Our house is over 60 years old and we still had the original windows. We began work just over 2 years ago in 2016 and had the front picture windows replaced (retrofit) and were extremely happy with the work. We tried to replicate the proportions and function of the original windows in this bungalow from the 1950s as closely as possible. The windows from 2016 have been great in summer and winter. So much so that we finished off all the rest of the windows this summer (with a brick to brick installation) 2018, when I heard about the Ontario Rebate for window replacement. I was even happier in 2018 with the work of the three-man team from Ambia. The salesman Brian was informative and patient despite the difficulties of providing the Vinylbilt windows this year; Tony was flexible and extremely helpful about the date of installation (in spite of the chaos caused by the cancellation of the rebate programme suddenly in June) since we had a narrow window of opportunity in August for the installation, and the team did absolutely meticulous work inside and outside. And I am really fussy. Fantastic. I can't thank you all enough for your efforts on our house.
