They were great. We had all our windows replaced. I was not sure about privacy windows in the bath rooms that Leo mentioned but it was a great idea and no regrets. They had replaced our door a few years ago and before Alex left this job he adjusted our door because it was not quite right. Alex and Leo were great. Highly recommend this company.

Renaud and his team replaced all my upstairs windows and fixed my patio door last month - the installation crew arrived on time and did an excellent job installing the windows - very professional. All my questions were answered, and overall I'm very pleased with the final product! Windows look great!
