I needed to replace 7 windows in my home which can be an overwhelming task. So many window companies to choose from and then there is the material that the window is made of and there is the style, colour etc. I finally chose Ecoline and I am so grateful to their sales representative Sergey. He explained in great detail the construction of the window and the pros and cons of what I was looking for. The price was reasonable and was in line with other competitors. The window installers were great. Petro was very efficient and knew his trade. No time was wasted to install the windows. Everything was cleaned up after the install of the windows. Since the install of the windows I am finding less street noise filtering into the house, the air conditioner is not coming on as much which means I am very happy with the windows, I chose. The test will come this winter and I will keep you posted whether the windows meet my expectations.
