Double Glazed Windows Repairs

There are many reasons your double glazed windows might need repairs, from condensation between panes, to drop or sagged frames. Thankfully, most of problems can be addressed.

If your window or door is difficult to open, consider oiling the hinges, mechanism and handles. This is usually a cheap, short-term fix.

Broken Panes

When a window pane is broken, it loses its insulating properties and could cause draft. If the muntins that divide the glass panes also damaged, moisture could get in between them and cause condensation, mould or mildew. This makes your home less energy-efficient. It is recommended to hire a professional repair the damaged window to ensure the best seal and energy efficiency.

First, you'll need to take the broken glass off. Start by placing an inexpensive glass cutter from a hardware store under the broken pane. It's a good idea to grease the cutter with lightweight oil before you begin. This will prevent the glass from shattering too easily. The ball-shaped end of the tool can be used to loosen the pieces. They should come off relatively quickly.

After the glass has been removed, scrape off any old glazing compound from the recess area of the frame. This will expose the glazier's clips and pins that keep the glass in place. If there's any sign of corrosion, these clips should be replaced with new ones. If the window is constructed of wood, the glazier points can be reused if they're still in good condition.

You'll need to prepare the surface of the frame for re-glazing. Utilizing a caulking gun apply a continuous strip of compound around the inner edge of the recess. Use a high-quality putty, such as a glazier’s compound in a cartridge. Let it dry before installing the glass. Reinstall the metal clips if they are on the frame. Finally, reinstall the divider muntins.

Condensation

Condensation is one of the most common issues that double-glazed windows face, especially in the winter months. It's typically caused by too much moisture in the home where warm air collides with cold glass, which forms 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 frequently and improving ventilation with extractor fans, and using dehumidifiers. If condensation continues to occur, you should call a professional who can diagnose the problem and repair or replace the windows if needed.

It's also important to remember that condensation on a double-glazed window could be a sign of a failing seal. This is because the factory-applied vacuum seal may become degraded in time and allow cool air to make its way between the panes. This can cause fogging of the window, and eventually mold growth if not addressed promptly enough.

As a quick fix for condensation, you can try using a hairdryer to dry up the excess moisture. However, this is only an interim solution and should be used only as the last option. If you let the condensation sit for too long, it may cause dampness or mould in your home. This should be handled by a professional.

Professionals can reseal double-glazed windows for a more permanent solution. They'll remove the affected piece of glass, clear the gaps and pipe in hot air to evaporate any lingering moisture. During this process, they'll also check for damage, mould or mildew growth and carry out a draught-proofing treatment to ensure that your windows are fully operational and energy efficient again.

Draughts

As time goes by the rubber seals around the edges of your glass insulated can break down and this can create a draught in the space between the two panes. It's simple to replace the gaskets which will create an airtight seal. This will keep warm air inside your home, and cooler air out. You will reduce your energy bill.

Misted double glazing is a sign that the seals in the sealed unit (sometimes called a DGU) have been blown. The unit is composed of two panes of glass filled with argon separated by a spacer to form an airtight window. If the seal is blown it will allow water vapour to get into your space through the gap, creating condensation between the panes which can't be removed.

Fortunately it is a simple problem to fix and the windows can be replaced quickly by specialists who have all the right tools and know how to do it correctly. The professional will employ an instrument designed to push in the new seals. This is typically faster than doing it manually. These tools feature a pointed tip that can be used to push the seals into corners.

A professional might be able to reseal your windows' by drilling a small gap into the window, and then adding a desiccant or putty. This could be an economical alternative to replacements, and will offer a reliable draught-proofing system for your double glazing.

Faulty Hinges

Misted double glazing is a frequent problem that many people experience. It could be caused by a broken seal or a crack in the glass or an issue with the frame or mechanism. The good news is that it is often solved. This typically involves creating a seal between two glass panes. The new seal will stop condensation, draughts and leaks.

Contact the company from which you purchased your windows, and inform them of any problems immediately you discover them. Make sure to put this in writing and ask them to confirm that they've received your notification. If there are any disputes the fact that everything is written will make it easier to prove your claim.

A window repair expert may drill the gap between your windows in order to eliminate moisture and make a seal. However, this is generally only a temporary fix and will not prevent the moisture from returning. Alternatively, it may be possible to replace the glass unit, which will ensure that it is watertight.

Broken Seals

Window seals, or insulation gas fills, are what keep double glazed windows in place. They can be damaged by a variety of elements, including age, weather conditions, and power washing. It is essential to recognize the signs and the best way to repair them.

When a window seal fails, it allows humid air to seep in between the two glass panes, causing fog. This is a frequent issue that can also make the window appear disfigured. Once the seal fails it is when any argon or other inert gas will be removed from the glass, decreasing its insulation properties.

A professional glazier can repair a damaged window seal with a new one. However, this could be expensive and may not solve the fog problem entirely. Some companies offer defogging services, which involve placing a special vacuum pump in the window frame to remove the moisture, leaving the glass clear. This method isn't foolproof and doesn't replace inert gasses, meaning that fog may be re-created.

A glazier may also replace the entire IGU (insulated glass unit) in the event that it is beyond repair. This is the most cost-effective method and can be a great option if you're seeking 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. You can be sure that your investment will yield the most effective results. You can also try to avoid this issue by choosing a high-quality window and following the manufacturer's maintenance instructions. This will prolong the lifespan of the window and reduce the amount of repairs.
