Our ground floor windows, purchased from Brock windows, are of excellent quality. We noticed an immediate elimination of noise and more importantly drafts from window air leaks. We are confident we will experience a 20% reduction in our heating costs this winter.
The installers were outstanding. They arrived at the appointed time and were informative of what they were doing. They also went to great lengths to make sure we understood how to get the best from our new windows.
I will purchase all of my future window needs from Brock, and encourage all of my friends to do so.
