Ariy from Mississauga

I have been using gold standard for a few years now, they came out and cleaning my windows, my neighbors, and my aunts house down the street. The crew was very professional and took the time to do a quality job. It has been three weeks since the cleaning and the windows still sparkle. I got just the outsides cleaned which was a bit of a mistake since you could then clearly see how dirty the insides were, I then had to clean the insides myself. Next time I'll just do both at once.
