How to Repair Double Glazing Windows

You may experience problems with the handles of your double glazing, hinges, and gaskets. It is often possible to fix these problems without having to replace the entire window, which saves money and time.

One of the most common issues is the accumulation of condensation in the space between the two panes of glass. This usually indicates that the window is faulty and requires attention.

1. Broken Panes

A damaged double pane window doctor is a major issue and can expose your home to the elements. However, it's not always necessary to replace the entire window sash in order to resolve this problem. Double pane windows can be fixed with an adhesive specifically designed for the cracks.

This short-term fix is usually used to prevent superficial cracks (such as stress cracks) from getting worse, which can occur when temperature changes cause the glass to expand and contract. If your glass is damaged you may have to take it off and replace the entire window.

Sometimes, the seals between two glass panes can be damaged or worn out, causing condensation and misting of windows. These problems are usually caused by moisture trapped between the glass panes or is absorbed into the wall through the window frame. Regardless of the source moisture is a problem for windows with double glazing because it can lead to water damage and mold growth and can be expensive to treat.

You can try to resolve the issue by wiping your double-glazed windows using cold, lukewarm water. This can help to temporarily solve the issue, especially if the weather is warm and humid.

A tool can be used to draw an outline of a score line around the perimeter of the windows, which allows you to cut the glass using a glass cutter. Once you have finished and you are done, you need to remove all glazing points and putty from the frame of your window opening. This is best done while the sash is still in place, however it's easier to work on a flat surface such as a table.

2. Seals

The window seal is an essential component of double glazing. It plays a crucial role in keeping your home efficient, draught-free, and safe. The seal covers the entire frame's uPVC frame and provides an air-tight seal over the gas-filled space between the two panes of glass that make up the window. The seals are a vital component of double glazing's insulation. If they fail or are faulty, this will be reduced.

If your seals don't do their job, you will see condensation between the panes. This isn't just unsightly; it can lead to damp and mould in the home. It can damage floors, furniture, walls and cause serious health problems for those with respiratory conditions such as asthma.

The majority of double-glazing manufacturers provide a service that allows you to repair your windows without the need to replace the entire unit. This is not only cheaper, but also quicker and more environmentally-friendly. In the meantime, there are DIY alternatives, such as using caulking to tackle moisture and leaks or lengths of self-adhesive seals which can be applied directly to the window frame's junction frame and double glazing sash.

In most instances, the easiest and most effective way to tackle failed window seals is to contact a professional. They'll be able to replace the window seal, preventing the infiltration of air and moisture, which can cause expensive damage and also aid in keeping your home energy efficient.

It is worth looking over the documentation of your double glazing to determine if it has a warranty period - 10 to 20 years is the norm and can save you money if the windows have to be replaced because of broken seals. Some installers drill holes into the misted double glazing in order to remove the moisture and create an entirely new seal. This will prevent it from misting in the future. This is a temporary fix and a plug must be inserted to seal the hole.

3. Locking Mechanisms

Double-glazed windows have gaps of air between glass panes in order to keep out the elements and also to keep heat in the house. This type of window is also referred to as an IGU or insulated glass unit (IGU). They can give you a lot of energy efficiency that can save on your heating expenses. However, they are not impervious to damage and some issues may occur that require double-glazing repairs.

Many of these issues are fixable and are less expensive than replacing the entire window. It is recommended to contact a specialist firm that provides repair services for double glazing, so that you can be sure that the work is completed efficiently and with minimum effort. These companies will often provide an estimate free of charge to allow you to compare the prices and quality of their work.

It is crucial to confirm the warranty included with your double-glazed window as it will typically pay for repairs. This is a common feature of double-glazing installations and typically lasts for 10 to 20 years, though certain companies offer lifetime warranties.

If you cannot open your double glazed window or it appears that there is a mist between the panes, it is likely because the seal has failed. This could happen when the frame of the window moves in a slight manner, or when the packaging that holds the glass sheets in place wears out with time.

There are ways that you can repair windows with double glazing yourself, however it is usually much more efficient to work with a professional company. If you decide to attempt it yourself then you should always follow the instructions of the manufacturer and use specific tools for the job. You also risk voiding any warranty if you attempt to remove the window glass by yourself. You may end up paying more than if the company that purchased the windows from contacted you.

Once the broken pane is removed, you can put it back with plastic spacers to make sure it fits in the frame and add any necessary uPVC beading. After that, you can install a new wedge gasket and secure the window in the frame.

4. Weatherproofing

If your double glazing windows are difficult to open or are sagging there are methods of fixing them. For example, you can try oiling the mechanisms, hinges or handles to see if it aids. Another thing that you can try is to replace the gaskets. This can increase the efficiency of your windows and prevent them letting in draughts and cold air. These are available at a hardware store or on the internet. They are easy to install. You can ask a professional if you don't want to tackle it yourself.

If you've got condensation between the window panes, this is also a situation that can be easily fixed. It is caused by an unsound window seal that allows moisture to get in between the glass panes. This could cause the glass to fog up, which is unsightly and ineffective.

Anyone with a little DIY experience can easily swap out gaskets. It is essential to ensure that you make use of a gasket sealer which will give you a strong seal and will help reduce energy bills. You can also use a calk for filling any gaps and give your windows an extra boost in their weatherproofing.

The seals can also fail on double-glazed windows. This can happen due to paint being used near the windows, renovation work or even just general wear and wear and tear. It is crucial to repair your double-glazed windows as soon as they become misted.
