INTERwindow GmbH

I am absolutely thrilled with Inter Window's service! After contacting them about a broken door handle, I received immediate and straightforward assistance. The necessary replacement part was quickly and even sent free of charge as a customer service gesture. This is truly an outstanding example of customer focus and professionalism. I wholeheartedly recommend Inter Window and would like to thank them again for their excellent support!

Simply top-notch – thank you to Klaus Hintersonnleitner for the excellent advice and the quick, straightforward window replacement! A big thank you also to the installation team, who worked in a friendly and clean manner (including using carpets to cover dust, etc.) and expertly replaced even the trickiest old windows. Looking forward to working with them again in 30 years, and keep up the great work! 💪👍

We were very satisfied with Interwindow's work, quality, and workmanship. From the initial consultation to delivery and installation, everything was top-notch! Very competent and friendly salespeople and installers. Highly recommended!

We were very satisfied with the entire process, from the initial quote to the completed work and invoicing. The installers worked very cleanly and quietly. I was delighted that the entire renovation was carried out without any mess. I can highly recommend this company!

You can rely on this company. Punctuality and the professional and friendly advice from Mr. Weiss-Entholzer. What particularly impressed me were the installation workers (Leopold). They were on time and left the construction site clean. That's how it should be! Best regards, the Wagner family
