When we did our renovation last fall, this was a big issue for me. One company did the job quickly but left a mess behind. The second time, I looked at this review https://windowtechcanada.ca/best-window-companies-in-toronto/ of the best window installation companies and went with someone known for their professional standards. They laid down window films, moved furniture as needed, and even vacuumed the area after installation. Their attention to detail was impressive – not just during the work, but in the way they treated the house. Even our pets were not stressed. The manager double checked everything before leaving and came back a week later to make sure there were no issues. The little things made all the difference and showed that they care about more than just getting a paycheck. It’s worth going with someone on this list.
