Water damage emergency service - basement flooded? We pump it out.
Heavy rain, backflow or a burst pipe? We are on-site 24/7 with high-capacity pumps, extraction equipment and drying gear. Typically within 60 minutes across Zurich, Schaffhausen and Thurgau. Swiss family business, no middleman.
Immediate action steps
These four steps limit the damage until our team arrives. When you call, we walk you through them.
01
Turn off the water
Close the main shut-off valve, usually in the basement near the water meter. For a single fixture, the angle valve is often enough.
02
Stop appliances
Do not run the washing machine or dishwasher, do not flush. Every extra litre worsens the backflow.
03
Cut the power
If water is standing in the basement, switch off the fuses for the affected rooms. Do not enter standing water while power is on.
04
Document for insurance
Take photos with your phone before moving anything. This helps the claim process with your building or contents insurer.
Pump, extract, dry - all from one team
With mobile dirty-water and submersible pumps we handle large water volumes and flooded underground car parks. After pumping, we vacuum residual water from floors, corners and shafts, then start technical drying so no moisture damage or mould remains. Common causes such as a blocked floor drain or backflow in the wastewater line we fix on the same visit - with high-pressure jetting up to 200 bar and a CCTV check.
On-site during heavy rain events
Thunderstorms and heavy rain regularly flood basements and garages across Zurich, Schaffhausen and Thurgau. Call us the moment water starts coming in: +41 44 500 92 05. We are reachable 24/7 and typically on-site within 60 minutes.
Insurance-ready documentation
When a water damage claim is filed, insurers ask for a technical protocol: cause, extent, measures taken, and, where relevant, a CCTV survey of the affected line to SN EN 13508-2. We supply that protocol as a standard part of every emergency intervention - written report, photos and video where a camera inspection was run. That lets you move the claim forward without waiting for another provider.

The price depends on the volume of water, accessibility and the effort for extraction and drying. You receive a quote before dispatch - no hidden costs, no middleman mark-up. For an insured event, we supply the documentation your insurer needs.
