Double Glazed Windows Repairs

As time passes, your double glazed windows will begin to show signs that they need repair. Some of these signs include drafts entering the window or misting and condensation on the windows.

You can solve these problems without having to replace your entire window unit, and save money on your energy bills.

Broken Panes

A pebble from a lawnmower, a baseball toss by your children or even an accident at work could cause a crack in the glass of your double-glazed window. Unlike single-pane windows, double glazing features an airtight seal that keeps insulated gas between two glass panes. If a broken glass pane leaves a gap in your frame, you'll need to replace it.

In a few easy steps, you can put in the new window pane. First, the old glass and the wood surrounding it must be removed from the frame. Then, the new glass is inserted into the frame's opening and then pressed in place using silicone caulk.

The gap in the frame is then filled with window putty which can be spread around with a putty knife and smoothed by a second knife. Window putty can also be used as an adhesive, which helps to hold the new pane in place. If the wood moldings on the double-glazed windows are painted, you will need to use an axe to remove the excess varnish or paint.

Make sure you wear thick gloves when working with glass before installing a new window. Then, scrape away any window glass that remains with a utility knife and determine the opening for the new windowpane. With a wood frame, remove 1/16 of an inch from each measurement to allow expansion and contraction of the wooden frame. The same procedure should be followed with metal frames to ensure a secure fit of the replacement glass.

It is possible that the seals in between the glass panes can also become faulty during the repair of double-glazed. This could result in condensation or mist forming in the gap. A technician can fix this issue by drilling tiny holes into the frame to eliminate any moisture. He or she can then pipe hot air into the gap to dry it and seal it.

Although you can repair double-glazed windows yourself, it is normally better to let professionals handle the job. Special tools are required to take out and install the new glass, so the job should only be handled by a certified expert to avoid any injuries.

Foggy Windows

The window seal (also known as the gasket for windows) is responsible to seal air between the two panes of glass in double glazing and preventing drafts, moisture and noise. Over time the window seal may shrink or become brittle. This is due to natural expansion and contraction when the window experiences different temperatures and weather conditions throughout the year.

Foggy windows can be a sign of a failing airtight seal. This allows moisture from the outside to penetrate and build up in between the glass panes, giving an appearance of frosted, wet which is difficult to clean.

There is a way to fix the problem without removing double-glazing. One option is to "defog the window by drilling tiny holes and injecting a cleaning solution between the glass panes. However, this is a short-term fix as the solution only removes the fog, but it does not replace the inert gas between the glass and restore energy efficiency that may be lost due to degrading seals.

Another alternative is to replace the glass with an insulated glass unit (IGU). This will give you clean, clear windows that are free of fog and will restore any energy efficiency. This will cost more than just fixing the IGU, but it is a more permanent solution.

It is possible that the frame of your door or window may be rotting. This could need replacement. This is a major repair job and could be costly however, replacing the rotten frames will give you a new start and stop the entry of more moisture into your home. If you do decide to replace the window, it's best to have a professional come out and assess the damage prior to making any repairs. They will give you a quote and advise you on the best options. They can help you choose the best double-glazing system that will fit perfectly. They will then install your windows in a proper manner and use top quality materials.

Condensation between the Panes

Condensation occurs when warm air comes in contact with an icy surface. Air vapour is able to condense into, forming liquid droplets. Condensation on windows with double-glazed glass can be easily wiped away. However, the moisture that is trapped between the panes may cause mould to develop or even damage the glass.

The moisture that builds up between the windows in your home could be the result of a variety of problems, including temperature variations or high humidity levels, as well as damaged seals. Older windows are more susceptible to this issue than newer ones with better sealing technology.

It is important to note that although the development of condensation on the glass of your window should not be ignored, this can easily be fixed without having to replace the entire unit. In many instances this problem, it is caused by an issue with the vacuum or gas seal that is located around the inner and outer frames of your windows.

A professional can inspect your window and determine if the seals need to be repaired or replaced. If  double glazing repairs Ascot  require to be replaced they will make your windows more efficient in to insulate cold or heat, resulting lower energy costs.

A specialist can employ a drill to cut holes in both the inner and outer windows to remove the moisture that has accumulated within. It can take from one to three days for the moisture to completely evaporate out of the window. Once this is done the window can then be re-sealed and fitted with vents that allow the windows to naturally eliminate moisture and air.

The best way to avoid this problem entirely is to ensure that your windows are sealed and maintained regularly to prevent the seals from degrading. This can be accomplished by enlisting a professional to conduct a regular maintenance service for your double glazing. This will allow you to spot any issues early and address them before they get worse, which will prolong the lifespan of double-glazed windows.

Damaged Frames

Sometimes, the frames of double glazing may develop problems which need repairing. These will need the expertise of a professional. They are much cheaper than replacing the windows. They are also more energy efficient.

One of the most frequently encountered problems is when water gets into the frame of a double-glazed unit and creates condensation. This happens because the seal made of rubber that keeps the insulating gap free of water breaks down and tiny holes begin to appear. It can happen due to many reasons. Most commonly the seals wear out or a small amount water gets trapped between the panes.

The first thing to do should you encounter this issue is to contact the company you purchased your double glazing from. They will examine the issue and, if the problem is covered under warranty, they will arrange to have the unit replaced for you.

It is important to remember that this process can take a while, based on how busy the company is. It is crucial to learn all you can about the company, the installers and their services before signing the contract. This will help you avoid any problems later on and ensure that your repairs are done correctly.

A specialist can repair the gasket seals which have shrunk and cracked to stop condensation and moisture from forming between the panes of glass. This is a less expensive alternative to installing double glazing windows that can cost thousands of pounds. This is more sustainable for the environment, and you'll save money on energy bills.


In certain situations the frame of a window might require replacement completely. This could be because of damage or if windows have become old and not energy efficient anymore. If the window is beyond repair, it is recommended to replace it with the same model. This will increase the energy efficiency of your house and will prevent any future issues caused by leaks and condensation.
