Sterk Kozijnen B.V.

Top quality PVC windows! They look beautiful and the installation is professionally done in perfection. Highly recommended Sterk Kozijnen for top quality products with the best prices! Thank you Bekir.

I got front door and several windows from Sterk Kozijnen. They gave me very good advice on windows and provided very reasonable prices. Installation was done quickly and with good quality.

Unfortunately we were really ripped off by the owner Bekir, warning never pay in advance! He has such nice talk, but it remains talk! The owner Bekir has ripped us off badly after we ordered and paid for window frames for the entire house! He is really an amateur and has placed a dormer window at our house that was not done properly at all! And has to be done all over again! He also placed 5 window frames and 2 small windows of which he destroyed all our walls and left the window frames like that! This man made an appointment with us and received more than 30 thousand euros for the window frames and dormer window and the sliding door for our extension! He was supposed to start the renovation at the beginning of May, but after he received the payment he went on holiday for 10 days without consultation while we had discussed this job urgently! After he came back he took on all kinds of other jobs in between and he left us hanging again! And was not reachable for a few days! Then he placed the window frames with great difficulty, and it was really a nightmare! Everything was crooked and damaged! The handles of the frames could not be opened, and when you spoke to him about it he was silent. He also never ordered our sliding door that we paid for!, and our dormer window frames were never delivered. And when you ask where the sliding door is after 5 weeks he ignores you and simply does not answer! I am going to take legal action because I have been seriously scammed! In the end Bekir (the owner) blocked me and is sending fake invoices that I still have to pay, in order to get out of it! People please think carefully there are so many professional companies! This man works alone and has inexperienced staff who come to help him and who really do not know what they are doing! I will also share photos of the damage he caused to us! And unfortunately we still have not received our sliding door worth € 6000 and our dormer window frames worth € 4000 and our skylight! And he blocks so easily he does it!

The first job was to replace the garage door with an entire facade. First experience and the other 2 are absolutely great. I am very critical and look for expertise, communication, timely delivery as agreed, trust, but also think along with your wishes. His advice is always right and if you are not satisfied after installation, he will ensure that you are very satisfied free of charge. In the event of unexpected setbacks, it is never at the customer's expense. We will definitely come back to bekir van strong window frame for our next order. Oh yes, he also always works very hard with the other people, ensuring the quality of the installation. Keep it up!

Very satisfied with the replacement of our window frames! We recently had our entire house fitted with new plastic window frames and are extremely satisfied with the result. From the first moment of contact, everything went professionally and pleasantly. Agreements were neatly fulfilled. The staff was friendly, thought along with us and worked neatly. The quality of the window frames is excellent; you can tell that they work with solid materials. The finishing is also taken care of down to the last detail. In addition, we found the price very fair for what we got in return. All in all, a reliable company that we would definitely recommend to others!
