We recently renovated our windows and doors with HR+++ glass using KozijnBase and we are extremely happy and satisfied with the results. From the very beginning, the communication with Burak through WhatsApp and email was exceptionally fast and clear. Burak was always quick to respond and even offered us the best solutions based on our needs. The installation team was highly professional, neat, and organized. They worked with great care and attention to detail throughout the entire process. Their dedication and high-quality workmanship truly deserve a 5-star from us. Thank you KozijnBase and team for everything. We are very pleased with the outcome and highly recommend this company to everyone.

I installed new PVC windows with HR+++ glass at my house in November 2025 done by KozijnBase. The entire experience was very positive, from the first contact and quotation to the final installation. Mr.Burak was great in clear communication and overseeing everything. The work was completed on time as promised, with excellent workmanship and a high-quality finish. They handled everything professionally, including all finishing work and cleaning. They even did extra work by removing and installing a new heater to accommodate a larger window. I’m very happy with the service and the final result, and I would definitely recommend KozijnBase.
