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. The company communicated and draw up a contract and quickly responded to the new requirements. The initiation and the termination of the exchange of plastic windows was done exactly according to the established deadlines. What concerns themselves work, the focus of the windows was done flawlessly performed by Mr. Tomáš Plšek.  Mr. Tomáš Plšek with his installation crew conducted a professional exchange of windows ( really very high quality mason work). The company communicates itself, inform us about the delivery of the manufactured windows on the warehouse. Mr. Tomáš Plšek contacted me a week in advance and we confirmed date of start of work.

In today's time, there is sometimes Art to choose a really quality company. I highly recommend the RI WINDOWS a.s. Company. I'm sure you'll be satisfied and happy.

Once again to all who participated in the exchange of our windows, thank you very much.
