We were looking for a reliable and responsible company to change the doors and windows of our house. After three submissions, we did not hesitate to use Portes et Fenêtres L’Assomption’s services. Not only did Stéphane present us with a competitive price, but his transparency and his genuine know-how convinced us. His team of professionals and the quality of the products used met our requirements. The gave us a good guaranty on the work they did, a fast and efficient service, even after the installation.
We were looking for a company we could trust and found it with Portes et Fenêtres L’Assomption.
