Having invited representative for a free quote in house, I got all the answers on my questions. I am not that professional in windows technology but was described with all possible options that a window might have.
I used to compare 3+ quotes and not less. Spending some time on that I came to Award Windows and happy on that.
Since I ordered 5 windows I got a reasonable good discount. As a result, ordered windows were replaced fast by highly qualified team. I talked to them, they are super friendly and always ready to make advances. The biggest impression is that they treated me as a really valuable customer and I am sure if I need any other door/windows installation I will definitely contact them; that I actually planning to do for my next reno stage.
Fully satisfied, replacement was done just perfectly.
