(May 26, 2021, 8:35 pm)This was my second time ordering windows and doors from Ostaco. I visited the showroom to visualize some of the door options late March, and placed my order the same day. Considering the supply chain challenges related to Covid, I have to congratulate the Ostaco team for delivering on time. As for the product quality, it didn't disappoint either. The Prism windows are beautiful, modern and gave a much cleaner look to my old Toronto house. Keep up the good work!
