Double Glazed Windows Repairs

There are a variety of reasons your double-glazed windows may need repairs, from condensation between panes, to drop or sagged frames. Many of these issues can be solved.

If your door or window is difficult to open try oiling the mechanism, hinges and handles. This is a simple, affordable fix.

Broken Panes

When a window pane breaks it loses its insulation properties and may cause draft. If the muntins which divide the glass panes are also broken, moisture can leak between them causing condensation or mildew, or mould. This makes your home less energy-efficient. It is recommended to have a professional repair a broken window to ensure the best seal and energy efficiency.

The first step is to remove any broken glass. Begin by placing a protective drop cloth beneath the broken window, and then cutting around the perimeter of the pane with an inexpensive glass cutter (available in most hardware stores). It's recommended to lubricate the cutter with lightweight oil before you begin. This will stop the glass from shattering too easily. You can then use the tool's ball-shaped end to break up the glass fragments, which should come away quickly.

After the glass has been removed, scrape away any old glazing compound from the recess of the frame. This will reveal the glazier's points and the metal clips that hold the pane in place. If there's evidence of corrosion, these clips should be replaced with new ones. If the window is made of wood the glazier points can be reused if still intact.

The remaining frame needs to be prepared for reflazing. Apply a continuous strip of compound to the recess with the caulking tool. Make use of a premium putty like glazier's compound that is available in a cartridge or a conventional compound sold in a can. It should dry before installing the glass. If the frame is made of metal clippings, they should be replaced as well. Install the dividers.

Condensation

Condensation is one of the most common issues that double-glazed windows face, especially in the winter months. It's usually caused by too many levels of moisture in your home. Warm air collides with cold glass, which condenses into water droplets. They then settle in the corners and frame of the window. You can avoid this by opening your windows more frequently and enhancing ventilation by installing extractor fans, and using dehumidifiers. If condensation persists, you should call a professional who can diagnose the issue and fix or replace the windows if necessary.

It's also important to note that condensation on a double-glazed window can actually be an indication of a leaky seal. This is because the factory-applied vacuum seal can become degraded in time and allow cool air to move between the panes. This can lead to fogging of the window and eventually mold growth if not addressed quickly enough.

Hairdryers can be used for a quick way to get rid of excess moisture. This is only a temporary solution and should only be used as a last alternative. If you leave the condensation for too long, it could lead to mould or dampness in your home. This should be dealt with by a professional.

As a long-term solution, you can get your double-glazed windows sealed by professionals. They'll remove the affected pane of glass, clear the gap and pipe in hot air to evaporate any remaining moisture. During the process, they'll also look for any damage or growth of mould, mildew or mildew and then perform an air draughtproofing treatment to ensure that your windows are functional and energy-efficient once again.

Draughts

As time passes by, the rubber seals around the edges of your insulated glass can fall apart and create a draught in space between the two panes. This is often a simple problem that can be solved by replacing the gaskets and this will result in a sturdy and airtight seal. This will keep warm air inside your home, and colder air outside. You will reduce your energy bill.

Double glazing that is misted could be a sign of blown seals. The unit is comprised of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal is blown the water vapour will get into your space through the gap. This will create condensation between the glass panes that can't be sucked out.

Fortunately it is a simple problem to fix, and the windows can be replaced quickly by specialists who have the appropriate tools and know how to do it properly. The expert will employ an instrument that is designed to push into the new seals. This is generally faster than doing it manually. The tools also come with a pointed end which can be useful for pushing seals into the corners.

In some cases an expert might be able to "reseal your windows' by drilling a small hole in the window and then adding the desiccant material, or putty. This could be a more cost-effective solution than replacements, and will offer a reliable draught-proofing system for double glazing.

Faulty Hinges

Many people have experienced misted double glazing. It could be caused by a broken or cracked glass frame, or even a broken seal. The good thing is that this can often be repaired. This usually involves creating a seal between two glass panes. The new seal will stop leaks, condensation and draughts from happening.

As soon as you notice any issues, you must contact the company that sold you the windows. Be sure to do this in writing and ask them to confirm that they have received your message. If there is a dispute the fact that everything is written will help you prove your case.

In some instances the window repair expert will cut the hole in your windows to draw out moisture and create an entirely new seal. This is only temporary and will not stop moisture from returning. Alternatively, it may be possible to replace the glass unit, to ensure that it is watertight.

It is important to keep in mind that you should only attempt DIY fixes when you have the skills and experience required to be able to do it. Super glue or other DIY solutions could cause more damage over the long term. If you aren't sure what to do, it is always advisable to seek out professional advice.

Broken Seals

Double-glazed windows are held in place by window seals or insulation gas. They are susceptible to damage due to a variety of factors, such as weather conditions, age, and power washing. It is essential to be aware of the signs and the best way to upvc repair them.

When a window seal fails humid air can leak between the two panes glass, creating fog. This is a common issue, and can cause the window to look visually distorted. When the seal fails, any argon or other inert gas is removed from the glass, further diminishing its insulating properties.

A broken window seal can be repaired by having it replaced with an entirely new one by a professional glazier. However, this could be costly and might not resolve the fog issue completely. Certain companies offer defogging solutions that involve putting the vacuum pump of a specific type inside the window frame to eliminate the moisture and make the glass clear. However, this method is not 100% reliable and cannot replace any inert gases, meaning that the fog can return.

A glazier can also replace the entire IGU (insulated glass unit) if it is beyond repair. This is typically the most cost-effective solution and can be a good choice in the event you're looking for a long-term solution. It is recommended to choose an option that provides warranties on replacement windows. This will ensure that any issues you might face are covered. You can be assured that your investment will produce the most effective results. You can also avoid the problem by selecting a high-quality product and following the care instructions provided by the manufacturer. This will prolong the life of the window and decrease the amount of repairs.
