When the cold weather sets in, it’s essential to ensure that your double glazing windows are properly maintained. Double glazed windows are designed to provide insulation, helping to keep your home warm and energy-efficient during the winter months. However, to keep them performing at their best, regular maintenance is necessary. 

Why Double Glazing is Important in Winter

Double glazed windows are made of two panes of glass with a gap between them, typically filled with air or gas. This structure helps insulate your home, reducing heat loss and keeping your rooms warmer. Additionally, double glazing can reduce noise and prevent condensation from building up inside your home. However, like all components of a house, double glazed windows require maintenance to ensure they continue to perform effectively.

Common Problems with Double Glazing in Winter

While double glazing offers many benefits, there are a few common problems that can arise, especially in the winter. Understanding these issues and knowing how to address them can save you time and money in the long run.

1. Condensation Between the Panes

One of the most common problems with double glazing is condensation between the panes of glass. This occurs when the seal on the window unit breaks down, allowing moisture to get trapped between the two panes. The result is a foggy appearance that can affect both the aesthetics and the performance of your window.

To prevent condensation, ensure that your double glazed units are properly sealed. If condensation does occur, the window will need to be repaired or replaced, as the seal cannot be fixed by simple cleaning. Regularly check for signs of condensation, especially during colder months when the difference between indoor and outdoor temperatures is most significant.

2. Drafts and Cold Spots Around the Frame

Double glazed windows are designed to provide excellent insulation, but drafts can sometimes occur around the window frame. This is often due to wear and tear on the seals or damage to the window frame itself. When this happens, it can lead to cold spots in your home and higher energy bills as your heating system works harder to maintain a comfortable temperature.

Inspect the window frames regularly to check for cracks or gaps in the seals. If you find any, these should be addressed immediately. Replacing the seals or applying a small amount of weatherproof sealant can help to restore the window’s energy efficiency.

3. Malfunctioning Moving Parts and Locks

The moving parts of your double glazing windows, such as the handles, hinges, and multi-point locks, can wear down over time. If these components are not properly maintained, they can become stiff, making it difficult to open and close the windows. In some cases, the lock may even fail to function, compromising the security of your home.

To prevent issues with moving parts, ensure that you clean and lubricate the locks and hinges regularly. Use a light machine oil to lubricate the moving components, and avoid using harsh chemicals that may damage the window. Regularly check that the multi-point locks engage properly and that the window opens and closes smoothly.

Steps to Maintain Double Glazed Windows in Winter

To ensure your double glazing windows are ready for the colder months, follow these simple steps:

1. Clean the Windows Regularly

Cleaning your double glazing windows is one of the easiest ways to maintain their condition. Use warm soapy water and a soft cloth to wipe down the window panes and frames. Be careful not to use abrasive materials that can scratch the glass or frame. Regular cleaning prevents dirt and grime from building up, which can interfere with the window’s insulation properties.

Pay special attention to the window frame, as dirt and debris can get trapped in the seals, causing them to degrade over time. Clean the frames and surrounding areas regularly to prevent this from happening.

2. Inspect and Clean the Trickle Vents

Trickle vents are small openings in the window that allow for ventilation. These vents help to prevent condensation from building up inside your home by allowing air to circulate. In winter, it’s particularly important to ensure that these vents are clear of debris and functioning properly. Check the vents regularly to make sure they are not blocked by dirt, leaves, or other debris.

If the vents become clogged, the lack of airflow can lead to condensation inside your windows, which can cause damage over time. Clean the vents with a small brush or cloth to ensure proper airflow.

3. Lubricate the Moving Parts

As mentioned earlier, the moving parts of your double glazing windows require regular lubrication. Use a small amount of light machine oil on the hinges, handles, and multi-point locks. This will help prevent the parts from seizing up and ensure smooth operation of the windows. If the locks are stiff or difficult to turn, apply a little lubricant to the locking mechanism and work it in by turning the key a few times.

Be cautious not to over-lubricate, as excess oil can attract dirt and cause the moving parts to become sluggish.

4. Check for Drafts and Seal Damage

Over time, the seals around your double glazed windows can become worn or damaged. This can lead to drafts, which reduce the effectiveness of your windows and allow cold air to enter your home. To prevent this, inspect the seals around the window and door frames regularly. If you notice any damage or gaps, replace the seals to maintain the window’s insulating properties.

If you live in an area with particularly harsh winters, it may be a good idea to invest in higher-quality seals that can withstand the cold temperatures.

5. Monitor for Foggy Windows

As mentioned earlier, condensation between the panes of glass is a common issue in winter. If you notice foggy windows, this is a sign that the seal on your double glazed unit has failed. Unfortunately, there’s no simple fix for this problem. You’ll need to have the window repaired or replaced to restore its insulating properties. In some cases, the window may still be under warranty, so it’s worth checking with your supplier.

6. Ensure the Window Frames Are In Good Condition

The frames of your double glazing windows play a crucial role in their overall performance. Ensure that the frames are in good condition by checking for cracks, chips, or signs of deterioration. Wooden frames, in particular, can be susceptible to damage from moisture, so it’s important to treat them with the appropriate sealant or preservative. UPVC windows are more resistant to weathering, but still require maintenance to ensure that they stay in good condition.

If you notice any damage to the frames, address it promptly. Repairing minor cracks or chips early can prevent further damage and help maintain the window’s performance.

When to Call for Double Glazed Window Repairs

While regular maintenance can go a long way in keeping your windows in good condition, some problems require professional attention. If you experience any of the following, it’s best to call a professional for double glazing repairs:

• Condensation between the panes of glass: This is a clear indication that the window seal has failed and will need to be repaired or replaced.
• Malfunctioning locks or handles: If the window’s locks or handles are not functioning properly, a professional can diagnose the issue and make any necessary repairs.
• Damaged frames or seals: If the window frames or seals are beyond repair, a professional can help replace them and restore the window’s insulation.

Maintaining your double glazing windows in the winter is essential for ensuring they continue to perform at their best. Regular cleaning, lubrication, and inspections can prevent common issues such as condensation, drafts, and malfunctioning moving parts. By taking the time to care for your windows, you can keep your home warm, energy-efficient, and secure throughout the colder months. If problems arise, don’t hesitate to call a professional for double glazing repairs to ensure your windows are functioning properly.
