My two houses are built by Minto. I have my 5 large windows changed by the manufactory after the house closed more then 4 years. You should call the window manufactory, you have this information when the house was closing. If you miss this, call Minto, they will provide this information. Minto is a reliable builder. They will do any thing on the contract. Once the house is closed, any issues that is not reported should be turned to warranty.
