The quality and cleanliness of the work was very good, a competence in the subject areas, as you unfortunately do not find so often nowadays. Simply friendly, polite and fair. A company that still seems to do its work with heart and mind, which is also evident from the whole demeanor of Mr. Blattert. I also had the hygiene inspection of my drinking water pipes and the storage tank carried out, although at first I did not know exactly what it was good for. But now I can only recommend this to everyone, because not only Corona, but also the Legionella can become dangerous to us. Summarized in an expert opinion (probably called a hazard analysis), it was clear to me what I needed to have fixed first. Now I am happy about the clean drinking water in the house. Here also still fits the price-performance ratio, even if the prices are in the upper segment - the performance fits.
