Von sehr speditiver Kontaktnahme nach Anfrage bis Offerte und Arbeits-Umsetzung können wir Fa. Riedwyl als sehr kompetent und zuverlässig bestens empfehlen. Die Monteure haben in sehr beengten Platzverhältnissen zur Montage der neuen Speicher-Isolation aufgrund eines Leitungs-Wasserschadens ihr bestes gegeben; super. Sie sind auch kreativ, denken bei der Arbeit mit und wir erlebten sie als sehr angenehm. Ganz herzlichen Dank der ganzen Crew. Fam. Hug
