gurgling sounds.


Food, hair, oil, chemicals

If you find you're shedding hair that goes down plug holes, or perhaps are washing pets in baths or sinks, this can build up and clog drains. The same can be said for food; even small food pieces can build up over time. Oil can also congeal when cooled and stick to the inside of your drains. The same type of effect can also occur when pouring away paints, which along with solvents, can harm the environment.

Frequently Asked Questions

When should I have my drains unblocked?

If you are concerned that your drains might be blocked, you should take action immediately; it may be more serious than you think. We have found all manner of debris and refuse blocking drain passages, which can lead to overflow, unpleasant smells and damage to the overall drain system.

How long does it take to unblock a drain?

Depending on the size of your property, where the blockage is situated and how much work needs to be done to remove the blockage, the completion time can take as little as a few minutes, or as much as a few sessions. It can be that there are only small pieces of debris that can be lost or flushed that block the drain, although we have also come across ingrown roots that harm the integrity of the drains and block proper water flow, which take a lot longer to remedy.

How much does drain unblocking cost?

The sum total of our surveys is dependent on a number of factors, such as the length of a blockage, the type of blockage, and how long it takes to dispose of the blockage. Our rates generally start at £60.

Do I have to pay in advance for drain unblocking?

Due to previous experiences, we ask for payment in advance of drain unblocking.

Do I need my drains unblocking?

After a drain survey, we can ascertain whether your drains need unblocking. A survey will mean feeding a CCTV camera through your drains to look for any damage or blocks.

Will any damage be done to my drains whilst unblocking?

We will never damage your drains when carrying out unblocking. We use state-of-the-art equipment such as high-pressure water jets, handled by fully-trained professionals to clean your drains and eradicate any unwanted build-up of debris.

Is there a local drain unblocking 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 drain unblocking, depending on what you require. Give us a call and we will provide you with our next available visit date.

Can I unblock a drain myself?

Due to the specialist training and equipment needed in order to unblock a drain, only experts are qualified to undertake them. With the complexity of some drain systems, without a proper survey being carried out beforehand, there is no way to know how the drain looks, or how to navigate it with a pressure washer. Talk to us today and find out how we can save you stress and money with our experienced staff.
