Our standard service includes: * Cleaning the glass (interior and exterior) * Brushing the insect screen * Wiping out the tracks on the interior frame. We use a specialized cleaner designed just for glass. It is 100% biodegradable and environmentally safe, so you don't have to worry about harmful effects on your family, pets or landscaping plants. We apply the cleaner with specialized tools and squeegee each window to completely remove the cleaner. After we have cleaned your windows you will have streak-free, shiny, clear glass that is actually protected from deterioration and weathering to stay clean longer.
