“We rebuilt our cottage, and in the planning stages with our builder, Bill Ferguson, choose to work with Muskoka Window and Door Centre. They know Muskoka topography and the nuances involved. We’re thrilled with the results. We love our windows and doors, the quality is exactly what we were after, knowing these windows would last and handle the Muskoka climate changes. We REALLY appreciated the installation team, and all the service that we have received since we moved back in. MW&DC looked after the small details, which for us, made a big difference.”
