The company impresses not only with the quality of the windows but also with the level of service. During my first call, after I explained my expectations for the window upgrade and provided the sizes, the manager Dmitry advised me to order plastic windows with a 6-chamber Wital profile. But what surprised me the most was that the approximate price mentioned by Dmitry matched what the measurer quoted. I don't remember ever experiencing something like that before. That's what it means to be a pro.
