We purchased our “retirement” fixer upper near Dorset Ontario. The first project we tackled was all new windows and doors. We chose to go with Ostaco because they were able to customize our order and had the quality we were looking for. The sales rep made some great suggestions including using different LowE coatings on different elevations of the house to maximize energy efficiency. What a difference, the house is always comfortable and we have noticed a big difference in our heating and hydro bills. The new windows and doors have completely transformed the look of our house, we frequently have people stopping to ask where we got our windows and doors. I wouldn’t hesitate to recommend Ostaco windows, it has been the best investment we have made in our home.
