Windows are essential parts of our home. They naturally provide ventilation, fresh air and source and natural lighting. Windows also come in different designs and shapes, pretty much standard is the square one and they also have different functions. Good thing is that they are low maintenance. But when was the last time you checked your windows? The condition perhaps and the problems they might have caused. Some home owners take 20 years to notice and check the problems. Some homeowners also think their windows are made to last forever, but that's a mistake some of us believe.
