We are very pleased with the windows, manager Svetlana is above all praise, she clearly explained the advantages of a particular material, window sills, handles, etc. The measurer and Installers did their job promptly, everything on time without delay, and a product warranty is also provided. At the same time, the price difference with private companies is insignificant, there is no point in taking risks because we choose windows for many years. I recommend this company!
