Double Glazed Windows Repairs

There are many reasons your double-glazed windows may require repairs, from condensation between panes to drop or sagged frames. Most of these problems can be resolved.

Try applying lubrication to the hinges, handles and mechanisms of your window or door in case it is hard to open. This is usually a cheap temporary fix.

Broken Panes

If a window pane breaks, it loses its insulation properties and could cause draft. If the muntins that separate the glass panes are also broken, water can get in between them and cause condensation or mildew, or mould. This will make your home less energy efficient. A broken window is best repaired by an expert to ensure you get a proper seal and maximum energy efficiency.

First, you’ll need to remove the broken glass. Start by placing a protective drop cloth underneath the broken window doctor, and then scoring around the perimeter of the pane with an inexpensive glass cutter (available in a majority of hardware stores). Before starting, you should lubricate the cutter of this tool with a light oil. This will stop the glass from breaking too easily. The ball-shaped tool can be used to break the fragments. They should be removed quite quickly.

Scrape any old glazing compound off the frame’s recess once the glass has been removed. This will expose the glazier’s point and metal clips that hold the pane in the frame. Replace them if you notice any corrosion. If the window is made of wood the glazier’s gilder’s points can be re-used if they’re still intact.

You’ll then need to prepare the surface of the remaining frame for reglazing. Using a caulking gun, apply a continuous ribbon of compound around the inside edge of the recess. Make use of a high-quality glue like glazier’s compound that is available in a cartridge or a conventional compound that is sold in a can. It should dry before installing the glass. If the frame has metal clippings, they should be reinstalled too. Then, you can install the dividers.


Condensation is a concern for double-glazed windows, especially during the winter. It’s usually caused by too much humidity in the home where warm air collides with cold glass, which condenses into water droplets and then collects in the corners of your windows or across the frame. You can avoid this by opening your windows more often and improving ventilation with extractor fans, and running dehumidifiers. If condensation is still present it is recommended to contact a professional who can diagnose the issue and repair or replace the windows if needed.

Condensation on a double-glazed glass window is a sign the seal has failed. This is due to the vacuum seal that was applied by the manufacturer can break down over time, Double glazing allowing cool air to flow between the panes. This can cause the window to become cloudy and eventually develop mold if it’s not addressed quickly.

As a quick fix for condensation, you can try using hair dryers to eliminate the excess moisture. However, this is just a short-term solution and should only be only used as an option last resort. If you let the condensation sit for too long, it could cause dampness or mould in your home. This issue should be handled by a professional.

As a long-term solution, you can get your double-glazed windows sealed by experts. They will remove the affected glass pane and clean the gap. They will then pipe hot air into the gap to dry out any moisture. During the process, they’ll also inspect for any damage or growth of mould, mildew or mildew and apply an air draughtproofing treatment to ensure that your windows are functional and energy efficient.


As time goes by the rubber seals around the edges of your glass insulated can break down and this can create a draught in space between the two panes. This is usually a minor issue that can be resolved by replacing the gaskets and this will create a strong and airtight seal. This will keep the warm air inside your home, and the colder air outside, saving you money on your energy bills.

Misted double glazing is a sign that the seals inside your sealed unit (sometimes called a DGU) have blown. The unit is made up of two panes of glass separated by the spacer bar to create an insulating space. It is then filled with gas, like argon for example, to make the window airtight. If the seal is blown it allows water vapour to get into your space through the gap, which will cause condensation between the panes that can’t be removed.

Fortunately it is a simple issue to fix and windows can be replaced very quickly by specialists with the right tools and know how to do it properly. The professional will employ an instrument that is designed to push into the new seals. This is generally faster than doing it manually. The tools have an angled tip that can be used to push the seals into corners.

A professional might be able to reseal your windows’ by drilling a small hole into the window and then adding a desiccant or putty. This is a more cost-effective solution than replacements, and will offer a reliable draught-proofing solution for your double glazing.

Faulty Hinges

Many people have experienced misted double glazing. It can be caused by broken or cracked glass frame or even a damaged seal. It is often possible to fix this problem. Typically, this is done by creating an entirely new seal between the two panes of glass. The new seal will stop condensation, draughts and leaks.

If you discover any issues, you must contact the company that sold you your windows. Make sure you do this in writing, and request them to confirm that they’ve received your message. Having everything in written form will make it easier to resolve any disputes arise, as it is easier to prove that you actually complained.

In some cases the window repair expert will cut the hole in your windows to draw out moisture and make a new seal. This is a temporary fix and won’t stop the return of moisture. It is also possible to replace just the glass, which would make it watertight.

It is important to keep in mind that you should only attempt DIY fixes if you have the skills and knowledge necessary to make the attempt.

Broken Seals

Window seals, also known as gas fills, keep double glazed windows in place. They can be damaged by many factors, including weather conditions, age and power washing. It is important to know the symptoms and the best way to repair them.

If a window seal is damaged, it allows humid air to enter between the two glass panes and create fog. It’s a common problem, and can cause the window to appear visually distorted. When the seal is damaged, gas like argon as well as other inert gases are lost from the window, thereby reducing the glass’s insulating qualities.

A professional glazier can repair a damaged window seal with a brand new one. However, this could be costly and might not resolve the fog issue completely. Certain companies offer defogging, which involves putting an air pump inside the window frame to remove moisture and make the glass clear. This method is not foolproof and does not replace the inert gasses, so the fog could return.

If the IGU (insulated unit) is damaged beyond repair, a glazier could replace it. This is typically the most cost-effective solution and is a great option if you’re seeking the long-term solution. However, it’s best to select a company that offers a warranty for replacement windows to ensure that any issues are protected. This way, you can rest assured that you’ll get the most out of your investment. You can also try to avoid this issue by choosing a high-quality product and following the maintenance instructions that are provided by the manufacturer. This will extend the life of the window and cut down the amount of repairs.
