Dear Sir/Madam

with the RI Windows a.s. company we have only the best experience. On the family  house of my parents  in Brno was changed a total of 6 French assemblys, and 4 double-hung windows. I reached out to a total of 7 companies in Brno and the surrounding area. And 5 companies sent me a quote. Clearly won in the ratio the price/quality/reviews the company RI OKNA a.s.
