Double Glazed Windows Repairs

There are a variety of reasons your double-glazed windows could require repair such as condensation between panes, to dropping or sagging frames. Most of these problems can be solved.

Try to lubricate the hinges, handles and mechanisms of your window repairs or door if it is difficult to open. This is a simple, cheap solution.

Broken Panes

When a window pane is damaged and shattered, it loses its insulation properties and can cause a draft. If the muntins which divide the glass panes are broken, water can be leaking between them, causing condensation and mildew, as well as mould. This will make your home less energy efficient. It is recommended to hire a professional repair the damaged window in order to get the most effective seal and energy efficiency.

First, you will need to take out any broken glass. Begin by placing a cheap glass cutter from a hardware store under the broken pane. It's recommended to lubricate the cutter with lightweight oil before you begin. This will stop the glass from breaking too easily. You can then make use of the tool's ball-shaped tip to loosen the fragments and they should fall away fairly quickly.

Once the glass is removed, scrape any old glazing compound that has accumulated in the recess of the frame. This will reveal the glazier's facets and metal clips that keep the pane in place. Replace them if there is any corrosion. If the window is made of wood the glazier points may be reused if still in good shape.

You'll then need to prepare the surface of the remaining frame for reglazing. Apply a continuous strip compound to the recess with the caulking tool. Use a high quality putty, such as a glazier’s compound in a cartridge. Dry it out before reinstalling the glass. If the frame is made of metal clippings, they should be removed as well. Then, you can reinstall the divider muntins.

Condensation

Condensation can be a problem for double-glazed windows, particularly during the winter. It's typically caused by excessive moisture in the house as warm air meets cold glass, which then condenses into water droplets and collects in the corners of your windows or across the frame. You can stop this from happening by opening your windows more often and enhancing ventilation by installing extractor fans, and using dehumidifiers. If condensation is still an issue, it's crucial to call in an expert to determine the bottom of the issue. You can then fix or replace your windows when needed.

It's also important to note that condensation on double-glazed windows could be a sign of a leaky seal. The seals that are applied at the factory may wear away over time and allow cool air to pass between the panes. This can lead to fogging of the window and eventually, mold growth if not dealt with quickly enough.

A hairdryer can be used to eliminate excess moisture. This is only a temporary solution and should only be used as a final option. If the condensation is left for too long, you could be looking at dampness or even mould in your home, which must be dealt with by a professional.

Professionals can reseal your double-glazed window for a better, more durable solution. They'll take off the affected glass pane, clean the gap and pipe hot air into the gap to evaporate any moisture. In this process, they'll also check for damage, mould or mildew growth and apply an draught-proofing procedure to ensure your windows are fully operational and energy efficient again.

Draughts

The rubber seals wear out over time and create drafts between the two panes. This is usually a minor problem that can be fixed by replacing the gaskets and this will result in a sturdy and airtight seal once again. This will keep warm air inside your home, and colder air outside. You can reduce your energy bills.

Double glazing that has mist could be a sign of blow-blown seals. The unit is comprised of two panes of glass separated by an insulating bar that creates an insulating space. It is then filled with gas, for example argon, to make the window airtight. If the seal is blown it will allow water vapour to pass through your home through the gap, creating condensation between the panes which cannot be wiped off.

This is a simple problem to fix, and windows can be swiftly repaired by professionals using the right tools. The expert will employ tools designed to push the new seals into position and it is usually faster than trying to do it by hand. The tools also have a pointed tip which is useful for pushing seals into the corners.

In some cases, a professional might be able to "reseal' your windows by drilling a small hole into the window and then putting in a special desiccant material or putty. This is less expensive than replacing your double-glazed windows and will still provide you with an effective air-tight system for draughtproofing.

Faulty Hinges

Many people have encountered misted double-glazing. It can be caused by a damaged seal, or a crack in the glass, or a problem with the mechanism or frame. The good thing is that this can often be solved. This usually involves making a seal between the two glass panes. The new seal will help prevent condensation, draughts and leaks.

Contact the company from whom you bought your windows and let them know of any problems when you discover them. Make sure you do this in writing, and request them to confirm that they have received your notification. If there are any disagreements being resolved, writing everything down will aid in proving your complaint.

In certain situations, a window repair specialist will drill the gap in your windows to draw out moisture and create a new seal. However, this is usually only a temporary solution and won't stop the moisture from returning. Alternatively, it may be possible to replace the glass unit itself which will ensure that it is watertight.

Make sure that you only try DIY fixes only if your skills and experience are adequate. Utilizing super glue or any other kind of DIY solution could cause more damage in the long run. If you aren't sure what to do, it is always better to seek professional advice.

Broken Seals

Double glazed windows are held in place by window seals or insulation gas. They are susceptible to damage due to many elements, including weather conditions, age and power washing. It is crucial to recognize the signs and how to fix them.

If a window seal is damaged, humid air can seep between the two panes glass, causing fog. This is a common issue, and can cause the window to appear visually distorted. When the seal is damaged, the inert gases argon and others are lost from the window, thereby diminishing the glass's insulation capabilities.

A damaged window seal can be fixed by replacing it with a new one by an experienced glazier. However, this can be expensive and may not resolve the fog problem entirely. Some companies offer defogging, which involves placing a vacuum pump inside the frame of the window repairs to eliminate moisture and make the glass clear. This method is not foolproof, and it does not replace inert gasses, which means that the fog could be re-created.

If the IGU (insulated unit) is beyond repair, a glazier can replace it. This is usually the most cost-effective option and can be a good choice when you're seeking the long-term solution. It is recommended to choose a company who offers a warranty on replacement windows. This will ensure that any issues that you might encounter are covered. This way, you can rest sure that you'll get maximum value for your investment. You can also try to avoid this issue by choosing a high-quality product and following the maintenance instructions provided by the manufacturer. This will help to prolong the lifespan of your window and decrease the need for repairs.
