CCTV drain surveys for your blocked drain
Our CCTV drain survey technology allows us to take a quick look or an in-depth and accurate drain inspection. Using CCTV drain cameras, we can quickly identify any structural damage or defects to the pipes. If we discover a blockage or another issue, we can then provide an appropriate solution. We can also use the camera to assess what caused the blockage after your drain is cleared.
Once your engineer has carried out the drain inspection, they can provide you with a DVD copy, but you must request it before the check so we know we are recording it for general view. This service is beneficial should you need evidence for insurance purposes.
Our team will then recommend the methods required for any remedial work that may be needed.

Drain jetting for thorough blocked drains clearance
Drain jetting is one of the most powerful and effective ways of clearing your blocked drains. If you would like to know more about our high-pressure drain jetting services, visit our drain jetting page or call our team today to arrange a call-out.
Clearing your blocked drains of roots
Root regression in drainage systems is common and can cause significant drain blockages.
To clear the roots from your blocked drains, we cut away roots that have penetrated the pipelines using our root cutting equipment. By cutting away and eliminating the tree roots, we help clear your blocked drains. However, if the tree roots have grown through the pipe to the extent where the pipe becomes irreparable, we may have to replace the pipe's affected section.
Clearing your blocked drain by descaling the pipes
A build-up of limescale is one of the many causes of clogged drains and can significantly affect the functionality of your drainage system. We can eliminate any stubborn blockages using high pressure jetting to return your drainage system's natural flow.
We can also provide professional maintenance for your drains.
This includes regular visits to your premises on a planned basis to maintain your drains and prevent them from getting blocked. By booking regular drain maintenance, you can avoid costly future repairs caused by blockages due to fat build-up, tree root ingression or other obstructions in your drainage system.
We undertake planned blocked drain maintenance for:
- Domestic drains with insufficient fall
(prone to a blocked drain due to fat in sitting water build-up). - Houses with a known drainage problem waiting to be fixed
(a known blockage attached to a private sewage system may need regular attention until the customer is ready). - Restaurants
(prone to blocked drains from fat & grease build-up). - Fast food outlets
(prone to blocked drains from fat & grease build-up). - Schools
(prone to blocked drains from tree debris washed into gullies). - Food processing plants
(prone to blocked drains from fat & grease build-up). - Industrial estates
(prone to blocked drains from multiple occupancy build-up). - Retail parks and individual industrial/retail units
(prone to blocked drains from public misuse of toilet system, e.g. wipes). - Hotels and guest houses
