What Causes Misted Double Glazed Windows?

Double glazing is a popular choice for homeowners due to its energy efficiency and sound insulation properties. However, over time, double glazing units can develop problems, such as blown seals or condensation between the panes of glass.

Double glazed windows are made up of two glass panes separated by a spacer bar, which is filled with a gas or air. The seal between the panes can become damaged over time, allowing moisture to enter the space between the panes. This moisture can condense on the inside of the glass, causing the window to become misted.

Why Do Double Glazed Windows Become Misted?

Misted double glazed windows are caused by a buildup of moisture between the two panes of glass. This makes it difficult to see through and gives the window a cloudy appearance. 

Not only does this detract from the aesthetics of your home, but it can also indicate a problem with your windows that could lead to more serious issues down the line. 

This can happen due to a variety of reasons, including:

  1. Poor Installation: If your double glazed windows were not installed properly, gaps can form between the panes of glass, allowing moisture to seep in.
  2. Broken Seals: Double glazed windows are designed with seals around the edges to keep moisture out. If these seals are broken, moisture can get in and cause fogging.
  3. Age: Over time, the seals around your double glazed windows can deteriorate, allowing moisture to enter and cause fogging.

The Risks of Misted and Blown Windows

Misted double glazing windows can lead to several problems if left unresolved. Here are some of the key risks and drawbacks associated with foggy windows:

  • Reduced Visibility: The foggy appearance of misted windows limits the amount of natural light that enters your space, making it difficult to enjoy the view outside or see clearly within your home.
  • Energy Inefficiency: When condensation builds up between the glass panes, it compromises the insulating properties of the window. As a result, your home’s energy efficiency may decline, leading to increased heating or cooling costs.
  • Damaged Aesthetics: Misted windows can detract from the overall appearance of your property, making it look neglected or poorly maintained. This can be particularly problematic if you’re planning to sell your home or enhance its curb appeal.
  • Risk of Mould Growth: Excessive moisture trapped within the window can create an ideal breeding ground for mould and mildew. This not only affects the window itself but also poses potential health risks to the occupants of the property.

Can Misted Double Glazed Windows Be Repaired?

In most cases, misted double glazed windows can be repaired without the need for a complete window replacement. The most common method of repairing misted windows is by replacing the glass unit while leaving the existing frame in place.

If your windows are misted, we do recommend hiring a professional to fix double glazing condensation or replace the window. This way there’s a reduced risk of personal injury and damaging your home or windows.

Resolving Misted Double Glazing Windows

Clearing misted double glazed windows involves removing the moisture trapped between the panes. This can be done by either repairing or replacing the glass unit. The method you choose will depend on the severity of the problem and your budget.

Fortunately, there are effective ways to resolve the issue of misted double glazing windows and help to stop condensation on windows. Here are some recommended methods:

1. Professional Window Repair

One of the most reliable and long-lasting solutions is to seek professional assistance for window repair. Trained technicians can assess the extent of the damage and employ industry-standard techniques to fix the issue. They will likely follow these steps:

  • Remove the affected window unit from its frame.
  • Disassemble the unit, separating the individual glass panes.
  • Clean and dry each pane thoroughly to eliminate any moisture or debris.
  • Replace the damaged sealing materials.
  • Reassemble the window unit and reinstall it securely.

2. Window Replacement

In cases where the misting issue is severe or the window itself is structurally compromised, window replacement may be the most suitable option. Replacing the entire window unit with a new, energy-efficient one can provide long-term benefits, including enhanced aesthetics and improved insulation.

3. DIY Solutions

While professional repair or replacement double glazed units is recommended for optimal results, there are temporary DIY methods you can try as a stopgap measure. These include:

  • Silica Gel Packets: Placing silica gel packets inside the window frame can help absorb excess moisture and reduce misting temporarily.
  • Dehumidifiers: Using a dehumidifier in the affected area can minimize condensation and improve the clarity of your windows.
  • Ventilation: Ensuring proper airflow by opening windows or using extractor fans can help mitigate moisture buildup.

Preventing Misted Double Glazed Windows

Prevention is always the best approach when it comes to misted double glazed windows. Here are some tips to help you prevent fogging in the future:

  1. Use Ventilation: Proper ventilation is key to preventing moisture buildup in your home. Use extractor fans in bathrooms and kitchens, and open windows regularly to allow fresh air to circulate.
  2. Check Seals: Regularly inspect the seals around your double glazed windows and have them repaired or replaced if they are damaged.
  3. Repair Leaks: Any leaks in your home, such as a leaky roof or plumbing, can contribute to moisture buildup and fogging.
  4. Invest in Quality Windows: Investing in quality double glazed windows from a reputable supplier can help prevent misting and other issues down the line.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
