Frequently asked questions

Why do we offer this for free? Because roughly half of the concerns vanish during the inspection - and we would rather look into your pipe early than pump out your basement later.

What does the free sewer inspection cover?

A Greentech technician drives a TV camera through your private wastewater pipes and checks them for deposits, limescale, root ingress, standing water and visible damage. You receive the recordings and a plain-language report showing whether action is required - or whether everything is in good shape.

Is the inspection really free?

Yes - CHF 0.-, no follow-up job required. It is how we win customers who already know us when they need a sewer service later. If we find something, you receive a written quote. Whether you accept it - from us or from another provider - is entirely your decision.

How long does the inspection take?

The on-site TV camera inspection usually takes around 30 minutes. You then receive the recordings and the report, explained in plain language and without jargon.

In which regions is the free sewer inspection available?

We offer the free sewer inspection in the cantons of Zurich, Aargau, Thurgau and Schaffhausen. Our team dispatches from Schlieren ZH - simply sign up via the form and we confirm the appointment.
