What Happens When You Don’t Wash Your Windows.

As a business owner, you have a lot on your plate, so the cleanliness of your windows is probably not your top priority. The problem is that dirty windows aren’t just an eyesore; they can lead to more problems down the line. These are only some of the problems you can expect to face if you don’t have your windows washed regularly.


The most glaring issue with leaving your windows dirty is the damage that will happen if left untouched. Here are a few ways that dirt build-up could damage your expensive windows.


Dirt isn’t just soft dust; it is a mixture of all kinds of stuff, including microscopic rocks that can get stuck in the dirt, causing them to rest on the window. When a storm comes along, with may wash your windows, but in the process, it drags those rocks across the glass, causing permanent damage.

Glass Cancer

Dirt can have elements that can break down the glass and cause “glass cancer,” which can discolor, warp, and crack the glass over time.

Broken or Worn Out Seals

Dirt and grime build up and can cause damage to the seals around your windows. Once those seals go, dirt and water can get inside your window or even inside your building and cause more damage.

Increased Energy Bills

If you live in a region like Minnesota, where it is cold at least half the year, you know the pain of paying for ever-increasing heating bills. In the winter, dirty windows block UV light from your windows and prevent those UV rays from giving your building a natural heat boost. So, dirty windows may drive up your energy costs and significantly strain your building’s furnace or boiler.


Dirt will discolor your windows by nature, but if they are cleaned regularly, that discoloration will disappear with every wash. However, if your windows are not washed regularly, that dirt and grime can become ingrained in the pores of the glass, making it impossible to get out and discolor the glass permanently.

Health Risks

It may sound unbelievable but dirty windows may lead to legitimate health risks for your employees.


If your window seals wear out, they will start to let the dirt from the outside in, which can lead to allergic reactions. Even worse, water can get stuck in the window and promote mold growth which is dangerous to breathe whether you have allergies or not.

Lack of Sunlight

Too much dirt on your windows can block sunlight from entering the building, leading to multiple health hazards. The lack of vitamin D can affect your employees’ mental health, and less natural light reduces visibility indoors. Poor natural lighting has also been blamed for employees experiencing headaches, eye strain, and poor concentration.

Poor Curb Appeal

One of the most significant things that will happen if you don’t wash your business’s windows is the negative appearance that your business will reflect. When people see a business with dirty windows, they wonder where else that business is willing to cut corners. Whether consciously or subconsciously, a building with dirty windows will turn off potential customers no matter how successful you are at your business.
