Ulrich Althoff GmbH

We had new windows and a new front door installed by Althoff. The staff on site were really very friendly. The work was carried out cleanly and quickly. The consultation was also excellent. We are very satisfied.

I can highly recommend them. We had a wooden door made and installed by Althoff in 2022. They kept to the schedule (which isn't standard practice these days), the installation was clean, and there was good communication between the customer and the installer. Yesterday, someone came for the first time to adjust the door. Everything was explained to me in detail, so I can adjust it myself next time if necessary. Wooden doors do expand and contract with the weather, and they settle a bit over time. But the service went even further; they also adjusted the windows that were installed by another

Large wooden balcony window and door replaced with a plastic one. Excellent and clean work. Ordered another window.

The consultation and installation of the custom-made hallway furniture in our new apartment by Mr. Kahlert and the other employees of the Althoff carpentry workshop were exceptionally professional. Our wishes were taken into account in every respect during the initial consultations. We thank the Ulrich Althoff carpentry workshop for their outstanding craftsmanship!

We got new windows and patio doors throughout our house and are delighted with them every day! The general advice on soundproofing, insulation, and burglar protection, the recommendation for casement windows to match our existing building, the clear quote structure and invoice, and, of course, the very friendly and professional team during installation, all contribute to an absolutely positive review of the company. The price-performance ratio is 100% right! Great work, thank you very much!
