We are so happy with our new doors and windows installed by St Clair. Their team of professionals was easy to work with offering valuable direction and communication throughout. Their team working in our home were polite, efficient and communicated throughout the installation. I highly recommend St Clair Windows and Doors!

From start to finish these guys were great to deal with. Once we met Jonathan we knew these were the people we wanted to go with. The guys showed up every morning on time and got to work. They cleaned up every evening. They had one guy who chatted with me everyday to let me know what was happening. I didn't get his name but he was a very friendly chap and a great communicator. They did a fantastic job and our house looks amazing. It looks like a whole new house. We love it! Any minor issues we ran into were dealt with promptly and professionally. We highly recommend!
