IBO Fenster und Türen Center GmbH

The company IBO repaired our large, 10-year-old sliding patio door, which was no longer closing properly. Now it runs smoothly, better than it probably ever has! Fantastic!

They've already completed several jobs at our house. Always punctual, reliable, clean, and at very fair prices! We've also recommended them to family and friends. Everyone was very satisfied!

In July 2025, IBO successfully installed a 6 m² living room window weighing over 300 kg without any issues. They also installed a beautiful, high-quality aluminum roller shutter. Consultation, communication, service, and workmanship were all flawless. Highly recommended. Thanks again for the wonderful result.

We fitted our 1950s house with new windows (including large panoramic panes) and patio doors. After receiving several quotes from local companies, IBO Fenster's price was in the mid-range. However, the owner, Mr. Harwart, impressed us the most, both on the phone and during the on-site visit: highly competent, friendly, and above all, pragmatic – exactly what you need for a project involving an older building, where unexpected issues always arise. Delivery was prompt, and thanks to a well-coordinated team, installation was quick and very professional. They even took care of some minor tasks th

We had almost completely renovated our terraced house with new windows, patio doors, and front door. IBO wasn't the only bidder, but they won the contract because they impressed us. The result is truly more than flawless. Superb quality of the installed elements, excellent workmanship, fast, punctual, and very clean. Absolutely reliable and honest. They even did more work than agreed upon. We would use them again in a heartbeat, highly recommend them, and it's a shame there are so few such excellent tradespeople these days. TOP!!! THANK YOU to IBO and their team.
