Guter Service, schnell und zuverlässig, fachlich sehr empfehlungswert!

Top Service. Danke

Nach der Anfrage bekamen wir umgehend eine faire Offerte. Letzten Donnerstag sind wir dann mit der Firma Fleig ins Zürcher Oberland umgezogen. Die vier Zügelmänner waren pünktlich um 7h, unglaublich speditiv, ruhig, sorgfältig und zuvorkommend. Bereits um 10h45 war alles in der neuen Wohnung, im richtigen Zimmer und im Keller. Vielen herzlichen Dank ans ganze Team. Wir werden Sie gerne weiter empfehlen.

kompetent , Freundlich und saubere Arbeitsweise

Das Team der Fa. Hasler hat uns bei der Umsetzung von unserem neuen Dachfenster super beraten, das Baugesuch erstellt und die Arbeiten sehr sauber und speditiv erledigt.

Wir haben zwei Sofas neu Polstern lassen und die Beratung wie die Aussführung waren hervorragend. Ich kann das Unternehmen nur wärmstens empfehlen!

Danke
