Extremely frustrating from start to finish. Promises were made confidently at the beginning, but almost none were kept. Delivery timelines kept shifting with no clear explanation, and communication became increasingly difficult. This has been a costly and stressful mistake.

Absolutely unacceptable experience

Absolutely unacceptable experience. After paying a significant upfront amount, the service quality dropped instantly. Endless delays, vague answers, and zero accountability. It feels like once they have your money, you are no longer a priority. I strongly regret choosing this company.

We had seven windows and the balcony door replaced in our old apartment in Spandau-Haselhorst. Everything went very professionally, from the initial measurements to the installation. The installers were punctual, worked cleanly, and left the area spotless. A particularly positive aspect was that the delivery time was shorter than expected. The price was fair for the quality received. We highly recommend them to anyone planning a similar project in the area.

After a long search

After a long search, we chose Deutsche Fensterbau and haven't regretted it. Our house in Rudow now has nine new triple glazed uPVC windows, and the difference in noise levels and heating is enormous. The team completed the installation in two days, which I wouldn't have thought possible. The only thing that could be improved was their telephone accessibility, at least on the day of installation. Overall, though, it was a very good experience

I obtained quotes from three different suppliers and immediately realized during my phone call with Deutsche Fensterbau that they really knew their stuff. They explained the differences between the profiles and glazing to me without using technical jargon and advised me against a more expensive option that would have simply been overkill for my needs. That inspires confidence. In the end, I got exactly the window that fit my budget and requirements.

Offer and advice very good

My inquiry was answered within 24 hours, and I received a detailed quote with various configurations the same day. The consultant in the office took plenty of time to answer all my questions, including on topics like sound insulation classes and available subsidies. I'm satisfied.
