Double Glazed Windows Repairs
Double-glazed windows may require repair for a variety of reasons, like condensation between the panes, draughts or frames that are sliding. The majority of these issues are fixable.
Try applying lubrication to the hinges, handles and mechanisms of your door or window if it is difficult to open. This is usually a simple, short-term fix.
Broken Panes
When a window pane is damaged it loses its insulation properties and could cause draft. If the dividing muntins are also broken it can cause water to leak through the glass panes, leading to condensation, mildew and mould and making 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.
The first step is to remove any broken glass. Begin by placing a cheap glass cutter in an hardware store underneath the broken pane. It's a good idea to grease the cutter with a light oil before you begin. This will stop the glass from breaking too easily. The ball-shaped tool can be used to break the fragments. They should fall off quite quickly.
Scrape any old glazing compound off the recess of the frame once the glass has been removed. This will expose the glazier's clips and pins that keep the glass in the frame. If there's any indication of corrosion, these clips should be replaced with new ones. 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 remaining frame for reglazing. Utilizing a caulking gun apply a continuous ribbon of compound around the inside edge of the recess. Make use of a premium putty such as a glazier's compound that is contained in a cartridge or a conventional compound sold in a can. Let it dry before re-inserting the glass. If the frame has metal clippings, they must be removed as well. Finally, reinstall the divider muntins.
Condensation
Condensation is a common problem that double-glazed windows face particularly in wintertime. It's typically caused by too much moisture in the home, with warm air meeting cold glass, which condenses into water droplets and then collects in the corners of your windows or across the frame. It can be prevented by opening windows more regularly and enhancing ventilation with extractor fans, and using dehumidifiers to reduce moisture levels. If condensation is still present it is recommended to contact an expert who will be able to pinpoint the problem and repair or replace the windows if required.
Condensation on a double-glazed glass window is a sign the seal has failed. The seals that are applied at the factory may wear away over time and allow cool air to get between the panes. This can lead to fogging of the window and eventually mold growth if it is not addressed quickly enough.
Hairdryers can be used as a quick solution to eliminate excess moisture. However, this is only an interim solution and should only be used as an option last resort. If the condensation has been left for a long time it could be looking at mould or dampness in your home, which needs to be addressed by a professional.
Professionals can reseal your double-glazed window for a more permanent solution. They'll remove the affected pane of glass, then clean the gap, and then pipe in hot air to evaporate any moisture that remains. During this process, they'll also examine for any the presence of mildew, mold or damage growth, and then apply a draught-proofing process to ensure that your windows are functional and energy efficient once again.
Draughts
Rubber seals can get worn out over time and create drafts between the two panes. This is often a simple issue that can be resolved by replacing the gaskets and this will result in a solid and airtight seal. This will keep warm air inside your home and cooler air out. You will reduce your energy bills.
Double glazing that is misted could be a sign of blown seals. The unit is composed of two panes of argon-filled glass separated by a spacer to form 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 is not able to be removed.
Fortunately, this is an easy problem to fix, and windows can be replaced quickly by experts who have all the right tools and know how to do it upvc repair correctly. The expert will employ a tool designed to push the new seals in place and it is usually faster than doing it manually. These tools also have a pointed end that can be helpful for pushing the seals into the corners.
A professional could be able to seal your windows by drilling a small opening into the window, and adding a desiccant or putty. This is a cheaper solution than replacing your double-glazed windows and will still provide you with a reliable air-tight system for draughtproofing.
Faulty Hinges
Misted double glazing is a typical problem that many people encounter. It could be caused by cracked or broken glass or frame, or even a broken seal. The good news is that it can be easily fixed. This typically involves making a seal between the two glass panes. The new seal will prevent condensation, draughts and leaks from happening.
If you spot any issues, you must contact the company that sold you your windows. You should inform the company in writing and ask for confirmation that they have received your notice. Having everything in written form will help later on should any disputes arise, because it will be easier to prove that you did complain.
In some instances the window repair expert may be able to drill a hole in your windows to draw out moisture and create a new seal. This is a temporary fix and will not stop moisture from resurfacing. Alternatively, it may be possible to replace the glass unit itself which will ensure that it is watertight.
It is important to keep in mind that you should only experiment with DIY fixes if you have the skills and know-how required to be able to do it. Super glue or other DIY solutions could cause more damage over the long term. It is best to seek professional help if you are unsure what to do.

Broken Seals
Window seals, or insulation gas fills, are what keep double-glazed windows in place. A variety of factors can cause them to break, including weather conditions, age and power washing, so it's essential to be aware of what symptoms are and how to fix them.
When a window seal fails humid air can leak between the two panes of glass, creating fog. This is a common issue, and it can also cause the window to look visually disoriented. If the seal is damaged the argon or any other inert gas will be removed from the glass, diminishing its insulating properties.
A damaged window seal can be repaired by having it replaced with an entirely new one by a professional glazier. However, this is expensive and may not solve the fog issue completely. Some companies offer defogging, which involves placing an air pump inside the window frame in order to remove moisture and make the glass clear. This method is not foolproof, and it doesn't replace inert gasses, so the fog can return.
If the IGU (insulated unit) is damaged beyond repair, a glazier can replace it. This is usually the most cost-effective option and could be a good option when you're seeking an option that lasts for a long time. It's best to select a company who offers warranties on replacement windows. This will ensure that any issues that you might encounter are covered. You can be sure that your investment will produce the best results. Alternately, you can attempt to avoid this issue by choosing a premium window and following the manufacturer's maintenance instructions. This will extend the life of your window and minimize the need for repairs.
