When I decided to replace my old windows in my quest and bedroom, my friend recommended Oleg for this job. I called him and next day he came to my place to make some measurements,and told me that he was going to call me next day to tell when the windows are going to be ready. After that we set a day, when the job had to be dun. He came with his helper, they did the job in a fast, accurate manner and I had not even clean after them. Those windows he installed in my house showed very good performance during winter time and plus they were Energy Star rated and Oleg advised me to apply for Energy Saving Program and Home Renovation Tax Credit. So I got some money from the government.
Thank you very much, Oleg.
