What a positive experience during recent renovation project. The sales and installation were done in a timely, accurate, attentive way. I was impressed with the personalized attention I received from an evening call from telemarketers; the sales rep, Dan, that provided the quote; the scheduling and booking department; and the installation crew that did the field work flawlessly. Would highly recommend for windows replacement and plan to use Loyal Seal again for patio door and front door replacement next year. Thank you so much guys.

With the windows company that replaced all the windows and doors in our house, but had gone out of business a couple of years ago, we were left with the glass that had a broken seal and thus looked foggy and pink throughout the surface as if being utterly dirty (especially an unattractive look as the windows represent the house from the front of the house). The two doors, leading to the garage and to the outdoors from the mudroom, original to the house, needed a replacement as well. Loyal Seal provided a well-supported on every level service from the inquiry call, to the estimate and measurements, reminders and the actual installation: a polite and courteous demeanour of all the employees, competent appraisal, followed by expert and clean work made a great impression. We have been through numerous renovations over the past 20 years, and had anywhere from mediocre to very bad experiences with the services. Loyal Seal had made the process very enjoyable and exciting. Tatiana and Michael.

They offered me a free estimate on my windows with a guaranteed quote for 2 years, and they even tell me to shop around with the quote because they want me to get the best price.
There is no pushy sales and the best thing is that you’re not dealing with contractors directly as they have a separate department for customer service which shows you how much they truly care about their customers!
Also, all their products are manufactured here in Canada!
If you have any problems with your windows and doors, you should give them a call!

Great quality windows and doors. Service was super friendly and it was done in a quick manner. Would definitely recommend if you’re looking to get any upgrades!
