What Causes Foggy Windows?

Foggy windows occur due to a difference in temperature and moisture levels inside and outside the vehicle or building, leading to condensation. Foggy windows are a result of moisture or condensation forming between the panes of a window. The primary cause of foggy windows is a compromised or failed seal that allows moisture to enter the space between the glass panes, although there are other factors that may cause your residential windows to fog up.

Failed Seal

The most common cause of foggy windows is a broken window seal. Double or triple-pane windows have sealed spaces between the glass panes that are filled with insulating gas, such as argon or krypton. While this gas helps improve the window’s energy efficiency, when the seal breaks, moisture-laden air can squeeze between the panes. When this happens, our experienced team can advise you on whether or not repairing the window seal is the solution to your foggy window problem.

Temperature Changes

Temperature fluctuations can exacerbate the issue of a foggy window. As you probably know from observation, when the outside temperature is colder than the interior of your car or building, you’ll get foggy windows. This is especially noticeable during the colder months.


High levels of indoor humidity can contribute to condensation on the inner surfaces of windows. This moisture can find its way into the space between the glass panes if the seal is broken or faulty.

Aging Windows

Over time, windows age, and seals wear out. UV rays, exposure to the elements, and temperature changes all contribute to the breakdown of the seal’s effectiveness, resulting in the need for a foggy window repair. 

Manufacturing Defects

In some cases, windows may have manufacturing defects that affect the integrity of the seal from the start. These defects can lead to premature seal failure and foggy windows.

Poor Installation

Improper installation can also contribute to seal failure. If the windows of your home aren’t installed correctly or if the seal wasn’t properly applied, it can lead to gaps that allow moisture to enter. This ultimately leads to foggy windows.

When to Request Foggy Window Repair

If your windows are constantly fogging up, it can indicate that your home is losing valuable energy through windows that aren’t properly sealed. Not getting your home’s foggy windows repaired can lead to further issues such as mold growth, water damage, and high energy bills. 

If any of the following issues are present, request foggy window repair services.

Visible Condensation

If you notice visible condensation or fog between the glass panes of your windows, this is a clear indication that the window’s seal has been compromised. This moisture can obstruct your view and indicate reduced insulation efficiency.

Persistent Fog

Fog that doesn’t dissipate, even when the weather conditions change, suggests that the moisture has become trapped between the panes. This is a sign that the window’s seal is no longer effectively preventing moisture infiltration.

Mold or Mildew Growth

Moisture trapped between the glass panes can create an environment conducive to mold and mildew growth. If you see signs of mold or mildew on the edges of the glass or in the space between the panes, it’s crucial to address the issue promptly for your health.

Reduced Insulation

Foggy windows compromise the insulating properties of your windows. If you notice drafts, cold spots, or an increase in energy bills, it’s likely that your foggy windows are no longer providing the insulation they should.

Older Windows

If your windows are older or you haven’t had them inspected in a while, it’s a good idea to have them checked by a foggy window repair contractor. Over time, seals can deteriorate, leading to foggy windows.

Cracked or Damaged Seals

If you notice cracks or damage to the seals around your windows, it’s likely that moisture can easily enter the space between the glass panes. Addressing this issue early can prevent further damage.

Impaired Functionality

Foggy windows can compromise the functionality of your windows, making them difficult to open, close, or lock. If you experience any issues with window operation, it’s a sign that the window’s seal may have failed and your home is due for a foggy window repair service.

Foggy Window FAQs

What causes foggy windows?

Foggy windows occur when condensation forms when the air is warmer and more humid that the glass window. As the warm air begins to cool, the moisture condenses and you’ll notice fog on your windows.

Foggy car windows are a result of 3 factors.

  1. Temperature Difference: When the air inside the car is warmer than the air outside, and there’s enough moisture inside, the moisture condenses on the cooler surface of the windows, causing them to fog up. This is most common in colder months.
  2. Humidity: High humidity levels inside the car, such as passengers breathing or wet clothes, increase the likelihood of condensation.
  3. Air Circulation: Limited air circulation can exacerbate the issue, as the moist air inside the car is not replaced by drier air from outside.

Use the defroster setting on your vehicle’s climate control system to dissipate fog. This setting directs dry air to the inside of the windshield and side windows to evaporate the condensation.

Foggy windows in your home are a result of 3 common factors:

  1. Temperature Discrepancies: Similar to cars, a significant temperature difference between the inside and outside of a building can cause windows to fog up. This is particularly common in winter, when the indoor air is much warmer than the outdoor air.
  2. High Indoor Humidity: Cooking, showering, and using humidifiers can increase indoor humidity levels, leading to foggy windows.
  3. Inefficient Windows: Older or poorly insulated windows can exacerbate fogging because they allow a greater temperature difference between the interior and exterior surfaces of the glass.

Improving ventilation, using dehumidifiers, and ensuring windows are well-insulated can help reduce indoor humidity and prevent foggy windows. If you’ve tried these solutions but still have a problem, have your windows inspected or request foggy window repair.

Foggy windows should be fixed, but that doesn’t necessarily mean you have to pay for replacement windows – it may be as simple as fixing the window seal. To get an opinion from one of our Raleigh glass professionals, request a free estimate for your foggy window repair today.

Your windows expand and contract as the temperature fluctuates. On hot days when the sun is heating up your window, it causes the entire window unit to expand. As the weather cools down in the evening, your entire window unit will contract. This expansion and contraction puts pressure on your window’s seals, pushing air out through the seals.

Over the course of time, the stress on your window’s seals causes more air to get in, and along with the air comes moisture – which results in the foggy appearance. When a window seal cracks, becomes damaged, or simply wears out over time, it will not protect the inside of your home from the outdoor temperature.

Often times, a foggy double pane window can be repaired by simply replacing the window seal. To request a free quote from the professionals at Glass Solutions in Raleigh, fill out the form below.
