About us

Our history started in 1994, when Pirmin Donauer established Donauer Heizungsbau. Given the young company’s great success and the constantly increasing business, Christopher Probst joined the newly founded Donauer & Probst Rohrsanierung GmbH & Co. KG as Commercial Director. With a workforce of currently more than 20 employees, Donauer & Probst has since then been able to continue its success.

Co-operation partners and licensees in Finland, Austria and Switzerland offer our services in a European context. As an initiator and driving force of the Verband der Rohrinnensanierer Deutschland e.V., the company actively supports the definition of standardised technical regulations in the area of internal pipe repair.

Pirmin Donauer, Technical Director


“We attach great importance to execute orders correctly and on schedule and to realise our projects efficiently and without problems for the customers. The ideal situation would be, if they don’t see us when we are there – but only see that we have been there.”

Christopher Probst, Commercial Director


“We decided to have our company certified to ISO 9001 in order to point the way to the future. We want to show our customers that they can rely on us. In this context, our 5-year warranty for internal pipe repair work is only one element.”
