White Shark advertises itself as a window cleaning company when in fact it is only a glass cleaning company. A window is more than just the glass pane. When you buy a window, you don't just get handed the glass. A window is made up of other components and when you ask for window cleaning, it goes without saying that you would like the entire window cleaned - sill, frame, all of it. White Shark doesn't do this. They also just show up after you request a job without settling on an appointment date and time with you. When I pointed this out to the first crew that showed up out of the blue, they told me that the owner doesn't even have to be home when they come. Well the owner should be home because they don't do a good job. As already mentioned, they only cleaned the glass and even that was done with only a squeagy that kept being dipped in the same dirty water over and over again. I won't be calling them again or referring my friends and neighbours.
