Common symptoms:
- Bad odours
- Slow drainage
- Unusual noises in the pipes
- Water backflow
A camera inspection allows us to diagnose the problem without causing any damage. Contact us for a quick response.
Preventive cleaning is recommended every 2 to 5 years, depending on:
- The age of your network
- Your usage (domestic, commercial, industrial)
Regular maintenance prevents blockages, bad odours and extends the life of your installations.
Lining is an environmentally friendly technique for repairing pipes internally without digging trenches.
A resin-impregnated liner is installed inside the pipe, creating a new watertight conduit without excavation, reducing waste and disruption.
Yes, for simple blockages (hair, grease), a plumber’s snake or hot water may suffice.
Avoid chemicals: they are polluting and dangerous for pipes and health.
If the blockage persists, our teams will respond quickly and cleanly.
A healthy drainage system prevents invisible pollution and sewage leaks.
We contribute to this transition by using:
- Clean technologies
- More energy-efficient equipment
