We only have positive feedback about the company 4 Okna. We were recommended to use their services by acquaintances who are also satisfied with their work. After reviewing the offers on their website and consulting with a representative, we called in a technician to take measurements for our future window. We have a slightly non-standard wall and thought we would have to order two separate windows, but on the technician's advice, some light construction work was done, and we ended up with one solid window made of two parts. A couple of days later, the windows were ready, and they were installed quickly. But the best part was that after the work, the technician removed the old window frame and all the debris that appeared during the process. It's a small thing, but very nice...
