When the whole building is affected
If water comes up in the lower flats, or several neighbours have slow drains at the same time, the problem is in the shared pipework — not in your flat.
Shared Columns (Soil Stacks)
The vertical pipe that serves every flat.
We clear the stack from an access point and check the connection to the building drain. The lowest flats are usually the first to suffer, so we start there.
- Access from the stack
- Lower flats protected
- Flow tested
- Report for the building
Building Drains and Manholes
From the building to the public sewer.
Blockages in the horizontal drain under the building or in the manholes are cleared with high-pressure jetting. Where it keeps happening, a camera survey shows whether the pipe is damaged.
- Manholes cleared
- High-pressure jetting
- Camera if needed
- Written summary
Frequently Asked Questions
Who pays for a blocked building drain?
Shared pipes are normally the condominium's responsibility. We give the administrator a written summary of the cause and the work done.
I am a resident, not the administrator. Can I call you?
Yes. We can clear the emergency and talk to the administrator for you.
Do you do preventive cleaning for buildings?
Yes, for buildings that block regularly a scheduled jetting is cheaper than repeated call-outs.
