Knoll Heizung-Sanitär GmbH

A down-to-earth and professional company. I have used this company for the second time and I am very satisfied. The work is carried out cleanly and you can rely on the staff 👍. Can only say top👍👍

Friendly, down-to-earth and, above all, customized service, on an equal footing, on site. Quick information, good preparation for eventualities and competent advice in one. Top!

Office not occupied due to Corona. Therefore Bad customer service.

During the core renovation of our house, Knoll installed the bathrooms and a new heating system. Everything went well - communication with other trades was good, so there were no major delays

Company remains on the problem and seeks solutions much better than the competition .. like again
