How I got involved with window cleaning
In 1985 I was working at a gas station; the owner of a local residential window cleaning company would frequent the gas station to fill up with gas. One day, by chance, I cleaned the owner’s car window and was offered a job. I worked with them for a while, cleaning residential home windows but soon longed for the challenge of commercial projects. I was lucky enough to land a commercial cleaning job that helped me gain the experience necessary to offer a safer, more affordable and friendlier service to my own clients. In 1989 I started AJ Window Cleaning Services and have loved it every since. My dream job would be to clean the windows at Skylon Towers in Niagara Falls, Canada. The Skylon Tower is located in the heart of the Niagara Falls hotel, dining and entertainment district and  is the most famous landmark next to the Falls. Official website...
