Exceeded Our Expectation

“A pleasure working with a family run business with years of experience and expertise. In summary, Deb's expert advice on the front end, and Arthur's attention to detail on the back end (installation) exceeded our expectation. It was a refreshing change to work with a service provider focused on delivering service excellence. That's how you stay in business for 50 years and counting.”

Helpful and Knowledgeable

“Very happy with my new windows from TrueSeal. Everyone was pleasant to deal with. They took their time to answer all my questions and were always helpful and knowledgeable. The installers were great and took their time to make sure everything was perfect. Highly recommend this company. Thank you Deb Cook and staff!”

Windows Are Good Quality and Very Attractive

“I replaced all the windows in our home with TrueSeal. The windows are good quality and very attractive. Thank you Deb for helping me at the very beginning when I did not know where to start. Thank you Ian for answering all my questions so patiently and spending so much time with me going over everything! A big thank you to Stace who installed all the windows and did an excellent job. He was very pleasant to work with and made the installation run very smoothly and easily!”

End Result Was Beautiful

“I replaced all the windows in my house and TrueSeal (Brampton) was amazing from start to finish. Everyone was knowledgeable, helpful and very professional. Ian worked very hard during the installation and the end result was beautiful. The windows are high quality and I know from family who have also used TrueSeal windows that they wear the test of time. I am extremely satisfied with the service and product I received from TrueSeal and would recommend them without hesitation.”
