Super nice staff and, unlike many tradesmen, delivered very clean work! Punctual, friendly, helpful and top professional!
I would have liked to have had a few of them on my building site, then things would have gone faster and more professionally!!! ;)

As already written in an email after the installation of the basement windows, the clean working method should be particularly emphasized. Despite breaking out the old windows and then installing new ones, the amount of dirt was manageable and the rooms were left clean. Reworking the windows (frames) was hardly necessary

Employees showed competent, relevant behavior. Queries were always answered professionally. The installation of straight window elements went smoothly, but there were problems with arched windows.

Recommendation
We had to replace a patio door and a floor-to-ceiling bedroom window with two movable sash elements at the top and two fixed elements at the bottom in our 22-year-old apartment. Following a telephone inquiry, the customer service team came at short notice to view and measure the situation on site. The employee gave us good advice on the additional insect screens we wanted, especially for the solution with a swing door on the patio door. The quote arrived by post a few days later. We had obtained another quote in advance so that we had a price comparison and placed the order with Müller.

We were informed of the expected calendar week for implementation with the order confirmation. The deadline was ultimately pushed back a little, but as we were under no time pressure, this was not critical. We received a detailed information sheet from Müller for the necessary work, so that we were able to prepare the premises and access points well. The employees were on site punctually on the agreed date and carried out the work quickly, professionally and cleanly.
We are very satisfied with the implementation of our order and the quality of the installed elements and are very happy to recommend Müller to others.

Overall very good impression in terms of advice and professionalism of execution.
Unfortunately, there were some weaknesses in the transfer of the finally agreed offer to the AB (a window was forgotten) and in the installation with regard to the complete insulation between the window frame and the wall (had to be reworked in one case)

Dear customer,
Thank you very much for your feedback. We are pleased to hear that you have a very good overall impression of our advice and the professionalism of the workmanship. However, we regret that there was an error when transferring the final agreed offer to the order confirmation and that a window was forgotten. We also regret that there was some reworking during installation. We take your feedback very seriously and will work to avoid such errors in the future. Thank you for bringing this to our attention and we hope that you are satisfied with the final result. Best regards, Martina Callari on behalf of the management of Müller+Co

They look for and find solutions even for tricky cases. Processing and documents 1A. Any time again. Perhaps not the cheapest provider, but you have peace of mind.
