Fantastic, Professional and Courteous Alex and Crew arrived on time and ready to work! They explained everything they were going to do and made sure we understood. I was getting 10 windows installed in my Etobicoke row home. The crew also was extremely professional. They introduced themselves with a nice smile and a handshake. Also, they needed to use my restroom , but asked kindly before they did. I couldn't be happier! The quality of workmanship is phenomenal!! I would definitely recommend Installer Windows & Doors for their top notch quality work, courtesy and professionalism.
