Broken Panes

If a window pane is damaged it loses its insulation and can cause a draft. If the muntins that divide the glass panes are broken, water can leak between them causing condensation or mildew, or mould. This will make your home less efficient in energy use. A damaged window should be repaired by a professional to ensure you get the correct seal and the optimum energy efficiency.

First, you will need to take out any broken glass. Start by placing a low-cost glass cutter in an hardware store underneath the broken pane. Before starting, you should grease the cutter of this tool using a light oil. This will help prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to loosen the pieces. They should come off relatively quickly.

Scrape any old glazing compound out of the recess of the frame once the glass has been removed. This will reveal the glazier's facets and metal clips that keep the pane in the frame. Replace them if there's any corrosion. If the window is made of wood the glazier's points could be re-used if they're still intact.

The next step is to prepare the surface of the frame to be re-glazed. Apply a continuous strip compound to the recess with a caulking tool. Make use of a high-quality glue such as glazier's compounds that is contained in a cartridge, or a standard compound that comes in a tin. Let it dry before installing the glass. If the frame has metal clippings, these should be removed as well. Install the dividers.

Condensation

Condensation can cause problems for double-glazed windows, particularly during winter. It's usually caused by too many levels of moisture within your home. Warm air is absorbed by cold glass and condenses into water droplets. These droplets then accumulate in the corners or frame of the window. It can be prevented by opening windows more regularly, improving ventilation through extractor fans and running dehumidifiers to reduce moisture levels. If condensation remains an issue, it's best to contact an expert to get to the root of the issue and repair or replace your windows as needed.

Condensation on a double-glazed window is a sign the seal has failed. This is due to the factory applied vacuum seal will break down over time and allow cool air to move between the panes. This can cause the window to become cloudy and then develop mold if it's not addressed immediately.

As a quick fix for condensation, try using hair dryers to dry the excess moisture. But, this is only temporary solution and should be used as the last option. If the condensation has been allowed to sit for too long it may be experiencing mould or dampness in your home, which should be addressed by a professional.

For a more long-term solution you can get your double-glazed windows sealed by professionals. They'll remove the affected pane of glass, clear the gaps and pipe in hot air to evaporate any moisture that remains. During the process, they will also check for any damages or growth of mildew, mould or mildew, and perform an draught-proofing procedure to ensure that your windows are efficient and energy efficient once more.

Draughts

Rubber seals may wear down over time and cause drafts between your two panes. It is an easy fix to replace the gaskets, which will result in an airtight seal. This will keep warm air inside your home and cooler air out. You will reduce your energy bills.

Misted double glazing indicates that the seals inside your sealed unit (sometimes called a DGU) have blown. The unit is comprised of two glass panes filled with argon separated by a spacer to form an airtight window. If the seal has blown the water vapour will get into your home through the gap. This can result in condensation between the glass panes which cannot be removed.

Fortunately it is a simple issue to fix and windows can be replaced very quickly by professionals with the right tools and know how to do it correctly. The specialist will use an instrument designed to push into the new seals. This is usually quicker than doing it manually. These tools have an edge that can be used to push seals into corners.

A professional might be able to reseal your windows by drilling a small opening in the window, and then adding a desiccant or putty. This is a more cost-effective solution than replacements, and will offer a reliable protection against draughts for your double glazing.

Faulty Hinges

Misted double glazing is a frequent problem that many people encounter. It may be caused by a damaged seal or a crack in the glass, or a problem with the frame or mechanism. The good thing is that this can be easily solved. This typically involves making a seal between the two glass panes. The new seal will stop condensation, draughts, window repair as well as leaks.

If you spot any problems, you should contact the company that sold you the windows. Be sure to do this in writing, and ask them to confirm that they've received your notification. Making sure that everything is in writing will make it easier to resolve any disputes arise, since it will be easier to prove that you did indeed complain.

In certain situations, a window repair specialist will drill the gap in your windows to draw out moisture and create the new seal. However, this is usually only a temporary solution and will not prevent moisture from returning. It is also possible to replace the glass unit, which will ensure that it is watertight.

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

Broken Seals

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

When a window seal fails, humid air can seep between the two panes of glass, creating fog. This is a frequent issue that can cause the window appear to be distorted. When the seal is damaged, gas like argon as well as other inert gases are removed from the window, decreasing the glass's insulation properties.

A damaged window seal can be fixed by replacing it with an entirely new one by an experienced glazier. This is costly and may not completely solve the fog issue. Some companies offer defogging which involves putting an air-pump inside the frame of the window to remove moisture and make the glass clear. This method is not foolproof, and it doesn't replace inert gasses, so the fog could return.

If the IGU (insulated unit) is damaged beyond repair, a glazier can replace it. This is usually the most cost-effective solution and is a great option when you're looking for a long-term solution. However, it's best to select a company that offers a warranty for replacement windows to ensure that any issues are covered. This way, you can rest assured that you'll get the most value from your investment. You can also avoid this issue by choosing an item of high-quality and following the care guidelines given by the manufacturer. This will prolong the life of the window and reduce the number of repairs.
