Alex did an amazing job our windows they look terrific crystal clear. I don't know what his secret is for cleaning the screens but they are beautiful, just like new! I highly recommend Ziggy's Cleaning Service if you want the cleanest windows and screens possible. Ziggy's also does pressure washing both high and low pressure, mirrors and glass shower doors as well as hard water stain removal. I have not used all their services yet but would not hesitate based on the performance, affordability, and excellent service we received from them cleaning our windows.
