Surprising Health Risks of Dirty Windows

Dirty windows in an officeWindows are a great addition to the office, if only because they offer a visual break from the harsh lighting and constant computer screens. At the same time, however, they may present an unexpected health risk – especially as many of us don’t realize they can be dangerous in the first place. Surely, after all, a dirty window isn’t that risky, right? Actually, dirty windows are surprisingly unhealthy if poorly maintained.

Bacteria on Dirty Windows

A glass window may look clean, but unless it’s sanitized regularly, it could be a hot spot of bacterial colonies. Since window maintenance isn’t usually a daily affair, they offer a safe space for microbes to grow without restriction. This can lead to airborne diseases and pathogens spreading around the office strictly from dirty windows.


Unless you clean your office windows regularly, they can accumulate plenty of dust – and worse – dust mites. Dust mites are small insects that love dirty windows and can cause respiratory issues and allergic reactions because of their feces, which may create airborne health hazards.

Air Pollution

Research suggests that old, urban windows in commercial and residential buildings may contribute to airborne pollutants. If a coating of grime covers your dirty windows, this will be particularly pronounced. Grime can introduce certain nitrogen compounds which are linked to smog – the last thing you want is for this to enter your office air!


Windows are not the best insulation in a building, particularly in older buildings or if the dirty windows are poorly maintained. This can cause condensation, and whenever you have damp, humid air and water, you get mold. If you have a mold problem and condensation around your windows, consider replacing them with better frames – and above all else, regularly cleaning your window sills and frames.
