Double Glazed Windows Repairs

Double-glazed windows require repair for many reasons, like condensation between the panes, draughts or sagging frames. The majority of these issues are fixable.

If your door or window is difficult to open, consider oiling the mechanism, hinges and handles. This is usually a low-cost solution that is quick and easy to fix.

Broken Panes

When a window is damaged it loses its insulation properties and may cause drafts. If the dividing muntins are broken it can cause moisture to escape between the glass panes resulting in condensation, mildew and mould and making your home less efficient in energy use. It is recommended to hire a professional repair the damaged window to ensure the best seal and energy efficiency.

In the beginning, you'll have to take the broken glass off. Begin by putting a drop cloth under the broken window and then cutting around the perimeter of the pane using an inexpensive glass cutter (available at most hardware stores). It's recommended to lubricate the cutter with lightweight oil before you begin. This will stop the glass from breaking too easily. The ball-shaped tool can be used to loosen the fragments. They should come off quite quickly.

Scrape any old glazing compound from the recess of the frame once the glass is removed. This will reveal the glazier's facets and metal clips that keep the pane in the frame. Replace them if you notice any corrosion. If the window is made of wood, the glazier's points can 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 of compound to the recess with the caulking tool. Make use of a high-quality glue such as a glazier's compound that is available in a cartridge or conventional compound sold in a can. Allow it to dry prior to installing the glass. If the frame has metal clippings, they should be reinstalled too. Finally, reinstall the divider muntins.

Condensation

Condensation can cause problems for double-glazed windows, particularly during the winter. It's typically caused by too much moisture in the home as warm air meets cold glass, which then turns into water droplets, and then collects in the corners of your windows or across the frame. This can be avoided by opening windows more frequently, improving ventilation through extractor fans and running dehumidifiers to lower the moisture levels. If condensation persists, you should call an expert who can identify the issue and repair or replace the windows if necessary.

Condensation on a double-glazed window is a sign the seal has failed. This is because the factory-applied vacuum seal may be damaged in time, allowing cool air to make its way between the panes. This could cause the window to become cloudy and eventually grow mold if it is not addressed promptly.

A hairdryer can be used as a quick solution to get rid of excess moisture. However, this is only an interim solution and should only be only used as a last resort. If you let the condensation sit for too long, it may cause dampness or mould in your home. This should be dealt with by a professional.

Professionals can reseal double-glazed windows to provide a longer-lasting solution. They'll remove the damaged glass pane and clean the gap. They'll then pipe hot air into the gap to eliminate any moisture. In this process, they'll look for signs of the presence of mildew, mold or damage growth, and then apply an draught-proofing procedure to ensure that your windows are fully operational and energy efficient again.

Draughts

As time passes, the rubber seals around the edges of your glass insulated can be damaged and cause a draught to form in the 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 once again. This will keep warm air inside your home, and cooler air outside. You will reduce your energy bill.

Double glazing that has mist may be an indication of blow-blown seals. The unit is comprised of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal has been blown it will allow water vapour to get into your space through the gap, causing condensation between the panes which is not able to be cleaned off.

This is a simple issue to repair, and windows can be easily replaced by specialists with the appropriate tools. The expert will employ an instrument designed to push the new seals in place and is generally faster than trying to do 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 a more cost-effective solution than replacements and will offer a reliable draught-proofing system for your double-glazed windows.

Faulty Hinges

Many people have had misted double glazing. It can be caused by a broken seal or crack in the glass or a problem with the frame or mechanism. It is often possible to fix this problem. Usually, this means creating a new seal between two panes of glass. The new seal will stop condensation, draughts and leaks from occurring.

You should contact the company from which you purchased your windows, and tell them of any problems when you notice them. You should inform the company in writing and demand confirmation that they have received your notice. Making sure that everything is in writing will be helpful later if any disputes arise, since it is easier to prove that you did complain.

A window repair professional may drill the gap between your windows to remove moisture and form the seal. This is only temporary and won't stop moisture from resurfacing. It is also possible to replace only the glass, which would make it watertight.

Broken Seals

Window seals, also known as insulation gas fills, are what hold double-glazed windows in place. They can be damaged by a variety of factors, such as age, weather conditions, and power washing. It is essential to recognize the signs and how to repair them.

When a window seal fails, humid air can seep between the two panes glass, causing fog. This is a common issue that can also make the window appear to be distorted. When the seal fails it is when any argon or other inert gas will be removed from the glass, further diminishing its insulating properties.

A professional glazier can repair a damaged window seal with a brand new one. However, this could be expensive and may not solve the fog problem entirely. Some companies offer defogging, which involves placing an air pump inside the frame of the window repairs to eliminate moisture and make the glass clear. This method is not foolproof and glazing doesn't replace inert gasses, which means that the fog may come back.

If the IGU (insulated unit) is beyond repair, a glazier could replace it. This is the most cost-effective option and can be a great choice if you are looking for a long-term solution. However, it's best to choose a company that offers a warranty for replacement windows to ensure that any issues are covered. You can be certain that your investment will produce the best results. Alternately, you can attempt to avoid this issue by choosing a high-quality window and following the manufacturer's care instructions. This will prolong the lifespan of your window and reduce the need for repairs.
