In our long and vast experience, we find most blocked drains are cleared within half an hour.

CCTV drain surveys for your blocked drains

CCTV drain surveying for blocked drains
This image shows a CCTV survey being carried out for a blocked drain clearance.

Our CCTV drain survey technology allows us to carry out an in-depth and accurate drain inspection. Using CCTV drain cameras, we can easily 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 has been cleared.

Once your engineer has carried out the drain inspection, they can provide you with a DVD copy, but this must be requested before the inspection occurs. This service is beneficial should you need evidence for insurance purposes.

Our team will then recommend 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 hight-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 drains by descaling the pipes

A build-up of limescale is one of the many causes of blocked drains and can significantly affect the functionality of your drainage system. Using high pressure jetting, we can eliminate any stubborn blockages to return your drainage system's natural flow.

We also provide professional maintenance for your blocked drains.

This includes regular visits to your premises on a planned basis to maintain your drainage system. By booking regular blocked 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
  • Houses with a drain problem waiting to be fixed
  • Restaurants
  • Fast food outlets
  • Schools
  • Food processing plants
  • Industrial estates
  • Retail parks and individual industrial/retail units
  • Hotels and guest houses
  • And more
