Double Glazed Window Repairs
Double glazing can be a great investment, but it can be frustrating when it doesn't perform. Most issues can be fixed and you don't need to replace windows or doors.
Double-glazed windows consist of two glass panes that are separated by a small gap. The gap is then filled with an insulating gas like the gas argon. This improves the efficiency of windows.
Broken panes
While double-pane windows are more resistant to breaking than single-pane glass, they may crack or shatter. It is crucial to repair the broken pane of double glazing as quickly as you can to prevent moisture and energy loss.
Depending on the extent of the crack you can choose to use a temporary fix or opt for an intensive epoxy repair. A temporary repair will help to prevent further cracking and will keep out rain and cold air. A more extensive repair will strengthen the crack, and provide an even stronger seal.
To replace a double-pane broken window, take the frame off and place it on a flat surface. Install a grid of duct tape over the pane in order to prevent any glass fragments from falling off during removal. Once the tape is secured then pull the old double pane glass out of the frame. Then, clean the rabbet and grooves using a wire brush and vacuum or wipe with a damp cloth. Remove the wood molding if needed and scrape off all putty or metal glazing points prior to installing the new pane. Then, apply a silicone caulk to the grooves and rabbet to ensure a secure fit.
If you're trying to repair a damaged glass by yourself, begin by sanding it until it is smooth and free of paint. Heating guns can be used to soften any glazing or putty points. After the rabbet is cleaned and dried, you can use a putty knife to press the rope into position. Make sure that the putty is of an even thickness, and that it presses evenly against the glass and frame.
If you're looking for a long-term fix an epoxy repair is a better choice over replacing. This requires more work and a longer time to wait, but it can be more appealing and will last much longer than a quick temporary repair.
Condensation
Condensation is a typical issue with double-glazed windows however, it doesn't mean that they are defective. It's a good thing your windows display condensation. This means that the double glazing is functioning just as it should, keeping out the cold and keeping in the heat.
It's actually water vapour from your home that forms a layer on the glass's surface when you notice condensation. It's a natural process that isn't harmful to your windows unless you leave it on the glass for long enough.
Internal condensation is often caused by excessive humidity in the room or the low internal temperatures, which causes cold surfaces like the windows to attract moisture from the air that has high dew points (the temperature at which water changes into a liquid). The steam from showers, kettles and hot pots and cookers can also cause humidity around bathrooms and kitchens.
To avoid condensation, make sure not to hang wet clothes near your windows and always ensure that your uPVC frames have plenty of air circulation to avoid the accumulation of moisture. It is also important to ensure that your double glazed windows are properly insulated and fitted with the proper gap (6mm is best) to ensure maximum energy efficiency. You can also try installing one-way air vents on your windows to further improve insulation. If you still get condensation, there is likely the issue is with your seals or gaskets. This is a job best left to professionals.
Draughts
A draughty double-glazed window is an indication that the seal between the glass panes has failed and will need to be replaced. This could affect the insulation of your home and cause an increase in your energy bills and therefore it is important to act quickly when you spot this issue.
Window repair services can replace your sealed unit, restoring efficiency to your windows. They can also upgrade your existing frames with energy-saving features, like glass units that are filled with argon, as well as thermal spacer bars to cut down on heat loss, and lower your heating costs.
Draughts can be caused by problems with the locking mechanisms of double glazed windows, so it's worth getting these checked. Older uPVC window locks are notorious for becoming stiff with time, but it's easy to fix this issue by applying regular oiling with an expert uPVC cleaning product.

Smudging
Double-glazed windows are made up of two panes that have an air or spacer dense gas between them to make an effective seal that stops heat from passing through the frame. They're an excellent choice to save energy and reduce the carbon footprint of your home. However, double glazing may have a range of issues that may affect its performance and longevity. This includes condensation, fog and difficulty closing or open.
If you're having difficulty opening your double-glazed windows, it could be due to the weather. It could also be a issue with the hinges, or handles. Wiping them down with cold water and then lubricating them may help solve the issue, however you must contact the company that you purchased your windows from as soon as possible to have it fixed.
This is a common issue that is easily fixable. It is also worth checking the warranty to determine what, if any, repairs are covered under this.
Foggy and fogged glass can be caused by condensation between the panes. It's usually the result of seals that are not working or an old double-glazing unit that needs replacing. It's a fairly simple fix and often you can get it done without the need to replace the entire window, which will reduce the cost of replacement.
To resolve this issue the technician will drill small holes to vent any moisture between the glass and the rest the window. When the moisture is gone then a new anti-fog coating will be applied and the window sealed. Sometimes the window will need to be taken off but, in most instances, it can be done at home.
Mist
Double glazing that is older can have a mist issue particularly when it happens both within and outside the window. This is caused by a failure in the seal that is designed to hold air and moisture out between the two panes. This seal is created during the production of double-glazed units by sealing the two panes using an airtight polysulphide or butyl seal around the edges and a spacer bar. This seal is designed to keep the window from leaking, and also provide insulation. It isn't easy to clean windows with mist because you have to break the seal to do so.
The issue with mist is that it lets moisture to get in, which then results in condensation between the glass panes. The reason for this is that there is a big difference in temperature between the internal and exterior surfaces of the glass. The moisture is then trapped within the spaces and gives an appearance of milky white. This can be extremely unsightly and difficult to remove.
There are a number of companies that claim to be able to repair your double glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes. Then, they absorb the moisture inside. This isn't an end-to-end solution and it's much easier to replace the entire double-glazed unit.
The best way to avoid double glazing that is smudgey is by making sure you have adequate ventilation and cleaning your windows regularly. Make use of extractor fans to minimize the amount of moisture that accumulates in bathrooms and kitchens. Wipe down local window repair shop with a wet cloth to avoid this. If you're not able to eliminate the problem completely We recommend replacing your double-glazed units with new A-rated units to increase the efficiency of your energy usage.
