Dank Holzbau Zahler steht unser 94-jährige Holzhaus bestimmt noch die nächsten 100 Jahre. Die geleistete Arbeit vom längjährigen Mitarbeiter W.P. war top. Jederzeit den Fokus auf dem wesentlichen. Die Arbeite wurden genau, sauber und trotz Sommerhitze mit hohem Tempo erledigt. Ich kann die Firma nur weiterempfehlen

Unsere Katze ging es sehr, sehr schlecht und sehr schnell wusste Doktor Hofer was zu tun. Auch die Angestelltinnen konnten uns gut informieren und erklärten etwas, wenn nötig mehrmals. Grossartige Informationen auch über Telefon. Super flexibel, wir konnten zu den Öffnungszeiten nicht vorbeigehen und sie legten es in den Briefkasten, damit die Behandlung der Katze bedingungslose weitergehen konnte. Vielen Dank für die Unterstützung:)
