A home’s windows can become dirty due to a variety of causes such as trees, pollen, pests, weather, and more. It’s recommended that residential windows are cleaned at least one to two times per year (usually in the spring and fall) to maintain a clear view and protect them from premature aging or damage. When dirt and grime are left to build up on the glass of a window, it can result in scratches. Dirt and debris can collect in the track of a window which can make operation more difficult. If you are in an area with many trees and pollen or high winds, your windows may benefit from regular cleaning 2-3 times a year. Not only will window cleaning bring a fresh vibrance to a home’s exterior, but it will also help elongate the lifespan of windows drastically.
