Double Glazed Window Repairs
Double glazing is an excellent investment, but it can also be it can be frustrating when it doesn't perform. Most issues can be fixed and you don't have to replace windows or doors.
Double-glazed windows are made up of two glass panels separated by a very thin gap, filled with an insulating gas such as argon or krypton. This improves the efficiency of windows.
Broken panes
Double-pane windows are resistant to breaking than single-pane glass, they are still able to crack or shatter. It's important to fix any broken panes in double glazing as soon as possible to avoid the loss of energy and moisture.
You can opt for a temporary repair or a more extensive epoxy fix based on the severity of your crack. A temporary repair will aid in preventing further cracks, and keep out rain and cold air. A more extensive repair could strengthen the crack and provide more secure seal.
To replace a double-pane damaged window, take the frame off and place it on a flat surface. Install a grid of duct tap over the pane to prevent any glass fragments from falling during removal. Once the tape is in place then pull the old double pane glass off of the frame. Then employ a wirebrush to clean the grooves and rabbets. You can also vacuum or wipe them clean with a damp cloth. Remove the wood molding, if required and scrape off all putty or metal glazing points prior to installing the new pane. Apply silicone caulk into the rabbets and grooves to ensure a tight fit.
If you're looking to fix a cracked window yourself, begin by sanding the rabbet until it's smooth and free of gunk or paint. Heat guns can be used to soften any putty or glazing. After the rabbet has been cleaned, a putty knife can be employed to press a rope of putty into place. Make sure the putty has a uniform thickness and presses against the glass and the frame evenly.
If you prefer a long-term fix an epoxy repair is a better choice over replacing. This option is more expensive and will require a longer wait time, but can be more appealing. It will also last longer than a temporary fix.
Condensation
Condensation is among the most frequent double-glazed window issues, however it doesn't necessarily mean that your windows aren't working properly. The fact that your windows are showing condensation is actually a good indicator that your double glazing is doing what it's supposed do, keeping the cold out and letting warmth in.
If you notice condensation appearing on the outside of your window it is actually water vapor coming from the inside of your home that has been cooled and condensed on the surface of the glass. It's a natural process that isn't harmful to your windows, unless you leave it on the glass for long enough.
The reason for condensation inside is usually too much humidity or low temperatures in the room. This causes cold surfaces, like windows which draw in moisture with a high in dewpoint (the temperature at which water transforms into liquid). The humidity is also a common occurrence in kitchens and bathrooms because of steam from kettles or showers as well as hot pots and pans used in cooking.
To avoid condensation, try not to hang wet clothes near your windows and always ensure that your uPVC frames have plenty of air circulation to stop the accumulation of moisture. You should also ensure that your double-glazed windows are properly insulated and fitted with the proper gap (6mm is the ideal) to maximize energy efficiency. You could also try installing one-way air vents on your windows to further improve insulation. If you still get condensation, it's likely the issue is with your gaskets or seals. This is a task best left to a professional.
Draughts
A window that isn't properly sealed can be an indication that the seal between your glass panes has failed and will require to be replaced. This can affect the insulation of your home and result in an increase in your energy bills and therefore it is important to act fast when you spot this issue.

It's also worth checking the locking mechanisms on your double-glazed windows. Older uPVC window locks are known for becoming stiff over time, but it's easy to fix this issue by applying regular oiling with a specialist uPVC cleaning product.

Smudging
Double-glazed windows consist of two separate panes with an air spacer or dense gas between them to form an effective seal that stops heat passing through the frame. They are a great way to save energy and reduce the carbon footprint of your home. However, double glazing can experience a variety of issues that can affect its performance and durability. These include condensation, mist, and difficult to open or close.
Inability to open your double-glazed windows could be due to the weather or it could be due to a problem with the hinges, handles or mechanism. Wiping them clean with cold water and then lubricating them can solve the issue, however you should contact the manufacturer that you purchased windows from as soon as possible to get it fixed.
This is a common issue which can be easily fixed. It is always worth checking your warranty to see whether any repairs are covered.
Fogged or foggy glass is caused by moisture between panes. It's usually a sign that the seals aren't working properly or that the double-glazing system needs to be replaced. This is a straightforward solution that can be achieved without having to replace the whole window.
To address this issue the technician will make small holes to let out any moisture between the glass and the window. After the moisture has been removed, a new antifog coating is applied and the window is sealed. Sometimes, the window will require removal prior to this can happen but the majority of the time, it can be done within the home.
Mist
Double glazing that is older may be prone to mist particularly when it occurs both within and outside the window. This is due to a failure of the seal designed to block moisture and air between the two panes. In the production of double-glazed units, this seal is created by sealing both panes using an airtight butyl or polysulphide seal around the edges of the glass and a spacer bar. This seal is designed to keep the window from leaking, and also provide insulation. If you have misted double-glazed windows, it may be difficult to take off and clean, as you'll have to break the hardened seal in order to clean.
The issue with mist is that it allows 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 glass surfaces. The water is then absorbed within the spaces and gives the appearance of a milky white. This can be very unsightly and difficult to remove.
There are upvc repairs who claim that they can fix your double glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes which then absorbs the moisture inside. It's not an end-to-end solution and it's easier to replace the entire double-glazed unit.
The best way to avoid misty double glazing is by maintaining a high level of ventilation and regularly cleaning your windows. Make use of extractor fans to minimize the amount of moisture that accumulates in kitchens and bathrooms. Clean windows with a wet cloth to prevent this. If you can't avoid the problem, we recommend replacing windows that are double-glazed with A-rated windows to increase the efficiency of your energy bills.
