Double Glazed Windows Repairs
There are a variety of reasons your double-glazed windows could require repairs, from condensation between panes to draughts and dropped or sagged frames. Fortunately, a majority of these issues can be resolved.
If your window or door is difficult to open, consider oiling the hinges, the mechanism and handles. This is a quick and affordable solution.
Broken Panes
When a window is damaged it loses its insulation and may cause drafts. If the dividing muntins are also damaged, it could cause moisture to leak through the glass panes, leading to condensation, mildew and mould and making your home less energy efficient. A broken window is best repaired by a professional to ensure you get the correct seal and maximum energy efficiency.
The first step is to get rid of any broken glass. Begin by placing a cheap glass cutter from an appliance store beneath the broken pane. It's a good idea to grease the cutter with a light oil before you begin. This will help prevent the glass from breaking too easily. You can then make use of the tool's ball-shaped tip to break up the glass fragments and the glass should break away quickly.
Scrape any old glazing compound off the frame's recess after the glass is removed. This will reveal the metal clips and glazier's pins that hold the glass in place. Replace them if you notice any corrosion. If the window is made of wood the glazier points may be reused if they're still in good condition.
You'll need to prepare the surface of the frame for reglazing. Apply a continuous strip compound to the recess with a caulking tool. Make use of a premium putty such as glazier's compounds that is contained in a cartridge or a conventional compound that is sold in a can. Dry it out before installing the glass. If the frame has metal clippings, they must be removed as well. Then, you can install the dividers.
Condensation
Condensation can be a problem for double-glazed windows, especially in winter. It's typically caused by excessive moisture in the house, with warm air meeting cold glass, which condenses into water droplets and collects in the corners of your windows or across the frame. You can avoid this by opening your windows more often and improving ventilation with extractor fans, and using dehumidifiers. If condensation persists, you should call a professional who can diagnose the issue and repair or replace the windows if necessary.
Condensation in a double-glazed glass window is a sign that the seal has failed. The seal that is applied by the factory may wear away over time and allow cool air to get between the panes. This can cause fogging of the window and eventually, mold growth if it is not addressed promptly enough.
A hairdryer can be used for a quick way to get rid of excess moisture. However, this is just an interim solution and should be used as a last option. If the condensation has been allowed to sit for too long it may be experiencing mould or dampness within your home, which needs to be addressed by a professional.
As a longer-term solution, you can get your double-glazed windows sealed by professionals. They'll take off the affected pane of glass, clear the gap, and then pipe into hot air to evaporate any moisture that remains. During the process, they will also look for any signs of damage, mildew or mould growth, and perform a draught proofing treatment to ensure that your windows are functional and energy efficient.
Draughts
Rubber seals may wear down over time and create a draft between your two panes. It's an easy fix to replace the gaskets, that will form an airtight seal. This will allow warm air inside your home and the colder air out, saving you money on your energy bills.
Misted double glazing indicates that the seals inside your sealed unit (sometimes called a DGU) have blown. The unit is comprised of two panes of glass separated by the spacer bar to create an insulating gap. Then, it is filled with gas, like argon to make the window airtight. If the seal has blown it allows water vapour to enter your room through the gap, causing condensation between the panes that can't be removed.
Fortunately it is a simple issue to fix and the windows can be replaced quickly by professionals who have all the right tools and know how to do it correctly. The expert will employ an instrument designed to push the new seals into place and this is normally quicker than trying to do it manually. These tools have an edge that can be used to push seals into corners.
A professional may be able'reseal your windows by drilling a small opening into the window and then adding a desiccant, or putty. This is a cheaper solution than replacing your double glazing and still provides you with a reliable Draught-proofing system.
Faulty Hinges
Misted double glazing is a typical issue that many people face. This can be caused by cracked or broken glass or frame or even a damaged seal. It is often possible to correct this issue. This typically involves making a seal between the two glass panes. The new seal will prevent condensation, draughts, as well as leaks.
If you spot any problems, you should contact the company that sold you the windows. Make sure to put this in writing and ask them to confirm that they have received your message. Having everything in written form will make it easier to resolve any disputes arise, since it will be easier to prove that you actually complained.
In certain situations the window repair expert will cut the hole in your windows to draw out moisture and make a new seal. However, this is usually only temporary and will not stop moisture from returning. It is also possible to replace only the glass part, which will make it watertight.
It is important to keep in mind that you should only try DIY fixes when you have the skills and experience required to make the attempt. Super glue or other DIY solutions can cause more damage over the long term. It is always best to seek help from a professional when double glazing repairs you aren't sure what to do.

Broken Seals
Window seals, or insulation gas fills, are what hold double-glazed windows in place. They are susceptible to damage due to various elements, including weather conditions, age and power washing. It is crucial to know the symptoms and how to repair them.
If a window seal is damaged humid air can leak between the two panes of glass, causing fog. This is a common problem that can make the window appear distorted. When the seal is damaged, gas like argon as well as other inert gases are lost from the window, thereby reducing the glass's insulating qualities.
A professional glazier can replace a broken window seal with a new one. This is costly and may not solve the fog issue. Certain companies offer defogging services, which involve placing the vacuum pump of a specific type inside the window frame to remove the moisture, leaving the glass clean. This method isn't 100% reliable and does not replace inert gasses, so the fog can return.
A glazier can also replace the entire IGU (insulated glass unit) if it is beyond repair. This is the most cost-effective solution and can be a great choice if you are seeking a long-term solution. It is recommended to select a company that offers a warranty for replacement windows to ensure that any problems are covered. You can be sure that your investment will provide the most effective results. Alternatively, you can attempt to avoid this issue by choosing a high-quality window and following the manufacturer's maintenance instructions. This will extend the life of the window and decrease the number of repairs.
