Revitalize Windows & Doors
Home Window Replacement Companies in Oshawa
Average rating: 5 out of 5 starsMarch 22, 2024
“I came across Revitalize Windows & Doors searching online for a window repair specialist to change a few defective window cranks at my home. I was impressed by their reviews. Getting a quote was very easy, they provided one within a few minutes. I scheduled a service date right after and they replaced my 4 defective window cranks. While the service guy was here he also was able to repair my sticking sliding patio door which I’ve been meaning to fix. Great service and happy with the outcome. Will use again for any window or door repairs.”
