Double Glazed Windows Repairs
There are a variety of reasons your double-glazed windows may require repair including condensation between panes to drop or sagged frames. The majority of these issues can be resolved.
Try applying lubrication to the hinges, handles and mechanism of your window or door in case it is hard to open. This is usually a simple, short-term fix.
Broken Panes
If a window pane breaks, it loses its insulating properties and could cause a draft. If the muntins that separate the glass panes are also broken, water can leak between them causing condensation, mould or mildew. This can make your home less energy-efficient. A window that is damaged should be repaired by an expert to ensure you get a proper seal and optimum energy efficiency.
In the beginning, you'll have to take the broken glass off. Start by placing an inexpensive glass cutter from an appliance store beneath the broken pane. Before starting, you should grease the cutter of this tool with an oil that is light. This will help prevent the glass from breaking too easily. You can then use the tool's ball-shaped end to loosen the pieces and they should fall off fairly quickly.
After the glass has been removed, scrape any glazing compound that is old from the recess area of the frame. This will reveal the glazier's points and metal clips that keep the pane in the frame. If there's any indication of corrosion, these should be replaced with new ones. If the window is made of wood the glazier points may be reused if they are still intact.
The surface of the remaining frame needs to be prepared to allow re-glazing. Apply a continuous strip compound to the recess using the caulking tool. Use a high-quality putty, such as a Glazier's compound that is contained in cartridge. Allow it to dry before re-inserting the glass. If the frame has metal clippings, they should be reinstalled too. Install the dividers.
Condensation
Condensation is one of the most common issues that double-glazed windows may experience, especially in the wintertime. This is usually caused by too many moisture levels within your home. Warm air meets cold glass and condenses to droplets of water. These then collect in the corners and frame of the window. You can prevent this from happening by opening your windows more frequently and improving ventilation with extractor fans, and utilizing dehumidifiers. If condensation is still present you should contact an expert who will be able to pinpoint the issue and fix or replace the windows if necessary.
It's also important to note that condensation on double-glazed windows can actually be an indication of a failing seal. This is because the factory applied vacuum seal can break down over time and allow cool air to flow between the panes. This can cause fogging of the window, and eventually mold growth if it is not addressed quickly enough.
Hairdryers can be used for a quick way to eliminate excess moisture. This is only a temporary solution and should only be used as a last option. If the condensation has been left for too long, you could be looking at mould or dampness in your home, which must be addressed by a specialist.
For a more long-term solution you can get your double-glazed windows sealed by experts. They'll remove the affected piece of glass, clear the gap and pipe into hot air to evaporate any moisture that remains. During the process, they'll also inspect for any signs of damage, mildew or mould growth and apply a draught proofing treatment to ensure that your windows are fully functional and energy-efficient once again.
Draughts
The rubber seals wear out in time and create drafts between the two panes. It is simple to replace the gaskets that will form an airtight seal. This will keep warm air in your home, and the colder air out, saving you money on your energy bills.
Double glazing that is misted may be an indication of blow-blown seals. The unit is comprised of two panes of glass filled with argon separated by a spacer to create an airtight window. If the seal is blown, water vapour will enter your room via the gap. This will create condensation between the glass panes which is not able to be removed.
This is a simple issue to fix, and windows can be quickly repaired by professionals using the right tools. The expert will employ tools designed to push the new seals into position and this is normally quicker than attempting to do it manually. The tools also have a pointed end that can be helpful for pushing seals into the corners.
In certain situations an expert might be able to "reseal your windows' by drilling a small hole in the window and adding the desiccant material, or putty. This is less expensive 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 issue that many people face. It could be caused by cracked or broken glass or frame or even a broken seal. The good news is that it is often repaired. This typically involves creating a seal between the two glass panes. The new seal will stop condensation, draughts, and leaks from happening.
You should contact the company through which you purchased your windows and let them know of any problems immediately you spot them. It is important to notify the company in writing and request confirmation that they received your notification. If there are any disputes, having everything in writing will aid in proving your claim.
A window repair expert may drill the gap between your windows to remove moisture and make an airtight seal. This is a temporary fix that won't stop moisture from returning. In addition, it might be possible to replace the glass unit itself which will ensure it is watertight.

Broken Seals
Double-glazed windows are held in place by seals for windows or insulation gas. They are susceptible to damage due to various factors, including weather conditions, age and power washing. It is important to recognize the signs and how to repair them.
When a window seal fails it allows humidity to get into the two glass panes, causing fog. It's a frequent issue and it can cause the window to look visually disoriented. Once the seal fails, gas like argon as well as other inert gases are lost from the window, thereby diminishing the glass's insulation capabilities.
A professional glazier can replace a broken window seal with a new one. However, this is expensive and may not solve the fog problem entirely. Certain companies offer defogging, which involves putting a vacuum pump inside the window frame in order to remove moisture and clear the glass. This method isn't 100% reliable, and it doesn't replace inert gasses, which means that the fog may be re-created.
If the IGU (insulated unit) is damaged beyond repair, a glazier could replace it. This is usually the most cost-effective option, and is a great option in the event you're looking for a long-term solution. It is best to choose a company who offers a warranty on replacement windows. This will ensure that any issues you may have are covered. This means you can be sure that you'll get most value from your investment. You can also try to avoid the problem by selecting an item of high-quality and following the maintenance instructions provided by the manufacturer. This will prolong the lifespan of your window and minimize the need for repairs.
