Soil Stack Blockage Clearance

What soil stack blockage clearance covers

Soil stack problems can be messy and disruptive, so the aim is to restore safe, reliable drainage as quickly as possible.

• Assessment of symptoms and likely blockage location
• Safe clearance using the most suitable method for the pipe and access available
• Checks to confirm normal flow has been restored (flush and drainage testing)
• Identification of contributing causes (for example, wipes, fat build-up, scale, debris)
• Practical advice to help prevent repeat blockages

When this service is most useful

This service is a good fit if:

• Toilets are slow to flush, bubble, or back up
• You notice persistent sewage smells indoors or outside
• Multiple fixtures are draining slowly (especially on lower floors)
• There has been a recent overflow, leak, or staining around the stack
• You manage a rented property or small premises and need the issue resolved quickly and properly

How the clearance is carried out

The visit starts with pinpointing where the restriction is and what is likely causing it. The blockage is then cleared using appropriate equipment for the job, with care taken to minimise disruption and mess. Before finishing, drainage is tested to confirm the stack is flowing normally, and you will be told what was found and what to watch for.

After the blockage is cleared

If the stack clears but there are signs of an underlying fault, such as damaged pipework, poor falls, or recurring build-up, you will be given clear next steps. Where further work is needed, options are explained before any additional work goes ahead. You will also receive simple guidance on what not to flush and how to reduce the risk of another blockage.
