Double Glazed Windows Repairs

There are many reasons why your double-glazed windows may require repairs such as condensation between panes to drop or sagged frames. Many of these issues can be solved.

Try applying lubrication to the hinges, handles and mechanisms of your window or door when it is difficult to open. This is usually a low-cost temporary fix.

Broken Panes

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

The first step is to take out any broken glass. Begin by placing a protective drop cloth under the broken window, and then scoring around the perimeter of the pane with an inexpensive glass cutter (available at most hardware stores). It's worth lubricating this tool's cutter with lightweight oil before you begin. This will stop the glass from breaking too easily. You can then use the tool's ball-shaped end to loosen the fragments and they should fall away quickly.

Scrape any old glazing compound out of the recess of the frame once the glass is removed. This will expose the metal clips and glazier's pins that keep the glass in place. Replace them if there's any corrosion. If the upvc window repairs is constructed of wood the glazier points can be reused if they're still in good condition.

The remaining frame needs to be prepared to allow re-glazing. Apply a continuous strip of compound to the recess using the caulking tool. Use a high quality putty such as a Glazier's compound in a cartridge. It should dry before reinstalling the glass. Install the metal clips if they are on the frame. Then, you can put back the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, especially during the winter. It's usually caused by too much moisture in the house where warm air collides with cold glass, which then condenses into water droplets and then collects in the corners of your windows or across the frame. This can be prevented by opening windows more regularly and enhancing ventilation with extractor fans and running dehumidifiers in order to reduce the amount of moisture. If condensation is still an issue, it's best to contact an expert to determine the bottom of the issue and repair or replace your windows when necessary.

Condensation in a double-glazed glass window is a sign that the seal has failed. The seal that is applied by the factory can wear out over time and allow cool air to pass between the panes. This can cause fogging of the window and eventually, mold growth if it is not addressed promptly enough.

Hairdryers can be used to get rid of excess moisture. However, this is just an interim solution and should only be used only as a last option. If you leave the condensation 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 to provide a longer-lasting solution. They'll remove the affected pane of glass, clean out the gap and pipe in hot air to evaporate any moisture that remains. In this process, they'll look for signs of the presence of mildew, mold or damage growth and carry out a draught-proofing treatment to ensure your windows are fully operational and energy efficient again.

Draughts

Rubber seals can get worn out in time and create a draft between your two panes. This is usually a minor problem that can be solved by replacing the gaskets and this will result in a solid and airtight seal once again. This will keep warm air inside your home, and cooler air out. You'll reduce your energy bills.

Misted double glazing is a sign the seals in the sealed unit (sometimes called a DGU) have blown. The unit is made up of two panes of glass that are separated by the spacer bar to create an insulating space. It is then filled with gas, such as argon, to make the window airtight. If the seal has been blown the water vapour will get into your home through the gap. This can cause condensation between the glass panes that can't be sucked out.

Fortunately, this is an easy problem to fix, and the windows can be replaced quickly by experts with the right tools and know how to do it right. The expert will employ an instrument designed to push in the new seals. This is usually quicker than doing it by hand. These tools also come with a pointed end which is useful for pushing the seals into the corners.

In certain cases professionals could be able to "reseal' your windows by drilling a small opening into the window and then putting in the desiccant material, or putty. This is an economical alternative to replacements and it will still offer a reliable protection against draughts for double glazing.

Faulty Hinges

Misted double glazing is a typical problem that many people experience. It may be caused by a broken seal or a crack in the glass, or an issue with the frame or mechanism. It is possible to correct this issue. Usually, this means making a new seal between two panes of glass. The new seal will stop condensation, draughts and leaks.

If you spot any issues, you must contact the company that sold you the windows. You should inform the company in writing and ask for confirmation that they have received your notice. If there is a dispute the fact that everything is written will help you prove your complaint.

In some instances an expert in window repair may be able to drill a hole in your windows to draw out moisture and make a new seal. However, this is generally only temporary and will not stop the return of moisture. It might also be possible to replace the glass, which would make it watertight.

It is crucial to remember that you should only experiment with DIY fixes when you have the skills and know-how required to be able to do it. Super glue or other DIY solutions could cause more permanent damage. It is best to seek out professional assistance when you aren't sure what to do.

Broken Seals

Window seals, also known as insulation gas fills, are what hold double glazed windows in place. Many factors can cause them to break, such as the weather, age, and power washing, therefore it's important to know what the signs are and how to fix them.

When a window seal fails it allows moisture to enter between the two glass panes and create fog. This is a common problem that can make the window appear distorted. Once the seal fails, any argon or other inert gas is lost from the glass, thereby reducing its insulating properties.

A damaged window seal can be repaired by having it replaced with the new one by an experienced glazier. This is costly and might not be able to resolve the fog issue. Some companies offer defogging services which include putting the vacuum pump of a specific type inside the window frame to remove the moisture and leave the glass clear. This method isn't 100% reliable, and it doesn't replace inert gasses, so the fog can come back.

A glazier can also replace the entire IGU (insulated glass unit) if it is beyond repair. This is the most cost-effective option and is a good choice if you are looking for a long term solution. But, it's best to select a company that offers a warranty for replacement windows to ensure that any problems are protected. You can be assured that your investment will produce the best results. You can also get rid of the issue by choosing the best quality product and following the care instructions that are provided by the manufacturer. This will prolong the life of the window and reduce the number of repairs.
