More information

What commercial drain unblocking covers

Commercial drainage problems can affect hygiene, staff welfare and day to day trading. This service is designed to restore normal drainage quickly and leave you with a clear understanding of what caused the issue.

  • Clearance of blockages in internal and external drainage serving commercial premises
  • Removal of common causes like grease build-up, scale, silt, wipes and foreign objects
  • Unblocking of toilets, urinals, basins, kitchen sinks, floor gullies and waste pipework
  • Jetting or mechanical clearance methods selected to suit the system and the blockage
  • Optional CCTV inspection to locate the problem, confirm clearance and identify defects
  • Flow and function checks before completion
  • Practical recommendations to reduce the risk of repeat call-outs

When this service is most useful

Use commercial drain unblocking when you notice slow draining sinks, recurring toilet issues, gurgling, bad odours, or water backing up from floor drains or external gullies. It is also suitable when you have a busy site and need the problem resolved quickly, with clear updates for facilities teams, landlords, or managing agents.

How the service is delivered

You will be asked a few quick questions to understand symptoms, access points and any previous issues. The drainage run is then assessed on site, the safest and most effective clearance method is selected, and the blockage is removed. If the cause is not obvious or problems keep returning, a CCTV check can be used to pinpoint issues such as pipe damage, poor falls or root ingress.

Aftercare and ongoing prevention

After unblocking, you will get clear guidance on what to change or monitor to prevent a repeat issue, for example grease handling, correct waste disposal, or routine cleaning. Where needed, you can arrange planned maintenance jetting or further investigation to address underlying defects rather than repeatedly treating the symptom.
