Because it feels good to have clean windows!
Getting your windows cleaned on a regular basis is also an important part of protecting the glass at your home or business. If you neglect your windows for extended periods of time, environmental pollutants will build up on them! If these contaminants are left there, they will chemically bond with the glass, like rust etching steel. Regular window cleanings will prevent this damage and maintain your investment.
Plus, here in Calgary and all of Alberta, we need all the sun we can get! Let the sunshine in through clean windows and feel at peace.
