Are drainage companies trustworthy?
Our experience of drainage companies over the years hasn’t been good.
On more than a few occasions, we’ve seen some of these firms claim that the drain can’t be jetted and it that needs to be replaced or relined.
We don’t want to tar every firm with the same brush as there are many occasions when a drain could be damaged and require relining or replacement.
However, we suggest consumers choose their plumber or drainage company carefully and preferably via a trusted recommendation.

Price 3 – CCTV Drain Survey Cost
Drains are occasionally blocked by something that can’t be flushed out, for example, root ingress, a cracked or collapsed pipe or similar.
The only way to determine the cause of the problem is to send a small camera down the drain and assess the pipe’s condition.
A price for further work can then be given to the customer; this could be for pipe relining, pipe replacement or something similar.
Drain camera surveys aren’t always needed but could be required if the company cannot clear the drain blockage or the drain blocks again soon after being jetted.
The CCTV drain survey price below is for a basic survey of a single troublesome drain. It doesn’t include the cost of mapping or inspecting all of the drains for a property.
|South, SW and Midlands||£95||£130|
|Outer Region and North||£75||£100|

How Long Does it Take to Unblock a Drain? What Work is Involved?
Here is a typical works schedule that a drainage company will complete when they visit the property:
- The pipework is first inspected to determine who is responsible for the blockage. It could be the water company, a neighbour, or several homeowners if the pipe is shared (i.e. flats/apartments).
- The drain is then jetted with water to clear the blockage.
- The main drain is then checked to ensure that the freshwater being used is entering the main sewer.
- The area is then cleaned, possibly with a disinfectant if required.
The work normally takes around half an hour but drains that are not easy to access could take longer.
What Tools Are Used?
Most drain unblocking experts will have water stored in their van which is put through a very high-powered pump to clear the drain, via a specialist attachment.
These jets are far more powerful than the typical pressure washers you may find for sale online.
Also, the jets are attached to flexible hosing so they can go around bends in the pipe.

Can Drains Be Unblocked DIY?
There are several options for those wanting to unblock their drains themselves.
Although not the cheapest, the easiest option is to buy (or perhaps borrow) a pressure washer and connect a drain cleaning attachment.
Here is a YouTube video explaining how it works.
The process is fairly simple, but please wear gloves!
If you don’t have access to a pressure washer, try the old fashioned way of unblocking drains – by using rods.
These rods effectively push blocked waste through the pipe where you can pull it out at the next section or push it through to the main sewer, which is larger.
Rods are easy to use, they come in one-metre sections so are perfect for long sewage drains in the garden.
Just be careful not to lose a section in the drain and wear gloves.

My Drain Keeps Blocking, What Can I Do?
If the drain keeps blocking, even after being cleared, it could be due to these reasons:
- A cracked or damaged pipe.
- Collapsed pipe.
- Root ingress.
- You’re putting the wrong items into the drain, i.e. sanitary or wet wipe towels etc.
- The drainage pipe is incorrectly installed.
- A problem in the street’s main sewer or a lateral drain is causing a blockage to back up into your drains repeatedly.
Solutions range from changing what you put into the drain, replacing or relining the pipe should it be cracked to installing filters in the sink/shower etc. to stop hairs/food entering the pipe.
Who Is Responsible For Blocked Drains in My Garden?
The homeowner is responsible for blocked drains within the boundary of the property unless they are lateral drains.
All drains on public land are the responsibility of the water company, as are any laterial (shared drains) on private land.
