Our history

The Wullschleger family business is today already in its fourth generation and has become one of the leading companies in the industry.

1. 1922

   Ernst Wullschleger sen. founds the haulage business for trading in wood and coal, back then still with horse and cart.

2. 1956

   Ernst Wullschleger jun. takes over the business and keeps developing it further.

3. 1964

   The first vacuum truck is acquired. From now on the company carries out cleaning, flushing and suction work.

4. 1980

   Rene Wullschleger joins the company as an employee and learns the craft of drain cleaning in all its facets from the ground up.

5. 1987

   Rene Wullschleger takes over the management and drives the development of the company further forward.

6. 1990

   The company dares to step into dry conveying and starts vacuuming gravel off flat roofs. This decision will shape the company lastingly in the years to come.

7. 2003

   The sole proprietorship is converted into Wullschleger Kanalreinigung AG, giving itself a modern form suited to the times.

8. 2007

   Hanspeter Blum joins the company with the long term goal of one day continuing it. Dry conveying is expanded, and the blowing up of gravel and roof substrates is now offered as well. The vehicle fleet is enlarged accordingly. By now Wullschleger Kanalreinigung AG is among the market leaders for dry conveying throughout Switzerland.

9. 2018

   Rene Wullschleger hands the company over into new hands and enters his well earned retirement. Hanspeter Blum is now the owner and managing director.
