Replace All 14 Windows In House

Windows & Doors Installation & Service in St. Catharines

Based on an ad I received, I called this company and had the wonderful pleasure of meeting Igor. He proved to be polite, courteous, professional and honest. Igor was patient and took the time to answer any & all questions we had at any step in the process. He willingly met with & co-ordinated with other workers we had at the house doing siding. Igor's work team, Antin & Val, were amazing also. They were extremely professional, polite, courteous and efficient. All work was amazingly completed in one day, including building a new bay window in our driveway and installing it in the front room! At the end of the day, they made sure everything was cleaned up spotlessly. I would never hesitate to have any of these gentlemen do work for me again, and would certainly very highly recommend them to anyone looking to have their windows done. Canadian Choice Windows has been an awesome company to deal with in every way, from start to finish!
