Double Glazing Problems and How To Solve Them

Even the highest quality double glazing can encounter problems. It's never ideal, but it's always best to resolve them early, before they become even bigger problems. As professional glaziers in Devon, who specialise in glazing repairs, we've put together a guide detailing common double glazing problems and effective solutions for them.

Mould From Condensation

Problem

Condensation issues with windows are often attributed to property conditions rather than faults in the windows themselves, unless condensation occurs between the panes of glass. If you notice frequent condensation forming on the interior of your windows, it can lead to the accumulation of mould around the window seals. This build-up can compromise the integrity of the seals over time, potentially causing further issues. Factors such as drying clothes indoors or having furniture placed too close to walls can worsen condensation problems by trapping moisture in the air.

Solution

To alleviate condensation-related issues, it's crucial to address them promptly. When you observe condensation on your windows, especially on a regular basis, it's essential to wipe it away as quickly as possible using a dry cloth. This helps prevent moisture from lingering and contributing to mould growth. Additionally, improving ventilation in moisture-prone areas of your home, such as bathrooms and kitchens, can significantly reduce condensation build-up. Opening windows during activities like cooking or showering allows moist air to escape, preventing it from settling on window surfaces. By implementing these measures, you can effectively manage condensation and minimise the risk of mould formation around your windows.

Broken Seals

Problem

One of the most challenging issues with double glazing occurs when the seals between the panes break, leading to condensation forming inside the glass. This problem can arise due to various factors, including the formation of mould within the windows or simply the deterioration of the seals over time. When seals fail, it compromises the integrity of the double glazing unit, impacting its effectiveness in insulation and aesthetics. Draughts and leaks in double glazing often stem from seal issues. A broken seal can allow cold air to enter through the window, while improper sealing between the frame and wall can exacerbate draughts. Leaks, similarly, are commonly caused by damaged weather seals or blocked drainage systems within the window.

Solution

Fortunately, when seals break in double glazing, you don't always need to replace the entire window. Instead, replacing the seals can restore the gas gap between the glass panes, resolving the issue. Repairing broken seals by replacing them can effectively eliminate draughts and leaks in double glazing. Additionally, ensuring proper sealing between the frame and wall can further reduce draught issues. For leaks, contacting a glazing repairs specialist to address broken weather seals is recommended. Alternatively, clearing blockages in the drainage system can resolve leaking problems, offering a cost-effective solution. While broken seals may not significantly affect your home initially, it's essential to address them to maintain the efficiency and appearance of your windows. Some home/business owners opt to wait until all windows require replacement before addressing seal issues, but prompt replacement by professional glaziers in Devon, can help avoid further complications and ensure optimal performance of your double glazing units.

Trouble Opening, Closing or Locking Windows

Problem

Difficulty in operating windows, such as struggling to move handles or close them, often occurs due to debris accumulating in the hinges. This debris can hinder the smooth functioning of the window mechanism, potentially compromising its operation and security. Additionally, loose handles or hinges can contribute to difficulty in closing or locking windows, leading to further operational issues.

Solution

Regularly inspecting and cleaning the hinges and locking mechanism can help prevent the accumulation of dirt, ensuring smooth window operation. Use a vacuum attachment or a thin tool to remove any debris lodged in the hinges. Tightening loose handles and hinges with a screwdriver may resolve operational issues; however, if the problem persists, consider replacing the faulty components. In cases where windows feel stiff to open, applying a small amount of oil to the mechanism can help lubricate and loosen it. Additionally, be mindful of temperature changes, as extreme conditions can affect the window frame's size and operation. Wiping down the frame with cold water in hot weather or waiting for temperature adjustments may help those with operational difficulties.

Discoloured Frames

Problem

White UPVC windows can discolour over time due to inadequate cleaning or exposure to the sun's UV rays. This discolouration can detract from the appearance of the windows, affecting their aesthetic appeal. Despite efforts to clean the frames with specific cleaning products, discolouration may persist, indicating aging frames that require replacement.

Solution

To restore UPVC windows to their original colour, consider using specialised cleaning products designed for this purpose. However, if discoloration persists even after cleaning attempts, it may signal that the frames are reaching the end of their lifespan and need replacement. Generally, high-quality double-glazed windows maintain their condition for 20-30 years without significant issues, but as they near the end of their lifespan, discoloration and other problems may become more prominent. Regular maintenance and timely replacement can help ensure the longevity and aesthetic appeal of your windows.

In conclusion, maintaining your windows is key to preserving their functionality and appearance. From handling condensation to addressing discolouration, proactive maintenance can extend their lifespan.
