Double glazed windows can need repair for many reasons, including condensation between the panes, draughts or frames that are sagging. Fortunately, a majority of these issues can be resolved.
If your window or door is difficult to open, try oiling the hinges, the mechanism and handles. This is a quick, cheap fix.
Broken Panes
When a window is broken it loses its insulation properties and could cause draft. If the dividing muntins are also broken, it could cause moisture to leak through the glass panes resulting in condensation, mould and mildew and making your home less efficient in energy use. A broken window is best repaired by an expert to ensure you get a perfect seal and the optimum energy efficiency.
First, you'll need to take out any broken glass. Start by placing a low-cost glass cutter in an appliance store beneath the broken pane. It's recommended to lubricate the cutter with light oil prior to when you begin. This will stop the glass from shattering too easily. The ball-shaped tip of the tool can be used to break the fragments. They should fall off quite quickly.
Scrape any old glazing compound out of the recess of the frame after the glass is removed. This will reveal the glazier's points and the metal clips that hold the pane in place. Replace them if you notice any corrosion. If the window is wooden the glazier's gilder's points can be used again if they're intact.
The next step is to prepare the surface of the remaining frame for reglazing. Apply a continuous strip compound to the recess with the caulking tool. Make use of a premium putty like glazier's compound that is available in a cartridge or a conventional compound sold in a can. Allow it to dry prior to re-inserting the glass. Install the metal clips if they are on the frame. Then, you can install the dividers.
Condensation
Condensation is a concern for double-glazed windows, especially during the winter. It's usually caused by high moisture levels in your home. Warm air meets cold glass, which condenses into water droplets. These then collect in the corners and frame of the window. This can be prevented by opening windows more frequently and improving ventilation by installing extractor fans, and using dehumidifiers in order to reduce the amount of moisture. If condensation is still an issue, it's crucial to call in a professional to get to the root of the issue. You can then fix or replace your windows when necessary.
Condensation in a double-glazed glass window is a sign that the seal has failed. This is due to the factory applied vacuum seal will be damaged over time, allowing cool air to make its way between the panes. This can cause the window to become cloudy and eventually develop mold if not addressed immediately.
Hairdryers can be used for a quick way to eliminate excess moisture. This is a temporary solution and should be used only as a final alternative. If you allow the condensation to sit for too long, it may lead to mould or dampness in your home. This issue should be handled by a professional.
For a more long-term solution you can have your double-glazed windows repaired by professionals. They will remove the affected glass pane, clean the gap and pipe hot air into the space to eliminate any moisture. In the process, they'll look for signs of the presence of mildew, mold or damage growth, and then apply a draught-proofing treatment to ensure your windows are fully operational and energy efficient again.
Draughts
Rubber seals can get worn out over time and cause drafts between the two panes. This is typically a simple problem that can be solved by re-installing the gaskets and this will result in a solid and airtight seal once again. This will keep the warm air inside 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 composed of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal has blown it allows water vapour to pass through your home through the gap, which will cause condensation between the panes which can't be removed.
Fortunately, this is an easy problem to fix, and windows can be replaced very quickly by specialists 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 is generally faster than doing it manually. These tools have an edge that can be used to push seals into corners.
In some cases an expert might be able to "reseal' your windows by drilling a small hole in the window and then putting in a special desiccant material or putty. This is a less expensive option than replacing your double-glazed windows and still provides you with a reliable draught proofing system.
Faulty Hinges
Many people have experienced misted double glazing. It can be caused by a cracked or broken glass or frame, or even a broken seal. It is often possible to correct this issue. Typically, this is done by creating an entirely new seal between the two glass panes. The new seal will stop condensation, draughts, as well as leaks.
Contact the company from whom you purchased your windows and inform them of any issues as soon as you notice them. Be sure to do this in writing, and ask them to confirm that they've received your message. If there is a dispute the fact that everything is written will make it easier to prove your complaint.
In some instances, a window repair specialist will drill the gap in your windows to draw out moisture and create an entirely new seal. This is a temporary fix and will not stop the return of moisture. It might also be possible to replace the glass unit, which will make it watertight.
It is crucial to remember that you should only try DIY fixes when you have the skills and know-how required to make the attempt. Utilizing super glue or any other kind of DIY solution could cause more harm in the long term. If you aren't sure what to do, it's always better to seek professional advice.

Broken Seals
Double-glazed windows are secured by seals on windows or gas. A variety of factors can cause them to break, including the weather, age, and power washing. It's crucial to be aware of what the signs are and how to repair them.
When a window seal fails, it allows humid air to get into the two glass panes, causing fog. It's a common problem, and it can cause the window to look visually altered. When the seal fails the argon or any other inert gas will be removed from the glass, reducing its insulating properties.
A broken window seal can be fixed by replacing it with a a new one by an experienced glazier. However, this can be expensive and may not resolve the fog problem entirely. Certain companies offer defogging solutions that involve putting an air pump inside the window frame to remove the moisture and leave the glass free of fog. However this method isn't foolproof and doesn't replace any inert gases, meaning that the fog can come back.
If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is typically the most cost-effective solution and can be a good choice when you're looking for an option that lasts for a long time. It's best to select a company who offers warranties on replacement windows. This guarantees that any issues that you might encounter are covered. You can be assured that your investment will yield the most effective results. You can also avoid this issue by choosing a high-quality product and following the maintenance instructions given by the manufacturer. This will extend the lifespan of your window and minimize the need for repairs.
